GNU GENERAL PUBLIC LICENSE
|
2 |
+
Version 3, 29 June 2007
|
3 |
+
|
4 |
+
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
5 |
+
Everyone is permitted to copy and distribute verbatim copies
|
6 |
+
of this license document, but changing it is not allowed.
|
7 |
+
|
8 |
+
Preamble
|
9 |
+
|
10 |
+
The GNU General Public License is a free, copyleft license for
|
11 |
+
software and other kinds of works.
|
12 |
+
|
13 |
+
The licenses for most software and other practical works are designed
|
14 |
+
to take away your freedom to share and change the works. By contrast,
|
15 |
+
the GNU General Public License is intended to guarantee your freedom to
|
16 |
+
share and change all versions of a program--to make sure it remains free
|
17 |
+
software for all its users. We, the Free Software Foundation, use the
|
18 |
+
GNU General Public License for most of our software; it applies also to
|
19 |
+
any other work released this way by its authors. You can apply it to
|
20 |
+
your programs, too.
|
21 |
+
|
22 |
+
When we speak of free software, we are referring to freedom, not
|
23 |
+
price. Our General Public Licenses are designed to make sure that you
|
24 |
+
have the freedom to distribute copies of free software (and charge for
|
25 |
+
them if you wish), that you receive source code or can get it if you
|
26 |
+
want it, that you can change the software or use pieces of it in new
|
27 |
+
free programs, and that you know you can do these things.
|
28 |
+
|
29 |
+
To protect your rights, we need to prevent others from denying you
|
30 |
+
these rights or asking you to surrender the rights. Therefore, you have
|
31 |
+
certain responsibilities if you distribute copies of the software, or if
|
32 |
+
you modify it: responsibilities to respect the freedom of others.
|
33 |
+
|
34 |
+
For example, if you distribute copies of such a program, whether
|
35 |
+
gratis or for a fee, you must pass on to the recipients the same
|
36 |
+
freedoms that you received. You must make sure that they, too, receive
|
37 |
+
or can get the source code. And you must show them these terms so they
|
38 |
+
know their rights.
|
39 |
+
|
40 |
+
Developers that use the GNU GPL protect your rights with two steps:
|
41 |
+
(1) assert copyright on the software, and (2) offer you this License
|
42 |
+
giving you legal permission to copy, distribute and/or modify it.
|
43 |
+
|
44 |
+
For the developers' and authors' protection, the GPL clearly explains
|
45 |
+
that there is no warranty for this free software. For both users' and
|
46 |
+
authors' sake, the GPL requires that modified versions be marked as
|
47 |
+
changed, so that their problems will not be attributed erroneously to
|
48 |
+
authors of previous versions.
|
49 |
+
|
50 |
+
Some devices are designed to deny users access to install or run
|
51 |
+
modified versions of the software inside them, although the manufacturer
|
52 |
+
can do so. This is fundamentally incompatible with the aim of
|
53 |
+
protecting users' freedom to change the software. The systematic
|
54 |
+
pattern of such abuse occurs in the area of products for individuals to
|
55 |
+
use, which is precisely where it is most unacceptable. Therefore, we
|
56 |
+
have designed this version of the GPL to prohibit the practice for those
|
57 |
+
products. If such problems arise substantially in other domains, we
|
58 |
+
stand ready to extend this provision to those domains in future versions
|
59 |
+
of the GPL, as needed to protect the freedom of users.
|
60 |
+
|
61 |
+
Finally, every program is threatened constantly by software patents.
|
62 |
+
States should not allow patents to restrict development and use of
|
63 |
+
software on general-purpose computers, but in those that do, we wish to
|
64 |
+
avoid the special danger that patents applied to a free program could
|
65 |
+
make it effectively proprietary. To prevent this, the GPL assures that
|
66 |
+
patents cannot be used to render the program non-free.
|
67 |
+
|
68 |
+
The precise terms and conditions for copying, distribution and
|
69 |
+
modification follow.
|
70 |
+
|
71 |
+
TERMS AND CONDITIONS
|
72 |
+
|
73 |
+
0. Definitions.
|
74 |
+
|
75 |
+
"This License" refers to version 3 of the GNU General Public License.
|
76 |
+
|
77 |
+
"Copyright" also means copyright-like laws that apply to other kinds of
|
78 |
+
works, such as semiconductor masks.
|
79 |
+
|
80 |
+
"The Program" refers to any copyrightable work licensed under this
|
81 |
+
License. Each licensee is addressed as "you". "Licensees" and
|
82 |
+
"recipients" may be individuals or organizations.
|
83 |
+
|
84 |
+
To "modify" a work means to copy from or adapt all or part of the work
|
85 |
+
in a fashion requiring copyright permission, other than the making of an
|
86 |
+
exact copy. The resulting work is called a "modified version" of the
|
87 |
+
earlier work or a work "based on" the earlier work.
|
88 |
+
|
89 |
+
A "covered work" means either the unmodified Program or a work based
|
90 |
+
on the Program.
|
91 |
+
|
92 |
+
To "propagate" a work means to do anything with it that, without
|
93 |
+
permission, would make you directly or secondarily liable for
|
94 |
+
infringement under applicable copyright law, except executing it on a
|
95 |
+
computer or modifying a private copy. Propagation includes copying,
|
96 |
+
distribution (with or without modification), making available to the
|
97 |
+
public, and in some countries other activities as well.
|
98 |
+
|
99 |
+
To "convey" a work means any kind of propagation that enables other
|
100 |
+
parties to make or receive copies. Mere interaction with a user through
|
101 |
+
a computer network, with no transfer of a copy, is not conveying.
|
102 |
+
|
103 |
+
An interactive user interface displays "Appropriate Legal Notices"
|
104 |
+
to the extent that it includes a convenient and prominently visible
|
105 |
+
feature that (1) displays an appropriate copyright notice, and (2)
|
106 |
+
tells the user that there is no warranty for the work (except to the
|
107 |
+
extent that warranties are provided), that licensees may convey the
|
108 |
+
work under this License, and how to view a copy of this License. If
|
109 |
+
the interface presents a list of user commands or options, such as a
|
110 |
+
menu, a prominent item in the list meets this criterion.
|
111 |
+
|
112 |
+
1. Source Code.
|
113 |
+
|
114 |
+
The "source code" for a work means the preferred form of the work
|
115 |
+
for making modifications to it. "Object code" means any non-source
|
116 |
+
form of a work.
|
117 |
+
|
118 |
+
A "Standard Interface" means an interface that either is an official
|
119 |
+
standard defined by a recognized standards body, or, in the case of
|
120 |
+
interfaces specified for a particular programming language, one that
|
121 |
+
is widely used among developers working in that language.
|
122 |
+
|
123 |
+
The "System Libraries" of an executable work include anything, other
|
124 |
+
than the work as a whole, that (a) is included in the normal form of
|
125 |
+
packaging a Major Component, but which is not part of that Major
|
126 |
+
Component, and (b) serves only to enable use of the work with that
|
127 |
+
Major Component, or to implement a Standard Interface for which an
|
128 |
+
implementation is available to the public in source code form. A
|
129 |
+
"Major Component", in this context, means a major essential component
|
130 |
+
(kernel, window system, and so on) of the specific operating system
|
131 |
+
(if any) on which the executable work runs, or a compiler used to
|
132 |
+
produce the work, or an object code interpreter used to run it.
|
133 |
+
|
134 |
+
The "Corresponding Source" for a work in object code form means all
|
135 |
+
the source code needed to generate, install, and (for an executable
|
136 |
+
work) run the object code and to modify the work, including scripts to
|
137 |
+
control those activities. However, it does not include the work's
|
138 |
+
System Libraries, or general-purpose tools or generally available free
|
139 |
+
programs which are used unmodified in performing those activities but
|
140 |
+
which are not part of the work. For example, Corresponding Source
|
141 |
+
includes interface definition files associated with source files for
|
142 |
+
the work, and the source code for shared libraries and dynamically
|
143 |
+
linked subprograms that the work is specifically designed to require,
|
144 |
+
such as by intimate data communication or control flow between those
|
145 |
+
subprograms and other parts of the work.
|
146 |
+
|
147 |
+
The Corresponding Source need not include anything that users
|
148 |
+
can regenerate automatically from other parts of the Corresponding
|
149 |
+
Source.
|
150 |
+
|
151 |
+
The Corresponding Source for a work in source code form is that
|
152 |
+
same work.
|
153 |
+
|
154 |
+
2. Basic Permissions.
|
155 |
+
|
156 |
+
All rights granted under this License are granted for the term of
|
157 |
+
copyright on the Program, and are irrevocable provided the stated
|
158 |
+
conditions are met. This License explicitly affirms your unlimited
|
159 |
+
permission to run the unmodified Program. The output from running a
|
160 |
+
covered work is covered by this License only if the output, given its
|
161 |
+
content, constitutes a covered work. This License acknowledges your
|
162 |
+
rights of fair use or other equivalent, as provided by copyright law.
|
163 |
+
|
164 |
+
You may make, run and propagate covered works that you do not
|
165 |
+
convey, without conditions so long as your license otherwise remains
|
166 |
+
in force. You may convey covered works to others for the sole purpose
|
167 |
+
of having them make modifications exclusively for you, or provide you
|
168 |
+
with facilities for running those works, provided that you comply with
|
169 |
+
the terms of this License in conveying all material for which you do
|
170 |
+
not control copyright. Those thus making or running the covered works
|
171 |
+
for you must do so exclusively on your behalf, under your direction
|
172 |
+
and control, on terms that prohibit them from making any copies of
|
173 |
+
your copyrighted material outside their relationship with you.
|
174 |
+
|
175 |
+
Conveying under any other circumstances is permitted solely under
|
176 |
+
the conditions stated below. Sublicensing is not allowed; section 10
|
177 |
+
makes it unnecessary.
|
178 |
+
|
179 |
+
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
180 |
+
|
181 |
+
No covered work shall be deemed part of an effective technological
|
182 |
+
measure under any applicable law fulfilling obligations under article
|
183 |
+
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
184 |
+
similar laws prohibiting or restricting circumvention of such
|
185 |
+
measures.
|
186 |
+
|
187 |
+
When you convey a covered work, you waive any legal power to forbid
|
188 |
+
circumvention of technological measures to the extent such circumvention
|
189 |
+
is effected by exercising rights under this License with respect to
|
190 |
+
the covered work, and you disclaim any intention to limit operation or
|
191 |
+
modification of the work as a means of enforcing, against the work's
|
192 |
+
users, your or third parties' legal rights to forbid circumvention of
|
193 |
+
technological measures.
|
194 |
+
|
195 |
+
4. Conveying Verbatim Copies.
|
196 |
+
|
197 |
+
You may convey verbatim copies of the Program's source code as you
|
198 |
+
receive it, in any medium, provided that you conspicuously and
|
199 |
+
appropriately publish on each copy an appropriate copyright notice;
|
200 |
+
keep intact all notices stating that this License and any
|
201 |
+
non-permissive terms added in accord with section 7 apply to the code;
|
202 |
+
keep intact all notices of the absence of any warranty; and give all
|
203 |
+
recipients a copy of this License along with the Program.
|
204 |
+
|
205 |
+
You may charge any price or no price for each copy that you convey,
|
206 |
+
and you may offer support or warranty protection for a fee.
|
207 |
+
|
208 |
+
5. Conveying Modified Source Versions.
|
209 |
+
|
210 |
+
You may convey a work based on the Program, or the modifications to
|
211 |
+
produce it from the Program, in the form of source code under the
|
212 |
+
terms of section 4, provided that you also meet all of these conditions:
|
213 |
+
|
214 |
+
a) The work must carry prominent notices stating that you modified
|
215 |
+
it, and giving a relevant date.
|
216 |
+
|
217 |
+
b) The work must carry prominent notices stating that it is
|
218 |
+
released under this License and any conditions added under section
|
219 |
+
7. This requirement modifies the requirement in section 4 to
|
220 |
+
"keep intact all notices".
|
221 |
+
|
222 |
+
c) You must license the entire work, as a whole, under this
|
223 |
+
License to anyone who comes into possession of a copy. This
|
224 |
+
License will therefore apply, along with any applicable section 7
|
225 |
+
additional terms, to the whole of the work, and all its parts,
|
226 |
+
regardless of how they are packaged. This License gives no
|
227 |
+
permission to license the work in any other way, but it does not
|
228 |
+
invalidate such permission if you have separately received it.
|
229 |
+
|
230 |
+
d) If the work has interactive user interfaces, each must display
|
231 |
+
Appropriate Legal Notices; however, if the Program has interactive
|
232 |
+
interfaces that do not display Appropriate Legal Notices, your
|
233 |
+
work need not make them do so.
|
234 |
+
|
235 |
+
A compilation of a covered work with other separate and independent
|
236 |
+
works, which are not by their nature extensions of the covered work,
|
237 |
+
and which are not combined with it such as to form a larger program,
|
238 |
+
in or on a volume of a storage or distribution medium, is called an
|
239 |
+
"aggregate" if the compilation and its resulting copyright are not
|
240 |
+
used to limit the access or legal rights of the compilation's users
|
241 |
+
beyond what the individual works permit. Inclusion of a covered work
|
242 |
+
in an aggregate does not cause this License to apply to the other
|
243 |
+
parts of the aggregate.
|
244 |
+
|
245 |
+
6. Conveying Non-Source Forms.
|
246 |
+
|
247 |
+
You may convey a covered work in object code form under the terms
|
248 |
+
of sections 4 and 5, provided that you also convey the
|
249 |
+
machine-readable Corresponding Source under the terms of this License,
|
250 |
+
in one of these ways:
|
251 |
+
|
252 |
+
a) Convey the object code in, or embodied in, a physical product
|
253 |
+
(including a physical distribution medium), accompanied by the
|
254 |
+
Corresponding Source fixed on a durable physical medium
|
255 |
+
customarily used for software interchange.
|
256 |
+
|
257 |
+
b) Convey the object code in, or embodied in, a physical product
|
258 |
+
(including a physical distribution medium), accompanied by a
|
259 |
+
written offer, valid for at least three years and valid for as
|
260 |
+
long as you offer spare parts or customer support for that product
|
261 |
+
model, to give anyone who possesses the object code either (1) a
|
262 |
+
copy of the Corresponding Source for all the software in the
|
263 |
+
product that is covered by this License, on a durable physical
|
264 |
+
medium customarily used for software interchange, for a price no
|
265 |
+
more than your reasonable cost of physically performing this
|
266 |
+
conveying of source, or (2) access to copy the
|
267 |
+
Corresponding Source from a network server at no charge.
|
268 |
+
|
269 |
+
c) Convey individual copies of the object code with a copy of the
|
270 |
+
written offer to provide the Corresponding Source. This
|
271 |
+
alternative is allowed only occasionally and noncommercially, and
|
272 |
+
only if you received the object code with such an offer, in accord
|
273 |
+
with subsection 6b.
|
274 |
+
|
275 |
+
d) Convey the object code by offering access from a designated
|
276 |
+
place (gratis or for a charge), and offer equivalent access to the
|
277 |
+
Corresponding Source in the same way through the same place at no
|
278 |
+
further charge. You need not require recipients to copy the
|
279 |
+
Corresponding Source along with the object code. If the place to
|
280 |
+
copy the object code is a network server, the Corresponding Source
|
281 |
+
may be on a different server (operated by you or a third party)
|
282 |
+
that supports equivalent copying facilities, provided you maintain
|
283 |
+
clear directions next to the object code saying where to find the
|
284 |
+
Corresponding Source. Regardless of what server hosts the
|
285 |
+
Corresponding Source, you remain obligated to ensure that it is
|
286 |
+
available for as long as needed to satisfy these requirements.
|
287 |
+
|
288 |
+
e) Convey the object code using peer-to-peer transmission, provided
|
289 |
+
you inform other peers where the object code and Corresponding
|
290 |
+
Source of the work are being offered to the general public at no
|
291 |
+
charge under subsection 6d.
|
292 |
+
|
293 |
+
A separable portion of the object code, whose source code is excluded
|
294 |
+
from the Corresponding Source as a System Library, need not be
|
295 |
+
included in conveying the object code work.
|
296 |
+
|
297 |
+
A "User Product" is either (1) a "consumer product", which means any
|
298 |
+
tangible personal property which is normally used for personal, family,
|
299 |
+
or household purposes, or (2) anything designed or sold for incorporation
|
300 |
+
into a dwelling. In determining whether a product is a consumer product,
|
301 |
+
doubtful cases shall be resolved in favor of coverage. For a particular
|
302 |
+
product received by a particular user, "normally used" refers to a
|
303 |
+
typical or common use of that class of product, regardless of the status
|
304 |
+
of the particular user or of the way in which the particular user
|
305 |
+
actually uses, or expects or is expected to use, the product. A product
|
306 |
+
is a consumer product regardless of whether the product has substantial
|
307 |
+
commercial, industrial or non-consumer uses, unless such uses represent
|
308 |
+
the only significant mode of use of the product.
|
309 |
+
|
310 |
+
"Installation Information" for a User Product means any methods,
|
311 |
+
procedures, authorization keys, or other information required to install
|
312 |
+
and execute modified versions of a covered work in that User Product from
|
313 |
+
a modified version of its Corresponding Source. The information must
|
314 |
+
suffice to ensure that the continued functioning of the modified object
|
315 |
+
code is in no case prevented or interfered with solely because
|
316 |
+
modification has been made.
|
317 |
+
|
318 |
+
If you convey an object code work under this section in, or with, or
|
319 |
+
specifically for use in, a User Product, and the conveying occurs as
|
320 |
+
part of a transaction in which the right of possession and use of the
|
321 |
+
User Product is transferred to the recipient in perpetuity or for a
|
322 |
+
fixed term (regardless of how the transaction is characterized), the
|
323 |
+
Corresponding Source conveyed under this section must be accompanied
|
324 |
+
by the Installation Information. But this requirement does not apply
|
325 |
+
if neither you nor any third party retains the ability to install
|
326 |
+
modified object code on the User Product (for example, the work has
|
327 |
+
been installed in ROM).
|
328 |
+
|
329 |
+
The requirement to provide Installation Information does not include a
|
330 |
+
requirement to continue to provide support service, warranty, or updates
|
331 |
+
for a work that has been modified or installed by the recipient, or for
|
332 |
+
the User Product in which it has been modified or installed. Access to a
|
333 |
+
network may be denied when the modification itself materially and
|
334 |
+
adversely affects the operation of the network or violates the rules and
|
335 |
+
protocols for communication across the network.
|
336 |
+
|
337 |
+
Corresponding Source conveyed, and Installation Information provided,
|
338 |
+
in accord with this section must be in a format that is publicly
|
339 |
+
documented (and with an implementation available to the public in
|
340 |
+
source code form), and must require no special password or key for
|
341 |
+
unpacking, reading or copying.
|
342 |
+
|
343 |
+
7. Additional Terms.
|
344 |
+
|
345 |
+
"Additional permissions" are terms that supplement the terms of this
|
346 |
+
License by making exceptions from one or more of its conditions.
|
347 |
+
Additional permissions that are applicable to the entire Program shall
|
348 |
+
be treated as though they were included in this License, to the extent
|
349 |
+
that they are valid under applicable law. If additional permissions
|
350 |
+
apply only to part of the Program, that part may be used separately
|
351 |
+
under those permissions, but the entire Program remains governed by
|
352 |
+
this License without regard to the additional permissions.
|
353 |
+
|
354 |
+
When you convey a copy of a covered work, you may at your option
|
355 |
+
remove any additional permissions from that copy, or from any part of
|
356 |
+
it. (Additional permissions may be written to require their own
|
357 |
+
removal in certain cases when you modify the work.) You may place
|
358 |
+
additional permissions on material, added by you to a covered work,
|
359 |
+
for which you have or can give appropriate copyright permission.
|
360 |
+
|
361 |
+
Notwithstanding any other provision of this License, for material you
|
362 |
+
add to a covered work, you may (if authorized by the copyright holders of
|
363 |
+
that material) supplement the terms of this License with terms:
|
364 |
+
|
365 |
+
a) Disclaiming warranty or limiting liability differently from the
|
366 |
+
terms of sections 15 and 16 of this License; or
|
367 |
+
|
368 |
+
b) Requiring preservation of specified reasonable legal notices or
|
369 |
+
author attributions in that material or in the Appropriate Legal
|
370 |
+
Notices displayed by works containing it; or
|
371 |
+
|
372 |
+
c) Prohibiting misrepresentation of the origin of that material, or
|
373 |
+
requiring that modified versions of such material be marked in
|
374 |
+
reasonable ways as different from the original version; or
|
375 |
+
|
376 |
+
d) Limiting the use for publicity purposes of names of licensors or
|
377 |
+
authors of the material; or
|
378 |
+
|
379 |
+
e) Declining to grant rights under trademark law for use of some
|
380 |
+
trade names, trademarks, or service marks; or
|
381 |
+
|
382 |
+
f) Requiring indemnification of licensors and authors of that
|
383 |
+
material by anyone who conveys the material (or modified versions of
|
384 |
+
it) with contractual assumptions of liability to the recipient, for
|
385 |
+
any liability that these contractual assumptions directly impose on
|
386 |
+
those licensors and authors.
|
387 |
+
|
388 |
+
All other non-permissive additional terms are considered "further
|
389 |
+
restrictions" within the meaning of section 10. If the Program as you
|
390 |
+
received it, or any part of it, contains a notice stating that it is
|
391 |
+
governed by this License along with a term that is a further
|
392 |
+
restriction, you may remove that term. If a license document contains
|
393 |
+
a further restriction but permits relicensing or conveying under this
|
394 |
+
License, you may add to a covered work material governed by the terms
|
395 |
+
of that license document, provided that the further restriction does
|
396 |
+
not survive such relicensing or conveying.
|
397 |
+
|
398 |
+
If you add terms to a covered work in accord with this section, you
|
399 |
+
must place, in the relevant source files, a statement of the
|
400 |
+
additional terms that apply to those files, or a notice indicating
|
401 |
+
where to find the applicable terms.
|
402 |
+
|
403 |
+
Additional terms, permissive or non-permissive, may be stated in the
|
404 |
+
form of a separately written license, or stated as exceptions;
|
405 |
+
the above requirements apply either way.
|
406 |
+
|
407 |
+
8. Termination.
|
408 |
+
|
409 |
+
You may not propagate or modify a covered work except as expressly
|
410 |
+
provided under this License. Any attempt otherwise to propagate or
|
411 |
+
modify it is void, and will automatically terminate your rights under
|
412 |
+
this License (including any patent licenses granted under the third
|
413 |
+
paragraph of section 11).
|
414 |
+
|
415 |
+
However, if you cease all violation of this License, then your
|
416 |
+
license from a particular copyright holder is reinstated (a)
|
417 |
+
provisionally, unless and until the copyright holder explicitly and
|
418 |
+
finally terminates your license, and (b) permanently, if the copyright
|
419 |
+
holder fails to notify you of the violation by some reasonable means
|
420 |
+
prior to 60 days after the cessation.
|
421 |
+
|
422 |
+
Moreover, your license from a particular copyright holder is
|
423 |
+
reinstated permanently if the copyright holder notifies you of the
|
424 |
+
violation by some reasonable means, this is the first time you have
|
425 |
+
received notice of violation of this License (for any work) from that
|
426 |
+
copyright holder, and you cure the violation prior to 30 days after
|
427 |
+
your receipt of the notice.
|
428 |
+
|
429 |
+
Termination of your rights under this section does not terminate the
|
430 |
+
licenses of parties who have received copies or rights from you under
|
431 |
+
this License. If your rights have been terminated and not permanently
|
432 |
+
reinstated, you do not qualify to receive new licenses for the same
|
433 |
+
material under section 10.
|
434 |
+
|
435 |
+
9. Acceptance Not Required for Having Copies.
|
436 |
+
|
437 |
+
You are not required to accept this License in order to receive or
|
438 |
+
run a copy of the Program. Ancillary propagation of a covered work
|
439 |
+
occurring solely as a consequence of using peer-to-peer transmission
|
440 |
+
to receive a copy likewise does not require acceptance. However,
|
441 |
+
nothing other than this License grants you permission to propagate or
|
442 |
+
modify any covered work. These actions infringe copyright if you do
|
443 |
+
not accept this License. Therefore, by modifying or propagating a
|
444 |
+
covered work, you indicate your acceptance of this License to do so.
|
445 |
+
|
446 |
+
10. Automatic Licensing of Downstream Recipients.
|
447 |
+
|
448 |
+
Each time you convey a covered work, the recipient automatically
|
449 |
+
receives a license from the original licensors, to run, modify and
|
450 |
+
propagate that work, subject to this License. You are not responsible
|
451 |
+
for enforcing compliance by third parties with this License.
|
452 |
+
|
453 |
+
An "entity transaction" is a transaction transferring control of an
|
454 |
+
organization, or substantially all assets of one, or subdividing an
|
455 |
+
organization, or merging organizations. If propagation of a covered
|
456 |
+
work results from an entity transaction, each party to that
|
457 |
+
transaction who receives a copy of the work also receives whatever
|
458 |
+
licenses to the work the party's predecessor in interest had or could
|
459 |
+
give under the previous paragraph, plus a right to possession of the
|
460 |
+
Corresponding Source of the work from the predecessor in interest, if
|
461 |
+
the predecessor has it or can get it with reasonable efforts.
|
462 |
+
|
463 |
+
You may not impose any further restrictions on the exercise of the
|
464 |
+
rights granted or affirmed under this License. For example, you may
|
465 |
+
not impose a license fee, royalty, or other charge for exercise of
|
466 |
+
rights granted under this License, and you may not initiate litigation
|
467 |
+
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
468 |
+
any patent claim is infringed by making, using, selling, offering for
|
469 |
+
sale, or importing the Program or any portion of it.
|
470 |
+
|
471 |
+
11. Patents.
|
472 |
+
|
473 |
+
A "contributor" is a copyright holder who authorizes use under this
|
474 |
+
License of the Program or a work on which the Program is based. The
|
475 |
+
work thus licensed is called the contributor's "contributor version".
|
476 |
+
|
477 |
+
A contributor's "essential patent claims" are all patent claims
|
478 |
+
owned or controlled by the contributor, whether already acquired or
|
479 |
+
hereafter acquired, that would be infringed by some manner, permitted
|
480 |
+
by this License, of making, using, or selling its contributor version,
|
481 |
+
but do not include claims that would be infringed only as a
|
482 |
+
consequence of further modification of the contributor version. For
|
483 |
+
purposes of this definition, "control" includes the right to grant
|
484 |
+
patent sublicenses in a manner consistent with the requirements of
|
485 |
+
this License.
|
486 |
+
|
487 |
+
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
488 |
+
patent license under the contributor's essential patent claims, to
|
489 |
+
make, use, sell, offer for sale, import and otherwise run, modify and
|
490 |
+
propagate the contents of its contributor version.
|
491 |
+
|
492 |
+
In the following three paragraphs, a "patent license" is any express
|
493 |
+
agreement or commitment, however denominated, not to enforce a patent
|
494 |
+
(such as an express permission to practice a patent or covenant not to
|
495 |
+
sue for patent infringement). To "grant" such a patent license to a
|
496 |
+
party means to make such an agreement or commitment not to enforce a
|
497 |
+
patent against the party.
|
498 |
+
|
499 |
+
If you convey a covered work, knowingly relying on a patent license,
|
500 |
+
and the Corresponding Source of the work is not available for anyone
|
501 |
+
to copy, free of charge and under the terms of this License, through a
|
502 |
+
publicly available network server or other readily accessible means,
|
503 |
+
then you must either (1) cause the Corresponding Source to be so
|
504 |
+
available, or (2) arrange to deprive yourself of the benefit of the
|
505 |
+
patent license for this particular work, or (3) arrange, in a manner
|
506 |
+
consistent with the requirements of this License, to extend the patent
|
507 |
+
license to downstream recipients. "Knowingly relying" means you have
|
508 |
+
actual knowledge that, but for the patent license, your conveying the
|
509 |
+
covered work in a country, or your recipient's use of the covered work
|
510 |
+
in a country, would infringe one or more identifiable patents in that
|
511 |
+
country that you have reason to believe are valid.
|
512 |
+
|
513 |
+
If, pursuant to or in connection with a single transaction or
|
514 |
+
arrangement, you convey, or propagate by procuring conveyance of, a
|
515 |
+
covered work, and grant a patent license to some of the parties
|
516 |
+
receiving the covered work authorizing them to use, propagate, modify
|
517 |
+
or convey a specific copy of the covered work, then the patent license
|
518 |
+
you grant is automatically extended to all recipients of the covered
|
519 |
+
work and works based on it.
|
520 |
+
|
521 |
+
A patent license is "discriminatory" if it does not include within
|
522 |
+
the scope of its coverage, prohibits the exercise of, or is
|
523 |
+
conditioned on the non-exercise of one or more of the rights that are
|
524 |
+
specifically granted under this License. You may not convey a covered
|
525 |
+
work if you are a party to an arrangement with a third party that is
|
526 |
+
in the business of distributing software, under which you make payment
|
527 |
+
to the third party based on the extent of your activity of conveying
|
528 |
+
the work, and under which the third party grants, to any of the
|
529 |
+
parties who would receive the covered work from you, a discriminatory
|
530 |
+
patent license (a) in connection with copies of the covered work
|
531 |
+
conveyed by you (or copies made from those copies), or (b) primarily
|
532 |
+
for and in connection with specific products or compilations that
|
533 |
+
contain the covered work, unless you entered into that arrangement,
|
534 |
+
or that patent license was granted, prior to 28 March 2007.
|
535 |
+
|
536 |
+
Nothing in this License shall be construed as excluding or limiting
|
537 |
+
any implied license or other defenses to infringement that may
|
538 |
+
otherwise be available to you under applicable patent law.
|
539 |
+
|
540 |
+
12. No Surrender of Others' Freedom.
|
541 |
+
|
542 |
+
If conditions are imposed on you (whether by court order, agreement or
|
543 |
+
otherwise) that contradict the conditions of this License, they do not
|
544 |
+
excuse you from the conditions of this License. If you cannot convey a
|
545 |
+
covered work so as to satisfy simultaneously your obligations under this
|
546 |
+
License and any other pertinent obligations, then as a consequence you may
|
547 |
+
not convey it at all. For example, if you agree to terms that obligate you
|
548 |
+
to collect a royalty for further conveying from those to whom you convey
|
549 |
+
the Program, the only way you could satisfy both those terms and this
|
550 |
+
License would be to refrain entirely from conveying the Program.
|
551 |
+
|
552 |
+
13. Use with the GNU Affero General Public License.
|
553 |
+
|
554 |
+
Notwithstanding any other provision of this License, you have
|
555 |
+
permission to link or combine any covered work with a work licensed
|
556 |
+
under version 3 of the GNU Affero General Public License into a single
|
557 |
+
combined work, and to convey the resulting work. The terms of this
|
558 |
+
License will continue to apply to the part which is the covered work,
|
559 |
+
but the special requirements of the GNU Affero General Public License,
|
560 |
+
section 13, concerning interaction through a network will apply to the
|
561 |
+
combination as such.
|
562 |
+
|
563 |
+
14. Revised Versions of this License.
|
564 |
+
|
565 |
+
The Free Software Foundation may publish revised and/or new versions of
|
566 |
+
the GNU General Public License from time to time. Such new versions will
|
567 |
+
be similar in spirit to the present version, but may differ in detail to
|
568 |
+
address new problems or concerns.
|
569 |
+
|
570 |
+
Each version is given a distinguishing version number. If the
|
571 |
+
Program specifies that a certain numbered version of the GNU General
|
572 |
+
Public License "or any later version" applies to it, you have the
|
573 |
+
option of following the terms and conditions either of that numbered
|
574 |
+
version or of any later version published by the Free Software
|
575 |
+
Foundation. If the Program does not specify a version number of the
|
576 |
+
GNU General Public License, you may choose any version ever published
|
577 |
+
by the Free Software Foundation.
|
578 |
+
|
579 |
+
If the Program specifies that a proxy can decide which future
|
580 |
+
versions of the GNU General Public License can be used, that proxy's
|
581 |
+
public statement of acceptance of a version permanently authorizes you
|
582 |
+
to choose that version for the Program.
|
583 |
+
|
584 |
+
Later license versions may give you additional or different
|
585 |
+
permissions. However, no additional obligations are imposed on any
|
586 |
+
author or copyright holder as a result of your choosing to follow a
|
587 |
+
later version.
|
588 |
+
|
589 |
+
15. Disclaimer of Warranty.
|
590 |
+
|
591 |
+
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
592 |
+
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
593 |
+
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
594 |
+
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
595 |
+
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
596 |
+
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
597 |
+
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
598 |
+
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
599 |
+
|
600 |
+
16. Limitation of Liability.
|
601 |
+
|
602 |
+
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
603 |
+
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
604 |
+
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
605 |
+
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
606 |
+
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
607 |
+
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
608 |
+
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
609 |
+
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
610 |
+
SUCH DAMAGES.
|
611 |
+
|
612 |
+
17. Interpretation of Sections 15 and 16.
|
613 |
+
|
614 |
+
If the disclaimer of warranty and limitation of liability provided
|
615 |
+
above cannot be given local legal effect according to their terms,
|
616 |
+
reviewing courts shall apply local law that most closely approximates
|
617 |
+
an absolute waiver of all civil liability in connection with the
|
618 |
+
Program, unless a warranty or assumption of liability accompanies a
|
619 |
+
copy of the Program in return for a fee.
|
620 |
+
|
621 |
+
END OF TERMS AND CONDITIONS
|
622 |
+
|
623 |
+
How to Apply These Terms to Your New Programs
|
624 |
+
|
625 |
+
If you develop a new program, and you want it to be of the greatest
|
626 |
+
possible use to the public, the best way to achieve this is to make it
|
627 |
+
free software which everyone can redistribute and change under these terms.
|
628 |
+
|
629 |
+
To do so, attach the following notices to the program. It is safest
|
630 |
+
to attach them to the start of each source file to most effectively
|
631 |
+
state the exclusion of warranty; and each file should have at least
|
632 |
+
the "copyright" line and a pointer to where the full notice is found.
|
633 |
+
|
634 |
+
<one line to give the program's name and a brief idea of what it does.>
|
635 |
+
Copyright (C) <year> <name of author>
|
636 |
+
|
637 |
+
This program is free software: you can redistribute it and/or modify
|
638 |
+
it under the terms of the GNU General Public License as published by
|

