System info:
- Ubuntu 15.04 32-bit
- GPAC version 0.6.2-DEV-rev455-gb16f730-master
Im trying to generate dash live dynamic content. First of all MP4Box with dash works fine for this MP4Box -dash 2000 -out stream.mpd ~/Downloads/awakens.mp4
and
MP4Box -dash 2000 -profile live -out stream.mpd ~/Downloads/awakens.mp4#video ~/Downloads/awakens.mp4#audio
It doesn't work for switch -dynamic and for -dash-live.
MP4Box -dash-live 2000 -mpd-refresh 2.0 -out stream.mpd ~/Downloads/awakens.mp4#video ~/Downloads/awakens.mp4#audio
When im trying to play mpd file with MP4Client there are lags of video and after lag it goes faster(there is no leak of frames and audio goes normal) - and then, because of video's lags video and audio are not synchronized at all. After end of audio (not video) there is info:
```

When playing DASH contents , I noticed in the statistics window that the player has a bufferlength about maybe 6 second, which I think is some kinds of short, and I want to try some longger buffer length.(I did't mean the buffer to be filled before starting decoding which can be set in the GPAC configuration documentation ). How can I make this happen?
Thanks a lot！

Hello,
I am running on FEDORA 23, 64bit and this GPAC version:
MP4Box - GPAC version 0.6.2-DEV-rev455-gb16f730-master
Currently, I am trying to generate a DASH segments and manifest with byte ranges and segment timeline for duration of each segment. I will parse that .mpd file to create a .csv file with information needed for my system.
I am using this command:
`/usr/local/bin/MP4Box
-dash 1
-frag-rap
-no-frags-default
-segment-timeline
-tmp [...]/temp/ac4245ba-bdb8-48ca-a926-10a5495cdfc4
-out [...]/temp/ac4245ba-bdb8-48ca-a926-10a5495cdfc4/[filename]-video-timescaled_dash.mpd
[...]/temp/ac4245ba-bdb8-48ca-a926-10a5495cdfc4/[filename]-video-timescaled.mp4`
This generates this part of manifest file:
``` xml
<?xml version="1.0"?>

```
File looks like any other but there is a mistake: `<SegmentList timescale="1000"`. There is a missing character '>' at the end. That is why I get this error when parsing in Java:
<p>[Fatal Error] [filename]-video-timescaled_dash.mpd:11:5: Element type "SegmentList" must be followed by either attribute specifications, ">" or "/>".<br/>

at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:205)</p>
I have wrote all information I have. I am not very skilled with reporting issues, so if I did something wrong I apologize.
I am looking for a way to fix this mistake as fast as possible, so if I can patch it quickly that would be an option, before a release fix comes. I might need help with patching this because I do not even know where to look for this bug in the code.
Thank you very much for help.

I have consulted on dash.js forum the question. Please see here: https://github.com/Dash-Industry-Forum/dash.js/issues/1385
I use ffmpeg receive streaming, output MP4 file(every 4 secs), then separate file, one is video encoded 264 (There will be multiple files for ABS, but now only test one video file), other is audio encoded aac (Lavf57.25.100). The first I only test video and only audio, they are working properly. However, when mix video and audio error occurred.
chrome ver: 49.0.2623.87 m
dash.js ver: 2.2
GPAC ver: 0.5, and latest
System: centoOS Linux 32bits
My DASH commend line is:
MP4Box -min-buffer 2000 -time-shift 10 -dash 2000 -frag 2000 -dash-live 2000 -mpd-refresh 4 -profile "dashavc264:live" -bs-switching no -rap -segment-name video/segment_ -out mpdtest.mpd MacrossDelta/MacrossDelta_audio_02.mp4#audio ff+box/MacrossDelta_1500k_02_N.mp4#video

Can't get next segment.
If there is no clear description of anywhere, please let me know. I do not have enough knowledge confirmed this issue. Someone can give me some advice to try? or this is a known Issues?
Any help I will be very grateful, thank you.

I would like to do some changes and adapt a new rate adaption algorithm in DASH player (OSMO4) in the GPAC framework, but I felt confused about how to do it. Is it enough to just read and modify the code in gpac/src/media_tools/dash_client.c ? I would appreciate it a lot if anyone could give some instructions.

I am using the -isma option but there doesn't seem to be a way to find out if it's needed.
When I run MP4Box -isma the second time, it just starts to rewrite again.
Is there a way to find out (with -info ?) if -isma is needed or not?

Hope you are all fine and enjoying your time.
I am running the DashCast with HEVC codec, however while making live streaming I experience a delay of about 5 seconds!.
Is there any way to reduce this delay, although I am using a quite powerful machine as you can see in bellow:

Hello,
I was trying to build gpac for Android according to instructions (but in Android Studio) on https://github.com/gpac/gpac/blob/master/build/android/README.
While compiling the extra-libs (point 3), it failed because the gcc path does not exist. However, there is a path through "arm-linux-androideabi-4.9", seems like only a version mismatch.

The prog1 produce the h265 stream and save it to file.
I want to put the h265 stream to mp4box and produce a mp4 file then save it.
But I found mp4box reads a file that had saved in storage device, if I can use mp4box reads the stream not from a file but from memory.
I found "gmem://%d@%p" in source code. Whether "gmem://%d@%p" means mp4box can get data from a memory address.
If "gmem://%d@%p" means mp4box can get data from a memory address, then gf_fopen(fileName, "rb"), now assumption fileName=gmem://100@AABB, gf_fopen while load fopen(file_name, mode), and whether fopen will return NULL.
If the above , I takes a wrong way, how can I use mp4box not read data from a file but from another program produced data.

"gmem://%d@%p" is a way get data from memory or not

I have a situation similar to this:
```
MP4Box -dash 4000 input1.mp4#role=main:desc_as='<SupplementalProperty schemeIdUri="my:test:uri" value="1"/>' input2.mp4#role=main:desc_as='<SupplementalProperty schemeIdUri="my:test:uri" value="1"/>'
```
Two identical desc_as definitions.
That kind of command line ends up in a MPD where input1.mp4 and input2.mp4 are in DIFFERENT AdaptationSets even though they have the same role and identical desc_as. If I remove my desc_as definitions:
MP4Box -dash 4000 input1.mp4#role=main input2.mp4#role=main
..now input1.mp4 and input2.mp4 are in the SAME AdaptationSet in different Representations (as expected).
MP4Box documentation about as_desc says:
:desc_as=VALUE adds a descriptor at the AdaptationSet level. Value must be a properly formatted XML element. Two input files with _different_values_ will be in different AdaptationSet elements.
So something is not right here.
This was tested on Ubuntu 15.10 with GPac build from GitHub:

Hello all,
I've been searching online for a while about this issue, and have found one thread from a few years ago, that seems to mention the exact problem, but not describe a solution for it. That thread is here:
https://sourceforge.net/p/gpac/discussion/287547/thread/6fa58849/
The issue that I am seeing, which is interestingly my only remaining issue with DashCast at this point ( aside from some a/v sync issues, if anyone needs assistance or an FAQ on DashCast I may be able to offer some help or guidance. ) is that with multiple video representations (various bitrates and outputs for the dash segments), DashCast will begin encoding ONLY video segments very quickly (audio continues perfectly). However, upon further inspection of these video segments, one will note that they are not actually video segments, and though named correctly, contain no parseable MPEG-DASH data.
**Assuming 8 second segments, the scenario where the issue prevents itself will look like this.**
1) Segments are encoded about every ~7-8 seconds until some arbitrary segment number ( e.g `v1_seg_655.m4s, v2_seg_655.m4s, a1_seg_655.m4s`)
2) Suddenly, every second or so, a new video segment will come out numbered after the previous and audio will continue encoding every ~7-8 seconds as expected. The new video segments will be corrupted and unusable.
3) Another note is that CPU usage of DashCast will spike at this point, using 15-20x what the normal command would use.
4) One can kill and restart the DashCast command and have it start from the beginning which will solve the issue until it occurs again in the next iteration.

**MY THOUGHTS**
I have a few thoughts on the issue that may help in coming to some sort of solution but are just thoughts I've had throughout this debacle.
--I know that it is directly related to number of outputs. The more outputs there are, the faster DashCast will encounter this problem.
--I know that when running other encoding(such as HLS or RTSP) on the same machine, DashCast will also encounter the problem faster.
-Because of the above two points, the issue most certainly has something to do with CPU usage.
-I also know that the issue prevents itself whether I use `-live-media` or just `-live`. Live seems to be the right choice for UDP input, but the response from `-live-media` is much more succinct and shows actual legible output when the issue happens which is : `[dashcast] Live system dropped a video frame`
