Hi,
I've been experiencing crashes using the mp42ts tool. Some debugging shows that the write in l. 1406 of src/isomedia/stbl_write.c can corrupt the heap:
stbl->SampleSize->sizes[stbl->SampleSize->sampleCount] = size;
The problem is that there are scenarios in which the stbl->SampleSize->sizes buffer is allocated to just stbl->SampleSize->sampleCount elements by the preceding gf_realloc() in l. 1396. E.g. in my case I had stbl->SampleSize->sampleCount=100 while stbl->SampleSize->alloc_size was still 0. This causes the ALLOC_INC() macro to set stbl->SampleSize->alloc_size also to 100 and then to alloc just 100 elements for the buffer. In result, l.1406 then writes behind the end of the buffer.
I've inlined a tiny patch below which fixed the issue for me. Obviously, there are many other ways to o how to fix it. Whichever way you do it, the stbl->SampleSize->sizes buffer just must be at least sized to stbl->SampleSize->sampleCount+1 elements after the realloc no matter what - and that's currently not the case...
Proposed patch:
```
diff --git a/src/isomedia/stbl_write.c b/src/isomedia/stbl_write.c

hi all,
i am trying to use mp4box for live streaming dash content under window 7 64bit platform,
i used a 46 second long pre-recorded V/A mp4 as my source file,
first i used mp4box to divide it into 2 mp4 containing only 1 track each,
then i used the video only file for the test,
my command is:
mp4box -dash-live 6000 -mpd-refresh 12 -out test.mpd src.mp4
then i use mp4client:
mp4client test.mpd
i got log messge:
> Opening URL test.mpd
> Service Connected
> [GLSL] Failed to compile vertex shader: ERROR: 0:17: '' : syntax error: incorrect preprocessor directive
>
> [Compositor] Failed to compile vertex shader
> [SyncLayer] ES1 (test.mpd): Something really wrong, decoding buffer exceeded (1271327 ms vs 3000 max) - trashing buffers
i could see player GUI popped up, but nothing actually displayed...
any help or advise would be appreciated!

Hello,
I use DashCast on ubuntu 14.04 for transcoding a live stream in multiple qualities.
However, I encounter such problem "Video scaler: error while resizing picture."
Here is my command:
DashCast -vf video4linux2 -vfr 24 -v4l2f yuyv422 -v /dev/video0 -conf dashcast.conf -live
Here is my dashcast.conf:
[v1]
type=video
bitrate=800000
width=1280
height=720
crop_x=0
low_delay=yes
crop_y=0
codec=libx264
[v2]
type=video
bitrate=400000
width=640
height=360
crop_x=0
low_delay=yes
crop_y=0
codec=libx264
Who can give me some guidelines?
Thanks.
Linda.

Hi. This is most likely a stupid question, but where can I install the plugin that allows Osmo4 to be integrated into the browser? I've been currently following the instructions found here: https://gpac.wp.mines-telecom.fr/player/browser-integration/
I've installed the latest dev build for GPAC on Windows, but when I navigate to my webpage on Mozilla Firefox, I get an error that says "A plugin is needed to display this content"

from https://sourceforge.net/p/gpac/discussion/287547/thread/904ae7e1/
GPAC looks for modules in the following directories: /usr/lib/gpac, /usr/local/lib/gpac, /opt/lib/gpac, /opt/local/lib/gpac. Do you have any of them on your disk? Otherwise you should find where the module directory is with 'locate' and add it to your LD_LIBRARY_PATH.
suggest do: sudo ln -s /usr/lib/i386-linux-gnu/gpac /opt/lib/gpac
but maybe it is better add /usr/lib64/gpac/ to the search PATH
Thanks

Is there a way to get a log for MP4Client DASH metrics/stats? I want a similar file that results from "MP4Client -rti" but with the estimated bandwidth, the representation bitrate, the buffer occupancy (in bytes and in seconds), the representation level, etc. along with the cpu and memory. I want to make by myself a graphic like the "stats window" in the Osmo4 GUI using this information.
Thanks in advance.

Hello,
I want to transcode a live/non-live stream in multiple qualities (eg. bitrate and resolution) by DashCast in windows 64bit.
The command is:
D:\wamp\www>DashCast -vf dshow -vres 1280x720 -vfr 24 -v video="screen-capture-recorder" -live -npt
s -time-shift -1 -seg-dur 2000
The config file is:
[v1]
type=video
width=1280
height=720
bitrate=800000
[v2]
type=video
width=640
height=360
bitrate=400000
[a1]
type=audio
bitrate=128000
[a2]
type=audio
bitrate=256000
But when I run this command, I will recieved this error:

...
What's the problem with this?
Who can tell me a correct way to transcode a live/non-live stream in multiple qualities (eg. bitrate and resolution) by DashCast in windows 64bit.
Thanks,
James.

When encoding "OpenGOP" using x264 we will get one IDR at the beginning and a number of I frames marked with a recovery point SEI message. When muxing using mp4box these recovery point samples will not be put into the "rap " group but instead be marked via the "roll" group with a "roll_distance" of "0".
1.) Why "roll" instead of "rap "?
2.) Why "roll_distance" of "0"? According to ISO/IEC 14496-12:2015 chapter 10.1.1.3 "The value zero must not be used".

