```
"WebVTT (wvtt)" 3 .vtt files
```

The repro is provided in your dropbox at https://www.mediafire.com/view/qdy6a2zis7cq0s2/encode_rgba_version1.heif/file
It compresses well, so also attaching as zip.
[encode_rgba_version1.zip](https://github.com/gpac/gpac/files/14402358/encode_rgba_version1.zip)
I believe the test file is valid, and uses version 1 of the uncompressed configuration box.
This doesn't happen with my rgb3 equivalent test case - that renders correctly.

"gpac",
"gpac"
] | I'm trying to integrate `GF_FileIO` to my project and I've managed to read regular/static files but the same code fails for DASH input. It manages to get the manifest and then it tries to read the manifest again (then immediately closes it). Even if I force my code to recreate the request and feed a valid stream it fails immediately.
The error I'm getting:
```
[DASH] Error - cannot connect service: wrong file type gfio://0xf61b08

Actual test URL: https://livesim2.dashif.org/livesim2/mup_30/testpic_2s/Manifest.mpd
What I'm trying to understand is how does DASH/HLS is utilizing `GF_FileIO`. For regular files, it seems to be easy. Lifecycle seems to be like this `open->tell/eof->read->close`.

In memory-writing mode,
we use `gf_isom_open` using `"_gpac_isobmff_redirect"`
`gf_isom_set_write_callback`
after setting callback function
When exactly is the callback function called?
I think that `gf_isom_finalize` and `gf_isom_close_segment` call the callback function
And
If I want to call the callback function forcely, how to do that?
My plan is that
After making All segments, I calculate all duration of segments and allocate duration using
`gf_isom_set_movie_duration`
then I want to receive moov box data with a duration value assigned to it through callback function.
Can I use `on_last_block_start` to handle the above situation? | styp box is made twice | https://api.github.com/repos/gpac/gpac/issues/2757/comments | 2 | 2024-02-14T11:25:54Z | 2024-04-09T14:39:57Z | https://github.com/gpac/gpac/issues/2757 | 2,134,139,164 | 2,757 |

Using `iloc` with `construction_method == 2` appears to work OK for the case where `data_reference_index == 0`.
It doesn't work for the case where `data_reference_index` is 1, irrespective of whether the `DataEntryUrlBox` uses the flags `0x000001` method to point to the same file, or whether it uses a file. Instead, it just produces an empty black image.

I am trying to test a file that uses `imda`, which needs support for the `imdt` data reference. I see some work to add the `imda` container, but there does not appear to be `imdt` (under `dref`) support.
A couple of samples are attached as zip - the content should be the same in each, but the `_imda.heif` version is reported as invalid in gpac (and it could well be wrong as well).

I have a doubt, I think I remember reading how to do this in the past, but I can't remember if it was in gpac or the other known product (I'm not mentioning it here). The question is how to decrypt a specific segment, let's say, video_dash4.m4s if I have the xml I encrypted the full video with, and also (if needed) the dashinit.mp4 file
Then I want to encrypt it back (Only that segment)
Is that possible?
How?

Detailed guidelines: https://gpac.io/bug-reporting/
After dozens of hours of googling and thoroughly reading every piece of info, I'm still unable to start dynamic MPD broadcasting.
I've installed GPAC version 2.3-DEV-rev832-g799d9e547-master.
My OS Ubuntu 22
My goal is simple:
I getting short videofiles from time to time, and I want to combine them to "pseudo-stream".
My files have length exactly 30s, and I want to append them dynamically
```
gpac -i pl.m3u:ka=2000 -o live.mpd:dmode=dynamic
```
The playlist is very simple
```
##begin pl,m3u
../segment_0000.mp4
../segment_0001.mp4
##end playlist
```
What I get -- is a bunch of m4s files and few mp4 files, along with live.mpd file.
When i'm trying to play it, i have errors.
FFplay:
hundreds of such:
```
[dash @ 0x7f2228000cc0] Failed to open fragment of playlist f=0/0

### Description:
I spot a potential buffer overflow in command_line_parsing() function in broacaster.c:
https://github.com/gpac/gpac/blob/master/applications/testapps/broadcaster/broadcaster.c
### Details
```
static int command_line_parsing(int argc, const char** argv, unsigned short * tcp_port,
char *config_file, int *config_flag, unsigned short * mtu_size,
int * debug, u32 * socketType_for_updates)
{
int counter = 1;
if (argc < 2 || argc%2 != 1) {
fprintf(stderr, "Incorrect number of arguments, must be multiple of 2 (Please specify at least -f or -p arguments) !\n");
return -5;
}
for(counter = 1; counter < (argc - 1); counter+=2)
{
const char * a = argv[counter];
if (!strcmp("-p", a) || !strcmp("--port", a))
{
if (*config_flag)
{
printIncompatibleOptions();
return -2;
}
(*tcp_port) = port_from_string( argv[counter + 1] );
if (!(*tcp_port)) return -3;
}
else if (!strcmp("-f", a) || !strcmp("--file", a))
{
if (*tcp_port) {
printIncompatibleOptions();
return -2;
}
strcpy(config_file, argv[counter+1]); // Buffer overflow VULN
(*config_flag) = 1;
}
```
The function didn't check the length of **argv[counter+1]** and just copy into the **config_file** leading to buffer overflow.
### POC
I haven't reproduce this vulnerability.
### Impact

I tried to find a solution by following the code flow, but failed.
I am making segment files now.
and I want to allocate sample_duration value in trun box.
refer to below picture

I tried below code
```
// First, I do not use default value using force_traf_flags – if GF_TRUE, will ignore these default in each traf but will still write them in moov
if ((err = gf_isom_setup_track_fragment(file_ptr, track_id, sample_description_index, 0, 0, 0, 0, 0 , GF_TRUE)) != GF_OK)
{
fprintf(stderr, "Err Raised : gf_isom_setup_track_fragment: %d\n", err);
return -1;
}
// Second , add sample_duration in this function. I think that 1024 is trun sample_duration value
if ((err = gf_isom_fragment_add_sample(file_ptr, track_id, &iso_sample, sample_description_index, 1024, 0, 0, GF_FALSE)) != GF_OK)
{
fprintf(stderr, "Err raised : gf_isom_fragment_add_smple :%d\n", err);
return -1;
}
```
In result, If every sample has same sample_duration, tfdt default_sample_duration is added.
But when I use `gf_isom_fragment_add_sample` this function using different Duration argument (not fixed 1024)
sample_duration of trun box is added.

