Many dash streams meant to be run on PC or mobile devices use a separate init and segment files per each bitrate stream. It is easy to understand, transcodings may run clustered, easy to text edit manifest.mpd file to create new test case. Just add new or remove bitrate representations in a xml file.
HbbTV specification (unfortunately) chose to use a shared init.mp4 file where 1..n TRAK/MDIA/MINF/STBL/STSD/AVCx objects are embedded in a same file, thus introduce a dependency between each bitrate stream in a manifest file. This is bs-switching=multi in gpac documentation. https://gpac.wp.mines-telecom.fr/mp4box/dash/
Complicates a clustered transcoding use, no easy text edit to change bitrate representations. Changing number of representations require to create a new init.mp4 binary file. I have this exact problem.
Source manifest has separate init-vX.mp4 per each bitrate representation. I could create a script to download multiple init segment files and run "merge init segments (video, audio)" action. Possible with mp4box without actual data payload video files?
Or is it each seg-v1_001.mp4, seg-v1_002.mp4, seg-v2_001.mp4, seg-v2_002.mp4 payload segments must sample_description_index(0..n) reference to an appropriate init.mp4 STSD/AVCx object array? If that is the case then no simple runtime script is possible.
|
Create single-init.mp4 from separate init-v1.mp4, init-v2.mp4 so on?

Hi there,
At present, when dashing protected content with MP4Box, it uses the generic identifier "urn:mpeg:dash:mp4protection:2011" within the generated MPD playlist for element ContentProtection, attribute @schemeIdUri.
This value is currently hardcoded in the following function:
https://github.com/gpac/gpac/blob/master/src/media_tools/dash_segmenter.c#L630
Some vendors use different ContentProtection identifiers that are detailed here:
http://dashif.org/identifiers/protection/
In our case, we're using Widevine, and whilst the majority of clients and players are happy with the generic identifier, some clients such as Chromecast require it set to "edef8ba9-79d6-4ace-a3c8-27dcd51d21ed".
I managed to work around this in our case by simply recompiling libgpac with the Widevine identifier, but it'd be awesome if there was a feature in mp4box to allow the schemeIdURI to be specified on the command line.
Hopefully this feature request would be useful for other users of gpac, and a nice addition to mp4box's repertoire.
Kind regards,
Gareth

Hi!
In #234, one issue with MP4Box was detected: https://github.com/gpac/gpac/issues/234#issuecomment-139476108.
The media can be found here: http://1drv.ms/1JPg0t8 (in the eDash folder).
So, the problem is that when using the `mp4box.exe -info`, it shows that the movie duration and the track duration are zeroes, although the media itself contains non-zero information. For example, this is what MP4Box shows (see: /eDash/mp4box.info.video.txt):
```
* Movie Info *
Timescale 12288 - Duration 00:00:00.000
1 track(s)
Fragmented File: yes - duration 00:00:52.208
27 fragments - 1 SegmentIndexes
File suitable for progressive download (moov before mdat)
File Brand dash - version 0
Created: GMT Tue Sep 08 11:00:56 2015
Modified: GMT Tue Sep 08 11:00:56 2015

Fragmented track: 1253 samples - Media Duration 00:00:52.208
Visual Track layout: x=0 y=0 width=640 height=360
MPEG-4 Config: Visual Stream - ObjectTypeIndication 0x21
AVC/H264 Video - Visual Size 640 x 360
AVC Info: 1 SPS - 1 PPS - Profile High @ Level 3
NAL Unit length bits: 32
Pixel Aspect Ratio 1:1 - Indicated track size 640 x 360
SPS#1 hash: 4CB56C454FE3B93E30D7D2B6425805D02E55BD2D

Self-synchronized
RFC6381 Codec Parameters: avc1.64001e
No sync sample found
```
And that's what the media contains (see: /eDash/mp4dump.video.txt):
``` javascript
{
"name":"mvhd",
"header_size":12,
"size":108,
"timescale":12288,
"duration":641536,
"duration(ms)":52208
}
```
``` javascript
{
"name":"tkhd",
"header_size":12,
"size":92,
"enabled":1,
"id":1,
"duration":641536,
"width":640.000000,
"height":360.000000
}
```
Expected behavior: MP4Box must show correct durations.

When I play the live stream which product by the dashcast in dash.js player. I found that the dash.js player can not product right segment number.
Such as the dashcast is producting the segement 10. But the dash.js are requesting the segment 97.
This means that the dash.js can not calculate right number of the segment according the MPD file.
Here is my command.
D:\wamp\www>DashCast -vf dshow -vres 1280x720 -vfr 24 -v video="screen-capture-recorder" -live -npts -low-delay -mpd-refresh 2
I hope that you can help me.

Run dashcast once without -low-delay. This will create dashcast.conf with low-delay=no
Run dashcast again with -low-delay in the command line. The low-delay is ignored because the configuration file is used.
Command line parameters should override the configuration file, not the opposite.

Latest MP4Box -dash creates out_{intputfilename}.mp4 files. But the path creation is broken for instance when the input path is absolute:
`out_/full/path/to/input.mp4` for an input at `/full/path/to/input.mp4`
If only relative input paths are allowed, then this should be clearly documented, although I'd consider it a seriously lacking feature.

hey
little feature request that could be helpful.
I'm building a docker container with gpac (among other things) but I cannot find a link to the **latest nightly build**, e.g. from [this page](http://download.tsi.telecom-paristech.fr/gpac/latest_builds/linux64/gpac/) I can see the list of builds with commit hashes but no link to something like _gpac_0.5.2-DEV-latest.deb_ that would be quite handy to implement CI on our side.
would this be something reasonably easy for you to add? I think it would be useful!
thanks!

The player should support the [ClearKey DRM system](https://w3c.github.io/encrypted-media/#clear-key) as defined by the W3C EME Spec. Some documentation is available by Cable Labs [here](https://html5.cablelabs.com/mse-eme/doc/creation.html#encryption) and a tool to generate the ClearKey crypt file is [here](https://github.com/cablelabs/mse-eme).

