Fixed #2625
ld: warning: ignoring duplicate libraries: '-lbz2', '-lcaca', '-lfreetype', '-lnghttp2', '-lpng16', '-lpthread', '-lz'
ld: Undefined symbols:
_memrchr, referenced from:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
---chatgpt answer---
If you are trying to build on Mac, the function `memrchr` is not available in the macOS libc. This function is a GNU extension and is not present on all systems, including macOS.
You will need to either conditionally use an alternative function when building on Mac, or provide your own implementation of `memrchr`.
Here's an example of a simple `memrchr` implementation:
```c
void *memrchr(const void *s, int c, size_t n) {
const unsigned char *cp;
if (n != 0) {
cp = (unsigned char *)s + n;
do {
if (*(--cp) == (unsigned char)c)
return (void *)cp;
} while (--n != 0);
}
return NULL;
}
```
You can include this function in your code when you're building on macOS. Be sure to wrap it with an `#ifdef` check to ensure it's only used when `memrchr` is not available:
```c
#ifndef HAVE_MEMRCHR
void *memrchr(const void *s, int c, size_t n) {
/* ... function code ... */
}
#endif
```
Then, in your build system, ensure that `HAVE_MEMRCHR` is defined when building on systems that have `memrchr`.

Detailed guidelines: http://gpac.io/bug-reporting/
I'm currently trying to work in a multitrack playlist hls packager, but gpac is not aplying the group correctly to each track
```bash
gpac \
-i udp://0.0.0.0:5010/:gpac:listen=true:tsprobe=true:#HLSGroup=LL_V_Group:#Representation=LL_V_Track:#HLSMExt=DEFAULT=YES reframer:rt=on \

-i udp://0.0.0.0:6012/:gpac:listen=true:tsprobe=true:#HLSGroup=Aug2_A_Group:#Representation=Aug2_A_Track reframer:rt=on \
-o http://origin:8081/live/upload/playlist.m3u8:gpac:buf=-150:ll_part_hb=-1:ll_rend_rep=true:hls_ap=true:seg_sync=no:segdur=6.0:cdur=0.5:llhls=sf:hlsc=true:cmaf=cmf2:dmode=dynamic:pssh=v:hmode=push
```
The generated playlist looks something like this...
```
#EXTM3U
#EXT-X-VERSION:6
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="Aug1_V_Group",DEFAULT=NO,NAME="Aug1_V_Track",URI="playlist_1.m3u8"
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="Aug2_V_Group",DEFAULT=NO,NAME="Aug2_V_Track",URI="playlist_2.m3u8"
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="LL_V_Group",DEFAULT=YES,NAME="LL_V_Track",URI="playlist_3.m3u8"
#EXT-X-STREAM-INF:BANDWIDTH=1024443,CODECS="mp4a.40.2,avc1.4D401F",RESOLUTION=1280x720,VIDEO="Aug1_V_Group"
playlist_4.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1024430,CODECS="mp4a.40.2,avc1.4D401F",RESOLUTION=1280x720,VIDEO="Aug1_V_Group"
playlist_5.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1024443,CODECS="mp4a.40.2,avc1.4D401F",RESOLUTION=1280x720,VIDEO="Aug1_V_Group"
playlist_6.m3u8
```
Is possible to see that the generated EXT-X-STREAM-INF is not pointing to the seted VIDEO with the HLSGroup, this happens also when the primary is the VIDEO (hls_ap=false) the AUDIO attribute in the EXT-X-STREAM-INF is pointing to the same audio and not the one setted in the HLSGroup
am I using GPAC wrong? could this be a bug?

@jeanlf in the last issue (https://github.com/gpac/gpac/issues/2488)
you mentioned
"
Here's what I checked:
dashing using 15s segments instead of 30s: playback until end OK
dashing video only with 30s segments: playback until end OK
dashing audio only with 30s segments: playback until end OK
The segment durations in 30s Audio+Video and 30s VideoOnly are the same, and the last segments are correct.
I think that's a WMP bug, there's not much we can do here.
"
I have set the segments to 29s 20s 15s , playback is OK.