-Finally I fear that perhaps the container format `mpegts` from my `ffmpeg` command could be part of the problem as well.
I reiterate that these are just my thoughts and don't necessarily have anything to do with the issue.
Thank you so much for taking a look at this and please let me know if there is anything else you need from me,
Carter

Hi guys.
I have a fresh installation of the GPAC version 0.6.2-DEV-rev262-g3f28607-master on Ubuntu Server 15.10.
I have followed the guide https://gpac.wp.mines-telecom.fr/dashcast/ on installing, building and configuring FFMPEG, H264 and GPAC. All setup went through without issues. and i am at the stage of testing DashCast with live multicast sources.
My aim is to reproduce the test described here: http://www.gpac-licensing.com/2014/07/09/lowering-dash-live-latency-240ms/ though its a bit dated, i was hoping things have improved :-)
anyways, i am having an issue when using Dashcast with live UDP source.
thats my basic command which fails with the error of
> [dashcast] Live system dropped a video frame
here is my command and output:
> y@GPAC:~/dash$ sudo DashCast -av "udp://236.44.100.1:5200?fifo_size=100000&buffer_size=500000" -live -out output -mpd livetest.mpd

I have tried this with various udp sources to make sure its not the source, and the result is always the same, as soon as i tell DashCast its a -Live content i am getting the error.
Now, interestingly enough, if i dont tell it its live and do a straight command
> DashCast -av "udp://236.44.100.1:5200?fifo_size=100000&buffer_size=500000" -out output -mpd livetest.mpd
Its happily chunking away, without complaining. I didnt try the playback, but the files do start getting created in the output folder.
I didnt try this with the actual camera or screen capture source as this would be of no use to me, but i can certainly confirm that FFMPEG is happily demuxing the sources i am trying to use with DashCast
here is my FFMPEG build

would anyone be able to advise what could be causing this ?

Doc says:
`times is a formated as start-end, with start being sec, h:m:s:f/fps or h:m:s:ms`
Spec parses:
`sscanf(arg, "%02ud:%02ud:%02ud:%02ud", &h, &m, &s, &ms)`
So my first guess `-avi 0:0:10:0` failed silently (so we should add logs on failure).

I'm finding a way to import (-add) a video track in a new file assigning it always the trackid #1 independently by the original trackid.
Is it possible by using -set-track-id (by example by specifying 0:1 or *:1)?

Hi all!
I have two files that I grabbed off YT using the youtube-dl and I'm trying to join them. I've tried the following:
```
mp4box -cat file1.mp4 -cat file2.mp4 out.mp4
```
but that produced a file that played properly for the duration of file1.mp4 only and the screen was black for the second part.
I believe the issue is that Track #1 of file1.mp4 is video and track #2 is audio. However. for the file2.mp4, track #1 is audio and track #2 is video. I believe that mp4box is therefore not joining them properly.
Is it possible to merge them properly by somehow telling the mp4box which streams should go together?
Here's the info about files:

The issue seems to be caused by a download of another segment being started while the previous segment hasn't been fully received yet, and MP4Client being unable to deal with the resulting reply. See attached wireshark capture of a failed HTTP dialog where this is clearly visible.
This seem to be the case at least for versions 6.2 and 5.X.

I have trancoded a lot of files and all goes well, but some files fails on playback after dashing them, like this one:
http://movietrailers.apple.com/movies/independent/identicals/identicals-tlr_h1080p.mov
I can trancode then just fine using ffmpeg. The resulting files can be played just fine all the way through on all bitrates that I generate. BUT after dashing the file and trying to play the segmented files, it stops at 1:30, every thime.
I've tried to do it again and again, same result
An example of parameters that I use for ffmpeg: -y -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts 'keyint=48:min-keyint=48:no-scenecut:fps=24' -b:v 2048k
-b:a 128k -bufsize 1000k -vf "scale=-2:720"
and the dash arguments are like:
-dash 2000 -frag 2000 -rap (plus base-url, mpd title and some other "soft" parameters)
I don't know what happens at 1:30, but something sure throws off dash here.
Any help would be much appreciated

It's constant framerate movie, I wanted to cut out range between samples 77364 -> 185337.
In time domain it is 2581 -> 6184 s.
Execution:

Extracting chunk vid_1345_6184.mp4 - duration 4838.53s (1345.51s->6186.00s)
I don't get how it's been adjusted to RAP at 1345s, it's 20 minutes earlier point (sample 40305).
There must be something borked,

can anyone please help me to achieve live streaming using DashCast.
I am trying this command :
DashCast -vf video4linux2 -v4l2f mjpeg -v /dev/video0 -af alsa -out output/ -npts
which is creating segments, then on new terminal I am using
MP4Client output/dashcast.mpd
which is running successfully for sometime but then shows error of not finding new segments.
This error is because the MP4Client is searching segments at faster rates than DastCast creating it. Moreover this dashcast.mpd is not running with Dash.js
I have also tried -live and -live-media commands but with that the situation is getting worse as it is giving either error of "Live system dropped a video frame" or making improper frames which in result not showing any result.
I am new to this field, please suggest something to work it out.
Thanks in advance,
Himanshu

Hello,
Currently for iTunes, the -itags list seems really limited:
_MP4Box -tag-list
Supported iTunes tag modifiers:
album_artist usage: album_artist=album artist
album usage: album=name
tracknum usage: track=x/N
track usage: track=name
artist usage: artist=name
comment usage: comment=any comment
compilation usage: compilation=yes,no
composer usage: composer=name
created usage: created=time
disk usage: disk=x/N
tool usage: tool=name
genre usage: genre=name
name usage: name=name
tempo usage: tempo=integer
writer usage: writer=name
group usage: group=name
cover usage: cover=file.jpg,file.png
encoder usage: encoder=name
gapless usage: gapless=yes,no
all usage: all=NULL_
Am I missing something or was this done on purpose (because there is another way)?
There are quite some significant ones missing.
For example, how do I set things like:
- Video Type (Movie, TV Show, Home Video etc.)
- Season
- Episode
- Episode Title
- Episode ID
- HD Video
- Short Description/synopsis
- Long Description/plot
- iTunEXTC for rating
- iTunMOVI for the rest (Cast, Director, Producer etc.)
There more missing like xid, Artist ID, Lyrics, Playlist ID etc.
I had hoped I could do something with setting things like: MP4Box -set-meta "desc=Some Description" output.m4v
... but I guess that's for something else because it doesn't seem to do anything. Also, that way I wouldn't know how to add iTunEXTC and iTunMOVI.
Is there a workaround to somehow get these -itags in? Maybe using -udta somehow?
If not, would it be a good addition to add more options to the supported list?

When I execute MP4Box with parameters for placing the segment files in a folder, the segment files are located just as wanted.
My problem is, that I would also like to have the init file in the same folder, but no arguments I make enables this possibility :-(
**So I get this name of the init file**
initialization="34_init.mp4"
**And the segments**
media="34/segment_$Number$.m4s"
What I would like is:
initialization="34/34_init.mp4"
media="34/segment_$Number$.m4s"
How do I do that? I have tried with **-mpd-info-url=34/34_init.mp4**, but no luck
**Another thing is**
I have 3 input files
- zzz_lowband.mp4
- zzz_midband.mp4
- zzz_highband.mp4
I would like to have the segments in:
34/lowband/segments...
34/midband/segments...
34/highband/segments...
It this possible?
Thanks in advance

Hello,
I have generated an mp4-Video (HEVC - x265) with mp4box.exe (v0.6.2 rev.49). Fast forward or rewind - the VLC Player is very slow / hangs.
I had reported this error ever in sourceforce "https://sourceforge.net/p/gpac/bugs/353/".
Then I set the error on VLC "https://trac.videolan.org/vlc/ticket/16732#no4".
Result from VLC: Video track does provide stss which only tells first frame as sync point.
--> Broken file.
Please fix it...

Sorry for stupid question.
I have avi file with several ac3 audio tracks.
I try to create mp4 file from avi
`mp4box.exe -add "e:\test.avi#video:fps=23.976:packed" "e:\test.mp4"`
And get error "Unsupported AVI audio format" I think it's result that mp4box doesn't support AC3
But I didn't ask to put audio track to output file.
Does exist any option to disable audio output to result file?

There is a post here: https://sourceforge.net/p/gpac/bugs/349/ that is about this, but no open Github issues. It took me a while to get to the bottom of it, so I wanted to open an issue on Github. Not sure if this is the right protocol, but I thought it may help someone.