It should be possible in the GUI of MP4Client to select which audio track to play when there are multiple tracks. Ideally information such as language (from the track header and the extended language box), kind (from the kind box), and other metadata should be exposed to make the choice. An example file is : http://perso.telecom-paristech.fr/~concolat/html5_tests/count_audio.mp4

The current options for splitting a file are:
```
-split time_sec splits in files of time_sec max duration
* Note: this removes all MPEG-4 Systems media
-split-size size splits in files of max filesize kB. same as -splits.
* Note: this removes all MPEG-4 Systems media
-split-rap splits in files beginning at each RAP. same as -splitr.
* Note: this removes all MPEG-4 Systems media
-split-chunk S:E extracts a new file from Start to End (in seconds). same as -splitx
* Note: this removes all MPEG-4 Systems media
-splitz S:E same as -split-chunk, but adjust the end time to be before the last RAP sample
* Note: this removes all MPEG-4 Systems media
```
There is no way to split with a given duration but with alignment to RAPs, similar to DASH segmentation.

Hi,
We use MP4Box to encrypt MP4 files and then use MP4Box to generate MPD. It worked very well. We recently met an performance issue on one device when playing encrypted MPEG-DASH stream. So we would like to try to encrypt key frames (RAP) only instead of all samples.
According to the [documentation](https://gpac.wp.mines-telecom.fr/mp4box/encryption/common-encryption/), we add selectiveType and set it to "RAP". There is no error when calling MP4Box -crypt, but segmentation fault occurred when calling MP4Box -dash.
Could someone help this?
Thanks,
Wesley

Hi!
While creating DASH on-demand media using MP4Box (GPAC version 0.5.2-DEV-rev575-geedd2f0-master) for some iOS media player, I noticed following issues:
- The video playback speed is wrong. Depending on media, it may be either too fast or too slow. At the same time, the audio plays (sounds) at its normal speed.
- The timeline of the media player is broken. The media player shows it like there's a lot of content. So, when the media ends, there's still a lot of space to the right.
What's interesting, Google's eDash packager (https://github.com/google/edash-packager) produces DASH media that plays correctly. This points to the fact that MP4Box is doing something wrong. I've tried to find out what may cause such issues, and I noticed following issues in MP4Box. Test media with logs can be found here: http://1drv.ms/1JPg0t8. (I also use mp4dump for inspecting media, which comes from Bento4.)
1. After dashing the media, durations of the movie ('moov/mvhd') and the track ('moov/trak/tkhd') are being reset to 0. You may see it in /MP4Box/mp4box.info.video.txt and /MP4Box/mp4dump.video.txt. The media player that I use uses this information, and because of that is not able to display the timeline correctly. In the /Source folder, you may see logs that show that before dashing in MP4Box, durations are present.
2. "MP4Box -info" with eDash media, looses durations mentioned in (1). You can see it by looking at /eDash/mp4box.info.video.txt. This seems like another bug in MP4Box, because the /eDash/mp4dump.video.txt shows that durations are there. So, it's just MP4Box shows them as zeroes.

Because it could be called from a different file. A different timescale leads to an error. So we need to error.

When trying to compile x264 against gpac, unless you build gpac as `--static-mp4box` then x264 complains that the gpac version is too old, but by doing this, then the OpenGL support is no...
How do we get OpenGL support in gpac and compile it also against x264 without it complaining?

Hi,
Why I can not get a right segment with dashcast.
I have tried many machines, such as windows 7 64 bit, ubuntu 14.04.
Now, I can not get a right segment which can be played by dash.js.
I want know will the tool no longer be maintained?

Currently, I am working on DASH area.
I need to print the bandwidth of each segment and the remnant buffer time at that time.
I struggled in the source code for 2 days. And I can only print the bandwidth now....
I found a function in dash_client.c
```
gf_dash_set_user_buffer
```
which set the value of 'user_buffer_ms', but it isn't called during the whole process.
Anybody can help me?
Thank you~

I am attempting to transcode and DASH (with Clear Key encryption) a [sample H.264](http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_h264.mov) file for the Osmo4 or [Google Shaka](https://github.com/google/shaka-player) players. Every set of steps I've been able to piece together online results in a playable version if unencrypted, then breaks down when I attempt to layer in encryption.
### Unencrypted
Here are the steps I follow for the working unencrypted version:
1. Separate video from audio
```
ffmpeg -i input.mp4 -an -c copy video_only.mp4
ffmpeg -i input.mp4 -map 0:2 -c copy audio_only.m4a
```
2. Transcode the video into a working variant (only 1 for now)
```
ffmpeg -i video_only.mp4 -an -vcodec libx264 -s 1280x720 -c:v libx264 -b:v 384k -bf 2 -g 90 -sc_threshold 0 -an -strict experimental video_only_384kbps.mp4
```
3a. Create the mpd
```
MP4Box -dash 5000 -segment-name 'outputseg-%s' -url-template -bs-switching no \
-out output.mpd -rap \
audio_only.m4a \
video_only_384kbps.mp4
```
4a. Load the video into Osmo4 or Google Shaka
It plays.
### With Encryption
Now, I attempt to layer in encryption. Starting from after step 2 above:
3b. Encrypt the variants with Clear Key
```
MP4Box -crypt drm.xml audio_only.m4a -out audio_only_encrypted.m4a
MP4Box -crypt drm.xml video_only_384kbps.mp4 -out video_only_384kbps_encrypted.mp4
```
where drm.xml contains a sample derived straight from the [MP4Box/GPAC site](https://gpac.wp.mines-telecom.fr/mp4box/encryption/common-encryption/):
```

</CrypTrack>
</GPACDRM>
```
4b. Create the mpd
```
MP4Box -dash 5000 -segment-name 'outputseg-%s' -url-template -bs-switching no \
-out output.mpd -rap \
audio_only_encrypted.m4a \
video_only_384kbps_encrypted.mp4
```
5b. Load the video into Osmo4 or Google Shaka.
- On Osmo4, no errors are found but the player just hangs until I kill it
- On Google Shaka, I consistently receive a player error:
"CustomEvent {detail: Error: No DrmInfo exists!
at shaka.media.EmeManager.buildKeySystemQueries_ (http://localhost:808…, srcElement: null, target: s…a.p…r.Player, currentTarget: s…a.p…r.Player}
The output.mpd after 5b looks like this:

I'm using the "splitz" option of mp4box to trim mp4 files. From what I've seen so far, and how I interpret the documentation, the expected behavior is to adjust the end time backwards if needed. I have files at varying frame rates, namely 30000/1001 (29.970fps), 15000/1001 (14.985fps) and 10000/1001 (9.990fps). Whenever I specify an endpoint of "87", the files at 14.985fps and 29.97fps adjust correctly back to the previous point at 84.08 sec, however the file at 9.990fps moves forward to 87.09 sec.
The following example using big buck bunny encoded at the rates listed above illustrates the issue:
```
$ mp4box -splitz 15:87 in/bbb_9.990fps.mp4 -out out/bbb_9.990fps_splitz_15_87.mp4
Adjusting chunk start time to previous random access at 12.01 sec
Adjusting chunk end time to previous random access at 87.09 sec
Extracting chunk out/bbb_9.990fps_splitz_15_87.mp4 - duration 75.08s (12.01s->87.00s)
Warning: Edit list doesn't look like a track delay scheme - ignoring
$ mp4box -splitz 15:87 in/bbb_14.985fps.mp4 -out out/bbb_14.985fps_splitz_15_87.mp4
Adjusting chunk start time to previous random access at 12.01 sec
Adjusting chunk end time to previous random access at 84.08 sec
Extracting chunk out/bbb_14.985fps_splitz_15_87.mp4 - duration 72.07s (12.01s->87.00s)
Warning: Edit list doesn't look like a track delay scheme - ignoring
$ mp4box -splitz 15:87 in/bbb_29.970fps.mp4 -out out/bbb_29.970fps_splitz_15_87.mp4
Adjusting chunk start time to previous random access at 12.01 sec
Adjusting chunk end time to previous random access at 84.08 sec
Extracting chunk out/bbb_29.970fps_splitz_15_87.mp4 - duration 72.07s (12.01s->87.00s)
Warning: Edit list doesn't look like a track delay scheme - ignoring
```
Using an endpoint of 86 (or 88) moves backwards properly as do many other values.
Source and output files used in this example can be found at https://www.dropbox.com/s/4yj6iu19yeh3xei/mp4box-splitz-issue.zip?dl=0
I'm using the following version of mp4box under 64 bit windows 7 - MP4Box - GPAC version 0.5.2-DEV-rev575-geedd2f0-master
Please let me know if I can provide any additional information. Thanks!

Trimming with mp4box splitz moves forward instead of back at end point for low frame rate