] | Is there a way to command line combine multiple video files into one while keeping the file actually playable and adding black bars to vertical clips?
This functionality kind of works when using MP4Joiner, but it is fairly slow to add files and it crashes very often when trying to combine 100+ files or some files that are broken for whatever playback reason.
The output is also often choppy and video files become garbled at points and playback is not possible. (MPC HC but eventually planning to upload to youtube unlisted)
However the addition of black bars is excellent and from my task manager i can see many files are being re-encoded with ffmpeg while the process is going on.
When using MP4Box, the videos combine, but playback is not possible a lot of the time and vertical clips are streched to fit the first horizontal size.
My command is this - i've tried some variations and removal of bs-switching as well.
`$command = '"C:\Program Files (x86)\MP4Tools\bin\MP4Box" -bs-switching merge -force-cat' ; (Get-ChildItem *.mp4 | sort { [regex]::Replace($_.Name, '\d+', { $args[0].Value.PadLeft(20) }) } ) | foreach { $command += " -cat $_" } ; $command += " combined.mp4" ;$command ; cmd /c $command`
(i have also tried the newest GPAC mp4box.exe files)
With this i get a full list of mp4's and they are all -cat'ed into the command.
Here are some sample files and the mp4 that is created when i combine with the mp4box command.
https://www.dropbox.com/scl/fo/auvvmk03oeoq2k7w175qv/h?rlkey=387jb5ccu9b6vvdv3k55qd1c9&dl=0
In these test files the mp4joiner file is also quite broken after combining. But the mp4box combined file handles vertical even worse.
How could i re-encode these to make the files actually play? I cant find a way right now, but it would be awesome to be able to combine my live photo clips to a movie. | combining multiple small video files (iphone live photo clips) into one file - horizontal and vertical files | https://api.github.com/repos/gpac/gpac/issues/2630/comments | 4 | 2023-10-11T07:52:49Z | 2023-10-13T09:09:09Z | https://github.com/gpac/gpac/issues/2630 | 1,937,091,378 | 2,630 |

[
"gpac",
"gpac"
] | I'm trying to build a custom filter that will push Transport Stream segments to GPAC. My filter will connect to an `m2tsdmx` for demuxing the data and continuing the processing.
My filter creates a PID with the same properties as the [TS muxer](https://github.com/gpac/gpac/blob/master/src/filters/mux_ts.c#L1144) and the filter capabilities are set similarly:
```c
CAP_UINT(GF_CAPS_OUTPUT_STATIC, GF_PROP_PID_STREAM_TYPE, GF_STREAM_FILE),
CAP_STRING(GF_CAPS_OUTPUT_STATIC, GF_PROP_PID_FILE_EXT, M2TS_FILE_EXTS),
CAP_STRING(GF_CAPS_OUTPUT_STATIC, GF_PROP_PID_MIME, M2TS_MIMES),
```
## The problem
After building an instance of my filter (`tssource`) and one of `m2tsdmx` and connecting them together using `gf_filter_set_source` (which return OK error code), the filters still are not connected.
### Questions
* Is there a way to diagnose why the `gf_filter_set_source` failed at creating the links between two filters? Currently, `gf_filter_set_source` returns OK, so I'm not sure where else to look for information.
* What should be the Filter caps, and PID properties needed to be able to feed an instance of `m2tsdmx`?

