] | If i package a 480p video (480x854), (or any video which has different PAR than its width/height)
GPAC produces the wrong PAR and SAR values in the adaption set.
I use the following command:
```bash
gpac
-i video.mp4:gpac:#PAR=16/9
-o dash.mpd:profile=dashavc264.onDemand:dual:cmaf=cmf2:styp:sfile:bs_switch=both:segdur=15:sbound=closest
```
It produces incorrect output:
```xml
<AdaptationSet segmentAlignment="true" maxWidth="854" maxHeight="480" maxFrameRate="60" par="427:240" lang="eng" startWithSAP="1" subsegmentAlignment="true" subsegmentStartsWithSAP="1">
<Representation id="0" mimeType="video/mp4" codecs="avc1.64001F" width="854" height="480" frameRate="60" sar="1:1" bandwidth="1035863">
<BaseURL>video_track1_init.mp4</BaseURL>
<SegmentBase indexRangeExact="true" indexRange="970-1013">
<Initialization range="0-941"/>
</SegmentBase>
</Representation>
</AdaptationSet>
```
As you can see, GPAC has set the following PAR and SAR values:
```ini
AdaptationSet@par = 427:240
Representation@sar = 1:1
```
These values are wrong, because i specified a PAR of 16:9 at the command line, and the SAR should be calculated from that. Allthough these values will technically work, they will causes conflicts if multiple representations are used.
Lets take a look at what the DASH-IF guidelines [[source]](https://dashif-documents.azurewebsites.net/DASH-IF-IOP/master/DASH-IF-IOP.html#video-constraints) say about that:
> Note: `@width` and `@height` indicate the number of encoded pixels. `@par` indicates the final intended display aspect ratio and `@sar` is effectively the ratio of aspect ratios (ratio of `@width` x `@height` to `@par`).
>
> Given a coded picture of 720x576 pixels with an intended display aspect ratio of 16:9, we would have the following values:
> `@width`=720
> `@height`=576
> `@par`=16:9
> `@sar`=45:64 (720x576 is 5:4, which gives `@sar`=5:4/16:9=45:64)
So, applying this to our example, the correct values (according to DASH-IF) should be:
```ini
AdaptationSet@par = 16:9
Representation@sar = 1281:1280 # is calculated using (width/height)/par , in this case: (854/480)/(16/9)
```
I hope i explained the issue detailed enough :) | [BUG] Aspect ratios are handled incorrectly by GPAC when PAR is different than width/height | https://api.github.com/repos/gpac/gpac/issues/2407/comments | 1 | 2023-02-28T21:10:29Z | 2023-03-08T18:11:01Z | https://github.com/gpac/gpac/issues/2407 | 1,603,818,565 | 2,407 |

I have seen https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide and successfully used kvazaar and gpac to generate tiled videos.
However, I am looking for a method to stitch NxM independently encoded HEVC video stream into one mp4 file.
If I can control using the same video encoding parameters, is it possible to perform the stitching?
It should perform like `vstack` and `hstack` in ffmpeg.

The "Tags" (specifically the section simply called "Tags", as opposed to "Title", "Comments", etc) as applied by Windows Explorer appear to be interfering with the correct functionality of MP4Box. Assigning a single "Tag" will result in no observable impact (MP4Box doesn't even acknowledge it exists), but as soon as a second "Tag" is assigned the file becomes completely incompatible. This persists should the second "Tag" be removed - it's only after all "Tags" have been removed that the file works as expected, at which point you can repeat the process.
The errors presented are as follows (consistent across all tested files):
> [isom] invalid tag size in Xtra !
[iso file] Read Box "Xtra" (start 4803875) failed (Invalid IsoMedia File) - skipping
[iso file] Read Box "udta" (start 4803867) failed (Invalid IsoMedia File) - skipping
[iso file] Read Box "moov" (start 36) failed (Invalid IsoMedia File) - skipping