Result of looking at the code above
If first trun sample_duration and second sample_duration values are diffrent,
The code below works
```
if (!RunDur) trun->flags |= GF_ISOM_TRUN_DURATION;
```
https://github.com/gpac/gpac/blob/50c5c207595bb22f7f120572680971f0aae3c5fc/src/isomedia/movie_fragments.c#L678
I am curious as to why the trun sample_duration flag does not work when the trun sample_duration is the same.

--------------------
Hi all.
I'm working with 24/7 live streams, and trying to create a fMP4 segment from _another_ segment in _another_ format. The most common case would be to just encapsulate an existing webvtt file inside a non-yet-existing m4s/mp4 container file, but could actually be other formats as well (TTML maybe, or even TS). And that part works great by simply doing something like this:
`gpac -i segment_12345.vtt -o segment_12345.m4s`
However, I understand that file is actually not fMP4 but a full MP4 container for the original content. fMP4 requires also the init file with splitted data from the full container. And I didn't found a way to create it with the docs, neither for the command line tools or the Python bindings (which I would like to use).
I understand `dasher` filter allows me to create fMP4 output, but I was unable to do it with a single webvtt file as input. And the `mp4mx` filter (which I understand is the one instanced from that example command before) doesn't seem to have any fMP4 option. Of course I've tried other options I could find in the docs, but all without success so far.
So, I decided to just ask you people: *is there a way to create single-segment fMP4 output, init file included, from mp4-compatible input, using gpac?*
Thanks in advance. | Question: how to create single-segment fMP4 container output. | https://api.github.com/repos/gpac/gpac/issues/2730/comments | 1 | 2024-01-16T23:48:33Z | 2024-01-17T15:58:56Z | https://github.com/gpac/gpac/issues/2730 | 2,085,148,434 | 2,730 |

Hello, Thank you for your hard work. Sorry for asking a lot of questions recently.
I want to get earliest_presentation_time value in sidx box.
I tried to use below function
```
GF_EXPORT
GF_Err gf_isom_get_sidx_duration(GF_ISOFile *movie, u64 *sidx_dur, u32 *sidx_timescale)
{
u64 dur=0;
u32 i;
if (!movie || !movie->moov || !sidx_timescale || !sidx_dur)
return GF_BAD_PARAM;
if (!movie->main_sidx) return GF_NOT_SUPPORTED;
*sidx_timescale = movie->main_sidx->timescale;
for (i=0; i<movie->main_sidx->nb_refs; i++) {
dur += movie->main_sidx->refs[i].subsegment_duration;
}
*sidx_dur = dur;
return GF_OK;
}
```
My thought about this function,
this function only return GF_NOT_SUPPORTED
because movie->main_sidx never allocated.
I search main_sidx ,
I could not find using of main_sidx
how to get earliest_presentation_time value in sidx box ??
I am file open with callback mode using "_gpac_isobmff_redirect" and
making sidx box using ```gf`_isom_close_segment``` now.

When I write the segment files using callback function (```gf_isom_set_write_callback```)
First segment is made in the direction I want.
(```sidx styp moof mdat```)
Second segment, I want to make like below boxes
```styp moof mdat```. (without sidx)
but mdat comes separately when I close the segemnt ```gf_isom_close_segment```
comes first styp, moof, and next seperatly comes mdat box
Can’t we all make the box together? (styp, moof, mdat)
the only different thing is
I set the second argument to sidx to -1,
because I do not want to make sidx box
```
gf_isom_close_segment(file_ptr, -1, track_id, ref_track_decode_time, 0, 0, GF_FALSE, GF_FALSE, GF_FALSE, GF_FALSE, 0, 0, 0, NULL)