Command used to mux:
```bash
mp4box -add pdcut.mkv -brand mp42 -ab isom -ab dby1 -new pdcut.mp4

Playing the video file the first subtitle is kinda lost, the second is used in the 1st position, third sub goes to 2nd position. Seems one of the additional menu tracks has subtitle 1 content. Pretty wild.
Doing a video import only (or all/some tracks with `#ID` imports) also has side effects:
Command used to mux:
```bash
mp4box -add pdcut.mkv#video -brand mp42 -ab isom -ab dby1 -new pdcut.mp4
```
Output tracks:

Until a possible fix, is there a way to ignore the menu track when importing mkv files this way?
For now the only workaround I found is to demux the tracks from the mkv file and use those which is a bit of an overhead.
To reproduce this seems any mkv file will do which has some subs and a menu. | mp4box: subtitle and menu tracks goes wrong/mixed when muxing from mkv to mp4 | https://api.github.com/repos/gpac/gpac/issues/2607/comments | 8 | 2023-10-01T17:09:36Z | 2023-10-06T10:55:13Z | https://github.com/gpac/gpac/issues/2607 | 1,920,869,964 | 2,607 |

Description
This AddressSanitizer output is indicating an OOB read of invalid heap memory. This exception occurred in the function chnl_box_size at [line 12758](https://github.com/gpac/gpac/blob/master/src/isomedia/box_code_base.c#L12758) in the file src/isomedia/box_code_base.c. This error is caused because the variable ptr->layout.channels_count can be larger than the actual number of layouts in ptr->layout.layouts[] and larger than the maximum number of layouts, which is 64. The struct that defines the maximum layouts is in the file include/gpac/isomedia.h at [lines 1464-1486](https://github.com/gpac/gpac/blob/master/include/gpac/isomedia.h#L1464-L1486).
src/isomedia/box_code_base.c:[lines 12756-12760](https://github.com/gpac/gpac/blob/master/src/isomedia/box_code_base.c#L12756-L12760)
for (i=0; i<ptr->layout.channels_count; i++) {
s->size+=1;
if (ptr->layout.layouts[i].position==126)
s->size+=3;
}
Specifically this is the line that causes the asan to trigger when i > 64.

#Additional potential crash sites
I do not have a POC file to exercise these code sites, but they follow a similar logic.
https://github.com/gpac/gpac/blob/master/src/isomedia/box_dump.c#L6882-L6888
https://github.com/gpac/gpac/blob/master/src/isomedia/box_code_base.c#L12687-L12697
Impact
An OOB read on the heap can potentially cause a crash or information disclosure in some cases. Could be leveraged with other vulnerabilities for a more serious impact.
Occurrences
box_code_base.c L12687-L12697
This instance in the code is fairly similar to the crash site. Not verified via a POC.
box_code_base.c L12756-L12760
This is where my crash was that caused ASAN.
box_dump.c L6882-L6888
This instance in the code is very similar to the crash site. Not verified via a POC.

When using the C-api, there is a small inconsistency in the `gf_fs_load_filter` when passing an empty string as filter name.
```c
#include <stdio.h>
#include <gpac/filters.h>
int main(int argc, const char** argv) {
GF_FilterSession *session = gf_fs_new_defaults(0u);
if (session == NULL)
{
fprintf(stderr, "Failed to create GPAC session\n");
return EXIT_FAILURE;
}
GF_Err gf_err = GF_OK;
GF_Filter *filter_ptr = gf_fs_load_filter(session, "", &gf_err);
const char* err_str = gf_error_to_string(gf_err);
printf("Error code %d: %s\n", gf_err, err_str);
if (filter_ptr == NULL) {
printf("Filter ptr NULL\n");
} else {
printf("Filter loaded\n");
}
return EXIT_SUCCESS;
}
```
The code above prints:
```
Error code 0: No Error
Filter ptr NULL
```
With an extra log line `Missing filter name in` produced by gpac logs.
Instead, if I run the code above with `GF_Filter *filter_ptr = gf_fs_load_filter(session, "some_unknown_filter", &gf_err);`, the output is:
```
Error code -11: Filter not found for the desired type
Filter ptr NULL

] | Question regarding file size reduction and bitrate reduction when muxing video and audio using MP4Box
I have got some jerky motion video only when play with QuickTime Player. They can be fixed by demuxing and re-muxing using MP4Box.
Today, I got one video both file size and bitrate are reduced even though just demuxing and re-muxing using MP4Box. (File size was reduced to about 68% of original video, Bitrate was reduced to about 67% of original video)
After processing, I mean demuxing and re-muxing, the video seems to play without any problem. I feel suspition about file size and bitrate are reduced such a big amount without re-encoding. Could you explain me such a thing is possible or not?

I would like to express my sincere gratitude for providing us with the exceptional open-source software, GPAC. Currently, I am utilizing MP4Box for image encapsulation.
Here are the steps I follow to process the images:
1. First, I use ffmpeg to pad the images to m512 x n512 dimensions. The command is as follows:
`ffmpeg -i input.png -vf "pad=4096:3072:220:240" pad.png`
2.Next, I utilize the kvazaar encoder to encode the resized images into HEVC bitstreams with a tile size of 512x512. Additionally, I encapsulate the bitstreams into HEIF format images. The command I am using is:
`MP4Box -add-image pad.png:@enc:c=libkvazaar::kvazaar-params=tiles=8x6,slices=tiles,mv-constraint=frametilemargin:@tilesplit -new pad.heic`
I have encountered a few issues during this process and would greatly appreciate your assistance. My first question is regarding the usage of MP4Box to execute ffmpeg commands, so that I can accomplish the image padding, transcoding, and HEIF encapsulation steps with a single MP4Box command, like follows:
` MP4Box -add-image input.png:@ffavf:f=pad=w=4096=h=3072:@enc:c=libkvazaar::kvazaar-params=tiles=8x6,slices=tiles,mv-constraint=frametilemargin:@tilesplit -new pad.heic
`
I tried the command mentioned above, but I didn't get any output.

hello
I'm trying to play the mpd file that tiled 360 video using gpac's sgaze option.
However, it does not run normally. There is no change depending on the mouse.
There are two types of image quality: low-definition and high-definition, and we generated one mpd file by packaging it in mp4box.
Here's the code I used.
In addition, may I know what is the minimum value of mbuffer?
1. gpac -gui dash_file.mpd#vr --mbuffer=500 --skip_lqt --sgaze=true
Any help would be appreciated.