My fix is to take my input stream ( which happens to be coming from rtmp ) and use ffmpeg to re-encode the audio with aac to stereo with 44100 Hz and send it to a udp output that DashCast can read from.
The command looks like the following:
`ffmpeg -i [input] -c:a aac -ar 44100 -ac 2 -c:v copy udp://127.0.0.1:1234?pkt_size=13`
|
Audio Segments will have weird rumbling noise if the input sampling rate is not 44100 Hz

# Goal
I want to learn how to combinate segment-name init and index file names so I can specify them as I want.
## Starting point
I started out with this query:
`mp4box -dash 4000 -segment-name $RepresentationID$/segment_$Number$.m4s -out play.mpd -profile dashavc264:live -segment-ext null -mpd-title "" -mpd-info-url "" /full/path/dashify_file.mp4:id="video_hd"`
### Result
This generates segments just fine; but the init file will be named segment_.m4s
### Problem
Init file name is not desired name
### Desired result
I figured I wanted to rename init file to init.mp4 and the other segment files segment_$Number$.m4s
## Own research
I went to the [MP4Box Dash documentation](https://gpac.wp.mines-telecom.fr/mp4box/dash/)
and saw
- $Init=VALUE$ is replaced by VALUE if the generated file is an initialization segment,
- $Index=VALUE$ is replaced by VALUE if the generated file is an index segment.
Maybe I could do something with $Init=play.mp4$ ?
### So I tried
`mp4box -dash 4000 -profile live -segment-name $RepresentationID$/$Init=play.mp4$ -out play.mpd segment-ext null -lf log.txt /full/path/dashify_file.mp4:id=video_hd`
### Result
It works... kind of.
That gives me a video_hd folder with files 1-25 + the play.mp4!
But then the segments is just named 1-118
## What I need help with
I've tried different combinations of $Index=segment_%s$ and $Init together right after eachother, but I couldn't get anything to work. I also tried to make two segment-names.
There is no info on combining these even if I type mp4box -h dash so I am turning to you guys here instead!
## End word
Hope I provided you with enough information to understand and help me tackle this problem.
If there is something missing or I didn't make myself understood; please let me know and I will happily fill out the blanks :)

When I use latest mp4box (0.6.2-DEV-rev56-g30c5f14-master) to package CENC encrypted mp4 files, the generated presentation manifest contains the following:
```
<AdaptationSet segmentAlignment="true" maxWidth="1920" maxHeight="1080" maxFrameRate="30" par="16:9" lang="und">
<SegmentTemplate timescale="30" media="$RepresentationID$/$Number%04d$.m4s" startNumber="1" duration="120" initialization="$RepresentationID$/init.mp4" />
<ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" cenc:default_KID="7a4a1d66-0a65-4172-9267-38840795e42d" />
```
However, according to DASH specification the correct order is the opposite - `ContentProtection` must be before `SegmentTemplate`. This causes [validation of the manifest](http://dashif.org/conformance) to fail.
Here is the mp4box command line used:
```
mp4box.exe -noprog -dash-strict 4000 -out "ooo2\Encrypted\Manifest.mpd" -profile "dashavc264:live" -sample-groups-traf -bs-switching no "temp2\EncryptStreams\v-288-400k.mp4" "temp2\EncryptStreams\v-360-800k.mp4" "temp2\EncryptStreams\v-480-1200k.mp4" "temp2\EncryptStreams\v-720-2100k.mp4" "temp2\EncryptStreams\v-1080-3000k.mp4" "temp2\EncryptStreams\a.mp4" "temp2\EncodeTextStreams\TOS-zh.mp4" -segment-name $RepresentationID$\$Number%04d$$Init=init$
```
|
mp4box generates incorrect element order in DASH manifest for encrypted adaptation set

Hi,
It seems that to get the DASH-MPEG standard to work well with 8000 millisecond segments and SegmentTemplate, the availabilityStartTime needs to be about 20 seconds behind, so i have set in my DashCast command `-ast-offset 20000`. This generally works and ensures that the Dash Player will not look for segments that are so close to realtime that they have yet to be uploaded and registered by my CDN (S3 -> Cloudfront).
However, though sometimes it plays perfectly and the mpd is correct, other times it will set the availabilityStartTime in the mpd to be this: `availabilityStartTime="1900-01-01T00:00:20.000Z"`. Because of this, the player (dash.js) will look for enormous segment numbers and will not find them, causing the live video to be unplayable.
Is there something that I am doing wrong in my command? I'm not using a conf file, and my full command looks like this, omitting the input (-av) option, :`-live -seg-dur 8000 -ast-offset 20000 -min-buffer 16.0 -npts -low-delay -out /output`.
It appears to work consistently without the -ast-offset option and it sets the ast correctly. However, that will frequently cause the player to look for segments that don't exist yet.
It consistently sets the ast incorrectly when using a conf file as follows:
[v1]
type=video
width=1920
height=1080
bitrate=4000000
[a1]
type=audio
bitrate=128000
Thanks so much,
Carter

Hi, latest gpac nb is broken:
http://download.tsi.telecom-paristech.fr/gpac/latest_builds/win32/gpac-0.6.2-DEV-rev48-g30b4af0-master-win32.exe
File is only ~10MB.
I used to grab latest exes from there, but for example if I wanted "stable" 0.6.1 do I have to compile it myself or looking for exe on third party sites?

I have an SHVC encoded bitstream with an AVC encoded base layer. when I try to import this, I get an unhandled exception. I think the solution to this should be in the media_import.c file in the media tools folder of libgpac. Has this been done before ? Any leads will be really useful.

I have an SHVC coded bitstream produced from SHM 7.0. When I use MP4box to import this stream, Only the base layer spatial resolution is imported. The enhancement layer spatial resolution is not imported. There is no error thrown during the command. However when the converted mp4 content is DASHed, The MPD has only the the base layer resolution as the maximum available resolution , though there are two representations. To make things clearer, I will outline the steps to reproduce the problem
1. Encode a standard test sequence using SHM7.0
2. Import it into MP4box using the following command
MP4Box -new -add path\PeopleOnStreet-2x7.bin:FMT=SHVC:fps=30:svcmode=splitnox path\POS73.mp4
result:
HEVC import - frame size 960 x 540 at 30.000 FPS
SHVC detected - 0 x 0 at 30.000 FPS
HEVC Import results: 150 samples (606 NALUs) - Slices: 10 I 0 P 290 B - 300 SEI - 1 IDR
Stream uses forward prediction - stream CTS offset: 3 frames
OpenGOP detected - adjusting file brand
Saving path\POS73.mp4: 0.500 secs Interleaving
1. DASH the generated MP4 using
MP4Box -dash 4 -segment-name path\pos7 path\POS73.mp4
I dont encounter this problem when I have encoded a sequence using SHM4.1. This is the result of importing a SHM4.1 encoded stream into mp4box
HEVC import - frame size 1280 x 800 at 30.000 FPS
SHVC detected - 2560 x 1600 at 30.000 FPS
HEVC Import results: 8 samples (37 NALUs) - Slices: 2 I 0 P 14 B - 16 SEI - 1 IDR
Stream uses forward prediction - stream CTS offset: 2 frames
Saving C:\Amit\K2_SPDY\mp4BoxTest\POS41.mp4: 0.500 secs Interleaving
Thanks in Advance,

Recent compilers such as GCC5 and clang are defaulting C compilation to C99.
However GPAC wants to stay "C89 compliant", thus we should force the -ansi flag to always compile using C89.

Since iTunes is kinda picky, I'm trying to move audio tracks into the same group.
The -group-add options is giving me issues though.
When I try to move audio track 3 to the same group as track 2, I assume I need to do something like: ../MP4Box -group-add -refTrack=2:trackID=3 video.m4v
However, this gives: 'Error: Bad Parameter'.
MP4Box -group-single video.m4v
...exits without doing anything
MP4Box -group-clean video.m4v
...gives a 'Segmentation fault: 11'

Hello,
I am trying to use dashcast to transform a live multicast stream into a MPEG-DASH stream without any transcoding. I though it would be easy with the copy option from FFMPEG. But apparently it is not mapped to dashcast therefore I get this error:
```
Output video codec copy not found
Cannot open output video stream.
```
Here is my command line
```
dashcast.exe -av "udp://@238.4.4.4:5000?fifo_size=10000" -seg-dur 2000 -out "d:\temp" -conf dashcast.conf
```
and conf file
```
[v1]
type=video
codec=copy
[a1]
type=audio
codec=copy
```
Can you help me with this issue?
Thank you,
Luis

As of now, the HLS encryption support is limited to exporting the key url and AES initialization vector too the mpegts demuxer.
Looking at the ismacrypt module I do not see how that architecture could be used for HLS. Indeed, the mpegts demuxer needs the data to be decrypted before the packet can be decoded and dispatched to the IPMP module.
What would you consider a good architecture for this ? I think that a new module interface would be needed that could be called between the mpd_in reader and the mpegts demuxer.

Although you released gpac 0.6.0 a few days ago, the README.md displayed on the project's homepage still says it's version 0.5.0. So that you don't have to update this file with every version, you may want to remove the version number and date from that file.

