As you may now, there are several ways to capture the screen using FFMPEG. One is to use GDIGrab device (like you have described for X11 with x11grab). If you want to know how to use it, visit [official FFMPEG devices page](https://www.ffmpeg.org/ffmpeg-devices.html#gdigrab).
But after using latest nightly binaries of GPAC for Windows, I found out that those binaries don't support GDIGrab! Saying it is an unknown video format!
Please fix it as soon as possible, as it is quite necessary for screen streaming on Windows.
Thanks.

Hello,
I am trying to create MPEG DASH MPD file supporting SRD based on multi-tile H.265 input (so that the result should be similar to: http://download.tsi.telecom-paristech.fr/gpac/SRD/srd_hevc/multi_rate_p60/hevc_srd.mpd)
The HEVC file was encoded with 8x8 uniformly spaced tiles.
However, I am not successful with generating MPD which contains proper tile information, I have tried the following:
Approach 1:
MP4Box -v -add test_multitile.hevc:FMT=HEVC -fps 30 -new test_multitile.mp4
MP4Box -dash 1000 test_multitile.mp4
^ The result is a MPD file without SRD support
Approach 2:
MP4Box -v -add test_multitile.hevc:FMT=HEVC:split_tiles -fps 30 -new test_multitile.mp4
MP4Box -dash 1000 test_multitile.mp4
^ The result is a MPD file with two adaptation sets with SRD, but with incorrect dimensions (first one is the full resolution: 3840x2160, second one is 448x256)
I am obviously doing something wrong.
Can somebody please help me how to properly mux the multi-tile HEVC stream and create the DASH MPD with MP4Box?
Thank you!

I'm experimenting with Dashcast.
My objective of creating MPEG Dash live streaming services (input rtmp, output DASH live available on a portal) At the moment I use as input files in loop mode.
I have issues to have the the stream playing not interrupted using both dash.js and bitmovin players setting the segment size under 16 sec.
Here follow the dashcast command I currently use (working config):
DashCast -conf dashcast.conf -v video10.mp4 -a AudioEng.m4a -npts -mpd-refresh 2 -seg-dur 16000 -live-media -low-delay -out /home/fgiuffrida/SOURCES/ECODEMO/dashcasttest/output -mpd stream.mpd -time-shift 120 -min-buffer 1.0
the dashcast.conf is:
[v1]
type=video
framerate=25
width=720
height=576
bitrate=2482000
codec=libx264
[a1]
type=audio
bitrate=128000
codec=aac
channels=2
samplerate=44000
My input for now are a video file 25 fps and the related audio aac 128k/44100
Audio video quality is good, video keep in sync and ho noises as it is 44100
I tried with chrome and firefox, chrome look more reliable.
Thanks
Francesco.

Hi,
I was interested to know if it is possible to create dynamic tiles (like changing position or size) for mpeg DASH to stream. I know the corresponding command to create normal tiles in MP4Box and by the looks of it, such an action is not possible (yet, maybe for future?). yet I was wondering if it is even possible to create and stream dynamic tiles in DASH. I couldn't find anything in mpeg DASH's specification regarding the possibility of such a thing in DASH's concept.
Regards

Hello,
I'm not sure if it's an issue, but I have a question about the way CENS Pattern Encryption is implemented in the latest GPAC:
The question relates to handling of partial encrypted blocks overlapping the end of a NAL SubSample (e.g. the BytesOfProtectedData of the subsample). I have noticed that GPAC pads the incomplete block and still applies the AES-128-CTR encryption on the padded block. The padding of the encrypted block is then removed, and the partial encrypted block stored at the end of the subsample pattern.
I was wondering if this is correct according standard (Common Encryption, ISO/IEC 23001-7, 3rd edition, June 2015). In fact, according standard (section 10.3), "The BytesOfProtectedData size SHALL be a multiple of 16 bytes to avoid partial cipher blocks in Subsamples". So, that case should in fact not happen and GPAC should not have generated a SENC box with non-block aligned clear/protected sections in a subsample.
Still in case it happens, section 9.6.1 says: "If the last Block pattern in a Subsample is incomplete, the partial pattern SHALL be followed until truncated by the BytesOfProtectedData size, and any partial crypt_byte_block SHALL remain unencrypted."
Do you care to comment on that point?
Thanks in advance and best regards,
Thierry Bertschi

Hi,
I was interested to know the corresponding command to create a tiled video. I have already created a normal DASH sequence with various qualities using MP4Box (which generates the *.mpd file), yet I don't know how to tell MP4Box that i want to create a tiled video that contains a different sequence in each tile. I've seen the demos like "tears of steel", yet i couldn't find any tutorial on how to create a tiled video and what command or commands to use to tell MP4Box that the videos that are provided to it need to be put together as tiles (or which sequence needs to be played in which tile).
Thanks in advance

Need help in debugging why dashing with mp4box is introducing an AV sync issue.
Repro steps:
MP4Box -dash 2000 -profile dashavc264:onDemand -bs-switching no -rap -frag-rap -out manifest_audio.mpd musk_sd.mp4#audio
MP4Box -dash 2000 -profile dashavc264:onDemand -bs-switching no -rap -frag-rap -out manifest_video.mpd musk_sd.mp4#video
Then I combined the MPDs as in attached manifest_combined.mpd and tried to playback with mp4client. AV sync issue repros.

Currently each timed element is put into its own sample, with the whole XML boilerplate around it. That's repetitive, wasteful and usually not required.
It would be good to at least have an parameter to override this, and e.g. write the whole TTML stream into a single sample, or all timed elements for a single MP4 fragment into a single sample inside that fragment, or e.g. make samples of 1 minute duration.

TTML muxing should be able to merge timed elements

This results in an invalid stream. `<p>` right below `<body>` is not allowed by the spec, and the `<p>` must be wrapped in a `<div>` instead.

Hello,
Am implementing an adaptive streaming adaptation algorithm using gpac and have been looking at the dash_do_rate_adaptation function. Please am trying to figure out how and when the MP4Client decides to get the next chunk while playing the current chunk. Does this happen immediately after downloading the current segment, does it wait after a period of time or just based on the current buffer occupancy? Any help will be appreciated to know where(function) and when this decision takes place.
Thank you.