I referred to [wiki](https://github.com/gpac/gpac/wiki/GPAC-Build-Guide-for-Linux#mp4box-only) and this [issue](https://github.com/gpac/gpac/issues/2045), it looks like currently gpac does not support static compilation with `asan`, so I tried build the gpac latest commit (`16c2fce`) with `./configure --enable-sanitizer && make -j` to build a dynamic binary. However, the compilation failed due to undefined reference to `__asan_init`.
Detailed fail results are sth like the following:

I'd like to know how to build the latest version of gpac with `asan`?
May you help on this? Thank you. | ASAN build error | https://api.github.com/repos/gpac/gpac/issues/2587/comments | 5 | 2023-09-04T12:48:31Z | 2024-01-15T12:24:52Z | https://github.com/gpac/gpac/issues/2587 | 1,880,216,006 | 2,587 |

**Is it possible to generate dash `trun.version=1 (negative composite offset)` for audio segments?**
Video segments use `trun.version=1` format but never able to do it on audio segments.
Validators may output warnings if version=1 is not used.
Mp4box can write `trun.version=1` for video segments but no audio segments.
```

```
Ffmpeg can write `trun.version=1` for video and audio segments.
(output folders `./0/, ./1/` must exist)

] | MP4 file format appears to support a default flag on audio tracks as well as subtitle tracks, although not all MP4 players respect this setting, many simply pick the track with the highest ID.
To ensure maximum compatibility, it would be nice if MP4Box could allow setting this flag. FFMPEG currently allows it with the `-disposition:a:1 default` flag, so that may be a useful reference for how it's being done.
- [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/