```
The reason for the problem is that your Makefiles contain directives like this:
```
$(CC) $(SHFLAGS) $(LDFLAGS) -o ../../bin/gcc/$@ $(OBJS) $(EXTRALIBS) -L../../bin/gcc -lgpac
```
`$(LDFLAGS)` is going to contain linker flags, which could include a directory in which libraries of dependencies may be found. In the case of a default MacPorts installation, that flag is `-L/opt/local/lib`.
The linker looks for libraries in directories in the order specified on the command line. So in this case, it will look for a library in /opt/local/lib first, and only if not found there will it look in the next given location, ../../bin/gcc.
The problem is that if you've just built a new libgpac in ../../bin/gcc, you want to use that. You don't want to use a possibly older version that might already exist in /opt/local/lib.
The solution is to specify flags for local directories like `-L../../bin/gcc` before, not after, flags for system directories like `-L/opt/local/lib`.
I will submit a pull request in a moment.

Hello,
I use mp4box 0.6.0 rev 9. I want to export subtitles with the command:
mp4box.exe -srt 3 "D:\abc.mp4" -out "d:\abc_track3_deu.srt"
The Output-File-Name is but "abv_track3_deu_3_text.srt"
The error is not very critical, but a solution would not be bad.

Hi,
for playback reason, I've changed the container of almost all my avi files to mp4.
in others words, my tv play mp4 files much better than avi files, same content, just container change.
unfortunatelly, I've some file which doesn't play back at all, i.e., the sound is ok, but no images.
they play well using avi container.
the only reason I've found is that these videos have a "custom quant matrix" instead of a h263 standard matrix.
a sample file is located at http://cyrillelefevre.free.fr/tmp/novideo.avi (2Mo, 30sec)
http://cyrillelefevre.free.fr/tmp isn't browsable, that's normal.
remux with mp4box -add novideo.avi#video:lang=fra:timescale=25000:name= -add novideo.avi#audio:lang=fra:mpeg4:name= -new novideo.mp4
also tried without success with ffmpeg -i novideo.avi -vcodec copy -acodec copy novideo.mp4
any ideas to bypass/solve this problem ?
PS : video are played through plex on a TV brand/model LG 55LX5590.