When looking at attached DASH-contexts, for the audio 128k I get:
```

=> 3956 is incorrect, we expect 3989 (i.e. the closest value to 4000)

Hi,
everyone.
I have used dashcast(GPAC) to create my dash content. MP4Client plays them fine.
I am trying to play them using the dash.js reference player. But I recieved this result:
I use the command

Issue migrated from [here](http://sourceforge.net/p/gpac/bugs/351/).
- Files are not created under base url, but in current directory:
``` sh
$ mkdir base
$ MP4Box -dash 10000 -base-url 'base/' -segment-name '$RepresentationID$-$Number$' -url-template -out test.mpd test.mp4#audio test.mp4#video
$ ls -1 base
$ ls -1 | wc -l
125
```
- prefixing segment name with base url result in files created in correct directory, but base url must then be removed from the `media` and `initialization` attributes of the SegmentTemplate tag:
``` sh
$ MP4Box -dash 10000 -base-url 'base/' -segment-name 'base/$RepresentationID$-$Number$' -url-template -out
test.mpd test.mp4#audio test.mp4#video
$ ls -1 base | wc -l
122
$ ls -1
base
test.mp4
test.mpd
$ fgrep RepresentationID test.mpd
<SegmentTemplate timescale="44100" media="base/$RepresentationID$-$Number$.m4s" startNumber="1" duration="440294" initialization="base/$RepresentationID$-.mp4"/>
<SegmentTemplate timescale="19200" media="base/$RepresentationID$-$Number$.m4s" startNumber="1" duration="192000" initialization="base/$RepresentationID$-.mp4"/>
```
With more than one video input, the set init file is still created in the current directory and must be moved into the base url directory.
|
MP4Box -base-url has no effect on file creation

Hi We used MP4Box to genreate mpd and segment-ed dash files
Command used was:
MP4Box -dash 2000 -rap -frag-rap -profile onDemand -out /eph/974792159628123000/a/613992915/v/752033447846770000_100/dash.mpd /eph/974792159628123000/a/613992915/v/752033447846770000_100/xq.mp4#video /eph/974792159628123000/a/613992915/v/752033447846770000_100/xq.mp4#audio /eph/974792159628123000/a/613992915/v/752033447846770000_100/hq.mp4#video /eph/974792159628123000/a/613992915/v/752033447846770000_100/mq.mp4#video /eph/974792159628123000/a/613992915/v/752033447846770000_100/lq.mp4#video
When we play the mpd in the GPAC sample player (and even in our own own implementation in flowplayer 6.0.3)
It results in buffer stalling between 7/ 13 seconds (it varies).
The mpd url is:- https://s3.amazonaws.com/dev.media.burst.it/a/613992915/v/752033447846770000_100/dash.mpd
Tried it in this sample player:- http://dashif.org/reference/players/javascript/1.4.0/samples/dash-if-reference-player/index.html
Also tried it in our own player here-
https://dev.burst.com/test/videoplayback/inbuilt.html
In both case we it results in same results.
Note to see the issue use chrome and if the entire video plays perhaps reload browser and retry.
Can someone tell me what is wrong? From the flowplayer developers they said the mpd is incorrect.
However we are using MP4Box so how can it be incorrect unless there is a bug.
MP4Box is fairly recent and compiled from github
See below-

I am attempting to play an MPEG-2 TS multicast stream with the Mac OSMO4 player. I enter the URL (udp://233.3.3.197:30120) on the playlist. As soon as I select it from the playlist, OSMO4 crashes.
Running OS X 10.10.5, have tried the two most recent dailies:
gpac-0.5.2-DEV-rev552-g5a1b427-master
gpac-0.5.2-DEV-rev553-gfb86514-master
I also tried on 10.8.5, but there OSMO4 crashes on launch.
The stream I'm testing with is a well known MPEG-2 TS with H.264/AAC payload. It plays fine in VLC. Ultimately, I'm needed to receive a 4K HEVC TS, but small steps first...

I am new to the DashCast. I want to use DashCast to stream live video from a webcam. After installation with the instructions from https://gpac.wp.mines-telecom.fr/dashcast/, I tried with the first example
DashCast -vf video4linux2 -v4l2f mjpeg -vfr 30 -vres 1280x720 -v /dev/video0 -conf dashcast.conf -live
But it failed with the following message:
[libx264@0x7f52380000920] AVFrame.format is not set
[libx264@0x7f52380000920] AVFrame.width or height is not set
[libx264@0x7f52380000920] AVFrame.format is not set
[libx264@0x7f52380000920] AVFrame.width or height is not set
.......
I have tried to tune some parameters, e.g. codec from mjpeg to yuyv422, resolution from 1280x720 to 960x540, etc. Neither works around. Can anyone help me there? Is there more online documentation about DashCast?
Many thanks in advance
David

Hi there, I'm trying to log dash buffering event, meaning the event when the video stream buffer is depleted and the playback is paused due to re-buffering.
Is there any way to log those events, they usually appear in the console this way:
<Buffer : | ============= | (10/100) >
etc.
guess its showing that 10% of the current segment are buffered already.
However I'm especially interesed in how long those buffering events are and if there are any logtools already logging this in a better way than the raw realtime console output.
For example -logs dash@debug will always show me:
[MPD_IN] Had to wait for 0 ms for the only cache file to be downloaded
[MPD_IN] Waited 0 ms - Elements in cache: 1/3
Cache file name gmem://584026@0xa64690
segment start time 0 sec
However 0ms seems rather short right ;-)
Also the Player option -log-utc doesn't seem to work.
The cache logtool also doesn't seem to give me any viable information about the actual video stream buffering happening.
If I had to write my own log tool where I should start if I'd want to log re-buffering events, like logging the time the player has to pause?
ps: I'm still using version 0.5.1-DEV-rev5265M , don't know if anything has changed in newer versions

Hello,
I am generating dash content for HEVC live service using MP4Box. The input video representations has different resolutions, but only one initialization segment has been generated. This shouldn't be the case since init segment contains video width and height parameters, which should be different for each of these representations.
The different representations are created using ffmpeg, example:
ffmpeg -i ~\ContentSources\big_buck_bunny_1080p_surround.avi -f mp4 -vcodec libx265 -s 512x288 -aspect 16:9 -b:v 500k -an -maxrate 504k -bufsize 1004k -threads 0 -x265-params no-open-gop=1:min-keyint=48:scenecut=0:keyint=48 -y ~\ContentSources\bbb_288p_500k_H265.mp4
Then dash content creation using MP4Box,
MP4Box -dash 2000 -profile live -rap -frag-rap -url-template -out ~\Dashcontent\BBB_MultiRes_Multirate_HEVC_Live.mpd -segment-name %s_ -segment-ext mp4 ~\ContentSources\bbb_288p_500k_H265.mp4 ~\ContentSources\bbb_432p_1000k_H265.mp4 ~\ContentSources\bbb_720p_2000k_H265.mp4 ~\ContentSources\bbb_64k_audio.mp4
The common init segment shows size parameters as 512x288.
Also I am using Ubuntu 12.04.5 LTS,
ffmpeg version N-74299-g8db0f71 built with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)
MP4Box - GPAC version 0.5.2-DEV-rev552-g5a1b427-master

I'm trying to capture desktop and stream it live in an Apache server using DashCast. It captures and plays correctly when I do it on demand, however when I do it live and then play with MP4Client it shows only a black screen, not even getting any error message while capturing it. The commands I’m using are:
DashCast -vf x11grab -vres 1280x720 -v :0.0 -npts -live -out /public_html/
And then I play with:
MP4Client http://localhost/vitor/dashcast.mpd
Which results in the following output:
MP4Client http://localhost/vitor/dashcast/dashcast.mpd
Using config file in /home/vitor directory

So what am I doing wrong? The client apparently connects correctly to the server, open the player but then it doesn't show anything on screen. I'm using Ubuntu 14.04 with GPAC version 0.5.0.

@grudelsud and I are using MP4Box `0.5.1-DEV-rev4065` in two environments: OSX 10.10.4 and Ubuntu 14.04.3 LTS. When DASHing the same input file using the same command, the DASHed output on OSX works in [this Shaka Player demo](https://shaka-player-demo.appspot.com/) but the file DASHed on Ubuntu fails in the same Shaka Player demo.

If you diff the MPDs, you'll see that they claim to be from the same version of MP4Box, but there are obvious differences between the two (most notably the `indexRange`).
Please let us know if we can provide you with any further info, and of course any advice would be much appreciated!

It seems mp4box requires the default namespace for TTML to be set:
```
XML (Subtitle, Metadata or Text) SampleEntry: namespace is mandatory. Abort.
```
It seems mp4box expects xmlns="http://www.w3.org/ns/ttml" to be set, although it is also valid to use prefixes on the elements e.g.:
xmlns:tt="http://www.w3.org/ns/ttml" and tt:styling throws up an error.
It should not be the case as from XML specification.

I've currently the issue that when adding an AC3 audio track to a mp4, it runs endless until my disk is full!
Please download the test material and try to bring both tracks (one h264 video and the ac3 audio) together (https://www.dropbox.com/sh/2m4nxqyw6fcjok9/AAA3CGhqUlCTAESzcbOvR2_Ea?dl=0). For this I'm executing the following command:
```
./MP4Box -add American_Beauty_15.07.25_23-55_orf1_110_TVOON_DE.mpg.HD_video.h264 -add American_Beauty_15.07.25_23-55_orf1_110_TVOON_DE.mpg.HD.ac3 -inter 500 -new out.mp4
```
I was also successfully using an mp3 audio track.
The really bad thing is that it runs endless until no more free disk space is available!

Hi Team,
I am executing Mp4Box as part of my C# application.
In some random execution it creates wrong XML syntax of MPD. Please find attached screenshot of one of the invalid MPD. Seems to be there is a bug when it tried to write the final MPD.
MP4Box Command (sample): mp4box -rap -url-template -frag 2000 -dash 5000 -segment-name wild_%s -bs-switching merge 1000000037_2464.m4v 1000000037_1264_enc.m4v 1000000037_864_enc.m4v 1000000037_264_enc.m4v audio_enc.m4a
Please let me know what could be the reason of this. I am using following code to invoke the process.
Dim standardOutput As New System.Text.StringBuilder
Dim standardError As New System.Text.StringBuilder
myProcess = New System.Diagnostics.Process()
myProcess.StartInfo.FileName = Command
myProcess.StartInfo.Arguments = Params

Any idea why?

Hello Guys!
I've just installed GPAC on my Ubuntu. I've tried DashCast with the sample code you provided: DashCast -av test.mp4 -seg-dur 1000 -frag-dur 200
It starts working frame by frame, but after a while it stops and says:
Segmentation fault (core dumpled)
Can you help me with this error?
Thanks,

#### I have noticed that A/V assets transcoded with `FFMPEG` and boxed with `MP4Box` using the `dashavc264:onDemand` profile will have an extremely short initial audio segment (in the range of 1/100th of a second), which will in turn cause the HTML 5 [DASHIF](http://dashif.org/reference/players/javascript/1.3.0/samples/dash-if-reference-player/) and [Akamai reference](http://mediapm.edgesuite.net/flash-client-dev-builds/nightly/dash/v1.0/dash-support-player/index.html) players to fail to play correctly.
##### One must move the "progress" knob a second ahead to get it to play, _after which all is fine_.This issue only seems to occur on Chrome and Internet Exploder, and not the Firefox devkit.
This question [is likely related to this thread](http://sourceforge.net/p/gpac/discussion/287547/thread/b7337740/?limit=25). However, it is different enough to be it's own.
My guess here is the the runt initial audio segment is to preserve A/V sync when rate transcoding from variable input rate to a fixed frame rate of 30fps. It is unclear to me who is generating this initial audio segment: MP4Box or FFMPEG. It is also unclear to me if this is the fault of the `FFMPEG`/`MP4Box` toolchain, or the Media Extension toolkit on Chrome.
However, this problem has been reproduced with a home-grown DASH player, leading one to believe that there may be an incompatibility with the FFMPEG/MP4Box suite and the Chrome and IE HTML 5 players.
##### Thus:
- If this an FFMPEG/MP4Box issue, does anyone know how to prevent the runt initial audio segment from being generated? Or is it a strict requirement?
- If this is a bug in Chrome, is there any way to work around this, short of having one's homegrown player skipping 0.02 seconds into the stream (which is what is currently done)?
#### Specifics:
- HTML5/Media Extensions-based Player on Chrome
- Reference DASH Players:
```
http://mediapm.edgesuite.net/flash-client-dev-builds/nightly/dash/v1.0/dash-support-player/index.html
http://dashif.org/reference/players/javascript/1.3.0/samples/dash-if-reference-player/
```
- Files transcoded with:
(Only one resolution shown here: other resolutions use different video bitrates)
```
ffmpeg -i <file>
-vf <scale stuff>
-r 30 (fixed frame rate of 30FPS. Incoming framerate MAY be variable, and is likely NOT 30fps)
-c:v libx264 -b:v 3000k -profile:v high -pix_fmt yuv420p
-c:a aac -b:a 192k (perhaps using FFMPEG's aac encoder is a bad idea?)
-movflags +faststart
-fflags +genpts (unsure if this is necessary, doesn't seem like a bad idea)
-x264opts keyint=150:min-keyint=150:scenecut=-1 (ensure a fixed 5 second GOP size)
<outfile.mp4>
```
- Files boxed with the following command. Note that I am I only generating a single audio stream:
```
MP4Box -out dash.mpd
-dash 5000
-frag 1000 -frag-rap
-rap
-bs-switching no
-dash-profile dashavc264:onDemand
1080.mp4#video:id=VIDEO-1080
720.mp4#video:id=VIDEO-720
480.mp4#video:id=VIDEO-480
360.mp4#video:id=VIDEO-360
720.mp4#audio:id=AUDIO-192k
```
- Things that _didn't_ work:
- turning genpts on or off
- turning frag and frag-rap on or off
- turning movflags on or off
- switching between `dashavc264:onDemand` and "plain old" `onDemand` profiles
- A/V DASHd asset that DOES experience the problem:
```
http://pm1playscdntv-a.akamaihd.net/video/AKKxcjxr0AE/processed/dash.mpd
```
- Silent jellyfish video that does not experience the initial lockup:
```

```

I'm new to dash and trying to use DashCast to transcode a local live mpegts udp stream. When trying the following command:
```
dashcast -av udp://@127.0.0.1:9998?fifo_size=100000 -live-media
```
I get the following log:
```

```
1. The **circular_buffer_size** error requires a pthread-enabled ffmpeg library. Is that something that can be fixed? Does that mean that udp input cannot be used on Windows?
2. Any idea why it **cannot open input video**? It looks like it did find the video (Stream #0:0[0x1ff] from Program 3)
Regards,
Fred

I am working with MP4/AAC 7.1ch file which is based on "ISO/IEC 14496-3:2009/Amd.4:2013".