Hi,
I am trying to dash a video only mp4 with the following command:
MP4Box -dash 2000 -profile dashavc264:onDemand -bs-switching no -rap -frag-rap -out manifest.mpd video.mp4
Before running mp4box, the pts and dts of the frames start at 0. After running mp4box, the pts and dts of all frames are moved by 67ms.
I am seeing the exact 67 ms added to several different video streams that I run the above command on. Attached is the ffprobe show_frames output of the video before and after running mp4box.
[before.txt.zip](https://github.com/gpac/gpac/files/501742/before.txt.zip)
[after.txt.zip](https://github.com/gpac/gpac/files/501743/after.txt.zip)
Before running mp4box, I demux the audio and video streams using ffmpeg and use MP4Box to dash the streams separately. MP4Box does not change the pts and dts of audio stream but sometimes, MP4Box adds the 67ms offset to the video stream. When it does, there is an AV sync issue when I put the audio and video MPDs together.
Please help me understand where the 67ms offset comes from.

The ISOBMFF module supports parsing either:
- from an ISOBMFF file that contains all bytes from its beginning (including ftyp, moov ...), possibly growing;
- or from multiple ISOBMFF segments being fed to it as files or memory buffers. The data has to be box-aligned, and even movie fragment aligned. It does not do the box/fragment-alignment nor the garbage collecting of the data. This is done implicitely by the MPD/HLS module.
These two modes do not allow for playback of a plain HTTP long-running download (i.e. not using the cache, and not using the DASH module) of a fragmented mp4 such as http://patchy.ddvtech.com:8080/live.mp4.
The module should create its own memory buffer when receiving non-cached data, split the data at fragments boundary, parse and discard fragments as they are discovered, whether the transfer is chunked or not.

- [X] I tried with the latest version of GPAC. Installers available at http://gpac.io/downloads/gpac-nightly-builds/
- [X] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...). I can share files anonymously with this dropbox: https://www.mediafire.com/filedrop/filedrop_hosted.php?drop=eec9e058a9486fe4e99c33021481d9e1826ca9dbc242a6cfaab0fe95da5e5d95
I'm using gpac version b60f90a92c38b3aaf10b41533e25a14f1c6c3f3a. I have uploaded an example file demonstrating the issue with the description "GPAC issue custom sample descriptor example file".
Reproducing the issue:
```
MP4Box -v -diso gpac-custom-sample-desciptor.mp4
```
This will result in the following output (among the rest):
```
...
[iso file] Read Box type uri size 44 start 8
[iso file] Read Box type uriI size 28 start 52
[iso file] Warning Read Box type .... (0x00000000) size 0 - patching to size=8 ...
[iso file] Read Box type .... size 8 start 80
[iso file] Box "...." has 8 extra bytes
[iso file] Read Box type trak size 888 start 1896
...
```
It also results in the following output in the produced XML:
```
<SampleDescriptionBox DataReferenceIndex="1" ExtensionDataSize="0">
<BoxInfo Size="0" Type="urim"/>
<UnknownBox>
<BoxInfo Size="44" Type="uri "/>
</UnknownBox>
<UnknownBox>
<BoxInfo Size="28" Type="uriI"/>
</UnknownBox>
<UnknownBox>
<BoxInfo Size="8" Type="...."/>
</UnknownBox>
</SampleDescriptionBox>
```
The reason why it finds 8 extra bytes is this piece of code (src/isomedia/box_code_base.c starting from line 6613) starts here:
```
GF_GenericSampleEntryBox *genm;
/*remove entry*/
gf_list_rem(trak->Media->information->sampleTable->SampleDescription->other_boxes, i-1);
genm = (GF_GenericSampleEntryBox *) gf_isom_box_new(GF_ISOM_BOX_TYPE_GNRM);
genm->size = a->size-8; <---
bs = gf_bs_new(a->data, a->dataSize, GF_BITSTREAM_READ);
gf_bs_read_data(bs, genm->reserved, 6);
genm->dataReferenceIndex = gf_bs_read_u16(bs);
```
Here the parent box size is set to the box size minus the box header (size+type). Then the code reads 6 reserved bytes plus 2 bytes for the data reference index. So now the box has 8 fewer bytes to process for the remaining boxes. Next the remaining bytes are processed:
```
if (gf_bs_available(bs)) {
u64 pos = gf_bs_get_position(bs);
//try to parse as boxes
GF_Err e = gf_isom_read_box_list((GF_Box *) genm, bs, mp4s_AddBox);
```
The function gf_isom_read_box_list_ex then loops until the parent box size is consumed:
```
while (parent->size) {
e = gf_isom_parse_box_ex(&a, bs, parent_type, GF_FALSE);
...
if (parent->size < a->size) {
...
} else {
parent->size -= a->size;
}
...
}
return GF_OK;
```
However, once it has processed all the boxes, there are still 8 bytes left (that were already parsed for the reserved bytes and data reference index). This results in it finding an empty box with no size (the buffer seems to contain zeroes instead of the actual content in the file).
It seems to me the appropriate solution would be to arrange the genm box to have a size 8 fewer than it currently is before entering the gf_isom_read_box_list function.
The reason why ie. GF_ISOM_MEDIA_AUDIO processing doesn't have the same issue is that the gf_isom_audio_sample_entry_read function it calls reduces the parent box size when it reads it. But the same parent box size reduction doesn't happen in the default switch.
Thanks and keep up the good work!

Hi, i am using mp4box + darwin streaming server as rtsp server, they runs ok before. But a day ago, mp4box hint a large mp4 file report a error:
```
Hinting file with Path-MTU 1450 Bytes
[ODF] Error reading descriptor (tag 6 size 16): Invalid MPEG-4 Descriptor
Hinting track ID 1 - Type "mp4v:mp4v" (MP4V-ES) - BW 4350 kbps

```
the command is : mp4box.exe -hint f1.mp4
the size of f1.mp4 is 2.86G
i tried some other files, and found if the file is bigger than 2G , mp4box would printf error like above.
the version of mp4box is latest, and the exe is built through gpac_mp4box_mini project
am i some thing missing or the command is wrong?