In this `else` block, the variable `payload`, which is involved in the `while` condition, is not updated. Consequently, we are stuck in an infinite while loop.
### Reproduction Scenario
1. The file used in this test:
https://github.com/gpac/gpac/assets/27826148/87c1287b-04a2-4bdb-8023-2256ff9d221d
2. Generating dash session:
```
gpac -i short.mp4 -o dash_session/live.mpd
```
3. Sending segments via ROUTE
```
gpac -i dash_session/live.mpd dashin:forward=mani -o route://234.1.1.1:1234/live.mpd -netcap=dst=route.gpc
```
4. Receiving the segments while patching the 13th byte of the first packet.
```
gpac -i route://234.1.1.1:1234/live.mpd -netcap=src=route.gpc,nrt,[s=1,o=12,v=0] inspect

"gpac",
"gpac"
] | I came across another issue with the CTS calculation for VVC bitstreams, where the IDR frames don't have POC 0.
Here you can find a sample bitstream: https://hege.cc/test_idr.vvc, which is created by VVenC v1.10.0 using more or less the default settings:
`vvencapp -q 28 --preset faster -rs 1 -rt idr -c yuv420 -t 12 --sdr sdr_709 -i /data/YUV/foreman_352x288.yuv --size 352x288 --fps 25 -o test_idr.vvc`
The POCs for the bitstream look like this:
```
POC 23 LId: 0 TId: 0 ( IDR_W_RADL, I-SLICE, QP 19 ) [DT 0.019] [L0] [L1] [:,(unk)]
POC 15 LId: 0 TId: 1 ( RADL, B-SLICE, QP 24 ) [DT 0.007] [L0 23] [L1 23c] [:,(unk)]
POC 7 LId: 0 TId: 2 ( RADL, B-SLICE, QP 25 ) [DT 0.007] [L0 15] [L1 15c] [:,(unk)]
POC 3 LId: 0 TId: 3 ( RADL, B-SLICE, QP 29 ) [DT 0.004] [L0 7] [L1 7c] [:,(unk)]
POC 1 LId: 0 TId: 4 ( RADL, B-SLICE, QP 30 ) [DT 0.004] [L0 3] [L1 3c] [:,(unk)]
POC 0 LId: 0 TId: 5 ( RADL, B-SLICE, QP 30 ) [DT 0.003] [L0 1] [L1 1c] [:,(unk)]
POC 2 LId: 0 TId: 5 ( RADL, B-SLICE, QP 32 ) [DT 0.002] [L0 1c] [L1 3] [:,(unk)]
POC 5 LId: 0 TId: 4 ( RADL, B-SLICE, QP 30 ) [DT 0.003] [L0 3c] [L1 7] [:,(unk)]
...
```
Muxing that file using latest master MP4Box `MP4Box -new test.mp4 -add test_idr.vvc:fps=25` gives the following CompositionOffsets:
```
> MP4Box -diso test.mp4 && grep CompositionOffsetEntry test_info.xml
<CompositionOffsetEntry CompositionOffset="7" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="5" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="10" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="5" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="2" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="0" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="1" SampleCount="1"/>
<CompositionOffsetEntry CompositionOffset="3" SampleCount="1"/>
...
```
The offsets should correctly be 28, 19, 10, 5, 2, 0, 1, 3.
There are more miscalculated CTSs later in the bit stream, when the POC wraps around.
I implemented a quick fix for this issue using a heuristic to probe for the minimum POC after an IDR. I will post it in a separate PR. With my fix MP4Box muxes the streams created by VVenC correctly, but a proper fix would probably involve parsing a significant portion of the SPS and then using the `dpb_max_num_reorder_pics` syntax element from the `dpb_parameters` structure to delay dispatching the packets instead of my heuristic. | Wrong CTS offset for non POC 0 IDR frames | https://api.github.com/repos/gpac/gpac/issues/2716/comments | 5 | 2024-01-08T15:35:39Z | 2024-01-29T16:05:42Z | https://github.com/gpac/gpac/issues/2716 | 2,070,701,977 | 2,716 |

In fact, video codecs depend from one quality to another sometimes.
Is there a way to do this using GPAC?
And if it is, how to perform DRM with different keys per each video track (quality) ?

I am gonna try making video fragment mp4.
I think that CTS_Offset is using for getting timestamp difference of decoding order.
PTS : 1 4 2 3
DTS : 1 2 3 4

when I muxing the video data using gpac, does gpac automatically input CTS_Offset?
or
do I input myself?
something like below,
```
iso_sample.IsRAP= RAP;
iso_sample.data = &buf[index];
iso_sample.dataLength = (frame_size - ADTS_HEADER_SIZE);
iso_sample.DTS = xxx;
iso_sample.CTS_Offset = xxx;
iso_sample.nb_pack = 0;

0000500 83 84 00 00 07 38 6d 64 61 74 ff 00 00 ff 00 00 >.....8mdat......<
0000520 ff 00 00 ff 00 00 00 80 00 00 80 00 00 80 00 00 >................<
0000540 80 00 00 00 ff 00 00 ff 00 00 ff 00 00 ff ff ff >................<
```
Those `0xff` after the start of `mdat` correspond to red values, and they occur every three bytes. Comparing that to Figure 12 (or Figure 13 for the storage view) in the FDIS, I would expect every four bytes.
Possibly related: When I view the resulting file in `gpac -gui`, I see corruption on the right pixels:
The effect is more visible if using tiles, as in:
`uncvg:sq=1:vsize=30x20:tiles=2x4:c=R8,G8,B8:sampling=none:interleave=pix:block_size=4:pixel_size=0:row_align=0:tile_align=0:fps=0`
where the first tile looks OK, but then its corrupted:
I don't see that visual corruption with `block_size=0`. | uncvg: block size appears to be ignored for pixel data | https://api.github.com/repos/gpac/gpac/issues/2707/comments | 1 | 2023-12-24T02:32:11Z | 2024-06-05T08:12:11Z | https://github.com/gpac/gpac/issues/2707 | 2,054,963,889 | 2,707 |

## Overview
Generating single channel files (e.g. palette or mono) results in corrupted results in gpac -gui for row and tile interleave mode.
## Test cases:
```
gpac uncvg:sq=1:vsize=30x20:tiles=2x4:c=M:sampling=none:interleave=row:block_size=0:row_align=0:tile_align=0:fps=0 -o test1.heif
gpac uncvg:sq=1:vsize=30x20:tiles=2x4:c=M:sampling=none:interleave=tile:block_size=0:row_align=0:tile_align=0:fps=0 -o test2.heif
gpac uncvg:sq=1:vsize=30x20:tiles=2x4:c=p:sampling=none:interleave=row:block_size=0:row_align=0:tile_align=0:fps=0 -o test3.heif

gpac uncvg:sq=1:vsize=30x20:c=M:sampling=none:interleave=row:block_size=0:row_align=0:tile_align=0:fps=0 -o test5.heif
gpac uncvg:sq=1:vsize=30x20:c=p:sampling=none:interleave=row:block_size=0:row_align=0:tile_align=0:fps=0 -o test6.heif
gpac uncvg:sq=1:vsize=30x20:c=x,M:sampling=none:interleave=row:block_size=0:row_align=0:tile_align=0:fps=0 -o test7.heif

Reproduce scenario:
1- i took the beepbop.mp4 (file attached to this issue) and generated a dash_session using following command:
```bash
gpac -i beepbop.mp4 -o dash_session/live.mpd
```
this generates the following files:
```bash
dash_session:

-rw-rw-r-- 1 1445 nov. 16 12:06 live.mpd
```
2- i saved a route session to route.gpc using the command:
```bash
gpac -i dash_session/live.mpd dashin:forward=mani -o route://234.1.1.1:1234/live.mpd -netcap-dst=route.gpc
```
3- i examined the content of the route.gpc by dumping the route_session using two methods , direcely dumping files with in_route module and using fout.
commands used:
```bash
gpac -i route://234.1.1.1:1234/live.mpd:gcache=false -netcap-src=route.gpc -o dash_session_via_route_fout/'$File$':dynext
```
```
gpac -i route://234.1.1.1:1234/live.mpd:odir=dash_session_via_route_in_dump/ -netcap-src=route.gpc
```
results :
```bash