+
the Free Software Foundation, either version 3 of the License, or
|
640 |
+
(at your option) any later version.
|
641 |
+
|
642 |
+
This program is distributed in the hope that it will be useful,
|
643 |
+
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
644 |
+
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
645 |
+
GNU General Public License for more details.
|
646 |
+
|
647 |
+
You should have received a copy of the GNU General Public License
|
648 |
+
along with this program. If not, see <http://www.gnu.org/licenses/>.
|
649 |
+
|
650 |
+
Also add information on how to contact you by electronic and paper mail.
|
651 |
+
|
652 |
+
If the program does terminal interaction, make it output a short
|
653 |
+
notice like this when it starts in an interactive mode:
|
654 |
+
|
655 |
+
<program> Copyright (C) <year> <name of author>
|
656 |
+
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
657 |
+
This is free software, and you are welcome to redistribute it
|
658 |
+
under certain conditions; type `show c' for details.
|
659 |
+
|
660 |
+
The hypothetical commands `show w' and `show c' should show the appropriate
|
661 |
+
parts of the General Public License. Of course, your program's commands
|
662 |
+
might be different; for a GUI interface, you would use an "about box".
|
663 |
+
|
664 |
+
You should also get your employer (if you work as a programmer) or school,
|
665 |
+
if any, to sign a "copyright disclaimer" for the program, if necessary.
|
666 |
+

|
668 |
+
|
669 |
+
The GNU General Public License does not permit incorporating your program
|
670 |
+
into proprietary programs. If your program is a subroutine library, you
|
671 |
+
may consider it more useful to permit linking proprietary applications with
|
672 |
+
the library. If this is what you want to do, use the GNU Lesser General
|
673 |
+
Public License instead of this License. But first, please read

ffmpeg-bitstream-filters - FFmpeg bitstream filters
|

|
6 |
+
DESCRIPTION
|
7 |
+
This document describes the bitstream filters provided by the
|
8 |
+
libavcodec library.
|
9 |
+
|
10 |
+
A bitstream filter operates on the encoded stream data, and performs
|
11 |
+
bitstream level modifications without performing decoding.
|
12 |
+
|
13 |
+
BITSTREAM FILTERS
|
14 |
+
When you configure your FFmpeg build, all the supported bitstream
|
15 |
+
filters are enabled by default. You can list all available ones using
|
16 |
+
the configure option "--list-bsfs".
|
17 |
+
|
18 |
+
You can disable all the bitstream filters using the configure option
|
19 |
+
"--disable-bsfs", and selectively enable any bitstream filter using the
|
20 |
+
option "--enable-bsf=BSF", or you can disable a particular bitstream
|
21 |
+
filter using the option "--disable-bsf=BSF".
|
22 |
+
|
23 |
+
The option "-bsfs" of the ff* tools will display the list of all the
|
24 |
+
supported bitstream filters included in your build.
|
25 |
+
|
26 |
+
The ff* tools have a -bsf option applied per stream, taking a comma-
|
27 |
+
separated list of filters, whose parameters follow the filter name
|
28 |
+
after a '='.
|
29 |
+
|
30 |
+
ffmpeg -i INPUT -c:v copy -bsf:v filter1[=opt1=str1:opt2=str2][,filter2] OUTPUT
|
31 |
+
|
32 |
+
Below is a description of the currently available bitstream filters,
|
33 |
+
with their parameters, if any.
|
34 |
+
|
35 |
+
aac_adtstoasc
|
36 |
+
Convert MPEG-2/4 AAC ADTS to an MPEG-4 Audio Specific Configuration
|
37 |
+
bitstream.
|
38 |
+
|
39 |
+
This filter creates an MPEG-4 AudioSpecificConfig from an MPEG-2/4 ADTS
|
40 |
+
header and removes the ADTS header.
|
41 |
+
|
42 |
+
This filter is required for example when copying an AAC stream from a
|
43 |
+
raw ADTS AAC or an MPEG-TS container to MP4A-LATM, to an FLV file, or
|
44 |
+
to MOV/MP4 files and related formats such as 3GP or M4A. Please note
|
45 |
+
that it is auto-inserted for MP4A-LATM and MOV/MP4 and related formats.
|

+
this cannot be set for streams using BT.709 primaries, sRGB
|
69 |
+
transfer characteristic and identity (RGB) matrix coefficients).
|
70 |
+
|

+
pc Full range.
|
74 |
+
|
75 |
+
chroma_sample_position
|
76 |
+
Set the chroma sample location in the stream (see AV1 section
|
77 |
+
6.4.2). This can only be set for 4:2:0 streams.
|
78 |
+
|
79 |
+

+
tick_rate
|
86 |
+
Set the tick rate (time_scale / num_units_in_display_tick) in the
|
87 |
+
timing info in the sequence header.
|
88 |
+
|
89 |
+
num_ticks_per_picture
|
90 |
+
Set the number of ticks in each picture, to indicate that the
|
91 |
+
stream has a fixed framerate. Ignored if tick_rate is not also
|
92 |
+
set.
|
93 |
+
|
94 |
+
delete_padding
|
95 |
+
Deletes Padding OBUs.
|
96 |
+
|
97 |
+
chomp
|
98 |
+
Remove zero padding at the end of a packet.
|
99 |
+
|
100 |
+
dca_core
|
101 |
+
Extract the core from a DCA/DTS stream, dropping extensions such as
|
102 |
+
DTS-HD.
|
103 |
+
|
104 |
+
dump_extra
|
105 |
+
Add extradata to the beginning of the filtered packets except when said
|
106 |
+
packets already exactly begin with the extradata that is intended to be
|
107 |
+
added.
|
108 |
+
|
109 |
+
freq
|
110 |
+
The additional argument specifies which packets should be filtered.
|
111 |
+
It accepts the values:
|
112 |
+
|
113 |
+
k
|
114 |
+
keyframe
|
115 |
+
add extradata to all key packets
|
116 |
+
|
117 |
+
e
|
118 |
+
all add extradata to all packets
|
119 |
+
|
120 |
+
If not specified it is assumed k.
|
121 |
+
|
122 |
+
For example the following ffmpeg command forces a global header (thus
|
123 |
+
disabling individual packet headers) in the H.264 packets generated by
|
124 |
+
the "libx264" encoder, but corrects them by adding the header stored in
|
125 |
+
extradata to the key packets:
|
126 |
+
|
127 |
+
ffmpeg -i INPUT -map 0 -flags:v +global_header -c:v libx264 -bsf:v dump_extra out.ts
|
128 |
+
|
129 |
+
dv_error_marker
|
130 |
+
Blocks in DV which are marked as damaged are replaced by blocks of the
|
131 |
+
specified color.
|
132 |
+
|
133 |
+
color
|
134 |
+
The color to replace damaged blocks by
|
135 |
+
|
136 |
+
sta A 16 bit mask which specifies which of the 16 possible error status
|
137 |
+
values are to be replaced by colored blocks. 0xFFFE is the default
|
138 |
+
which replaces all non 0 error status values.
|

+
|
140 |
+

156 |
+
<http://web.archive.org/web/20060927044735/http://www.smpte.org/smpte_store/standards/pdf/s314m.pdf>
|
157 |
+
|
158 |
+
eac3_core
|
159 |
+
Extract the core from a E-AC-3 stream, dropping extra channels.
|
160 |
+
|
161 |
+
extract_extradata
|
162 |
+
Extract the in-band extradata.
|
163 |
+
|
164 |
+
Certain codecs allow the long-term headers (e.g. MPEG-2 sequence
|
165 |
+
headers, or H.264/HEVC (VPS/)SPS/PPS) to be transmitted either "in-
|
166 |
+
band" (i.e. as a part of the bitstream containing the coded frames) or
|
167 |
+
"out of band" (e.g. on the container level). This latter form is called
|
168 |
+
"extradata" in FFmpeg terminology.
|
169 |
+
|
170 |
+
This bitstream filter detects the in-band headers and makes them
|
171 |
+
available as extradata.
|
172 |
+
|
173 |
+
remove
|
174 |
+
When this option is enabled, the long-term headers are removed from
|
175 |
+
the bitstream after extraction.
|
176 |
+
|
177 |
+
filter_units
|
178 |
+
Remove units with types in or not in a given set from the stream.
|
179 |
+
|
180 |
+
pass_types
|
181 |
+
List of unit types or ranges of unit types to pass through while
|
182 |
+
removing all others. This is specified as a '|'-separated list of
|
183 |
+
unit type values or ranges of values with '-'.
|
184 |
+
|
185 |
+
remove_types
|
186 |
+
Identical to pass_types, except the units in the given set removed
|
187 |
+
and all others passed through.
|
188 |
+
|
189 |
+
Extradata is unchanged by this transformation, but note that if the
|
190 |
+
stream contains inline parameter sets then the output may be unusable
|
191 |
+
if they are removed.
|
192 |
+
|
193 |
+
For example, to remove all non-VCL NAL units from an H.264 stream:
|
194 |
+
|
195 |
+
ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=pass_types=1-5' OUTPUT
|
196 |
+
|
197 |
+
To remove all AUDs, SEI and filler from an H.265 stream:
|
198 |
+
|
199 |
+
ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=remove_types=35|38-40' OUTPUT
|
200 |
+
|
201 |
+
hapqa_extract
|
202 |
+
Extract Rgb or Alpha part of an HAPQA file, without recompression, in
|
203 |
+
order to create an HAPQ or an HAPAlphaOnly file.
|
204 |
+
|
205 |
+
texture
|
206 |
+
Specifies the texture to keep.
|
207 |
+
|
208 |
+

212 |
+
|
213 |
+
ffmpeg -i hapqa_inputfile.mov -c copy -bsf:v hapqa_extract=texture=color -tag:v HapY -metadata:s:v:0 encoder="HAPQ" hapq_file.mov
|
214 |
+
|
215 |
+
Convert HAPQA to HAPAlphaOnly
|
216 |
+
|
217 |
+
ffmpeg -i hapqa_inputfile.mov -c copy -bsf:v hapqa_extract=texture=alpha -tag:v HapA -metadata:s:v:0 encoder="HAPAlpha Only" hapalphaonly_file.mov

aud Insert or remove AUD NAL units in all access units of the stream.
|
223 |
+
|
224 |
+
pass
|
225 |
+
insert
|
226 |
+
remove
|
227 |
+
|
228 |
+
Default is pass.
|
229 |
+
|
230 |
+
sample_aspect_ratio
|
231 |
+
Set the sample aspect ratio of the stream in the VUI parameters.
|
232 |
+
See H.264 table E-1.
|
233 |
+
|
234 |
+
overscan_appropriate_flag
|
235 |
+
Set whether the stream is suitable for display using overscan or
|
236 |
+
not (see H.264 section E.2.1).
|
237 |
+
|
238 |
+
video_format
|
239 |
+
video_full_range_flag
|
240 |
+
Set the video format in the stream (see H.264 section E.2.1 and
|
241 |
+
table E-2).
|
242 |
+
|
243 |
+
colour_primaries
|
244 |
+
transfer_characteristics
|
245 |
+
matrix_coefficients
|
246 |
+
Set the colour description in the stream (see H.264 section E.2.1
|
247 |
+
and tables E-3, E-4 and E-5).
|
248 |
+
|
249 |
+
chroma_sample_loc_type
|
250 |
+
Set the chroma sample location in the stream (see H.264 section
|
251 |
+
E.2.1 and figure E-1).
|
252 |
+
|
253 |
+
tick_rate
|
254 |
+
Set the tick rate (time_scale / num_units_in_tick) in the VUI
|
255 |
+
parameters. This is the smallest time unit representable in the
|
256 |
+
stream, and in many cases represents the field rate of the stream
|
257 |
+
(double the frame rate).
|
258 |
+
|
259 |
+
fixed_frame_rate_flag
|
260 |
+
Set whether the stream has fixed framerate - typically this
|
261 |
+
indicates that the framerate is exactly half the tick rate, but the
|
262 |
+
exact meaning is dependent on interlacing and the picture structure
|
263 |
+
(see H.264 section E.2.1 and table E-6).
|
264 |
+
|
265 |
+
zero_new_constraint_set_flags
|
266 |
+
Zero constraint_set4_flag and constraint_set5_flag in the SPS.
|
267 |
+
These bits were reserved in a previous version of the H.264 spec,
|
268 |
+
and thus some hardware decoders require these to be zero. The
|
269 |
+
result of zeroing this is still a valid bitstream.
|
270 |
+
|
271 |
+
crop_left
|
272 |
+
crop_right
|
273 |
+
crop_top
|
274 |
+
crop_bottom
|
275 |
+
Set the frame cropping offsets in the SPS. These values will
|
276 |
+
replace the current ones if the stream is already cropped.
|
277 |
+
|
278 |
+
These fields are set in pixels. Note that some sizes may not be
|
279 |
+
representable if the chroma is subsampled or the stream is
|
280 |
+
interlaced (see H.264 section 7.4.2.1.1).
|
281 |
+
|
282 |
+
sei_user_data
|
283 |
+
Insert a string as SEI unregistered user data. The argument must
|
284 |
+
be of the form UUID+string, where the UUID is as hex digits
|
285 |
+
possibly separated by hyphens, and the string can be anything.
|
286 |
+
|
287 |
+
For example, 086f3693-b7b3-4f2c-9653-21492feee5b8+hello will insert
|
288 |
+
the string ``hello'' associated with the given UUID.
|
289 |
+
|
290 |
+
delete_filler
|
291 |
+
Deletes both filler NAL units and filler SEI messages.
|
292 |
+
|
293 |
+
display_orientation
|
294 |
+
Insert, extract or remove Display orientation SEI messages. See
|
295 |
+
H.264 section D.1.27 and D.2.27 for syntax and semantics.
|

+
extract
|
301 |
+
|
302 |
+
Default is pass.
|
303 |
+
|
304 |
+
Insert mode works in conjunction with "rotate" and "flip" options.
|
305 |
+
Any pre-existing Display orientation messages will be removed in
|
306 |
+
insert or remove mode. Extract mode attaches the display matrix to
|
307 |
+
the packet as side data.
|
308 |
+
|
309 |
+
rotate
|
310 |
+
Set rotation in display orientation SEI (anticlockwise angle in
|
311 |
+
degrees). Range is -360 to +360. Default is NaN.
|
312 |
+
|
313 |
+
flip
|
314 |
+
Set flip in display orientation SEI.
|
315 |
+
|
316 |
+
horizontal

318 |
+
|
319 |
+
Default is unset.
|
320 |
+
|
321 |
+
level
|
322 |
+
Set the level in the SPS. Refer to H.264 section A.3 and tables
|
323 |
+
A-1 to A-5.
|
324 |
+
|
325 |
+
The argument must be the name of a level (for example, 4.2), a
|
326 |
+
level_idc value (for example, 42), or the special name auto
|
327 |
+
indicating that the filter should attempt to guess the level from
|
328 |
+
the input stream properties.
|
329 |
+
|
330 |
+
h264_mp4toannexb
|
331 |
+
Convert an H.264 bitstream from length prefixed mode to start code
|
332 |
+
prefixed mode (as defined in the Annex B of the ITU-T H.264
|
333 |
+
specification).
|
334 |
+
|
335 |
+
This is required by some streaming formats, typically the MPEG-2
|
336 |
+
transport stream format (muxer "mpegts").
|
337 |
+
|
338 |
+
For example to remux an MP4 file containing an H.264 stream to mpegts
|
339 |
+
format with ffmpeg, you can use the command:
|
340 |
+
|
341 |
+
ffmpeg -i INPUT.mp4 -codec copy -bsf:v h264_mp4toannexb OUTPUT.ts
|
342 |
+
|
343 |
+
Please note that this filter is auto-inserted for MPEG-TS (muxer
|
344 |
+
"mpegts") and raw H.264 (muxer "h264") output formats.
|
345 |
+
|
346 |
+
h264_redundant_pps
|
347 |
+
This applies a specific fixup to some Blu-ray streams which contain
|
348 |
+
redundant PPSs modifying irrelevant parameters of the stream which
|
349 |
+
confuse other transformations which require correct extradata.
|
350 |
+
|
351 |
+
hevc_metadata
|
352 |
+
Modify metadata embedded in an HEVC stream.
|
353 |
+
|
354 |

aud Insert or remove AUD NAL units in all access units of the stream.
|
355 |
+
|
356 |
+
insert
|
357 |

364 |
+
table E.2).
|
365 |
+
|
366 |
+
colour_primaries
|
367 |
+
transfer_characteristics
|
368 |
+
matrix_coefficients
|
369 |
+
Set the colour description in the stream (see H.265 section E.3.1
|
370 |
+
and tables E.3, E.4 and E.5).
|
371 |
+
|
372 |
+
chroma_sample_loc_type
|
373 |
+
Set the chroma sample location in the stream (see H.265 section
|
374 |
+
E.3.1 and figure E.1).
|
375 |

|
376 |
+
tick_rate
|
377 |
+
Set the tick rate in the VPS and VUI parameters (time_scale /
|
378 |
+
num_units_in_tick). Combined with num_ticks_poc_diff_one, this can
|
379 |
+
set a constant framerate in the stream. Note that it is likely to
|
380 |
+
be overridden by container parameters when the stream is in a
|
381 |
+
container.
|
382 |
+
|
383 |
+
num_ticks_poc_diff_one
|
384 |
+
Set poc_proportional_to_timing_flag in VPS and VUI and use this
|
385 |
+
value to set num_ticks_poc_diff_one_minus1 (see H.265 sections
|
386 |
+
7.4.3.1 and E.3.1). Ignored if tick_rate is not also set.
|
387 |
+
|
388 |
+
crop_left
|
389 |
+
crop_right
|
390 |
+
crop_top
|
391 |
+
crop_bottom
|
392 |
+
Set the conformance window cropping offsets in the SPS. These
|
393 |
+
values will replace the current ones if the stream is already
|
394 |
+
cropped.
|
395 |
+
|
396 |
+
These fields are set in pixels. Note that some sizes may not be
|
397 |
+
representable if the chroma is subsampled (H.265 section
|
398 |
+
7.4.3.2.1).
|
399 |
+
|
400 |
+
level
|
401 |
+
Set the level in the VPS and SPS. See H.265 section A.4 and tables
|
402 |
+
A.6 and A.7.
|
403 |
+
|
404 |
+
The argument must be the name of a level (for example, 5.1), a
|
405 |
+
general_level_idc value (for example, 153 for level 5.1), or the
|
406 |
+
special name auto indicating that the filter should attempt to
|
407 |
+
guess the level from the input stream properties.
|
408 |
+
|
409 |
+
hevc_mp4toannexb
|
410 |
+
Convert an HEVC/H.265 bitstream from length prefixed mode to start code
|
411 |
+
prefixed mode (as defined in the Annex B of the ITU-T H.265
|
412 |
+
specification).
|
413 |
+
|
414 |
+
This is required by some streaming formats, typically the MPEG-2
|
415 |
+
transport stream format (muxer "mpegts").
|
416 |
+
|
417 |
+
For example to remux an MP4 file containing an HEVC stream to mpegts
|
418 |
+
format with ffmpeg, you can use the command:
|
419 |
+
|
420 |
+
ffmpeg -i INPUT.mp4 -codec copy -bsf:v hevc_mp4toannexb OUTPUT.ts
|
421 |
+
|
422 |
+
Please note that this filter is auto-inserted for MPEG-TS (muxer
|
423 |
+
"mpegts") and raw HEVC/H.265 (muxer "h265" or "hevc") output formats.
|
424 |
+
|
425 |
+
imxdump
|
426 |
+
Modifies the bitstream to fit in MOV and to be usable by the Final Cut
|
427 |
+
Pro decoder. This filter only applies to the mpeg2video codec, and is
|
428 |
+
likely not needed for Final Cut Pro 7 and newer with the appropriate
|
429 |
+
-tag:v.
|
430 |
+
|
431 |
+
For example, to remux 30 MB/sec NTSC IMX to MOV:
|
432 |
+
|
433 |
+
ffmpeg -i input.mxf -c copy -bsf:v imxdump -tag:v mx3n output.mov
|
434 |
+
|
435 |
+
mjpeg2jpeg
|
436 |
+
Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
|
437 |
+
|
438 |
+
MJPEG is a video codec wherein each video frame is essentially a JPEG
|
439 |
+
image. The individual frames can be extracted without loss, e.g. by
|
440 |
+
|
441 |
+
ffmpeg -i ../some_mjpeg.avi -c:v copy frames_%d.jpg
|
442 |
+
|
443 |
+
Unfortunately, these chunks are incomplete JPEG images, because they
|
444 |
+
lack the DHT segment required for decoding. Quoting from
|
445 |
+
<http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml>:
|
446 |
+
|
447 |
+
Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
|
448 |
+
commented that "MJPEG, or at least the MJPEG in AVIs having the MJPG
|
449 |
+
fourcc, is restricted JPEG with a fixed -- and *omitted* -- Huffman
|
450 |
+
table. The JPEG must be YCbCr colorspace, it must be 4:2:2, and it must
|
451 |
+
use basic Huffman encoding, not arithmetic or progressive. . . . You
|
452 |
+
can indeed extract the MJPEG frames and decode them with a regular JPEG
|
453 |
+
decoder, but you have to prepend the DHT segment to them, or else the
|
454 |
+
decoder won't have any idea how to decompress the data. The exact table
|
455 |
+
necessary is given in the OpenDML spec."
|
456 |
+
|
457 |
+
This bitstream filter patches the header of frames extracted from an
|
458 |
+
MJPEG stream (carrying the AVI1 header ID and lacking a DHT segment) to
|
459 |
+
produce fully qualified JPEG images.
|
460 |
+
|
461 |
+
ffmpeg -i mjpeg-movie.avi -c:v copy -bsf:v mjpeg2jpeg frame_%d.jpg
|
462 |
+
exiftran -i -9 frame*.jpg
|
463 |
+
ffmpeg -i frame_%d.jpg -c:v copy rotated.avi
|
464 |
+
|
465 |
+
mjpegadump
|
466 |
+
Add an MJPEG A header to the bitstream, to enable decoding by
|
467 |
+
Quicktime.
|
468 |
+
|
469 |
+
mov2textsub
|
470 |
+
Extract a representable text file from MOV subtitles, stripping the
|
471 |
+
metadata header from each subtitle packet.
|
472 |
+
|
473 |
+
See also the text2movsub filter.
|
474 |
+
|
475 |
+
mp3decomp
|
476 |
+
Decompress non-standard compressed MP3 audio headers.
|
477 |
+
|
478 |
+
mpeg2_metadata
|
479 |
+
Modify metadata embedded in an MPEG-2 stream.
|
480 |
+
|
481 |
+
display_aspect_ratio
|
482 |
+
Set the display aspect ratio in the stream.
|
483 |
+
|
484 |
+
The following fixed values are supported:
|
485 |
+
|
486 |
+
4/3
|
487 |
+
16/9
|
488 |
+
221/100
|
489 |
+
|
490 |
+
Any other value will result in square pixels being signalled
|
491 |
+
instead (see H.262 section 6.3.3 and table 6-3).
|
492 |
+
|
493 |
+
frame_rate
|
494 |
+
Set the frame rate in the stream. This is constructed from a table
|
495 |
+
of known values combined with a small multiplier and divisor - if
|
496 |
+
the supplied value is not exactly representable, the nearest
|
497 |
+
representable value will be used instead (see H.262 section 6.3.3
|
498 |
+
and table 6-4).
|
499 |
+
|
500 |
+
video_format
|
501 |
+
Set the video format in the stream (see H.262 section 6.3.6 and
|
502 |
+
table 6-6).
|
503 |
+
|
504 |
+
colour_primaries
|
505 |
+
transfer_characteristics
|
506 |
+
matrix_coefficients
|
507 |
+
Set the colour description in the stream (see H.262 section 6.3.6
|
508 |
+
and tables 6-7, 6-8 and 6-9).
|
509 |
+
|
510 |
+
mpeg4_unpack_bframes
|
511 |
+
Unpack DivX-style packed B-frames.
|
512 |
+
|
513 |
+
DivX-style packed B-frames are not valid MPEG-4 and were only a
|
514 |
+
workaround for the broken Video for Windows subsystem. They use more
|
515 |
+
space, can cause minor AV sync issues, require more CPU power to decode
|
516 |
+
(unless the player has some decoded picture queue to compensate the
|
517 |
+
2,0,2,0 frame per packet style) and cause trouble if copied into a
|
518 |
+
standard container like mp4 or mpeg-ps/ts, because MPEG-4 decoders may
|
519 |
+
not be able to decode them, since they are not valid MPEG-4.
|
520 |
+
|
521 |
+
For example to fix an AVI file containing an MPEG-4 stream with DivX-
|
522 |
+
style packed B-frames using ffmpeg, you can use the command:
|
523 |
+
|
524 |
+
ffmpeg -i INPUT.avi -codec copy -bsf:v mpeg4_unpack_bframes OUTPUT.avi
|
525 |
+
|
526 |
+
noise
|
527 |
+
Damages the contents of packets or simply drops them without damaging
|
528 |
+
the container. Can be used for fuzzing or testing error
|
529 |
+
resilience/concealment.
|
530 |
+
|
531 |
+
Parameters:
|
532 |
+
|
533 |
+
amount
|
534 |
+
Accepts an expression whose evaluation per-packet determines how
|
535 |
+
often bytes in that packet will be modified. A value below 0 will
|
536 |
+
result in a variable frequency. Default is 0 which results in no
|
537 |
+
modification. However, if neither amount nor drop is specified,
|
538 |
+
amount will be set to -1. See below for accepted variables.
|
539 |
+
|
540 |
+
drop
|
541 |
+
Accepts an expression evaluated per-packet whose value determines
|
542 |
+
whether that packet is dropped. Evaluation to a positive value
|
543 |
+
results in the packet being dropped. Evaluation to a negative value
|
544 |
+
results in a variable chance of it being dropped, roughly inverse
|
545 |
+
in proportion to the magnitude of the value. Default is 0 which
|
546 |
+
results in no drops. See below for accepted variables.
|
547 |
+
|
548 |
+
dropamount
|
549 |
+
Accepts a non-negative integer, which assigns a variable chance of
|
550 |
+
it being dropped, roughly inverse in proportion to the value.
|
551 |
+
Default is 0 which results in no drops. This option is kept for
|
552 |
+
backwards compatibility and is equivalent to setting drop to a
|
553 |
+
negative value with the same magnitude i.e. "dropamount=4" is the
|
554 |
+
same as "drop=-4". Ignored if drop is also specified.
|
555 |
+
|
556 |
+
Both "amount" and "drop" accept expressions containing the following
|
557 |
+
variables:
|
558 |
+
|
559 |
+
n The index of the packet, starting from zero.
|
560 |
+
|
561 |
+
tb The timebase for packet timestamps.
|
562 |
+
|
563 |
+
pts Packet presentation timestamp.
|
564 |
+
|
565 |
+
dts Packet decoding timestamp.
|
566 |
+
|
567 |
+
nopts
|
568 |
+
Constant representing AV_NOPTS_VALUE.
|
569 |
+
|
570 |
+
startpts
|
571 |
+
First non-AV_NOPTS_VALUE PTS seen in the stream.
|
572 |
+
|
573 |
+
startdts
|
574 |
+
First non-AV_NOPTS_VALUE DTS seen in the stream.
|
575 |
+
|
576 |
+
duration
|
577 |
+
d Packet duration, in timebase units.
|
578 |
+
|
579 |
+
pos Packet position in input; may be -1 when unknown or not set.
|