Hi, many 3D camcorders like the JVC GS-TD1 store MVC video in MP4 files. Some sample files are [ez0027.mp4](http://av.watch.impress.co.jp/video/avw/docs/424/208/ez0027.mp4) and [ez0028.mp4](http://av.watch.impress.co.jp/video/avw/docs/424/208/ez0028.mp4) in this [web page](http://av.watch.impress.co.jp/docs/series/zooma/424208.html). These files have both views stored in the same track. There are MVC-specific `mvci`, `mvcg`, `vwid` and `mvcC` boxes in the track. I can confirm that Cyberlink PowerDVD automatically plays these files in 3D when I open them.
When I tried muxing a raw MVC stream with MP4Box, it created a MP4 file with a `svcC` box, and it cannot be played in 3D. It also displayed the following error.
`[avc-h264] MVC not supported - skipping parsing end of Subset SPS`
Since SVC muxing support is already implemented in MP4Box, and SVC and MVC have similar NAL units, would it be possible to support MVC muxing too? There is a free MVC encoder / decoder available now (Intel Media SDK with its command-line front end [FRIM](http://forum.doom9.org/showthread.php?t=169651)). It would be great if MP4Box could support MVC muxing / demuxing as well. (GPAC version: `0.6.1-rev0-g72d766c-master`)

Command: `mp4box -dash-strict 4000 -profile "dashavc264:live" -bs-switching no -sample-groups-traf audio2.mp4 -out out\Manifest.mpd`
Version: gpac-0.6.2-DEV-rev723-g321745c-master-x64
Input file: [audio2.zip](https://github.com/gpac/gpac/files/466731/audio2.zip)
The input is an encrypted audio track using the HE-AACv2 codec. The size of the sample aux information is marked as 8 in the saiz box (this is correct).
After dashing with the above command, the saiz box claims a sample aux information of 10 bytes, which is incorrect.

I am trying to convert a .m3u8 manifest to .mpd manifest.
For this purpose, I use the following command :
> MP4Box -mpd master.m3u8
You can find the master.m3u8 file attached here [[master.m3u8.zip](https://github.com/gpac/gpac/files/463897/master.m3u8.zip)].
Normally, this works. But whenever the .m3u8 file has a **EXT-X-KEY** method in it, the command does not work. That is whenever such an option is present:
> # EXT-X-KEY:METHOD=AES-128,URI="https://priv.example.com/key.php?r=52", \
>
> IV=0x9c7db8778570d05c3177c349fd9236aa
The code crashes, by generating an half-completed master.mpd file : [master.mpd.zip](https://github.com/gpac/gpac/files/463909/master.mpd.zip)
The log file is attached below :
[mp4box-bug-log.txt](https://github.com/gpac/gpac/files/463913/mp4box-bug-log.txt)

I use the following MP4Box command to generate the manifest file(.mpd). The manifest file is common to different video representations.
```
MP4Box -dash 5000 -frag 5000 -fps 25 -frag-rap -rap -bs-switching merge -profile dashavc264:live -mpd-title "Mpeg Dash Preview" -segment-ext null -segment-name seg_ -out test.mpd resolution_480p.mp4#video:baseURL=./v/ resolution_360p.mp4#video:baseURL=./v_360/ resolution_720p.mp4#video:baseURL=./v_720/ resolution_480p.mp4#audio:baseURL=./a/
```
Though dash.js is playing the video, only single bitrate is being played without switching the resolution according to network condition. Am I missing something in the command? or should I enable Adaptive Bitrate Switching in the player?

The filesizes are (much) smaller than the filesizes of the 32-bit installers.
Also: please stop wrapping the dämn files in an installer.
Stop complicating everything, Many users like myself are interested only in MP4Box, and manually unpacking the stupid installers is a P.I.T.A. Just wrap the files in a .ZIP or .7Z archive, problem solved.

I read from a paper that a plugin can be installed in Firefox:
"To support the DASH process on the client, then the client browser must be done to support the installation of a browser plug-in that can perform H.265 video play out at the client. In this case use Osmozilla plug-in version 1.0.1.0 which is the product of the GPAC. "
Anyone knows how it works?

Hi, I would like more information about GPAC.
I need a tool that can encode / decode a video. The aim is to be the only one able to read the video. A bit like "my own codec".
Do you think it is possible to change the GPAC's code to do this ? Or maybe it already exists ?
Thanks.

Hello there,
I will get to the point straightaway,
When I make a live streaming using x.265, i recieve segments very fine at the client side (By using MP4Client). However, when I make VoD, I receive a message that "Cannot open http://<ip address of the server>/dash/dashvod/dashcast.mpd: Bad Parameter", although the time at both sides exactly the same (UTC zonetime).
I use the following commands at the server side:
⦁ ffmpeg -i <path&name of videofile> -c:v rawvideo -s:v 1280x720 -r 25 -pix_fmt yuv420p output.yuv
⦁ ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1280x720 -r 25 -i output.yuv -c:v libx265 -f rawvideo output.265
⦁ MP4Box -add output.265 output.h265
⦁ DashCast -v output.h265 -seg-dur 10000 -out /opt/lampp/htdocs/dash -conf dashcast.conf
At the Client side (Windows 8.1 OS):
⦁ mp4client http://<ip address of the server>/dash/dashvod/dashcast.mpd
Please find the attached files

I'm using Dashcast on Ubuntu 16. I've tried it on the latest build of Gpac, but it still seems to happen. Is this a resource issue? Because dash.js and shaka both have issues with reading live streams with missing segments, so it tends to break at the beginning of the video.
My command is 'DashCast -v bunny.avi -out output/ -live-media', and I've tried with ntps, mpd-refresh, low-delay and a few others, but nothing seems to have an effect.
Looking at the source code, this seems to be caused by the 2nd while loop in 'video_encoder_thread' in 'controler.c', line 731, which seems to be buffering frames too long.
Any ideas on how to fix?