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
I'm working integrating `libgpac` into another framework. For now, I'm trying to build simple applications to understand the basics of gpac. The simplest I came out with is one that creates a file using the `fout` filter and dumps some bytes to disk. The bytes comes from outside the gpac filter session.
```c
#include <stdio.h>
#include <stdlib.h>
#include <gpac/filters.h>
/// @brief Print the input and output PIDs of a filter
/// @param filter
static void print_filter(GF_Filter *filter) {
// iterate over filter input PIDs
u32 input_pid_count = gf_filter_get_ipid_count(filter);

Running the code prints:
```
filter dst: from_gpac.ts
is source : false
is sink : true

```
I have problems figuring out how to get input PID from the `fout` filter to feed the buffer to store in the file.
The closest issue to mine is https://github.com/gpac/gpac/issues/2190 which suggests the creation of custom filters for handling communication in and out of the gpac filter graph.
Is there another example I could look at?

When integrating `libgpac` into other code systems, it can be useful to have some form of identity/passthrough filter that lets any data pass through the input PID to the output without modification.
Is there any existing filter that implements such behavior? Otherwise, I'm keen to contribute such a filter. | Identity/Passthrough filter | https://api.github.com/repos/gpac/gpac/issues/2565/comments | 9 | 2023-08-28T14:24:24Z | 2023-10-05T21:41:54Z | https://github.com/gpac/gpac/issues/2565 | 1,869,872,221 | 2,565 |

] | I was waiting for the resolution of https://github.com/gpac/gpac/issues/2526 but since there has been no progress for some time, I would also like to ask about preparation of FairPlay DRM content in mpeg-ts container with GPAC. Trying it with the latest 2.3-DEV-rev479-g941a0891-master downloaded today.
Using simple command `gpac -i source.mp4 cecrypt:cfile=drm.xml -o playlist.m3u8:segdur=3:profile=live:template=seg:muxtype=ts` where HLS SAES-based drm.xml consists of
```
<?xml version="1.0" encoding="UTF-8"?>
<GPACDRM type="HLS SAES">
<DRMInfo type="pssh" version="1" >
<BS ID128="94CE86FB07FF4F43ADB893D2FA968CA2" />
<BS value="1" bits="32"/>
<BS ID128="ecae683de67a9c182f54ea704b4b5961" />
</DRMInfo>
<CrypTrack isEncrypted="1" constant_IV_size="16" constant_IV="0x712ecac8f88a44114cdd0f65f3812c60" saiSavedBox="senc">
<key KID="0xecae683de67a9c182f54ea704b4b5961" value="0x{128-bit key}" hlsInfo='URI="skd://ecae683d-e67a-9c18-2f54-ea704b4b5961",KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1"'/>
</CrypTrack>
</GPACDRM>
```
does not generate proper sample-AES encrypted content usable with FairPlay DRM. Safari and Apple native players consider the HLS content corrupted and unplayable, it's not even recognized after loading the first TS segment, the error occurs immediately and no license is even requested.
I cannot claim that the following is everything causing the issue, there might be more but it might be a good start. What I see is:
- The TS segments are missing private_data_indicator according to https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/HLS_Sample_Encryption/TransportStreamSignaling/TransportStreamSignaling.html
- The m3u8 playlists must be `EXT-X-VERSION: 5` as minimum when using `METHOD=SAMPLE-AES`, `KEYFORMAT` and `KEYFORMATVERSIONS` attributes required for FairPlay, see https://developer.apple.com/documentation/http-live-streaming/about-the-ext-x-version-tag
- When preparing FairPlay content, the `IV` atribute should not be usually part of the `EXT-X-KEY` tag. IV is negotiated within the FairPlay license itself at least from my own experience. Some toggle might be needed for this, whether to add it to the playlist or not.
When I was playing with the fmp4 counterpart by using the same drm.xml but just replacing type `"HLS SAES"` with `"cbcs"` and not using `muxtype=ts` in the commandline, it was faring a bit better. EXT-X-VERSION in m3u8 playlists was automatically set to 6, it was recognizable as a whole as "usable" content, however, only audio track was decryptable, video track remained scrambled. I assume the reason being the warning message from GPAC while packaging: `Using cbcs pattern mode on-video track is disabled in GPAC, using whole-block full encryption`. Not sure why the exception in GPAC for video tracks. Correctly working audio in this example seems to prove that the pattern mode is the way to go.
All in all, can you please comment whether my configuration should yield the expected results or are there errors on my side somewhere? Searching for https://github.com/gpac/gpac/issues?q=fairplay , reading wiki and examples in the repo did not provide complete answers.
Otherwise could you please try to get GPAC suite closer to expectations of Apple? | FairPlay content in mpeg-ts based HLS | https://api.github.com/repos/gpac/gpac/issues/2564/comments | 1 | 2023-08-25T15:23:02Z | 2024-05-31T14:43:01Z | https://github.com/gpac/gpac/issues/2564 | 1,867,244,982 | 2,564 |

] | - [x] I looked for a similar issue and couldn't find any.
- [x] I tried with the latest version of GPAC build from source
- [x] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...).
### Platform
Mint 21.2 based on Ubuntu 22.04 jammy. Box is a BXNUC10i7FNH2 from 2022. 32G ram, no swap, <33% used.
### Background (skippable):
I was late updating Mint 20.3 to 21.x... Afterwards, one of my scripts failed. The upgrade had replaced MP4Box 0.5 with Ubuntu 22.04's default 2.0 build. Building from a fresh clone (less than an hour ago) - same. After some trial and error I found it crashes on the `name` tag (_after_ successfully applying any other tags in the same command), and after a lot more trial and error I found it crashes only when the 'alias' is used, but not when the unaliased tag name is used.
### Sample bash log
```

### Sample file
(my own, hereby licensed public domain - but repoducible using any other I've found):
https://www.mediafire.com/file/19bjtrey0xbi4s6/MVI_3398.mp4/file
### Tests I tried
Tried with a swap partition, too, as the messages could fit a malloc problem - no change.
Different files and/or command lines give different messages - sorry can't repro an example right now.
`MP4Box - GPAC version 0.5.2-DEV-revVersion: 0.5.2-426-gc5ad4e4+dfsg5-5` extracted from timeshift - runs fine on the same platform (after making its libraries loadable through LD_LIBRARY_PATH).
`MP4Box - GPAC version 2.3-DEV-rev476-gebfad0b53-master` freshly built as '--static-bin' using *only* unaltered Ubuntu repo sources and tools (I reverted a younger cmake for this) - same crash.
Other string tag aliases I tried do not crash (encodingTool, sortName, albumArtist).
The `artwork` alias does not crash but does not produce the same file as `cover` either (not recognized by MediaInfo as Cover:Yes but as binary blob - `cover` seems off in other ways, such as not being cumulative). | Using 'name' alias crashes a MP4Box -itags command | https://api.github.com/repos/gpac/gpac/issues/2560/comments | 5 | 2023-08-15T09:22:44Z | 2023-08-15T17:25:55Z | https://github.com/gpac/gpac/issues/2560 | 1,851,143,379 | 2,560 |

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
Is posible to add the `NAME` property to the `#EXT-X-MEDIA` tag when using HLS multivariant playlist?
I'm using the command
```
gpac \
-i udp://225.225.225.225:5000/:gpac:listen=true:tsprobe=true:#Representation=default \
-i udp://225.225.225.225:5001/:gpac:listen=true:tsprobe=true:#Representation=player-stats \

```
But the playlist generated is:
```
#EXTM3U
#EXT-X-VERSION:6
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:BANDWIDTH=1650000,CODECS="avc1.42C028,mp4a.40.2",RESOLUTION=1920x1080,FRAME-RATE=30,AUDIO="audio2"

#EXT-X-STREAM-INF:BANDWIDTH=308000,CODECS="avc1.42C028,mp4a.40.2",RESOLUTION=1920x1080,FRAME-RATE=30,AUDIO="audio2"
playlist_2.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=330000,CODECS="avc1.42C028,mp4a.40.2",RESOLUTION=1920x1080,FRAME-RATE=30,AUDIO="audio2"
playlist_3.m3u8
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio2",NAME="audio",AUTOSELECT=YES,URI="playlist_4.m3u8",CHANNELS="2"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio2",NAME="audio",AUTOSELECT=YES,URI="playlist_5.m3u8",CHANNELS="2"
```
Is possible to get the NAME property in the #EXT-X-STREAM-INF tags that contains the variant playlist?
There are examples for multivariant commands?
I'm looking for a playlist similar to this
```
#EXTM3U
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="low",NAME="66", DEFAULT=YES,URI="bunny/playlist_1.m3u8"
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="low",NAME="67",DEFAULT=NO,URI="cow/playlist_1.m3u8"
#EXT-X-STREAM-INF:BANDWIDTH=140800,RESOLUTION=1920x1080,CODECS="avc1.64002a,mp4a.40.2",VIDEO= "low"
bunny/playlist_1.m3u8
```
It is posible to manipulate the `#EXT-X-MEDIA` tag to use the video instead of the audio?