+
|
581 |
+
size
|
582 |
+
Packet size, in bytes.
|
583 |
+
|
584 |
+
key Whether packet is marked as a keyframe.
|
585 |
+
|
586 |
+
state
|
587 |
+
A pseudo random integer, primarily derived from the content of
|
588 |
+
packet payload.
|
589 |
+
|
590 |
+
Examples
|
591 |
+
|
592 |
+
Apply modification to every byte but don't drop any packets.
|
593 |
+
|
594 |
+
ffmpeg -i INPUT -c copy -bsf noise=1 output.mkv
|
595 |
+
|
596 |
+
Drop every video packet not marked as a keyframe after timestamp 30s
|
597 |
+
but do not modify any of the remaining packets.
|
598 |
+
|
599 |
+
ffmpeg -i INPUT -c copy -bsf:v noise=drop='gt(t\,30)*not(key)' output.mkv
|
600 |
+
|
601 |
+
Drop one second of audio every 10 seconds and add some random noise to
|
602 |
+
the rest.
|
603 |
+
|
604 |
+
ffmpeg -i INPUT -c copy -bsf:a noise=amount=-1:drop='between(mod(t\,10)\,9\,10)' output.mkv
|
605 |
+
|
606 |
+
null
|
607 |
+
This bitstream filter passes the packets through unchanged.
|
608 |
+
|
609 |
+
pcm_rechunk
|
610 |
+
Repacketize PCM audio to a fixed number of samples per packet or a
|
611 |
+
fixed packet rate per second. This is similar to the asetnsamples audio
|
612 |
+
filter but works on audio packets instead of audio frames.
|
613 |
+
|
614 |
+
nb_out_samples, n
|
615 |
+
Set the number of samples per each output audio packet. The number
|
616 |
+
is intended as the number of samples per each channel. Default
|
617 |
+
value is 1024.
|
618 |
+
|
619 |
+
pad, p
|
620 |
+
If set to 1, the filter will pad the last audio packet with
|
621 |
+
silence, so that it will contain the same number of samples (or
|
622 |
+
roughly the same number of samples, see frame_rate) as the previous
|
623 |
+
ones. Default value is 1.
|
624 |
+
|
625 |
+
frame_rate, r
|
626 |
+
This option makes the filter output a fixed number of packets per
|
627 |
+
second instead of a fixed number of samples per packet. If the
|
628 |
+
audio sample rate is not divisible by the frame rate then the
|
629 |
+
number of samples will not be constant but will vary slightly so
|
630 |
+
that each packet will start as close to the frame boundary as
|
631 |
+
possible. Using this option has precedence over nb_out_samples.
|
632 |
+
|
633 |
+
You can generate the well known 1602-1601-1602-1601-1602 pattern of
|
634 |
+
48kHz audio for NTSC frame rate using the frame_rate option.
|
635 |
+
|
636 |
+

|
637 |
+
|
638 |
+
pgs_frame_merge
|
639 |
+
Merge a sequence of PGS Subtitle segments ending with an "end of
|
640 |
+
display set" segment into a single packet.
|
641 |
+
|
642 |
+
This is required by some containers that support PGS subtitles (muxer
|
643 |
+
"matroska").

+
ffmpeg-devices - FFmpeg devices
|

+
|

+
DESCRIPTION
|
7 |
+
This document describes the input and output devices provided by the
|
8 |
+
libavdevice library.
|
9 |
+
|
10 |
+
DEVICE OPTIONS
|
11 |
+
The libavdevice library provides the same interface as libavformat.
|
12 |
+
Namely, an input device is considered like a demuxer, and an output
|
13 |
+
device like a muxer, and the interface and generic device options are
|
14 |
+
the same provided by libavformat (see the ffmpeg-formats manual).
|
15 |
+
|
16 |
+
In addition each input or output device may support so-called private
|
17 |
+
options, which are specific for that component.
|
18 |
+
|
19 |
+
Options may be set by specifying -option value in the FFmpeg tools, or
|
20 |
+
by setting the value explicitly in the device "AVFormatContext" options
|
21 |
+
or using the libavutil/opt.h API for programmatic use.
|
22 |
+
|
23 |
+
INPUT DEVICES
|
24 |
+
Input devices are configured elements in FFmpeg which enable accessing
|
25 |
+
the data coming from a multimedia device attached to your system.
|
26 |
+
|
27 |
+
When you configure your FFmpeg build, all the supported input devices
|
28 |
+
are enabled by default. You can list all available ones using the
|
29 |
+
configure option "--list-indevs".
|
30 |
+
|
31 |
+
You can disable all the input devices using the configure option
|
32 |
+
"--disable-indevs", and selectively enable an input device using the
|
33 |
+
option "--enable-indev=INDEV", or you can disable a particular input
|
34 |
+
device using the option "--disable-indev=INDEV".
|
35 |
+
|
36 |
+
The option "-devices" of the ff* tools will display the list of
|
37 |
+
supported input devices.
|
38 |
+
|
39 |
+
A description of the currently available input devices follows.
|
40 |
+
|
41 |
+
alsa
|
42 |
+
ALSA (Advanced Linux Sound Architecture) input device.
|
43 |
+
|
44 |
+
To enable this input device during configuration you need libasound
|
45 |
+
installed on your system.
|
46 |
+
|
47 |
+
This device allows capturing from an ALSA device. The name of the
|
48 |
+
device to capture has to be an ALSA card identifier.
|
49 |
+
|
50 |
+
An ALSA identifier has the syntax:
|
51 |
+
|
52 |
+
hw:<CARD>[,<DEV>[,<SUBDEV>]]
|
53 |
+
|
54 |
+
where the DEV and SUBDEV components are optional.
|
55 |
+
|
56 |
+
The three arguments (in order: CARD,DEV,SUBDEV) specify card number or
|
57 |
+
identifier, device number and subdevice number (-1 means any).
|
58 |
+
|
59 |
+
To see the list of cards currently recognized by your system check the
|
60 |
+
files /proc/asound/cards and /proc/asound/devices.
|
61 |
+
|
62 |
+
For example to capture with ffmpeg from an ALSA device with card id 0,
|
63 |
+
you may run the command:
|
64 |
+
|
65 |
+
ffmpeg -f alsa -i hw:0 alsaout.wav
|
66 |
+
|
67 |
+

|
71 |
+
|
72 |
+
sample_rate
|
73 |
+
Set the sample rate in Hz. Default is 48000.
|
74 |
+
|
75 |
+
channels
|
76 |
+
Set the number of channels. Default is 2.
|
77 |
+
|
78 |
+
android_camera
|
79 |
+
Android camera input device.
|
80 |
+
|
81 |
+
This input devices uses the Android Camera2 NDK API which is available
|
82 |
+
on devices with API level 24+. The availability of android_camera is
|
83 |
+
autodetected during configuration.
|
84 |
+
|
85 |
+
This device allows capturing from all cameras on an Android device,
|
86 |
+
which are integrated into the Camera2 NDK API.
|
87 |
+
|
88 |
+
The available cameras are enumerated internally and can be selected
|
89 |
+
with the camera_index parameter. The input file string is discarded.
|
90 |
+
|
91 |
+
Generally the back facing camera has index 0 while the front facing
|
92 |
+
camera has index 1.
|
93 |
+
|
94 |
+
Options
|
95 |
+
|
96 |
+
video_size
|
97 |
+
Set the video size given as a string such as 640x480 or hd720.
|
98 |
+
Falls back to the first available configuration reported by Android
|
99 |
+
if requested video size is not available or by default.
|
100 |
+
|
101 |
+
framerate
|
102 |
+
Set the video framerate. Falls back to the first available
|
103 |
+
configuration reported by Android if requested framerate is not
|
104 |
+
available or by default (-1).
|
105 |
+
|
106 |
+
camera_index
|
107 |
+
Set the index of the camera to use. Default is 0.
|
108 |
+
|
109 |
+
input_queue_size
|
110 |
+
Set the maximum number of frames to buffer. Default is 5.
|
111 |
+
|
112 |
+
avfoundation
|
113 |
+
AVFoundation input device.
|
114 |
+
|
115 |
+
AVFoundation is the currently recommended framework by Apple for
|
116 |
+
streamgrabbing on OSX >= 10.7 as well as on iOS.
|
117 |
+
|
118 |
+
The input filename has to be given in the following syntax:
|
119 |
+
|
120 |
+
-i "[[VIDEO]:[AUDIO]]"
|
121 |
+
|
122 |
+
The first entry selects the video input while the latter selects the
|
123 |
+
audio input. The stream has to be specified by the device name or the
|
124 |
+
device index as shown by the device list. Alternatively, the video
|
125 |
+
and/or audio input device can be chosen by index using the
|
126 |
+
|
127 |
+
B<-video_device_index E<lt>INDEXE<gt>>
|
128 |
+
|
129 |
+
and/or
|
130 |
+
|
131 |
+
B<-audio_device_index E<lt>INDEXE<gt>>
|
132 |
+
|
133 |
+
, overriding any device name or index given in the input filename.
|
134 |
+
|
135 |
+
All available devices can be enumerated by using -list_devices true,
|
136 |
+
listing all device names and corresponding indices.
|
137 |
+
|
138 |
+
There are two device name aliases:
|
139 |
+
|
140 |
+
"default"
|
141 |
+
Select the AVFoundation default device of the corresponding type.
|
142 |
+
|
143 |
+
"none"
|
144 |
+
Do not record the corresponding media type. This is equivalent to
|
145 |
+
specifying an empty device name or index.
|
146 |
+
|
147 |
+
Options
|
148 |
+
|
149 |
+
AVFoundation supports the following options:
|
150 |
+
|
151 |
+
-list_devices <TRUE|FALSE>
|
152 |
+
If set to true, a list of all available input devices is given
|
153 |
+
showing all device names and indices.
|
154 |
+
|
155 |
+
-video_device_index <INDEX>
|
156 |
+
Specify the video device by its index. Overrides anything given in
|
157 |
+
the input filename.
|
158 |
+
|
159 |
+
-audio_device_index <INDEX>
|
160 |
+
Specify the audio device by its index. Overrides anything given in
|
161 |
+
the input filename.
|
162 |
+
|
163 |
+
-pixel_format <FORMAT>
|
164 |
+
Request the video device to use a specific pixel format. If the
|
165 |
+
specified format is not supported, a list of available formats is
|
166 |
+
given and the first one in this list is used instead. Available
|
167 |
+
pixel formats are: "monob, rgb555be, rgb555le, rgb565be, rgb565le,
|
168 |
+
rgb24, bgr24, 0rgb, bgr0, 0bgr, rgb0,
|
169 |
+
bgr48be, uyvy422, yuva444p, yuva444p16le, yuv444p, yuv422p16,
|
170 |
+
yuv422p10, yuv444p10,
|
171 |
+
yuv420p, nv12, yuyv422, gray"
|
172 |
+
|
173 |
+
-framerate
|
174 |
+
Set the grabbing frame rate. Default is "ntsc", corresponding to a
|
175 |
+
frame rate of "30000/1001".
|
176 |
+
|
177 |
+
-video_size
|
178 |
+
Set the video frame size.
|
179 |
+
|
180 |
+
-capture_cursor
|
181 |
+
Capture the mouse pointer. Default is 0.
|
182 |
+
|
183 |
+
-capture_mouse_clicks
|
184 |
+
Capture the screen mouse clicks. Default is 0.
|
185 |
+
|
186 |
+
-capture_raw_data
|
187 |
+
Capture the raw device data. Default is 0. Using this option may
|
188 |
+
result in receiving the underlying data delivered to the
|
189 |
+
AVFoundation framework. E.g. for muxed devices that sends raw DV
|
190 |
+
data to the framework (like tape-based camcorders), setting this
|
191 |
+
option to false results in extracted video frames captured in the
|
192 |
+
designated pixel format only. Setting this option to true results
|
193 |
+
in receiving the raw DV stream untouched.
|
194 |
+
|
195 |
+

decklink
|
243 |
+
The decklink input device provides capture capabilities for Blackmagic
|
244 |
+
DeckLink devices.
|
245 |
+
|
246 |
+
To enable this input device, you need the Blackmagic DeckLink SDK and
|
247 |
+
you need to configure with the appropriate "--extra-cflags" and
|
248 |
+
"--extra-ldflags". On Windows, you need to run the IDL files through
|
249 |
+
widl.
|
250 |
+
|
251 |
+
DeckLink is very picky about the formats it supports. Pixel format of
|
252 |
+
the input can be set with raw_format. Framerate and video size must be
|
253 |
+
determined for your device with -list_formats 1. Audio sample rate is
|
254 |
+
always 48 kHz and the number of channels can be 2, 8 or 16. Note that
|
255 |
+
all audio channels are bundled in one single audio track.
|
256 |
+
|
257 |
+
Options
|
258 |
+
|
259 |
+
list_devices
|
260 |
+
If set to true, print a list of devices and exit. Defaults to
|
261 |
+
false. This option is deprecated, please use the "-sources" option
|
262 |
+
of ffmpeg to list the available input devices.
|
263 |
+
|
264 |
+
list_formats
|
265 |
+
If set to true, print a list of supported formats and exit.
|
266 |
+
Defaults to false.
|
267 |
+
|
268 |
+
format_code <FourCC>
|
269 |
+
This sets the input video format to the format given by the FourCC.
|
270 |
+
To see the supported values of your device(s) use list_formats.
|
271 |
+
Note that there is a FourCC 'pal ' that can also be used as pal (3
|
272 |
+
letters). Default behavior is autodetection of the input video
|
273 |
+
format, if the hardware supports it.
|
274 |
+
|
275 |
+
raw_format
|
276 |
+
Set the pixel format of the captured video. Available values are:
|
277 |
+
|
278 |
+
auto
|
279 |
+
This is the default which means 8-bit YUV 422 or 8-bit ARGB if
|
280 |
+
format autodetection is used, 8-bit YUV 422 otherwise.
|
281 |
+
|
282 |
+
uyvy422
|
283 |
+
8-bit YUV 422.
|
284 |
+
|
285 |
+
yuv422p10
|
286 |
+
10-bit YUV 422.
|
287 |
+
|
288 |
+
argb
|
289 |
+
8-bit RGB.
|
290 |
+
|
291 |
+
bgra
|
292 |
+
8-bit RGB.
|
293 |
+
|
294 |
+
rgb10
|
295 |
+
10-bit RGB.
|
296 |
+
|
297 |
+
teletext_lines
|
298 |
+
If set to nonzero, an additional teletext stream will be captured
|
299 |
+
from the vertical ancillary data. Both SD PAL (576i) and HD (1080i
|
300 |
+
or 1080p) sources are supported. In case of HD sources, OP47
|
301 |
+
packets are decoded.
|
302 |
+
|
303 |
+
This option is a bitmask of the SD PAL VBI lines captured,
|
304 |
+
specifically lines 6 to 22, and lines 318 to 335. Line 6 is the LSB
|
305 |
+
in the mask. Selected lines which do not contain teletext
|
306 |
+
information will be ignored. You can use the special all constant
|
307 |
+
to select all possible lines, or standard to skip lines 6, 318 and
|
308 |
+
319, which are not compatible with all receivers.
|
309 |
+
|
310 |
+
For SD sources, ffmpeg needs to be compiled with
|
311 |
+
"--enable-libzvbi". For HD sources, on older (pre-4K) DeckLink card
|
312 |
+
models you have to capture in 10 bit mode.
|
313 |
+
|
314 |
+
channels
|
315 |
+
Defines number of audio channels to capture. Must be 2, 8 or 16.
|
316 |
+
Defaults to 2.
|
317 |
+
|
318 |
+
duplex_mode
|
319 |
+
Sets the decklink device duplex/profile mode. Must be unset, half,
|
320 |
+
full, one_sub_device_full, one_sub_device_half,
|
321 |
+
two_sub_device_full, four_sub_device_half Defaults to unset.
|
322 |
+
|
323 |
+
Note: DeckLink SDK 11.0 have replaced the duplex property by a
|
324 |
+
profile property. For the DeckLink Duo 2 and DeckLink Quad 2, a
|
325 |
+
profile is shared between any 2 sub-devices that utilize the same
|
326 |
+
connectors. For the DeckLink 8K Pro, a profile is shared between
|
327 |
+
all 4 sub-devices. So DeckLink 8K Pro support four profiles.
|
328 |
+
|
329 |
+
Valid profile modes for DeckLink 8K Pro(with DeckLink SDK >= 11.0):
|
330 |
+
one_sub_device_full, one_sub_device_half, two_sub_device_full,
|
331 |
+
four_sub_device_half
|
332 |
+
|
333 |
+
Valid profile modes for DeckLink Quad 2 and DeckLink Duo 2: half,
|
334 |
+
full
|
335 |
+
|
336 |
+
timecode_format

Timecode type to include in the frame and video stream metadata.
|
338 |
+
Must be none, rp188vitc, rp188vitc2, rp188ltc, rp188hfr, rp188any,
|
339 |
+
vitc, vitc2, or serial. Defaults to none (not included).
|
340 |
+
|
341 |
+
In order to properly support 50/60 fps timecodes, the ordering of
|
342 |
+
the queried timecode types for rp188any is HFR, VITC1, VITC2 and
|
343 |
+
LTC for >30 fps content. Note that this is slightly different to
|
344 |
+
the ordering used by the DeckLink API, which is HFR, VITC1, LTC,
|
345 |
+
VITC2.
|
346 |
+
|
347 |
+
video_input
|
348 |
+
Sets the video input source. Must be unset, sdi, hdmi, optical_sdi,
|
349 |
+
component, composite or s_video. Defaults to unset.
|
350 |
+
|
351 |
+
audio_input
|
352 |
+
Sets the audio input source. Must be unset, embedded, aes_ebu,
|
353 |
+
analog, analog_xlr, analog_rca or microphone. Defaults to unset.
|
354 |
+
|
355 |
+
video_pts
|
356 |
+
Sets the video packet timestamp source. Must be video, audio,
|
357 |
+
reference, wallclock or abs_wallclock. Defaults to video.
|
358 |
+
|
359 |
+
audio_pts
|
360 |
+
Sets the audio packet timestamp source. Must be video, audio,
|
361 |
+
reference, wallclock or abs_wallclock. Defaults to audio.
|
362 |
+
|
363 |
+
draw_bars
|
364 |
+
If set to true, color bars are drawn in the event of a signal loss.
|
365 |
+
Defaults to true.
|
366 |
+
|
367 |
+
queue_size
|
368 |
+
Sets maximum input buffer size in bytes. If the buffering reaches
|
369 |
+
this value, incoming frames will be dropped. Defaults to
|
370 |
+
1073741824.
|
371 |
+
|
372 |
+
audio_depth
|
373 |
+
Sets the audio sample bit depth. Must be 16 or 32. Defaults to 16.
|
374 |
+
|
375 |
+
decklink_copyts
|
376 |
+
If set to true, timestamps are forwarded as they are without
|
377 |
+
removing the initial offset. Defaults to false.
|
378 |
+
|
379 |
+
timestamp_align
|
380 |
+
Capture start time alignment in seconds. If set to nonzero, input
|
381 |
+
frames are dropped till the system timestamp aligns with configured
|
382 |
+
value. Alignment difference of up to one frame duration is
|
383 |
+
tolerated. This is useful for maintaining input synchronization
|
384 |
+
across N different hardware devices deployed for 'N-way'
|
385 |
+
redundancy. The system time of different hardware devices should be
|
386 |
+
synchronized with protocols such as NTP or PTP, before using this
|
387 |
+
option. Note that this method is not foolproof. In some border
|
388 |
+
cases input synchronization may not happen due to thread scheduling
|
389 |
+
jitters in the OS. Either sync could go wrong by 1 frame or in a
|
390 |
+
rarer case timestamp_align seconds. Defaults to 0.
|
391 |
+
|
392 |
+
wait_for_tc (bool)
|
393 |
+
Drop frames till a frame with timecode is received. Sometimes
|
394 |
+
serial timecode isn't received with the first input frame. If that
|
395 |
+
happens, the stored stream timecode will be inaccurate. If this
|
396 |
+
option is set to true, input frames are dropped till a frame with
|
397 |
+
timecode is received. Option timecode_format must be specified.
|
398 |
+
Defaults to false.
|
399 |
+
|
400 |
+
enable_klv(bool)
|
401 |
+
If set to true, extracts KLV data from VANC and outputs KLV
|
402 |
+
packets. KLV VANC packets are joined based on MID and PSC fields
|
403 |
+
and aggregated into one KLV packet. Defaults to false.
|
404 |
+
|
405 |

dshow
|
428 |
+
Windows DirectShow input device.
|
429 |
+
|
430 |
+
DirectShow support is enabled when FFmpeg is built with the mingw-w64
|
431 |
+
project. Currently only audio and video devices are supported.
|
432 |
+
|
433 |
+
Multiple devices may be opened as separate inputs, but they may also be
|
434 |
+
opened on the same input, which should improve synchronism between
|
435 |
+
them.
|
436 |
+
|
437 |
+
The input name should be in the format:
|
438 |
+
|
439 |
+
<TYPE>=<NAME>[:<TYPE>=<NAME>]
|
440 |
+
|
441 |
+
where TYPE can be either audio or video, and NAME is the device's name
|
442 |
+
or alternative name..
|
443 |
+
|
444 |
+