```
we can see clearly that we systimatically drop the first segment of the track1 ( beepbop_dash_track1_1.m4s)
when I play the route session here is what i got:
1- i am omitting the verbose logs and only displaying what i think is relevant:
we receive the manifest file normally
[ROUTE] Service 1 got TSI 0 config package:
[ROUTE] Service 1 received MPD file live.mpd
we receive the first segment for track_2 normally
[ROUTE] Service 1 got file beepbop_dash_track2_1.m4s (TSI 20 TOI 1) size 7560 in 0 ms (320 bytes in 1 fragments)
[ROUTE] Pushing file beepbop_dash_track2_1.m4s to cache
[ROUTE] Service 1 got file beepbop_dash_track2_init.mp4 (TSI 20 TOI 4294967295) size 981 in 1 ms
[ROUTE] Pushing file beepbop_dash_track2_init.mp4 to cache
then we receive a bench of downloader fail to create service error for beepbop_dash_track1_init (more than two , i’m just omitting )
[Downloader] failed to create session for http://groute/service1/beepbop_dash_track1_init.mp4: Bad Parameter
[Downloader] failed to create session for http://groute/service1/beepbop_dash_track1_init.mp4: Bad Parameter
than we receive the second segments for the track1 beepbop_dash_track1_2.m4s.
[ROUTE] Pushing fragment from file beepbop_dash_track1_2.m4s to cache
[ROUTE] Service 1 got file beepbop_dash_track1_2.m4s (TSI 10 TOI 2) size 2335 in 620 ms
[ROUTE] Pushing file beepbop_dash_track1_2.m4s to cache
And the Dasher drop the first segment of track1:
[DASH] Error in downloading new segment http://groute/service1/beepbop_dash_track1_1.m4s: Bad Parameter
from now on all segments are received normally and the session is error free.
So to sum up when we create the route session from the dash session using netcap the route session isn’t able to correctly transport the first segment of the track1.

"gpac",
"gpac"
] | We are trying to stream LL-HLS content with gpac following the guidelines at gpac's [wiki](https://github.com/gpac/gpac/wiki/LL-HLS).
Our gpac build is a recent commit 6493680a0f9763149f467240b4eeafbe83ccb504 in the master branch. The content produced from gpac is served over an H2/3 web server ([h20](https://github.com/h2o/h2o)). We have used the following command to produce the HLS files:
```bash
segment_duration="3" #seconds
chunk_duration="2" #seconds - 0.56 -> 14 frames for 25 fps video
publish_mode="br" #br: byte range, sf: seperate file
gpac flist:srcs=$source:floop=-1 reframer:rt=on \
-o $manifest_file:rdirs=$output_dir:segdur=$segment_duration:cdur=$chunk_duration:profile=live:dmode=dynamic:llhls=br \
-logs=dash@inf
```
We are testing our stream using HLS.js's demo [page](https://hlsjs.video-dev.org/demo/).
We observed in our experiments that the playlist fetching interval is calculated as follows:
```c
interval = max(segment_duration/2, chunk_duration)
```
For instance, let the segment duration be 10 seconds, then the manifest file is fetched every five seconds. So, even if the part duration is one second and the target latency is three seconds, the latency cannot be lower than five seconds.
The playlist should be refetched for every part, right? Otherwise, the player will keep stalling.
Any comments? Are we missing something in our setup? | LL-HLS: Playlist fetching might be too slow | https://api.github.com/repos/gpac/gpac/issues/2700/comments | 15 | 2023-12-07T17:45:01Z | 2024-01-17T15:37:33Z | https://github.com/gpac/gpac/issues/2700 | 2,031,241,611 | 2,700 |

] | Is there any way of using gpac to input a video file and output different qualities, such as, 480p, 720p, 1080p, and forcing some of them to be always generated, such as 480p, and the others only if the video size is at least that size?
What I mean would be, if the input video is 720p, then only 480p and 720p should be generated, but not upscaling to 1080p.
Then, if a video is 240p, then upscale to 480p to have that size at least, and the rest should not be generated.
Among this, also do DRM accordingly

Detailed guidelines: http://gpac.io/bug-reporting/
I'm struggling with muxing dolby vision mkv's into mp4. Usual suspect is an LG tv (B9).
What I'v ran into is that for files that have multiple audio tracks the tv will only recognize dolby vision when playing with the first audio track for other tracks it falls back to HDR10. I'm completely puzzled by this as I don't see how the audio tracks relate to dolby vision. This behaviour is regardless of which track is actually used, if I add the audio streams in reversed order then still the first audio stream works correclty (originally last).
This issue doesn't seem to be specific to one file, all sources I tried (though limited, only 4 files) behaved the same. If I drop the second audio track then the file plays correctly, again regardless of which track is left.
I went through all the issues I found about dolby vision here and tried the varios options from there to avail.
The process I followed:
1. Extract HEVC and audio streams using ffmpeg
`ffmpeg -y -i /media/movie.mkv -map 0:1 -c:a:0 copy /media/audio_streams/Hungarian/0.hun.0.eac3 -map 0:2 -c:a:0 copy /media/audio_streams/English/1.eng.0.eac3 -map 0:0 -c:v:0 copy -bsf:v hevc_mp4toannexb /media/movie.hevc`
2. Extract DV RPU with [dovi_tool](https://github.com/quietvoid/dovi_tool)
`dovi_tool -c -m 2 extract-rpu /media/movie.hevc -o /media/movie.rpu.bin`
3. Downscale HEVC stream to 1080p with ffmpeg
`ffmpeg -y -hwaccel qsv -i /media/movie.hevc -map 0:0 -c:0 hevc_qsv -qp 25 -preset fast -pix_fmt + -x265-params hdr-opt=1:repeat-headers=1:colorprim=bt2020:range=limited:transfer=smpte2084:colormatrix=bt2020nc:range=limited:master-display='G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(10000000,0)':dolby-vision-profile=8.1:dolby-vision-rpu='/media/movie.rpu.bin' -vf scale_qsv=w=1920:h=1080 /media/movie-1080p.hevc`
4. Inject DV RPU to the downscaled stream with dovi_tool
`dovi_tool inject-rpu -i /media/movie-1080p.hevc --rpu-in /media/movie.rpu.bin -o /media/movie.rpu.hevc`
5. Package all streams into mp4 with MP4Box
`MP4Box -new -add /media/movie.rpu.hevc:dvp=f8.1.hdr10 -add /media/audio_streams/Hungarian/0.hun.0.eac3 -lang 2=hun -name 2=Hungarian -delay 2=0 -add /media/audio_streams/English/1.eng.0.eac3 -lang 3=eng -name 3=English -delay 3=0 -brand mp42 -ab isom -ab dby1 --force_dv /media/movie.mp4`
Altough I'm resizing the streams, it doesn't seem be the cause of this, if I skip that step the behaviour is still the same.
I'm using the following versions:
- MP4Box - 2.2.1-rev0-gb34e3851-release-2.2
- ffmpeg - 6.0-Jellyfin
- dovi_tool - 1.4.6 | Dolby Vision with multiple audio tracks | https://api.github.com/repos/gpac/gpac/issues/2694/comments | 10 | 2023-11-24T09:40:38Z | 2024-03-13T20:31:57Z | https://github.com/gpac/gpac/issues/2694 | 2,009,409,289 | 2,694 |