When remuxing a 7.1ch MP4 file which have correct "audioProfileLevelIndication" value,
the remuxed MP4 file always have 0x2A for audioProfileLevelIndication (which means 5.1ch).
e.g.
mp4box -add original_7.1ch.mp4#audio -new remuxed_7.1ch.mp4
original_7.1ch.mp4: audioProfileLevelIndication=0x50
remuxed_7.1ch.mp4: audioProfileLevelIndication=0x2A
Thanx for your help, and this tool.

I am working with large 3hr+ encrypted content with multiple bitrates, and attempting to DASH-ify as follows:
```
"C:\Program Files\GPAC\mp4box.exe" -dash 4000 -profile onDemand -frag 2000 -rap -frag-rap -sample-groups-traf -profile onDemand -out "D:\GCTMP\ism\dash-output\V43000_1435191167327.mpd" "D:\GCTMP\ism\V43000_3500000-encrypted.mp4"#video:id=video_1_1 "D:\GCTMP\ism\V43000_2000000-encrypted.

```
The largest bitrate file `D:\GCTMP\ism\V43000_3500000-encrypted.mp4` causes mp4box to produce the following output:

The dash command completes, and exits cleanly - but during the process truncates the largest bitrate file significantly:

2 Dir(s) 432 615 669 760 bytes free
```
Note that V43000_3500000-encrypted_track1_dashinit.mp4 is 4,295,619,588 bytes (bordering on a u32 max int value). I was expecting this to be around the same size of the encrypted mp4:
```

2015-06-26 11:04 5 322 667 231 V43000_3500000.mp4
```
It looks like this is intentional, if I look at:
https://github.com/gpac/gpac/blob/master/src/isomedia/box_code_drm.c
I can see there is a check to see if the current position within the bitstream is > 32bits:
```
GF_Err store_senc_info(GF_SampleEncryptionBox *ptr, GF_BitStream *bs)
{
GF_Err e;
u64 pos;
if (!ptr->cenc_saio) return GF_OK;
pos = gf_bs_get_position(bs);
if (pos>0xFFFFFFFFULL) {
GF_LOG(GF_LOG_ERROR, GF_LOG_CONTAINER, ("[iso file] \"senc\" offset larger than 32-bits , cannot store.\n"));
return GF_NOT_SUPPORTED;
}
e = gf_bs_seek(bs, ptr->cenc_saio->offset_first_offset_field);
if (e) return e;
if (ptr->traf) {
gf_bs_write_u32(bs, (u32) ( pos - ptr->traf->moof_start_in_bs) );
} else {
gf_bs_write_u32(bs, (u32) pos);
}
return gf_bs_seek(bs, pos);
}
```
The pos counter is a u64, and it appears there is a u64 version of gf_bs_write in src/utils/bitstream.c. Is it possible to selectively use this implementation here?
The encrypted files are available on a public http server for testing with:
```

Hi,
I'm testing segment-timeline but I found some segment names are incorrect. Here is the result segment template;
``` xml
<SegmentTemplate initialization="$RepresentationID$/init.mp4" media="$RepresentationID$/$Time$.m4s" startNumber="1" timescale="1000">
<SegmentTimeline>
<S d="4992" r="3" t="0"/>
<S d="4993"/>
<S d="4992" r="1"/>
<S d="4993"/>
<S d="4992"/>
<S d="4842"/>
</SegmentTimeline>
</SegmentTemplate>
```
And two sets of segments are created;
RepresentationID=1: init.mp4 0.m4s 4992.m4s 9984.m4s 14976.m4s 19968.m4s 24961.m4s 29953.m4s 34945.m4s 39938.m4s 44930.m4s
RepresentationID=2: init.mp4 0.m4s 4992.m4s 9984.m4s 14976.m4s 19968.m4s 24960.m4s 29952.m4s 34944.m4s 39936.m4s 44928.m4s
The segment names for RepresentationID=2 are incorrect. If you follow the segment timeline, the 6th segment should be 24961 not 24960. Following names are also incorrect.
I noticed dash_segmenter.c will calculate drift and adjust period_duration by adding tick. But following files do not follow segment timeline.

This is a feature request - I have a video device that outputs mpeg4 / h264 encoded stream to named pipe. I would like to use MP4Box to create DASH-mpd file for this named pipe input stream. Application is used on Windows OS.
In case this already exists, please point me to the documentation.

When encoding mpeg dash streams with multiple representations we encounter a wrong index for the first representation. The sampleDescriptionIndex in the Track Fragment Header box of the first representation is 0. For the next representations it continues with 2, 3 and so on ...
Looking into MPEG4 part 12 indices usually start with 1. Unfortunately for this box it is not defined, but I found another place in that spec where a sampleDescriptionIndex runs from 1 to number of samples.
The init segment for the video contains three avc1 boxes which is fine (-bs-switching and profile)
The indices I found are 0, 2, and 3
Here is the call to mp4box
MP4Box - GPAC version 0.5.2-DEV-rev499-ga222f5f-master

Can I attach some samples to this issue? This is my first bug report here, so some guidance how I can support fixing the issue is much appreciated.

Currently, the chapters only appear properly when the file is completely downloaded. When progressive streaming, the chapters only sometimes appear if the file is paused immediately, or if left to play it sometimes works.

Hi,
I pull the latest code in order to try #158 but met segmentation fault. I paste the command I used (same as #158) here FYI.
$MP4Box -dash 5005 -dash-profile dashavc264:live -bs-switching no -url-template -segment-timeline -segment-name 'seg_$Bandwidth$_$ime$' -out ooxx.mpd audio.mp4 video.mp4

Hi !
I'm trying to use Gpac on windows with some modifications on the openhevc decoder.
Since there are problems compiling openHevc on windows, I used Linux (ubuntu 14.04 64bits) to compile openHevc with my modifications. Since the compilation generates a .so library I used the scripts from "https://github.com/OpenHEVC/HevcCompilationScripts" to cross-compile and generate libOpenHevcWrapper.dll.
When I moved to windows, I installed win64 Gpac nightly build and I susbstituted the libOpenHevcWrapper.dll by the cross compiled one and I got the following error:
"the program cannot start because libwinpthread-1.dll is missing from your computer. Try reinstalling the program to fix the problem"
1- I my approach to use cross compilation correct? If yes how can I avoid problems related to pthread?
2- If the approach is wrong what can you advice me what to do to have Gpac running with the new openHevc code?
Thank you !

Platform: OS X
Version: 10.8 - 10.10.4
Tested against 0.5.2 & current Git master build.
It seems to be impossible to opt-out of linking `gpac` to `x11` when X11 is available on the machine, even when you tell `configure` you don't want the X11 elements.
```
./configure --prefix=/Users/Dominyk/Downloads/gpac-0.5.2/TESTING --disable-x11-shm --disable-x11-xv --X11-path=no
```
`config.mak` sets:
```
CONFIG_X11=yes
X11_LIB_PATH=no/lib
X11_INC_PATH=no/include
```
And then `make` blows up:
```
In file included from x11_out.c:26:
./x11_out.h:38:10: fatal error: 'X11/Xlib.h' file not found
#include <X11/Xlib.h>
^
1 error generated.
make[2]: *** [x11_out.o] Error 1
make[1]: *** [plugs] Error 2
make: *** [all] Error 2
```
Not setting any `--X11-path` doesn't work either. `config.mak` ends up with:
```
CONFIG_X11=yes
X11_LIB_PATH=/usr/X11R6/lib
X11_INC_PATH=/usr/X11R6/include
```
And then configures in `x11` availability even though I specifically requested it doesn't:
```
~> otool -L gpac-0.5.2/TESTING/lib/gpac/* | grep x11
gpac-0.5.2/TESTING/lib/gpac/gm_x11_out.dylib:
../../bin/gcc/gm_x11_out.dylib (compatibility version 0.0.0, current version 0.0.0)
```

Hello,
Here is a problem I've encountered while testing EBU-TT-D content: if a document contains several captions in different regions, but active at the same time, the import will give me this result:
Document:
```