+
audio_buffer_size
|
483 |
+
Set audio device buffer size in milliseconds (which can directly
|
484 |
+
impact latency, depending on the device). Defaults to using the
|
485 |
+
audio device's default buffer size (typically some multiple of
|
486 |

show_video_device_dialog
|
509 |
+
If set to true, before capture starts, popup a display dialog to
|
510 |
+
the end user, allowing them to change video filter properties and
|
511 |

|
545 |
+
audio_device_load
|
546 |
+
Load an audio capture filter device from file instead of searching
|
547 |
+
it by name. It may load additional parameters too, if the filter
|
548 |
+
supports the serialization of its properties to. To use this an

|
550 |
+
even fake one.
|
551 |
+
|
552 |
+
audio_device_save
|
553 |
+

|
568 |
+
|
569 |
+
use_video_device_timestamps
|
570 |
+
If set to false, the timestamp for video frames will be derived
|
571 |
+
from the wallclock instead of the timestamp provided by the capture
|
572 |
+
device. This allows working around devices that provide unreliable
|
573 |
+
timestamps.
|
574 |
+
|
575 |
+
Examples
|
576 |
+

fbdev
|
609 |
+
Linux framebuffer input device.
|
610 |
+
|
611 |
+
The Linux framebuffer is a graphic hardware-independent abstraction
|
612 |
+
layer to show graphics on a computer monitor, typically on the console.
|
613 |
+
It is accessed through a file device node, usually /dev/fb0.
|
614 |
+
|
615 |
+
For more detailed information read the file
|
616 |
+
Documentation/fb/framebuffer.txt included in the Linux source tree.
|
617 |
+
|
618 |
+
See also <http://linux-fbdev.sourceforge.net/>, and fbset(1).
|
619 |
+
|
620 |
+
To record from the framebuffer device /dev/fb0 with ffmpeg:
|
621 |
+
|
622 |
+
ffmpeg -f fbdev -framerate 10 -i /dev/fb0 out.avi
|
623 |
+
|
624 |
+
You can take a single screenshot image with the command:
|
625 |
+
|
626 |
+
ffmpeg -f fbdev -framerate 1 -i /dev/fb0 -frames:v 1 screenshot.jpeg
|
627 |
+
|
628 |
+
Options
|
629 |
+
|
630 |
+
framerate
|
631 |
+
Set the frame rate. Default is 25.
|
632 |
+
|
633 |
+
gdigrab
|
634 |
+
Win32 GDI-based screen capture device.
|
635 |
+
|
636 |
+
This device allows you to capture a region of the display on Windows.
|
637 |
+
|
638 |
+
There are two options for the input filename:
|
639 |
+
|
640 |
+
desktop
|
641 |
+
|
642 |
+
or
|
643 |
+
|
644 |
+
title=<window_title>
|
645 |
+
|
646 |
+
The first option will capture the entire desktop, or a fixed region of
|
647 |
+
the desktop. The second option will instead capture the contents of a
|
648 |
+
single window, regardless of its position on the screen.
|
649 |
+
|
650 |
+
For example, to grab the entire desktop using ffmpeg:
|
651 |
+
|
652 |
+
ffmpeg -f gdigrab -framerate 6 -i desktop out.mpg
|
653 |
+
|
654 |
+
Grab a 640x480 region at position "10,20":
|
655 |
+
|
656 |
+
ffmpeg -f gdigrab -framerate 6 -offset_x 10 -offset_y 20 -video_size vga -i desktop out.mpg
|
657 |
+
|
658 |
+
Grab the contents of the window named "Calculator"
|
659 |
+
|
660 |
+
ffmpeg -f gdigrab -framerate 6 -i title=Calculator out.mpg
|
661 |
+
|
662 |
+
Options
|
663 |
+
|
664 |
+
draw_mouse
|
665 |
+
Specify whether to draw the mouse pointer. Use the value 0 to not
|
666 |
+
draw the pointer. Default value is 1.
|
667 |
+
|
668 |
+
framerate
|
669 |
+
Set the grabbing frame rate. Default value is "ntsc", corresponding
|
670 |
+
to a frame rate of "30000/1001".
|
671 |
+
|
672 |
+
show_region
|
673 |
+
Show grabbed region on screen.
|
674 |
+
|
675 |
+
If show_region is specified with 1, then the grabbing region will
|
676 |
+
be indicated on screen. With this option, it is easy to know what
|
677 |
+
is being grabbed if only a portion of the screen is grabbed.
|
678 |
+
|
679 |
+
Note that show_region is incompatible with grabbing the contents of
|
680 |
+
a single window.
|
681 |
+
|
682 |
+
For example:
|
683 |
+
|
684 |
+
ffmpeg -f gdigrab -show_region 1 -framerate 6 -video_size cif -offset_x 10 -offset_y 20 -i desktop out.mpg
|
685 |
+
|
686 |
+
video_size
|
687 |
+
Set the video frame size. The default is to capture the full screen
|
688 |
+
if desktop is selected, or the full window size if
|
689 |
+
title=window_title is selected.
|
690 |
+
|
691 |
+
offset_x
|
692 |
+
When capturing a region with video_size, set the distance from the
|
693 |
+

|
695 |
+
Note that the offset calculation is from the top left corner of the
|
696 |
+
primary monitor on Windows. If you have a monitor positioned to the
|
697 |
+
left of your primary monitor, you will need to use a negative
|
698 |
+
offset_x value to move the region to that monitor.
|
699 |
+
|
700 |
+
offset_y
|
701 |
+
When capturing a region with video_size, set the distance from the
|
702 |
+
top edge of the screen or desktop.
|
703 |
+

704 |
+
Note that the offset calculation is from the top left corner of the

iec61883
|
710 |
+
FireWire DV/HDV input device using libiec61883.
|
711 |
+
|
712 |
+
To enable this input device, you need libiec61883, libraw1394 and
|
713 |
+
libavc1394 installed on your system. Use the configure option
|
714 |
+
"--enable-libiec61883" to compile with the device enabled.
|
715 |
+
|
716 |
+
The iec61883 capture device supports capturing from a video device
|
717 |
+
connected via IEEE1394 (FireWire), using libiec61883 and the new Linux
|
718 |
+
FireWire stack (juju). This is the default DV/HDV input method in Linux
|
719 |
+
Kernel 2.6.37 and later, since the old FireWire stack was removed.
|
720 |
+
|
721 |
+
Specify the FireWire port to be used as input file, or "auto" to choose
|
722 |
+
the first port connected.
|
723 |
+
|
724 |
+
Options
|
725 |
+
|
726 |
+
dvtype
|
727 |
+
Override autodetection of DV/HDV. This should only be used if auto
|
728 |
+
detection does not work, or if usage of a different device type
|
729 |
+
should be prohibited. Treating a DV device as HDV (or vice versa)
|
730 |
+
will not work and result in undefined behavior. The values auto,
|
731 |
+
dv and hdv are supported.
|
732 |
+
|
733 |
+
dvbuffer
|
734 |
+
Set maximum size of buffer for incoming data, in frames. For DV,
|
735 |
+
this is an exact value. For HDV, it is not frame exact, since HDV
|
736 |
+
does not have a fixed frame size.
|
737 |
+
|
738 |
+
dvguid
|
739 |
+
Select the capture device by specifying its GUID. Capturing will
|
740 |
+
only be performed from the specified device and fails if no device
|
741 |
+
with the given GUID is found. This is useful to select the input if
|
742 |
+
multiple devices are connected at the same time. Look at
|
743 |
+
/sys/bus/firewire/devices to find out the GUIDs.
|
744 |
+
|
745 |
+
Examples
|
746 |
+
|
747 |
+
o Grab and show the input of a FireWire DV/HDV device.
|
748 |
+
|
749 |
+
ffplay -f iec61883 -i auto
|
750 |
+
|
751 |
+
o Grab and record the input of a FireWire DV/HDV device, using a
|
752 |
+
packet buffer of 100000 packets if the source is HDV.

jack
|
757 |
+
JACK input device.
|
758 |
+
|
759 |
+
To enable this input device during configuration you need libjack
|
760 |
+
installed on your system.
|
761 |
+
|
762 |
+
A JACK input device creates one or more JACK writable clients, one for
|
763 |
+
each audio channel, with name client_name:input_N, where client_name is
|
764 |
+
the name provided by the application, and N is a number which
|
765 |
+
identifies the channel. Each writable client will send the acquired
|
766 |
+
data to the FFmpeg input device.
|
767 |
+
|
768 |
+
Once you have created one or more JACK readable clients, you need to
|
769 |
+
connect them to one or more JACK writable clients.
|
770 |
+
|
771 |
+
To connect or disconnect JACK clients you can use the jack_connect and
|
772 |
+
jack_disconnect programs, or do it through a graphical interface, for
|
773 |
+
example with qjackctl.
|
774 |
+
|
775 |
+
To list the JACK clients and their properties you can invoke the
|
776 |
+
command jack_lsp.
|
777 |
+
|
778 |
+
Follows an example which shows how to capture a JACK readable client
|
779 |
+
with ffmpeg.
|
780 |
+
|
781 |
+
# Create a JACK writable client with name "ffmpeg".
|
782 |
+
$ ffmpeg -f jack -i ffmpeg -y out.wav
|
783 |
+
|
784 |
+
# Start the sample jack_metro readable client.
|
785 |
+
$ jack_metro -b 120 -d 0.2 -f 4000
|
786 |
+
|
787 |
+
# List the current JACK clients.
|
788 |

kmsgrab
|
807 |
+
KMS video input device.
|
808 |
+
|
809 |
+
Captures the KMS scanout framebuffer associated with a specified CRTC
|
810 |
+
or plane as a DRM object that can be passed to other hardware
|
811 |
+
functions.
|
812 |
+
|
813 |
+
Requires either DRM master or CAP_SYS_ADMIN to run.
|
814 |
+
|
815 |
+
If you don't understand what all of that means, you probably don't want
|
816 |
+
this. Look at x11grab instead.
|
817 |
+
|
818 |
+
Options
|
819 |
+
|
820 |
+
device
|
821 |
+
DRM device to capture on. Defaults to /dev/dri/card0.
|
822 |
+
|
823 |
+
format
|
824 |
+
Pixel format of the framebuffer. This can be autodetected if you
|
825 |
+
are running Linux 5.7 or later, but needs to be provided for
|
826 |
+
earlier versions. Defaults to bgr0, which is the most common
|
827 |
+
format used by the Linux console and Xorg X server.
|
828 |
+
|
829 |
+
format_modifier
|
830 |
+
Format modifier to signal on output frames. This is necessary to
|
831 |
+
import correctly into some APIs. It can be autodetected if you are
|
832 |
+
running Linux 5.7 or later, but will need to be provided explicitly
|
833 |
+
when needed in earlier versions. See the libdrm documentation for
|
834 |
+
possible values.
|
835 |
+
|
836 |
+
crtc_id
|
837 |
+
KMS CRTC ID to define the capture source. The first active plane
|
838 |
+
on the given CRTC will be used.
|
839 |
+
|
840 |
+
plane_id
|
841 |
+
KMS plane ID to define the capture source. Defaults to the first
|
842 |
+
active plane found if neither crtc_id nor plane_id are specified.
|
843 |
+
|
844 |
+
framerate
|
845 |
+
Framerate to capture at. This is not synchronised to any page
|
846 |
+
flipping or framebuffer changes - it just defines the interval at
|
847 |
+
which the framebuffer is sampled. Sampling faster than the
|
848 |
+
framebuffer update rate will generate independent frames with the
|
849 |
+
same content. Defaults to 30.
|
850 |
+
|
851 |
+
Examples
|
852 |
+
|
853 |
+
o Capture from the first active plane, download the result to normal
|
854 |
+
frames and encode. This will only work if the framebuffer is both
|
855 |
+
linear and mappable - if not, the result may be scrambled or fail
|
856 |
+
to download.
|
857 |
+
|
858 |
+
ffmpeg -f kmsgrab -i - -vf 'hwdownload,format=bgr0' output.mp4
|
859 |
+
|
860 |
+
o Capture from CRTC ID 42 at 60fps, map the result to VAAPI, convert
|
861 |
+
to NV12 and encode as H.264.
|
862 |
+
|
863 |
+
ffmpeg -crtc_id 42 -framerate 60 -f kmsgrab -i - -vf 'hwmap=derive_device=vaapi,scale_vaapi=w=1920:h=1080:format=nv12' -c:v h264_vaapi output.mp4
|
864 |
+
|
865 |
+
o To capture only part of a plane the output can be cropped - this
|
866 |
+
can be used to capture a single window, as long as it has a known
|
867 |
+
absolute position and size. For example, to capture and encode the
|
868 |
+
middle quarter of a 1920x1080 plane:
|
869 |
+
|
870 |
+
ffmpeg -f kmsgrab -i - -vf 'hwmap=derive_device=vaapi,crop=960:540:480:270,scale_vaapi=960:540:nv12' -c:v h264_vaapi output.mp4
|
871 |
+
|
872 |
+
lavfi
|
873 |
+
Libavfilter input virtual device.
|
874 |
+
|
875 |
+
This input device reads data from the open output pads of a libavfilter
|
876 |
+
filtergraph.
|
877 |
+
|
878 |
+
For each filtergraph open output, the input device will create a
|
879 |
+
corresponding stream which is mapped to the generated output. Currently
|
880 |
+
only video data is supported. The filtergraph is specified through the
|
881 |
+
option graph.
|
882 |
+
|
883 |
+
Options
|
884 |
+
|
885 |
+
graph
|
886 |
+
Specify the filtergraph to use as input. Each video open output
|
887 |
+
must be labelled by a unique string of the form "outN", where N is
|
888 |
+
a number starting from 0 corresponding to the mapped input stream
|
889 |
+
generated by the device. The first unlabelled output is
|
890 |
+
automatically assigned to the "out0" label, but all the others need
|
891 |
+
to be specified explicitly.
|
892 |
+
|
893 |
+
The suffix "+subcc" can be appended to the output label to create
|
894 |
+
an extra stream with the closed captions packets attached to that
|
895 |
+
output (experimental; only for EIA-608 / CEA-708 for now). The
|
896 |
+
subcc streams are created after all the normal streams, in the
|
897 |
+
order of the corresponding stream. For example, if there is
|
898 |
+
"out19+subcc", "out7+subcc" and up to "out42", the stream #43 is
|
899 |
+
subcc for stream #7 and stream #44 is subcc for stream #19.
|
900 |
+
|
901 |
+
If not specified defaults to the filename specified for the input
|
902 |
+
device.
|
903 |
+
|
904 |
+
graph_file
|
905 |
+
Set the filename of the filtergraph to be read and sent to the
|
906 |
+
other filters. Syntax of the filtergraph is the same as the one
|
907 |
+
specified by the option graph.
|
908 |
+
|
909 |
+
dumpgraph
|
910 |
+
Dump graph to stderr.
|
911 |
+
|
912 |
+
Examples
|
913 |
+
|
914 |
+
o Create a color video stream and play it back with ffplay:
|
915 |
+
|
916 |
+
ffplay -f lavfi -graph "color=c=pink [out0]" dummy
|
917 |
+
|
918 |
+
o As the previous example, but use filename for specifying the graph
|
919 |
+
description, and omit the "out0" label:
|
920 |
+
|
921 |
+
ffplay -f lavfi color=c=pink
|
922 |
+
|
923 |
+
o Create three different video test filtered sources and play them:
|
924 |
+
|
925 |
+
ffplay -f lavfi -graph "testsrc [out0]; testsrc,hflip [out1]; testsrc,negate [out2]" test3
|
926 |
+
|
927 |
+
o Read an audio stream from a file using the amovie source and play
|
928 |
+
it back with ffplay:
|
929 |
+
|
930 |
+
ffplay -f lavfi "amovie=test.wav"
|
931 |
+
|
932 |
+
o Read an audio stream and a video stream and play it back with
|
933 |
+
ffplay:
|
934 |
+
|
935 |
+
ffplay -f lavfi "movie=test.avi[out0];amovie=test.wav[out1]"
|
936 |
+
|
937 |
+
o Dump decoded frames to images and closed captions to a file
|
938 |
+
(experimental):
|
939 |
+
|
940 |
+
ffmpeg -f lavfi -i "movie=test.ts[out0+subcc]" -map v frame%08d.png -map s -c copy -f rawvideo subcc.bin

The speed is specified CD-ROM speed units. The speed is set through
|
962 |
+
the libcdio "cdio_cddap_speed_set" function. On many CD-ROM drives,
|
963 |
+
specifying a value too large will result in using the fastest
|
964 |

OpenAL headers and libraries should be provided as part of your OpenAL
|
1008 |
+
implementation, or as an additional download (an SDK). Depending on
|
1009 |
+
your installation you may need to specify additional flags via the
|
1010 |
+
"--extra-cflags" and "--extra-ldflags" for allowing the build system to
|
1011 |
+
locate the OpenAL headers and libraries.

video4linux2, v4l2
|
1174 |
+
Video4Linux2 input video device.
|
1175 |
+
|
1176 |
+
"v4l2" can be used as alias for "video4linux2".
|
1177 |
+
|
1178 |
+
If FFmpeg is built with v4l-utils support (by using the
|
1179 |
+
"--enable-libv4l2" configure option), it is possible to use it with the
|
1180 |
+
"-use_libv4l2" input device option.
|
1181 |
+
|
1182 |
+
The name of the device to grab is a file device node, usually Linux
|
1183 |
+
systems tend to automatically create such nodes when the device (e.g.
|
1184 |
+
an USB webcam) is plugged into the system, and has a name of the kind
|
1185 |
+
/dev/videoN, where N is a number associated to the device.
|
1186 |
+
|
1187 |
+
Video4Linux2 devices usually support a limited set of widthxheight
|
1188 |
+
sizes and frame rates. You can check which are supported using
|
1189 |
+
-list_formats all for Video4Linux2 devices. Some devices, like TV
|
1190 |
+
cards, support one or more standards. It is possible to list all the
|
1191 |
+
supported standards using -list_standards all.
|
1192 |
+
|
1193 |
+
The time base for the timestamps is 1 microsecond. Depending on the
|
1194 |
+
kernel version and configuration, the timestamps may be derived from
|
1195 |
+
the real time clock (origin at the Unix Epoch) or the monotonic clock
|
1196 |
+
(origin usually at boot time, unaffected by NTP or manual changes to
|
1197 |
+
the clock). The -timestamps abs or -ts abs option can be used to force
|
1198 |
+
conversion into the real time clock.
|
1199 |
+
|
1200 |
+
Some usage examples of the video4linux2 device with ffmpeg and ffplay:
|
1201 |
+
|
1202 |
+
o List supported formats for a video4linux2 device:
|

x11grab
|
1297 |
+
X11 video input device.
|
1298 |
+
|
1299 |
+
To enable this input device during configuration you need libxcb
|
1300 |
+
installed on your system. It will be automatically detected during
|
1301 |
+
configuration.
|
1302 |
+
|
1303 |
+
This device allows one to capture a region of an X11 display.
|
1304 |
+
|
1305 |
+
The filename passed as input has the syntax:
|
1306 |
+
|
1307 |
+
[<hostname>]:<display_number>.<screen_number>[+<x_offset>,<y_offset>]
|
1308 |
+
|
1309 |
+
hostname:display_number.screen_number specifies the X11 display name of
|
1310 |
+
the screen to grab from. hostname can be omitted, and defaults to
|
1311 |
+
"localhost". The environment variable DISPLAY contains the default
|
1312 |
+
display name.
|
1313 |
+
|
1314 |
+
x_offset and y_offset specify the offsets of the grabbed area with
|
1315 |
+
respect to the top-left border of the X11 screen. They default to 0.
|
1316 |
+
|
1317 |
+
Check the X11 documentation (e.g. man X) for more detailed information.
|
1318 |
+
|
1319 |
+
Use the xdpyinfo program for getting basic information about the
|
1320 |
+
properties of your X11 display (e.g. grep for "name" or "dimensions").
|
1321 |
+
|
1322 |
+
For example to grab from :0.0 using ffmpeg:
|
1323 |
+
|
1324 |
+
ffmpeg -f x11grab -framerate 25 -video_size cif -i :0.0 out.mpg
|
1325 |
+
|
1326 |
+
Grab at position "10,20":
|
1327 |
+
|
1328 |
+
ffmpeg -f x11grab -framerate 25 -video_size cif -i :0.0+10,20 out.mpg
|
1329 |
+
|
1330 |
+
Options
|
1331 |
+
|
1332 |
+
select_region
|
1333 |
+
Specify whether to select the grabbing area graphically using the
|
1334 |
+
pointer. A value of 1 prompts the user to select the grabbing area
|
1335 |
+
graphically by clicking and dragging. A single click with no
|
1336 |
+
dragging will select the whole screen. A region with zero width or
|
1337 |
+
height will also select the whole screen. This option overwrites
|
1338 |
+
the video_size, grab_x, and grab_y options. Default value is 0.
|
1339 |
+
|
1340 |
+
draw_mouse
|
1341 |
+
Specify whether to draw the mouse pointer. A value of 0 specifies
|
1342 |
+
not to draw the pointer. Default value is 1.
|
1343 |
+
|
1344 |
+
follow_mouse
|
1345 |
+
Make the grabbed area follow the mouse. The argument can be
|
1346 |
+
"centered" or a number of pixels PIXELS.
|
1347 |
+
|
1348 |
+
When it is specified with "centered", the grabbing region follows
|
1349 |
+
the mouse pointer and keeps the pointer at the center of region;
|
1350 |
+
otherwise, the region follows only when the mouse pointer reaches
|
1351 |
+
within PIXELS (greater than zero) to the edge of region.
|
1352 |
+
|
1353 |
+
For example:
|
1354 |
+
|
1355 |
+
ffmpeg -f x11grab -follow_mouse centered -framerate 25 -video_size cif -i :0.0 out.mpg
|
1356 |
+
|
1357 |
+
To follow only when the mouse pointer reaches within 100 pixels to
|
1358 |
+
edge:
|
1359 |
+
|
1360 |
+
ffmpeg -f x11grab -follow_mouse 100 -framerate 25 -video_size cif -i :0.0 out.mpg
|
1361 |
+
|
1362 |
+
framerate
|
1363 |
+
Set the grabbing frame rate. Default value is "ntsc", corresponding
|
1364 |
+
to a frame rate of "30000/1001".
|
1365 |
+
|
1366 |
+
show_region
|
1367 |
+
Show grabbed region on screen.
|
1368 |
+
|
1369 |
+
If show_region is specified with 1, then the grabbing region will
|
1370 |
+
be indicated on screen. With this option, it is easy to know what
|
1371 |
+
is being grabbed if only a portion of the screen is grabbed.
|
1372 |
+
|
1373 |
+
region_border
|
1374 |
+
Set the region border thickness if -show_region 1 is used. Range
|
1375 |
+
is 1 to 128 and default is 3 (XCB-based x11grab only).
|
1376 |
+
|
1377 |
+
For example:
|
1378 |
+
|
1379 |
+
ffmpeg -f x11grab -show_region 1 -framerate 25 -video_size cif -i :0.0+10,20 out.mpg
|
1380 |
+
|
1381 |
+
With follow_mouse:
|
1382 |
+
|
1383 |
+
ffmpeg -f x11grab -follow_mouse centered -show_region 1 -framerate 25 -video_size cif -i :0.0 out.mpg
|
1384 |
+
|
1385 |
+
window_id
|
1386 |
+
Grab this window, instead of the whole screen. Default value is 0,
|
1387 |
+
which maps to the whole screen (root window).
|
1388 |
+
|
1389 |
+
The id of a window can be found using the xwininfo program,
|
1390 |
+
possibly with options -tree and -root.
|
1391 |
+
|
1392 |
+
If the window is later enlarged, the new area is not recorded.
|
1393 |
+
Video ends when the window is closed, unmapped (i.e., iconified) or
|
1394 |
+
shrunk beyond the video size (which defaults to the initial window
|
1395 |
+
size).
|
1396 |
+
|
1397 |
+
This option disables options follow_mouse and select_region.
|
1398 |
+
|
1399 |
+
video_size
|
1400 |
+
Set the video frame size. Default is the full desktop or window.
|
1401 |
+
|
1402 |
+
grab_x
|
1403 |
+
grab_y
|
1404 |
+
Set the grabbing region coordinates. They are expressed as offset
|
1405 |
+
from the top left corner of the X11 window and correspond to the
|
1406 |
+
x_offset and y_offset parameters in the device name. The default
|
1407 |
+
value for both options is 0.
|
1408 |
+
|
1409 |
+
OUTPUT DEVICES
|
1410 |
+
Output devices are configured elements in FFmpeg that can write
|
1411 |
+
multimedia data to an output device attached to your system.
|
1412 |
+
|
1413 |
+
When you configure your FFmpeg build, all the supported output devices
|
1414 |
+
are enabled by default. You can list all available ones using the
|
1415 |
+
configure option "--list-outdevs".
|
1416 |
+
|
1417 |
+
You can disable all the output devices using the configure option
|
1418 |
+
"--disable-outdevs", and selectively enable an output device using the
|
1419 |
+
option "--enable-outdev=OUTDEV", or you can disable a particular input
|
1420 |
+
device using the option "--disable-outdev=OUTDEV".
|
1421 |

1443 |
+
Allows native output to CoreAudio devices on OSX.
|
1444 |
+
|
1445 |
+
The output filename can be empty (or "-") to refer to the default
|
1446 |
+
system output device or a number that refers to the device index as
|
1447 |
+
shown using: "-list_devices true".
|
1448 |
+
|
1449 |
+
Alternatively, the audio input device can be chosen by index using the
|
1450 |
+
|
1451 |
+
B<-audio_device_index E<lt>INDEXE<gt>>
|
1452 |

decklink
|
1549 |
+
The decklink output device provides playback capabilities for
|
1550 |
+
Blackmagic DeckLink devices.
|
1551 |
+
|
1552 |
+
To enable this output device, you need the Blackmagic DeckLink SDK and
|
1553 |
+
you need to configure with the appropriate "--extra-cflags" and
|
1554 |
+
"--extra-ldflags". On Windows, you need to run the IDL files through
|
1555 |
+
widl.
|
1556 |
+
|
1557 |
+
DeckLink is very picky about the formats it supports. Pixel format is
|
1558 |
+
always uyvy422, framerate, field order and video size must be
|
1559 |
+
determined for your device with -list_formats 1. Audio sample rate is
|
1560 |
+
always 48 kHz.
|
1561 |
+
|
1562 |
+

|
1580 |
+
|
1581 |

profile property. For the DeckLink Duo 2 and DeckLink Quad 2, a
|
1583 |
+
profile is shared between any 2 sub-devices that utilize the same
|
1584 |
+
connectors. For the DeckLink 8K Pro, a profile is shared between
|
1585 |
+
all 4 sub-devices. So DeckLink 8K Pro support four profiles.
|
1586 |
+
|
1587 |
+

1654 |
+
OpenGL output device.
|
1655 |
+
|
1656 |
+
To enable this output device you need to configure FFmpeg with
|
1657 |
+
"--enable-opengl".
|
1658 |
+
|
1659 |
+
This output device allows one to render to OpenGL context. Context may
|
1660 |
+
be provided by application or default SDL window is created.
|
1661 |
+
|
1662 |
+
When device renders to external context, application must implement
|
1663 |
+
handlers for following messages: "AV_DEV_TO_APP_CREATE_WINDOW_BUFFER" -
|
1664 |
+
create OpenGL context on current thread.