I am using Ubuntu 14.04 LTS. I downloaded the latest GPAC source and tried to build. However, the dashcast source is creating error when I execute make. It shows the following error:
make[2]: **\* [video_encoder.o] Error 1
make[2]: Leaving directory `/home/khalid/gpac/applications/dashcast'
make[1]: *** [apps] Error 2
make[1]: Leaving directory`/home/khalid/gpac/applications'
make: **\* [all] Error 2
How should I fix this to get the latest GPAC that has all apps running fine, most importantly dashcast?
Thank you.

Test stream: http://media.blacktrash.org/fp/test/night1.mpd
The dash.js (I can't get Osmo to work on OS X, only white screen) sample player tries to load http://media.blacktrash.org/fp/test/night1/dash/1-6.m4s as last audio segment which does not exist.
Counter example without template: http://stream.flowplayer.org/night1.mpd works without problems.
Segment template for the audio representation is:
``` xml
<SegmentTemplate timescale="44100" media="$RepresentationID$-$Number$.m4s" startNumber="1" duration="88064" initialization="$RepresentationID$-.mp4"/>
```
Maybe because 88064 / 44100 = 1.99691609977324263038 is minutely less than 2 (2 second segments)?
See also: https://github.com/Dash-Industry-Forum/dash.js/issues/950
Maybe related or duplicate of #223.

Hello! I encountered a problem, when extracting audio tracks from a *.mp4 container, that looks like a bug. I have an *.mp4 file that contains multiple audio tracks. The audio tracks are encoded using the ALAC codec. I want to extract those into seperate audio files using mp4box.
What I've tryed so far for extracting a track is this:
```
mp4box -single 1 "inputfile.mp4" -out "outputfile.m4a"
```
What happens is, it works as that a `outputfile.m4a` is created, but something with the header/codec/file info seems to be malformated. I can open and play the file in VLC, but it fails to open with Windows Media Player/Windows Media Foundation (which I need). So either I am doing something wrong during the extraction or mp4box puts the file in a weird format.
The output of `mp4box -info -v "outputfile.mp4"` looks like this:
```

```
I also tryed extracting the audio tracks using the `-raw` flag like this:
```
mp4box -raw 1 "inputfile.mp4"
```
It creates a `inputfile.mp4_track1.alac` file, which I can't open in any player (not even VLC). Looking at it in a HEX editor it looks like the raw data segment (which makes sense I guess), but I can't get mp4box to put it back into a .m4a which I can play.
Here is a small python script to reproduce the above error:
``` python
import os
import subprocess

```
Here is a zip file containing the `TechTalk_CC_music.m4a` track that I used for testing and in the example: [Mp4Box Test.zip](https://github.com/gpac/gpac/files/68442/Mp4Box.Test.zip)
So I guess the question is am I doing anything wrong? Am I maybe missing some flag while extracting? Or is mp4box simply producing wrong results? I hope somebody can point me in the right direction. Thanks in advance!

Since (around) GPAC 0.5.1 mp4box sets this value which is reported in -info, usually:
Chroma format 1 - Luma bit depth 8 - chroma bit depth 8
Older builds didn't do that.
If I remux that old mp4's with newer mp4box, -info flush this:
Chroma format 0 - Luma bit depth 8 - chroma bit depth 8
I recently joined some files and the first part hadn't set chroma value, so final file has chroma format from 1st chunk - 0. I can remux whole movie, that will change chroma format to 1, but should I bother with this... what this value actually causes?
...and I've noticed that after removing audio track, IOD root has no Audio PL updated (old value stored)
|
What is Chroma format ?

I can't tell from the limited documentation how to do this. It is clearly possible in the command line version: MP4Box -raw 2 file.mp4
What is the equivalent in the JavaScript version?
Thanks.

Hello!
First of all: I am new to this subject, pls be patient :)
I want to use mp4box inside cut assistant. cut assistant works fine with AVI-files so far. For mp4-files, I had to install ffdshow and "Haali Media Splitter" as well as mp4box. The path mp4box is set in cut asistant. So, when cutting a video, everything seems to work well first. At a time, processing breaks an a box apears "mp4box.exe funktioniert nicht mehr" (=mp4box does not work anymore) --> the programm crashed.
Can anybody help me?
Thank you says urmel
The log is:

Hi there, Back to Gpac after playing around with ffmpeg.
I have managed to transcode the live stream that is coming from Http input as .ts ( Enigma 2 Dreambox )using ffmpeg with no problem, but tried to play around with Dashcast and I am just ending up with errors , tried so many commands that I found them on Gpac website but to no lack. Here is the command I used for transcoding live ts to mpd file.
DashCast -av http://puplic-ip.ts -vfr 30 -vres 1280x720 -seg-dur 1000 -frag-dur 200 -conf /usr/local/nginx/html/config/testconf.conf -live -out /usr/local/nginx/html/dashed -mpd livetest.mpd
And I get this erros

puplic-ip is replaced with my real puplic-ip ,so file works fine with mp4client/vlc before transcoding .
here is the ffmpeg that works with no issue.

