I have recorded some .ts file which I now want to split, however I am getting output which I am not sure if I understand correctly.
Seems like the file is corrupted or something, which causes `-split` or `-splits` to fail. I assume any operation on that file would fail
Below is the output
```
mp4box -splits 1499000 video_to_split.ts
[MPEG-2 TS] PID 256 - same PTS 714557970 for two consecutive PES packets

Track 258 type: Metadata (ID3 ) - Program 1
Track 256 type: Video (H264) - Program 1

```
Is there any way to make it work?

GPAC installers will no longer work (specifically Mp4Box from the command prompt) on a clean install of Windows 10 Home Version 1903 OS build 18362.295 because msvcr100.dll is no longer supplied by GPAC installers and is not included in a clean Windows install.
Perhaps you could include Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package MFC Security Update (vcredist_x86.exe or vcredist_x64.exe) from https://www.microsoft.com/en-us/download/details.aspx?id=26999 to obtain msvcr100.dll like you supplied vc2015 to obtain vcruntime140.dll.

I imagine it is some script error. Please visit https://gpac.wp.imt.fr/downloads/; all links are dead. I used "Urgent" because I am not able to set a priority/severity level for this issue. Well, it is a showstopper of course.

Hi, I am using win10 and I test SRD with GPAC-0.8.0 and GPAC-0.6.2 in my PC. I have several questions about the [**MPEG-DASH SRD and HEVC tiling for VR videos**](https://gpac.wp.imt.fr/2016/05/25/srdtuto/).
1. I followed the example command:
> "MP4Box -dash 1000 [other dash params] source.mp4:desc_as=<SupplementalProperty schemeIdUri= \"urn:mpeg: dash :srd:2014\" value=\"0,0,1,1,1,2,2\"/>"
and set my own command as
> "MP4Box -dash 1000 -frag 1000 -rap - segment-name TileTest_ myOwnVideo.mp4:desc_as=<SupplementalProperty schemeIdUri= \"urn:mpeg: dash :srd:2014\" value=\"0,0,1,1,1,2,2\"/>"
. But in the terminal, I got error, which is "The syntax of the command is incorrect". I firstly test this function with GPAC-0.8.0 and then test this function with GPAC-0.6.2. And I got the same error.
2. In [**MPEG-DASH SRD and HEVC tiling for VR videos**](https://gpac.wp.imt.fr/2016/05/25/srdtuto/), I am not clear how the command
> indicates that source.mp4 is placed at X=0, Y=1 with width 1 and height 1 on a tiling grid of size 2×2.
3. Based on the paper, this work could help set different resolution for different tiles. I did not find any instrunction about SRD in the [MP4Box document](https://gpac.wp.imt.fr/mp4box/mp4box-documentation/)
Thank you very much.

Hi guys
I have managed dumping the files ( https://github.com/gpac/gpac/issues/1287) but with another dashing code:
MP4Box -dash 1000 -dash-profile onDemand -rap -frag 500 Jockey_256x144_100K_AVC.mp4 Jockey_320x180_200K_AVC.mp4 Jockey_384x216_240K_AVC.mp4 Jockey_384x216_375K_AVC.mp4 Jockey_512x288_550K_AVC.mp4 Jockey_640x360_750K_AVC.mp4 Jockey_768x432_1000K_AVC.mp4 Jockey_1024x576_1500K_AVC.mp4 Jockey_1280x720_3000K_AVC.mp4 Jockey_1280x720_3000K_AVC.mp4 Jockey_1920x1080_4300K_AVC.mp4 Jockey_1920x1080_5800K_AVC.mp4 -mpd-title AVC -out AVC_1s.mpd
and for the same for hevc, vp9 and av1, I replicate the above command accordingly.
I have a question
I noticed that the MP4Client does not adapt with AV1, although there is higher bandwidth available. Is there anyway I can apply to ensure the adaptation?
Hence, I played AVC, HEVC and VP9 mpds and they are all perfectly playable
Please find the gpac.cfg
[GPAC.txt](https://github.com/gpac/gpac/files/3481385/GPAC.txt)
With my thanks in anticipation

I'm posting as a new user on what seems to be a well maintained project and issue tracker.
- [X] I looked for a similar issue and couldn't find any.
- [X] I tried with the latest version of GPAC.
- [X] I give enough information for contributors to reproduce my issue
Using the latest nightly build on macOS 10.14.6.
```
$ /Applications/GPAC.app/Contents/MacOS/MP4Box -version
MP4Box - GPAC version 0.8.0-rev47-gbafe4cd3-master
(c) Telecom ParisTech 2000-2018 - Licence LGPL v2
GPAC Configuration: --extra-cflags=-Wno-deprecated
Features: GPAC_64_BITS GPAC_HAS_SSL GPAC_HAS_SPIDERMONKEY GPAC_HAS_JPEG GPAC_HAS_PNG
```
I am experiencing issues with *some* (and always the same) videos on an iPod Nano:
**Problem 1**. Specifically around 12 or 45 minutes into the video, the built-in video player either:
- exits back to the video list
- runs amok playing video at several minutes per second
**Problem 2**. White noise artifacts, usually the left channel, in the same places per video.
What I'm doing (using latest FFmpeg):
`ffmpeg -i original.mp4 -ar 44100 -ac 2 -b:a 128k -profile:v baseline -level 3.0 -pix_fmt yuv420p ffmpeg.mov`
Then:
`MP4Box -add ffmpeg.mov ipod.mov` resolves problem 1, but then there is no audio on the iPod (though there is audio with ffplay, vlc, etc.)
`MP4Box -ipod ffmpeg.mov ipod.mov` brings back the audio, but alas also the original problem 1.
Workaround for problem 1: Convert video to AVI and back to MP4 (using FFmpeg). The problem may thus revolve around container metadata retained during mp4-mp4 operations.
However, doing diffs on `ffprobe -show_streams` or `MP4Box -info` before and after the AVI workaround reveals no relevant change in metadata.
For problem 2, I have found no workaround. I assume MP4 videos must have AAC audio. I've tried both standard aac and libfdk (the latter may produce slightly less noise).
If there is interest in resolving the problem, I can share small example files and any other required information. Maybe someone on the dev team as an iPod Nano to test this on?
FYI: Targeting iPod, ie. `ffmpeg ... -f ipod ... ffmpeg.m4v`, has no effect on the problem.