hello,
when I am writing the following command for creating a single mpd file for two different resolution videos, this error is comming. Though the dashinit files and mpd have been created successfully but this mpd is not accepted by my dash player.
the error is " Files have non-proportional track layouts (854x480 vs 640x360) but sample size and aspect ratio match, assuming precision issue "
and the command I am using is :
MP4Box -dash 2000 -rap -frag-rap -profile onDemand -out mpd v480.mp4#video v360.mp4#video v480.mp4#audio
where v480 is 854 \* 480 video and v360 is 640 \* 360
please help me

Hi,
Could you explain clearly the difference between the fps, timescale and rescale options ?
What this really means : !! THIS IS IGNORED FOR IsoMedia IMPORT !!
In others words, when fps doesn't work, when to use timescale instead of fps, etc.
Thanks in advance.

MP4Box mix the **stdout** and **stderr** up when you run the command in a linux terminal.
You can test it by running MP4Box and separating the standard output and the error output into different files, i.e.:
`MP4Box -diso -std sintel_trailer-480p.mp4 > std.out 2> std.err`
The information for that mp4 file should be in the _std.out_ file but in fact the _std.out_ is empty but the file _std.err_ contains the information for the mp4 file, this is the result of the MP4Box command.
It should be in the other way around since no error happens.