. ffmpeg works fine with the above code, so I am amusing all lib are fine but just cant figure it out.

I'd like some explanation of how accurate the bitrate of transport streams created by MP42TS is.
For example, I multiplexed one audio and one video in the same service, specifying -rate 8000.
The command line reported:
> Done muxing - 300 sec - average rate 8009 kbps 1597738 packets written
This suggests that the actual bitrate is 8,009,000 bps, and that it may not be constant. However, if I open the resulting stream in some other tools, they all report the bitrate as 8,000,000 bps. This includes DVB Analyser, DekTec StreamXpress, Tektronix Multiplexer and Tektronix TS Compliance Analyser.
It's important to us that the bitrate of the transport stream is accurate and constant.
First of all, please confirm whether my assumption is correct: that specifying "-rate 1" indicates a requested bitrate of 1000 bps, as opposed to 1024 bps.
Secondly, can you comment on the above conflicting diagnostics?

Hi,
had to post my question here, couldn't found any other contact addresses.
I'm writting Linux gui for MP4Box. Thinking of calling it MP4Bg or MP4BG but am afraid of eventual copyright issues because of "MP4" in the name.
Of course, GPAC team uses it, but that is different.
Please advise and after that this topic can be erased.
Thanks in advance.

This works great with dash.js 1.5.1 but for one details:
codecs="avc3.42c01e" is causing Internet Explorer 11 to not recognize the stream (black screen). If I manually change to codecs="avc1.42c01e" in the manifest then it works as expected.
Question:
Is avc3.42c01e a standard codec notation? I was under the impression that avc1.xxxx was.
How can I make it so that codecs information are reported with avc1.xxxx instead of avc3.xxxx in manifest.mpd?
Thanks
Arnaud

Hi,
I'm trying to compile GPAC on a Raspberry Pi 2 (model B) with the aim of playing DASH content using MP4Client.
Has this been done before?
Is it even possible? I mean, I have managed to compile GPAC (with disable-vrml because configure cannot find the Javascript library), but when I run MP4Client it doesn't display anything. I tried configure with disable-3d (because MP4Client complained about not being able to open a GL display), but it doesn't seem to help. Since the Raspberry Pi has a somewhat non-standard architecture (Broadcom SoC with integrated GPU), maybe there is something specific that I need to set?
I am compiling directly on the board, so I don't need to set up a cross-compiling environment, and also the board is fast enough so compilation is reasonably fast.
Thank you,
Matthieu

Hello there,
I did set up the code in my Linux Ubuntu platform, and I typed the command of Live streaming from my webcam, as the following command "DashCast -vf video4linux2 -vfr 30 -vres 650x480 -v /device/video0 -live".
I got some of the output coming in changeable files in the "Output" folder, which is in the directory of GPAC.
However, I want to visualise these streams, by using the MP4Client for example, as it is stated in your documentation. But unfortunately I don't know how to manage the viewing of this live stream by the use of the MP4Client.
I am really intersted in making some contribution in this field, and I am looking forward to getting the answer of how to visualise the output files.
All regards,
|

If I extract VOBSUB .idx and .sub files from an MP4 file, the resulting .idx file is bad. This used to work in previous versions of mp4box. The problem appears to be the offsets are written to the file as a decimal string instead of in hex like it used to. This is an issue in the latest overnight build and goes back at least as far as gpac-0.5.2-DEV-rev724
For example:
Current output:
langidx: 0
id: en, index: 0
timestamp: 00:01:11:371, filepos: 000000000
timestamp: 00:01:28:621, filepos: 000004096
timestamp: 00:01:36:496, filepos: 000006144
timestamp: 00:01:44:104, filepos: 000010240
Previous (correct) output:
langidx: 0
id: en, index: 0
timestamp: 00:01:11:371, filepos: 000000000
timestamp: 00:01:28:621, filepos: 000001000
timestamp: 00:01:36:496, filepos: 000001800
timestamp: 00:01:44:104, filepos: 000002800

I'm streaming from webcam using the command `-vf video4linux2 -vres 320x240 -vfr 30 -v4l2f mjpeg -v /dev/video0 -live -out /opt/lampp/htdocs/dash -conf dashcast.conf`
When trying to play the stream using mp4client it displays only one frame and shows the following error. The playback is fine when I'm using libx264.

I'm trying to stream libx265 encoded video using the following command.
```
DashCast -vf video4linux2 -vres 320x240 -vfr 25 -v4l2f mjpeg -v /dev/video0 -live -out /opt/lampp/htdocs/dash -conf dashcast.conf
```
I can only play the first frame of the video using MP4Client. DashCast outputs a lot of `[dashcast] Live system dropped a video frame` and `[video_encoder] Rep v1 UTC diff at segment close: 9960 is lower than cumulated segment duration 11000 (diff -1040) - frame rate is probably not correct or frames were lost!` DashCast with libx265 takes too much CPU compared to that of libx264 (Around 300% for libx265 and 100% for libx264).