[
"gpac",
"gpac"
] | A similar issue to #1913 has been reintroduced in commit 796bb9e5e. When packaging a VVC bitstream, that contains IDRs with leading pictures, the CompositionOffset and thus the resulting CTS is calculated wrongly. CRAs with leading pictures seem to be fine.
I uploaded a raw bitstream (foreman.266) and resulting mp4 file (foreman.mp4) to the Mediafire share.
This is the command line for creating the MP4 file: `~/src/gpac/_build/bin/gcc/MP4Box -new foreman.mp4 -add foreman.266:fps=30`
and an excerpt from the `-diso` dump:
```
<CompositionOffsetBox Size="2416" Type="ctts" Version="0" Flags="0" Specification="p12" Container="stbl" EntryCount="300">

Hi, I want to convert a png/jpeg image to a heif image with a grid size of 512x512.
I was wondering if there was a cleaner way to convert png/jpeg images to heif images. Or can we use the gpac tool instead of ffmpeg to split png/jpeg images into 512x512 subgraphs and transcode them into hevc bitstreams.
Thanks!

] | For a university project I would like to use the HAS technique (obtaining different resolutions of the same video) and the tile-based streaming technique (dividing the video into different tiles, specifically using a 3x3 division).
I have generated the videos in different resolutions with the ffmpeg tool and later I have used this tutorial to perform the tiled streaming (https://github.com/gpac/gpac/wiki/Tiled-Streaming)
However, I have had problems with the reproduction of the content
I don't know if the problem is that both techniques cannot be used or if I should carry out another process.
I don't know if someone could help me solve this

Both commands seem to work fine, but I am facing some issues when I process the stream in a kubernetes pod.
I have to launch one pod for each quality otherwise the output playback won't be smooth, but even when I split each quality in a specific pod, I'm still facing lag issues qualities >= 720p.
Is there room for optimization in this command, if so: How can I optimize it? - Preferably one and multiple qualities | GPAC command - Optimization | https://api.github.com/repos/gpac/gpac/issues/2553/comments | 3 | 2023-08-09T10:38:51Z | 2023-09-04T07:54:21Z | https://github.com/gpac/gpac/issues/2553 | 1,842,956,655 | 2,553 |

"gpac",
"gpac"
] | Hello.
I've been playing with Dolby Vision in AV1 and currently MP4Box doesn't support parsing the metadata OBUs to set the config properly.
Currently when trying to mux with `MP4Box` we get this error:
```console
❯ MP4Box -add av1-dovi-reencode-small-rpu.ivf:dvp=f10.hdr10:hdr=none:stype=av01 -new av1-dovi-reencode-small-rpu.mp4
Track Importing AOM AV1 Video - Width 3840 Height 2014 FPS 24000/1001
DV profile can only be set on AVC or HEVC tracks
Failure while setting DV profile: Bad Parameter
Error importing av1-dovi-reencode-small-rpu.ivf:dvp=f10.hdr10:hdr=none:stype=av01: Bad Parameter
```
So far I've had to patch out the restriction and force the muxer to create the box.
The files work afterwards on the two devices I tested:
- LG OLED C2 with the internal player
- Amazon FireTV Stick 4K Max with ExoPlayer.
I'll leave an example file here, but I think it would essentially just require detecting the ITU-T T.35 metadata OBUs and check the first couple of bytes for Dolby Vision.
`rav1e` encoded IVF with small (< 256 bytes) RPU: https://www.mediafire.com/file/4ip5wknqecn43j8/av1-dovi-reencode-small-rpu.ivf/file
The files from https://github.com/gpac/gpac/issues/1925 also work after patching: [video_dovi_3840x2160_30fps_av01_10.mp4](https://github.com/gpac/gpac/assets/39477805/c23fe31c-bfcd-40f9-be38-58afb99bd148)
Some notes:
- The metadata OBU has `itu_t_t35_country_code` set to `0xB5`.
- The metadata OBU has `itu_t_t35_payload_bytes` starting with the following bytes:
- `0x00, 0x3B, 0x00, 0x00, 0x08, 0x00, 0x37, 0xCD, 0x08`
- The profile must be set to 10, otherwise demuxers assume HEVC.
- I'm not sure what the `dv_version` should be set, but `1.0` works fine. The old Dolby samples used `2.1` but the specification constrains `dv_version_major` to 1, and `dv_version_minor` to 0.
It might also be good to follow the [Dolby specification](https://dolby.my.salesforce.com/sfc/p/#700000009YuG/a/4u000000l6FB/076wHYEmyEfz09m0V1bo85_25hlUJjaiWTbzorNmYY4), but from my testing the `compatible_brands` are not necessary. | Add support for Dolby Vision dvvC box with AV1 video | https://api.github.com/repos/gpac/gpac/issues/2549/comments | 4 | 2023-08-07T13:16:17Z | 2023-09-28T16:32:22Z | https://github.com/gpac/gpac/issues/2549 | 1,839,439,145 | 2,549 |

Hi! I took the an example from https://github.com/gpac/gpac/wiki/dash_transcoding and changed it slightly:
```
gpac -i a.mp4 \
@ c=vp9:b=1m \
@@ c=vp9:b=200k \
@ @1 -o hls/master.m3u8:segdur=6
```
Everything works as expected, gpac creates two variants.
But if I try the same with an audio file:
```
gpac -i test.flac \
@ c=aac:b=64k \
@@ c=aac:b=96k \
@ @1 -o hls/master.m3u8:segdur=6
```
Then gpac will create three variants instead of the two that I expect.
With `-r -graph` it outputs:

What am I doing wrong?
I compiled gpac and ffmpeg myself inside a docker container with alpine linux. I tried both master with FFMPEG 6.0 and v2.2.1 with FFMPEG 5.1.3

Has there been any such change that deprecates this command? If so, how can I achieve the same/similar (or maybe better) result with the new release?

] | Hi there,
I'm working on a video streaming application where I want to stream tile-encoded bitstream from a server. The problem is at the receiver to render, I need to wait for all the moof packets to come. The size of moof varies depending on the frame type and scene, right?
Is there any way to fix the size of moof payloads so that fragments of the same size can be generated? By size, I mean the number of bytes in the fragment. I tried with `:cdur`, but it only fixes the time, not the size.
If this isn't possible, can I know the number of bytes dumped in each fragment when using `:frag`?

I have a project which is reading from RTSP streams and saves short 5-second segments to `mp4` files using FFmpeg and GStreamer.
I would like to be able to convert these `mp4` files to fragmented `fmp4` files in order to use them for HLS streaming.
My current pipeline looks like this:
- FFmpeg or GStreamer outputs short `mp4` files to a `/tmp` directory
- I run MP4Box on the file using this command:
```
MP4Box -dash 10000 -rap -frag-rap -segment-name output_ -out master.m3u8 /tmp/1690461275.mp4
```
- I then copy the resulting `.m4s` file to a new location which stores it for a longer period of time, and store the data from the `master_1.m3u8` file in a database so i can access the duration when generating a `.m3u8` file
I then have a webserver that serves the `.m4s` files
The users are suppose to be able to choose a timeframe of their liking, and i need to generate an `.m3u8` file on the fly which corresponds to the timeframe.
The problem that i am having is that no matter how i construct the `.m3u8` file, only the first segment in my playlist plays.
I think it might have something to do with my `MP4Box` command but i am not experienced enough in this field to tell for sure.
I would like to avoid running the MP4Box command when the user requests the stream to reduce delay, thats why i want convert the `mp4` files one by one.
Is it possible to make my usecase work using `MP4Box`?
TLDR: I want to convert `mp4` files to `m4s` files continuously and then create `m3u8` playlists on the fly.

Generation of uncompressed YUV 422 or 420 image with mixed interleave and tiling appears to work OK:
```sh
$ ./bin/gcc/gpac uncvg:vsize=20x12:c=Y8,U8,V8:tiles=2x2:interleave=mix:sampling=422:fps=0 -o ./uncompressed_yuv422_mix_tiled.heif

```
However viewing those with `gpac -gui` produces corrupted images, for tiles after the first tile.
Example (422):
I haven't done the work to determine whether the problem is on the encode or decode side, but a quick inspection of the generated file didn't identify any issue, so perhaps on the decode side.

It looks like `gpac -gui` (or perhaps the underlying GLSL library) can't handle the mixed interleave format.
Works well:
```
bradh@audax:~/coding/gpac$ ./bin/gcc/gpac uncvg:c=Y8,U8,V8:interleave=comp:sampling=422:fps=0 -o ./uncompressed_yuv_comp_422.heif

