"gpac",
"gpac"
] | I've noticed that when I try to multiplex multiple tracks in a fragmented MP4 file, only one moof is created. If I remove the second track then moof's are created as usual. Is this a bug or I'm doing something wrong in multiplexing multiple tracks?

"gpac",
"gpac"
] | Hello. I have encountered a weird issue.
What I'm doing:
- Generating .ts file with `gpac -i input.mp4 -o output.ts:temi="#N#url"`, gpac 2.5-DEV-rev360-ge3fdb474-master (Windows 10)
- Modulating in DVB-T with DekTec modulator.
- Receiving in another computer with an app that depends on GStreamer.
- Playing video in the GStreamer app and retreiving url in TEMILocation.
I also have the Windows binaries of gpac 0.8.0, and I have also generated another .ts file with mp42ts, because that's what the people that started the project I'm working on did back then.
The command they used (and the same I used to generate the .ts file) is the following:
`MP42TS -real-time -rate 30000 -src=input.mp4:ID=103 -pcr-init=750 -insert-ntp -temi http://192.168.0.37/index.xml -dst-file=output.ts`
Ok now with the issue. The video generated with mp42ts (gpac 0.8.0) plays perfectly from the GStreamer app, while the video generated with gpac 2.5 doesn't. They both play perfectly in VLC.
Differences between both files:
**video generated with mp42ts (gpac 0.8.0)**
- Has a size of approximately 10 times the size of the .mp4 source.
- `gpac -i video.ts inspect` shows a bunch of errors like this: `[ADTSDmx] Unsupported multi-block ADTS frame header - patch welcome`
- In the GStreamer app, with GST_DEBUG=3, I see a lot of messages like this `<autoaudiosink-actual-sink-pulse> [00m correct clock skew -0:00:00.024353613 < -+0:00:00.020000000` but the video plays perfectly fine and there are no more warnings.
**video generated with gpac 2.5**
- Has approximately the same size as the .mp4 source.
- `gpac -i video.ts inspect` shows correct info on the file.
- In the GStreamer app, video playback works but it stops a lot. With GST_DEBUG=3, I see the same "correct clock skew" messages that I get with the other .ts file, but there is also this (I removed the debugging timestamps to make it a bit more readable):

```
It works, but by some reason, I can not switch bitrates through "Bitrates" control of dash.js ([reference dash.js](https://reference.dashif.org/dash.js/latest/samples/dash-if-reference-player/index.html))
But I can do it through "Tracks" control.
Still 1 bitrate
But 2 tracks. I can change the quality here.
What I have to change in MP4Box command, to switch bitrates via "Bitrate" control instead of "Tracks"?

Thank you for an outstanding and powerful toolset.
I make a stream from consequently running `MP4Box`, from mp4 files with subtitle track.
VTT subtitles are embedded with MP4Box.
```
MP4Box \

```
I have been adding subtitles before:
```
MP4Box -add subtitles.vtt:FMT=VTT:lang=en segment.mp4
```
The first run says, that there's problem with subtitle bitrate.

The stream runs normally at some extent. But few minutes after of stable work, the `MP4Box` start producing dozens of warnings on each run. The length of these "delays" and count of lines increases on each run.
Example of 42th run:
```

] | I'm rescuing an old project from my department and I need to generate a transport stream file with an URL in the TEMI Location descriptor and with timestamps. The transport stream will be modulated in DVB-T, received and played by a GStreamer app in another computer. The colleagues that started the project used MP42TS utility to transform an mp4 file to .ts with the following command:
`MP42TS -real-time -rate 30000 -src=input.mp4:ID=103 -pcr-init=750 -insert-ntp -temi http://192.168.0.37/index.xml -dst-file=output.ts`
What they did was run this command, wait for the duration of the file (if the video lasted 5min they waited exactly 5min) and then they stopped execution. I don't think this is the way to go, but before fixing their mistakes I would like to be able to reproduce their workflow with modern GPAC. With the generated .ts file from the command above, I am able to play it back in the receiving computer and I'm also able to retrieve the URL.
I have tried the following two commands:
`gpac -i input.mp4 -o output.ts:pcr_init=750:temi="#N#http://192.168.0.37/index.xml"`
`gpac -i input.mp4 -o output.ts:pcr_init=750:temi="http://192.168.0.37/index.xml"`
The first one plays, and that seems to indicate that the NTP timestamps are placed correctly. The second one doesn't play. I cannot retrieve the URL from any of these.
I have also tried adding the -real-time and -rate options, but the resulting file didn't even play in VLC.
Thanks in advance for any guidance, and thanks for such a good tool like GPAC. | m2tsmux usage question | https://api.github.com/repos/gpac/gpac/issues/2897/comments | 2 | 2024-06-28T09:51:24Z | 2024-07-02T07:50:35Z | https://github.com/gpac/gpac/issues/2897 | 2,380,039,848 | 2,897 |