How can I improve the performance and stream the video correctly?
This is what I get in the client side.

I'm a newbie in streaming with ffmpeg and Mp4box. I tried to find solution from some website:
http://sourceforge.net/p/gpac/discussion/287547/thread/bb9a9893/?limit=50
http://stackoverflow.com/questions/33773093/convert-video-by-ffmpeg-not-working-in-chrome
http://blog.streamroot.io/encode-multi-bitrate-videos-mpeg-dash-mse-based-media-players/
but I couldn't.
What did i do wrong? Please help me. Thanks alot
My input file is downloaded from youtube (.mp4 file).
I used command to get only video with format h264 (without sound) :
```
$ ffmpeg -y -i "E:\SharingVideo\src\main\webapp\resources\video\input\input.mp4" -an -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:720" "E:\SharingVideo\src\main\webapp\resources\video\input\input_an.mp4"
```
Cmd result:

What could be the problem? Changing codec to libx264 in the conf file works fine.

I have been looking to fix or investigate this issue for the last few days, but to no lack.
Anyone know why I am getting this error? as the installed is done with no error .I have installed it using this tutorial ( https://gpac.wp.mines-telecom.fr/dashcast/ )
and also downloaded the ISO latest build ( https://gpac.wp.mines-telecom.fr/downloads/gpac-nightly-builds/). both didn't work.
I am and using Ubuntu server Ubuntu Server 14.04.3 LTS and its 64bit.
I am totally new to Linux so please a noob explanation will be helpful.
Thanks everyone for the help.

Hi,
I have noticed that videos, animations and user interaction in a BIFS scene running on an Android device are very (very) slow compared to how it used to be a while ago. For example in a more complex scene the TouchSensor is not even triggered most of the time (e.g. clicking a button).
Here's a simple example from regression tests where some interpolators are used with Layer3D: _bifs-3D-positioning-layer3D-views.bt_.
I don't know how can I see the fps on the Android device but there are no more than 5 fps. Could you investigate this issue or at least give me some hints on how should I proceed to fix this?
Thank you!

According to ISO/IEC 14496 Part10, the definition of 'dref' tells us that the media data can be placed in another file,so can I split a normal mp4 file into 2 mp4 file,one is metadata.mp4 and the other is mediadata.mp4?
|
Is there a way to split a mp4 into 2 mp4, one is metadata.mp4 and another is mediadata.mp4

Hello,
I was building MP4Box on Centos 7 Minimal Installation today and ran into errors when compiling. I have followed the same protocol a few times in the past, most recently about 36 hours ago, so I am stumped as to why I am running into these issues.
I followed the instruction on this page: https://gpac.wp.mines-telecom.fr/ under the "Build MP4Box with Make" section. I have bolded the commands and pasted the outputs below each command for reference.
Any help would be greatly appreciated!
Thanks!,
David

Hi,
When I am dashing a AAC-LC audio file with following command:
`MP4Box -rap -profile live -dash 2000 -out template.mpd test.m4a`
In the template.mpd file, the `par` attribute appears in the `AdpatationSet` element:
`<AdaptationSet segmentAlignment="true" par="1:1" lang="und">`
This issue only occurs when I updated from 0.5.2-DEV-rev552-g5a1b427-master to 0.5.2-DEV-rev1006-g9f09b13-HEAD
|

Hello!
I am trying to add a subtitle to my mpd file, but mp4box tells me not supported for dashing. I understand that and if I remove the last line it works fine (without the subtitle ofcourse)
```
MP4Box -dash 4000 -frag-rap -profile dashavc264:live -bs-switching no ^
-no-frags-default -segment-name $RepresentationID$/segment_ ^
-noprog -out D:\o\movie\play.mpd ^
D:\o\video_1920x1080_3500.mp4:id=video_1920x1080_3500 ^
D:\o\sub_0.srt:id=sub_fr:fmt=VTT
```
So how can I make the manifest to work with dashed files and a whole subtitle file?
Example I would like it to be added like this:
```
<AdaptationSet id="21" mimeType="text/vtt" lang="fr">
<Representation id="21">
<BaseURL>subs/s-pt-fr.vtt</BaseURL>
</Representation>
</AdaptationSet>
```
I hope I made myself somewhat clear; thanks in advance :)

Hello,
I want to know whether or not the generation rate of MPD file is connected with the -seg-dur.
What's more, how can I control the generation rate of the MPD file.
Thanks,

Commit https://github.com/gpac/gpac/commit/a3363ba3edbd8346f4035f7e407ab27a39cedf4d introduces some new "cp" invocations to the Makefile with the "--no-preserve" command-line flag.
This flag is specific to GNU cp, so its introduction causes "make install" to fail on MacOS X with the error "cp: illegal option -- -".

I'm trying to use MP4Box to generate an mpeg-dash (html5) video using widevine drm+encryption however when I create the mpd the video is not getting encrypted. Here's my test `crypt.xml`:

Here is the command I run to create an mpd:
```
$ MP4Box -crypt crypt.xml -dash 10 -profile onDemand -out output/output.mpd input/video.mp4 input/audio.m4a