Hello there,
I am trying to make a live streaming using x265
I sat up all the system on Linux Ubuntu, and when I start streaming, i find that the output folder doesn't have an .mpd file so I cannot get this live streaming at the client side
the command I use is:
acer@acer-Aspire-4741:~/dash/gpac-master/applications/dashcast$ DashCast -vf video4linux2 -vres 1280x800 -vfr 30 -v4l2f yuyv -v /dev/video0 -live -out /opt/lampp/htdocs/dash -conf dashcast.conf -seg-dur 1000^C
|
No .mpd file is generated

When I try to mux a TTML XML file with associated PNG subtitles, MP4Box shows the following error.
`[EBU-TTD] No sample imported. Might be an error. Check your content.`
But muxing TTML text subtitles works correctly. My GPAC software's version is `0.6.1-rev0-g72d766c-master`.

I hope to use ctrl+h and ctrl+l to adjust the video quality when I use the mp4client to playback a .mpd file. However, it does not work. The mp4client playback for each video works. The video quality adaption for AVC works. Only the adaption for HEVC does not work.
Here is the sentence I used to generate the .MPD file:
mp4box -dash 960 -profile live -rap -frag-rap -url-template -bs-switching no -segment-name $RepresentationID$-$Number$ -lf mp4client-bug-log1.txt -logs all@debug -out HD.mpd CandleSmoke_scaled_1920.mp4 CandleSmoke_scaled_3840.mp4
The GOP is 8.

Hi,I am a beginner in this area, I know this is not a bug but forgive me in advance because I really think this thing for a long time. My professor told me to build a streaming system that using webcam or MP4 file through the dashcast transfer to a server( so is my localhost, which is /var/www/html,etc), and says that all the people can access the address on my localhost to see my streaming.
And I am using this code currently:
DashCast -v /var/www/html/test1.mp4 -seg-dur 500 -live-media -out output -mpd /var/www/html/test1.mpd
It gives me a lot of [dashcast] Live system dropped a video frame
And [Core] system failure for file opening of output//var/www/html/test1.mpd in mode w: 2
Would you guys please give me some guidances? About this? Or give me an example to follow, because I am really eager to know the answer of it.

Hi all,
I am trying to perform a screen+sound capture and stream as a mpeg-dash feed with DashCast. When I try to capture sound from m laptops microphone I get the following message:
**[AVAudioResampleContext @ 0x7f8984000c60] Invalid input channel layout: 0
Could not open the audio resampler. Aborting.
An error occurred while reading audio frame.**
The command I use is DashCast -vf x11grab -vfr 25 -v :1.0 -a plughw:1,0 -af alsa -npts -time-shift -1 -low-delay -frag-dur 1000 -seg-dur 1000 -live
Is there any way I can specify which channel layout to use? Also, if I wish to intercept audio playing through my sound card and use it for the dash stream what would I have to type?
Thanks.
Version: 0.5.2 -426-gc5ad4e4+dfsg5-1build1

I seem to be getting INCORRECT return codes occasionally from within my CMD batch script when using: MP4Box -brand
I'm guessing that very occasionally Windows may not have quite released the Write Process Lock after the previous CMD statement writing an mp4 file.
MP4Box -brand should be overwriting my original file, and I note it uses this process:
It first creates a temporary file named with the prefix 'out_' e.g. out_file.mp4
Then it tries to remove/delete the original file.
Then rename the temporary file to the original name.
WHEN THIS PROCESS FAILS IT STILL RETURNS A RETURN CODE OF 0 (for SUCCESS)
(e.g if the original file is read-only, or perhaps it's still locked because it's not yet been released by Windows writing process, or maybe even a read error when trying to execute the command internally.)
I tested this by making the original file read-only. MP4Box -brand failed of course. But I still got a Return Code of 0 for success.
I am mis-interpreting this problem? Or if not, then perhaps a default failed Return Code of 1 should be pre-set internally until MP4Box completes it's processing, and then finally a Return 0 issued only if it has definitely completed successfully.
Please advise.