"AV_DEV_TO_APP_DISPLAY_WINDOW_BUFFER" - swap buffers.
|
1667 |
+
"AV_DEV_TO_APP_DESTROY_WINDOW_BUFFER" - destroy OpenGL context.
|
1668 |
+
Application is also required to inform a device about current
|
1669 |
+
resolution by sending "AV_APP_TO_DEV_WINDOW_SIZE" message.
|
1670 |
+
|
1671 |
+
Options
|
1672 |

|
1699 |
+
|
1700 |
+
pulse
|
1701 |
+
PulseAudio output device.
|
1702 |
+
|
1703 |
+
To enable this output device you need to configure FFmpeg with
|
1704 |
+
"--enable-libpulse".
|
1705 |
+
|
1706 |
+
More information about PulseAudio can be found on
|
1707 |
+
<http://www.pulseaudio.org>
|
1708 |
+
|
1709 |
+
Options
|
1710 |
+
|
1711 |
+
server
|
1712 |
+
Connect to a specific PulseAudio server, specified by an IP
|
1713 |
+
address. Default server is used when not provided.
|
1714 |
+
|
1715 |
+
name
|
1716 |
+
Specify the application name PulseAudio will use when showing
|
1717 |
+
active clients, by default it is the "LIBAVFORMAT_IDENT" string.
|
1718 |
+
|
1719 |
+
stream_name
|
1720 |
+
Specify the stream name PulseAudio will use when showing active
|
1721 |
+
streams, by default it is set to the specified output name.
|
1722 |
+
|
1723 |
+
device
|
1724 |
+
Specify the device to use. Default device is used when not
|
1725 |
+
provided. List of output devices can be obtained with command
|
1726 |
+
pactl list sinks.
|
1727 |
+
|
1728 |
+
buffer_size
|
1729 |
+
buffer_duration
|
1730 |
+
Control the size and duration of the PulseAudio buffer. A small
|
1731 |
+
buffer gives more control, but requires more frequent updates.
|
1732 |
+
|
1733 |
+
buffer_size specifies size in bytes while buffer_duration specifies
|
1734 |
+
duration in milliseconds.
|
1735 |
+
|
1736 |
+
When both options are provided then the highest value is used
|
1737 |
+
(duration is recalculated to bytes using stream parameters). If
|
1738 |
+
they are set to 0 (which is default), the device will use the
|
1739 |
+
default PulseAudio duration value. By default PulseAudio set buffer
|
1740 |
+
duration to around 2 seconds.
|
1741 |
+
|
1742 |
+
prebuf
|
1743 |
+
Specify pre-buffering size in bytes. The server does not start with
|
1744 |
+
playback before at least prebuf bytes are available in the buffer.
|
1745 |
+
By default this option is initialized to the same value as
|
1746 |
+
buffer_size or buffer_duration (whichever is bigger).
|
1747 |
+
|
1748 |
+
minreq
|
1749 |
+
Specify minimum request size in bytes. The server does not request
|
1750 |
+
less than minreq bytes from the client, instead waits until the
|
1751 |
+
buffer is free enough to request more bytes at once. It is
|
1752 |
+
recommended to not set this option, which will initialize this to a
|
1753 |
+
value that is deemed sensible by the server.
|
1754 |
+
|
1755 |
+
Examples
|
1756 |
+
|
1757 |
+
Play a file on default device on default server:

1765 |
+
|
1766 |
+
This output device allows one to show a video stream in an SDL window.
|
1767 |
+
Only one SDL window is allowed per application, so you can have only
|
1768 |
+
one instance of this output device in an application.
|
1769 |

NAME

ffmpeg-protocols - FFmpeg protocols
|

|

+
DESCRIPTION
|
7 |
+
This document describes the input and output protocols provided by the
|
8 |
+
libavformat library.
|
9 |
+
|
10 |
+
PROTOCOL OPTIONS
|
11 |
+
The libavformat library provides some generic global options, which can
|
12 |
+
be set on all the protocols. In addition each protocol may support so-
|
13 |
+
called private options, which are specific for that component.
|
14 |
+
|
15 |
+
Options may be set by specifying -option value in the FFmpeg tools, or
|
16 |
+
by setting the value explicitly in the "AVFormatContext" options or
|
17 |
+
using the libavutil/opt.h API for programmatic use.
|
18 |
+
|
19 |
+
The list of supported options follows:
|
20 |
+
|
21 |
+
protocol_whitelist list (input)
|
22 |
+
Set a ","-separated list of allowed protocols. "ALL" matches all
|
23 |
+
protocols. Protocols prefixed by "-" are disabled. All protocols
|
24 |
+
are allowed by default but protocols used by an another protocol
|
25 |
+
(nested protocols) are restricted to a per protocol subset.
|
26 |
+
|
27 |
+
PROTOCOLS
|
28 |
+
Protocols are configured elements in FFmpeg that enable access to
|
29 |
+
resources that require specific protocols.
|
30 |
+
|
31 |
+
When you configure your FFmpeg build, all the supported protocols are
|
32 |
+
enabled by default. You can list all available ones using the configure
|
33 |
+
option "--list-protocols".
|
34 |
+
|
35 |
+
You can disable all the protocols using the configure option
|
36 |
+
"--disable-protocols", and selectively enable a protocol using the
|
37 |
+
option "--enable-protocol=PROTOCOL", or you can disable a particular
|
38 |
+
protocol using the option "--disable-protocol=PROTOCOL".
|
39 |
+
|
40 |
+
The option "-protocols" of the ff* tools will display the list of
|
41 |
+
supported protocols.
|
42 |
+
|
43 |
+
All protocols accept the following options:
|
44 |
+
|
45 |
+
rw_timeout
|
46 |
+
Maximum time to wait for (network) read/write operations to
|
47 |
+
complete, in microseconds.
|
48 |
+
|
49 |
+
A description of the currently available protocols follows.
|
50 |
+
|
51 |
+
amqp
|
52 |
+
Advanced Message Queueing Protocol (AMQP) version 0-9-1 is a broker
|
53 |
+
based publish-subscribe communication protocol.
|
54 |
+
|
55 |
+
FFmpeg must be compiled with --enable-librabbitmq to support AMQP. A
|
56 |
+
separate AMQP broker must also be run. An example open-source AMQP
|
57 |
+
broker is RabbitMQ.
|
58 |
+
|
59 |
+
After starting the broker, an FFmpeg client may stream data to the
|
60 |
+
broker using the command:
|
61 |
+
|
62 |
+
ffmpeg -re -i input -f mpegts amqp://[[user]:[password]@]hostname[:port][/vhost]
|
63 |
+
|
64 |
+
Where hostname and port (default is 5672) is the address of the broker.
|
65 |
+
The client may also set a user/password for authentication. The default
|
66 |
+
for both fields is "guest". Name of virtual host on broker can be set
|
67 |
+
with vhost. The default value is "/".
|
68 |
+
|
69 |
+
Muliple subscribers may stream from the broker using the command:
|
70 |
+
|
71 |
+
ffplay amqp://[[user]:[password]@]hostname[:port][/vhost]
|
72 |
+
|
73 |
+
In RabbitMQ all data published to the broker flows through a specific
|
74 |
+
exchange, and each subscribing client has an assigned queue/buffer.
|
75 |
+
When a packet arrives at an exchange, it may be copied to a client's
|
76 |
+
queue depending on the exchange and routing_key fields.
|
77 |
+
|
78 |
+
The following options are supported:
|
79 |
+
|
80 |
+
exchange
|
81 |
+
Sets the exchange to use on the broker. RabbitMQ has several
|
82 |
+
predefined exchanges: "amq.direct" is the default exchange, where
|
83 |
+
the publisher and subscriber must have a matching routing_key;
|
84 |
+
"amq.fanout" is the same as a broadcast operation (i.e. the data is
|
85 |
+
forwarded to all queues on the fanout exchange independent of the
|
86 |
+
routing_key); and "amq.topic" is similar to "amq.direct", but
|
87 |
+
allows for more complex pattern matching (refer to the RabbitMQ
|
88 |
+
documentation).
|
89 |
+
|
90 |
+
routing_key
|
91 |
+
Sets the routing key. The default value is "amqp". The routing key
|
92 |
+
is used on the "amq.direct" and "amq.topic" exchanges to decide
|
93 |
+
whether packets are written to the queue of a subscriber.
|
94 |
+
|
95 |
+
pkt_size
|
96 |
+
Maximum size of each packet sent/received to the broker. Default is
|
97 |
+
131072. Minimum is 4096 and max is any large value (representable
|
98 |
+
by an int). When receiving packets, this sets an internal buffer
|
99 |
+
size in FFmpeg. It should be equal to or greater than the size of
|
100 |
+
the published packets to the broker. Otherwise the received message
|
101 |
+
may be truncated causing decoding errors.
|
102 |
+
|
103 |
+
connection_timeout
|
104 |
+
The timeout in seconds during the initial connection to the broker.
|
105 |
+
The default value is rw_timeout, or 5 seconds if rw_timeout is not

106 |
+
set.
|
107 |
+
|
108 |
+
delivery_mode mode
|
109 |
+
Sets the delivery mode of each message sent to broker. The
|
110 |
+
following values are accepted:
|
111 |
+
|
112 |
+
persistent
|
113 |
+
Delivery mode set to "persistent" (2). This is the default
|
114 |
+
value. Messages may be written to the broker's disk depending
|
115 |
+
on its setup.
|
116 |
+
|
117 |
+
non-persistent
|
118 |
+
Delivery mode set to "non-persistent" (1). Messages will stay
|
119 |

The accepted options are:
|
163 |
+
|
164 |
+
read_ahead_limit
|
165 |
+
Amount in bytes that may be read ahead when seeking isn't

180 |
+
|
181 |
+
concat:<URL1>|<URL2>|...|<URLN>
|
182 |
+
|
183 |
+
where URL1, URL2, ..., URLN are the urls of the resource to be
|
184 |
+
concatenated, each one possibly specifying a distinct protocol.
|
185 |
+
|
186 |
+
For example to read a sequence of files split1.mpeg, split2.mpeg,
|
187 |
+
split3.mpeg with ffplay use the command:
|
188 |
+
|
189 |
+
ffplay concat:split1.mpeg\|split2.mpeg\|split3.mpeg
|
190 |
+
|
191 |
+
Note that you may need to escape the character "|" which is special for

192 |
+
many shells.
|
193 |
+
|
194 |
+
concatf
|
195 |

|
202 |
+
|
203 |
+
concatf:<URL>
|
204 |
+
|
205 |
+
where URL is the url containing a line break delimited list of
|
206 |
+
resources to be concatenated, each one possibly specifying a distinct
|
207 |
+
protocol. Special characters must be escaped with backslash or single
|
208 |
+
quotes. See the "Quoting and escaping" section in the ffmpeg-utils(1)
|
209 |
+
manual.
|
210 |
+
|
211 |
+
For example to read a sequence of files split1.mpeg, split2.mpeg,
|
212 |
+
split3.mpeg listed in separate lines within a file split.txt with
|
213 |
+
ffplay use the command:
|
214 |
+
|
215 |
+
ffplay concatf:split.txt
|

For example, to convert a GIF file given inline with ffmpeg:
|
244 |
+
|
245 |
+
ffmpeg -i "data:image/gif;base64,R0lGODdhCAAIAMIEAAAAAAAA//8AAP//AP///////////////ywAAAAACAAIAAADF0gEDLojDgdGiJdJqUX02iB4E8Q9jUMkADs=" smiley.png
|
246 |
+
|
247 |
+
fd
|
248 |
+
File descriptor access protocol.
|
249 |
+
|
250 |
+
The accepted syntax is:
|
251 |
+
|
252 |
+
fd: -fd <file_descriptor>
|
253 |
+
|
254 |
+
If fd is not specified, by default the stdout file descriptor will be
|
255 |
+
used for writing, stdin for reading. Unlike the pipe protocol, fd
|
256 |
+
protocol has seek support if it corresponding to a regular file. fd
|
257 |
+
protocol doesn't support pass file descriptor via URL for security.
|
258 |
+
|
259 |
+
This protocol accepts the following options:
|
260 |
+
|
261 |
+
blocksize
|
262 |
+
Set I/O operation maximum block size, in bytes. Default value is
|
263 |
+
"INT_MAX", which results in not limiting the requested block size.
|
264 |
+
Setting this value reasonably low improves user termination request
|
265 |
+
reaction time, which is valuable if data transmission is slow.
|
266 |
+
|
267 |
+
fd Set file descriptor.
|
268 |
+
|
269 |
+
file
|
270 |
+
File access protocol.
|
271 |
+
|
272 |
+
Read from or write to a file.
|
273 |
+
|
274 |
+
A file URL can have the form:
|
275 |
+
|
276 |
+
file:<filename>
|
277 |
+
|
278 |
+
where filename is the path of the file to read.
|
279 |
+
|
280 |
+
An URL that does not have a protocol prefix will be assumed to be a
|
281 |
+
file URL. Depending on the build, an URL that looks like a Windows path
|
282 |
+
with the drive letter at the beginning will also be assumed to be a
|
283 |
+
file URL (usually not the case in builds for unix-like systems).
|
284 |
+
|
285 |
+
For example to read from a file input.mpeg with ffmpeg use the command:
|
286 |
+
|
287 |
+
ffmpeg -i file:input.mpeg output.mpeg
|
288 |
+
|
289 |
+
This protocol accepts the following options:
|
290 |
+
|
291 |
+
truncate
|
292 |
+
Truncate existing files on write, if set to 1. A value of 0
|
293 |
+
prevents truncating. Default value is 1.
|
294 |
+
|
295 |
+
blocksize
|
296 |
+
Set I/O operation maximum block size, in bytes. Default value is
|
297 |
+
"INT_MAX", which results in not limiting the requested block size.
|
298 |
+
Setting this value reasonably low improves user termination request
|
299 |
+
reaction time, which is valuable for files on slow medium.
|
300 |
+
|
301 |
+
follow
|
302 |
+
If set to 1, the protocol will retry reading at the end of the
|
303 |
+
file, allowing reading files that still are being written. In order
|
304 |
+
for this to terminate, you either need to use the rw_timeout
|
305 |
+
option, or use the interrupt callback (for API users).
|
306 |
+
|
307 |
+
seekable
|
308 |
+
Controls if seekability is advertised on the file. 0 means non-
|
309 |
+
seekable, -1 means auto (seekable for normal files, non-seekable
|
310 |
+
for named pipes).
|
311 |
+
|
312 |
+
Many demuxers handle seekable and non-seekable resources
|
313 |
+
differently, overriding this might speed up opening certain files
|
314 |
+
at the cost of losing some features (e.g. accurate seeking).
|
315 |
+
|
316 |
+
ftp
|
317 |
+
FTP (File Transfer Protocol).
|
318 |
+
|
319 |
+
Read from or write to remote resources using FTP protocol.
|
320 |
+
|
321 |
+
Following syntax is required.
|
322 |
+
|
323 |
+
ftp://[user[:password]@]server[:port]/path/to/remote/resource.mpeg
|
324 |
+
|
325 |
+
This protocol accepts the following options.
|
326 |
+
|
327 |
+
timeout
|
328 |
+
Set timeout in microseconds of socket I/O operations used by the
|
329 |
+
underlying low level operation. By default it is set to -1, which
|
330 |
+
means that the timeout is not specified.
|
331 |
+
|
332 |
+
ftp-user
|
333 |
+
Set a user to be used for authenticating to the FTP server. This is
|
334 |
+
overridden by the user in the FTP URL.
|
335 |
+
|
336 |
+
ftp-password
|
337 |
+
Set a password to be used for authenticating to the FTP server.
|
338 |
+
This is overridden by the password in the FTP URL, or by ftp-
|
339 |
+
anonymous-password if no user is set.
|
340 |
+
|
341 |
+
ftp-anonymous-password
|
342 |
+
Password used when login as anonymous user. Typically an e-mail
|
343 |
+
address should be used.
|
344 |
+
|
345 |
+
ftp-write-seekable
|
346 |
+
Control seekability of connection during encoding. If set to 1 the
|
347 |
+
resource is supposed to be seekable, if set to 0 it is assumed not
|
348 |
+
to be seekable. Default value is 0.
|
349 |
+
|
350 |
+
NOTE: Protocol can be used as output, but it is recommended to not do
|
351 |
+
it, unless special care is taken (tests, customized server
|
352 |
+
configuration etc.). Different FTP servers behave in different way
|
353 |
+
during seek operation. ff* tools may produce incomplete content due to
|
354 |
+
server limitations.
|
355 |
+
|
356 |
+
gopher
|
357 |
+
Gopher protocol.

+
hls
|
365 |
+
Read Apple HTTP Live Streaming compliant segmented stream as a uniform
|
366 |
+
one. The M3U8 playlists describing the segments can be remote HTTP
|
367 |
+
resources or local files, accessed using the standard file protocol.
|
368 |
+
The nested protocol is declared by specifying "+proto" after the hls
|
369 |
+
URI scheme name, where proto is either "file" or "http".
|
370 |
+
|
371 |
+
hls+http://host/path/to/remote/resource.m3u8
|
372 |
+
hls+file://path/to/local/resource.m3u8
|
373 |
+
|
374 |
+
Using this protocol is discouraged - the hls demuxer should work just
|
375 |
+
as well (if not, please report the issues) and is more complete. To
|
376 |
+
use the hls demuxer instead, simply use the direct URLs to the m3u8
|
377 |
+
files.
|
378 |
+
|
379 |
+
http
|
380 |

This protocol accepts the following options:
|
383 |
+
|
384 |
+
seekable
|
385 |
+
Control seekability of connection. If set to 1 the resource is
|
386 |
+
supposed to be seekable, if set to 0 it is assumed not to be
|
387 |
+
seekable, if set to -1 it will try to autodetect if it is seekable.
|
388 |
+
Default value is -1.
|
389 |
+
|
390 |
+
chunked_post
|

+
request.
|
413 |
+
|
414 |
+
user_agent
|
415 |
+
Override the User-Agent header. If not specified the protocol will
|
416 |
+
use a string describing the libavformat build. ("Lavf/<version>")
|
417 |
+
|
418 |
+
reconnect_at_eof
|
419 |
+
If set then eof is treated like an error and causes reconnection,
|
420 |

this is useful for live / endless streams.
|
421 |
+
|
422 |
+
reconnect_streamed

|
442 |
+
Exports the HTTP response version number. Usually "1.0" or "1.1".
|
443 |
+
|
444 |
+
icy If set to 1 request ICY (SHOUTcast) metadata from the server. If
|
445 |
+
the server supports this, the metadata has to be retrieved by the
|
446 |
+
application by reading the icy_metadata_headers and
|
447 |
+
icy_metadata_packet options. The default is 1.
|
448 |
+
|
449 |
+
icy_metadata_headers
|
450 |
+
If the server supports ICY metadata, this contains the ICY-specific
|

HTTP reply headers, separated by newline characters.
|
452 |
+
|
453 |
+
icy_metadata_packet
|
454 |
+
If the server supports ICY metadata, and icy was set to 1, this
|
455 |
+
contains the last non-empty metadata packet sent by the server. It
|
456 |
+
should be polled in regular intervals by applications interested in
|
457 |
+
mid-stream metadata updates.
|
458 |
+
|
459 |
+
cookies
|
460 |
+
Set the cookies to be sent in future requests. The format of each
|
461 |
+
cookie is the same as the value of a Set-Cookie HTTP response
|
462 |
+
field. Multiple cookies can be delimited by a newline character.
|
463 |
+
|
464 |
+
offset

+
Set initial byte offset.
|
466 |
+
|
467 |
+
end_offset
|
468 |
+
Try to limit the request to bytes preceding this offset.
|
469 |
+
|
470 |
+
method
|
471 |
+
When used as a client option it sets the HTTP method for the
|
472 |
+
request.
|
473 |
+
|
474 |
+
When used as a server option it sets the HTTP method that is going
|
475 |
+
to be expected from the client(s). If the expected and the
|
476 |
+
received HTTP method do not match the client will be given a Bad
|
477 |
+
Request response. When unset the HTTP method is not checked for
|
478 |
+
now. This will be replaced by autodetection in the future.
|
479 |
+
|
480 |
+
listen
|
481 |
+
If set to 1 enables experimental HTTP server. This can be used to
|
482 |
+
send data when used as an output option, or read data from a client
|
483 |
+
with HTTP POST when used as an input option. If set to 2 enables
|
484 |
+
experimental multi-client HTTP server. This is not yet implemented
|
485 |
+
in ffmpeg.c and thus must not be used as a command line option.
|

|
504 |
+
|
505 |
+
send_expect_100
|
506 |
+
Send an Expect: 100-continue header for POST. If set to 1 it will
|
507 |
+
send, if set to 0 it won't, if set to -1 it will try to send if it
|
508 |
+
is applicable. Default value is -1.
|
509 |
+
|
510 |
+
auth_type
|
511 |
+
Set HTTP authentication type. No option for Digest, since this
|
512 |
+
method requires getting nonce parameters from the server first and
|
513 |
+
can't be used straight away like Basic.
|
514 |
+
|
515 |
+
none
|
516 |
+
Choose the HTTP authentication type automatically. This is the
|
517 |
+
default.
|
518 |
+
|
519 |
+
basic
|
520 |
+
Choose the HTTP basic authentication.
|
521 |
+
|
522 |
+
Basic authentication sends a Base64-encoded string that
|
523 |
+
contains a user name and password for the client. Base64 is not
|
524 |
+
a form of encryption and should be considered the same as
|
525 |
+
sending the user name and password in clear text (Base64 is a
|
526 |
+
reversible encoding). If a resource needs to be protected,
|
527 |
+
strongly consider using an authentication scheme other than
|
528 |
+
basic authentication. HTTPS/TLS should be used with basic
|
529 |
+
authentication. Without these additional security
|
530 |
+
enhancements, basic authentication should not be used to
|
531 |
+
protect sensitive or valuable information.
|
532 |
+
|
533 |
+
HTTP Cookies
|
534 |
+
|
535 |
+
Some HTTP requests will be denied unless cookie values are passed in
|
536 |
+
with the request. The cookies option allows these cookies to be
|
537 |
+
specified. At the very least, each cookie must specify a value along
|
538 |
+
with a path and domain. HTTP requests that match both the domain and
|
539 |
+
path will automatically include the cookie value in the HTTP Cookie
|
540 |
+
header field. Multiple cookies can be delimited by a newline.
|
541 |
+
|
542 |
+
The required syntax to play a stream specifying a cookie is:
|
543 |
+
|
544 |
+
ffplay -cookies "nlqptid=nltid=tsn; path=/; domain=somedomain.com;" http://somedomain.com/somestream.m3u8
|

546 |
+
Icecast
|
547 |
+
Icecast protocol (stream to Icecast servers)
|
548 |
+
|
549 |
+
This protocol accepts the following options:
|
550 |
+
|
551 |
+
ice_genre
|
552 |
+
Set the stream genre.
|
553 |
+
|
554 |
+
ice_name
|
555 |
+
Set the stream name.
|
556 |
+
|
557 |
+
ice_description
|
558 |
+
Set the stream description.
|
559 |
+
|
560 |
+
ice_url
|
561 |
+
Set the stream website URL.
|
562 |
+
|
563 |
+
ice_public
|
564 |
+
Set if the stream should be public. The default is 0 (not public).
|
565 |
+
|
566 |
+
user_agent
|
567 |
+
Override the User-Agent header. If not specified a string of the
|
568 |
+
form "Lavf/<version>" will be used.
|
569 |
+
|
570 |
+
password
|
571 |
+
Set the Icecast mountpoint password.
|
572 |
+
|
573 |
+
content_type
|
574 |
+
Set the stream content type. This must be set if it is different
|
575 |
+
from audio/mpeg.
|
576 |
+
|
577 |
+
legacy_icecast
|
578 |
+
This enables support for Icecast versions < 2.4.0, that do not
|
579 |
+
support the HTTP PUT method but the SOURCE method.
|
580 |
+
|
581 |
+
tls Establish a TLS (HTTPS) connection to Icecast.
|
582 |
+
|
583 |
+
icecast://[<username>[:<password>]@]<server>:<port>/<mountpoint>
|
584 |
+
|
585 |
+
ipfs
|
586 |
+
InterPlanetary File System (IPFS) protocol support. One can access
|
587 |
+
files stored on the IPFS network through so-called gateways. These are
|
588 |
+
http(s) endpoints. This protocol wraps the IPFS native protocols
|
589 |
+
(ipfs:// and ipns://) to be sent to such a gateway. Users can (and
|
590 |
+
should) host their own node which means this protocol will use one's
|
591 |
+
local gateway to access files on the IPFS network.
|
592 |
+
|
593 |
+
This protocol accepts the following options:
|
594 |
+
|
595 |
+
gateway
|
596 |
+
Defines the gateway to use. When not set, the protocol will first
|
597 |
+
try locating the local gateway by looking at $IPFS_GATEWAY,
|
598 |
+
$IPFS_PATH and "$HOME/.ipfs/", in that order.
|
599 |
+
|
600 |
+
One can use this protocol in 2 ways. Using IPFS:
|
601 |
+
|
602 |
+
ffplay ipfs://<hash>
|
603 |
+
|
604 |
+
Or the IPNS protocol (IPNS is mutable IPFS):
|
605 |
+
|
606 |
+
ffplay ipns://<hash>
|
607 |
+
|
608 |
+
mmst
|
609 |
+
MMS (Microsoft Media Server) protocol over TCP.
|
610 |
+
|
611 |
+
mmsh
|
612 |
+
MMS (Microsoft Media Server) protocol over HTTP.
|
613 |
+
|
614 |
+
The required syntax is:
|
615 |
+
|
616 |
+
mmsh://<server>[:<port>][/<app>][/<playpath>]
|
617 |
+
|
618 |
+
md5
|
619 |
+
MD5 output protocol.
|
620 |
+
|
621 |
+
Computes the MD5 hash of the data to be written, and on close writes
|
622 |
+
this to the designated output or stdout if none is specified. It can be
|
623 |
+
used to test muxers without writing an actual file.
|
624 |
+
|
625 |
+
Some examples follow.
|
626 |
+
|
627 |
+
# Write the MD5 hash of the encoded AVI file to the file output.avi.md5.
|
628 |
+
ffmpeg -i input.flv -f avi -y md5:output.avi.md5
|
629 |
+
|
630 |
+
# Write the MD5 hash of the encoded AVI file to stdout.
|
631 |
+
ffmpeg -i input.flv -f avi -y md5:
|
632 |
+
|
633 |
+
Note that some formats (typically MOV) require the output protocol to
|
634 |
+
be seekable, so they will fail with the MD5 output protocol.
|
635 |
+
|
636 |
+
pipe
|
637 |
+
UNIX pipe access protocol.
|
638 |
+
|
639 |
+
Read and write from UNIX pipes.
|
640 |
+
|
641 |
+
The accepted syntax is:
|
642 |
+
|
643 |
+
pipe:[<number>]
|
644 |
+
|
645 |
+
If fd isn't specified, number is the number corresponding to the file
|
646 |
+
descriptor of the pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr).
|
647 |
+
If number is not specified, by default the stdout file descriptor will
|
648 |
+
be used for writing, stdin for reading.
|
649 |
+
|
650 |
+
For example to read from stdin with ffmpeg:
|
651 |
+
|
652 |
+
cat test.wav | ffmpeg -i pipe:0
|
653 |
+
# ...this is the same as...
|
654 |
+
cat test.wav | ffmpeg -i pipe:
|
655 |
+
|
656 |
+
For writing to stdout with ffmpeg:
|
657 |
+
|
658 |
+
ffmpeg -i test.wav -f avi pipe:1 | cat > test.avi
|
659 |
+
# ...this is the same as...
|
660 |
+
ffmpeg -i test.wav -f avi pipe: | cat > test.avi
|
661 |
+
|
662 |
+
This protocol accepts the following options:
|
663 |
+
|
664 |
+
blocksize
|
665 |
+
Set I/O operation maximum block size, in bytes. Default value is
|
666 |
+
"INT_MAX", which results in not limiting the requested block size.
|
667 |
+
Setting this value reasonably low improves user termination request
|
668 |
+
reaction time, which is valuable if data transmission is slow.
|
669 |
+
|
670 |
+
fd Set file descriptor.
|
671 |
+
|
672 |
+
Note that some formats (typically MOV), require the output protocol to
|
673 |
+
be seekable, so they will fail with the pipe output protocol.
|
674 |
+
|
675 |
+
prompeg
|
676 |
+
Pro-MPEG Code of Practice #3 Release 2 FEC protocol.
|
677 |
+
|
678 |
+
The Pro-MPEG CoP#3 FEC is a 2D parity-check forward error correction
|
679 |
+
mechanism for MPEG-2 Transport Streams sent over RTP.
|
680 |
+
|
681 |
+
This protocol must be used in conjunction with the "rtp_mpegts" muxer
|
682 |
+
and the "rtp" protocol.
|
683 |
+
|
684 |
+
The required syntax is:
|
685 |
+
|
686 |
+
-f rtp_mpegts -fec prompeg=<option>=<val>... rtp://<hostname>:<port>
|
687 |
+
|
688 |
+
The destination UDP ports are "port + 2" for the column FEC stream and
|
689 |
+
"port + 4" for the row FEC stream.
|
690 |
+
|
691 |
+
This protocol accepts the following options:
|
692 |
+
|
693 |
+
l=n The number of columns (4-20, LxD <= 100)
|
694 |
+
|
695 |
+
d=n The number of rows (4-20, LxD <= 100)
|
696 |
+
|
697 |
+
Example usage:
|
698 |
+
|
699 |
+
-f rtp_mpegts -fec prompeg=l=8:d=4 rtp://<hostname>:<port>

|
732 |
+
if you explicitly want to enable debug level messages or packet
|
733 |
+
loss simulation, otherwise the regular loglevel is respected.
|

app It is the name of the application to access. It usually corresponds
|
767 |
+
to the path where the application is installed on the RTMP server
|
768 |
+
(e.g. /ondemand/, /flash/live/, etc.). You can override the value

must be 0 or 1 to end or begin an object, respectively. Data items
|
801 |
+
in subobjects may be named, by prefixing the type with 'N' and
|
802 |
+
specifying the name before the value (i.e. "NB:myFlag:1"). This
|
803 |
+
option may be used multiple times to construct arbitrary AMF

+
rtmp_live
|
816 |
+
Specify that the media is a live stream. No resuming or seeking in
|
817 |
+
live streams is possible. The default value is "any", which means
|
818 |
+
the subscriber first tries to play the live stream specified in the
|
819 |
+
playpath. If a live stream of that name is not found, it plays the
|
820 |

|
841 |
+
|
842 |
+
rtmp_swfurl
|
843 |

+
Set TCP_NODELAY to disable Nagle's algorithm. Default value is 0.
|
854 |
+
|
855 |
+
Remark: Writing to the socket is currently not optimized to
|
856 |