] | I hope to add a reference within an MP4/ISOBMFF file to a CTA-608/708 caption track contained in the video SEI side data, in accordance with ISO/IEC 14496-30:2018/Amendment 1:2022, [Part 30: Timed text and other visual overlays in ISOBMFF](https://www.iso.org/standard/82615.html).
- While the most recent version of ISO/IEC 14496-30 Amendment 1 is behind a paywall, the older version of the spec is public at [ISO/IEC 14496-30 PDAM1:2016 Support for CTA-708 captioning in SEI messages](https://mpeg.chiariglione.org/standards/mpeg-4/timed-text-and-other-visual-overlays-iso-base-media-file-format/text-isoiec-14496-0)
- ISOBMFF ISO/IEC 14496-30 Amendment 1 requires the use of the `csei` tag.
- CMAF ISO/IEC 23000-19:2020, Annex A.4/5, Table 11 [uses file brand](https://github.com/w3c/media-capabilities/issues/157#issuecomment-666600111) `ccea`, for CEA-608 and CEA-708 where "CEA-608 and CEA-708". Due to paywall, and older public version is available [here](https://mpeg.chiariglione.org/standards/mpeg-a/common-media-application-format/text-isoiec-cd-23000-19-common-media-application).
- The ISOBMFF `csei` data is analogous to the `caption_service_descriptor()` in ATSC A/65 MPEG-2 Transport Streams.
- This requirement is unrelated to the `clcp:c608` box in an Apple Quicktime MOV
CMAF ISO/IEC 23000-19 states that ISOBMFF ISO/IEC 14496-30 Amendment 1 is required.
> Signaling the presence of CEA-608/708 in SEI messages. The presence of CEA-608/708 data in SEI messages in a video track SHOULD be signaled as specified by MPEG-4 Part 30 Amendment 1.
ISO/IEC 14496-30 Amendment 1 states that referencing 608/708 data contained within the SEI data of a video track requires:
> #### Signalling the presence of CTA-708 in SEI messages
> The presence of CTA-708 data in SEI messages in a video track SHOULD be signaled by the presence of one or more Track boxes with Media Type `sbtl` with a Sample Entry codingname of `csei` and a track reference of type `csei` to the video track. This track SHALL NOT reference any media samples.
>
> Each track declares the language of one of the streams in the caption data by using an Extended Language Box (`elng`) in the Media Data Information Box (`mdia`).
>
> The `CEAServiceNumberBox` in the sample entry of each track identifies which service carries that language, and shall be present if more than one `csei` track is present. If this box is absent, `service_number` takes the default value of 1. The `csei` sample entry is derived from the PlainTextSampleEntry, with codingname equal `csei`. In the `CEAServiceNumberBox` there are two values from section 4.5 of the CEA708 specification: `is_708` reflects the TYPE OF SERVICE and is 1 for 708 and 0 for 608; `is_easy_reader` reflects the EASY READER value and is 1 for easy reader streams and 0 otherwise.
>
> The track header width and height give the display area for the stream; normally these are equal to the referenced video stream's width and height.
Most of the excellent MP4Box examples at https://github.com/gpac/gpac/wiki/Subtitling-with-GPAC relate to importing a subtitle track from an external file, rather than cross-referencing existing CTA-608/708 data contained in a video track's SEI messages. I have tried MP4Box's builtin `-add 'self':hdlr='sbtl':lang='eng'` options, but it looks like the standard command line tool does not support ISO/IEC 14496-30:2018/Amendment 1:2022.
I assume that since it is not directly supported through command-line options, I need to use a boxpatch/patch file. Assuming an MP4 containing a single video track, how can I use boxpatch/patch to add the following to the structure?
```
altBrand 'ccea' # For compatibility with CMAF, Appendix A.4/5, Table 11. (use alternate brand -ab ?)
'sbtl' > codingName 'csei' > trackReferenceType `csei`
'tkhd' > 'width'=720 'height'=480 # tkhd width/height for 608 data in NTSC
'mdia' > 'elng'='eng' # Extended Language Box
'CEAServiceNumberBox'
if 'is_708'=0 # analogous to ATSC A/65 digital_cc=0
# ATSC A/65 Line21 field number does not map to an ISOBMFF equivalent field.
if 'is_708'=1 # analogous to ATSC A/65 digital_cc=1
'service_number'=1 # analogous to ATSC A/65 caption_service_number
'is_easy_reader'=0 # analogous to ATSC A/65 easy_reader
# ATSC A/65 wide_screen does not map to an ISOBMFF equivalent field
```
In my case, I would like to add CTA-708, service number 1, easy_reader false.
As someone inexperienced with MP4Box patch files, I hope someone more familiar with box structures can point me in the right direction to how the above quotation from ISO/IEC 14496-30:2018/Amendment 1:2022 can be mapped within an MP4Box Patch File, for compliance with both ISO/IEC 14496-30:2018/Amendment 1:2022 and CMAF Appendix A.5 Table 11.
Unfortunately, I do not have the experience to understand which of the above boxes map to which nodes in a patch file in order to produce a compliant file. I hope that readers will appreciate that I have researched and cross-referenced the standards, however I am suffering from lack of experience with MP4Box patch file structure.
``` xml
$ cat "./patch.xml"
<GPACBOXES>
<box type="hdlr" action="add">
<!-- <box type="stbl" action="add"> -->
</box>
<box type="trak">
<box type="tkhd" action="add">
<!-- Track header fields go here -->
</box>
<box type="mdia">
<box type="mdhd" action="add">
<!-- Media header fields go here -->
</box>
<box type="minf">
<box type="stbl">
<box type="stsd" action="add">
<!-- Sample description fields go here -->
</box>
</box>
</box>
</box>
</box>
</GPACBOXES>
```
```
$ MP4Box -add "./infile.mp4" -patch "./patch.xml" -new "./outfile.mp4"
```
It seems that only a few ISOBMFF implementations utilize the standards-compliant boxes defined by ISOBMFF ISO/IEC 14496-30 Amendment 1 and CMAF ISO/IEC 23000-19:2020, Annex A.4/5, Table 11. Of course, in DASH/WAVE, it would be expected that the manifest would declare this same data to the player through the `<Accessibility schemeIdUri="urn:scte:dash:cc:cea-608:2015">` tag, but the Box data should still be accurate for unsegmented ISOBMFFs and standalone media segments where no manifest is guaranteed to be present.
It seems that an MP4Box Patch File would be the appropriate tool to set these boxes in the ISOBMFF.
Can the above be achieved with a MP4Box patch file? And if so, could someone point me in the right direction to at least get some of the boxes accurate. My experience is more in the MPEG-2 TS / HLS domain.
Many thanks in advance.

] | I'm a fan of your GPAC - MP4Box and I'm reaching out to suggest creating a dedicated API for Flutter. Here's why it would be beneficial:
1. **Wider Developer Adoption:** Supporting Flutter would attract more developers to use and integrate your platform.
2. **Simplified Integration:** A Flutter API would streamline the integration process, making it easier for developers to use your platform in their Flutter projects.
3. **Community Engagement:** Embracing Flutter shows your commitment to an active and growing developer community.
4. **Increased Versatility:** Integrating with Flutter would expand your platform's accessibility and usability across multiple platforms.
Your consideration of this request would mean a lot. Looking forward to the possibilities this collaboration could bring.

reason:
in swf_def_bits_jpeg, the type of para destLen to uncompress is uLongf * and can not passed it within a (uLongf *) &osize while type of osize is u32.
swf_def_bits_jpeg:
u32 osize
uncompress((Bytef *) dst, (uLongf *) &osize, buf, AlphaPlaneSize);
Or it will make the destLen much larger than dest buffer len.

seems that para stride to gf_img_png_enc error, makes libpng write out of scope memory.
2173:
gf_img_png_enc(raw, w, h, h*4, GF_PIXEL_RGBA, (char *)buf, &osize);
should it be h*4 or w*4?
Here's some debug info i print: width = 350,heigth = 364,
and i've print the 4*stride value : 1456(4*364) while the step in libpng is 1400(4*350).
May it help.