We came across a problem when muxing multiple VVC bitstreams separately and then concatenating them using MP4Box: The parameter sets are dropped from all but the first source file. Specifically this problem pops up, when the individual bitstreams are encoded with different rates. The encoder stets the base QP in the PPSs differently, so the PPS from the later bitstreams also need to be present.
This is how to reproduce the problem:
```
MP4Box -add out1.266 -new out1.mp4
MP4Box -add out2.266 -new out2.mp4
MP4Box -new cat.mp4 -add out1.mp4 -cat out2.mp4
```
If you try to play the resulting cat.mp4 file, the decoder exits with an error, because it can not decode the second part of the file due to the wrong PPS. A workaround is to specify `--xps_inband=all`, when creating the individual files, but I think the concatenation should detect that the parameter sets are incompatible and also keep those of the later bitstreams. If that is not possible or wanted, at least a warning should be issued, that the file might not be playable.
Note: the PPSs all have the same parameter set ids, since the files were encoded separately, so the content of the raw NAL units needs to be compared.
Also, two more things I noticed when using --xps-inband:
- `--forcesync` is required to ensure `-add` does not drop the in-band parameter sets for CRA-frames, even if they were present in the source file.
- `--xps_inband=all` doesn't work when using `-cat` with MP4 files, I don't know if this is intentional.

Afterwards I extracted all the I-frames/keyframes from the encrypted video using FFMPEG, I found that only first keyframe is entirely encrypted and later keyframes are not entirely encrypted or not encrypted at all. Is this how its supposed to work or am I doing something wrong? Also, I'm interested in knowing how GPAC implements this selective encryption of RAP. Does GPAC identify the particular bytes occupied by the keyframe in the video and then encrypt only that much? I tried looking at the source code but couldn't understand much. I'm a little new to this work so apologize if I'm asking something trivial, I would really appreciate some help.

I'm trying to add rescaler to my MPEG-DASH stream.
I have two installations of GPAC: local and in the remote Docker container.
Both installations were made from master branch of GPAC (version 2.5-DEV-rev268 in local computer, version 2.5-DEV-rev278-gd594d3f2c-master in container).
When I run it in my local computer, it works just fine.
When I run it inside docker container in remote server, it failed with error:
```
Failed to load filter ffsws:osize=320x240: Filter not found
Arg utcs set but not used
Arg force_flush set but not used
Arg segdur set but not used
```
I checked
```
gpac -h filters | grep ffsws
```
and there's no such filter in Docker installation. While in local computer it present.
Should I install some library in the container and reinstall GPAC?

I continue my attempts to make Mpeg-dash stream with adaptive bitrate. It is related with issue [2868](https://github.com/gpac/gpac/issues/2868).
In order to achieve this, I'm trying to rescale with MP4Box on the fly.
```
MP4Box -dash 2000 \
-dash-ctx /dev/shm/broadcast/context.txt -profile dashavc264:live \
--utcs="https://time.akamai.com/?iso&ms" \
-mpd-refresh 2 \
-dynamic \
-bs-switching merge \
-segment-timeline -url-template \
-insert-utc \
-min-buffer 15 \
-mpd-title "Test ABR" \
-time-shift 30 \
/dev/shm/broadcast/input.mp4#video:dur=10:@ffsws:osize=160x120@enc:c=avc:b=100k:#Representation=Rep1@@ffsws:osize=320x240@enc:c=avc:b=200k:#Representation=Rep2 \
/dev/shm/broadcast/input.mp4#audio:dur=10 \
-out /dev/shm/broadcast/manifest.mpd
```
First run is successfull
Second run brings errors and stream doesn't play after first segment.
```

- [x] I tried with the latest version of GPAC. Installers available at https://gpac.io/downloads/gpac-nightly-builds/
- [x] I give enough information for contributors to reproduce my issue.
Greetings again.
I have tested GPAC as webserver, and I have no luck with this. (
I have a refreshing playlist which is reloading each 10 mcsec, and I try to make a stream from files in playlist.
Each file has 10 seconds duration. I start with this command:
```
gpac -i /var/www/streamer/storage/app/video_chunks/playlist_1.m3u:ka=10 --segdur=10 --cdur=10 --profile=live --dmode=dynamic --sreg --rdirs=/tmp/broadcast -o http://localhost:8085/live.mpd
```
And trying to play it in dash.js, which is running on local web server. It plays sample streams from different domains, i have tested.
The stream doesn't play, because it doesn't find appropriate video chunks.
When I checked output dir, I really didn't see requested files, like `GPAC` is not refreshing them at all:
The manifest is being okay, but stream doesn't play, the screen of player just flickering..
```

Running GPAC for generating an HLS/DASH stream with CMAF from a live TS stream containing ID3 tags, sometimes duplicates tags in the CMAF segments. It's hard to diagnose, but I managed to find a test file that can be used to reproduce the problem. I will share it privately.
```bash
gpac/bin/gcc/gpac \
-i example.ts \
-o gpac_local/playlist.mpd:gpac:dual:gpac:buf=-150:ll_part_hb=-1:seg_sync=no:segdur=1.0:cdur=0.2:llhls=sf:hlsc=true:cmaf=cmf2:dmode=dynamic:pssh=mv:template=segment:keep_segs=true
```
With the sample file, segment 1270 has 2 ID3 tags with the same content.
Adding some log lines here https://github.com/gpac/gpac/blob/master/src/filters/mux_isom.c#L6425 I don't see the logic for deduplicating emsg boxes being activated. The `moof` box always arrives with zero `emsg` boxes here.