MP4Box import:
```
TTML: timing overlapping not supported: "begin" is 14040 , last "end" was 17028. Abort.
Unsupported TTML file - only EBU-TTD is supported (root shall be "tt", got tt)
Importing as generic TTML
Saving elephantsdream_25fps-multipleRegions.mp4: 0.500 secs Interleaving
```
MP4Box does not support timing overlapping, however EBU-TT-D needs the support of several active regions at the same time and my guess is that probably other subtitle XML based will need that too?
Thanks

Hello,
Here is a problem I've encountered while testing EBU-TT-D content: if a document contains one or multiple div tags, after the dashing of video, audio and the ttml content (mp4), the div tags will be erased and not appear at reception on the dash client.
Here is how to reproduce and the results:

Received only once.
etc. etc.
You can note the disappearance of the div tag, which is obviously essential to render the captions as it defines the region.

Now, I'm perfectly willing to say this is "pilot error" but so far I don't think so.
I am doing some remuxing of mp4 files using mp4box and overall it works great except for chapters.
I initially imported chapters in this format:
```
00:00:00.000 Chapter 1
00:06:30.307 Chapter 2
00:13:59.589 Chapter 3
00:21:06.515 Chapter 4
```
The command:
```
mp4box -chap chapters_file.txt
```
... imports it fine.
However, when it's exported as raw, it produces a binary file that appears to just have the chapter labels in it. mp4box doesn't seem to understand this file at all for import.
If I use dump-chap I get two files, the same binary file above and a XML format file containing the timecodes but not the labels for the chapters. Again, I haven't been able to then reimport this using -add or -chap.
It would be nice if it could just export the chapters in a text file with the "HH:MM:SS.MS LABEL" format or at least some single file with all the information that it could reimport ok.

Hi,
I'm considering this might be a potential MP4Box bug. Here is the command I used to generate MPD with segment-timeline.
MP4Box -dash 5005 -dash-profile dashavc264:live -bs-switching no -url-template -segment-timeline
-segment-name 'seg_$Bandwidth$_$Time$' -out ooxx.mpd audio.mp4 video.mp4
The generated MPD and media segments could be played with dash.js, but not Silverlight. After several trial & error, I found SegmentTemplate@timescale is not expected by Silverlight. From the segment request pattern, I found Silverlight expected timescale of 'sidx' box. Actually, there is a sentence in 5.3.9.6.1 ISO/IEC 23009-1, it says
— the value of @timescale shall be identical to the value of the timescale field in the first ‘sidx’ box
In my case, the timescale value of 'sidx' box of the first (audio) media segment is 48000. Here is the partial dump via MP4Box -info -diso seg_33624_0.m4s;
``` xml
<!--MP4Box dump trace-->
<IsoMediaFile Name="seg_33624_0.m4s">
<SegmentTypeBox MajorBrand="msdh" MinorVersion="0">
<BoxInfo Size="24" Type="styp"/>
<BrandEntry AlternateBrand="msdh"/>
<BrandEntry AlternateBrand="msix"/>
</SegmentTypeBox>
<SegmentIndexBox reference_ID="1" timescale="48000" earliest_presentation_time="0" first_offset="0">
<BoxInfo Size="44" Type="sidx"/>
```
And the segment-timeline of audio representation is listed below. The timescale is the default value, 1000, of MP4Box.
``` xml
<AdaptationSet segmentAlignment="true" lang="und">
<SegmentTemplate timescale="1000" media="seg_$Bandwidth$_$Time$.m4s" startNumber="1" initialization="seg_$Bandwidth$_.mp4">
<SegmentTimeline>
<S t="0" d="4992" r="8"/>
<S d="4794"/>
</SegmentTimeline>
</SegmentTemplate>
<Representation id="1" mimeType="audio/mp4" codecs="mp4a.40.2" audioSamplingRate="48000" startWithSAP="1" bandwidth="33624">
<AudioChannelConfiguration schemeIdUri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="2"/>
</Representation>
</AdaptationSet>
```
Video adaptationset has the same issue too.
Please kindly let me if the issue could be addressed with correct options. Let me know if my interpretation is incorrect. Welcome for the discussion.
Thanks,
Wesley

Hi,
I follow the [link](http://www.gpac-licensing.com/2014/08/21/ibc-2014-dash-avc264-support-in-gpac/) to generate MPD with SegmentTimeline support. Below is my command;
$MP4Box -dash 10000 -rap -dash-profile dashavc264:live -bs-switching no -url-template -segment-timeline -segment-name seg_$Bandwdth$_$Time$ -out ooxx.mpd audio.mp4 video.mp4
The command generated the file as below;
$ls
audio.mp4 seg_ls$1.m4s seg_ls$3.m4s seg_ls$5.m4s seg_ls$init.mp4
ooxx.mpd seg_ls$2.m4s seg_ls$4.m4s seg_ls$6.m4s video.mp4
The naming is much different from the segment-name I specified; I don't know where 'ls' come from.
And here is the MPD;