"gpac",
"gpac"
] | Hello I'm trying to run dasher in dual mode and specify both hls and dash's manifest path explicitly (different manifest destination directory). Similar to the following:
<img width="148" alt="image" src="https://github.com/gpac/gpac/assets/29557802/828f7232-fcd4-4c8e-ad64-54792801b0fd">
Reading the documentation here, this seems possible: https://github.com/gpac/gpac/wiki/dasher#output-redirecting. Specifically the following verbiage:
"This will create a single dasher whose outputs (manifests and segments) will be redirected to the given URLs.
When explicitly loading the filter, the [dual](https://github.com/gpac/gpac/wiki/dasher#dual) option will be disabled unless [mname](https://github.com/gpac/gpac/wiki/dasher#mname) is set to the alternate output name."
Running the gpac command:
```gpac -i someFile.mp4 dasher:dual:mname=/out/dash/dash_live.mpd --segdur=10 --cdur=2 --asto=8 --dmode=dynamic --llhls=br --profile=live --tsb=60 --template='../common/$File$_$Number$' -o /out/hls/hls_live.m3u8 -o /out/dash/dash_live.mpd```
Results in both fout destinations containing a dash manifest (the fout names/paths are correct but the content is dash for both).
Here is the resulting filter graph (paths are simplified above):
```
Filters connected:
fin (src=/Users/ekram/Desktop/ott_assets/Sintel/sintel.mp4) (idx=1)
-(PID sintel.mp4) mp4dmx (dyn_idx=5)
--(PID V1)\
--(PID A2)-> dasher (dual:mname=/Users/ekram/Desktop/test-gpac-multi-out/dash/dash_live.mpd) (idx=2)
---(PID manifest_mpd) fout (dst=/Users/ekram/Desktop/test-gpac-multi-out/hls/hls_live.m3u8:mname=/Users/ekram/Desktop/test-gpac-multi-out/hls/hls_live.m3u8) (idx=3)
---(PID manifest_mpd) fout (dst=/Users/ekram/Desktop/test-gpac-multi-out/dash/dash_live.mpd) (idx=4)
---(PID V1) mp4mx (dyn_idx=8)
----(PID V1) fout (dst=/Users/ekram/Desktop/test-gpac-multi-out/common/sintel_init_track1_.mp4:gfopt:frag:xps_inband=no:psshs=moov:mime=video/mp4) (idx=6)
---(PID A2) mp4mx (dyn_idx=9)
----(PID A2) fout (dst=/Users/ekram/Desktop/test-gpac-multi-out/common/sintel_init_track2_.mp4:gfopt:frag:xps_inband=no:psshs=moov:mime=audio/mp4) (idx=7)
```
Note the `PID manifest_mpd` for both dasher manifest outputs.
I have tried multiple variants of the above gpac command in hopes of getting a working solution. Switching the `fout` / `output`
around (2nd output is m3u8 and mname is m3u8 file path) results in:
<img width="218" alt="image" src="https://github.com/gpac/gpac/assets/29557802/00fa80c0-3e6e-4a48-93df-185aa96d4c9c">
Where the `dash_live.mpd` file has cloned contents of the hls manifest file and the sub-playlist hls files are relative to the first fout destination path (dash location, not the hls location).
(cmd for reference):
```
gpac -graph -i /Users/ekram/Desktop/ott_assets/Sintel/sintel.mp4 dasher:dual:mname=/Users/ekram/Desktop/test-gpac-multi-out/hls/hls_live.m3u8 --segdur=10 --cdur=2 --asto=8 --dmode=dynamic --llhls=br --profile=live --tsb=60 --template='../common/$File$_$Number$' -o /Users/ekram/Desktop/test-gpac-multi-out/dash/dash_live.mpd -o /Users/ekram/Desktop/test-gpac-multi-out/hls/hls_live.m3u8
```
I know running two separate dashers will solve the destination paths detailed above -- but my understanding is that the resulting segment duplication will be a huge performance cost and that is not worth trying to achieve the desired file output structure.
TLDR: Is there a way to specify independent destination paths for hls and dash manifests (and bonus -- dash and top master hls manifest names) when running dasher in `dual` mode? | Is there a way to specify independent destination paths for hls and dash manifests? | https://api.github.com/repos/gpac/gpac/issues/2683/comments | 0 | 2023-11-13T18:48:22Z | 2023-11-28T15:29:17Z | https://github.com/gpac/gpac/issues/2683 | 1,991,252,655 | 2,683 |

Detailed guidelines: http://gpac.io/bug-reporting/
I've identified an issue with Gpac concerning the generation of Low-Latency HLS (LL HLS) playlists when using the x264 encoding profile at level 4.2. Broadcasting a UDP stream containing video and audio, encoded via FFMPEG, fails to produce the correct LL HLS playlists. The stream is broadcast with the following configuration:
```bash
ffmpeg -i "$URI" \
-vf "scale=1280:720,fps=24,drawtext=text='%{localtime} ${FILTER}':x=10:y=10:fontsize=24:fontcolor=white:box=1:boxcolor=black@0.5" \
-map 0:0 -c:v h264_videotoolbox -profile:v high -level:v 4.2 -g 24 -keyint_min 24 -sc_threshold 0 -b:v 3000k -maxrate 4000k -bufsize 6000k -f mpegts "udp://239.0.0.1:$VIDEO_PORT" \
-map 0:1 -c:a aac -ac 2 -b:a 128k -f mpegts "udp://239.0.0.1:$AUDIO_PORT"
```
Attempting to generate an LL HLS playlist with Gpac using the command below only results in a master playlist that contains the audio track, without the video or proper HLS tags:
```bash
gpac \
-i udp://239.0.0.1:5000:gpac:#Representation=normal:#HLSGroup=normal:#HLSMExt=AUDIO=\"normal\" \
-i udp://239.0.0.1:5001:gpac:#Representation=normal-audio:#HLSGroup=normal:#HLSMExt=DEFAULT=YES \
-o test_gpac/playlist.m3u8:segdur=2.0:cdur=0.5:llhls=sf:dmode=dynamic:pssh=mv:template=segment:hlsc \
-threads=-1
```
The generated playlist is as follows:
```
#EXTM3U
#EXT-X-VERSION:6
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:BANDWIDTH=2296,CODECS="mp4a.40.2",DEFAULT=YES
playlist_1.m3u8
```
However, if I change the level to 3.1, it functions correctly and generates the appropriate playlist:
```
#EXTM3U
#EXT-X-VERSION:6
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:BANDWIDTH=1432283,CODECS="avc1.64001F,mp4a.40.2",RESOLUTION=1280x720,FRAME-RATE=24,AUDIO="normal",AUDIO="normal"
playlist_1.m3u8
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="normal",DEFAULT=YES,NAME="normal-audio",URI="playlist_2.m3u8",CHANNELS="2"
```
It's important to note that the HLS tags are also missing when using x264 level 4.2.
This issue suggests a compatibility problem or a bug within Gpac when handling streams encoded at x264 level 4.2, specifically affecting the creation of LL HLS playlists. Any assistance in resolving this would be highly appreciated, as high resolution and frame rates enabled by level 4.2 are essential for our broadcasts.
Note: the command to generate the video :
```
ffmpeg -stream_loop 1000000 -re -i 1080.mp4 \
-filter_complex "fps=30,drawtext=:text='normal %{localtime}:box=1:fontcolor=black:boxcolor=white:fontsize=100':x=40:y=720'" \
-c:v h264_videotoolbox -c:a aac -f mpegts udp://239.0.0.1:8001

"gpac",
"gpac"
] | I am trying to use GPAC to stream a mp4 file via DASH to an Enensys MediaCast gateway. Here is the gpac command line:
```
gpac -graph -log-file=gpac.log -i video/playlist.m3u reframer:rt=on -o 'http://10.21.15.82:8082/uploads/161/manifest.mpd:gpac:segdur=10:cdur=1:asto=9:cmaf=cmfc:profile=live:dmode=dynamic:hmode=push:template=$RepresentationID$-$Number%03d$$init=init$'
```
For an unknown reason, the MediaCast gateway is not seeing the DASH init segments. Unfortunately, there isn't a lot of debugging available on the MediaCast gateway, other than a vague error message of "No DASH init segment received". The minimal documentation on the MEdiaCast gateway says it is looking for init segments with the name format of "$RepresentationID$-init.mp4", which is what gpac appears to be producing.
There are no errors in the gpac log file initially, but after a short while, the following starts appearing in the gpac log file:
```
[HTTP] Failure - body: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

Dear gpac team:
I'm trying out a low latency dash setup with the built-in HTTP server file sink. I tried requesting a ongoing segment with `curl`.
I noticed that even though the header did say `Transfer-Encoding: chunked`, and the transfer is indeed using chunked HTTP chunked transfer correctly, the timing of the chunks delivery is delayed.
I have observed the following when a GET request is made against a segment that is being produced.
1. Transfer the already written data immediately as the first chunk(s).
2. When the segment is fully complete, transfer the rest of chunks.
But according to the docs, it should rather be that a chunk is transferred as soon as received.
My setup to reproduce and demostrate the mentioned behavior:
- `gpac` version
```
gpac - GPAC command line filter engine - version 2.3-DEV-rev612-gcea3eeb7-master
(c) 2000-2023 Telecom Paris distributed under LGPL v2.1+ - http://gpac.io
```
- Command to generate the low latency dash
```
gpac -i video.mp4 reframer:rt=on @ -o http://localhost:8080/live.mpd:rdirs=outdir:segdur=10:cdur=1:reqlog=GET:dynamic:timeout=30
```
- Command to request the producing chunk
```
curl --trace-time --trace-ascii tracefile -o /dev/null http://localhost:8080/video-post_dash_track2_5.m4s
```
- Key traces
- A chunk was sent upfront while the rest of the chunks are all sent at once around 15:34:20
```