Using a current gpac (git 7c6cf9e9cafb4b34efcc30a578b62f453937abe9), with the uncvg plugin,
```
./bin/gcc/gpac uncvg:vsize=20x10:c=Y8,U8,V8:tiles=5x2:interleave=comp:sampling=420:fps=0 -o error.heif
```
produces repeated (10000+) errors of the form:
```
[uncvg] Error processing
Internal error in tile padding: remainder 31 is greater than tile size 30 tile start 0
```
I believe it is because the tile height needs to be a power of 2 for 420 to make sense, and in this case it isn't, so its an operator error. It might be possible to detect this invalid input / configuration rather than generate the errors though. | uncvg error handling for invalid tile size | https://api.github.com/repos/gpac/gpac/issues/2535/comments | 1 | 2023-07-24T10:47:36Z | 2023-07-24T10:56:29Z | https://github.com/gpac/gpac/issues/2535 | 1,818,160,050 | 2,535 |

] | Hello, I am doing a project at the Polytechnic University of Valencia (UPV) and for its realization, I need to access the GPAC player file and be able to access the properties that are shown in the player (such as the clock time shown in the attached image)
How could I do it?

] | Using this command (note I am using a slightly modified version of out_route.c to support updated and/or new ATSC 3.0 related features, built on the latest pull from github. Also note, I had the same issue with the non-modified out_route.c):
`gpac -i videos/world.mp4 reframer:rt=on dasher:profile=live:#ATSC3ShortServiceName=K16XX-D:#ATSC3MajorChannel=16:#ATSC3MinorChannel=1:#ATSC3ServiceCat=1:#ROUTEUpload=0.5:#ROUTECarousel=2 -o atsc://:ip=239.6.15.16:first_port=30000:bsid=1:llmode`
gpac is creating the ATSC3 LLS stream on 224.0.23.60 port 4937, as per the standard. However, it is not streaming the mp4 file. I can see port 30000 open in netstat as well as multicast group 239.6.15.16 active in netstat. tcpdump port 30000 shows no packets. tcpdump port 4937 shows packets and further analysis shows the LLS packets to be correct.
Only errors from gpac are:
`[Dasher] First CTS 5392800 in segment 60 drifting by 0.92 (more than half a segment duration) from segment time, consider reencoding or using segment timeline`
and
`[Dasher] Segment 67 duration 0.48 less than half DASH duration, consider reencoding or using segment timeline`
Would those errors cause DASH/ROUTE to not stream the mp4? Any other ideas on what might be the problem?