"--enable-librtmp". If enabled this will replace the native RTMP
|
964 |
+
protocol.
|
965 |

|
966 |
+
This protocol provides most client functions and a few server functions
|
967 |

needed to support RTMP, RTMP tunneled in HTTP (RTMPT), encrypted RTMP
|
968 |
+
(RTMPE), RTMP over SSL/TLS (RTMPS) and tunneled variants of these
|
969 |
+
encrypted types (RTMPTE, RTMPTS).
|
970 |
+
|
971 |
+
The required syntax is:
|
972 |
+
|
973 |
+
<rtmp_proto>://<server>[:<port>][/<app>][/<playpath>] <options>
|
974 |
+
|
975 |
+
where rtmp_proto is one of the strings "rtmp", "rtmpt", "rtmpe",
|
976 |
+
"rtmps", "rtmpte", "rtmpts" corresponding to each RTMP variant, and
|
977 |
+
server, port, app and playpath have the same meaning as specified for
|
978 |
+
the RTMP native protocol. options contains a list of space-separated
|
979 |
+
options of the form key=val.
|
980 |

rtsp
|
1058 |
+
Real-Time Streaming Protocol.
|
1059 |
+
|
1060 |
+
RTSP is not technically a protocol handler in libavformat, it is a
|
1061 |
+
demuxer and muxer. The demuxer supports both normal RTSP (with data
|
1062 |
+
transferred over RTP; this is used by e.g. Apple and Microsoft) and
|
1063 |
+
Real-RTSP (with data transferred over RDT).
|
1064 |
+
|
1065 |
+
The muxer can be used to send a stream using RTSP ANNOUNCE to a server
|
1066 |
+
supporting it (currently Darwin Streaming Server and Mischa
|
1067 |
+
Spiegelmock's <https://github.com/revmischa/rtsp-server>).
|
1068 |
+
|
1069 |
+
The required syntax for a RTSP url is:
|
1070 |
+
|
1071 |
+
rtsp://<hostname>[:<port>]/<path>
|
1072 |
+
|
1073 |
+
Options can be set on the ffmpeg/ffplay command line, or set in code
|
1074 |
+
via "AVOption"s or in "avformat_open_input".

|
1156 |
+
Multiple lower transport protocols may be specified, in that case
|
1157 |
+
they are tried one at a time (if the setup of one fails, the next
|

|
1203 |
+
connection. Setting listen_timeout > 0 sets rtsp_flags to listen.
|
1204 |
+

|
1219 |
+
|
1220 |
+
When receiving data over UDP, the demuxer tries to reorder received
|
1221 |
+
packets (since they may arrive out of order, or packets may get lost
|
1222 |
+
totally). This can be disabled by setting the maximum demuxing delay to
|
1223 |
+
zero (via the "max_delay" field of AVFormatContext).
|
1224 |
+
|
1225 |
+
When watching multi-bitrate Real-RTSP streams with ffplay, the streams
|
1226 |
+
to display can be chosen with "-vst" n and "-ast" n for video and audio
|
1227 |
+
respectively, and can be switched on the fly by pressing "v" and "a".
|
1228 |
+
|
1229 |
+
Examples
|
1230 |
+
|
1231 |
+
The following examples all make use of the ffplay and ffmpeg tools.
|
1232 |
+
|
1233 |

Session Announcement Protocol (RFC 2974). This is not technically a
|
1252 |
+
protocol handler in libavformat, it is a muxer and demuxer. It is used
|
1253 |
+
for signalling of RTP streams, by announcing the SDP for the streams
|
1254 |
+
regularly on a separate port.
|
1255 |
+
|
1256 |
+
Muxer
|
1257 |
+
|
1258 |
+
The syntax for a SAP url given to the muxer is:
|
1259 |
+
|
1260 |
+
sap://<destination>[:<port>][?<options>]
|
1261 |
+
|
1262 |
+
The RTP packets are sent to destination on port port, or to port 5004
|
1263 |
+
if no port is specified. options is a "&"-separated list. The
|
1264 |
+
following options are supported:
|
1265 |
+
|
1266 |
+
announce_addr=address
|
1267 |
+
Specify the destination IP address for sending the announcements
|
1268 |
+
to. If omitted, the announcements are sent to the commonly used
|
1269 |
+
SAP announcement multicast address 224.2.127.254 (sap.mcast.net),
|
1270 |
+
or ff0e::2:7ffe if destination is an IPv6 address.
|
1271 |
+
|
1272 |
+
announce_port=port
|
1273 |
+
Specify the port to send the announcements on, defaults to 9875 if
|
1274 |
+
not specified.
|
1275 |
+
|
1276 |
+
ttl=ttl
|
1277 |
+
Specify the time to live value for the announcements and RTP
|
1278 |
+
packets, defaults to 255.
|
1279 |
+
|
1280 |
+
same_port=0|1
|
1281 |
+
If set to 1, send all RTP streams on the same port pair. If zero
|
1282 |
+
(the default), all streams are sent on unique ports, with each
|
1283 |
+
stream on a port 2 numbers higher than the previous. VLC/Live555
|
1284 |
+
requires this to be set to 1, to be able to receive the stream.
|
1285 |
+
The RTP stack in libavformat for receiving requires all streams to
|
1286 |
+
be sent on unique ports.
|
1287 |
+
|
1288 |
+
Example command lines follow.
|
1289 |
+
|
1290 |
+
To broadcast a stream on the local subnet, for watching in VLC:
|
1291 |
+
|
1292 |
+
ffmpeg -re -i <input> -f sap sap://224.0.0.255?same_port=1
|
1293 |
+
|
1294 |
+
Similarly, for watching in ffplay:
|
1295 |
+
|
1296 |
+
ffmpeg -re -i <input> -f sap sap://224.0.0.255
|
1297 |
+
|
1298 |
+
And for watching in ffplay, over IPv6:
|
1299 |
+
|
1300 |
+
ffmpeg -re -i <input> -f sap sap://[ff0e::1:2:3:4]
|
1301 |
+
|
1302 |
+
Demuxer
|
1303 |
+
|
1304 |
+
The syntax for a SAP url given to the demuxer is:
|
1305 |
+
|
1306 |
+
sap://[<address>][:<port>]
|
1307 |
+
|
1308 |
+
address is the multicast address to listen for announcements on, if
|
1309 |
+
omitted, the default 224.2.127.254 (sap.mcast.net) is used. port is the
|
1310 |
+
port that is listened on, 9875 if omitted.
|
1311 |
+
|
1312 |
+
The demuxers listens for announcements on the given address and port.
|
1313 |
+
Once an announcement is received, it tries to receive that particular
|
1314 |
+
stream.
|
1315 |
+
|
1316 |
+
Example command lines follow.
|
1317 |
+
|
1318 |
+
To play back the first stream announced on the normal SAP multicast
|
1319 |
+
address:
|
1320 |
+
|
1321 |
+
ffplay sap://
|
1322 |
+
|
1323 |
+
To play back the first stream announced on one the default IPv6 SAP
|
1324 |
+
multicast address:
|
1325 |
+
|
1326 |
+
ffplay sap://[ff0e::2:7ffe]
|
1327 |
+
|
1328 |
+
sctp
|
1329 |
+
Stream Control Transmission Protocol.
|
1330 |
+
|
1331 |
+
The accepted URL syntax is:
|
1332 |
+
|
1333 |
+
sctp://<host>:<port>[?<options>]
|
1334 |
+
|
1335 |
+
The protocol accepts the following options:
|
1336 |
+
|
1337 |
+
listen
|
1338 |
+
If set to any value, listen for an incoming connection. Outgoing
|
1339 |
+
connection is done by default.
|
1340 |
+
|
1341 |
+
max_streams
|
1342 |
+
Set the maximum number of streams. By default no limit is set.
|
1343 |
+
|
1344 |
+
srt
|
1345 |
+
Haivision Secure Reliable Transport Protocol via libsrt.
|
1346 |
+
|
1347 |
+
The supported syntax for a SRT URL is:
|
1348 |
+
|
1349 |
+
srt://<hostname>:<port>[?<options>]
|
1350 |
+
|
1351 |
+
options contains a list of &-separated options of the form key=val.
|
1352 |
+
|
1353 |
+
or
|
1354 |
+
|
1355 |
+
<options> srt://<hostname>:<port>
|
1356 |
+
|
1357 |
+
options contains a list of '-key val' options.
|
1358 |
+
|
1359 |
+
This protocol accepts the following options.
|
1360 |
+
|
1361 |
+
connect_timeout=milliseconds
|
1362 |
+
Connection timeout; SRT cannot connect for RTT > 1500 msec (2
|
1363 |
+
handshake exchanges) with the default connect timeout of 3 seconds.
|
1364 |
+
This option applies to the caller and rendezvous connection modes.
|
1365 |
+
The connect timeout is 10 times the value set for the rendezvous
|
1366 |
+
mode (which can be used as a workaround for this connection problem
|
1367 |
+
with earlier versions).
|
1368 |
+
|
1369 |
+
ffs=bytes
|
1370 |
+
Flight Flag Size (Window Size), in bytes. FFS is actually an
|
1371 |
+
internal parameter and you should set it to not less than
|
1372 |
+
recv_buffer_size and mss. The default value is relatively large,
|
1373 |
+
therefore unless you set a very large receiver buffer, you do not
|
1374 |
+
need to change this option. Default value is 25600.
|
1375 |
+
|
1376 |
+
inputbw=bytes/seconds
|
1377 |
+
Sender nominal input rate, in bytes per seconds. Used along with
|
1378 |
+
oheadbw, when maxbw is set to relative (0), to calculate maximum
|
1379 |
+
sending rate when recovery packets are sent along with the main
|
1380 |
+
media stream: inputbw * (100 + oheadbw) / 100 if inputbw is not set
|
1381 |
+
while maxbw is set to relative (0), the actual input rate is
|
1382 |
+
evaluated inside the library. Default value is 0.
|
1383 |
+
|
1384 |
+
iptos=tos
|
1385 |
+
IP Type of Service. Applies to sender only. Default value is 0xB8.
|
1386 |
+
|
1387 |
+
ipttl=ttl
|
1388 |
+
IP Time To Live. Applies to sender only. Default value is 64.
|
1389 |
+
|
1390 |
+
latency=microseconds
|
1391 |
+
Timestamp-based Packet Delivery Delay. Used to absorb bursts of
|
1392 |
+
missed packet retransmissions. This flag sets both rcvlatency and
|
1393 |
+
peerlatency to the same value. Note that prior to version 1.3.0
|
1394 |
+
this is the only flag to set the latency, however this is
|
1395 |
+
effectively equivalent to setting peerlatency, when side is sender
|
1396 |
+
and rcvlatency when side is receiver, and the bidirectional stream
|
1397 |
+
sending is not supported.
|
1398 |
+
|
1399 |
+
listen_timeout=microseconds
|
1400 |
+
Set socket listen timeout.
|
1401 |
+
|
1402 |
+
maxbw=bytes/seconds
|
1403 |
+
Maximum sending bandwidth, in bytes per seconds. -1 infinite
|
1404 |
+
(CSRTCC limit is 30mbps) 0 relative to input rate (see inputbw) >0
|
1405 |
+
absolute limit value Default value is 0 (relative)
|
1406 |
+
|
1407 |
+
mode=caller|listener|rendezvous
|
1408 |
+
Connection mode. caller opens client connection. listener starts
|
1409 |
+
server to listen for incoming connections. rendezvous use Rendez-
|
1410 |
+
Vous connection mode. Default value is caller.
|
1411 |
+
|
1412 |
+
mss=bytes
|
1413 |
+
Maximum Segment Size, in bytes. Used for buffer allocation and rate
|
1414 |
+
calculation using a packet counter assuming fully filled packets.
|
1415 |
+
The smallest MSS between the peers is used. This is 1500 by default
|
1416 |
+
in the overall internet. This is the maximum size of the UDP
|
1417 |
+
packet and can be only decreased, unless you have some unusual
|
1418 |
+
dedicated network settings. Default value is 1500.
|
1419 |
+
|
1420 |
+
nakreport=1|0
|
1421 |
+
If set to 1, Receiver will send `UMSG_LOSSREPORT` messages
|
1422 |
+
periodically until a lost packet is retransmitted or intentionally
|
1423 |
+
dropped. Default value is 1.
|
1424 |
+
|
1425 |
+
oheadbw=percents
|
1426 |
+
Recovery bandwidth overhead above input rate, in percents. See
|
1427 |
+
inputbw. Default value is 25%.
|
1428 |
+
|
1429 |
+
passphrase=string
|
1430 |
+
HaiCrypt Encryption/Decryption Passphrase string, length from 10 to
|
1431 |
+
79 characters. The passphrase is the shared secret between the
|
1432 |
+
sender and the receiver. It is used to generate the Key Encrypting
|
1433 |
+
Key using PBKDF2 (Password-Based Key Derivation Function). It is
|
1434 |
+
used only if pbkeylen is non-zero. It is used on the receiver only
|
1435 |
+
if the received data is encrypted. The configured passphrase
|
1436 |
+
cannot be recovered (write-only).
|
1437 |
+
|
1438 |
+
enforced_encryption=1|0
|
1439 |
+
If true, both connection parties must have the same password set
|
1440 |
+
(including empty, that is, with no encryption). If the password
|
1441 |
+
doesn't match or only one side is unencrypted, the connection is
|
1442 |
+
rejected. Default is true.
|
1443 |
+
|
1444 |
+
kmrefreshrate=packets
|
1445 |
+
The number of packets to be transmitted after which the encryption
|
1446 |
+
key is switched to a new key. Default is -1. -1 means auto
|
1447 |
+
(0x1000000 in srt library). The range for this option is integers
|
1448 |
+
in the 0 - "INT_MAX".
|
1449 |
+
|
1450 |
+
kmpreannounce=packets
|
1451 |
+
The interval between when a new encryption key is sent and when
|
1452 |
+
switchover occurs. This value also applies to the subsequent
|
1453 |
+
interval between when switchover occurs and when the old encryption
|
1454 |
+
key is decommissioned. Default is -1. -1 means auto (0x1000 in srt
|
1455 |
+
library). The range for this option is integers in the 0 -
|
1456 |
+
"INT_MAX".
|
1457 |
+
|
1458 |
+
snddropdelay=microseconds
|
1459 |
+
The sender's extra delay before dropping packets. This delay is
|
1460 |
+
added to the default drop delay time interval value.
|
1461 |
+
|
1462 |
+
Special value -1: Do not drop packets on the sender at all.
|
1463 |
+
|
1464 |
+
payload_size=bytes
|
1465 |
+
Sets the maximum declared size of a packet transferred during the
|
1466 |
+
single call to the sending function in Live mode. Use 0 if this
|
1467 |
+
value isn't used (which is default in file mode). Default is -1
|
1468 |
+
(automatic), which typically means MPEG-TS; if you are going to use
|
1469 |
+
SRT to send any different kind of payload, such as, for example,
|
1470 |
+
wrapping a live stream in very small frames, then you can use a
|
1471 |
+
bigger maximum frame size, though not greater than 1456 bytes.
|
1472 |
+
|
1473 |
+
pkt_size=bytes
|
1474 |
+
Alias for payload_size.
|
1475 |
+
|
1476 |
+
peerlatency=microseconds
|
1477 |
+
The latency value (as described in rcvlatency) that is set by the
|
1478 |
+
sender side as a minimum value for the receiver.
|
1479 |
+
|
1480 |
+
pbkeylen=bytes
|
1481 |
+
Sender encryption key length, in bytes. Only can be set to 0, 16,
|
1482 |
+
24 and 32. Enable sender encryption if not 0. Not required on
|
1483 |
+
receiver (set to 0), key size obtained from sender in HaiCrypt
|
1484 |
+
handshake. Default value is 0.
|
1485 |
+
|
1486 |
+
rcvlatency=microseconds
|
1487 |
+
The time that should elapse since the moment when the packet was
|
1488 |
+
sent and the moment when it's delivered to the receiver application
|
1489 |
+
in the receiving function. This time should be a buffer time large
|
1490 |
+
enough to cover the time spent for sending, unexpectedly extended
|
1491 |
+
RTT time, and the time needed to retransmit the lost UDP packet.
|
1492 |
+
The effective latency value will be the maximum of this options'
|
1493 |
+
value and the value of peerlatency set by the peer side. Before
|
1494 |
+
version 1.3.0 this option is only available as latency.
|
1495 |
+
|
1496 |
+
recv_buffer_size=bytes
|
1497 |
+
Set UDP receive buffer size, expressed in bytes.
|
1498 |
+
|
1499 |
+
send_buffer_size=bytes
|
1500 |
+
Set UDP send buffer size, expressed in bytes.
|
1501 |
+
|
1502 |
+
timeout=microseconds
|
1503 |
+
Set raise error timeouts for read, write and connect operations.
|
1504 |
+
Note that the SRT library has internal timeouts which can be
|
1505 |
+
controlled separately, the value set here is only a cap on those.
|
1506 |
+
|
1507 |
+
tlpktdrop=1|0
|
1508 |
+
Too-late Packet Drop. When enabled on receiver, it skips missing
|
1509 |
+
packets that have not been delivered in time and delivers the
|
1510 |
+
following packets to the application when their time-to-play has
|
1511 |
+
come. It also sends a fake ACK to the sender. When enabled on
|
1512 |
+
sender and enabled on the receiving peer, the sender drops the
|
1513 |
+
older packets that have no chance of being delivered in time. It
|
1514 |
+
was automatically enabled in the sender if the receiver supports
|
1515 |
+
it.
|
1516 |
+
|
1517 |
+
sndbuf=bytes
|
1518 |
+
Set send buffer size, expressed in bytes.
|
1519 |
+
|
1520 |
+
rcvbuf=bytes
|
1521 |
+
Set receive buffer size, expressed in bytes.
|
1522 |
+
|
1523 |
+
Receive buffer must not be greater than ffs.
|
1524 |
+
|
1525 |
+
lossmaxttl=packets
|
1526 |
+
The value up to which the Reorder Tolerance may grow. When Reorder
|
1527 |
+
Tolerance is > 0, then packet loss report is delayed until that
|
1528 |
+
number of packets come in. Reorder Tolerance increases every time a
|
1529 |
+
"belated" packet has come, but it wasn't due to retransmission
|
1530 |
+
(that is, when UDP packets tend to come out of order), with the
|
1531 |
+
difference between the latest sequence and this packet's sequence,
|
1532 |
+
and not more than the value of this option. By default it's 0,
|
1533 |
+
which means that this mechanism is turned off, and the loss report
|
1534 |
+
is always sent immediately upon experiencing a "gap" in sequences.
|
1535 |
+
|
1536 |
+
minversion
|
1537 |
+
The minimum SRT version that is required from the peer. A
|
1538 |
+
connection to a peer that does not satisfy the minimum version
|
1539 |
+
requirement will be rejected.
|
1540 |
+
|
1541 |
+
The version format in hex is 0xXXYYZZ for x.y.z in human readable
|
1542 |
+
form.
|
1543 |
+
|
1544 |
+
streamid=string
|
1545 |
+
A string limited to 512 characters that can be set on the socket
|
1546 |
+
prior to connecting. This stream ID will be able to be retrieved by
|
1547 |
+
the listener side from the socket that is returned from srt_accept
|
1548 |
+
and was connected by a socket with that set stream ID. SRT does not
|
1549 |
+
enforce any special interpretation of the contents of this string.
|
1550 |
+
This option doesnXt make sense in Rendezvous connection; the result
|
1551 |
+
might be that simply one side will override the value from the
|
1552 |
+
other side and itXs the matter of luck which one would win
|
1553 |
+
|
1554 |
+
srt_streamid=string
|
1555 |
+
Alias for streamid to avoid conflict with ffmpeg command line
|
1556 |
+
option.
|
1557 |
+
|
1558 |
+
smoother=live|file
|
1559 |
+
The type of Smoother used for the transmission for that socket,
|
1560 |
+
which is responsible for the transmission and congestion control.
|
1561 |
+
The Smoother type must be exactly the same on both connecting
|
1562 |
+
parties, otherwise the connection is rejected.
|
1563 |
+
|
1564 |
+
messageapi=1|0
|
1565 |
+
When set, this socket uses the Message API, otherwise it uses
|
1566 |
+
Buffer API. Note that in live mode (see transtype) thereXs only
|
1567 |
+
message API available. In File mode you can chose to use one of two
|
1568 |
+
modes:
|
1569 |
+
|
1570 |
+
Stream API (default, when this option is false). In this mode you
|
1571 |
+
may send as many data as you wish with one sending instruction, or
|
1572 |
+
even use dedicated functions that read directly from a file. The
|
1573 |
+
internal facility will take care of any speed and congestion
|
1574 |
+
control. When receiving, you can also receive as many data as
|
1575 |
+
desired, the data not extracted will be waiting for the next call.
|
1576 |
+
There is no boundary between data portions in the Stream mode.
|
1577 |
+
|
1578 |
+
Message API. In this mode your single sending instruction passes
|
1579 |
+
exactly one piece of data that has boundaries (a message). Contrary
|
1580 |
+
to Live mode, this message may span across multiple UDP packets and
|
1581 |
+
the only size limitation is that it shall fit as a whole in the
|
1582 |
+
sending buffer. The receiver shall use as large buffer as necessary
|
1583 |
+
to receive the message, otherwise the message will not be given up.
|
1584 |
+
When the message is not complete (not all packets received or there
|
1585 |
+
was a packet loss) it will not be given up.
|
1586 |
+
|
1587 |
+
transtype=live|file
|
1588 |
+
Sets the transmission type for the socket, in particular, setting
|
1589 |
+
this option sets multiple other parameters to their default values
|
1590 |
+
as required for a particular transmission type.
|
1591 |
+
|
1592 |
+
live: Set options as for live transmission. In this mode, you
|
1593 |
+
should send by one sending instruction only so many data that fit
|
1594 |
+
in one UDP packet, and limited to the value defined first in
|
1595 |
+
payload_size (1316 is default in this mode). There is no speed
|
1596 |
+
control in this mode, only the bandwidth control, if configured, in
|
1597 |
+
order to not exceed the bandwidth with the overhead transmission
|
1598 |
+
(retransmitted and control packets).
|
1599 |
+
|
1600 |
+
file: Set options as for non-live transmission. See messageapi for
|
1601 |
+
further explanations
|
1602 |
+
|
1603 |
+
linger=seconds
|
1604 |
+
The number of seconds that the socket waits for unsent data when
|
1605 |
+
closing. Default is -1. -1 means auto (off with 0 seconds in live
|
1606 |
+
mode, on with 180 seconds in file mode). The range for this option
|
1607 |
+
is integers in the 0 - "INT_MAX".
|
1608 |
+
|
1609 |
+
tsbpd=1|0
|
1610 |
+
When true, use Timestamp-based Packet Delivery mode. The default
|
1611 |
+
behavior depends on the transmission type: enabled in live mode,
|
1612 |
+
disabled in file mode.