Detailed guidelines: http://gpac.io/bug-reporting/
For Compilation on Ubuntu Mantic (23.10) and possibly 22.x versions as well, the `libjack-dev` dependency should be replaced by a `libjack-jackd2-dev` dependency. `libjack-dev` install would remove lots of the existing multimedia packages in the system since `libjack0` is not compatible with the `libjack-jackd2-0` used by Ubuntu.
The version v2.2.1 doesn't compile on 23.10. Master from 2023-10-24 does without problem (Easy install). | For Ubuntu 23.10, libjack-dev needs to be replaced with libjack-jackd2-dev | https://api.github.com/repos/gpac/gpac/issues/2663/comments | 1 | 2023-10-24T12:36:25Z | 2023-10-26T10:38:44Z | https://github.com/gpac/gpac/issues/2663 | 1,959,161,060 | 2,663 |

I checked against the latest release as of 10/17/23 the current master branch at commit 2fb17d2248bc88bd01434096e684d9b61d4d949b .
Description
This AddressSanitizer output is indicating a large OOB read of invalid heap memory past a buffer allocated in the function filein_initialize_ex at [line 248](https://github.com/gpac/gpac/blob/master/src/filters/in_file.c#L248). This exception occurred in the function mpgviddmx_process at [line 1166](https://github.com/gpac/gpac/blob/master/src/filters/reframe_mpgvid.c#L1166) in the file src/filters/reframe_mpgvid.c. This error being an OOB read indicates that the error is related to the source calculation. The size of the read matches the size being iterated in the while(remain) and the read is directly after the allocated memory indicating that the loop is iterating one more time than it should.

"gpac",
"gpac"
] | Hi, sorry if I am missing something available from the documentation.
I looked at gpac's nodejs doc, at the test/gpac.js, at several filter's source code and documentation, at the doxygen as well as the general filter documentation.
I'm trying to write a custom source that feeds data into a filter session using the nodejs API.
I have been testing 2 options:
### 1. using a custom filter
This is my preferred solution, however I keep failing at building a simple graph.
Here's my code:
```
const process = require("process");
const GPAC_NODEJS = process.env["GPAC_NODEJS"] || "share/nodejs/build/Debug/gpac";
const gpac = require(GPAC_NODEJS);
gpac.init();
gpac.set_logs("all@debug");
const fs = new gpac.FilterSession();
const custom_filter = fs.new_filter("mysource");
custom_filter.set_max_pids(-1);
custom_filter.pids = [];
custom_filter.push_cap('StreamType', 'Visual', gpac.GF_CAPS_OUTPUT);
custom_filter.process = function()
{
console.log(`custom_filter.process()`);
return gpac.GF_OK;
}
custom_filter.configure_pid = function(pid, is_remove)
{
console.log(`custom_filter.configure_pid(${pid}, ${is_remove})`);
return gpac.GF_OK;
}
custom_filter.process_event = function(evt)
{
console.log(`custom_filter.process_event(${evt})`);
return true;
}
custom_filter.reconfigure_output = function(pid){
console.log(`custom_filter.reconfigure_output(${pid})`);
return gpac.GF_OK;
}
// const f1 = fs.load("pout");
// const f1 = fs.load("fout:force_null");
// const f1 = fs.load_dst("test.mp4");
const f1 = fs.load("inspect:full");
f1.set_source(custom_filter);
fs.run();
fs.print_graph()
```
The custom filter implementation obviously does nothing useful but logging calls, which never happens as the filter is never connected. What am I missing ?
Do I need to supply a specific argument to the `set_source(...)` function in order to explicitly connect these 2 filters ?
```
f1.set_source(custom_filter, ARG);
```
I tried several options there, but couldn't figure it out.
### 2. using FIO wrapping
FIO wrapping seems like it could also achieve my goal:
```
const fs = new gpac.FilterSession();
const URL = "myuri"
const fio_wrapper = new gpac.FileIO(url, fio_factory);
const f1 = fs.load_src(fio_wrapper.url);
const f2 = fs.load('inspect');
f2.set_source(f1);
fs.run();
fs.print_graph();
```
My understanding is that gpac first reads the file in an attempt to probe it, then resolves a graph based on the result, is that correct ? Is the ressource url actually involved in the graph resolution (eg. graph resolver inferring the source type from a file extension) ?
At this point I have to log each of the FileIO API functions to figure out what happens in different contexts. Is there additional documentation to understand how the FileIO API works internally in different contexts ?
Finally, is there a case for which the FileIO API solution be favoured over the custom filter when trying to create a source ?
Thanks in advance for any help on this. | Implementing a custom source using the nodejs API | https://api.github.com/repos/gpac/gpac/issues/2650/comments | 2 | 2023-10-18T10:07:22Z | 2024-02-16T22:01:32Z | https://github.com/gpac/gpac/issues/2650 | 1,949,365,621 | 2,650 |

SUMMARY: AddressSanitizer: double-free (/home/fuzz/gpac/gpac/bin/gcc/MP4Box+0x4a7292) in free
==2796375==ABORTING
POC file address:
https://github.com/Janette88/test_pocs/blob/main/poc13
Impact
Referencing memory after it has been freed multiple times can cause a program to crash, use unexpected values, memory leak or execute code .This might allow an attacker to write values to arbitrary memory spaces and create an interactive shell with elevated privileges.