Greetings.
My goal now is, to add different representations with different bitrate to live mpeg-dash.
I'm feeding chunks one by one, calling MP4Box for each, making live stream.
To achieve this I'm trying:
```
MP4Box -dash 10000 \
-dash-ctx /dev/shm/broadcast/context.txt \
-profile dashavc264:live \
--utcs="https://time.akamai.com/?iso&ms" \
-mpd-refresh 2 -dynamic -bs-switching no \
-segment-timeline \
-url-template \
-insert-utc \
-min-buffer 15 \
-time-shift 30 \
/dev/shm/broadcast/input.mp4#video:@ffsws:osize=160x120@enc:c=avc:b=100k:#Representation=1@@ffsws:osize=320x240@enc:c=avc:b=200k:#Representation=2 \
/dev/shm/broadcast/input.mp4#audio \
-out /dev/shm/broadcast/manifest.mpd
```
The first run of MP4Box is successfull, but the next run of MPEG_DASH with same command line fails
```

Hello again, excuse me for annoying questions, but I really didn't find any information anywhere.
The problem is, that our MPEG-DASH stream suffers from large download time. 1.2 Mb chunks are downloading for 0.7-1s.
Maybe I'm on wrong way totally..but, I decided to try out `node-gpac-server`.
I read the [article](http://biblio.telecom-paristech.fr/cgi-bin/download.cgi?id=14719), and as I understood, I need to mark each segment with `eods` marker.
How I can achieve it with `MP4Box`?
Thank you.

Second, I have a question.
When i make my manifest with `MP4Box` ( version GPAC 2.5-dev), and play it in [DASH reference player](https://reference.dashif.org/dash.js/latest/samples/dash-if-reference-player/index.html), I got a warning:

I checked the manifest and didn't find [mentioned element.](https://github.com/Dash-Industry-Forum/dash.js/wiki/UTCTiming---Clock-synchronization).

`--utcs='https://time.akamai.com/?iso&ms' `

What I currently do is first encode the mkv/mp4 videos to my base format using ffmpeg.
**Command:**
```
encode_command = [
os.path.join(BIN_DIR, "ffmpeg"),
"-i", raw_file_location,
"-c:v", "libx264",

"-c:s", "mov_text",
"-movflags", "faststart",
"-f", "mp4",
"-y",
"-map", "0",
encoded_file_location
]
```
This gets encoded successfully.
Now, mp4box processing with the encoded file:
```
split_command = [
MP4BOX_PATH,
"-dash", "5000",
"-frag", "5000",
"-profile", "dashavc264:live",

"7cd2d8fe0b0a:fmt=video/x-matroska#trackID=3:id=sub1",
]
```
Now after processing size of the folder gets 4x times. Even if I don't encode the video and directly process mp4box, 3-4x size increase is visible. For example :
last file encoded size was 520MB. and after MP4BOX processing it reached 2GB of the size.
nonEncoded file: 443MB after process is become 1.73GB.

Basically I'm loading `fin` then two `reframer` consecutively. I then explicitly define the connections. The resulting graph has two `mp4dmx` going to reframers. I was expecting this fanout to happen after `mp4dmx`. I know I haven't given any implementation details but I just want to know if this is expected given the flags list above.

] | Hello, I have tried searching the issues for a potential solution.
I am recording individual JPEG frames saved to a folder in order. They are denoted img_1.jpg to img_x.jpg. I wanted to "containerize" the jpeg frames into an MJPEG formatted video (like .AVI format), and I attempted to use the following command to do so, but it did not work.
```
gpac -i img_%d.jpg compositor:fps=30 vout:ext=avi:fps=30
```
Error: `Failed to load filter for "img_%d.jpg": Requested URL is not valid or cannot be found`
Is this a supported use case? I know I could use img_1.jpg+img_2.jpg+... as stated in the docs, but if I have an arbitrary number of images, this would not be ideal.
I am avoiding using FFmpeg/Gstreamer due to integration constraints for my project, and I already have gpac integrated quite well, so this would be very convenient. Thank you in advance for your consideration and help.

It seems from the documentation that only extraction of single items can be currently done.

Detailed guidelines: https://gpac.io/bug-reporting/
I'm trying to transmit live subtitles from our transcoder to GPAC using Transport Stream. Our transcoder does not support MP4 Text Stream, and from what I have read of GPAC's code, it does not support demuxing it either.
Instead of implementing the whole spec, which at the moment is overkill for my use case, I tried to mux SRT subtitles as private data in PES packets.
* The Elementary Stream uses PES packets private data with a `registration_descriptor` for the `SRT ` format.
* Each PES packet contains one SRT event (aligned with PES start):
```
0
00:00:00,000 --> 00:00:01,000
This is the event zero
```
In GPAC, I managed to demux the stream in this branch: https://github.com/gpac/gpac/compare/master...jadarve:gpac:NS_ts_subtitles
running a command like:
```
./bin/gcc/gpac \
-i test_data/out_subtitle_only.ts \
txtin \
-o test_data/subtitles.vtt \
-graph
```
prints the following graph:
```
Filters connected:
fin (src=test_data/out_subtitle_only.ts) (idx=1)
-(PID out_subtitle_only.ts) m2tsdmx (dyn_idx=4)
--(PID P1T2) writeuf (dyn_idx=5)