_There is also another error stating "[iso file] Broken text box detected, skiping parsing.", however this appears on files that otherwise work so I mention it only for the sake of completeness._
I'm unable to provide a demonstration file based on what I've used in my testing. They are both too large and only legal for personal use.
1.0 handled these tags without presenting an issue. It seemed unable to display them, but it at least acknowledged their existence and dealt with them accordingly. They present simply as a "tags" UDTA type, which is not detected in 2.x (files report four UDTA types in 1.0, but only three in 2.x). | MP4Box 2 incompatible with Windows Explorer tags | https://api.github.com/repos/gpac/gpac/issues/2404/comments | 1 | 2023-02-25T13:00:05Z | 2023-03-10T17:56:44Z | https://github.com/gpac/gpac/issues/2404 | 1,599,701,810 | 2,404 |

Using latest nightly on MacOS.
The following command works …
`mp4box frame_0000003.heic -add-image frame_0000003_zbuffer.hvc:ID=50:auxt=urn:mpeg:hevc:2015:auxid:2`
However for my purposes the HEIC requires a Aux Subtype otherwise the depth channel is not seen.
In an Apple reference HEIC this looks like the following (using "_mp4box -diso_" XML dump) …
(from [https://files.michaelzfreeman.org/IMG_0019_A.HEIC](https://files.michaelzfreeman.org/IMG_0019_A.HEIC) )

```
Unless I’m missing a function can a way be added to allow the setting of “aux_subtype=“. Cheers.

- [X] I looked for a similar issue and couldn't find any.

- [X] I give enough information for contributors to reproduce my issue _(Disclaimer: This is foremost a question.)_
I am experiencing some strange things when syncing video files ("Home Videos") from different Macs to an iPod Nano 3rd generation. Before syncing, the videos (on the Mac) have the following media information:
```
Media Type: sbtl:tx3g
QT/3GPP subtitle
Size 320 x 240 - Translation X=0 Y=0 - Layer 0
```
Curiously, after syncing from High Sierra (oldest macOS) and Ventura (newest macOS), the videos (on the iPod) have a modified media information. This causes the iPod not to display subtitles.
```
Media Type: gnrc:tx3g
Subtitle/text 3GPP/Apple Stream
```
On Monterey (released between High Sierra and Ventura), media info is intact ("sbtl"), and subtitles are displayed.
My current workaround for High Sierra and Ventura is to stream copy the videos on the iPod, which reinstates `sbtl`.
Does anyone know what `gnrc` is, why it is applied by *some* macOS, and how to avoid this, in order to get subtitles? The `FOURCC` is elusive on the web and the gpac and FFmpeg sources. FFmpeg generates `sbtl` by default.
PS! Curiously, while "3GPP/Apple Stream" (associated with the obscure `gnrc`) occurs prominently in the MP4Box source, while "QT/3GPP" (associated with the more agreeable `sbtl`) is hardcoded.

Since mp4box can remux mkv to mp4, so I wonder if it is also possible to remux mp4 to mkv.
I tried the following command, `mp4box -add input.mp4 -new output.mkv`
the extension is shown as mkv but actually outputted as mp4. | Question. Does mp4box support remux mp4 to mkv? | https://api.github.com/repos/gpac/gpac/issues/2393/comments | 5 | 2023-02-08T13:21:48Z | 2023-03-14T16:58:02Z | https://github.com/gpac/gpac/issues/2393 | 1,576,115,831 | 2,393 |

Hi. This is on latest macOS (Ventura) with gpac/mp4box installed via home-brew.
I’m needing to create HEIC images from source animation frames and depth buffer produced by Mandelbulber (see attached images) for Apple Object Capture.
For my initial testing I converted the png’s to HEIC using macOS Quick Action —> Convert.
I’m using. …
`mp4box -add-image frame_0000000.heic:primary -add-image frame_0000000_zbuffer.heic:depth:ref=auxl:1 -ab heic -new img.heic`
But get error …
```
No sample found for requested time
Error: Bad Parameter
```
I’m aware that I could make a lossless HEVC video from my source animation frames, one for the colour images and another with the depth buffer frame (just trying to avoid that step to keep things simple).I’m not familiar with HEVC. Would I be able to make lossless video that would retain all the source image data ? Otherwise is it possible to define the use of a still image frame file for mp4box ?

My machine
- `Ubuntu 64bit 18.04.6 LTS`
- `memory` 32GB
- `CPU` AMD Ryzen 7 3700x 8-core processor × 16
- `GPU` NVIDIA GeForce GTX 1660 Ti/PCIe/SSE2
Also tried with building everything on my own (besides ready build apps) with branches
- `gpac` HEAD detached at v2.2.0
- `ffmpeg` release/5.1
- `local rtsp server` gstreamer (1.20)
I have a local rtsp server streaming from a live camera, I want to re-encode the stream to support tiles in order to drop some of them and stream it again
1st step to see if encoding works:
- gpac -i rtsp://127.0.0.1:1234/live.sdp:gpac:enc:c=libkvazaar:input-res=1920x1080:bitrate=2000000:fintra=1:rc::kvazaar-params=tiles=3x3,slices=tiles,input-fps=30 -o http://localhost:8080/live.m3u8:gpac:dmode=dynamic:rdirs=./
and I can use a media player with no problem (there is a 30sec delay)
2nd step to drop tiles:
- gpac -i rtsp://127.0.0.1:1234/live.sdp:gpac:enc:c=libkvazaar:input-res=1920x1080:bitrate=2000000:fintra=1:rc::kvazaar-params=tiles=3x3,slices=tiles,input-fps=30 tilesplit:tiledrop=1 tileagg -o http://localhost:8080/live.m3u8:gpac:dmode=dynamic:rdirs=./
Get a lot of errors
````
[RTP] Rejecting too early packet (TS -1666837258 vs signaled rtp time 1 - diff 43389 ms)
````
3rd step to drop tiles with the addition of live profile:
- gpac -i rtsp://127.0.0.1:1234/live.sdp:gpac:enc:c=libkvazaar:input-res=1920x1080:bitrate=2000000:fintra=1:rc::kvazaar-params=tiles=3x3,slices=tiles,input-fps=30 tilesplit:tiledrop=1 tileagg -o http://localhost:8080/live.m3u8:gpac:profile=live:dmode=dynamic:rdirs=./
No files are created locally (`live.m3u8` and `media segments`) and nothing is streaming. Just the message on the terminal

] | Hello, i want to use the very nice feature of generating dynamic playlists with gpac.
i am using the latest version of gpac under `Ubuntu 20.04.4 LTS x86_64`
`gpac - GPAC command line filter engine - version 2.3-DEV-rev23-g5a733aec-master`
i tried the command:
`gpac -i pl.m3u:floop=-1 -o /var/www/html/stream/hls/live.m3u8:dmode=dynamic:sreg -logs=media@debug`
an nginx rtmp server is serving the stream and everything works fine. it is the same for `hls` and `dash` .
basic playlist content:
```
out-01.mp4
out-02.mp4
out-03.mp4
out-05.mp4
```
i am expecting that the stream is looping over all files until the playlist gets updated. but as you can see after the first play-through it just loops over the first 2 entries.
```shell