tcp
|
1672 |
+
Transmission Control Protocol.
|
1673 |
+
|
1674 |
+
The required syntax for a TCP url is:
|
1675 |
+
|
1676 |
+
tcp://<hostname>:<port>[?<options>]
|
1677 |
+
|
1678 |
+
options contains a list of &-separated options of the form key=val.
|
1679 |
+
|
1680 |
+
The list of supported options follows.
|
1681 |
+
|
1682 |
+
listen=2|1|0
|
1683 |
+
Listen for an incoming connection. 0 disables listen, 1 enables
|
1684 |
+
listen in single client mode, 2 enables listen in multi-client
|
1685 |
+
mode. Default value is 0.
|
1686 |
+
|
1687 |
+
timeout=microseconds
|
1688 |
+
Set raise error timeout, expressed in microseconds.
|
1689 |
+
|
1690 |
+
This option is only relevant in read mode: if no data arrived in
|
1691 |
+
more than this time interval, raise error.
|
1692 |
+
|
1693 |
+
listen_timeout=milliseconds
|
1694 |
+
Set listen timeout, expressed in milliseconds.
|
1695 |
+
|
1696 |
+
recv_buffer_size=bytes
|
1697 |
+
Set receive buffer size, expressed bytes.
|
1698 |
+
|
1699 |
+
send_buffer_size=bytes
|
1700 |
+
Set send buffer size, expressed bytes.
|
1701 |
+
|
1702 |
+
tcp_nodelay=1|0
|
1703 |
+
Set TCP_NODELAY to disable Nagle's algorithm. Default value is 0.
|
1704 |
+
|
1705 |
+
Remark: Writing to the socket is currently not optimized to
|
1706 |
+
minimize system calls and reduces the efficiency / effect of
|
1707 |
+
TCP_NODELAY.
|
1708 |
+
|
1709 |
+
tcp_mss=bytes
|
1710 |
+
Set maximum segment size for outgoing TCP packets, expressed in
|
1711 |
+
bytes.
|
1712 |
+
|
1713 |
+
The following example shows how to setup a listening TCP connection
|
1714 |
+
with ffmpeg, which is then accessed with ffplay:
|
1715 |
+
|
1716 |
+
ffmpeg -i <input> -f <format> tcp://<hostname>:<port>?listen
|
1717 |
+
ffplay tcp://<hostname>:<port>
|
1718 |
+
|
1719 |
+
tls
|
1720 |
+
Transport Layer Security (TLS) / Secure Sockets Layer (SSL)
|
1721 |
+
|
1722 |
+
The required syntax for a TLS/SSL url is:
|
1723 |
+
|
1724 |
+
tls://<hostname>:<port>[?<options>]
|
1725 |
+
|
1726 |
+
The following parameters can be set via command line options (or in
|
1727 |
+
code via "AVOption"s):
|
1728 |
+
|
1729 |
+
ca_file, cafile=filename
|
1730 |
+
A file containing certificate authority (CA) root certificates to
|
1731 |
+
treat as trusted. If the linked TLS library contains a default this
|
1732 |
+
might not need to be specified for verification to work, but not
|
1733 |
+
all libraries and setups have defaults built in. The file must be
|
1734 |
+
in OpenSSL PEM format.
|
1735 |
+
|
1736 |
+
tls_verify=1|0
|
1737 |
+
If enabled, try to verify the peer that we are communicating with.
|
1738 |
+
Note, if using OpenSSL, this currently only makes sure that the
|
1739 |
+
peer certificate is signed by one of the root certificates in the
|
1740 |
+
CA database, but it does not validate that the certificate actually
|
1741 |
+
matches the host name we are trying to connect to. (With other
|
1742 |
+
backends, the host name is validated as well.)
|
1743 |
+
|
1744 |
+
This is disabled by default since it requires a CA database to be
|
1745 |
+
provided by the caller in many cases.
|
1746 |
+
|
1747 |
+
cert_file, cert=filename
|
1748 |
+
A file containing a certificate to use in the handshake with the
|
1749 |
+
peer. (When operating as server, in listen mode, this is more
|
1750 |
+
often required by the peer, while client certificates only are
|
1751 |
+
mandated in certain setups.)
|
1752 |
+
|
1753 |
+
key_file, key=filename
|
1754 |
+
A file containing the private key for the certificate.
|
1755 |
+
|
1756 |
+
listen=1|0
|
1757 |
+
If enabled, listen for connections on the provided port, and assume
|
1758 |
+
the server role in the handshake instead of the client role.
|
1759 |
+
|
1760 |
+
http_proxy
|
1761 |
+
The HTTP proxy to tunnel through, e.g. "http://example.com:1234".
|
1762 |
+
The proxy must support the CONNECT method.
|
1763 |
+
|
1764 |
+
Example command lines:
|
1765 |
+
|
1766 |
+
To create a TLS/SSL server that serves an input stream.
|
1767 |
+
|
1768 |
+
ffmpeg -i <input> -f <format> tls://<hostname>:<port>?listen&cert=<server.crt>&key=<server.key>
|
1769 |
+
|
1770 |
+
To play back a stream from the TLS/SSL server using ffplay:
|
1771 |
+
|
1772 |
+
ffplay tls://<hostname>:<port>
|
1773 |
+
|
1774 |
+
udp
|
1775 |
+
User Datagram Protocol.
|
1776 |
+
|
1777 |
+
The required syntax for an UDP URL is:
|
1778 |
+
|
1779 |
+
udp://<hostname>:<port>[?<options>]
|
1780 |
+
|
1781 |
+
options contains a list of &-separated options of the form key=val.
|
1782 |
+
|
1783 |
+
In case threading is enabled on the system, a circular buffer is used
|
1784 |
+
to store the incoming data, which allows one to reduce loss of data due
|
1785 |
+
to UDP socket buffer overruns. The fifo_size and overrun_nonfatal
|
1786 |
+
options are related to this buffer.
|
1787 |
+
|
1788 |
+
The list of supported options follows.
|
1789 |
+
|
1790 |
+
buffer_size=size
|
1791 |
+
Set the UDP maximum socket buffer size in bytes. This is used to
|
1792 |
+
set either the receive or send buffer size, depending on what the
|
1793 |
+
socket is used for. Default is 32 KB for output, 384 KB for input.
|
1794 |
+
See also fifo_size.
|
1795 |
+
|
1796 |
+
bitrate=bitrate
|
1797 |
+
If set to nonzero, the output will have the specified constant
|
1798 |
+
bitrate if the input has enough packets to sustain it.
|
1799 |
+
|
1800 |
+
burst_bits=bits
|
1801 |
+
When using bitrate this specifies the maximum number of bits in
|
1802 |
+
packet bursts.
|
1803 |
+
|
1804 |
+
localport=port
|
1805 |
+
Override the local UDP port to bind with.
|
1806 |
+
|
1807 |
+
localaddr=addr
|
1808 |
+
Local IP address of a network interface used for sending packets or
|
1809 |
+
joining multicast groups.
|
1810 |
+
|
1811 |
+
pkt_size=size
|
1812 |
+
Set the size in bytes of UDP packets.
|
1813 |
+
|
1814 |
+
reuse=1|0
|
1815 |
+
Explicitly allow or disallow reusing UDP sockets.
|
1816 |
+
|
1817 |
+
ttl=ttl
|
1818 |
+
Set the time to live value (for multicast only).
|
1819 |
+
|
1820 |
+
connect=1|0
|
1821 |
+
Initialize the UDP socket with "connect()". In this case, the
|
1822 |
+
destination address can't be changed with ff_udp_set_remote_url
|
1823 |
+
later. If the destination address isn't known at the start, this
|
1824 |
+
option can be specified in ff_udp_set_remote_url, too. This allows
|
1825 |
+
finding out the source address for the packets with getsockname,
|
1826 |
+
and makes writes return with AVERROR(ECONNREFUSED) if "destination
|
1827 |
+
unreachable" is received. For receiving, this gives the benefit of
|
1828 |
+
only receiving packets from the specified peer address/port.
|
1829 |
+
|
1830 |
+
sources=address[,address]
|
1831 |
+
Only receive packets sent from the specified addresses. In case of
|
1832 |
+
multicast, also subscribe to multicast traffic coming from these
|
1833 |
+
addresses only.
|
1834 |
+
|
1835 |
+
block=address[,address]
|
1836 |
+
Ignore packets sent from the specified addresses. In case of
|
1837 |
+
multicast, also exclude the source addresses in the multicast
|
1838 |
+
subscription.
|
1839 |
+
|
1840 |
+
fifo_size=units
|
1841 |
+
Set the UDP receiving circular buffer size, expressed as a number
|
1842 |
+
of packets with size of 188 bytes. If not specified defaults to
|
1843 |
+
7*4096.
|
1844 |
+
|
1845 |
+
overrun_nonfatal=1|0
|
1846 |
+
Survive in case of UDP receiving circular buffer overrun. Default
|
1847 |
+
value is 0.
|
1848 |
+
|
1849 |
+
timeout=microseconds
|
1850 |
+
Set raise error timeout, expressed in microseconds.
|
1851 |
+
|
1852 |
+
This option is only relevant in read mode: if no data arrived in
|
1853 |
+
more than this time interval, raise error.
|
1854 |
+
|
1855 |
+
broadcast=1|0
|
1856 |
+
Explicitly allow or disallow UDP broadcasting.
|
1857 |
+
|
1858 |
+
Note that broadcasting may not work properly on networks having a
|
1859 |
+
broadcast storm protection.
|
1860 |
+
|
1861 |
+
Examples
|
1862 |
+
|
1863 |
+
o Use ffmpeg to stream over UDP to a remote endpoint:
|
1864 |
+
|
1865 |
+
ffmpeg -i <input> -f <format> udp://<hostname>:<port>
|
1866 |
+
|
1867 |
+
o Use ffmpeg to stream in mpegts format over UDP using 188 sized UDP
|
1868 |
+
packets, using a large input buffer:
|
1869 |
+
|
1870 |
+
ffmpeg -i <input> -f mpegts udp://<hostname>:<port>?pkt_size=188&buffer_size=65535
|
1871 |
+
|
1872 |
+
o Use ffmpeg to receive over UDP from a remote endpoint:
|
1873 |
+
|
1874 |
+
ffmpeg -i udp://[<multicast-address>]:<port> ...
|
1875 |
+
|
1876 |
+
unix
|
1877 |
+
Unix local socket
|
1878 |
+
|
1879 |
+
The required syntax for a Unix socket URL is:
|
1880 |
+
|
1881 |
+
unix://<filepath>
|
1882 |
+
|
1883 |
+
The following parameters can be set via command line options (or in
|
1884 |
+
code via "AVOption"s):
|
1885 |
+
|
1886 |
+
timeout
|
1887 |
+
Timeout in ms.
|
1888 |
+
|
1889 |
+
listen
|
1890 |
+
Create the Unix socket in listening mode.
|
1891 |
+
|
1892 |
+
zmq
|
1893 |
+
ZeroMQ asynchronous messaging using the libzmq library.
|
1894 |
+
|
1895 |
+
This library supports unicast streaming to multiple clients without
|
1896 |
+
relying on an external server.
|
1897 |
+
|
1898 |
+
The required syntax for streaming or connecting to a stream is:
|
1899 |
+
|
1900 |
+
zmq:tcp://ip-address:port
|
1901 |
+
|
1902 |
+
Example: Create a localhost stream on port 5555:
|
1903 |
+
|
1904 |
+
ffmpeg -re -i input -f mpegts zmq:tcp://127.0.0.1:5555
|
1905 |
+
|
1906 |
+
Multiple clients may connect to the stream using:
|
1907 |
+
|
1908 |
+
ffplay zmq:tcp://127.0.0.1:5555
|
1909 |
+
|
1910 |
+
Streaming to multiple clients is implemented using a ZeroMQ Pub-Sub
|
1911 |
+
pattern. The server side binds to a port and publishes data. Clients
|
1912 |
+
connect to the server (via IP address/port) and subscribe to the
|
1913 |
+
stream. The order in which the server and client start generally does
|
1914 |
+
not matter.
|
1915 |
+
|
1916 |
+
ffmpeg must be compiled with the --enable-libzmq option to support this
|
1917 |
+
protocol.
|
1918 |
+
|
1919 |
+
Options can be set on the ffmpeg/ffplay command line. The following
|
1920 |
+
options are supported:
|
1921 |
+
|
1922 |
+
pkt_size
|
1923 |
+
Forces the maximum packet size for sending/receiving data. The
|
1924 |
+
default value is 131,072 bytes. On the server side, this sets the
|
1925 |
+
maximum size of sent packets via ZeroMQ. On the clients, it sets an
|
1926 |
+
internal buffer size for receiving packets. Note that pkt_size on
|
1927 |
+
the clients should be equal to or greater than pkt_size on the
|
1928 |
+
server. Otherwise the received message may be truncated causing
|
1929 |
+
decoding errors.

NAME
|
4 |
+
ffmpeg-resampler - FFmpeg Resampler
|
5 |
+
|
6 |
+
DESCRIPTION
|
7 |
+
The FFmpeg resampler provides a high-level interface to the
|
8 |
+
libswresample library audio resampling utilities. In particular it
|
9 |
+
allows one to perform audio resampling, audio channel layout
|
10 |
+
rematrixing, and convert audio format and packing layout.
|
11 |
+
|
12 |
+
RESAMPLER OPTIONS
|
13 |
+
The audio resampler supports the following named options.
|
14 |
+
|
15 |
+
Options may be set by specifying -option value in the FFmpeg tools,
|
16 |
+
option=value for the aresample filter, by setting the value explicitly
|
17 |
+
in the "SwrContext" options or using the libavutil/opt.h API for
|
18 |
+
programmatic use.
|
19 |
+
|
20 |
+
uchl, used_chlayout
|
21 |
+
Set used input channel layout. Default is unset. This option is
|
22 |
+
only used for special remapping.
|
23 |
+
|
24 |
+
isr, in_sample_rate
|
25 |
+
Set the input sample rate. Default value is 0.
|
26 |
+
|
27 |
+
osr, out_sample_rate
|
28 |
+
Set the output sample rate. Default value is 0.
|
29 |
+
|
30 |
+
isf, in_sample_fmt
|
31 |
+
Specify the input sample format. It is set by default to "none".
|
32 |
+
|
33 |
+
osf, out_sample_fmt
|
34 |
+
Specify the output sample format. It is set by default to "none".
|
35 |
+
|
36 |
+
tsf, internal_sample_fmt
|
37 |
+
Set the internal sample format. Default value is "none". This will
|
38 |
+
automatically be chosen when it is not explicitly set.
|
39 |
+
|
40 |
+
ichl, in_chlayout
|
41 |
+
ochl, out_chlayout
|
42 |
+
Set the input/output channel layout.
|
43 |
+
|
44 |
+
See the Channel Layout section in the ffmpeg-utils(1) manual for
|
45 |
+
the required syntax.
|
46 |
+
|
47 |
+
clev, center_mix_level
|
48 |
+
Set the center mix level. It is a value expressed in deciBel, and
|
49 |
+
must be in the interval [-32,32].
|
50 |
+
|
51 |
+
slev, surround_mix_level
|
52 |
+
Set the surround mix level. It is a value expressed in deciBel, and
|
53 |
+
must be in the interval [-32,32].
|
54 |
+
|
55 |
+
lfe_mix_level
|
56 |
+
Set LFE mix into non LFE level. It is used when there is a LFE
|
57 |
+
input but no LFE output. It is a value expressed in deciBel, and
|
58 |
+
must be in the interval [-32,32].
|
59 |
+
|
60 |
+
rmvol, rematrix_volume
|
61 |
+
Set rematrix volume. Default value is 1.0.
|
62 |
+
|
63 |
+
rematrix_maxval
|
64 |
+
Set maximum output value for rematrixing. This can be used to
|
65 |
+
prevent clipping vs. preventing volume reduction. A value of 1.0
|
66 |
+
prevents clipping.
|
67 |
+
|
68 |
+
flags, swr_flags
|
69 |
+
Set flags used by the converter. Default value is 0.
|
70 |
+
|
71 |
+
It supports the following individual flags:
|
72 |
+
|
73 |
+
res force resampling, this flag forces resampling to be used even
|
74 |
+
when the input and output sample rates match.
|
75 |
+
|
76 |
+
dither_scale
|
77 |
+

+
resampler
|
115 |
+
Set resampling engine. Default value is swr.
|
116 |
+
|
117 |
+
Supported values:
|
118 |
+
|
119 |
+
swr select the native SW Resampler; filter options precision and
|
120 |
+
cheby are not applicable in this case.
|
121 |
+
|
122 |
+
soxr
|
123 |
+
select the SoX Resampler (where available); compensation, and
|
124 |
+
filter options filter_size, phase_shift, exact_rational,
|
125 |
+
filter_type & kaiser_beta, are not applicable in this case.
|
126 |
+
|
127 |
+
filter_size
|
128 |
+
For swr only, set resampling filter size, default value is 32.
|
129 |
+
|
130 |
+
phase_shift
|
131 |
+
For swr only, set resampling phase shift, default value is 10, and
|
132 |
+
must be in the interval [0,30].
|
133 |
+
|
134 |
+
linear_interp
|
135 |
+
Use linear interpolation when enabled (the default). Disable it if
|
136 |
+
you want to preserve speed instead of quality when exact_rational
|
137 |
+
fails.
|
138 |
+
|
139 |
+
exact_rational
|
140 |
+
For swr only, when enabled, try to use exact phase_count based on
|
141 |
+
input and output sample rate. However, if it is larger than "1 <<
|
142 |
+
phase_shift", the phase_count will be "1 << phase_shift" as
|
143 |
+
fallback. Default is enabled.
|
144 |
+
|
145 |
+
cutoff
|
146 |
+
Set cutoff frequency (swr: 6dB point; soxr: 0dB point) ratio; must
|
147 |
+
be a float value between 0 and 1. Default value is 0.97 with swr,
|
148 |
+
and 0.91 with soxr (which, with a sample-rate of 44100, preserves
|
149 |
+
the entire audio band to 20kHz).
|
150 |
+
|
151 |
+
precision
|
152 |
+
For soxr only, the precision in bits to which the resampled signal
|
153 |
+
will be calculated. The default value of 20 (which, with suitable
|
154 |
+
dithering, is appropriate for a destination bit-depth of 16) gives
|
155 |
+
SoX's 'High Quality'; a value of 28 gives SoX's 'Very High
|
156 |
+
Quality'.
|
157 |
+
|
158 |
+
cheby
|
159 |
+
For soxr only, selects passband rolloff none (Chebyshev) & higher-
|
160 |
+
precision approximation for 'irrational' ratios. Default value is
|
161 |
+
0.
|
162 |
+
|
163 |
+
async
|
164 |
+
For swr only, simple 1 parameter audio sync to timestamps using
|
165 |
+
stretching, squeezing, filling and trimming. Setting this to 1 will
|
166 |
+
enable filling and trimming, larger values represent the maximum
|
167 |
+
amount in samples that the data may be stretched or squeezed for
|
168 |
+
each second. Default value is 0, thus no compensation is applied
|
169 |
+
to make the samples match the audio timestamps.
|
170 |
+
|
171 |
+
first_pts
|
172 |
+
For swr only, assume the first pts should be this value. The time
|
173 |
+
unit is 1 / sample rate. This allows for padding/trimming at the
|
174 |
+
start of stream. By default, no assumption is made about the first
|
175 |
+
frame's expected pts, so no padding or trimming is done. For
|
176 |
+
example, this could be set to 0 to pad the beginning with silence
|
177 |
+
if an audio stream starts after the video stream or to trim any
|
178 |
+
samples with a negative pts due to encoder delay.
|
179 |
+
|
180 |
+
min_comp
|
181 |
+
For swr only, set the minimum difference between timestamps and
|
182 |
+
audio data (in seconds) to trigger stretching/squeezing/filling or
|
183 |
+
trimming of the data to make it match the timestamps. The default
|
184 |
+
is that stretching/squeezing/filling and trimming is disabled
|
185 |
+
(min_comp = "FLT_MAX").
|
186 |
+
|
187 |
+
min_hard_comp
|
188 |
+
For swr only, set the minimum difference between timestamps and
|
189 |
+
audio data (in seconds) to trigger adding/dropping samples to make
|
190 |
+
it match the timestamps. This option effectively is a threshold to
|
191 |
+
select between hard (trim/fill) and soft (squeeze/stretch)
|
192 |
+
compensation. Note that all compensation is by default disabled
|
193 |
+
through min_comp. The default is 0.1.
|
194 |
+
|
195 |
+
comp_duration
|
196 |
+
For swr only, set duration (in seconds) over which data is
|
197 |
+
stretched/squeezed to make it match the timestamps. Must be a non-
|
198 |
+
negative double float value, default value is 1.0.
|
199 |
+
|
200 |
+
max_soft_comp
|
201 |
+
For swr only, set maximum factor by which data is
|
202 |
+
stretched/squeezed to make it match the timestamps. Must be a non-
|
203 |
+
negative double float value, default value is 0.
|
204 |
+
|
205 |
+
matrix_encoding
|
206 |
+
Select matrixed stereo encoding.
|
207 |
+

|
209 |
+
|
210 |
+
none
|
211 |
+
select none
|
212 |

|
216 |
+
dplii

|
218 |
+
|
219 |
+
Default value is "none".
|
220 |
+
|
221 |
+
filter_type
|
222 |
+
For swr only, select resampling filter type. This only affects
|
223 |
+
resampling operations.
|
224 |
+
|
225 |
+
It accepts the following values:
|
226 |

|
233 |
+
kaiser
|
234 |
+
select Kaiser windowed sinc
|
235 |
+
|
236 |
+
kaiser_beta
|
237 |
+
For swr only, set Kaiser window beta value. Must be a double float
|
238 |
+
value in the interval [2,16], default value is 9.
|
239 |
+
|
240 |
+
output_sample_bits
|
241 |
+
For swr only, set number of used output sample bits for dithering.
|
242 |
+
Must be an integer in the interval [0,64], default value is 0,
|
243 |
+
which means it's not used.

+
ffmpeg-scaler - FFmpeg video scaling and pixel format converter
|
5 |
+
|
6 |
+
DESCRIPTION
|
7 |
+
The FFmpeg rescaler provides a high-level interface to the libswscale
|
8 |
+
library image conversion utilities. In particular it allows one to
|
9 |
+
perform image rescaling and pixel format conversion.
|
10 |
+
|
11 |
+
SCALER OPTIONS
|
12 |
+
The video scaler supports the following named options.
|
13 |
+
|
14 |
+
Options may be set by specifying -option value in the FFmpeg tools,
|
15 |
+
with a few API-only exceptions noted below. For programmatic use, they
|
16 |
+
can be set explicitly in the "SwsContext" options or through the
|
17 |
+
libavutil/opt.h API.
|
18 |
+
|
19 |
+
sws_flags
|
20 |
+

DESCRIPTION
|
7 |
+
This document describes some generic features and utilities provided by
|
8 |
+
the libavutil library.
|
9 |
+
|
10 |
+
SYNTAX
|
11 |
+
This section documents the syntax and formats employed by the FFmpeg
|
12 |
+
libraries and tools.
|
13 |
+
|
14 |
+
Quoting and escaping
|
15 |
+
FFmpeg adopts the following quoting and escaping mechanism, unless
|
16 |
+
explicitly specified. The following rules are applied:
|
17 |
+
|
18 |
+
o ' and \ are special characters (respectively used for quoting and
|
19 |
+
escaping). In addition to them, there might be other special
|
20 |
+
characters depending on the specific syntax where the escaping and
|
21 |
+
quoting are employed.
|
22 |
+
|
23 |
+
o A special character is escaped by prefixing it with a \.
|
24 |
+
|
25 |
+
o All characters enclosed between '' are included literally in the
|
26 |
+
parsed string. The quote character ' itself cannot be quoted, so
|
27 |
+
you may need to close the quote and escape it.
|
28 |
+
|
29 |
+
o Leading and trailing whitespaces, unless escaped or quoted, are
|
30 |
+
removed from the parsed string.
|
31 |
+
|
32 |
+
Note that you may need to add a second level of escaping when using the
|
33 |
+
command line or a script, which depends on the syntax of the adopted
|
34 |
+
shell language.
|
35 |
+
|
36 |
+
The function "av_get_token" defined in libavutil/avstring.h can be used
|
37 |
+
to parse a token quoted or escaped according to the rules defined
|
38 |
+
above.
|
39 |
+
|
40 |
+
The tool tools/ffescape in the FFmpeg source tree can be used to
|
41 |
+
automatically quote or escape a string in a script.
|
42 |
+
|
43 |
+
Examples
|
44 |
+
|
45 |
+
o Escape the string "Crime d'Amour" containing the "'" special
|
46 |
+
character:
|
47 |
+
|
48 |
+
Crime d\'Amour
|
49 |
+
|
50 |
+
o The string above contains a quote, so the "'" needs to be escaped
|
51 |
+
when quoting it:
|
52 |
+
|
53 |
+
'Crime d'\''Amour'
|
54 |
+
|
55 |
+
o Include leading or trailing whitespaces using quoting:
|
56 |
+
|
57 |
+
' this string starts and ends with whitespaces '
|
58 |
+
|
59 |
+
o Escaping and quoting can be mixed together:
|
60 |
+
|
61 |
+
' The string '\'string\'' is a string '
|
62 |
+
|
63 |
+
o To include a literal \ you can use either escaping or quoting:
|
64 |
+
|
65 |
+
'c:\foo' can be written as c:\\foo
|
66 |
+
|
67 |
+
Date
|
68 |
+
The accepted syntax is:
|
69 |
+
|
70 |
+
[(YYYY-MM-DD|YYYYMMDD)[T|t| ]]((HH:MM:SS[.m...]]])|(HHMMSS[.m...]]]))[Z]
|
71 |
+
now
|
72 |
+
|
73 |
+
If the value is "now" it takes the current time.
|
74 |
+
|
75 |
+
Time is local time unless Z is appended, in which case it is
|
76 |
+
interpreted as UTC. If the year-month-day part is not specified it
|
77 |
+
takes the current year-month-day.
|
78 |
+
|
79 |
+
Time duration
|
80 |
+
There are two accepted syntaxes for expressing time duration.
|
81 |
+
|
82 |
+
[-][<HH>:]<MM>:<SS>[.<m>...]
|
83 |
+
|
84 |
+
HH expresses the number of hours, MM the number of minutes for a
|
85 |
+
maximum of 2 digits, and SS the number of seconds for a maximum of 2
|
86 |
+
digits. The m at the end expresses decimal value for SS.
|
87 |
+
|
88 |
+
or
|
89 |
+
|
90 |
+
[-]<S>+[.<m>...][s|ms|us]
|
91 |
+
|
92 |
+
S expresses the number of seconds, with the optional decimal part m.
|
93 |
+
The optional literal suffixes s, ms or us indicate to interpret the
|
94 |
+
value as seconds, milliseconds or microseconds, respectively.
|
95 |
+
|
96 |
+
In both expressions, the optional - indicates negative duration.
|
97 |
+
|
98 |
+
Examples
|
99 |
+
|
100 |
+
The following examples are all valid time duration:
|
101 |
+
|
102 |
+
55 55 seconds
|
103 |
+
|
104 |
+
0.2 0.2 seconds
|
105 |
+
|
106 |
+
200ms
|
107 |
+
200 milliseconds, that's 0.2s
|
108 |
+
|
109 |
+
200000us
|
110 |
+
200000 microseconds, that's 0.2s
|
111 |
+
|
112 |
+
12:03:45
|
113 |
+
12 hours, 03 minutes and 45 seconds
|
114 |
+
|
115 |
+
23.189
|
116 |
+
23.189 seconds
|
117 |
+
|
118 |
+
Video size
|
119 |
+
Specify the size of the sourced video, it may be a string of the form
|
120 |
+
widthxheight, or the name of a size abbreviation.

A ratio can be expressed as an expression, or in the form
|
306 |
+
numerator:denominator.
|
307 |
+
|
308 |
+
Note that a ratio with infinite (1/0) or negative value is considered
|

valid, so you should check on the returned value if you want to exclude
|
310 |
+
those values.
|
311 |
+
|
312 |
+
The undefined value can be expressed using the "0:0" string.
|
313 |
+
|
314 |
+
Color
|
315 |
+
It can be the name of a color as defined below (case insensitive match)
|
316 |
+
or a "[0x|#]RRGGBB[AA]" sequence, possibly followed by @ and a string
|
317 |
+
representing the alpha component.
|
318 |
+
|
319 |
+
The alpha component may be a string composed by "0x" followed by an
|
320 |
+
hexadecimal number or a decimal number between 0.0 and 1.0, which
|
321 |
+
represents the opacity value (0x00 or 0.0 means completely transparent,
|
322 |
+
0xff or 1.0 completely opaque). If the alpha component is not specified
|
323 |
+
then 0xff is assumed.
|
324 |
+
|
325 |
+
The string random will result in a random color.

Channel Layout
|
748 |
+
A channel layout specifies the spatial disposition of the channels in a
|
749 |
+
multi-channel audio stream. To specify a channel layout, FFmpeg makes
|
750 |
+
use of a special syntax.
|
751 |
+
|
752 |
+
Individual channels are identified by an id, as given by the table
|
753 |
+

A custom channel layout can be specified as a sequence of terms,
|
891 |
+
separated by '+'. Each term can be:
|
892 |
+
|
893 |
+
o the name of a single channel (e.g. FL, FR, FC, LFE, etc.), each
|
894 |
+
optionally containing a custom name after a '@', (e.g. FL@Left,
|
895 |
+
FR@Right, FC@Center, LFE@Low_Frequency, etc.)
|
896 |
+
|
897 |
+
A standard channel layout can be specified by the following:
|
898 |
+
|
899 |
+
o the name of a single channel (e.g. FL, FR, FC, LFE, etc.)
|
900 |
+
|
901 |
+
o the name of a standard channel layout (e.g. mono, stereo, 4.0,
|
902 |
+
quad, 5.0, etc.)
|
903 |
+
|
904 |
+
o a number of channels, in decimal, followed by 'c', yielding the
|
905 |
+
default channel layout for that number of channels (see the
|
906 |
+
function "av_channel_layout_default"). Note that not all channel
|
907 |
+
counts have a default layout.
|
908 |
+
|
909 |
+
o a number of channels, in decimal, followed by 'C', yielding an
|
910 |
+
unknown channel layout with the specified number of channels. Note
|
911 |
+
that not all channel layout specification strings support unknown
|
912 |
+
channel layouts.
|
913 |
+
|
914 |
+
o a channel layout mask, in hexadecimal starting with "0x" (see the
|
915 |
+
"AV_CH_*" macros in libavutil/channel_layout.h.
|
916 |
+
|
917 |
+
Before libavutil version 53 the trailing character "c" to specify a
|
918 |
+
number of channels was optional, but now it is required, while a
|
919 |
+
channel layout mask can also be specified as a decimal number (if and
|
920 |
+
only if not followed by "c" or "C").
|
921 |
+
|
922 |
+
See also the function "av_channel_layout_from_string" defined in
|
923 |
+
libavutil/channel_layout.h.
|
924 |
+
|
925 |
+
EXPRESSION EVALUATION
|
926 |
+
When evaluating an arithmetic expression, FFmpeg uses an internal
|
927 |
+
formula evaluator, implemented through the libavutil/eval.h interface.
|
928 |
+
|
929 |
+
An expression may contain unary, binary operators, constants, and
|
930 |
+
functions.
|
931 |
+
|
932 |
+
Two expressions expr1 and expr2 can be combined to form another
|
933 |
+
expression "expr1;expr2". expr1 and expr2 are evaluated in turn, and
|
934 |
+
the new expression evaluates to the value of expr2.
|
935 |
+
|
936 |
+
The following binary operators are available: "+", "-", "*", "/", "^".
|
937 |
+
|
938 |
+
The following unary operators are available: "+", "-".
|
939 |
+
|
940 |
+
The following functions are available:
|
941 |
+
|
942 |

before executing the bitwise operation.
|
967 |
+
|
968 |
+
Note that both the conversion to integer and the conversion back to
|
969 |

+
When the series does not converge the result is undefined.
|
1132 |
+
|
1133 |
+
ld(id) is used to represent the derivative order in expr, which
|
1134 |
+
means that the given expression will be evaluated multiple times
|
1135 |

The following constants are available:
|
1154 |
+
|
1155 |
+
PI area of the unit disc, approximately 3.14
|
1156 |
+
|
1157 |
+
E exp(1) (Euler's number), approximately 2.718
|
1158 |
+
|
1159 |
+
PHI golden ratio (1+sqrt(5))/2, approximately 1.618
|
1160 |
+
|
1161 |
+
Assuming that an expression is considered "true" if it has a non-zero
|
1162 |
+
value, note that:
|
1163 |
+
|
1164 |
+
"*" works like AND
|
1165 |
+
|
1166 |
+
"+" works like OR
|
1167 |
+
|
1168 |
+
For example the construct:
|
1169 |
+
|
1170 |
+
if (A AND B) then C
|
1171 |
+
|
1172 |
+
is equivalent to:
|
1173 |
+
|
1174 |
+
if(A*B, C)
|
1175 |
+
|
1176 |
+
In your C code, you can extend the list of unary and binary functions,
|
1177 |
+
and define recognized constants, so that they are available for your
|
1178 |
+
expressions.
|
1179 |
+
|
1180 |
+
The evaluator also recognizes the International System unit prefixes.
|
1181 |
+
If 'i' is appended after the prefix, binary prefixes are used, which
|
1182 |
+
are based on powers of 1024 instead of powers of 1000. The 'B' postfix
|
1183 |
+
multiplies the value by 8, and can be appended after a unit prefix or
|
1184 |
+
used alone. This allows using for example 'KB', 'MiB', 'G' and 'B' as
|
1185 |
+
number postfix.
|
1186 |
+
|
1187 |
+
The list of available International System prefixes follows, with
|
1188 |
+
indication of the corresponding powers of 10 and of 2.