------(PID P1T2) writegen (dyn_idx=8)
-------(PID P1T2) fout (dst=test_data/subtitles.vtt) (idx=3)
```
However, the generated WebVTT is not what I expected, it looks as:
```
WEBVTT
90:15:36.023 --> 90:15:39.623
1
01:00:00,000 --> 01:00:00,000
0
00:00:00,000 --> 00:00:00,040
current counter: 00000000000000000000000000000000000000000000000000
```
where I expected lots of subtitles lines.
This is just an example. My final goal is to be able to mux the TS subtitles into a CMAF track as WebVTT for live streaming. I would like to know if something is already done in that direction (live subtitle muxing), or if the approach I'm taking makes sense, and if you could advise me on how to proceed. | Support live subtitles stream from transport stream | https://api.github.com/repos/gpac/gpac/issues/2843/comments | 0 | 2024-05-23T15:51:17Z | 2024-05-23T15:51:17Z | https://github.com/gpac/gpac/issues/2843 | 2,313,269,517 | 2,843 |

Mp4box writes 1..N samples to a ttml subtitle file (segdur=8s), sometimes it may have just one sometimes `MOOF/TRAF/TRUN.samplecount=3 (dur=1000, dur=4000, dur=3000)` items.
Is it possible to force ttml text lines go to a single sample within a segment file?
```

Or is it [NHNTStream](https://concolato.wp.imt.fr/2014/01/27/first-attempt-at-storing-ttml-in-mp4/) only option, I need to preprocess ttml.xml files to NHNT inputs (one per segment splitted by segment timeline + text line times)?
I believe LiveSim2 supports only `one sample per subtitle_123.m4s segment file` at the moment if using my own vod2live test material. | Force ttml 123.m4s segments to use just one sample(TRUN.samplecount=1)? | https://api.github.com/repos/gpac/gpac/issues/2842/comments | 4 | 2024-05-23T08:21:44Z | 2024-06-13T10:02:44Z | https://github.com/gpac/gpac/issues/2842 | 2,312,275,432 | 2,842 |

Hello!
I've tried injecting multiple channels to mv-hevc mov prores file using the Mp4box, but the number of channels is always reduced down to 3.
Is it possible, and how, to inject multiple channels (like ambisonics or dolby 5.1)?

```shell
mp4box -new -add /path/video.mov -add /path/audio.aac /path/finalvideo.mov

gpac -i /videos/result/index.ghi:gm=init:rep=2 -o /videos/result/master.mpd
```
Generating playlist for hls and dash also works
3 - However when generating segments it works for represention 1 but not for 2
```bash
# works
gpac -i /videos/result/index.ghi:rep=1:sn=1 -o /videos/result/master.mpd
# not working
gpac -i /videos/result/index.ghi:rep=2:sn=1 -o /videos/result/master.mpd
```
It gives the following error:
```
Filters not connected:
fout (dst=/videos/result/master.mpd) (idx=2)
```
I notice also in the index on representation 2 the mimeType is `audio/mp4` which is correct, and in the props its `<prop type="MIMEType" value="video/mp4" />`
Don't know if it can make the filters fail ?

There is a workaround to make it work (hope this helps someone) - adding the `-no-block=all` parameter helps in both cases, but this is hardly obvious. See the full command below:

] | Hello,
I need to extract some additional data (GoPro GPS data) from a MP4 file and add them to another MP4 file.
I'm able to extract them with the command
`mp4box.exe -raw 3 ..\video.mp4`
But when I try to import them again with this command
`mp4box.exe -add ..\GoproVideo.mp4 -set-meta meta:tk=3 -add-item ..\video_track3.gpmd:tk=3 -new output.mp4`
I got the following error
`Trying to add item, but missing meta box`
Am I missing something? Looking at the documentation, command line seems ok because I set the meta type and then add the item to it. Should I create first the track3? Or is automatically created with the set-meta command?
This is what I get if I run a -info on the original file
```

There is only one property with a given name per packet. This is an issue for example when a stream of packet carry the property and the packet rate is diminished: some of these properties are lost.
Another example (related to https://github.com/gpac/gpac/pull/2748) is id3 metadata. When carried in MPEG-TS PES streams they may not have any PTS. We then assign them to the next (audio) packet. However if we get several of them at once they are not merged but silently lost ; the mpeg2-ts demuxer could merge them but the current API doesn't allow it.

Ah je crois avoir compris
Ce serait bien d'améliorer la doc de "File import / export"
Par exemple ajouter:
"In order to load your own files, this page uses the "imp" command"
"Once you have run gpac or MP4Box to produce a new file, you can download it by running "exp FILENAME" where "FILENAME" is the output you gave in the MP4Box or gpac command line