The generated audio and video files are playable in VLC and I get no diagnostics output from MP4Box indicating anything has gone wrong.

Hello,
I am trying to create a stable live dash stream with DashCast. The goal is to play it in dash.js but at the moment I cannot play it with MP4Client neither.
I create a udp stream with ffmpeg
`ffmpeg -re -i test.ts -c copy -f mpegts udp://127.0.0.1:1234?pkt_size=1316`
Then with DashCast (GPAC version 0.5.2-DEV-rev976-gbad2125-master) on Ubuntu 14.
`DashCast -av "udp://127.0.0.1:1234?fifo_size=100000" -live -out /var/www/dash -seg-dur 4000 -mpd-refresh 4000 -conf dashcast.conf`
dashcast.conf is
```

bitrate=400000

```
Then playing my DASH stream on another computer (Windows 10)
`MP4Client http://192.168.1.28/dash/dashcast.mpd`
Here comes trouble:

I have the same bottom line error with dash.js basically the player is looking for chunks that are never created:
http://192.168.1.28:80/dash/a1_362262017_gpac.m4s
What does exists are chunks named a1_59_gpac.m4s or v1_59_gpac.m4s but chunks like a1_362262017_gpac.m4s are never created.
Attached is the mpd.
``` xml

I am missing something I know but what?
It seems to come from the $RepresentationID$_$Number$_gpac.m4s in the mpd.
Thanks for any help you might provide.

I am using dashCast to capture from webcam:
DashCast -vf video4linux2 -v4l2f mjpeg -vfr 30 -vres 1280x720 -v /dev/video0 -af alsa -a plughw:PCH,0 -conf dashcast.conf -live -out /outdir
dashcast.mpd is getting generated but with errors. when I play with dash.js, it is searching for different segment time than available and it is showing "length not defined".
I am not getting the MP4Box right command for dash-ctx. Moreover, in my dash.mpd duration is less than timescale which is wrong I guess.
My mpd is given below:

while capturing the video with ffmpeg, when I run command MP4Box -dash 1000 -frag 1000 -rap -dash-profile live test.mp4, it is showing moov-atom not defined.
So, I tried with -movflags empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof, still it is showing error:
Thanks in advance.

I installed the last nightly build (osmo4-0.5.2-DEV-latest-master-stagefright.apk) on Android 5.1.1 and the PNG images are not being displayed. I simply start Osmo4 and open a png image. There is no error in the logs except a "Invalid qct format (611)". I also compiled the sources and generate the APK and I got the same behaviour. I have tried it on some other device and got the same issue.

Hi, I am trying to create a live stream. I am using the follow command:
MP4Box -dash 1000 -profile live video.mp4
With MP4Client the MPD works fine but when I try to use with dash.js form dash-if I am receiving this log and the video does not start.
[Log] [dash.js 1.5.1] new MediaPlayer instance has been created (dash.all.js, line 10)

Hello.
I get gpac revision-727 and tried to build version for Android from original sources.
The build command used is "./gpac_build_android -ndk=/opt/android_ndk -sdk=/opt/android_sdk -ant=/usr/bin/ant -force_rebuild". The target used by default is 18 API, however, I test it on Nexus 6, Android 5.1.1.
In the end of building process I got the error "zipalign: error while loading shared libraries: libc++.so: cannot open shared object file: No such file or directory", but the build is successful, I mean I can find /gpac/applications/osmo4_android/bin/Osmo4-release.apk file.
When I open it, I got several errors:
"Error
[Core] Cannot load module file /data/data/com.gpac.Osmo4/lib//libgm_ffmpeg_in.so, error is dlopen failed: cannot locate symbol "_ZN7android16MediaBufferGroup14acquire_bufferEPPNS_11MediaBufferE" referenced by "libavcodec.so"...
"Error
[Core] Cannot load library libgm_ffmepg_in.so"
"Error
[Terminal] Did not find any input plugin for URL /data/data/com.gpac.Osmo4/gui/extensions/bifs_tests/ (no mime type)"
Then I tried to open .mpd (DASH) file and errors:
"Error
[Codec] ODM1 ES1: Cannot find decoder for stream type MPEG-4 AVC|H264 Video"
Just in case I tried to test this apk in Genymotion.
With Nexus 4 - 4.3 - API 18 Osmo4 gives me next error just on start:
"Error
[Terminal Did not find any input plugin for URL /data/data/com.gpac.Osmo4/gui/extensions/bifs_tests/ (no mime type)"
However, when I open .mpd (DASH) file, the video works well.
With Nexus 6 - 5.1.0 - API 22 Osmo4 gives the same error as in previous case, but the video doesn't work.
How can I make it works on real Android devices? For beginning, at least on Nexus 6 with Android 5.1.0.

I do merge two 3gp files by using the following command:
MP4Box file1.3gp -cat file2.3gp -out output.3gp
I found MP4Box can't process sbgp or sgpd box. If there are sbgp and sgpd boxex in file2.3gp, MP4Box will discard those boxes when concatenating two files.
why does MP4Box not process those boxes? Is it a bug?

```
if (samp->DTS >= pck->stream->first_dts) {
.
.
} else {
GF_LOG(GF_LOG_ERROR, GF_LOG_CONTAINER, ("[MPEG-2 TS Import] negative time sample - skipping\n"));
}
```
We have found that the samp->DTS value appears to wraparound causing mp4box to needlessly drop data.
I have made a very simple patch in my own fork of gpac, https://github.com/NathanLewis/gpac that appears to fix the problem.
I have .ts input file which reproduces the data loss problem which I am happy to provide to anyone investigating this but cannot make world viewable due to copyright issues.
Thanks,
Nathan

Wish I had better Steps To Reproduce, but I'm seeing occasional .m4s files being produced that are invalid and can't be decoded by browsers. From running:
```
bin/gcc/DashCast -vf avfoundation -vres 1280x720 -v "Capture screen 0" -vfr 25 -live -no-loop

Hi, is any way to rearrange tracks ID's when importing via mp4box?
It always cloning them from original, I don't want audio on ID#1 :/
Can't dump to raw, it's vfr movie.

Hi, I tried to use the mpegts testapps form the gpac repository, but I am just receiving GF_M2TS_EVT_PES_PCR instead of GF_M2TS_EVT_PES_PCK. I tried different files and the same result for all. What is the problem? and is there any way to get this information? I would like to save in a buffer or an extern file to make test.
Thank you.

I use MP4Box on Ubuntu 12.04 64-bits to repackage TS files into MP4 files like this:
`$ MP4Box -add in.ts out.mp4`
A problem occurs with files obtained from a specific source. After being repackaged, the audio gradually goes out of sync. At the beginning audio is in sync, but after 5-10 minutes it's out of sync by one second. The problem is present when files are played in smart TV media players, but not VLC, MPlayer etc. I have tried TV's from multiple different vendors, and the problem occurs on all of them.
The problem does not occur if I use ffmpeg (0.8.17-4:0.8.17-0ubuntu0.12.04.1) from Ubuntu 12.04 repository, and repackage the files like this:
`$ ffmpeg -i in.ts -vcodec copy -acodec copy out.mp4`

When building dashcast against latest Github FFmpeg on native PPC Linux, these errors (shown below) occur.
I think they are mostly because the latest FFmpeg in `libavutil/pixfmt.h` now declares `PIX_FMT_YUV420P` as part of an enum, as `AV_PIX_FMT_YUV420P`...
Fixing this reveals another compilation error, possibly because the function `avcodec_get_frame_defaults()`isn't in FFmpeg any more. Does anyone know if these errors are trivial to fix by changing the declaration, and calling a replacement function, as per this link:

We generated transport streams using `MP42TS` and when we analysed them, we found PCR interval errors. This is where the interval between successive PCRs is greater than 40ms. This is a problem for us as we need to be DVB-compliant; the relevant requirement is test no 2.3a "PCR_repetition_error" in ETSI TR 101 290 v1.2.1.
The tool has an option `-pcr-ms` which allows you to define the max interval - but even when set to 5 ms, the generated transport stream still has intervals of more than 40ms between PCRs. In the end we found a solution that worked: if we also specify the `-single-au` option, then the PCR interval is fixed.
Is this what you would expect, or is it a bug?

We're using `MP42TS` to create transport streams with a TEMI timeline embedded in the video pid.
However, we have two additional requirements that do not appear to be supported:
1. Insert TEMI timeline into a PID carrying audio
2. Insert TEMI timeline into a PID carrying private PES data with no payload
In both cases we want the TEMI descriptors to be inserted into the adaptation field of the TS packet header, as is done with the video case.
Is this a feature that can be added?

Hi,
Using: GPAC version 0.5.2-DEV-rev91-g0930dfa-master
Please consider the content here: https://goo.gl/GsJ9Do
Both source video files in Transcoded folder are imported for hvc1. However, if I try to generate On-demand content in the DASHed folder using e.g.
MP4Box -dash 2000 -profile OnDemand -rap -frag-rap -url-template -out tos_720_HEVC_ondemand.mpd -segment-ext mp4 ../Transcoded/tos_288p_500k_H265_hvc.mp4 ../Transcoded/tos_432p_1000k_H265_hvc.mp4
2 issues:
1. The resultant codec is again hev1 and not hvc1 that we need. How can we get hvc1 as codec? If I DASH a single video using the command above, the codec is showed as hvc1; as soon as a second one is added, it goes back to hev1.
2. Also, there is a strange initialization segment generated (although MPD is not using it, understandably for On-demand content), and "bitstreamswitching" is flagged as true (even if for On-Demand I add: -bs-switching no, same behavior); I think none of this should be for On-Demand.
Thanks,
|

Hi,
We have Origin server supporting DASH HEVC 4k Streaming.
However the gpac client doesn't play the stream very well, the video is corrupted, sometimes there are lags, you can see some images overlay of strange frames while playing.
Not all content we go is able to play.
Is there anyway to fix those issues or debug them?

Hello!
I'm working on an altered version of mp4client player to play multiple streams of the same video content. A 3rd party app allows me to manually select the streams.
Everything works fine and as intended when I run it locally, but when I host the content on a server, the player automatically switches to the last stream in the list and locks on it. If I request a change, the player switches to the selected stream for a second and then switches back the previous stream:
I cannot find the reason for this. Do you know what might be causing the issue?
I have generated the content with mp4box and I have not found any issues with the MPD. I'm using node.js to generate the server.

Hi,
I am building GPAC for IOS, when I follow the rules in README.text.
I have already finished first five steps. When following step 6:
6) Compile GPAC:
execute the "gpac/build/xcode/generate_ios.sh" script.
The script checks that all files have been compiled, print an error message if needed.
Otherwise it generats a .tar.gz archive into the gpac/bin/iOS directory.
There contains error(shown in the picture):
<img width="570" alt="error" src="https://cloud.githubusercontent.com/assets/14800803/10424128/fee1dd54-70fe-11e5-9317-eedd4d2f189f.png">
Could you tell me how to solve this problem?
Best regards

I'm using MP4Box to DASH an MP4 that contains muxed audio and video. Dash.js doesn't support muxed content, so apparently the inputs must take in video and audio separately.
These are the commands I'm using:
```
ffmpeg -i video.mp4 -r 24 -g 72 -c:v libx264 -c:a libvo_aacenc -ar 44100 -ac 1 intermediate.mp4
MP4Box -dash 10000 -profile dashavc264:onDemand intermediate.mp4#video intermediate.mp4#audio
```
I'm getting the error: `[DASH]: None of the input types are supported for DASHing - nothing to do`
Using just one input `intermediate.mp4` results in a successful DASH, but due to a multiplexed representation, it'll fail to play with Dash.js.
Is this a syntax issue or an issue with the input encoding? Using version 0.5.1-DEV-rev4065.

It seems that if i specify -lang eng in the command sometimes it will not change the language of the track.
For example if i do mp4box -lang fr '.\Avengers Age of Ultron(2015).mp4' on a file that has eng tagged stream it will not change it to fr it will stay at eng.
it seems that it might be when you go between a 2 letter code and a 3 letter code it will not make the change.

The expected mimeType value for text streams is `application/mp4`.

I have Windows 10 64-bit and am using 64-bit builds of mp4box
Builds after rev673 pop up error box with the message "mp4box.exe has stopped working"
when extracting video from an mp4 file. I'm wondering if this has to do with the reduced file size
of mp4box.exe. In rev673 the file size of mp4box.exe was ~512kb, while in the newer revisions
the file size of mp4box.exe is ~111kb. Is an extra support file required, or a different version of
the mscvcr runtime dll? Thanks.

Hello,
Is it possible to use GPAC apps to capture the live multicast stream to MPEG-DASH files directly, on the fly?
I tried to use DashCast application and MP4Box wit "grab-ts" otpion but I was able to capture the stream to single file. I wonder If there is a way to save it into DASH format directly.
Thank you,
Martin

Hi gpac team,
This is a question (from someone new to DASH) rather than an issue.
I'm using MP4Box to package DASH for a customer who is developing an iOS app to stream DASH + WVM + Google iOS WV SDK with a native player.
These encrypted DASH streams are playing out fine on Chrome Desktop and Android, but on iOS (in the above context) playout is failing with this message - "Cannot parse version 2 of Sidx".
This is triggered in the Google WV library - https://github.com/google/universal-dash-transmuxer/blob/master/library/dash/sidx_contents.cc - and (as I'm sure you are aware) is related to the version of the sidx (SegmentIndexBox).
I'm having a separate discussion with the developer of the universal-dash-transmuxer who is being very helpful, and is looking at potentially updating the code.
But in the meantime, (and this is my question for your team), when I'm using MP4Box to package to DASH are there ways in which I can affect the value of the sidx version?
If I could easily generate DASH with either sidx version 0 or version 2 that would be extremely useful.
I can't see a specific MP4Box param for this - I'm thinking that perhaps there might be a particular combination of settings that inform this value?
Many thanks.