Mp4box provides `pssh` parameter to specify where cenc protection data are supposed to be placed. This parameter is working fine in master branch, however, filters branch is either ignoring the values or printing error `Wrong argument value moof for unsigned int arg pssh enum v|f|mv|mf|m|n - using 0`
For instance using `-pssh=mv` no error is printed, but pssh data are missing in the mpd manifest, they are only in init segments.
Using `-pssh=m` prints the above mentioned error and again, pssh data are obviously missing in the manifest, but this time they are wrongly present in init segments.
Similar unexpected behavior can be observed with the rest of pssh values as well, they all seem to default to `-pssh=v`.
Seen with 0.9.0-DEV-rev2670-g88c73eb3-filters.

It seems that packaging a TRUEHD/MLP stream into a mp4 container isn't supported by any currently available software - despite the capabilities of the MP4 container.
References:
http://mp4ra.org/#/codecs - see codec mlpa - (clearly states support for Dolby MLP)
https://developer.dolby.com/globalassets/technology/dolby-truehd/dolbytruehdbitstreamswithintheisobasemediafileformat.pdf - describes the storage of Dolby® TrueHD (MLP) audio bitstreams in a file format compliant with the ISO base media file format
https://en.wikipedia.org/wiki/Comparison_of_video_container_formats - see audio coding formats support - also clearly states support for TRUEHD in mp4.

When whitespace is present on `div` level (see [whitespace_below_div.xml.log](https://github.com/gpac/gpac/files/3444159/whitespace_below_div.xml.log); remove `.log`), messages are shown that the namespace should be checked:
```
[TTML] ignored "
" node, check your namespaces
[TTML] ignored "
" node, check your namespaces
```
Used cmdline: `MP4Box -add whitespace_below_div.xml:ext=ttml test.mp4`
However the reason is that on `div` level just text nodes (consisting of spaces) are found, as the file contains indentation. As these text nodes are already ignored on `body` level, the same should be done on `div` level, in order to prevent such false positives - as actual text content can only be present on `p` or `span` level anyway.

Hello guys
I used to dump easily the segments while streaming for post streaming tests. However, now I only can find the mpd file and the text file that contains the mpd details on the temp folder (where i directed the streaming to be stored).
If i use the MP4Client to stream each segment (NOT requesting the MPD), I can get these streamed files in the directory, but I get them in one mp4 file not multi mp4 files
I checked the configuration in https://github.com/gpac/gpac/issues/2 , but they are not working with me!

[The video ](https://drive.google.com/open?id=1M8gJMd_-OhX6qJD5KTxBHkavU64w-_WY) was being HLS streamed using AES-128. Even though I could view it perfectly fine in the browser, VLC doesn't play the downloaded video file. It doesn't seem to contain any metadata or codec information either.
I thought re-encoding it with ffmpeg might solve the issue. But ffmpeg throws these exceptions irrespective of the operation I try to perform:
`[mov,mp4,m4a,3gp,3g2,mj2 @ 000002a477298a80] Format mov,mp4,m4a,3gp,3g2,mj2 detected only with low score of 1, misdetection possible!
[mov,mp4,m4a,3gp,3g2,mj2 @ 000002a477298a80] moov atom not found

Google search led me to mp4box. But running `MP4Box -add 4.mp4 41.mp4`, `MP4Box -inter 0 4.mp4` or `MP4Box -add 4.h265 41.mp4` show exceptions such as:
- Incomplete MDAT while file is not read-only

For example when splitting Opus MP4s, we should add an option to add overlapping samples. At the moment we only split the samples, so the splitted content rendered in a playlist would contain some gaps.

I am looking for a way to get the sample number's of the previous and next random access points for a given sample. I looked at `gf_isom_get_sample_for_media_time` using `GF_ISOM_SEARCH_SYNC_FORWARD` and `GF_ISOM_SEARCH_SYNC_BACKWARD`, but it does more work than I want because I don't actually need the sample data.
The function `stbl_GetSampleRAP` does exactly what I want, but it is not exported.
Is there any way to achieve what I want using public API, or if not, is there any chance that such functionality could be exposed in public API?

I'm experiencing a huge difference in perfomance of mp4box between filters and master branches when dashing.
For the test I used a 288p 5-minute video as source. It does not seem like fine-tuning arguments play any role in performance nor what kind of content is being processed, so the comparison here is made with simple commandline `mp4box -dash 2000 source.mp4#video -out manifest.mpd`
Windows build 0.8.0-rev18-gb2e67a99-master is able to dash such content in 1.5 second on an Intel i5@2,5Ghz CPU with SSD.
Windows build 0.9.0-DEV-rev2567-g2fb6b79d-filters requires whopping 34 seconds to finish on the same system.

Hello,
I tried compiling GPAC and I got MP4Box installed after following the instructions here : https://gpac.wp.imt.fr/2011/04/20/compiling-gpac-on-ubuntu/
I am able to use MP4Box but not gpac. How do I use the gpac binary? How do I build and get it?
I am trying to follow https://github.com/gpac/gpac/wiki/pipes on using gpac for pipes.
How to compile the gpac executable on my system so that I can try out gpac for pipes?
Thanks

If dashing encrypted multichannel 5.1 audio with 0.8.0-rev1-gc1990d5c-master and older revisions, resulting dash manifest claims that there are just two channels.
`<AudioChannelConfiguration schemeIdUri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="2"/>` even though `mp4box -info aac51encrypted.mp4` correctly reports all 6 channels.
If dashing unencrypted 5.1 audio, channels are declared correctly as
`<AudioChannelConfiguration schemeIdUri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="6"/>`
This is already corrected in the new 0.9.0 filters branch, but can it please be backported also into 0.8.0 master branch that is as of now more stable and in some procedures much faster?
Circumstances surrounding channel detection in this scenario don't seem to be related to recent fix in https://github.com/gpac/gpac/issues/881 for GPAC 0.9.0.
I've uploaded clear and encrypted multichannel test content to your MediaFire storage for you to verify as multichannel.zip.

Using `mp4box -crypt crypt.xml input.mp4 -out output.mp4` works fine in GPAC 0.7.2, however, 0.9.0-DEV-rev2522-ge29dba15-filters is unable to encrypt any H.264 or HEVC content I tried using the same crypt.xml based on AES-CTR. VP9 is ok, haven't tested AV1.
Alternative approach with `gpac -i input.mp4 cecrypt:cfile=crypt.xml @ -o output.mp4` yields the same error with H.264 or HEVC content as mp4box itself.
`ISOBMF: Error Bad Parameter writing box senc`
`[iso file] Box trak wrote 12731 bytes but size is 24731`
`ISOBMF: Error Bad Parameter writing box trak`
`[iso file] Box moov wrote 12847 bytes but size is 25530`
`[MP4Mux] Failed to write file: Bad Parameter`
I can provide crypt.xml upon request.

When str is full without '\x00', strdup will make a heap overflow.

Compiling and running mp4box.exe from the filters branch even without any arguments creates `$workdir/Storage/, $workdir/GPAC.cfg` folder and file.
I did have some problems with compiling in MSYS2+MingGW due to a new dependency on libavformat.h ffmpeg files. I am using the isolated msys2 console for compiling so had to do some manual copypaste header+lib files from the ffmpeg project.
I am missing some enable/disable flags? I don't think mp4box should create a folder and cfg file?

I skipped GPAC 0.8.0 evaluation, so it might have been introduced there, but I see that GPAC 0.9.0 is newly paying closer attention to `sgpd` and `sbgp` box and info about roll distance, i.e. audio decoder delay. If grouping type is set to `roll` in those boxes, mp4box when dashing prints `[Dasher] WARNING! Max SAP type 4 detected - switching to FULL profile`.
Representation element for audio track in the mpd manifest then changes value to 4 for `startWithSAP` attribute and bigger issue is that the profile is truly set to full, which may cause possible incompatibility with some user agents, e.g. with TVs due to their strict implementations.
Mp4 content with an audio track muxed by FFmpeg is using these `sgpd` and `sbgp` boxes with grouping type set to `roll`, so you can imagine that upgrading to 0.9.0 as is would likely break many current workflows based on FFmpeg -> mp4box chain that rely for example on live profile in their dash streams and use the source mp4 without demuxing to raw bitstreams.
I uploaded a test file to your Mediafire share as roll_distance.mp4 that exhibits this when dashed.
I assume the specification is clear in this regard and the new behavior adheres to it, but is it truly that strict? Older GPAC versions have no issues with such content and the resulting dash stream is always correctly in sync between audio and video even if specifying desired live or onDemand profile.
Mp4 files missing `sgpd` and `sbgp` boxes altogether are not affected by this at all. Unlikely to do it without them in FFmpeg, though (remotely related to https://github.com/gpac/gpac/issues/1253 ) .
Thank you in advance for your comments.

The simplest command to reproduce this `gpac -i test.mp4 -o c:\test\test.mpd` results in
`No filter chain found for PID PID1 in filter dasher to any loaded filters - NOT CONNECTED`
The process now hangs, stopping with CTRL+C shows possilbe reason as badly interpreting `:` after drive letter
`Unknown argument ":\test\test.mpd" set but not used by any filter - no matching argument found`
Relative paths without drive letter work as expected. Tested with 0.9.0-DEV-rev2428-gfb72027b-filters.

Testing the "filters" branch with 0.9.0-DEV-rev2428-gfb72027b-filters build on Windows 10 revealed possible issue with the way ANSI escape sequences are processed.
The sequences are handled as plain text and corrupt the output.
I tried older and newer Windows 10 revisions between 1607 to 1809 in order to eliminate the possibility of system error as support for this was missing at Windows 10 launch and was added in 1511, but result is always the same for both cmd and powershell.

I have created an mp4 file (with ffmpeg) that contains chapters in iTunes format: https://test.michael-kaufmann.ch/test.mp4
mp4box does not know the box type "text", but apart from that, everything seems to work:
```
mp4box.exe -new -add test.mp4 test2.mp4
[iso file] Unknown box type text in parent gmhd
[iso file] Unknown box type text in parent gmhd
IsoMedia import test.mp4 - track ID 1 - Video (size 640 x 480)
[iso file] Unknown box type text in parent gmhd
IsoMedia import test.mp4 - track ID 2 - Audio (SR 48000 - 2 channels)
[iso file] Unknown box type text in parent gmhd
IsoMedia import test.mp4 - track ID 3 - media type "text:text"
Saving test2.mp4: 0.500 secs Interleaving
```
When processing the file that has just been created for a second time, a new warning about extra bytes appears:
```
mp4box.exe -new -add test2.mp4 test3.mp4
[iso file] Unknown box type text in parent gmhd
[iso file] Box "text" (start 5360) has 20 extra bytes
[iso file] Unknown box type text in parent gmhd
[iso file] Box "text" (start 5360) has 20 extra bytes
IsoMedia import test2.mp4 - track ID 1 - Video (size 640 x 480)
[iso file] Unknown box type text in parent gmhd
[iso file] Box "text" (start 5360) has 20 extra bytes
IsoMedia import test2.mp4 - track ID 2 - Audio (SR 48000 - 2 channels)
[iso file] Unknown box type text in parent gmhd
[iso file] Box "text" (start 5360) has 20 extra bytes
IsoMedia import test2.mp4 - track ID 3 - media type "text:text"
Saving test3.mp4: 0.500 secs Interleaving
```
So probably there is a bug and mp4box adds some extra bytes when writing unknown boxes.
I have used this nightly build for testing: https://download.tsi.telecom-paristech.fr/gpac/new_builds/win32/gpac-0.7.2-DEV-rev1172-gc23d54ed-master-win32.exe

Hello there
I have dashed my produced representations with different segment sizes using the MP4Box.
I noticed that when I play the segment size=1sec (using the MP4Client), the quality switching occurs after almost 8-10 seconds! and this degrades the overall of the QoE.
My question is that:
Is there anyway I can push the configurations to increase the quality of representations immediately?
Hence, the available bandwidth is higher than the highest quality's bitrate with no less than 5folds of the bitrate.
One of the expected answers I may get is that to change the StartRepresntation to be =MaxQuality. If I do so, then I gain the highest quality but when I enforce very low bandwidth, I get a stalling for the video and the video playback gets interrupted!!
I look forward to hearing back from you guys
Regards,
Irrz

Hello!
I'm interested in using MP4Box to decrypt CBCS encrypted fMP4 files. According to the built-in help, the tool only supports CTR:
```$ mp4box -h crypt
ISMA Encryption/Decryption Options
-crypt drm_file crypts a specific track using ISMA AES CTR 128
-decrypt [drm_file] decrypts a specific track using ISMA AES CTR 128
* Note: drm_file can be omitted if keys are in file
-set-kms kms_uri changes KMS location for all tracks or a given one.
* to address a track, use 'tkID=kms_uri'
```
However, I see some issues in git related to CBCS, so I think it DOES support it (maybe some documentation needs to be updated - which I'd be happy to submit a patch for once I know how to do this ;))
Assuming I have an fMP4 file encrypted with CBCS per FairPlay Streaming, and I have the KID, IV, and CEK, how do I tell MP4Box to decrypt it into clear fMP4?
- [x ] I looked for a similar issue and couldn't find any.
- [ 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 ...).

(mp4box from github trunk)
I use the same drm settings for video and audio streams. Audio segments have sgpd+sbgp samplegroup atoms. Video segments does not have.
Video segment is `/styp, /moof/traf/tfhd|tfdt|saiz|saio|trun|senc, /mdat` atoms.
Audio segment is `/styp, /moof/traf/tfhd|tfdt|sgpd|sbgp|saiz|saio|trun|senc, /mdat` atoms.
I did a script to remove sgpd+sbgp atoms and fixed trun.dataoffset value in segments accordingly. Dash stream is still played fine on my test devices.
Is there a reason why audio segments have sgpd+sbgp atoms? I think video segment is an expected behaviour no atoms written because my drm settings are global? Bug or possible to control with a command-line argument?

Hello
First of all, thank you for great tool :)
I'm wondering if such a scenario is possible.
I'm recording 5 seconds long videos on Android device as mp4 files. After each video is recorded it is sent via web sockets to my server (byte array). On that server, I would like to actively wait for those chunks of the video. When they arrive on my server I have to create dash content from them to have m4s files and allow my web client to consume those files. What is puzzling me the most is if GPAC is able to notice that those mp4 files are in fact the same video.
Any bits of advice/suggestions will be appreciated.
Regards

Hello,
I want to build a live streaming system for 4K VR video with DASH SRD.
I can use the nginx-rtmp server to build a live streaming server with DASH, and I know MP4Box is able to generate tile-based MPD file for a static video.
Does MP4Box or any other software support to generate an MPD file for HEVC tile-based live streaming?
thanks

Hi,
I uploaded an init segment for HEVC/HDR10 on MediaFire (name: 175_video_cmaf_2_init.mp4) which is reported as using hvc1.1.6.L21 as video codec by MP4box, while it's actually using hvc1.2.4.L150.B0 as shown in the attached screenshot from MP4box.js.
If someone can check what's going on there, that would be great. Thanks !

Hi, and thanks for your project.
## How to reproduce
The AAC is a 40mo french podcast, here we mux with and without chapters :
```bash
$ wget https://drive.google.com/uc?export=download\&id=1oLQ75ddUgjUt2uOlKQKZUl9eDpmBZ7GO -O s01e01.aac
$ wget https://drive.google.com/uc?export=download\&id=1xgRG_cy13qOYMbA0t8mHPruGm6vPANJZ -O s01e01.ttxt
$ MP4Box -add s01e01.aac#audio s01e01_nochap.m4a
$ MP4Box -add s01e01.aac#audio -add s01e01.ttxt:chap s01e01_chap.m4a
```
## Issue
I've been, truggeling with a simple chapter file, in a straightforward M4A output.
The given AAC is a `58'15` length file.
And I want to add this chapter file :
```xml
<!-- (...) -->
<TextSample sampleTime="00:00:00.000">Intro</TextSample>
<TextSample sampleTime="00:02:35.000">Impose ton style - Le Trou</TextSample>
<TextSample sampleTime="00:14:20.000">Impose ton style - L'Évadé d'Alcatraz</TextSample>
<TextSample sampleTime="00:25:17.000">Impose ton style - Les Poings contre les murs</TextSample>
<TextSample sampleTime="00:41:03.000">Quartier libre</TextSample>
<TextSample sampleTime="00:48:44.000">Le Jeu</TextSample>
<TextSample sampleTime="00:55:43.000">Outro</TextSample>
<!-- (...) -->
```
The `nochap` file is muxed nicely into a `58'15` length M4A.
The `chap` one outputs a weird `1'02'42` M4A file, with a buggy end.
(obviously : no audio in the last minutes).
I tried with many players (Quicktime, Podcast Addict, VLC), same result.
And... the last chapter seems skipped in the output file.
Weird results in my tests :
- If I remove any chapter in the file, everything's fine. The bug seems to appear if there is a 6th one.
- Removing accentuated chars doesn't change anything.
- If I change the timestamp of the last chapter, I have another total-length, without consistency.
## Environment
System : `MacOS 10.14.4 (18E226)`
MP4Box : `0.7.2-DEV-rev1092-g9991b44c-master` (Downloaded from the given nightly builds)
I already seen a few "chapters" bug reports, but on other specific cases :
- Merging tracks, not this case.
- Problem with milliseconds, not this case either : all my milliseconds are 000.
I'll take any hint.
Thanks, and cheers from France.

Hi
We've been trying to dash a file set containing 1 video, several audios & a subtitle file. Without the subtitle file everything works fine. Adding the subtitle makes everything hang. There is no error of progress report. The video & audios are generated using ffmpeg, the subtitles are coming out of ccextractor. We've tried various formats, all seem valid, but the result is always the same, namely mp4box hangs.
The command line I am using is –
mp4box -dash 5000 -frag 2000 -rap -profile dashavc264:onDemand -mpd-title Example-Title -out output101.mpd subtitle1.mp4:role=subtitle
Any help is much appreciated

Dear all,
Thanks a lot for the discussion here to help me moving forward in my projects.
I am wondering in how the Bandwidth works in MP4Box? here are the tests I made an my Android phone (Samsung S9+):
with ffmpeg and MP4Box, I generated 3 different resolutions video clips (960px*960px, 1440px*1440px, 2160px*2160px) and MP4Box them into mpd files. here is the command MP4Box -dash 2000 -frag 2000 -rap -frag-rap -profile live filename
However, on my Android phone I can only play the medium resolution (1440px) video even the higher bandwidth is available.
I did another test with 2160px and 2560px resolutions in a mpd file, then 2160px streaming video can be fluently played with the same player on Android.
So i was wondering how the bandwidth is working regarding to resolution?
Or it might be a player related issue ?
thanks a lot for your helps

Hi,
For a test case of my own program, I generated an elementary stream containing SPS/PPS bytes then the same I frame data over and over. When I try to use mp4box to wrap the .264 file to a MP4 file, I get "AVC Import results: 1 samples (126 NALUs) - Slices: 124 I 0 P 0 B - 0 SEI - 124 IDR", resulting in a single frame file.
Compare files produced by "MP4Box -add sample.264 -new sample-mp4box.mp4" and "ffmpeg -i sample.264 sample-ffmpeg.mp4"
For reference, I used ffmpeg smptehdbars input to generate a .264 file and extract the test case data. See [sample.zip](https://github.com/gpac/gpac/files/3100528/sample.zip)
If you generate a sample file using "ffmpeg -f lavfi -i smptehdbars=300x200 -t 4 -r 25 -force_key_frames "expr:1" test.264", you'll see I-frames are interleaved with SPS/PPS data blocks. I'm not aware of such constraint but the H.264 format is so complex I may have missed some rules.
Anyway, thanks for you work, it's really helpful for us.

Hi there
I have produced various video contents and now I can play them perfectly with MP4Client.
I am wondering if there is a way I can save all the streams in one mp4 file or any file types?
Hence, I read the issues in #2 and #11 but they are refferening to reading from the saved segments, whereas I want to save all segments in one playable file
Many thanks

Hi, I am using a third party packager that creates DASH manifests from the mp4 stream that is created by MP4Box. I am using x264/x265 to produce a raw h264/hevc stream which gets packaged by MP4Box, these streams have repeated headers. Accordingly, I am using the xps_inband tag to create a avc3/hev1 MP4 stream which I can confirm have repeated headers in the media data. This means unlike avc1 and hvc1, the VPS/SPS/PPS are missing from the avcC and hvcC box. This is causing the third party packager to behave unpredictably. I would like to retain the SPS/VPS/PPS in the configuration boxes besides it being in the stream. Can you please point to the particular code where I can make changes after forking the project for my particular use case.
This is a sample command I am using
mp4box -add raw_stream.hevc:xps_inband -new output.mp4
Thanks

Is there any existing feature to enable SPS and PPS to be added to avc Config

Hello there
I have encoded raw video using the ffmpeg tool, I used the libvpx-vp9 and the container used was .webm. then, i transcode it using the ffmpeg -i file.webm -c:v copy out.mp4. and then dashed it using the mp4box.
the issue is that I cannot play it back using the mp4client as it can be seen in the attached photo.
Hence, I can play it in the THEOplayer website perfectly.

Hi There,
Currently I am trying to combine/concatenate specific MPEG-DASH video segments(m4s ex:int.mp4, seg_1.m4s, seg3,m4s,sge5.m4s) into one mp4 file. [example](https://i.stack.imgur.com/ve5Bu.jpg) .This question is also asked in [here](https://stackoverflow.com/questions/55701262/combine-specific-mpeg-dash-segments-ex-int-mp4-seg-1-m4s-seg-3-m4s-into-one)
I have used this command which works perfectly while combining all the m4s segments, but when I am trying to use specific segments then there is a problem.
cat init.mp4 $(ls -vx seg_*.m4s) > source.mp4
cat init.mp4 > source.mp4
cat segment-1.m4s >> source.mp4
cat segment-3.m4s >> source.mp4
cat segment-5.m4s >> source.mp4
I will be glad for any help or direction to solve this problem.

Thanks everyone here to improve MP4box,
Recently we had an strange issue while play mpd file in our mobile VR (android system with Exoplayer).
We have tested with the demo of SDK, comes with a .mpd file on google cloud storage:
https://storage.googleapis.com/daydream-deveng.appspot.com/japan360/dash/japan_day06_eagle2_shot0005-2880px_40000kbps.mpd
With this URL, we can successfully play .mpd file with VR rendering.
However, when we tried to generate our mp4 to mpd with mp4box, the generated mpd file can be played by MediaPlayer (e.g. IINA), but not on Android system.
We would like to ask the question here just make sure our generated .mpd is correct, here is the link:
http://18.185.102.182/ClassroomTest1/Scene_1_dash.mpd
With the same Exoplayer, we can play demo mpd files from google storage but not ours. However, both mpd files can be played via local MediaPlayer.
We were using :https://github.com/Cloudoki/mp4-to-mpegdash script to convert our mp4 to mpd manifest. file.
thanks everyone

I'm sorry if this is a sort of a trivial question but I fail to actually understand what BS tags are for. maybe it's because I don't have a good enough knowledge about MSE and I'm a newcomer in these stuff.
I read the [nhml docs](https://gpac.wp.imt.fr/mp4box/media-import/nhml-format/) and also the [common encryption docs](https://gpac.wp.imt.fr/mp4box/encryption/common-encryption/) but I still fail to really understand the format. I would really appreciate it if you could be so kind as to break down and compare these three xml files:

Is there any reason why one might not only encrypt RAPs for a movie? I can understand that in some types of videos for example a video with some critical text encrypting only the RAPs would not be enough but what about for a movie. is there any disadvantage?
Also I don't understand why the first one doesn't have the key in the DRMInfo tag.
By The Way, Here is the xml I tried to make myself but it doesn't work:
```
<?xml version="1.0" encoding="UTF-8" ?>
<GPACDRM type="CENC AES-CTR">
<DRMInfo type="pssh" version="1">
<BS ID128="1077efecc0b24d02ace33c1e52e2fb4b"/>

</DRMInfo>
<CrypTrack trackID="1" IsEncrypted="1" IV_size="8" first_IV="0x603f39bfdb3d9799" saiSavedBox="senc" selectiveType="RAP">
<key KID="0xcd7eb9ff88f34caeb06185b00024e4c2" value="0x63cb5f7184dd4b689a5c5ff11ee6a328"/>
</CrypTrack>
</GPACDRM>
```
Also I read in the docs:
> trackID : specifies the track ID to encrypt. If not set, this crypt configuration applies to all tracks for which no CryptTrack with a trackID is specified.
So I expect to get moth audio and video tracks encrypted if I don't specify trackID but if I don't specify it nothing happens. So I just duplicate the `CrypTrack` tag, one with trackID="1" and the other with trackID="2" is that the right way of encrypting both tracks with the same key?

Hello,
I am trying to implement a tile-based DASH streaming, where a client can adapt bitrates for each tile in the frame.
In order to achieve the goal, I want to obtain each tiles in video with different bitrates, for example
tile_1_1Mbps.mp4
tile_1_2Mbps.mp4
...
tile_2_1Mbps.mp4
tile_2_2Mbps.mp4
...
However, using ffmpeg I cannot encode each tracks,
("ffmpeg could not find codec parameters" error shows up...guess maybe the problem comes from the fact that each tile.mp4 has hvc2 format, which ffmpeg does not support?)
and encoding the whole video in a bitrate and dividing to tracks results in each tile bitrate different from the designated bitrate.
Could someone help with the issue?
Thanks in advance

Hello, following the tutorials provided, I have successfully managed to encode the video into tiles with HEVC, split each tiles as separate .mp4 files, and merge them back into a single .mp4 file.
Moving forward, my goal is to implement a tile-based DASH video streaming, where a client requests only some number of tiles (not the full frame).
For start, I DASHed the video divided into 2x2 tiles and got the following files:
init.mp4 (containing 1+2*2 tracks)
track1_init.mp4 (containing 1 track)
track2_init.mp4
...
track5_init.mp4
track1_bitrate1_segment1.m4s
...
track1_bitranteN_segment1.m4s
track2_bitrate1_segment1.m4s
...
track2_bitrateN_segment1.m4s
...
My question is, how can I merge different tile segments back into a single segment, that can be playbacked in the client?
In case of .mp4 files without DASH, all I had to do was merge different tracks with the commands like
MP4Box -add Q2.mp4#6 -ref 4:tbas:1 -ref 1:sabt:4 Q1.mp4
However, in case of DASH, I have no idea which files I should merge (init.mp4, track1_init.mp4, track1_bitrate1_segment1.m4s, ...etc.)
I would really appreciate if someone could tell me the solution.
Thanks very much in advance.

Hello,
I tried tile-based HEVC encoding, following the tutorial provided.
https://gpac.wp.imt.fr/2017/02/01/hevc-tile-based-adaptation-guide/
I obtained the tiled video with the command
MP4Box -add video_tiled.hvc:split_tiles -fps 30 -new video_tiled.mp4,
and also checked with the command
MP4Box -info video_tiled.mp4
to see that the file has 1+MxN tracks.
I also cheked that
MP4Box -rem 3 video_tiled.mp4 -out test_tile_lost.mp4
successfully removes some tiles, with no problem playing the video with MP4Client.
However, in all of the above steps the tiles (or tracks) are contained in a single .mp4 file.
What I want to implement is a tile-based HEVC 360 DASH video streaming, where a client requests only some tiles (rather than a full frame), merges it back to a frame and render it on screen.
Could you guide me on the steps to do the following?
1. Save each tile into separate files (e.g., maybe into video_track1.mp4, video_track2.mp4 ... etc.?)
2. Create a DASH server with the separated tiles, encoded multiple times in different bitrates
(e.g., maybe into segment1_track1_bitrate1.m4s, segment1_track1_bitrate2.m4s, segment1_track2_bitrate1.m4s, segment1_track2_bitrate2.m4s, ... etc. ?)
3. Merge the tiles back into a single video stream that can be decoded and played
I would really appreciate it if someone could point me to some related issues opened that I might have missed, or some example codes that can achieve my goal.
Thank you in advance!

using this mpd the playback of first period is fine but it fails to switch to other period .
- [ yes ] I looked for a similar issue but it was for mp4 ,with the same command as mentioned above i have generated stream for mp4 dash content it works fine .

I want to convert some h264 mp4 videos to clearkey encrypted dash. For now I want to serve them on localhost. So I don't have bandwidth limitations. There are a few things I'm confused about. I'm assuming I should use dashavc264:onDemand profile with static mpd since my videos are not live and they are offline.
1. How should I decide what segment duration I should use? does it depend on how often I have keyframes in my video? how does it affect seeking/trickplay performance? Does it affect anything else?
2. Since I'm using onDemand profile, where each media presentation is a single segment, should I have subsegments for my single subsegment of each segment? What is the use of setting subsegments for my single subsegment of each segment? How does the duration affect other things?
3. Why would I not force my segments to begin with random access points?
4. what about my fragments?
If I understood correctly random access points are my iframes. my intuition tells me that segments should always start with I-frames. I think I don't really understand the correct meaning and purpose of segments and subsegments. Are they simply random cuts in the media stream so as to split it into chunks? What is the difference between a segment, a subsegment, and a subsegment of a subsegment.
5. Should I use segment-timeline?
6. Should I add a box of type \’MARK\’ at the end of each DASH segment.
7. What min buffer time should I use?
8. what is the advantage of storing PSSH boxes in first moof of each segment instead of in movie box?
Thank you in advance for any help you might be willing to give.

Using the current release of gpac/mp4box via cmd on a Win 10 machine.
I have several mp4 videos where the Audio Language is **und** or otherwise marked as unspecified. The audio track is primarily English but there are scenes in a foreign language for which I need subtitles inserted. I use Emby to play the media and it has a Smart subtitle setting that inserts subs into only non-English scenes but to do that the Audio Language needs to be set to English. **mp4box -lang en-US file.mp4** creates a 480p copy of the 1080p file. I thought I had read somewhere that **-lang** would just overwrite the original audio tag but that's not happening, and I'd be ok with a new file if it was the same quality as the original.
I've searched a good bit for this issue before posting so if I missed a discussion please direct me to it. TIA.

Can MP4client change the quality of each tile (select the representation of each tile) based on the viewport. If so how we determine the viewport? By moving around in the gui?
Following you see how I am generating the tile-based video which I wanna play locally (so no discussion on bandwidth):
kvazaar -i Dance_Left_1920x960.yuv --input-res 1920x960 -o Dance_Left_1920x960_rep1.hvc --tiles 3x3 --slices tiles --mv-constraint frametilemargin -q 22 --input-fps 30
kvazaar -i Dance_Left_1920x960.yuv --input-res 1920x960 -o Dance_Left_1920x960_rep2.hvc --tiles 3x3 --slices tiles --mv-constraint frametilemargin -q 37 --input-fps 30
MP4Box -add Dance_Left_1920x960_rep1.hvc:split_tiles -fps 30 -new Dance_Left_1920x960_rep1.mp4
MP4Box -add Dance_Left_1920x960_rep2.hvc:split_tiles -fps 30 -new Dance_Left_1920x960_rep2.mp4
MP4Box -dash 1000 -profile live -out Dance_Left_1920x960.mpd Dance_Left_1920x960_rep1.mp4 Dance_Left_1920x960_rep2.mp4
Now when I am playing this mpd by MP4client always representation 2 is chosen for all tiles and all segments (which is the representation with the lower bitrate)
And if MP4client cannot detect the viewport how can I force it to select specific representations for each tile?
Thanks,
|
How does MP4client choose representations when playing from a local storage for a hevc-coded tile-based stream which uses SRD?

---------------------------------------------------------------------------------------
Hi. I'm doing a college job and would like to play only one tile from a 360° HEVC tiled video, but MP4Client show several errors.
After following the instructions at https://gpac.wp.imt.fr/2017/02/01/hevc-tile-based-adaptation-guide/ to produce a tiled HEVC video I would like to play only one tile.
I codify the video using
`kvazaar --input video.yuv --input-res 4320x2160 --input-fps 30 -p 30 --tiles 3x3 --slices tiles --mv-constraint frametilemargin --bitrate 3000000 --output video.hevc`
so I add in a MP4 file using MP4Box:
`MP4Box -add video.hevc: split_tiles -new video.mp4`
The video.mp4 file plays perfectly using
`MP4Client video.mp4`
However, when I extract a track using
`MP4Box -raw TrackID video_tiled.mp4`
All .hvc files fails. Only track 2 appears an image, but it does not play. All other tracks fail and display the message:
> $ MP4Client video_track3.hvc
> Using config file in /home/henrique/.gpac directory

So, I removed the unwanted tiles using the _-rem_ option. For example to leave only track 2 (tile 1) I use
`MP4Box -rem 3 -rem 4 -rem 5 -rem 6 -rem 7 -rem 8 -rem 9 -rem 10 video.mp4 -out video_2.mp4`
But this works correctly for track 2 only. When I use this for other tracks like this:
`MP4Box -rem 2 -rem 4 -rem 5 -rem 6 -rem 7 -rem 8 -rem 9 -rem 10 video.mp4 -out video_3.mp4`
The MP4Client fails and displays the error:
> $ MP4Client video_3.mp4

Is it really possible to play only one tile?
I'm using Ubuntu 18.04.2 and GPAC version 0.7.2-DEV-rev1018-g0ab801f8b-master and Kvazaar v1.2.0-244-ga13fc510 2019-02-04.
Later, I also installed an external OpenHEVC in Gepac build using this instructions (https://github.com/gpac/gpac/issues/979) and there was no result.
Thanks.

Hi,
I'd like to use the gpac library for a project of my own.
Packages provided by Debian (buster) and Ubuntu (18.10) are too old for me so I have to compile it from source.
The first issue is that https://gpac.wp.imt.fr/2011/04/20/compiling-gpac-on-ubuntu/ guide is old and there are some packages that are gone now. OpenJPEG development library is not detected even if I install libopenjp2-7-dev which seems the right packet.
Anyway, this not blocking for me.
Another issue is that [/usr/local/]include/gpac/configuration.h file produces "error: #error "Unknown target platform used with static configuration file" when used. I manually replaced it with config.h generated file from the source directory and now it works. Maybe install script must be adjusted.
I use gpac to rewrap an elementary stream into a standard MP4 file but for that, I'm including an internal header: <gpac/internal/isomedia_dev.h>. The word "internal" means it's not intended to be used but headers are installed, functions exported and I don't want to spawn an mp4box process for that. Do you plan to make them public or to keep them exported in the foreseeable future?
Thanks!

Hello,
I'm doing some video transmission experiments over SDNs, and i need to obtain the same exactly video that is being displayed in MP4Client. The video is played from an HTTP server, when the network bit rate is too low it freezes (what's expected), and i need that video with the frozen part into a file, e.g. If the video have a duration of 40 seconds and it freezes at second 23, the last frame displayed must be the same in the last 17 seconds. I'm able to get a video in the cache directory but it only contains the fluid part (so this video only lasts 23 seconds, not 40).
Is there any way to 'screen record' what MP4Client is playing on the client side through time? In other words, can i get exactly what the client is seeing into a file?

Hi, just a question. I'm trying to make a multi-period MPD. I want every period to correspond with an .mp4 file which will have different segment duration, bitrate, etc. In addition, I want the manifest to use SegmentTemplate for segment localization. I've tried using -url-template and -out file1.mp4:period=<name> but dash.js will play the first 2 periods and get stuck on the third. I know it can be done for a fact because I have an example mpd that was generated with gpac by someone else, that works (ezample from DASH-IF Testvectors). http://dash.akamaized.net/dash264/TestCasesIOP33/multiplePeriods/4/manifest_multiple_Periods_Different_SegmentDuration.mpd
I also read that parameters for each periods can be done by referencing a text file, but I cannot find much info about it on the doc. Thank you in advance.

If I convert a m3u8 with
#EXTM3U
#EXT-X-VERSION:7
#EXT-X-TARGETDURATION:7
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-MAP:URI="init.mp4"
#EXTINF:4.416667,

bunny4.m4s
#EXTINF:4.000000,
bunny5.m4s
#EXTINF:2.958333,
bunny6.m4s
#EXT-X-ENDLIST
I get something like this
<SegmentList duration="7000" startNumber="0">
<Initialization sourceURL="init.mp4"/>
<SegmentURL media="bunny0.m4s"/>
<SegmentURL media="bunny1.m4s"/>
<SegmentURL media="bunny2.m4s"/>
<SegmentURL media="bunny3.m4s"/>
<SegmentURL media="bunny4.m4s"/>
<SegmentURL media="bunny5.m4s"/>
<SegmentURL media="bunny6.m4s"/>
</SegmentList>
To get it working I have to change it to
<SegmentTemplate timescale="1000" initialization="init.mp4" media="bunny$Number%01d$.m4s" startNumber="0">
<SegmentTimeline>
<S t="0" d="4416" />
<S d="4000" />
<S d="7333" />
<S d="4000" />
<S d="3291" />
<S d="4000" />
<S d="2958" />

If you are converting from m3u8 to mpd the timescale value is missing.
For example:
<SegmentList duration="4000" startNumber="0">
has to be edited to
<SegmentList duration="4000" timescale="1000" startNumber="0">

I have an apache server with mpd and associated segments.I tried connecting to this server from another Pc using MP4Client.By default it plays the highest resolution video.How do I check/confirm that the video will change bit rate.Could someone suggest me an idea/sample code ?

I have a single video which is re-encoded to various bit rates. I have generated the corresponding mpd file also.It plays using MP4Client. I used the following command:
MP4Box -dash 4000 -frag 4000 -rap -profile onDemand -segment-name %s/segment_ -url-template -out manifest.mpd video-240.mp4#video video-360.mp4#video video-480.mp4#video video-720.mp4#video video-audio.mp4#audio
But it generates only a single segment for each bit rate.how to generate the corresponding segments(i.e segment list) also for all the bit rates.

MP4Box -dash 1000 -rap -frag-rap -profile onDemand -out video.mpd video4k.mp4 video-1080.mp4 video-720.mp4 video-480.mp4 video-360.mp4 video-240.mp4 video-audio.mp4
It gives me error:
[DASH] Cannot open file video4k.mp4 for dashing: Requested URL is not valid or cannot be found
DASH Setup Error: Requested URL is not valid or cannot be found

4K Video: Cannot open file video for dashing

Hello all,
Thanks to MP4Box I can generated my own video segments (m4s) and mpd files. But I have some difficulties to put them on the server. I was wondering whether .mpd file needs a specific Web Server ?
First I tried with my personal Http Web Server, by given the http://www.aaaa.com/file.mpd my browser just display the xml file <title> content. However, with some online .mpd file examples, after putting the mpd address in my browser, it asked me whether i would like to donwload it as a file.
I also tested putting MP4Box generated files (a set of m4s files and mpd) to my AWS EC2 instance. But it remains the same, my browser just displayed the pure text of the <title>, no download request as the online examples. As far as I know, the AWS EC2 is CORS enabled.
I need a special server to store these generated mpd and m4s files ? or I need to do to some configurations on my AWS EC2 instance ? any suggestions ?
thanks a lot

I'm trying to multiplex these files:
https://drive.google.com/open?id=1XAYDoTzqO9jJFyCI9VcrIWEVNpwnM6gI
using (MP4Box - GPAC version 0.7.2-DEV-rev985-g6096388c4-ab-suite):
```
MP4Box -par 1=1:1 -add "E:\Temp\112_15_32_58_2410_02.264"#video:fps=25:delay=80 -brand avc1 -add "E:\Temp\iId_2_aid_4352_ms_15_32_58_2410_01.ac3"#audio:lang= -itags tool="Hybrid 2019.01.02.1" -tmp "E:\Temp" -new "E:\Output\15_32_58_2410__04.mp4"
```
I get:

```
as output, but that's it MP4Box is stuck and never closes the 0000000000B76BB0_isotmp file inside the temp folder.
I first thought that the audio was the problem, but leaving out the audio doesn't fix the issue either.
Muxing the two streams using ffmpeg works fine.

Hi,
I created DASH segments (set of *.m4s files and an mpd file) using MP4Box. The MP4Client plays the mpd file perfectly. I am trying to replace one of these .m4s files with some other random .m4s file. I see the obvious errors such as _incorrect sequence number_ as shown below. I tried to edit the .m4s file to match the original one but I am failed to so successfully.
```
[iso file] Warning: wrong sequence number: got 1 but last one was 29031
Sample 2 (size 17955) rewrite: corrupted NAL Unit (size 50200577)

```
There is an existing thread [here](https://sourceforge.net/p/gpac/discussion/327349/thread/de499f7f/). Some of the answers are from **Romain**. But, I still I haven't figured out how to modify the .m4s file with correct details. Any comments? Thank you.