Hi,
For some reason, I've converted all my .avi to .mp4.
The most simple way to do it is something like :
- _mp4box -add file.avi#video:name= -add file.avi#audio:name= -new file.mp4_
However, this doesn't work with not mp3 audio files, so I use something like:
- _mediainfo file.avi_ to get some more parameter like fps, video and audio format.
- _mkvmerge -o file.mkv file.avi --compression 0:none --default-duration 0:${fps}fps_
- _mkvextract tracks file.mkv 0:file.$extv 1:file.$exta_ ($extv may be avi of h264, $exta may be aac, ac3 or wma)
- convert file.$exta to file.mp3 if $exta is wma then exta=mp3 using using ffmpeg to 1st convert to wav then lame to convert to mp3
- convert file.$exta to file.aac if $exta is ac3 then exta=aac using neroaacenv
- _mp4box -add file.$extv#video:fps=$fps:name= -add file.$exta#audio:delay=$delay:name= -new file.mp4_
Almost all of these commands where inspired from megui.
Well, the problem is that with .mp3 audio track, in the first case, the audio track look like **soun:mp4a:6b** and **soun:.mp3** in the second case.
Unfortunatelly, my TV doesn't play sound in the second case.
For instance, the way I use to repack the right way is :
- _ffmpeg -i file.mp4 -acodec copy -vcodec copy file-remux.mp4_
Well, an alternative is to encapsulate the .mp3 track in an .mp4 file using ffmpeg too :
- _ffmpeg -i file.mp4 -nv -acodec copy file-audio.mp4_
- _mp4box -add file.mp4#video:name= -add file-audio.mp4#audio:name= -new file.mp4_
Also, this fails with "BitStream Not Compliant" :
- _ffmpeg -i file.mp4 -nv -acodec copy file-audio.avi_
- _mp4box -add file.mp4#video:name= -add file-audio.avi#audio:name= -new file.mp4_
mp4box -info of the first case :

So, the question is... is it possible to obtain a .mp4 with audio looking like soun:mp4a:6b instead of soun:.mp3 when importing .mp3 files directly using a command like this :
- _mp4box -add file.avi#video:name= -add file.mp3#audio:name= -new file.mp4_
Thanks in advance.
Regards.

Hi,
I am trying to stream the video from an IP camera using dash.js,the steps which i have tried is given below:
1.I am using avconv to capture from camera,i am using the follow command:
```
avconv -i "rtsp://[camera-ip-address]:554/mpeg4/media.amp" -vcodec libx264 -vb 1800k -bufsize 3600k -keyint_min 192 -g 192 -vprofile main profile
-acodec aac -ar 48000 -ac 2 -strict experimental -f h264 live_h264_1800k.H264 \-vcodec libx264 -vb 2200k -bufsize 4400k -keyint_min 192 -g 192 -vprofile main -acodec aac -ar 48000 -ac 2 -strict experimental -f h264 live_h264_2200k.h264
```
2.Then i am using mp4box to generated dynamic live .mpd and .m4s
i am using the follow command:
`MP4Box -dash-live 4000 -fps 24 -profile dashavc264:live -dynamic -mpd-refresh 1200 -bs-switching no -dash-ctx $ctxtOut -segment-name dashseg%s -out $pathMpdFile -add live_h264_1800k.h264 live_h264_2200k.h264 live_h264_1800k.mp4 live_h264_2200k.h264
`
3/i am using (1) and (2) in parallel
from dash-if player i am receiving this log(`No muxed data`.) and video does not start:
Please, can you give me some suggestion to solve this issue?
thanks

FFmpeg recently pushed out the 3.0 release, and gpac v0.5.2 seems to have trouble building against it (OS X 10.11.3):

Full logs here: https://gist.github.com/anonymous/2bd2fbada48fb6591d9d#file-02-make. Building master against FFmpeg 3.0 was a success, though.
Therefore, would you please consider cutting a release to address this compatibility issue? This issue is unfortunately blocking FFmpeg 3.0 at [Homebrew](https://github.com/Homebrew/homebrew/pull/49178) (a stable release is required there).

Typically we could open a Smooth Streaming URL. But if it is the mime type is plain/text like in

or

then we return immediately.

Hello.
Seems like there is a problem when muxing .264 files to .mp4 if the original .264 video uses chroma 4:4:4 (8 or 10 bit).
I have a video of 1000x800 resolution uncompressed .avi bgr24 and I did some tests:
.avi to .264 commands after pass 1:
```
x26410.exe ^
--pass 2 ^
--profile high444 ^
--preset slow ^
--output-csp i444 ^
--range pc ^
--fps 30 ^
--sar 1:1 ^
--stats "C:\testshit.stats" ^
--bitrate 6000 ^
--output testshit44410bit.264 "C:\testshit.avi"
```
Using x264 (8 or 10 bit) and using profile (high or high10) and using --output-csp i420:
- .264 video -> no problem
- muxing it with Mp4box -> no problem
Using x264 (8 or 10 bit) and using profile **high444** and using **--output-csp i444**:
- .264 video -> no problem
- muxing it with Mp4box -> **problem** (changes width to 992 and, for example, MPC-HC reports resolution as "1000x800 (RdA 31:25)" 992x800.)
I have tested with mp4box version that comes with MP4boxgui 0606, mp4box rev563 and rev1180 using this commands:
`-add "C:\testshit44410bit.264:fps=30.000:delay=0:name=testshit44410bit.264" -itags tool="My MP4Box GUI 0.6.0.6 blablabla" -brand mp42 -new "C:\testshit44410bit.mp4"`
Latest Mediainfo and x264 18jan2016 version.

When using the following mp4box command:
> MP4Box -dash 5000 -rap -frag-rap -profile onDemand -out video.mp4 audio.mp4
Audio is DTS
The mpd file is output like this:
`<Representation id="6" mimeType="audio/mp4" codecs="mp4a.a9" audioSamplingRate="48000" startWithSAP="1" bandwidth="1512196">
<AudioChannelConfiguration schemeIdUri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="2"/>
<BaseURL>audio_dashinit.mp4</BaseURL>
<SegmentBase indexRangeExact="true" indexRange="902-1653">
<Initialization range="0-901"/>
</SegmentBase>
</Representation>`
The codec seems incorrect and doesn't work with mpeg dash players like Exoplayer (Android).
If I change the codecs="dtsc", everything works fine in Exoplayer.
Is there a reason why MP4BOX isn't putting the codec correctly?

I configured the BufferLength and RebufferLength in the config file in GPAC however it changes automatically as the video is playing.
How do I fix during the entire playback?

I'd like to capture with video "screen-capture-recorder" and audio "microphone" using dashcast.
I am using dashcast for WIN 64 binary.
So, how can I get the information regarding audio
I know that it should be used the option -a plughw:[x],[y]
x is the card number y is the device number.
How can I get the information above in the windows platform..
Thank you so much in advance..

When I execute dashcast command as follows :
DashCast -vf dshow -vres 1280x720 -vfr 24 -v video="WebCam SC-10HDP12631N" -pixf yuv420p -live
I used the latest GPAC win64 binaries.
During encoding dash segments, the CPU usage percentage is extremely high (95%) on my PC.
My laptop PC has Quard-core processor.
Can I divide the load with Quard-core processor during dashcast ?
Thanks in advance.

I'm trying to use the generated dashinit as a backup source from my vod files but when I create the dashinit mp4 with mp4box It seems that the faststart option is missing which I had in the previous file, is there a way to keep the faststart option for progressive download with the mp4box?
Thanks.

I have a video with RAPs at sample 1,301,307,453...
RAP 301 & 307 are close to each other, in the same second.
Split option can adjust only to one of them and choosing RAP 307.
However it's not "true decodable keyframe", that playable is 6 frames before.
Splitted fragment plays with frozen glitch at beginning (from RAP 453 video is playing fine).
If StartTime:EndTime could be defined as double-precision number (like -fps) that could solve the problem, right?

Hello,
I'm new to dashcast and tried to create a pseudo live (from file) and live (from camera) session on the window and linux platform:
DashCast -v /.../inputfile.ts(or mp4) -live-media -out /.../video/ -time-shift 50 -min-buffer 10
or
DashCast -v /dev/video0 -live-media -out /.../video/ -time-shift 50 -min-buffer 10
mpd file and segments files (m4s) were created (see below mpd file). Unfortunely, I got the 100% processor load on windows and 300% on Linux (in the top). For Windows I used the build from your site; for linux I used the instruction from https://gpac.wp.mines-telecom.fr/dashcast/ in order to make the custom build.
I tried to play the the stream on the same computer using "MP4Client dashcast.mpd". Sometimes it played with a picture that sometime ok, sometime unclear, I got often an error message: Error opening new segment v1_xx_gpac.m4s; I checked and indeed there are some gaps between files. Sometimes I got an error message "Something gone terrible wrong, reset the input buffers" on the client side.
When I start a client MP4Client, I got on the producer side (dashcast terminal) error messages:
[h264 @ 0x118f040] reference picture missing during reorder
[h264 @ 0x118f040] reference picture missing during reorder
[h264 @ 0x118f040] Missing reference picture, default is 65568

[h264 @ 0x127e120] reference picture missing during reorder
[h264 @ 0x127e120] Missing reference picture, default is 65576
If I stop a client, it works ok.
The *.ts or mp4 (mp4 was created ffmpeg.exe -c copy -movflags empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof -f mp4 XXX.mp4) files are ok and can be played without problems using vlc or other players. If I do the same mp4box -dash 10000 -segment-name name NHL.mp4; it works fine and fast but I didn't find out how to create a live stream using mp4box from stream. What is the preferred program to create live sessions?
As I understand, the conversion from .ts(mp4) is just the container format changes and should be not processor intensive. Therefore, my question is: what I do wrong or which configuration I missed?

While attempting to do ClearKey encryption of a ts file, MP4Box crashes with Segfault 11. If this particular combination of container, encryption and codec is not supported, I would have expected an error message, rather than a segfault.

When using batch files it is inconvenient to have to set -sbr for certain files, or having to use separate batch files.
Is it not possible for mp4box to determine if the audio file is ADTS/HE-AAC?
Noticed I couldn't mux and .h264 and an .aac, later learned about the -sbr option.

I assume it's caused by colrnclc field before stts at beginning of the file, injected by HandBrake.
Old mp4box (0.5.0) is smart and skip this, allowing working on such files, while new builds can't handle this...

I am interested in understanding if mp4box supports hardware-accelerated AES. In a sense, I am asking "Is it possible to make mp4box -crypt faster" but I imagine hardware acceleration is the main method to accomplish this.
The scenario in question is one where we might have a large amount of data that needs to be encrypted on the fly - obviously, very good performance would be needed from the encryption process in such a scenario.
If it does not currently use hardware-accelerated AES such as AES-NI, is it technically compatible? I am not familiar with how the hardware accelerated AES instructions work, so I wonder if what I ask about is perhaps impossible.

DASH uses the en-US variant of language codes and thus, I wish to add such codes (either en or en-US style) to my tracks. Indeed, mp4box operates quite correctly when I do so with `mp4box -lang 1=en myfile.mp4` and I have no issues with the output.
However, it generates this dangerously misleading message during operation:
```
The given code is not a valid one: es, using 'und' as 3-letter code
```
I am not at all interested in the 3-letter codes but users viewing the operation logs now think that something is broken. Having this "error" message is undesirable for me. If possible, it would be nice to have some mode of operation that ignores the 3-letter language codes in its diagnostic output (and actual operation).

Hi,
I'm using GPAC 0.5.0+svn5324~dfsg1-1+b3 on Debian 8.1
When i try to create a MP4 file, MP4Box don't keep the input framerate, but it set 25 fps per default.
I can pass the parameter -fps to have a proper file (and avoid a desync audio/video), but according to the documentation, without argument the framerate of the input file should be kept :
-fps FrameRate
overrides the input video frame rate or specifies it for SUB subtitles.
Is there a workaround or a way to keep the input framerate when creating a MP4 file ?
Thanks !