I've run into a bug in 'MP4Box -crypt' which I will get 2 identical IVs in a row in the 'senc' box. InternetExplorer 11 will not play the file when this happens. The changed that introduced the bug was a36e8d85. If I checkout right before this change the problem goes away and my encrypted files will play in IE11.
I don't understand the code completely, but the CENC refactor in the change referenced above now looks at the first byte in the IV and only increments the counter if this byte is not 0. I understand that this first byte is not actually a part of the IV (since the IV buffer is 17 bytes instead of 16), but I don't quite understand what it is used for. In my test case, this first byte ends up being 0 on the 8th sample and the IV counter is not incremented.
To reproduce, [I have shared the media file and the crypt file here](https://www.dropbox.com/sh/nskuvzticp31su7/AAATNaeVUqGoTaiq9KhVMt0ca?dl=0).
```
MP4Box -crypt pr_video.xml -out encrypted.mp4 video_512x288_h264-360k.mp4

Double-click to full screen. When typing on the 'escape' key, the full screen is black with the image at tits original resolution on the bottom left corner, no window. Alt-tab was stuck, I had to do ctrl+alt+sup on Windows to get control again.
Thanks for your help :)

I've noticed that when using "-splitz" the value for the output filename ("-out") parameter is ignored. Using "-splitx" does seem to work properly. This seems to be the case even using versions as far back as 0.5.0. Below is a sample using the nightly build (windows under cygwin - 0.5.2-DEV-rev388-gd9aea85-master)
$ mp4box -splitx 60:120 BigBuckBunny_320x180.mp4 -out bb-splitx.mp4

Hi,
When removing a sample, I sometimes (depending on the content) get a raised assert at:
```
//always called before removing the sample from SampleSize
GF_Err stbl_RemoveCTS(GF_SampleTableBox *stbl, u32 sampleNumber)
{
GF_CompositionOffsetBox *ctts = stbl->CompositionOffset;
assert(ctts->unpack_mode); //ASSERT
[...]
```
Content to trigger: http://download.tsi.telecom-paristech.fr/gpac/DASH_CONFORMANCE/TelecomParisTech/sources/counter_video_360.mp4
Callstack:
```
> libgpac.dll!stbl_RemoveCTS(GF_SampleTableBox * stbl, unsigned int sampleNumber) Line 934 C
libgpac.dll!gf_isom_remove_sample(__tag_isom * movie, unsigned int trackNumber, unsigned int sampleNumber) Line 1040 + 0x1a bytes C
__caller__
```
The removal code:
```
{
u32 di;
GF_ISOSample *s = gf_isom_get_sample(in, trackNumber, i, &di);
e = gf_isom_remove_sample(in, trackNumber, i); //CRASH
gf_isom_sample_del(&s);
assert(e == GF_OK);
}
```
Ideas?

Hi,
I'm trying to use segment timeline instead but MP4Box stopped. Below is the command I used to create MPD; (use audio only for simplicity).
MP4Box -dash 5005 -rap -segment-name seg_$Bandwidth$_$Time$ -url-template -segment-timeline -bs-switching no audio_p0.mp4
And the output of the command is
DASH-ing file: 5.00s segments 5.00s fragments single sidx per segment
Spliting segments at GOP boundaries
DASHing file audio_p0.mp4
[DASH]: Drift between minCTS of segment and MPD start time is 4.18294e+11 s
Assertion failed: (diff>0), function gf_media_isom_segment_file, file media_tools/dash_segmenter.c, line 1711.
Abort trap: 6
Some notes here;
- No problem if segment template is used
- No problem for video part
Any suggestion to investigate the issue further?

This issue was initially raised on SourceForge (https://sourceforge.net/p/gpac/discussion/287547/thread/ae1ad5e4/?limit=25#8d7b).
According to ISO/IEC 14496-15:2014 and Cor1, CRA samples are sync samples.
|
MP4Box should mark HEVC CRA as sync samples

Download the latest code source, and compile it.
Change Osmo4.java as follows:
```
/**
* @see com.gpac.Osmo4.GpacCallback#onGPACReady()
*/
@Override
public void onGPACReady() {
startupProgress.dismiss();
Log.i(LOG_OSMO_TAG, "GPAC is ready"); //$NON-NLS-1$
String url = "http://www.digitalprimates.net/dash/streams/mp4-live-template/mp4-live-mpd-AV-BS.mpd";
openURLasync(url);
}
```
...
```
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Handle the back button
if (keyCode == KeyEvent.KEYCODE_BACK) {
// Stop the activity
if ( mGLView != null )
mGLView.disconnect();
Osmo4.this.finish();
return true;
} else {
return super.onKeyDown(keyCode, event);
}
}
```
Install "Osmo4_android" and reopen it quickly. Repeat several times, I got "Unfortunately, Osmo4 has stopped".

I don't know if this is a real issue, but the duration computed in SetTrackDuration() states:
```
//if we have an edit list, the duration is the sum of all the editList
//entries' duration (always expressed in MovieTimeScale)
```
which seems contradictory. I think gf_isom_set_last_sample_duration() should update the edit lists but I don't know how. Ideas?

Hello gpac team,
we compile mp4box from you with that script:
https://github.com/jb-alvarado/media-autobuild_suite
In the past it was working normal, but now we can not use `-hint` in the static compilation anymore. When we compile it with a shared lib, `-hint` works normal.
Do you have any idea?

Hi there,
When I add chapters to an M4A using MP4Box, the chapters do not display within iTunes. This behaviour happens when the file is progressively downloading / pseudo streaming and has not already been downloaded. I'm observing the behaviour on podcasts.
If playback is paused immediately, the chapters menu does normally appear. Otherwise, it may take a long time to appear or might not appear at all.
Here is a comparison of the output from the AtomicParsley -T command, for a file chaptered with MP4Box, versus one made with Garageband 6.0.5:
