I tried streaming a multiple track stream using gstreamer and package to hls it with gpac to then serve the segments with an origin, I notice that the option `max_cache_segs` is causing the playlist to be deleted.

```
GPAC command
```bash

-o /tmp/workdir/content/playlist.m3u8:gpac:dmode=dynamic:hmode=push:max_cache_segs=16
```
These commands creates a m3u8 playlist with the sub-playlist for each track in the input, but as mentioned before the playlist get deleted, making impossible to access to the stream, since the option `max_cache_segs` is for keeping a limit number of segments it shoudnt affect the number of playlist, also this happens only when the source has multiple tracks
In this GIF in shown that at the moment of running those commands all the playlist appear correctly, but get deleted almost instantly

] | Hello.
I have been using GPAC for over a year now and I find it amazing and easy to use, but there is one feature that I really want to use, and it is to be able to output to separate output directories for every source input I use.
I extract multiple resolutions from a video mp4 file to support variable bitrate for HLS and DASH video on demand. Then use GPAC to encode these mp4 files to [HLS and DASH](https://github.com/gpac/gpac/wiki/LL-HLS).
In the end, I get all encoded segments (.ts) in a single directory which is very confusing and not ergonomic. [Shaka Packager](https://shaka-project.github.io/shaka-packager/html/tutorials/hls.html#examples) has this feature and I want to use it with GPAC instead and don't know if it exists or not. | How to create separate output directories for multiple input sources? | https://api.github.com/repos/gpac/gpac/issues/2529/comments | 1 | 2023-07-16T07:55:46Z | 2023-07-18T05:06:09Z | https://github.com/gpac/gpac/issues/2529 | 1,806,487,712 | 2,529 |

Tiling low-definition images and high-definition videos with kvazaar, packaging them with mp4box, and then generating mpd and playing them live.
However, it takes too long for low-definition video to change to high-definition.
When I move the point of view, I want to change to high-definition tiles quickly.
So I tried to adjust the maximum buffer length to 4000ms using the mbuffer option, but the error "ARG mbuffer: 4000 set but not used" appears.
(used code: `mp4box -dash 2000 -rap --mbuffer 4000 -profile live -out mbuffer/dash_file.mpd lowvideo.mp4 highvideo.mp4`
This error also occurs when trying to utilize other options, and the option does not apply.
How do I fix this?
I'm running this on Windows.
Also, I was wondering what options are there to help low-definition tiles quickly change to high-definition. | mp4box option error | https://api.github.com/repos/gpac/gpac/issues/2528/comments | 1 | 2023-07-13T21:53:39Z | 2023-07-24T09:39:11Z | https://github.com/gpac/gpac/issues/2528 | 1,803,813,251 | 2,528 |

Hi everyone,
I want to assign different adaptation sets Id for each track of an UDP stream with multiple videos, so far I had no luck doing it using only one UDP stream, my approach was to stream multiple UDP each one with a different video, having multiple inputs allow us to modify the adaptation set and representation Id per input, generating the plalyst in the desired format.
There is an example of what I'm trying to do [here](https://github.com/JuanSalazar22/videoengineering/tree/main/0_transmit_multiple_tracks_with_gpac)
The gstreamer command I used is:
```bash
gst-launch-1.0 -v \

```
The GPAC command I'm using is:
```bash
gpac \
-i udp://225.225.225.225:5000/:gpac:listen=true:tsprobe=true:#ASID=112:#Representation=10:#Language=af \
-i udp://225.225.225.225:5001/:gpac:listen=true:tsprobe=true:#ASID=100:#Representation=10:#Language=am \
-i udp://225.225.225.225:5003/:gpac:listen=true:tsprobe=true:#ASID=199:#Representation=10:#Language=arn \
-i udp://225.225.225.225:5005/:gpac:listen=true:tsprobe=true:#ASID=105 \

```
When we try to do the same using only one UDP stream with multiple tracks each track appears in the playlist but no as adaptation set but as representations, which is undesired since dash starts switching between these representations. This second scenario can be reproduced using the following commands:
gStreamer:
```bash

Is there a way to assigns a different adaptation set Id to each track?

We are building an LL HLS origin and we have noticed GPAC sometimes sends several times an HTTP PUT request to the origin, for the same segment/part name, when we are in `llhls=sf` mode.
## GPAC command
```
gpac -i udp://239.0.0.1:1234 reframer:rt=on -o http://http_origin:80/live/upload/playlist.mpd:gpac:dual:buf=-100:segdur=3.0:cdur=0.2:asto=2.8:llhls=sf:hlsc=true:cmaf=cmfc:dmode=dynamic:profile=dashif.ll:utcs=https://time.akamai.com/?iso:hmode=push:template=segment_$(openssl rand -hex 5):hmode=push
```
## FFMPEG command
```
ffmpeg -re -f lavfi -i testsrc=size=1280x720:rate=25 -f lavfi -i sine=frequency=1000 -f mpegts -vcodec libx264 -acodec aac -profile:v high444 -b:v 2000k -maxrate 2000k -bufsize 2000k -r:v 25 -g 50 udp://239.0.0.1:1234
```
## Steps to reproduce
Repository with all the artifacts to reproduce the case: https://github.com/estigma88/gpac_experiments/tree/main/6-udp_mpegts_duplicated_segm.
The following are the steps:
1. Navigate to the `6-udp_mpegts_duplicated_segm` folder
2. Run the docker compose for few minutes: `docker-compose up`
3. Stop the docker compose; `docker-compose down`
4. Two new folders should show up: `content` (media folder) and `logs` (nginx logs)
5. Run the python script to find the HTTP PUT duplicates in the nginx access logs: `python3 findmediaduplicates.py` . The following is an output example:
```
playlist.mpd
playlist.m3u8
playlist_1.m3u8
playlist_2.m3u8
segment_890df68f91_track257_2.m4s
segment_890df68f91_track256_2.m4s
segment_890df68f91_track256_3.m4s
segment_890df68f91_track257_3.m4s
segment_890df68f91_track257_4.m4s
segment_890df68f91_track256_4.m4s
segment_890df68f91_track256_5.m4s
segment_890df68f91_track257_5.m4s
```
6. Open the access log in logs/access.log, and try to find one of above duplicates, you will see two places: before the first part is transferred, and before the last part is transferred:

```
## Questions
1. What is being sent in the second HTTP PUT, before the last part? and why?
2. Is this happening only for full segments or also for parts? we have seen this happening sometimes for parts, but hard to reproduce
3. Also, we have seen GPAC resending a whole segment and its parts, is that common? When can that happen?
4. What should the origin behavior be in those cases? override the previous segment? ignore?
Any help will be much appreciated.

"gpac",
"gpac"
] | Description
The [gpac VobSub parser](https://github.com/gpac/gpac/blob/ec145e7fc36597ffdbc0bae924de261324ded1ca/src/media_tools/vobsub.c#L254-L453) takes a FILE* handle and attempts to load the information from that file into its memory.
The main focus of this report revolves around [the first few lines of the function](https://github.com/gpac/gpac/blob/f54c70d041448bddc2083a63d4241a2bd63f688e/src/media_tools/vobsub.c#L256-L275) and how they make some assumptions about buffer sizes that allows for an out-of-bounds read:
```
char strbuf[256];
char *str, *pos, *entry;
for (line = 0; !error && gf_fgets(strbuf, sizeof(strbuf), file); line++) // Read up to 256 bytes into strbuf
{
str = strtrim(strbuf);
if (line == 0) // Conditional for if this is the first line of the VobSub file:
{
char *buf = "VobSub index file, v";
pos = strstr(str, buf); // Find where 'buf' appears in 'str'
if (pos == NULL || sscanf(pos + strlen(buf), "%d", version) != 1 || *version > VOBSUBIDXVER) // Read and check the version integer
{
error = 1;
continue;
}
}
...
}
```
In this extract, a buffer of 256 bytes is allocated on the stack, and a maximum of 256 bytes are read into that buffer from a file.
From there, the buffer is 'trimmed', which seems to leading whitespace on each side of the buffer with null bytes (although on the 'left' side of the buffer, its index is simply incremented) - this 'cleaned' version is stored in str.
Later, a string search (strstr) occurs for the text "VobSub index file, v" in the buffer. This string search assumes that the buffer (str) is null-terminated to avoid searching past the 256-byte boundary.
Furthermore, an (optionally signed) integer is read from the end of the "VobSub index file, v" position in the buffer - this makes the assumption that the string ("VobSub index file, v") occurs at least four (implementation-specific, but usually four) bytes before the end of the buffer.
Both of the aforementioned assumptions are incorrect when strbuf is non-null upon initialization, and more favourably for an attacker, whenever the contents of strbuf fill the buffer exactly. At which point, there is no guarantee of a null-terminator and such read/write attempts may impact other arbitrary data.
Proof of Concept
This proof of concept code shows that an element past the end of the strbuf array can be read by filling the aforementioned buffer.
```
#include <ctype.h>
#include <string.h>
#include <stdio.h>
#define MIN(A, B) (A > B ? B : A)
char* strltrim(char* str) {
if (str == NULL) {
return NULL;
}
while (*str) {
if (!isspace(*str)) {
return str;
}
str++;
}
return str;
}
char* strrtrim(char* str) {
char *end;
if (str == NULL) {
return NULL;
}
end = str + strlen(str);
while (end-- > str) {
if (!isspace(*end)) {
return str;
}
*end = '\0';
}
return str;
}
char* strtrim(char* data) {
return strltrim(strrtrim(data));
}
#define VOBSUBIDXVER 7
int run_iter(char* const strbuf) {
char* const str = strtrim(strbuf);
const char* buf = "VobSub index file, v";
char* const pos = strstr(str, buf);
int ver = 0;
int* version = &ver;
if (pos == NULL || sscanf(pos + strlen(buf), "%d", version) != 1 || *version > VOBSUBIDXVER) {
return -1; // Should hit this if there was no overflow situation.
}
return 1;
}
int main(void) {
char strbuf[256 + 1];
memset(strbuf, 0x01, 256); // Where test_data will fall within.
strbuf[256 /* Out of gpac's boundary */] = VOBSUBIDXVER + 0x37 /* 0x37 is ASCII for '0' */;
// test_data = ('.' * 236) + "VobSub index file, v"
const char* const test_data = "............................................................................................................................................................................................................................................VobSub index file, v";
// Using MIN() here as a sanity check to ensure that we aren't writing over the 256 buffer that would be present in gpac.
memcpy(strbuf, test_data, MIN(strlen(test_data), 256));
printf("run_iter(...): '%d'\n", run_iter(strbuf));
return 1;
}
```
Impact
This report and the proof-of-concept therein have focused almost exclusively on two memory violations within the first 20 lines of vobsub_read_idx; the scope of this issue actually includes the entire function which repeatedly assumes that the 256-byte buffer is terminated. Such areas have been included in the 'Occurances' section.
Fixing this vulnerability will be extremely simple. By (optionally increasing the size of strbuf by a single byte and then) setting strbuf[sizeof(strbuf) - 1] = 0x00 only including sizeof(strbuf) - 1 as the length in the call to gf_fgets, the buffer will always be null-terminated.
I'm happy to fork and make a pull request with this patch however I wouldn't want to create a public fork too early in the event that it could disclose information regarding the issue to third parties.
Thanks for the great work you all do with gpac!

"gpac",
"gpac"
] | Hi,
I want to extract the frame of a tiled mp4 using the Python API of GPAC, then process and render using OpenCV. Can you please tell me how to do it? I tried the custom_sink.py, but it throws errors. I also looked into this https://github.com/gpac/gpac/issues/1761 issue.
When I ran the custom_sink.py on a tiled HEVC from Kvazaar, it ran and showed packets like this.
```

PCK Prop: 1280, 720
```
Can you tell me what these arrays imply? I guess these are frame data. But how can I make OpenCV read them?
But for tiled mp4 videos, it gives this error:
```
Exception ignored on calling ctypes callback function: <function filter_cbk_configure at 0x7f4f818325e0>
Traceback (most recent call last):

] | Hi, I'm using kvazaar for a university project and I'm having a little problem. I would appreciate if someone help me to solve it. I am working with five different qualities of the same video (480p,720p,1080p,2k,4k)
I have generated the segments (for all the qualitis) and stored them on a server. I am working with WSL2 and I have the server in windows.
So to play the content, I use the following command gpac -gui http://192.168.1.221/TFG/dash_tiled.mpd#VR
The problem is that I get a black screen. I have captured the traffic with wireshark and I have obtained two different cases. Sometimes only the "init" files are requested and the segments are not requested. And in other cases everything seems to be fine. The client requests the "init" files and segments and the server provides them I have tried to reproduce the 5 mpds of the 5 qualities and they all work correctly. The problem is the mpd with more than one representation.
I attach the mpd and the wireshark captures that proves that sometimes the traffic is correct and the client dosen't request the segments

] | 1.Do you have an API that can tell me how long it takes to assemble a picture using HEVC tiles based on MPEG-DASH?
2.Can I switch the fs.http_max_bitrate limit during the process when using ABS? For example, can I switch from a limit of 7500 to 37500 after 20 seconds?
3.Is it possible to change the download queue for HEVC tiles based on MPEG-DASH to simultaneously download segments of the MPD? If so, how can I do this with a call in Python?

] | Hello, I am trying to configure some Atmos files so they can play properly on my iPhone. Figured out what was causing the issue was the Complexity Index in the Atmos mediainfo was labeled "Not Present/16" instead of just "16." Tested two different files with MP4Box and one file that didn't say "Not Present" was recognized as ATMOS while the other that listed it didn't. How can I change the complexity index to get rid of "Not Present?"

I want to detect individual frames from the GPAC's tile-encoded mp4 output bitstream. I could not get any suitable command argument for it.

This saves only 10 frames, but the command keeps running on the terminal. Ideally, it should stop once 10 frames are encoded and saved.

```
gpac -i video://:fmt=x11grab:framerate=30:video_size=1280x720:dev=: --kvazaar-params=tiles=4x4,slices=tiles,mv-constraint=frametilemargin,input-fps=30,input-res=1280x720 enc:c=libkvazaar tilesplit @ -o named_pipe1:ext=mp4:frag
```
It throws a warning as below
```
[MP4Mux] Cannot add track to already finalized movie in fragmented file, will request a new muxer for that track
No filter chain found for PID video1_tile1 in filter mp4mx to any loaded filters - NOT CONNECTED
```
The generated output file has only one stream, which should be 17 for a 4x4 tiled video, right?
I'm not able to use fragmented mode properly.

Description: Debian GNU/Linux bookworm/sid
Version
I checked against the latest release as of 05/29/23 the current master branch at commit 4f810869b06b5d7b0cb73d166864dfb4b1e900f6 .
Description
This AddressSanitizer output is indicating a read on an unknown address 0x8. This exception occurred in the function dasher_configure_pid at line 1418 in the file dasher.c. This root cause of this error is that the function call to gf_odf_avc_cfg_read on the line line 1418 just before the call to gf_list_get can return 0/NULL. This value is set to the variable avccfg and is then dereferenced like this:
avccfg->sequenceParameterSets
The fix is to properly check the return value whenever gf_odf_avc_cfg_read is called, or change said function to exit cleanly with an error if it is fatal.
GF_AVCConfig* avccfg = gf_odf_avc_cfg_read(dsi->value.data.ptr, dsi->value.data.size);
//The provided testcase causes avccfg to equal 0.
GF_NALUFFParam *sl = (GF_NALUFFParam *)gf_list_get(avccfg->sequenceParameterSets, 0); // the deref that causes the asan output is here

] | When generating multiple Low Latency HLS (LL-HLS) manifest files of different qualities from an ongoing RTMP stream within a Kubernetes (K8s) pod, several issues arise.
Locally, the LL-HLS files play fine, with minor audio synchronization and multiple audio playback issues. However, the main problem occurs when attempting to scale the stream through a Content Delivery Network (CDN), causing the playback of the stream to freeze.
Here are some cases I have tried:
- Locally:
- LL-HLS files play fine, but encounter occasional audio synchronization and multiple audio playback issues.
- When utilizing Ngrok or an Nginx web server:
- Playback of LL-HLS files is smooth, but audio errors occur.
In both the above cases, the desired delay of 4-6 seconds was achieved successfully.
- Within a Docker container:
- The same issues experienced in the K8s environment persist.
- LL-HLS files exhibit freezing playback when scaled through a CDN.
My intention is to produce the LL-HLS stream from within a K8s pod and distribute it through a CDN. Is that possible?
Has anyone faced this sort of issues?
I would really appreciate your help!

Environment
Distributor ID: Debian
Description: Debian GNU/Linux bookworm/sid
Release: n/a
Codename: bookworm
Version
I checked against the latest release as of 05/18/23 the current master branch at commit a6ae93532ea5615c876c81a6580badbfa01d4383 .
Description
This AddressSanitizer output is indicating that an out of bounds read occurred in the function gf_filter_get_stats at line 4149 in the file filter_session.c. A bit of debugging leads me to think that the loop at line line 4131 is improperly bounded since at the crash, the loop iterator i equals 0xffff4f07
for (i=0; i<f->num_input_pids; i++)

Some demuxers read only the first `avcC`, so the part of the video stream is unplayable because references to a missing PPS.
Note 1: Only first `avc1` contains `btrt`.
Note 2: I also see the following warning in the output `[AVC|H264] xPS changed but could not flush frames before signaling state change !`.

] | Hi @jeanlf ,
I'd like to continue the thread at #2466 since I made some tests using the httpout filter as you suggested for the server.
I still continue to get Network unreachable and I tried several files two of them are using different codec for H.265
This time I have the logs on both sides server and dasher on uploading.
Here there is the description of the logs and video files used:
1) _gpacLogs.zip_ contains the followings logs file:
- gpacServer.log: is the log on server started with the command defined #2466
- uploadLiveStreaming.log: is the log of client uploading the video stream to Gpac Server
- uploadToCustomServer.log: is the log of client uploading the video stream to my customization of node_gpac
2) Video Source: is Big Buck Bunny 4K video downloaded from [here](https://download.blender.org/demo/movies/BBB/). It is one of the sample available on [Kodi](https://kodi.wiki/view/Samples). It was used to generate all logs
In addition, because hls.js doesn't support the particular codec of the video, I used VLC as player and I was able to watch a few seconds of the video using my customization of the server, instead with gpac server VLC was buffering indefinitely.
I hope we can understand the issues in some ways

Most SONY cameras records PCM_S16BE 48000Hz, 2 channels with the audio tag `twos`.
SONY FX3 records PCM_S24BE 48000Hz, 2 channels with the audio tag `ipcm`.
I also saw some files with the audio tag `lpcm`.
mp4box from GPAC v2.0 worked with PCM 16-bit audio:
`mp4box -add video.h264 -add audio.wav -new mux.mp4`
produces a correct and playable MP4 file (audio.wav is PCM_S16LE, 48000Hz, 2 channels).
mp4box from GPAC v2.2+ (including the latest) creates a MP4 file with the correct audio handler `twos` but the audio data is missing at all. `stco`, `stsz`, etc. are empty for the audio track.
Note most players are used the audio stream for sync with the timeline, so the resulting file is not playable. It is possible only to seek and see a static picture.

In GPAC, we treat all NAL types indicating IDR/BLA with decodable leading pictures as SAP2 if and only if the following picture has a poc less than the sap picture, otherwise we use SAP1.
We do this because many encoders use decodable leading pictures NAL type signaling when they in fact use simply IDRs. Not doing so would end up having SAP2 indicated in e.g. DASH manifest, which may break validation by some players.
Note that we don't change the NAL type, just the SAP type.

I have created a couple of test uncompressed files with Y Cb Cr components (no subsampling). Converting those to PNG, JPEG or YUV fails with unable to convert caps.
A simple way to reproduce this is:
```
#gpac uncvg:c=Y,U,V:fps=0 -o gpac_yuv.heif
$ ../../gpac/bin/gcc/gpac -i gpac_yuv.heif -o out.yuv
No suitable filter to adapt caps between pid gpac_yuv.heif in filter uncvdec to filter writegen, disconnecting pid!

```
In addition, trying with PNG will segfault:
```
$ ../../gpac/bin/gcc/gpac -i gpac_yuv.heif -o out.png
No suitable filter to adapt caps between pid gpac_yuv.heif in filter uncvdec to filter encpng:1.6.37, disconnecting pid!
Segmentation fault (core dumped)
```

"gpac",
"gpac"
] | I would like to understand if GPAC supports HLS [RFC8216bis-3](https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis-13), since I'm trying to use gpac for implementing LLHLS Origin PUSH setup and I'm dealing with several problems which I'm going to report below. I would like to know better how GPAC should work.
GPAC 2.2 Command on Ubuntu 20.04: `gpac -graph -r -stats -i video.mp4 reframer:rt=on -o http://localhost:8000/live.m3u8:gpac:hmode=push:segdur=6:cdur=1:profile=live:dmode=dynamic:hmode=push:llhls=br -no-h2`
Client Player: [Hls.js](https://hlsjs.video-dev.org/demo/)
1) Is there any support to Playlist Delta Update? It looks that gpac sends media playlists every time that they are changed, is that right? If it is so, should I overwrite the playlists on server side?
2) In both RFC8216 and RFC8216bis-13, there is a specification about EXT-X-TARGETDURATION, which MUST NOT change (see [General Server Responsabilities](https://datatracker.ietf.org/doc/html/rfc8216#section-6.2.1). Why does gpac send a new media playlist with EXT-X-TARGETDURATION=10 altough in the previous requests it was 6 as I declared into the command? (See files in the attachments)
3) If you look at the version 15 of live1.m3u8 in the attachments, you can observe the following aspects:
> EXT-X-TARGETDURATION=11 (still changing before previous one)
> All media segments previous at _video_dash_track1_9.m4s_ are not present anymore
> There are some media segments with subsegments and other without.
Does all look correct for you?
4) Client player interrups the playback because it makes a request for a segment that has not available in the server side yet. Why does it happen? Should player follow and make request according to what is written inside media playlists?
5) Gpac prints a lot of error messages regarding Network Unreachable and some issues on dasher filter.
In the attachments you can find:
- _playlists.zip_: contains some of the most important versions of playlists exchanged between gpac and server.
- _gpacLiveStreamingHls.pcap_: contains the whole network trace of all packets exchanged between gpac application and server both of them running on the same host. Server uses tcp port 8000. It was made with _tcpdump_
- _gpacLogsScreenshot.png_: logs printed by the command above
Please let me know, if you need more information about the test that I run.

"gpac",
"gpac"
] | I am trying to generate **LL-HLS** files from an **RTMP Stream**, but I couldn't find any examples on how to generate _multiple qualities_.
It works perfectly fine, meaning the LL-HLS .m3u8 files are generated, but only a master file and two separated files.
Current Command:
`gpac -i rtmp://[server]:1935/live/[key] reframer:rt=on -o res/live.m3u8:segdur=2:cdur=0.5:profile=live:dmode=dynamic:llhls=sf:ts`
Output Tree:
res/
-- list of segments.ts
-- live.m3u8
-- live_1.m3u8
-- live_2.m3u8
Is there such a command or parameters to specify different output qualities, like res/720p, res/1080p, res/480p ... ?

It's removing the generated m4s files for some reason.
Streaming the file with MP4Box -dash 1000 -frag 1000 -rap -segment-name segment_ "sample.mp4" works fine but I wanna do it dynamic so I can push new mp4 files as they arrive at the server to the live stream (like this issue: https://github.com/gpac/gpac/issues/1252).

I'm trying to build an MP4Box command to set the channel labels of a multi-track MOV where every audio track has just one channel.
The problem I'm facing is that for some reason FFmpeg labels the left surround / right surround tracks as "Bl / Br" when they should be "Ls / Rs", at least according to mediainfo. I want MP4Box to set these channel labels for me but don't see anything in the documentation about channel labels. Suggestions?

I'm using GPAC as an RTMP server to mux the incoming stream to produce a DASH stream. The producer is a GStreamer pipeline pushing the content to GPAC. When GStreamer starts pushing, GPAC segfaults with little information about the error:

While the problem might be in the configuration of the [`x264enc`](https://gstreamer.freedesktop.org/documentation/x264/index.html?gi-language=c#x264enc), the segfault in GPAC's side makes it difficult to spot the problem.
You could use the docker-compose of the repo above to reproduce the issue:
```shell
# build containers
docker build -t gpac_experiments:http_origin -f containers/http_origin.dockerfile .
docker build -t gpac_experiments:gstreamer -f containers/gstreamer.dockerfile .
docker build -t gpac_experiments:gpac -f containers/gpac.dockerfile .
# run the example
cd 0-dash
docker-compose up
```

Hi,
I tried the following command in order to use HLS protocol for making onDemand streaming:
`gpac -r -graph -stats -i video.mp4 -o http://localhost:8000/live.m3u8:gpac:hmode=push:profile=onDemand -no-h2`
I implemented a node.js server for storing all segments in a particular folder, but VLC Player and several web player using hls.js are not able to play the video. It looks like that the fragments are not created correctly.
You can see the error showed in [hls.js Demo]( https://hlsjs.video-dev.org/demo/) in the attached images.
In addition, I observed that m3u8 file was wrong since it shows that there are Indpendent Segments although the command require onDemand profile.
According to [Apple HLS Specification](https://developer.apple.com/documentation/http_live_streaming/example_playlists_for_http_live_streaming/video_on_demand_playlist_construction), the content of the m3u8 file should be:
`#EXTM3U
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-TARGETDURATION:10
#EXT-X-VERSION:4
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:10.0,

#EXTINF:10.0,
http://example.com/movie1/fileSequenceC.ts
#EXTINF:9.0,
http://example.com/movie1/fileSequenceD.ts
#EXT-X-ENDLIST`
Instead the output generated by the command below is that one
`#EXTM3U
#EXT-X-VERSION:6
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:BANDWIDTH=534662,CODECS="avc1.4D401F,mp4a.40.2",RESOLUTION=1280x720,FRAME-RATE=25,AUDIO="audio2"

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio2",NAME="2",LANGUAGE="eng",AUTOSELECT=YES,URI="live_2.m3u8",CHANNELS="2"`
Is there something wrong in the command?

`MP4Box -add video.ts:tc=50/1,11,09,59,07 -splitx 0.93:60.93 -new out.mp4`
instead of producing:
`out.mp4`
produces:
`out_0.93_60.93.mp4` (or `out_.mp4` with single underscore character suffix if error occurs).
How can I force MP4Box to name the output file `out.mp4`?
Currently it breaks my script which expects the name to be always `out.mp4`.
I can't get the name from the output, it doesn't say it:
```
IsoMedia import video.ts - track ID 33 - Video (size 1920 x 1080)
IsoMedia import video.ts - track ID 34 - Audio (SR 48000 - 2 channels)
splitting: file 1 done
```
I don't see the name with a `-v` flag either.
I've tested it with the latest GPAC 2.2 and with the older 1.0.1-rev1.0.1+dfsg1-4+deb11u1, both versions create changed name.

] | Hey, I'm writing an MP4 muxer right now and MP4Box has been instrumental in figuring out things I'm doing wrong. I've managed to create a file that satisfies MP4Box, as well as plays back in things like ffmpeg, VLC, Chromium and Firefox. However, the file fails to play in QuickTime and Windows' Movies&TV - which leads me to believe something is still fishy with my file. However, after hours of comparing the bytes and values of the boxes of my file and an ffmpeg-fixed version of it, I can't really find anything.
Here's the file (audio-only):
https://user-images.githubusercontent.com/1696106/230993312-b78ca932-5db7-45c2-8b13-af20b9ffab1d.mp4
And this is the MP4Box `-info` output:
```

```
Now, in a way yes, I'm asking for somebody from this community to lend me a helping hand - maybe it'll be easy for them to spot what's wrong with the file. But, more importantly, maybe MP4Box can grow from this and improve its troubleshooting even more.

I produce 4 qualities, with commands similar to this:
```

-r 60 -x264opts 'keyint=120:min-keyint=120:no-scenecut' \
-movflags faststart \
-an -c:v libx264 \
-preset fast \
-profile:v main out-480.mp4
```
I generate 360p, 480p, 720p and 1080p.
Then I use `MP4Box` like this:
```
MP4Box -dash 2000 -frag 2000 -rap -fps 60 -profile onDemand \
encoded/out-1080.mp4'#video:id=1080p' \
encoded/out-720.mp4'#video:id=720p' \
encoded/out-480.mp4'#video:id=480p' \
encoded/out-360.mp4'#video:id=360p' \
encoded/out.m4a'#audio:id=Main:role=main' \
-out index.mpd
```
With short videos it works, but with longer videos it takes a very long time. I am trying with a 6 hour video, and it's been running for 48h now.
When I start it, it goes up at a decent pace, for example, I just launched it:
```
Dashing P1 AS#1.1(V) seg #398 0.20s (10.15 %) AS#1.2(V) seg #398 0.22s (10.83 %) AS#1.3(V) seg #398 0.22s (10.83 %) AS#1.4(V) seg #398 0.18s (9.17 %) AS#2.1(A) seg #398 0.22s (10.93 %) / MPD 794.22s 4 %
```
and it's at 4% in like a minute.
But after a while it seems to go slower and slower until it takes an hour for a single percent. (this is a general observation, I have not measured it)
When it is running, I see one CPU at 100%.
Is it normal? Can I do something to make it faster? I have a threadripper and a lot of memory (256GB) in my system, can I do anything to leverage that?

- [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 ...).
Essentially the issue only seems to happen with 7.1 audio muxed with mp4box. If you play the file and do not touch seek at all, the audio will stay in sync. If you pause/seek (forwards/backwards) the audio will either not play for a while or once it does it's very very out of sync.
This only seems to be present when the 7.1 audio is encoded with Dolby Encoding Engine.
If i encode the audio with ffmpeg, the issue is not present in the mp4.
If i mux the DEE audio with the video into mp4 with ffmpeg the issue is not present.
If i mux the DEE audio with the video into mkv with mkvtoolnix the issue is not present.
The issue only seems to happen with audio encoded with dolby encoding engine, and muxed with mp4box.
Here is a zip file with my sample examples, using a DTS:X Demo video.
I have provided a sample of the audio encoded to eac3 with both ffmpeg and dolby encoding engine.
If you play the DTSX Gravity Encoded - ffmpeg.mp4 in VLC media player you should see that it plays back fine even when skipping around the video.
If you play the DTSX Gravity Encoded - DEE.mp4 in VLC media player, you should see that it initially plays back fine but as soon as you start skipping around the video the audio becomes out of sync.

I tested it on Windows 11 with the same build and the same sample, and no errors were observed on Windows 11. It worked normally. My guess is that my Windows 11 computer has much better specs, so it seemed to be doing its job normally and complete before the progress bar prematurely displayed Killed.
In the case of Linux, the specs were very poor so the progress bar was very slow, and MP4Box seemed to have reached the limit of its patience and decided to stop working, imo. It's like a hungry customer leaving a restaurant without waiting for the food to be ready.

```
A heap buffer overflow vulnerability has been detected in the GPAC multimedia framework. The issue occurs during the processing of AVI input files, leading to a potential compromise of the application's memory and possible remote code execution.
The vulnerability is caused by an incorrect boundary check when copying memory using the memcpy function (__interceptor_memcpy). This results in a read operation of size 352,321,536 bytes at address 0x625000018bc6, which is located at the edge of the allocated memory region.
The overflow occurs within the following GPAC library functions:
avi_parse_input_file
AVI_open_input_file
avidmx_process
gf_filter_process_task
gf_fs_thread_proc
gf_fs_run
gf_dasher_process
Additionally, the MP4Box application is also affected, as it relies on the vulnerable GPAC library functions.

```
A heap use-after-free vulnerability has been discovered in GPAC MP4Box's ogg_stream_clear function when processing OGG files. The vulnerability occurs due to improper handling of memory allocations and deallocations while processing OGG files. This leads to the use of previously freed memory, causing a potential risk of memory corruption, crashes, or other undefined behaviors.
Reproduce : ./bin/gcc/MP4Box -dash 1000 POC
Impact
An attacker who can successfully exploit this vulnerability could potentially execute arbitrary code in the context of the application, leading to a compromise of the system where the vulnerable software is installed. Additionally, the attacker could use this vulnerability to cause a denial of service (DoS) by crashing the application or making it unresponsive. This vulnerability poses a significant risk to the confidentiality, integrity, and availability of systems running the affected software.

This has a slight de-synchronization between audio and video in the generated assets.
On the other hand this works fine:
```
MP4Box -new sintel-video.mp4 -add sintel-video.vvc:fps=24
MP4Box -dash 2700 -rap -profile onDemand -segment-name '$File$_mp4_$FS$$Number$' -out sintel_mp4.mpd sintel-video.mp4 sintel-audio.aac
```
Looking at the dumped xml from the generated video mp4 shows, that in the case with the raw bitstream the `CTSOffset` values are calculated incorrectly:
```
<TrackRunBox Size="532" Type="trun" Version="1" Flags="2561" Specification="p12" Container="traf" SampleCount="64" DataOffset="665">
<TrackRunEntry Size="6006" CTSOffset="31"/>
<TrackRunEntry Size="2782" CTSOffset="14"/>
<TrackRunEntry Size="1562" CTSOffset="5"/>
<TrackRunEntry Size="649" CTSOffset="0"/>
<TrackRunEntry Size="327" CTSOffset="-3"/>
<TrackRunEntry Size="154" CTSOffset="-5"/>
<TrackRunEntry Size="151" CTSOffset="-4"/>
<TrackRunEntry Size="340" CTSOffset="-2"/>
<TrackRunEntry Size="150" CTSOffset="-4"/>
<TrackRunEntry Size="164" CTSOffset="-3"/>
...
```
In contrast, this is what it looks like, when adding the video as an MP4 file:
```
<TrackRunBox Size="532" Type="trun" Version="0" Flags="2561" Specification="p12" Container="traf" SampleCount="64" DataOffset="640">
<TrackRunEntry Size="6006" CTSOffset="36"/>
<TrackRunEntry Size="2782" CTSOffset="19"/>
<TrackRunEntry Size="1562" CTSOffset="10"/>
<TrackRunEntry Size="649" CTSOffset="5"/>
<TrackRunEntry Size="327" CTSOffset="2"/>
<TrackRunEntry Size="154" CTSOffset="0"/>
<TrackRunEntry Size="151" CTSOffset="1"/>
<TrackRunEntry Size="340" CTSOffset="3"/>
<TrackRunEntry Size="150" CTSOffset="1"/>
<TrackRunEntry Size="164" CTSOffset="2"/>
...
```
It looks like the decoding delay is not taken into account correctly.

Using the `test5.mkv` sample file from the following URL: <https://github.com/ietf-wg-cellar/matroska-test-files/blob/master/test_files/test5.mkv>, I'm running GPAC like follows:
```bash
gpac -graph \
'src=/tmp/test5.mkv' \
'rfsrt:SID=#PID=5' @ 'tx3g2ttml:FID=subs' \
'dst=/output/out.mpd:dmode=static:SID=#PID=0,#PID=1,subs'
```
I'm expecting GPAC to create a DASH stream with a manifest file at `/output/out.mpd`, that includes the Video stream (PID 0), the audio stream (PID 1), and the French subtitles (PID 5) in `ttml` format, each embed in their respective fragmented mp4 containers. But instead I'm getting:

Platform:
Windows 10, mp4box version 2.2-rev0-gab012bbf-master
There are 2x PPS NAL units in a video encoding made by nVidia's NVEnc when weighted prediction is turned on. One PPS is for normal operation and the other PPS contains the weighted prediction information. When extracting the raw video stream with `mp4box -raw 1 <file>`, only the first (non-weighted prediction) PPS is extracted, leaving the weighted pred frames un-decodable. A sample encoding has been [uploaded here](https://www.mediafire.com/file/5thmnhuor68f02y/DHBSPan_nVidia_A4000_VBR_POnly_QtrPass_60fGoP_WPred-short.mp4/file).
Also, when you inspect the file with `mp4box -info`, it gives these details for Track 1:
```Parameter Sets: 1 VPS 1 SPS 1 PPS```
It should say:
```Parameter Sets: 1 VPS 1 SPS 2 PPS```
The attached encoding has the first PPS at offset 0x089 and the second one at offset 0x094.

Dash segments don't have an equal duration in `SIDX.duration` and `mdat.duration(samples*dur)` fields. **Should SIDX and mdat fragment chunk durations match?**
Things go even more wrong after encryption, **first** `cenc/v1/1.m4s ` file is `SIDX.dur=3.76s, mdat=3.84s !!!` values.
Encoding target is 3,84s segments (input aac 48Khz/h264 25fps, gop 96 frames), this should give 100% align video+audio segment durations.

I built it from source by following this [instructions](https://github.com/gpac/gpac/wiki/GPAC-Build-Guide-for-OSX).
I'm attempting to convert an mp4 file into a playlist and segment files using the LLHLS protocol as the primary format. Due to my work requirements, I need to output both multiplexed and non-multiplexed segment files separately (not necessarily simultaneously), but no matter how I adjust the command, I am unable to output multiplexed segment files. I have tried referring to a similar issue #1775 and several wiki explanations ([Dasher](https://github.com/gpac/gpac/wiki/dasher), [HLS](https://github.com/gpac/gpac/wiki/hls#hls-with-one-file-per-segment), [LLHLS](https://github.com/gpac/gpac/wiki/LL-HLS#hls-low-latency-setup), [Dash Transcoding](https://github.com/gpac/gpac/wiki/dash_transcoding#same-resolution), etc.), but still can't get it to work. What I want to achieve is an output in LLHLS protocol that includes only one variant m3u8 file, one init file, and segment and part files for a single audio and video stream (it's okay if a master m3u8 file is also generated). Is this a bug or is there a specific part of the command I need to adjust?
The command I used is:
```bash
gpac -i "input.mp4:#Representation=main" \
"reframer:rt=on" @ \
"ffsws:osize=640x360" @ \
"enc:c=avc:fintra=2" @2 \

-o "index.m3u8:segdur=5:cdur=0.5:profile=live:dmode=dynamic:llhls=sf:tsb=-1:append" \
-graph
```
This command will generate these files in my output folder.

It seems that two streams are being outputted at the (PID manifest_m3u8) fout location.
Here is the output of `gpac -i "input.mp4" inspect` command (I can upload the file to Dropbox if needed).
```

I have a basic understanding of audio and video concepts and streaming protocols, but I am extremely unfamiliar with transcoding. Please let me know if there are any errors or omissions in my understanding.