If I run a DASH segment I grabbed from YouTube through `MP4Box -info`, I get
```
File Brand dash - version 0
```
Checking that same file with `ffprobe`, I see:
```
major_brand : dash
minor_version : 0
compatible_brands: iso6avc1mp41
```
With DASH segments produced using `MP4Box`, the former gives me:
```
File Brand iso5 - version 1
```
and the latter
```
major_brand : iso5
minor_version : 1
compatible_brands: avc1iso5dsmsmsixdash
```
My files seem to be playing fine, but I was just wondering if there's an elegant way to override the fourcc when using `MP4Box -dash`, and if it would make sense to replace `iso5` with `dash`.
[The docs](https://gpac.wp.mines-telecom.fr/mp4box/mp4box-documentation/) say MP4Box's `-add` lets you append `:stype=4CC`, but in order to use that, it looks like I'd have to transmux the files that `MP4Box -dash` produces in a postprocessing step, correct?

First I'd like to make tests so that people can take and run a GPAC player from wherever they are (no download available, practical sessions).

Widevine Modular
I've created test video and test audio. I can confirm that the video plays correctly in dash.js if dashed ondemand with MP4Box. If I add Widevine encryption to both the audio and video and re-dash using MP4Box the content does not play. It fails to identify the required DRM key system in parsePSSHList. However, if I add ContentProtection elements containing the DRM system ID and PSSH data into both adaptionsets in the MPD the DRM system is correctly identified as com.widevine.alpha and a call made to the license server.
When examining demo mpd files from Cablelabs, BitDash I notice that the PSSH data within their MPD files contains elements according to the Widevine CENC header https://html5.cablelabs.com/mse-eme/doc/creation.html#encryption, but the example PSSH found here https://github.com/cablelabs/mse-eme/tree/master/create/encrypt/widevine/cryptgen only contains key Id, content Id and track type.
I've attempted to use PSSH data from Cablelabs/BitDash (PSSH containing the system id) in my own MP4Box encryptions without additional contentprotection elements in the MPD, but this fails in the same way as PSSH boxes that do not contain the system id.
Failure is that the content does not play. There are no errors in the console and no trace that a DRM key system has been selected (as mentioned the parsePSSHList dash.js function fails)
The only way I can progress is by putting contentprotection elements into the adaptionsets that contain the system id and PSSH data.
It appears that MP4Box isn't adding the correct DRM info to the content headers when using Widevine PSSH boxes. However, it appears to correctly assign PlayReady PSSH boxes.
Is this a known issue, with the workaround being the one I've already found?

I tried to build on Ubuntu 14.04 by following these instructions:

Still points to the old SVN repo in sourceforge etc.

It's possible to set a notification in the sourceforge page indicating that the project has moved to GitHub. Example here: http://sourceforge.net/projects/dustrac/

Hi all,
I have a poorly encoded video of a webcast (I presume it came from a WebEx screencast) and the main issue is that the framerate of the mp4 file is double than it should be. If I play it with VLC and slow down the playback speed to 0.5x, everything's normal and I can understand the audio. If I play it at 1x, I can't understand anything and everything's too fast.
Framerate reported by MediaInfo and ffprobe is 10fps.
My first stab at this problem was to use mp4box to change the framerate to 5fps. I actually succeeded at "slowing" down the video but I failed at slowing down the audio. Here's what I tried:
```
$ mp4box -add source.mp4\#video -raw 1 -new video
```
this created "video_track1.cmp" file.
```
$ mp4box -add source.mp4\#audio -raw 2 -new audio
```
this created "audio_track2.aac" file.
I then tried combining them with:
```
$ mp4box -add video_track1.cmp:fps=5 -add audio_track2.aac:fps=5 -new output.mp4
```
This actually partially worked and produced a output.mp4 that had video portion correct and it played at the right speed but the audio was still playing too fast. Duration of the audio track in output.mp4 was exactly 1/2 of the duration of the video track. So the `:fps=5` part did not affect the audio track at all.
How do I fix the audio track? I don't mind re-encoding it with ffmpeg if that's the only option. I actually did try to slow down the audio track by re-encoding with ffmpeg but it sounded horrible and audio had an echo. Slowdown with VLC sounded perfect however.
```
$ ffmpeg -i out.m4a -filter:a "atempo=0.5" -vn outputaudio.aac
```
What am I doing wrong?
|
When changing framerate of a video, how do you change audio track's rate as well?

hi,
I'm testing DASH live streaming under windows 7 64bit using
> gpac-0.5.2-DEV-rev1110-g9f2bf6e-master-x64
first I use mp4box with command line:
> mp4box -dash-live 10000 -mpd-refresh 6 -out {dir}\test.mpd -bs-switching no track1.mp4
then I use mp4client with command line:
> mp4client {dir}\test.mpd
I can see the movie playing, but after a little while, it would start to stutter, then simply freeze afterwards...
from console I see log like:
> [IsoMedia] Error opening new segment URL {dir}/track1_dash37.m4s at UTC 1453187376867: Requested URL is not valie or cannot be found
> [IsoMedia] Error opening new segment URL {dir}/track1_dash38.m4s at UTC 1453187376867: Requested URL is not valie or cannot be found
> [IsoMedia] Error opening new segment URL {dir}/track1_dash39.m4s at UTC 1453187376871: Requested URL is not valie or cannot be found
I thought my use case is basic and nothing special, but still met lots of problems to deal with...
help needed please...

When I try to dump a text track from a mp4 file recorded by my dashcam (it stores gps-data and g-sensor data in a text track) with MP4Box version 0.5.2-DEV-rev1127, it fails.

Using the GUI tool YAMB to dump the track it generates a correct srt file. YAMB uses MP4Box version 0.4.6-DEV with exactly the same command as above.
Am I missing something obviuos? Or is this a bug?