Hi! I want to install GPAC 0.5.0 version on Ubuntu MATE on Odroid XU4. I only use this version because -dev versions have some bugs when merging videos). So far, I have successfully installed it on Rasbian and Ubuntu 14.04. but I have problems when trying to install it on this distro for Odroid.
I have .zip file with 0.5.0 version and what I am doing is, after I extract it:
```

Issue description :
DashCast couldn't generate any segment files, init file and mpd file for input Stream of UDP/RTSP from VLC player
You can reproduce this issue with following steps :
Test Case 1. : Not working
// Transcode the input stream, display the transcoded stream and send it to a multicast IP address
%vlc -vvv Animation.mp4 --network-caching=10 --sout '#transcode{vcodec=h264,venc=x264{keyint=25,idrinit=25,bframes=0,ref=1,hrd=cbr,crf=28,vb=4500,preset=ultrafast,tune=zerolatency,vbv-maxrate=5500},fps=25.00,threads=48,deinterlace,audio-sync}:duplicate{dst=display,dst=udp{caching=10,mux=ts,dst=127.0.0.1:9092,name="testTS2"}}'
// To capture UDP streams and transcode and segment it in 1000-millisecond segments for a live service:
# DashCast -v "udp://@127.0.0.1:9092?fifo_size=100000" -live -low-delay -frag 200 -insert-utc -seg-marker eods -min-buffer 0.2 -ast-offset -800 -pixf yuv420p
Test Case 2 : Not working
// Transcode the input stream, display the transcoded stream and send it to RTP Streams
% vlc -vvv Animation.mp4 --sout='#transcode{vcodec=h264,vb=0,scale=0}:duplicate{dst=display,dst=rtp{sdp=rtsp://:8554/session.sdp}}'
// To capture RTP streams and segment it, stored the log to log.txt
DashCast -v rtsp://@localhost:8554/session.sdp -live -log-file log.txt
Test Case 3 : Not working
// Without Transcode the input stream, display the transcoded stream and send it to RTP Streams
% vlc -vvv Animation.mp4 --sout='#duplicate{dst=display,dst=rtp{sdp=rtsp://:8554/session.sdp}}'
// To capture RTP streams and segment it, stored the log to log.txt
DashCast -v rtsp://@localhost:8554/session.sdp -live -log-file log.txt

According to the ISO BMFF spec, Section 8.9.4, the group description indexes in the 'sbgp' boxes must start at 0x10001. i.e., 65537
[](https://sourceforge.net/p/gpac/bugs/300/)
Please confirm which GPAC software release have the fix for this

when generate the dash segment by using GPAC, sbgp box's group description index is turns into 1 instead of 65537

Dashcast can take inputs from files or URLs, but if I would like to integrate it into another program, can it take as input a buffer and output to another buffer or a socket?
I've been looking at the code and it seems like it is mainly for cli, or am I wrong?

[GPAC's DASH sequences](https://gpac.wp.mines-telecom.fr/2012/02/23/dash-sequences/) cause decoder errors on Safari. For example, ["live profile with bitstream switching support, Audio+Video"](http://download.tsi.telecom-paristech.fr/gpac/DASH_CONFORMANCE/TelecomParisTech/mp4-live/mp4-live-mpd-AV-BS.mpd) and ["main profile, multiple files with bitstream switching support, Audio+Video"](http://download.tsi.telecom-paristech.fr/gpac/DASH_CONFORMANCE/TelecomParisTech/mp4-main-multi/mp4-main-multi-mpd-AV-BS.mpd). (We have not exhaustively tested all sequences GPAC hosts, so there may be others.)
[Shaka Player](https://github.com/google/shaka-player) is using these as test vectors to ensure compatibility with GPAC, but our tests for these fail on Safari. As far as we can tell, there are two features that make the failing GPAC vectors unique in our tests: multiple SPS/PPS in the init segments, and no sample duration.
Would you consider regenerating your vectors without these features for Safari compatibility? Or if you don't want to completely replace them, would you consider generating variants of these vectors that work with Safari?
Since these work fine on Chrome and Firefox on Mac, I am about to file a bug on WebKit about this. I will update here with a link once I've done so.

Simple Summary: Concatenating two files with chapters together, using the latest version of MP4Box (MP4Box - GPAC version 0.6.2-DEV-rev681-g32e98cd-master) results in the chapter track being longer than the video/audio tracks which results in the total duration of the file being wrongly reported.
I've been producing M4V files using Handbrake (version 0.10.2 for x86_64) that have a chapter track. Each are produced using the normal profile with the extra settings of web optomised and fast deinterlace. Each of these files, on their own, work flawlessly in a number of media players. On occasion I want to concetenate two or more of these files together to produce a single file. After some experimentation I've been doing this using MP4Box with the following command line (Note that usually the -force-cat option isn't really needed and it appears to make no difference to the following anyway):
```
MP4Box -force-cat -cat part1.m4v part2.m4v -new merged.m4v
```
When I then open the merged file I find that the length of the video is longer than the sum of the two parts. The exact extra duration seems to vary and I haven't yet spotted any obvious patterns. This happens with every set of files I've tried that have a chapter track. The result is that the video plays normally but ends before it's reached the stated duration, but at the point you would expect if you simply add the lengths of the two parts together. It also means that if you seak past the actual end some players get rather upset!
As an example here is the output from -info for two input files

Here you can see that both the video and audio tracks are 03:38:48 in length which matches the sum of the lengths of the two parts. The chapter track is shown as having an "indicated duration" of 03:19:57 but a "track duration" of 03:46:33 which is approximately 8 minutes longer than it should be. When this file is played the length is reported as 3 hours and 46 minutes, but if you try and watch or seek past 03:38:48 it causes the player to stop, which makes sense as there is no audio or video data.
My feeling is that there is a bug somewhere in the concatenation of the two chapter tracks causing the duration to be wrongly reported.
I have figured out a work around which might allow you to shed some light on the issue. Once I have the merged file I extract the chapter information to a TTXT file using the command
```
MP4Box -ttxt 3 merged.m4v
```
The resulting file looks fine and the last TextSample element has a sampleTime of 03:19:57.857 matching the indicated duration of the track.
The final stage is then to combine the audio and video from the merged file with this chapter track using the command
```
MP4Box -add merged.m4v#video -add merged.m4v#audio -add merged_3_text.ttxt:chap -new final.m4v
```
Extracting the info from this file gives

As you can see the chapter track now has an indicated duration that matches the audio and video tracks and this file plays perfectly in the media players I've tried. The only differences I can see are that the chapter track no longer has an edit list and is reported as type text:tx3g instead of text:text as well as the TimeScale being 1000 instead of 90000, but I'm not sure if any of those would cause the issue.

Hi
I have a Sansa Clip Jam player that doesn't handle m4a files very well.
If I mux the aac files to m4a with FFmpeg it won't play them at all.
If I mux the aac files to m4a with mp4creator 1.6.1e-pre it will play them, but only if they are not more than 30 minutes duration.
If I mux the aac files to m4a with MP4Box it will play them, but only if they are not more than 11 minutes duration.
I have uploaded to MediaFire a 30 minute m4a file muxed with mp4creator that plays OK with the SandDisk "tester.m4a".
Is there a setting for MP4Box that will allow me to play longer files with the SanDisk?
|
Is it possible to mux longer m4a files with MP4Box that will play with low-spec SanDisk.

This happens because function "atof" is used (log from Android Monitor at the end).
[Apparently](https://groups.google.com/forum/#!topic/android-ndk/RjO9WmG9pfE), when building for Android API > 19 by default some inline functions are not included since they are in "libc.so" (the Bionic C library used by Android).
However, we are building for API 18 (4.3.1), so I assume that that this is a new undocumented "feature" of the latest NDK (12b).
In order to be able to build, NDK r11c (or earlier) must be used.