If you play the received file using Plex or from a NAS via DLNA, then sound problems begin from 5-6 minutes (the sound starts to stutter). With other videos from other streaming services, I did not notice such a problem. | Multiplexing Dolby Vision Profile 5 | https://api.github.com/repos/gpac/gpac/issues/2373/comments | 3 | 2023-01-14T22:33:42Z | 2023-03-13T09:49:33Z | https://github.com/gpac/gpac/issues/2373 | 1,533,533,551 | 2,373 |

"gpac",

] | Hi,
I'm using docker to scale my service and I need `gpac` as a dependency just like `FFmpeg`, but I couldn't install the latest [gpac](https://gpac.wp.imt.fr/downloads/) on my docker container.
I'm using `amd64/debian:11` from [here](https://hub.docker.com/r/amd64/debian/) and installing the dependencies mentioned in your [GPAC Build Guide for Linux](https://github.com/gpac/gpac/wiki/GPAC-Build-Guide-for-Linux) guide here, to make sure that I have all the required dependencies.
```dockerfile
FROM amd64/debian:11
WORKDIR /app
# Install dependencies
RUN apt-get update
RUN apt-get install gdebi zlib1g-dev libfreetype6-dev libjpeg62-turbo-dev libpng-dev libmad0-dev libfaad-dev libogg-dev libvorbis-dev libtheora-dev liba52-0.7.4-dev libavcodec-dev libavformat-dev libavutil-dev libswscale-dev libavdevice-dev libxv-dev x11proto-video-dev libgl1-mesa-dev x11proto-gl-dev libxvidcore-dev libssl-dev libjack-dev libasound2-dev libpulse-dev libsdl2-dev mesa-utils -y
COPY ./gpac_2.0.0.deb ./gpac.deb
RUN apt-get update && \
apt-get install ./gpac.deb
CMD ["pwd"]
```
When building the image, All the dependencies are installed successfully, but it fails to install `gpac` due to _missing dependencies_.
```
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
gpac : Depends: libavcodec57 (>= 7:3.4.8) but it is not installable or
libavcodec-extra57 (>= 7:3.4.8) but it is not installable
Depends: libavdevice57 (>= 7:3.4.8) but it is not installable
Depends: libavfilter6 (>= 7:3.4.8) but it is not installable or
libavfilter-extra6 (>= 7:3.4.8) but it is not installable

Depends: libavutil55 (>= 7:3.4.8) but it is not installable
Depends: libswscale4 (>= 7:3.4.8) but it is not installable
```
I created a new Linode `Debian 11` VM to test this issue and tried to install [gpac](https://gpac.wp.imt.fr/downloads/) directly without any dockerization, it worked without any issue!
I really want this fixed, Any help will be appreciated.
_Note_
```bash
apt-get install gpac -y
```
Using `apt` to install gpac is what I used to have, but I need the latest release of gpac to fix some issues and avoid deprecated APIs.

the segment index box signals SAP_type=1 and the mpd signal subsegmentStartsWithSAP="1"
This should for this specific file be 2, as the first decoded sample is not the first one displayed.
also it may be easier to always signal 2 for dash as sap type 1 is a subset of sap type 1.
My suggestion is to put the correct SapType in the mpd and segment index or always put 2

I'm trying to generate a stream from ll-dash but when I do it gpac throws this : `[Dasher] First CTS 17160 in segment 9 drifting by 1.16 (more than half a segment duration) from segment time, consider reencoding or using segment timeline` or `[Dasher] Segment 34 duration 0.88 less than half DASH duration, consider reencoding or using segment timeline` which generates latency and the video is out of sync with the audio.
I tried to put the `stl` option but the video does not look smooth and has enough latency.
I thought it was due to CPU resources but everything is fine, I also tried to increase the gpac threads but I don't see any change in performance.

] | Hi all,
As you continue working towards publishing version 2.2 to the GPAC website, please take a moment to review your code for the Legacy builds page; the Markdown tag `textimport` was not interpreted by your platform. Check out the screenshot:
https://gpac.wp.imt.fr/downloads/gpac-legacy-builds/
Just as a side note, the Downloads page is still showing v2.0, even though the 2.2 announcement is already published on the website. I am not sure if you are still building the v2.2 downloads page somehow.

"gpac",
"gpac"
] | I would like to support GPAC by implementing ephemeral preview environments, powered by [Uffizzi](https://github.com/UffizziCloud/uffizzi)
Uffizzi is an Open Source, full stack, previews engine, and our platform is available completely free for GPAC (and all open source projects). An Uffizzi integration with GPAC will provision preview environments for every PR opened on GPAC in the cloud, allowing faster reviews, faster merges, and increased release velocity.
[Here are the open-source projects](https://uffizzi.notion.site/) which are currently using Uffizzi to provision previews.
Uffizzi is purpose-built for the task of previewing PRs and it integrates with your workflow to deploy preview environments in the background without any manual steps for maintainers or contributors.
I'll go ahead and create an Initial PoC for you if you think there is value in this proposal.
I work on the Uffizzi project.

the stss box absent (cmaf mention this shall be present if not all samples are sync samples which is not the case for this video track)
tkhd flags shall be 0x000007 (23000-19 9.2) for video tracks , it is set to 3 in my test file.
It would be great if these can be fixed to improve the CMAF compliance, thank you