DESCRIPTION
|
10 |
+
ffprobe gathers information from multimedia streams and prints it in
|
11 |
+
human- and machine-readable fashion.
|
12 |
+
|
13 |
+
For example it can be used to check the format of the container used by
|
14 |
+
a multimedia stream and the format and type of each media stream
|
15 |
+
contained in it.
|
16 |
+
|
17 |
+
If a url is specified in input, ffprobe will try to open and probe the
|
18 |
+
url content. If the url cannot be opened or recognized as a multimedia
|
19 |
+
file, a positive exit code is returned.
|
20 |
+
|
21 |
+
If no output is specified as output with o ffprobe will write to
|
22 |
+
stdout.
|
23 |
+
|
24 |
+
ffprobe may be employed both as a standalone application or in
|
25 |
+
combination with a textual filter, which may perform more sophisticated
|
26 |
+
processing, e.g. statistical processing or plotting.
|
27 |
+
|
28 |
+
Options are used to list some of the formats supported by ffprobe or
|
29 |
+
for specifying which information to display, and for setting how
|
30 |
+
ffprobe will show it.
|
31 |
+
|
32 |
+
ffprobe output is designed to be easily parsable by a textual filter,
|
33 |
+
and consists of one or more sections of a form defined by the selected
|
34 |
+
writer, which is specified by the print_format option.
|
35 |
+
|
36 |
+
Sections may contain other nested sections, and are identified by a
|
37 |
+
name (which may be shared by other sections), and an unique name. See
|
38 |
+
the output of sections.
|
39 |
+
|
40 |
+
Metadata tags stored in the container or in the streams are recognized
|
41 |
+
and printed in the corresponding "FORMAT", "STREAM" or "PROGRAM_STREAM"
|
42 |
+
section.
|
43 |
+
|
44 |
+
OPTIONS
|
45 |
+
All the numerical options, if not specified otherwise, accept a string
|
46 |
+
representing a number as input, which may be followed by one of the SI
|
47 |
+
unit prefixes, for example: 'K', 'M', or 'G'.
|
48 |
+
|
49 |
+
If 'i' is appended to the SI unit prefix, the complete prefix will be
|
50 |
+
interpreted as a unit prefix for binary multiples, which are based on
|
51 |
+
powers of 1024 instead of powers of 1000. Appending 'B' to the SI unit
|
52 |
+
prefix multiplies the value by 8. This allows using, for example: 'KB',
|
53 |
+
'MiB', 'G' and 'B' as number suffixes.
|
54 |
+
|
55 |
+
Options which do not take arguments are boolean options, and set the
|
56 |
+
corresponding value to true. They can be set to false by prefixing the
|
57 |
+
option name with "no". For example using "-nofoo" will set the boolean
|
58 |
+
option with name "foo" to false.
|
59 |
+
|
60 |
+
Stream specifiers
|
61 |
+
Some options are applied per-stream, e.g. bitrate or codec. Stream
|
62 |
+
specifiers are used to precisely specify which stream(s) a given option
|
63 |
+
belongs to.
|
64 |
+
|
65 |
+
A stream specifier is a string generally appended to the option name
|
66 |
+
and separated from it by a colon. E.g. "-codec:a:1 ac3" contains the
|
67 |
+
"a:1" stream specifier, which matches the second audio stream.
|
68 |
+
Therefore, it would select the ac3 codec for the second audio stream.
|
69 |
+
|
70 |
+
A stream specifier can match several streams, so that the option is
|
71 |
+
applied to all of them. E.g. the stream specifier in "-b:a 128k"
|
72 |
+
matches all audio streams.
|
73 |
+
|
74 |
+
An empty stream specifier matches all streams. For example, "-codec
|
75 |
+
copy" or "-codec: copy" would copy all the streams without reencoding.
|
76 |
+
|
77 |
+
Possible forms of stream specifiers are:
|
78 |
+
|
79 |
+
stream_index
|
80 |
+
Matches the stream with this index. E.g. "-threads:1 4" would set
|
81 |
+
the thread count for the second stream to 4. If stream_index is
|
82 |
+
used as an additional stream specifier (see below), then it selects
|
83 |
+
stream number stream_index from the matching streams. Stream
|
84 |
+
numbering is based on the order of the streams as detected by
|
85 |
+
libavformat except when a program ID is also specified. In this
|
86 |
+
case it is based on the ordering of the streams in the program.
|
87 |
+
|
88 |
+
stream_type[:additional_stream_specifier]
|
89 |
+
stream_type is one of following: 'v' or 'V' for video, 'a' for
|
90 |
+
audio, 's' for subtitle, 'd' for data, and 't' for attachments. 'v'
|
91 |
+
matches all video streams, 'V' only matches video streams which are
|
92 |
+
not attached pictures, video thumbnails or cover arts. If
|
93 |
+
additional_stream_specifier is used, then it matches streams which
|
94 |
+
both have this type and match the additional_stream_specifier.
|
95 |
+
Otherwise, it matches all streams of the specified type.
|
96 |
+
|
97 |
+
p:program_id[:additional_stream_specifier]
|
98 |
+
Matches streams which are in the program with the id program_id. If
|
99 |
+
additional_stream_specifier is used, then it matches streams which
|
100 |
+
both are part of the program and match the
|
101 |
+
additional_stream_specifier.
|
102 |
+
|
103 |
+
#stream_id or i:stream_id
|
104 |
+
Match the stream by stream id (e.g. PID in MPEG-TS container).
|
105 |
+
|
106 |
+
m:key[:value]
|
107 |
+
Matches streams with the metadata tag key having the specified
|
108 |
+
value. If value is not given, matches streams that contain the
|
109 |
+
given tag with any value.
|
110 |
+
|
111 |
+
u Matches streams with usable configuration, the codec must be
|
112 |
+
defined and the essential information such as video dimension or
|
113 |
+
audio sample rate must be present.
|
114 |
+
|
115 |
+
Note that in ffmpeg, matching by metadata will only work properly
|
116 |
+
for input files.
|
117 |
+
|
118 |
+

-loglevel [flags+]loglevel | -v [flags+]loglevel
|
242 |
+
Set logging level and flags used by the library.
|
243 |
+
|
244 |
+
The optional flags prefix can consist of the following values:
|
245 |
+
|
246 |
+
repeat
|
247 |
+
Indicates that repeated log output should not be compressed to
|
248 |
+
the first line and the "Last message repeated n times" line
|
249 |
+
will be omitted.
|
250 |
+
|
251 |
+
level
|
252 |
+
Indicates that log output should add a "[level]" prefix to each
|
253 |
+
message line. This can be used as an alternative to log
|
254 |
+
coloring, e.g. when dumping the log to file.
|
255 |
+
|
256 |
+
Flags can also be used alone by adding a '+'/'-' prefix to
|
257 |
+
set/reset a single flag without affecting other flags or changing
|
258 |
+
loglevel. When setting both flags and loglevel, a '+' separator is
|
259 |
+
expected between the last flags value and before loglevel.
|
260 |
+
|
261 |
+
loglevel is a string or a number containing one of the following
|
262 |
+
values:
|
263 |
+
|
264 |
+
quiet, -8
|
265 |
+
Show nothing at all; be silent.
|
266 |
+
|
267 |
+
panic, 0
|
268 |
+
Only show fatal errors which could lead the process to crash,
|
269 |
+
such as an assertion failure. This is not currently used for
|
270 |
+
anything.
|
271 |
+
|
272 |
+
fatal, 8
|
273 |
+
Only show fatal errors. These are errors after which the
|
274 |
+
process absolutely cannot continue.
|
275 |
+
|
276 |
+
error, 16
|
277 |
+
Show all errors, including ones which can be recovered from.
|
278 |
+
|
279 |
+
warning, 24
|
280 |
+
Show all warnings and errors. Any message related to possibly
|
281 |
+
incorrect or unexpected events will be shown.
|
282 |
+
|
283 |
+
info, 32
|
284 |
+
Show informative messages during processing. This is in
|
285 |
+
addition to warnings and errors. This is the default value.
|
286 |
+
|
287 |
+
verbose, 40
|
288 |
+
Same as "info", except more verbose.
|
289 |
+
|
290 |
+
debug, 48
|
291 |
+
Show everything, including debugging information.
|
292 |
+
|
293 |
+
trace, 56
|
294 |
+
|
295 |
+
For example to enable repeated log output, add the "level" prefix,
|
296 |
+
and set loglevel to "verbose":
|
297 |
+
|
298 |
+
ffmpeg -loglevel repeat+level+verbose -i input output
|
299 |
+
|
300 |
+
Another example that enables repeated log output without affecting
|
301 |
+
current state of "level" prefix flag or loglevel:
|
302 |
+
|
303 |
+
ffmpeg [...] -loglevel +repeat
|
304 |
+
|
305 |
+
By default the program logs to stderr. If coloring is supported by
|
306 |
+
the terminal, colors are used to mark errors and warnings. Log
|
307 |
+
coloring can be disabled setting the environment variable
|
308 |
+
AV_LOG_FORCE_NOCOLOR, or can be forced setting the environment
|
309 |
+
variable AV_LOG_FORCE_COLOR.
|
310 |
+
|
311 |
+
-report
|
312 |
+
Dump full command line and log output to a file named
|
313 |
+
"program-YYYYMMDD-HHMMSS.log" in the current directory. This file
|
314 |
+
can be useful for bug reports. It also implies "-loglevel debug".
|
315 |
+
|
316 |
+
Setting the environment variable FFREPORT to any value has the same
|
317 |
+
effect. If the value is a ':'-separated key=value sequence, these
|
318 |
+
options will affect the report; option values must be escaped if
|
319 |
+
they contain special characters or the options delimiter ':' (see
|
320 |
+
the ``Quoting and escaping'' section in the ffmpeg-utils manual).
|
321 |
+
|
322 |
+
The following options are recognized:
|
323 |
+
|
324 |
+
file
|
325 |
+
set the file name to use for the report; %p is expanded to the
|
326 |
+
name of the program, %t is expanded to a timestamp, "%%" is
|
327 |
+
expanded to a plain "%"
|
328 |
+
|
329 |
+
level
|
330 |
+
set the log verbosity level using a numerical value (see
|
331 |
+
"-loglevel").
|
332 |
+
|
333 |
+
For example, to output a report to a file named ffreport.log using
|
334 |
+
a log level of 32 (alias for log level "info"):
|
335 |
+
|
336 |
+
FFREPORT=file=ffreport.log:level=32 ffmpeg -i input output
|
337 |
+
|
338 |
+
Errors in parsing the environment variable are not fatal, and will
|
339 |
+
not appear in the report.
|
340 |
+
|
341 |
+
-hide_banner
|
342 |
+
Suppress printing banner.
|
343 |
+
|
344 |
+
All FFmpeg tools will normally show a copyright notice, build
|
345 |
+
options and library versions. This option can be used to suppress
|
346 |
+
printing this information.
|
347 |
+
|
348 |
+
-cpuflags flags (global)
|
349 |
+
Allows setting and clearing cpu flags. This option is intended for
|
350 |
+
testing. Do not use it unless you know what you're doing.
|
351 |
+
|
352 |
+
ffmpeg -cpuflags -sse+mmx ...
|
353 |
+
ffmpeg -cpuflags mmx ...
|
354 |
+
ffmpeg -cpuflags 0 ...
|

+
-cpucount count (global)
|
404 |
+
Override detection of CPU count. This option is intended for
|
405 |
+
testing. Do not use it unless you know what you're doing.
|
406 |
+
|
407 |
+
ffmpeg -cpucount 2
|
408 |
+
|
409 |
+
-max_alloc bytes
|
410 |
+
Set the maximum size limit for allocating a block on the heap by
|
411 |
+
ffmpeg's family of malloc functions. Exercise extreme caution when
|
412 |
+
using this option. Don't use if you do not understand the full
|
413 |
+
consequence of doing so. Default is INT_MAX.
|
414 |
+
|
415 |
+
AVOptions
|
416 |
+
These options are provided directly by the libavformat, libavdevice and
|
417 |
+
libavcodec libraries. To see the list of available AVOptions, use the
|
418 |
+
-help option. They are separated into two categories:
|
419 |
+
|
420 |
+
generic
|
421 |
+
These options can be set for any container, codec or device.
|
422 |
+
Generic options are listed under AVFormatContext options for
|
423 |
+
containers/devices and under AVCodecContext options for codecs.
|
424 |
+
|
425 |
+
private
|
426 |
+
These options are specific to the given container, device or codec.
|
427 |
+
Private options are listed under their corresponding
|
428 |
+
containers/devices/codecs.
|
429 |
+
|
430 |
+
For example to write an ID3v2.3 header instead of a default ID3v2.4 to
|
431 |
+
an MP3 file, use the id3v2_version private option of the MP3 muxer:
|
432 |
+
|
433 |
+
ffmpeg -i input.flac -id3v2_version 3 out.mp3
|
434 |
+
|
435 |
+
All codec AVOptions are per-stream, and thus a stream specifier should
|
436 |
+
be attached to them:
|
437 |
+
|
438 |
+
ffmpeg -i multichannel.mxf -map 0:v:0 -map 0:a:0 -map 0:a:0 -c:a:0 ac3 -b:a:0 640k -ac:a:1 2 -c:a:1 aac -b:2 128k out.mp4
|
439 |
+
|
440 |
+
In the above example, a multichannel audio stream is mapped twice for
|
441 |
+
output. The first instance is encoded with codec ac3 and bitrate 640k.
|
442 |
+
The second instance is downmixed to 2 channels and encoded with codec
|
443 |
+
aac. A bitrate of 128k is specified for it using absolute index of the
|
444 |
+
output stream.
|
445 |
+
|
446 |
+
Note: the -nooption syntax cannot be used for boolean AVOptions, use
|
447 |
+
-option 0/-option 1.
|
448 |
+
|
449 |
+
Note: the old undocumented way of specifying per-stream AVOptions by
|
450 |
+
prepending v/a/s to the options name is now obsolete and will be
|
451 |
+
removed soon.
|
452 |
+
|
453 |
+
Main options

+
-of, -print_format writer_name[=writer_options]
|
475 |
+
Set the output printing format.
|
476 |
+
|
477 |
+
writer_name specifies the name of the writer, and writer_options
|
478 |
+
specifies the options to be passed to the writer.
|
479 |
+
|
480 |
+
For example for printing the output in JSON format, specify:
|
481 |
+
|
482 |
+
-print_format json
|
483 |
+
|
484 |
+
For more details on the available output printing formats, see the
|
485 |
+
Writers section below.
|
486 |
+
|
487 |
+
-sections
|
488 |
+
Print sections structure and section information, and exit. The
|
489 |
+
output is not meant to be parsed by a machine.
|
490 |
+
|
491 |
+
-select_streams stream_specifier
|
492 |
+
Select only the streams specified by stream_specifier. This option
|
493 |
+
affects only the options related to streams (e.g. "show_streams",
|
494 |
+
"show_packets", etc.).
|
495 |
+
|
496 |
+
For example to show only audio streams, you can use the command:
|
497 |
+
|
498 |
+
ffprobe -show_streams -select_streams a INPUT
|
499 |
+
|
500 |
+
To show only video packets belonging to the video stream with index
|
501 |
+
1:
|
502 |
+
|
503 |
+
ffprobe -show_packets -select_streams v:1 INPUT
|
504 |
+
|
505 |
+
-show_data
|
506 |
+
Show payload data, as a hexadecimal and ASCII dump. Coupled with
|
507 |
+
-show_packets, it will dump the packets' data. Coupled with
|
508 |
+
-show_streams, it will dump the codec extradata.
|
509 |
+
|
510 |
+
The dump is printed as the "data" field. It may contain newlines.
|
511 |
+
|
512 |
+
-show_data_hash algorithm
|
513 |
+
Show a hash of payload data, for packets with -show_packets and for
|
514 |
+
codec extradata with -show_streams.
|
515 |
+
|
516 |
+
-show_error
|
517 |
+
Show information about the error found when trying to probe the
|
518 |
+
input.
|
519 |
+
|
520 |
+
The error information is printed within a section with name
|
521 |
+
"ERROR".
|
522 |
+
|
523 |
+
-show_format
|
524 |
+
Show information about the container format of the input multimedia
|
525 |
+
stream.
|
526 |
+
|
527 |
+
All the container format information is printed within a section
|
528 |
+
with name "FORMAT".
|
529 |
+
|
530 |
+
-show_format_entry name
|
531 |
+
Like -show_format, but only prints the specified entry of the
|
532 |
+
container format information, rather than all. This option may be
|
533 |
+
given more than once, then all specified entries will be shown.
|
534 |
+
|
535 |
+
This option is deprecated, use "show_entries" instead.
|
536 |
+
|
537 |
+
-show_entries section_entries
|
538 |
+
Set list of entries to show.
|
539 |
+
|
540 |
+
Entries are specified according to the following syntax.
|
541 |
+
section_entries contains a list of section entries separated by
|
542 |
+
":". Each section entry is composed by a section name (or unique
|
543 |
+
name), optionally followed by a list of entries local to that
|
544 |
+
section, separated by ",".
|
545 |
+
|
546 |
+
If section name is specified but is followed by no "=", all entries
|
547 |
+
are printed to output, together with all the contained sections.
|
548 |
+
Otherwise only the entries specified in the local section entries
|
549 |
+
list are printed. In particular, if "=" is specified but the list
|
550 |
+
of local entries is empty, then no entries will be shown for that
|
551 |
+
section.
|
552 |
+
|
553 |
+
Note that the order of specification of the local section entries
|
554 |
+
is not honored in the output, and the usual display order will be
|
555 |
+
retained.
|
556 |
+
|
557 |
+
The formal syntax is given by:
|
558 |
+
|
559 |
+
<LOCAL_SECTION_ENTRIES> ::= <SECTION_ENTRY_NAME>[,<LOCAL_SECTION_ENTRIES>]
|
560 |
+
<SECTION_ENTRY> ::= <SECTION_NAME>[=[<LOCAL_SECTION_ENTRIES>]]
|
561 |
+
<SECTION_ENTRIES> ::= <SECTION_ENTRY>[:<SECTION_ENTRIES>]
|
562 |
+
|
563 |
+
For example, to show only the index and type of each stream, and
|
564 |
+
the PTS time, duration time, and stream index of the packets, you
|
565 |
+
can specify the argument:
|
566 |
+
|
567 |
+
packet=pts_time,duration_time,stream_index : stream=index,codec_type
|
568 |
+
|
569 |
+
To show all the entries in the section "format", but only the codec
|
570 |
+
type in the section "stream", specify the argument:
|
571 |
+
|
572 |
+
format : stream=codec_type
|
573 |
+
|
574 |
+
To show all the tags in the stream and format sections:
|
575 |
+
|
576 |
+
stream_tags : format_tags
|
577 |
+
|
578 |
+
To show only the "title" tag (if available) in the stream sections:
|
579 |
+
|
580 |
+
stream_tags=title
|
581 |
+
|
582 |
+
-show_packets
|
583 |
+
Show information about each packet contained in the input
|
584 |
+
multimedia stream.
|
585 |
+
|
586 |
+
The information for each single packet is printed within a
|
587 |
+
dedicated section with name "PACKET".
|
588 |
+
|
589 |
+
-show_frames
|
590 |
+
Show information about each frame and subtitle contained in the
|
591 |
+
input multimedia stream.
|
592 |
+
|
593 |
+
The information for each single frame is printed within a dedicated
|
594 |
+
section with name "FRAME" or "SUBTITLE".
|
595 |
+
|
596 |
+
-show_log loglevel
|
597 |
+
Show logging information from the decoder about each frame
|
598 |
+
according to the value set in loglevel, (see "-loglevel"). This
|
599 |
+
option requires "-show_frames".
|
600 |
+
|
601 |
+
The information for each log message is printed within a dedicated
|
602 |
+
section with name "LOG".
|
603 |
+
|
604 |
+
-show_streams
|
605 |
+
Show information about each media stream contained in the input
|
606 |
+
multimedia stream.
|
607 |
+
|
608 |
+
Each media stream information is printed within a dedicated section
|
609 |
+
with name "STREAM".
|
610 |
+
|
611 |
+
-show_programs
|
612 |
+
Show information about programs and their streams contained in the
|
613 |
+
input multimedia stream.
|
614 |
+
|
615 |
+
Each media stream information is printed within a dedicated section
|
616 |
+
with name "PROGRAM_STREAM".
|
617 |
+
|
618 |
+
-show_chapters
|
619 |
+
Show information about chapters stored in the format.
|
620 |
+
|
621 |
+
Each chapter is printed within a dedicated section with name
|
622 |
+
"CHAPTER".
|
623 |
+
|
624 |
+
-count_frames
|
625 |
+
Count the number of frames per stream and report it in the
|
626 |
+
corresponding stream section.
|
627 |
+
|
628 |
+
-count_packets
|
629 |
+
Count the number of packets per stream and report it in the
|
630 |
+
corresponding stream section.
|
631 |
+
|
632 |
+
-read_intervals read_intervals
|
633 |
+
Read only the specified intervals. read_intervals must be a
|
634 |
+
sequence of interval specifications separated by ",". ffprobe will
|
635 |
+
seek to the interval starting point, and will continue reading from
|
636 |
+
that.
|
637 |
+
|
638 |
+
Each interval is specified by two optional parts, separated by "%".
|
639 |
+
|
640 |
+
The first part specifies the interval start position. It is
|
641 |
+
interpreted as an absolute position, or as a relative offset from
|
642 |
+
the current position if it is preceded by the "+" character. If
|
643 |
+
this first part is not specified, no seeking will be performed when
|
644 |
+
reading this interval.
|
645 |
+
|
646 |
+
The second part specifies the interval end position. It is
|
647 |
+
interpreted as an absolute position, or as a relative offset from
|
648 |
+
the current position if it is preceded by the "+" character. If the
|
649 |
+
offset specification starts with "#", it is interpreted as the
|
650 |
+
number of packets to read (not including the flushing packets) from
|
651 |
+
the interval start. If no second part is specified, the program
|
652 |
+
will read until the end of the input.
|
653 |
+
|
654 |
+
Note that seeking is not accurate, thus the actual interval start
|
655 |
+
point may be different from the specified position. Also, when an
|
656 |
+
interval duration is specified, the absolute end time will be
|
657 |
+
computed by adding the duration to the interval start point found
|
658 |
+
by seeking the file, rather than to the specified start value.
|
659 |
+
|
660 |
+
The formal syntax is given by:
|
661 |
+
|
662 |
+
<INTERVAL> ::= [<START>|+<START_OFFSET>][%[<END>|+<END_OFFSET>]]
|
663 |
+
<INTERVALS> ::= <INTERVAL>[,<INTERVALS>]
|
664 |
+
|
665 |
+
A few examples follow.
|
666 |
+
|
667 |
+
o Seek to time 10, read packets until 20 seconds after the found
|
668 |
+
seek point, then seek to position "01:30" (1 minute and thirty
|
669 |
+
seconds) and read packets until position "01:45".
|
670 |
+
|
671 |
+
10%+20,01:30%01:45
|
672 |
+
|
673 |
+
o Read only 42 packets after seeking to position "01:23":
|
674 |
+
|
675 |
+
01:23%+#42
|
676 |
+
|
677 |
+
o Read only the first 20 seconds from the start:
|
678 |
+
|
679 |
+
%+20
|
680 |
+
|
681 |
+
o Read from the start until position "02:30":
|
682 |
+
|
683 |
+
%02:30
|
684 |
+
|
685 |
+
-show_private_data, -private
|
686 |
+
Show private data, that is data depending on the format of the
|
687 |
+
particular shown element. This option is enabled by default, but
|
688 |
+
you may need to disable it for specific uses, for example when
|
689 |
+
creating XSD-compliant XML output.
|
690 |
+
|
691 |
+
-show_program_version
|
692 |
+
Show information related to program version.
|
693 |
+
|
694 |
+
Version information is printed within a section with name
|
695 |
+
"PROGRAM_VERSION".
|
696 |
+
|
697 |
+
-show_library_versions
|
698 |
+
Show information related to library versions.
|
699 |
+
|
700 |
+
Version information for each library is printed within a section
|
701 |
+
with name "LIBRARY_VERSION".
|
702 |
+
|
703 |
+
-show_versions
|
704 |
+
Show information related to program and library versions. This is
|
705 |
+
the equivalent of setting both -show_program_version and
|
706 |
+
-show_library_versions options.
|
707 |
+
|
708 |
+
-show_pixel_formats
|
709 |
+
Show information about all pixel formats supported by FFmpeg.
|
710 |
+
|
711 |
+
Pixel format information for each format is printed within a
|
712 |
+
section with name "PIXEL_FORMAT".
|
713 |
+
|
714 |
+
-show_optional_fields value
|
715 |
+
Some writers viz. JSON and XML, omit the printing of fields with
|
716 |
+
invalid or non-applicable values, while other writers always print
|
717 |
+
them. This option enables one to control this behaviour. Valid
|
718 |
+
values are "always"/1, "never"/0 and "auto"/"-1". Default is auto.
|
719 |
+
|
720 |
+
-bitexact
|
721 |
+
Force bitexact output, useful to produce output which is not
|
722 |
+
dependent on the specific build.
|
723 |
+
|
724 |
+
-i input_url
|
725 |
+
Read input_url.
|
726 |
+
|
727 |
+
-o output_url
|
728 |
+
Write output to output_url. If not specified, the output is sent to
|
729 |
+
stdout.
|
730 |
+
|
731 |
+
WRITERS
|
732 |
+
A writer defines the output format adopted by ffprobe, and will be used
|
733 |
+
for printing all the parts of the output.
|
734 |
+
|
735 |
+
A writer may accept one or more arguments, which specify the options to
|
736 |
+
adopt. The options are specified as a list of key=value pairs,
|
737 |
+
separated by ":".
|
738 |
+
|
739 |
+
All writers support the following options:
|
740 |
+
|
741 |
+
string_validation, sv
|
742 |
+
Set string validation mode.
|
743 |
+
|
744 |
+
The following values are accepted.
|
745 |
+
|
746 |
+
fail
|
747 |
+
The writer will fail immediately in case an invalid string
|
748 |
+
(UTF-8) sequence or code point is found in the input. This is
|
749 |
+
especially useful to validate input metadata.
|
750 |
+
|
751 |
+
ignore
|
752 |
+
Any validation error will be ignored. This will result in
|
753 |
+
possibly broken output, especially with the json or xml writer.
|
754 |
+
|
755 |
+
replace
|
756 |
+
The writer will substitute invalid UTF-8 sequences or code
|
757 |
+
points with the string specified with the
|
758 |
+
string_validation_replacement.
|
759 |
+
|
760 |
+
Default value is replace.
|
761 |
+
|
762 |
+
string_validation_replacement, svr
|
763 |
+
Set replacement string to use in case string_validation is set to
|
764 |
+
replace.
|
765 |
+
|
766 |
+
In case the option is not specified, the writer will assume the
|
767 |
+
empty string, that is it will remove the invalid sequences from the
|
768 |
+
input strings.
|
769 |
+
|
770 |
+
A description of the currently available writers follows.
|
771 |
+
|
772 |
+
default
|
773 |
+
Default format.
|
774 |

|
780 |
+
keyN=valN
|
781 |
+
[/SECTION]
|
782 |
+
|
783 |
+
Metadata tags are printed as a line in the corresponding FORMAT, STREAM
|

|
827 |
+
|
828 |
+
c Perform C-like escaping. Strings containing a newline (\n),
|
829 |
+
carriage return (\r), a tab (\t), a form feed (\f), the
|
830 |
+
escaping character (\) or the item separator character SEP are
|
831 |
+
escaped using C-like fashioned escaping, so that a newline is
|
832 |
+
converted to the sequence \n, a carriage return to \r, \ to \\
|
833 |
+
and the separator SEP is converted to \SEP.
|
834 |
+
|
835 |

849 |
+
A free-form output where each line contains an explicit key=value, such
|
850 |
+
as "streams.stream.3.tags.foo=bar". The output is shell escaped, so it
|
851 |
+
can be directly embedded in sh scripts as long as the separator
|
852 |
+
character is an alphanumeric character or an underscore (see sep_char
|
853 |
+
option).