Donwload link for NDK r11c (Linux): http://dl.google.com/android/repository/android-ndk-r11c-linux-x86_64.zip
Donwload link for NDK r11c (OS X): http://dl.google.com/android/repository/android-ndk-r11c-darwin-x86_64.zip
P.S. Maybe we should update the documentation until it's fixed

I am using mp4Box to package the mp4 files to DASH using.
One is mv_dash.mpd, another is mv_dashinit.mp4.
Then I put it on the Amazon S3 server and get the mpd file URL link as
https://s3-ap-southeast-1.amazonaws.com/dash1029/media/mp4box/mv_dash.mpd.
When I using DASHIF client player (http://dashif.org/reference/players/javascript/v2.2.0/samples/dash-if-reference-player/index.html) to load the mv_dash.mpd file, the player seems no reactions.
But shaka-packager work!
Can anyone give some help? Thanks

I have been running an MP4 command line via a BAT file and it appears that if I specify the path using an address with periods - either an IP address or FQDM, the files created are missing file extensions, whereas if I use the "server name", the files are created with .mp4 extensions as expected.
Command Line Used:
`"C:\Program Files\GPAC\mp4box.exe" -single 2 -single 3 -single 4 -single 5 "\\192.168.3.5\old_nearline\TEST_1080P_2398_24CH.mp4"`
This was repeated with server name (`\\vault05\`) which created files with extensions, and also fully qualified domain name (`\\vault05.office.company-name.com\`) which again dropped the extensions.
No error messages given.
OS Tested = Windows 7 x64 and Windows Server 2008 R2 Standard (64bit)
Tested with:
gpac-0.6.1-rev0-g72d766c-master-x64.exe
gpac-0.6.2-DEV-rev673-gcf249c1-master-x64.exe
I've uploaded the above file to the MediaFire dropbox.
Many Thanks
Matt

I was trying to encrypt this video named "oggy.mp4".
For this purpose,
- Firstly I seperated audio and video from the audio using "raw" command.
- then I converted, two audio tracks to mp4 tracks.
- after that I encrypted the video, with file "oggy_encoder.xml"
- Finally I created the dash file using the encrypted video and unencrypted audio.
Now, there is problem with the audio in finally prepared file oggy_audio_dashinit.mp4.
Need help with this.
Attaching all the used files and logs by chrome(using shaka player).
I have uploaded zip file to media fire.

Hi
I have raw .264 stream encoded at 30000/1001 fps.
If I mux it "blindly" without -fps option, mp4box sets up 120000/4004.
If I mux with -fps=29.97, mp4box sets up 30000/1001.
Both are the same and correct, but why mp4box just not divide values to the lowest possible?
Similar with 25fps (25000/1000 instead of just 25/1).
Other timescale case, stream encoded at 2997/100 (round ntsc).
Mp4box sets up 11988/400 (as above 4 times higher).
But in this case I can't restore original 2997/100 timescale because fps=29.97 mp4box interprets as 30000/1001.
In this case It is impossible override framerate of ntsc_stream with framerate of rounded_ntsc_stream. (It's just few ms difference in 1hour clip, but it is incorrect, and rise with movie lenght).
It all could be fixed, if mp4box -fps allow specify it also as -fps=num:den (similar to -par style option).
Any thoughts?

While writing video decoding module for osmo4 for android. I was having some a/v sync issue with h.264 1080p. Due to this, I tried to set the CTS time but I cannot find its unit. It's not documented. https://github.com/gpac/gpac/blob/cb883bf55302ed5198b5cb1fd05648ad5de2006d/include/gpac/modules/codec.h#L245
Also, after experimenting I found it played 360p videos well without any issues. To make it work for 1080p, I tried to lower the duration for waiting for the input and output buffers to be available, it seems to eliminate sync issues but now video is lacking detail, colors looks faded and square blocks on most of the frame.

CENC describes 4 different encryption schemes, of which mp4box only supports a subset (only 'cenc', I believe?). I would like to request that support be added for the other encryption schemes, too, as they may become relevant in the near future (especially with fMP4-HLS).
This is implemented by [shaka-packager](https://github.com/google/shaka-packager/issues/78) - achieving feature-parity here would be nice.

Is there a way to do this using mp4box? I know you can add multiple representations within a single command to generate a single mpd, but can you update an existing mpd with mp4box to add in a new representation after the file is already generated? I couldn't find this information anywhere. Thanks.

File src/terminal/media_object.c in line 1487 contains a non-breaking space that makes compilation fail with at least MinGW GCC.
I'd suggest having a git hook to prevent committing these, if it can't be avoided in the editor.
With this command grep should highlight the location of the nbsp for easier removal:
``` bash
$ git grep -PIn ".?.?.?\xC2\xA0.?.?.?"
```

I and some others are not in a position to use an installer just to have mp4box available.
Would it be possible to create a non-installer standalone portable mp4box, nightly ?

Hi, I think mp4box slightly incorrect writes edit list in case of video positive delay.
Entry of delay (media_time=-1) is ok, but next entry of track starts from 0, while it should be set equal to ctts with b-frame stream (just like in not delayed video). media_time=0 causes a/v desync here.
I've played also for a while with negative vid delay option (b-framed streams).
Seems mp4box should increase in this case user defined delay by ctts/vid_timescale value.
If it only injects straight recalculated -delay, audio plays too early (time of ctts shift).
There's also impossibilty to set up negative delay when this delay is equal to ctts shift time (which entry is already written for synced playing).
What do you think?

Here's the file:
http://www82.zippyshare.com/v/wCIGnABa/file.html
AVC/H264 Video - Visual Size 852 x 480
and it's ok.
Now, after demuxing video to raw & import back to mp4:
AVC/H264 Video - Visual Size 858 x 480
and video has weird transparency at right side when played in MPC-HC (in Classic totally broken).
What's wrong?

I'm using MP4Box (0.6.2-DEV-rev591-g878a3f3-master) to package CENC encrypted mp4 files. I'm using Widevine for the DRM part and am trying to achieve playback on an iOS device using Widevine's iOS SDK. Now, playback on iOS has to go through a DASH to HLS transmux, which is ensured by [this library](https://github.com/google/universal-dash-transmuxer). But it seems the latter doesn't play well with 'saio' v1 box. A 'saio' v0 box that contains the same value for the offset works correctly. The location of it can remain exactly the same, just version of it is old which their transmuxer requires.
Obviously, I've first enquired about whether an udate of the transmuxer was planned, to accept v1 boxes. Meanwhile, I'm trying to find a workaround. Now, this is a silly and naive question, but is there a way to let MP4Box generates 'saio' v0 box? An older version of the software maybe?
Thanks a lot for your help.

Using GPAC version 0.6.2-DEV-rev576
I am packaging multiple mp4 files to DASH. All of the files are 16:9 aspect ratio but are being broken up into 2 different adaptation sets. I need to keep in one adaptation set.
For the 1920x1080 rendition (and others), PAR is being set to 16:9 and SAR is being set to 1:1. This is correct.
For the 412x236 rendition, the PAR is being set to 412:236 and the SAR is being set to 1:1. However, the PAR should be 16:9 and the SAR should be (412 \* 9) : (236 \* 16).
I believe this is what is causing the generation of the 2 different adaptation sets. It appears that there is a calculation error in mp4box.
Can you confirm?

I have been attempting to create a deterministic understanding of the timing logic used by mp4box, with the idea being to always have representations of the same length and not to have any "missing time" anywhere. In this exploration, I ran into a scenario that appears suspicious to me,
Version: gpac-0.6.2-DEV-rev591-g878a3f3-master-x64
Command executed: `mp4box -dash-strict 4000 -profile "dashavc264:live" -out Out\Manifest.mpd video.mp4`
Input file: [video.zip](https://github.com/gpac/gpac/files/314018/video.zip)
Description: this input contains a video stream that is 95 frames long, at 24 frames per second rate.
Output from this command:
- 1 media segment containing the 95 frames, with the duration in the manifest marked as 3.958s
- Manifest with the presentation duration marked as 3.95**9**s
```