```
typo:
"to design a file not on Emscripten's file system" -> "to designate a file not on Emscripten's file system"
```
```
"Otherwise, NAME designs a file to be picked on the user's file system" -> "Otherwise, NAME designates a file to be picked on the user's file system"
```
```
"This syntax CANNOT work when editing files (MP4Box, dasher context, etc...)."
Je comprends pas ce que ça veut dire
```
```
Je comprends pas vraiment comment utiliser "imp"
ce serait bien d'avoir des exemples
je viens d'essayer "imp" tout court, ça ouvre un file picker, ce serait bien de commencer par dire ça
Ce serait bien de clarifier que les fichiers ne sont pas uploadés sur un serveur GPAC, que tout reste en local
je pense que certains utilisateurs voudraient bien tester mais ne veulent pas que leurs fichiers soient uploadés sur un serveur GPAC
```
```
cette phrase est bizarre:
"If writable stream failure, the file will be stored in memory until final write or canceled."
je comprends pas vraiment ce que ça veut dire
```
```
je viens de comprendre ce que fait l'exemple "download remote DASH content" c'est pas immédiat. Si je comprends bien ça download dans le repertoire "dump" mais l'utilisateur doit ensuite executer "exp dump/" ?
Ah non, "exp" ne marche que pour un fichier
donc en gros, l'utilisateur doit se taper tous les "exp" 1 par 1
l'utilité de l'exemple est limitée
```
```
l'exemple d'extraction n'affiche rien, c'est normal? la ligne de commande a disparu ...
par contre "exp xs0-xe02.mp4" fonctionne
```
```
c'est une super idée cette page, mais je pense qu'il faudrait la mettre entre les mains d'un utilisateur novice et observer comment il l'utilise, et corriger/améliorer
"threaded" on, ça ne change rien:
```
```
Je rajouterais une phrase en intro qui dit:
"If you want to process your own files, you must first import them into the environment (see "imp" command below). Note that the files are only imported locally into your browser memory, they are not uploaded to any server. Similarly, if your command line produces any output, the output is only present in the environment. If you want to download them, you have to export them (see the "exp" command below)"
Je réorganiserais/corrigerais aussi:
"Usage
This page allows running the MP4Box and GPAC applications in web browsers.
Select an example and make edits, or type in your own command. Finally press Enter key or click the Run button.
The environment does not contain any source media file. You can use remote URLs (e.g. http URLs) or, if you want to process your own files, you must first import them into the environment (see "imp" command below). Note that the files are only imported locally into your browser memory, they are not uploaded to any server.
Similarly, if your command line produces an output, the output is only present in the environment. If you want to download them, you have to export them (see the "exp" command below).
Remote DASH and HLS playlists can be used as input, provided that they are hosted with proper CORS configurations.
The environment also provides basic shell file system and support advanced gpac configuration (see below).
NOTE: The webassembly build is experimental. It tries to uses webcodecs whenever decoding or encoding is involved. If webcodecs can't be used, it falls back to software implementation running in wasm.

I have not tried it with 6.1 AAC, but I've generally had bad luck with most web browsers and **any** AAC channel configuration that isn't 5.1, stereo, or mono.
I _believe_ it should be writing either or both of those channel configurations:
```
<AudioChannelConfiguration schemeIdUri="urn:mpeg:mpegB:cicp:ChannelConfiguration" value="11"/>
<AudioChannelConfiguration schemeIdUri="tag:dolby.com,2014:dash:audio_channel_configuration:2011" value="F901"/>

The first value is from [page 237 of ETSI TS 106 366](https://www.etsi.org/deliver/etsi_ts/102300_102399/102366/01.04.01_60/ts_102366v010401p.pdf).
The second was derived using:

"gpac",
"gpac"
] | I have encountered an issue with MP4Box where it fails to generate initialization segments for all audio profiles when multiple audio tracks with the same sample rate but different bit rates are used.
Steps to Reproduce:
Created video and audio MP4 files with required resolutions and sample rates using the following FFmpeg commands:
For video
`ffmpeg -y -i video30.mp4 -c:v libx264 -r 24 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -vf scale=-2:1080 -b:v 5000000 -maxrate 5000000 -movflags faststart -bufsize 5000000 -profile:v main -preset fast -an "1080.mp4"`
`ffmpeg -y -i video30.mp4 -c:v libx264 -r 24 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -vf scale=-2:720 -b:v 3000000 -maxrate 3000000 -movflags faststart -bufsize 3000000 -profile:v main -preset fast -an "720.mp4"`
`ffmpeg -y -i video30.mp4 -c:v libx264 -r 24 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -vf scale=-2:540 -b:v 1499968 -maxrate 1499968 -movflags faststart -bufsize 1499968 -profile:v main -preset fast -an "540.mp4"`
`ffmpeg -y -i video30.mp4 -c:v libx264 -r 24 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -vf scale=-2:360 -b:v 699968 -maxrate 699968 -movflags faststart -bufsize 699968 -profile:v main -preset fast -an "360.mp4"`
For audio
`ffmpeg -y -i video30.mp4 -map 0:1 -vn -c:a aac -b:a 130828 -ar 48000 -ac 2 audio0.m4a
``ffmpeg -y -i video30.mp4 -map 0:1 -vn -c:a aac -b:a 137500 -ar 48000 -ac 2 audio1.m4a
``ffmpeg -y -i video30.mp4 -map 0:1 -vn -c:a aac -b:a 135812 -ar 48000 -ac 2 audio2.m4a
``ffmpeg -y -i video30.mp4 -map 0:1 -vn -c:a aac -b:a 130911 -ar 48000 -ac 2 audio3.m4a
`
Used MP4Box with the following command to create a DASH manifest:
`MP4Box -dash 4000 -frag 4000 -rap -segment-name 'segment_$RepresentationID$_' -fps 24 1080.mp4#video:id=1080p 720.mp4#video:id=720p 540.mp4#video:id=540p 360.mp4#video:id=360p audio0.m4a#audio:id=0:role=main audio1.m4a#audio:id=1:role=main audio2.m4a#audio:id=2:role=main audio3.m4a#audio:id=3:role=main -out master.mpd
`
After executing the above commands, only the initialization segment for the first audio profile (audio0.m4a) is generated as segment_0_.mp4, but no initialization files are created for the other audio profiles (audio1.m4a, audio2.m4a, audio3.m4a). However, segment files are present for all audio profiles; only the initialization files are missing.
Additional Information:
1. The issue seems to occur specifically when multiple audio tracks with the same sample rate but different bit rates are used.
2. This problem does not occur with the video streams; they are generated correctly as expected.

I have just downloaded GPAC 2.5-dev a few days ago and tried to install.
After installation, I double click to start the application.
The application does not open.
I have tried version back to 2.4. Still the same.
Before install 2.4 and 2.5-dev, there was an older one, I have forgotten the version number but it did open.
See what else information you need to know for troubleshooting.
Tried but of no positive effect:
2.4, 2.5-dev version

] | - [++ ] I looked for a similar issue and couldn't find any.
- [ +] I tried with the latest version of GPAC. Installers available at https://gpac.io/downloads/gpac-nightly-builds/
- [ +] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...). I can share files anonymously
Given: video fragments of equal length, prepared from some source stream by segmenting into 10s chunks.
Example command of preparation:
```
ffmpeg -loglevel verbose -i <SOURCE_URL> -c:v libx264 -c:a aac -preset veryfast -force_key_frames 'expr:gte(t,n_forced*2)'
-f segment -segment_time 10 -reset_timestamps 1 -map 0 "/chunks/seg_%03d.mp4"
```
So we have seg_0001.mp4, seg_0002.mp4 etc.
You can download prepared files from here: [link](https://www.dropbox.com/scl/fo/024n472bairtmuz2e1lzi/AHn5Gj0sVwcTGfMn4l1_oBA?rlkey=6d063m5gy01un4at2mx0eocmx&st=ukdpih91&dl=0
)
Goal:
Dash these segments sequentially, as the next segment becomes fully written and ready.
Example commands:
````
# First copy seg_000[1,2,3...].mp4 to input mp4
# Then:
MP4Box -dash 10000
-dash-ctx ./stream/context.xml
-profile dashavc264:live
-mpd-refresh 20
-dynamic
-bs-switching no
-segment-timeline
-url-template
-time-shift -1
input.mp4#video
input.mp4#audio
-out ./stream/stream.mpd
````
Estimated result: the dash manifest plays in dash.js player or[ reference dash-if player](https://reference.dashif.org/dash.js/latest/samples/dash-if-reference-player/index.html). When the next segment is adding to manifest, it is playing next.
Obtained result: dash.js plays only first 10s fragment, and then hangs.
I tried:
* changing mpd-refresh
* changing time-shift
* changing profile to live and back to dashavc264 live
* adding/replacing segment-timeline and url-template
* adding :sreg for mpd
* adding -subdur
* adding -frag
* changing dash length
* adding min-buffer
* adding :ddur for sources
* adding ..everything i found
* removing `input.mp4#audio` source *--- WHOA! it's helped*! But I don't hear sound )
Addendum: when I remove -dash-ctx, it plays with sound, but loops around the initial fragment, as expected. I have a vague feeling that there is a problem somewhere in keeping sound in dash-context. It is surely my musings and no more.
What helped else?
When I substitute to source the actual filename, instead of renaming it to "input.mp4", then, everything works.
*But*, the `stream.mpd` and `context.xml` are constantly growing, because there are emerging new `Period` xml-entities. I've posted about it in the issue #2801
So, it would be cool if you fix that problem with live streaming with sound.
Cheers!

"gpac",

] | **Description**
Function [gf_gz_decompress_payload_ex()](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/utils/base_encoding.c#L252) passes uninitialized buffer `data` to the function `inflate()` (through `d_stream.next_in`)
**Details**
In [box_funcs.c:118](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/isomedia/box_funcs.c#L118) `size` is read from the input. This value is then used to allocate memory ( in [box_funcs.c:198](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/isomedia/box_funcs.c#L198)); the allocated buffer should be initialized by the function `gf_bs_read_data()` in [box_funcs.c:202](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/isomedia/box_funcs.c#L202) but the return value of this function (i.e. the number of read bytes) is not checked. Regardless of how many bytes are read, the whole buffer and the `size` variable are passed to the function `gf_gz_decompress_payload_ex()` in [box_funcs.c:203](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/isomedia/box_funcs.c#L203) which then passes the (uninitialized) buffer to the function `inflate()` in [base_encoding.c:254](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/utils/base_encoding.c#L254).
A possible fix might be to check the return value of the function `gf_bs_read_data()` in [box_funcs.c:202](https://github.com/gpac/gpac/blob/205bfe3196764b61b19b63494a2b4708ac774b71/src/isomedia/box_funcs.c#L202) and either exit with an error or adjust the values accordingly if the expected size does not match the number of read bytes. The testcase provided in the PoC is only 10 bytes long, but triggers an allocation of millions of bytes since the first bytes appear to be interpreted as the size of the payload. The return value of the function `gf_bs_read_data()` with the given input is `0`.
**To Reproduce**
The [attached archive](https://github.com/gpac/gpac/files/15096139/gpac.zip) contains:
- the executable on which we performed our tests (commit hash: 205bfe3)
- the input file to exercise the bug
- the stacktrace when the bug was observed
- the output of Valgrind confirming our finding
At least for this testcase, a memory safety tool is required to expose the bug. To reproduce, run the given binary with the testcase file inside valgrind with a command like `valgrind --track-origins=yes ./fuzz_parse uninit_mem/testcase`.
The binary in the archive is a compiled version of the fuzzing harness you made available for OSS-Fuzz (i.e. `testsuite/oss-fuzzers/fuzz_parse.c`), with a main() function that simply opens a file, reads its content and calls the LLVMFuzzerTestOneInput() function. To compile, we used clang 14 and we ran every test on an ubuntu 22.04 x86-64 machine.
**Impact**
Use-of-uninitialized-memory violations can lead to security issues, but we could not assess the potential impact of this one in depth. We believe the severity (e.g., a local DoS from crash) will depend also on how erratically inflate() may behave on the random data from the uninitialized buffer. Since the testcase we generated does not cause a cash, we followed your policies in `SECURITY.md` and reported it here.

We are making stream, consequently feeding MP4Box with new video-fragments
```
MP4Box -dash 10000 -dash-ctx ./stream/context.txt -rap -profile dashavc264:live \
-mpd-refresh 6 -dynamic -bs-switching no \

```
Everything is working good, except that fact, that MPD manifest grows very quickly.
Hour after it weighs 9 megabytes, which causes video freeze.
On the other hand, when I use Nginx to stream MPD, it keeps manifest size about 25 kilobytes.
Currently I don't see any workaround, except cleaning it from time to time. But, perhaps, there is some option to keep size in reasonable borders?

If I try to replace it with something else with `mp4box filename.mp4 -name 5="New Text"` I get "`New Text / Old Text`"
`MP4Box - GPAC version 2.2.1-rev0-gb34e3851-release-2.2`
Very frustrating.
**UPDATE:** There were apparently some UDTA's set, perhaps by HandBrake. I removed those and it worked as expected, still maybe some kind of overriding option wouldn't hurt. I would've never found this without doing `-info 5`. (And even then the `-udta` documentation could've been better since I'm not even sure what they are.) | name tkID appends text not replace | https://api.github.com/repos/gpac/gpac/issues/2794/comments | 1 | 2024-04-06T04:50:14Z | 2024-04-08T14:50:36Z | https://github.com/gpac/gpac/issues/2794 | 2,229,075,594 | 2,794 |

We created a subtitles [WebVTT file](https://github.com/gpac/gpac/files/14889478/subtitleVTT.txt), and transformed it to a TTXT file using the following GPAC command:
```
gpac -i subtitleVTT.vtt -o subtitleTTXT.ttxt

-o res/live.m3u8:cmaf=cmf2:rawsub=true:segdur=1:cat=auto

The issue with VoD session is that the MPD is scheduled at the end of the session.
There were also questions on using ```:forward=file``` versus ```:forward=mani```. And also with requiring ```atsc://```.

Greetings,
I installed GPAC android apk (stable release 2.2.1) on an ASUS_Z017DA phone (android 7). I then used it to play a mp4 file that was working in the GPAC client running on Linux. I found that I could hear the audio, but the screen was all black.
I have attached the relevant logs at the end of the post.
My questions are below:
• Are there any suggestions for solving this problem?
• Which version of the Android phone is working fine with the GPAC Client?
• What make/model of Android phone is recommended for use with the GPAC client?
Any hints are highly appreciated.
Thanks,
Ei Kyi Phyu Khin

I want to push a subtitles track into GPAC in live mode to generate a live HLS/DASH stream. Currently, the subtitles are pushed via a TCP socket from another application (see below).
The GPAC command is:
```bash
gpac \
-i tcp://0.0.0.0:9091:gpac:tsprobe=false:listen=true txtin \
-o res/live.mpd:dual:cmaf=cmf2:segdur=2:rawsub=true:dmode=dynamic -graph
```
From the command I expect GPAC to start creating the playlist and segments live while the VTT text arrives from the socket. What I see is that there are no files created in the `res` folder. And, when I stop the Python client (and the socket is closed), GPAC starts creating the playlist and segments as I expect them to be.
A given segment `0.0.0_dash1.vtt` looks like
```
WEBVTT
00:00.000 --> 00:01.000
Current time: 00:00.000
00:01.000 --> 00:02.000
Current time: 00:01.000
```
Am I missing something from the TCP connection to signal the `dasher` to produce the subtitles track live?
## Python client
This is the code for the `subtitles_client.py` client.
To run it:
```bash
python3 subtitles_client.py
```
which creates the WebVTT track, pushes it to the TCP socket, and prints the pushed string:
```
WEBVTT
00:00.000 --> 00:01.000
Current time: 00:00.000
00:01.000 --> 00:02.000

I'm trying to encapsulate a TTML chunk into an fMP4 container.
Related: #2730
Back then, when trying to do the same with WebVTT, I was finally succesful thanks to your guidance.
So I tried the same command but using TTML input, and the output seems to have some problem.
This is an example input:
```xml

As you can see, the xml content is duplicated inside the fMP4 container.
I didn't get playback on players, and that's how I end up checking inside the file. Didn't found a workaround with my known gpac commands, and this seems like some kind of error, so I create this issue here.
Tested with a mainline build minutes ago:
```

Trying the following GPAC command to generate CMAF2 HLS with raw subtitles (rawsub) is creating a m3u8 playlist with an init file, which GPAC doesn't create:
```
gpac \
-i output.ts \
-i subtitle.vtt \
-o res/live.m3u8:cmaf=cmf2:rawsub=true:segdur=1:cat=auto
```
We set the `rawsub=true`, which works fine, however, the following is the subtitles playlist generated:
```

```
Look to the tag `#EXT-X-MAP:URI="subtitle_dashinit.vtt"`, but the `subtitle_dashinit.vtt` file is not created, so, when we play the HLS VOD, subtitles don't show up.
The following is the filter graph of that command:
```

Seems like GPAC shouldn't add the `#EXT-X-MAP:URI` to the subtitles playlist if `noinitraw` flag is there?

] | For some reason, download manager is not working properly in a worker. Considering both the main thread and worker thread are running on their own thread, I can't find the reason why download manager experiences degraded performance while using gpac in a worker.
What happens is that when using worker and a remote source, gpac takes almost 60-70 times more to load the source. It seems that the reason lies with scheduling `fetch` promises while the same thread runs gpac. I've tried a very rough way to run `fetch` in seperate threads but I think I'm still blocked by scheduling. The correct way to achieve this seems to be through native (pthread) threading for download manager. Just how `-dm-threads` option supposed to work.
I would be happy to open a PR to bring `-dm-threads` to WebAssembly version but I need some guidance on what is needed and what might be a blocking issue. @jeanlf any idea on how to proceed with this one?
**My attempt at multi-threaded fetch:**
```js
let workerScript = `self.onmessage = async function(event)
{
let {url, options} = event.data;
let res = await fetch(url, options);
if (res.ok)
{
self.postMessage({
ok: res.ok,
url: res.url,
status: res.status,
headers: JSON.stringify([...res.headers]),
redirected: res.redirected,
body: res.body
}, [res.body])
} else self.postMessage({ok: res.ok, status: res.status})
}`;
let workerBlob = new Blob([workerScript], { type: 'application/javascript' });
fetcher._worker = new Worker(URL.createObjectURL(workerBlob));
fetcher._worker.onmessage = (event) =>
{
if (event.data.ok)
{
fetcher._state = 1;
fetcher._bytes = 0;
fetcher._reader = event.data.body.getReader();
let final_url = null;
if (event.data.redirected) final_url = event.data.url;
libgpac._fetcher_set_reply(fetcher.sess, event.data.status, final_url);
let headers = JSON.parse(event.data.headers);
headers.forEach(([value, key]) => {
libgpac._fetcher_set_header(fetcher.sess, key, value);
});

}

I have a question video audio sync.
when I try play hls-js, video-audio sync is out of sync.
My question is that is there possible to Performance improvement to make segment faster ?
(Now I am collecting data in segments in 2 sec)
when i make audio segments it takes about 1.97 seconds (from first audio data to callback),
video takes 1.98 seconds (from first video data to callback).
Could this have something to do with the out of sync?
(Also I am trying to use compress mode using `gf_isom_enable_compression` when I mux the video, Is it good choice ?)
Seconds question is
when i use `gf_isom_fragment_add_sample` this function

do I set the argument redundant_coding = 0,

For some unknown reason, the $Number$ does not resolve as init in the audio tracks. It does for video.
Even when nto specifying template names, I started noticing that for audio tracks the output init track was by default _dash.mp4 while for video tracks it was _dashinit.mp4.
I guess there might be a bug but I cannot find why or where. Maybe related to when there are several audio inputs? The file inputs have only one track each video or audio.