I hope this is the right place to ask about this.
I'm trying to play a video that I've CENC-encrypted using MP4box with these options:
```
MP4Box -crypt drm_file_gpac_clear.xml BigBuckBunny.mp4 -out BigBuckBunny_cenc.mp4
```
Where the XML file specifies clearKey encryption. It's taken from GPAC's website https://gpac.wp.mines-telecom.fr/mp4box/encryption/common-encryption/
```
<?xml version="1.0" encoding="UTF-8"?>
<GPACDRM type="CENC AES-CTR">
<!-- example for GPAC 'clear' DRM System - keys are listed after the content and UL follows
The BS element from NHML syntax is used to describe what needs to be written in the PSSH box. In this example, the PSSH block contains:

</CrypTrack>
</GPACDRM>
```
To play this back, I have an HTML file which includes a video tag that specifies the encrypted file:
```
<video autoplay id="video1" controls src="BigBuckBunny_cenc.mp4" type="video/mp4"></video>
```
And some attached JS:
```
var KEY = new Uint8Array([
0xcc, 0xc0, 0xf2, 0xb3, 0xb2, 0x79, 0x92, 0x64, // this is key for MP4 file
0x96, 0xa7, 0xf5, 0xd2, 0x5d, 0xa6, 0x92, 0xf6 // encrypted with drm_file_gpac_clear.xml
]);
var config = [
{
initDataType: "cenc",
videoType: "video/mp4",
}
];
var video = document.getElementById('video1');
video.addEventListener('encrypted', handleEncrypted, false);
```
My problem is that the 'encrypted' event isn't fired.
This plays fine if I put an unencrypted file in place of the encrypted one, and it also plays fine if I substitute a WEBM file (from http://simpl.info/eme/clearkey/ ) and change the key and config accordingly ("view page source" on that URL for the details). So it will play back an encrypted file (in this case the 'encrypted' event is fired, of course), but not one I've encrypted with MP4box.
Also, when I play back the encrypted file, the unencrypted audio track plays OK; but the video is blank.
I've tried it in IE 11.0.9600.18036, Firefox 41.0, Chrome 45.0.2454.93 m and Chrome 47.0.2516.0 canary (64-bit).
I had a look at the MP4 file with MP4 Explorer, and it has the boxes I've been told to expect, such as encv, sinf and schm.
I've only been trying to learn about CENC during the last few weeks so this is all comparatively new, and I may have made some obvious mistake. If anyone can help, I'd be grateful for any advice.
Thanks!

The crashes are not 100% reproducible even with the same data set - sometimes it actually finishes execution successfully. Most times, the Windows crash dialog pops up. Visual Studio informs me that the error is:
```

I have multiple representations, not all with the same sample aspect ratio but all with display aspect ratio 16:9 (as verified by FFmpeg). I would thus expect that the `AdaptationSet@par` attribute generated by mp4box be `16:9`, since according to the DASH specification, it should take into account the sample aspect ratio.
However, the reality is that the value of this attribute is the picture aspect ratio from the last representation, without taking the sample aspect ratio into account.
FFmpeg output for this stream, showing example sar/par and picture size:
```
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv), 852x480 [SAR 640:639 DAR 16:9], 1157 kb/s, 23.98 fps, 23.98 tbr, 2997 tbn, 47.95 tbc (default)

Hello,
Who can give me a guideline about the title.
Because the segments that pruduct by Dashcast with the -live options, can not played by the dash.js player.
Thanks so much.

DashCast transcode a live stream in multiple qualities on windows7 64bit，and played these stream in the DASH.js.

Hello,
I found that the duration is strange, when I use the DashCast in the windows.
After I use this command
dashcast -vf dshow -vres 1280x720 -vfr 24 -v video="screen-capture-recorder" -npts -low-delay -time-shift -1 -live -mpd-refresh 2 -seg-dur 2000
, the duration in the MPD file is 48;
After I use this command
dashcast -vf dshow -vres 1280x720 -vfr 24 -v video="screen-capture-recorder" -npts -low-delay -time-shift -1 -live -mpd-refresh 2 -seg-dur 1000
, the duration in the MPD file is 24;
Is that right?
JamesXu.

I have built MP4Box on Ubuntu 12.04 64-bits and want to convert **subtitles.vtt** to SRT format:
**subtitles.vtt:**
```
WEBVTT
00:00:01.320 --> 00:00:07.680
- Så er vi kommet til Dyrehaven.
- Yes. Dyrehaven nord for København.
00:00:07.800 --> 00:00:09.840
- Det bliver en stor dag.
- Ja.
00:00:09.960 --> 00:00:14.400
- Vi skal have fundet noget forladt.
- Det skal vi.
00:00:17.720 --> 00:00:20.040
Det er perfekt.
00:00:23.400 --> 00:00:28.840
Det er den knold der.
Det ligner jo ikke et fort.
```
```
$ MP4Box -srt subtitles.vtt
WebVTT import
Conversion done
```
MP4Box does not generate any error messages, but the output file is incorrect:
**subtitles.srt:**
```
1
00:00:00,000 --> 00:00:01,320
2
00:00:01,320 --> 00:00:07,680
3
00:00:07,680 --> 00:00:07,800
4
00:00:07,800 --> 00:00:09,840
5
00:00:09,840 --> 00:00:09,960
6
00:00:09,960 --> 00:00:14,400
7
00:00:14,400 --> 00:00:17,720
8
00:00:17,720 --> 00:00:20,040
9
00:00:20,040 --> 00:00:23,400
10
00:00:23,400 --> 00:00:28,840
```
```