</MPD>
```
Expected result: presentation duration is equal to the duration of the 1st and only segment.
From my observations, it would appear that the presentation duration is always rounded up, whereas in this case the segment duration is rounded down (from 3.9583333333...). This means that there exists 1 millisecond on the timeline that is not backed by any segment files.
Without deeper analysis, it sounds like always using the same rounding algorithm might perhaps correct this?

There is no visible command line output printed by mp4box in response to this command. Adding `-logs debug@all` produces this line (besides other seemingly uninteresting lines):
```
[DASH] No samples in movie, rewriting moof and exit

How to set a log file to store the logs that I see in the console when using MP4client with console?
Is this possible?
I noticed that in the configuration document that
"LogFile [value: filename]
Specifies where to output GPAC's log. By default, the logs are written to stdout. Note that GPAC may be compiled without log support. **This is not used by MP4Client**."
Thanks a lot.

Hi! I have problem with MP4Box, can't concatenate videos in one video. I get out.mp4 file (~103 MB) but omxplayer can not play it. I have 6 very simple .mp4 videos and I want them to merge in one video. Until now, I was able to do that with command, without any problems:
```
MP4Box -cat Awards\ -\ Recognitions\ Screens\ Video.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat DIOCLETIANS_BREAKFAST.mp4 -cat FLAVOURS_OF_DALMATIA.mp4 -cat Prognoza.mp4 -cat Restaurants\ -\ Bars\ 2016.mp4 -cat WineHappyHour3.mp4 -new out.mp4
```
but now omxplayer (also vlc) can not play out.mp4 video. Here is mediainfo output for every one of 6 videos:

So all 6 videos have good mediainfo output but anways I tried executing command to test without 1 video (one by one), and then merging them, but same result. I get strange command line output when I execute mp4box command:
```

As you can notice there are exactly "#" videos parts as "No suitable destination track found..." lines, which is strange. So far closest thing for fixing my problem is this command:
```
MP4Box -force-cat -add Awards\ -\ Recognitions\ Screens\ Video.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat Cornaro\ USLUGE\ video1.mp4 -cat DIOCLETIANS_BREAKFAST.mp4 -cat FLAVOURS_OF_DALMATIA.mp4 -cat Prognoza.mp4 -cat Restaurants\ -\ Bars\ 2016.mp4 -cat WineHappyHour3.mp4 out.mp4
```
but it is showing second video (Cornaro USLUGE video1.mp4) two times in row and then rest is normal. I am really out of idea what to do. Any help will be appreciated.

How can I convert/dump an animated SVG to MP4?
MP4Client seems not to support dumping to MP4 and MP4Box does not seem to allow specification of the duration to dump.
Is there any better way than to encode the raw AVI from MP4Client?
Can MP4Client dump to STDOUT for piping?
Using the simple SVG from #528, I tried using a fifo but both mencoder and ffmpeg yield a "running" image with changing color (even for other sizes like 101x1000):
```
MP4Client -no-audio -size 100x1000 -avi 0-10 -fps 25 all.dot.Make.asvg -out fifo.avi
ffmpeg -y -f rawvideo -pix_fmt bgr24 -r 25 -s 100x1000 -i fifo.avi file.mp4
mencoder -cache 8000 -nosound -o test.mp4 -ovc x264 -fps 25 -demuxer rawvideo -rawvideo w=100:h=1000:fps=25.000:format=bgr24 fifo.avi
```

Hi,
I have a problem, I started MP4Box as dash live server:
`MP4Box -dash-live 2000 -profile live -dynamic -segment-name seg_%s -mpd-refresh 4 -rap -out Glass_Half.mpd ../../Glass_Half_1080.mp4#video ../../Glass_Half_1080.mp4#audio ../../Glass_Half_720.mp4#video ../../Glass_Half_540.mp4#video -time-shift 600 -min-buffer 4000`
I used ffmpeg earlier on these files:
```
~/bin/ffmpeg -y -i CONTENT/Tears_Of_Steel/Tears_Of_Steel.mp4 -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 2400k -maxrate 4800k -bufsize 9600k -vf "scale=-1:1080" Tears_Of_Steel_1080.mp4
~/bin/ffmpeg -y -i CONTENT/Tears_Of_Steel/Tears_Of_Steel.mp4 -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 1200k -maxrate 2400k -bufsize 4800k -vf "scale=-1:720" Tears_Of_Steel_720.mp4
~/bin/ffmpeg -y -i CONTENT/Tears_Of_Steel/Tears_Of_Steel.mp4 -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 600k -maxrate 1200k -bufsize 2400k -vf "scale=-1:540" Tears_Of_Steel_540.mp4
```
After few iterations of server MP4Client start lagging, and after reset it (no server) audio is playing back slower then video and with time difference between audio and video is going larger.

I am referring to merge video tracks, audio and subtitles. (function -catx)
_mp4box.exe -mpeg4 -add video1.h265:xps_inband:noedit:trailing:name= -add audio1.aac:name= -add subtitle_all.ttxt:disable:name="No color, font, display flags in the LAVFilters" -catx "video2.h265 +audio2.aac" -catx "videoX.h265 +audioX.aac" output.mp4_
How to make time was counted relative to the video track and not on the longest track? Is there such a function?
http://i64.tinypic.com/2h4mjih.jpg
Interestingly, chapters no problem time.
Do all {:X} functions track -add need to save to the -catx?
Does function {:xps_inband} always changing codec with hvc1 to hev1?
Maybe a silly question. Is MP4Box supports crafted files h264/h265 Matroska?

Hello,
This is the first time i'm using GPAC, lastest version on Windows x86. The command line i have used is:
`mp4client.exe C:\60719414.mpd`
This is the error reported:
`[HTTP] Error parsing reply: Dialog Failure with remote peer for URL http://ss-dash.site.com:80/111/11111111/60719414.ism/QualityLevels(437668,id=NUM)/Fragments(video=i)?expire=NUM&path_depth=3&token=NUM

_depth=3&token=NUM = Dialog Failure with remote peer...Cannot open C:\60719414.mpd: Dialog Failure with remote peer`
The strange thing i see is **video=i**, is not wrong? I think it must be something like video=123456789? My only objective is use mp4client for see the video instead of the browser, if is possible and not violate any rules or copyright. Inside the MPD the info about the site that i have removed from this post

SMIL opacity animation was added to the SVG (see below, original output from graphiz), which works fine in firefox and SVGSalamander. MP4Client (v0.6.1, `MP4Client -size 100x1000 -avi 0-4 test.svg`) was the only tool I found to geneate a video of this anmiated SVG, i.e. rendering at constant time intervals. Testing translation in SVGs worked great but the opacity animation only seems to render values 0 and 1 but nothing in between.
Opacity is listed as supported property:
http://gpac.sourceforge.net/gpac_svg_support.xml#tiny_property_support
Are floating point values not supported or does the animated SVG need specific modification?
Many thanks for looking into this.

Hi,
I'm used MP4Box this way:
`MP4Box -dash 5000 -profile live -segment-name seg_%s -out Tears_Of_Steel.mpd ../../Tears_Of_Steel_800_crypted.mp4#video ../../Tears_Of_Steel_720_crypted.mp4#video ../../Tears_Of_Steel_480_crypted.mp4#video ../../Tears_Of_Steel_800_crypted.mp4#audio`
And I get mpd:

There is a little problem for me - videos are in two Adaptation Sets. Is there a possibility to get all Representations in one Adaptation Set? I want to have one AS with 3 representations of video, and second AS with one representation of audio

I'm encountering a strange issue that is certainly user error, but I can't find the cause. I have generated what should be a DASH-compatible file using FFmpeg, but when I run it through the MP4Box to segment the mp4 and generate the manifest, the resulting .mpd doesn't have an Initialization element in the AdaptationSet. The resulting manifest doesn't play in my test environment, but when I add the Initialization element manually then it works. What's particularly puzzling to me is that this used to work, and as I'm using the Debian-packaged version of gpac (with MP4Box version 0.5.1-DEV-rev5324) the application itself hasn't changed since the last time I did this successfully.
The above would indicate to me that there is some problem with the source file that results in MP4Box not seeing some expected data in the source file and that being the cause of the missing Initialization element, but I'm not sure what kind of data that would be, or why the file would magically work if I put the element in manually.
The specific command I'm using to generate the manifest is:
`MP4Box -dash 1000 -rap -frag-rap -profile onDemand -mpd-title test -out manifest.mpd transcoded.mp4`
If this is the wrong location for user help-type questions let me know, the sourceforge forums directed me here.

When provided input data of different duration (audio/video/subtitles), mp4box generates a DASH presentation with missing data. For example, using the sample data referenced below, the result is:
- 38 audio segments (152 nominal seconds of data)
- 43 audio segments (172 nominal seconds of data)
- 10 subtitle segments (40 nominal seconds of data)
With a period duration of 151.84 marked in the manifest.
~~While this behavior is OK in terms of video/audio - I do expect it to take the shortest duration, as that can fill all the representations with data and be conforming to DASH and, soon, CMAF - mp4box does not currently cover subtitles with acceptable behavior.~~
_Edit: behavior is also uneven with audio/video. None of the lengths are synchronized as expected. Note that the source material has uneven GOP sizes, which makes proper segmenting perhaps hard, so SegmentTemplate timing does not work out well. Still, the issue is demonstrated sufficiently by this test data._
Indeed, the same behavior would even not be appropriate to extend - it is normal not to have subtitles until the end! You have credits etc near the end, with no text samples. This is normal and extending the same behavior seen above would lead to undesired cutting.
Instead, my expectation is that mp4box generates empty subtitle segments to fill the subtitle track to the end. This is fairly trivial with WebVTT, at least, by including a single "empty cue" sample. With TTML, possibly it is also trivial? Though I wonder how it interacts with the different TTML-derived formats (EBU-TT versus IMSC1 and such).
mp4box version: gpac-0.6.2-DEV-rev517-gd4d3966-master-x64
Uploaded zip file with sample input data as "GitHub report: mp4box generates uneven representations" (uneven.zip).
Command to reproduce: mp4box -dash 4000 -profile "dashavc264:live" -out out\Manifest.mpd audio.mp4 video.mp4 subtitles.mp4