"gpac",
"gpac"
] | I have had some issues with adding in chapters, I will lump them here, I notice no github issues in past cover people's experiences, I presume you could be ignorant.
1. Yes you have to escape some characters (#;), but I attempted adding some and they were omitted even with escaping. Here is a sampling of my disappointments: …’“”/¹²³¼½¾§ (quotes are the slanted types) some seem to be rather elementary (not needing Unicode). The player should be able to show it.
2. I notice limit is 128 long. If this cannot be expanded, perhaps you can look at the bug on the 128th character, though I was using MPC-HC 2013, when you add the last character extra symbols are displayed, I think they differ between files, but are same between chapters. Added characters can be Asian. Maybe a bug in player?
3. The 128 character limit may be reduced to a smaller limit with many(60+) chapters but I couldn't be bothered exploring this, that was for a 339mb audio that is super long. I can submit what I did if you must have it, extract and extend whats there already.
4. I thought I had troubles updating when I tried to use one I applied chapters already, so give that a go if you attempt the above.
5. To save on lines can you allow a global timebase entry. I omit since not convenient as is.
Here is some stuff to get you going. Command:
"C:\Program Files\GPAC\ffmpeg" -i infile -i D:\ADD.txt -map_metadata 1 -codec copy outfile
My generator is a spreadsheet (I paste delimited data from elsewhere), I use Npp to convert tabs to carriage returns. Title length is capped here at a low figure because limit seemed to be less. Material to paste at A3:
`[CHAPTER] ="START="&M3 ="END="&M4-1 =LEFT("TITLE="&G3,98) x x Title x x x x x =N3*1000000000 =Q3+P3*60+O3*60*60 0 0 0` GitHub not showing tabs x is blank cell. copy first four columns to Npp.

[
"gpac",
"gpac"
] | This may be deemed insignificant to bother with - unless you are fastidious.
Ffmpeg -r causes media length to extend and is prominent if value is very low. The audio runs out before video concludes.
Original length is 4m53. At 0.1 FPS the length is 5m20; at 0.2 FPS the length is 5m10.
Original length is 4m15. At 0.1 FPS the length is 4m50; at 0.2 FPS the length is 4m30.
The images in the 0.1 and 0.2 files update at the correct periodicy, but will become faster if I fix the length.
I also notice Ffdshow OSD reports half the frames by end of file that ffmpeg says is present after encoding (27 to 54 for 0.2; 29 to 14 for 0.1 on the second file).
Please be aware media players can become buggy at low FPS.
This is using FFMPEG in recent release.

I just obtained 32 bit from
https://gpac.wp.imt.fr/downloads/
To see if a bug has since been fixed. Mp4box seems to not be 32 bit. Ffmpeg runs. Installer ran. Cannot locate previous version of installer to see if my bug is there.
As for the bug, frame rate specification is being ignored with one video specifically, it wants 29.08, I want 29.04 and 5fps test fails.
Using: -add AVfile -fps 5 AVoutfile
Also tried: …\mp4box" -add E:\copy.mp4#audio -add E:\copy.mp4#video:fps=5.0 C:\Recov\out.mp4
The first was tried on a short clip with success so shouldn't be command issue…

MP4Box - GPAC version 1.0.1-rev1.0.1+dfsg1-4+deb11u1
When "no space left on device" error occurs MP4Box produces so many lines of errors that I cannot event log it into my db.
Is there any option to limit error message to 1 line? Is it fixed already in the latest version of gpac?

- [NA] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...).

It would be useful for the Readme to include information on the various dependencies needed to build GPAC from source code. On Windows, I found that I had to obtain SDL and put it in `extra_lib\include\SDL` and `zlib.lib` into `extra_lib\lib\x64\Debug` and there is more to do with `libcryptoMDd.lib`.
Even better than guidance information would be a PowerShell of Command script that would `curl` and `unzip` the required items into the relevant locations.

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
Hi, seeing some weird behavior when playing my hevc encoded tiled video following the guide here https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide.
when running the following command
gpac -gui http://{ip}/path/to/mpd
i get the following and my video plays as normal
However, when running the following command " gpac -play http://{ip}/path/to/mpd" or using the DASH Client python example i get the following.
only the bottom 6th of the player is shown. Any ideas as to why this is happening or what im missing here. I would really like to use the DASH client python example as i would like to implement my own adaptation algorithm.
Appreciate any help thanks!

### Impact
This is capable of causing crashes and allowing modification of stack memory which could lead to remote code execution. | stack-buffer-overflow in gf_rtp_builder_format_sdp | https://api.github.com/repos/gpac/gpac/issues/2320/comments | 0 | 2022-11-22T04:28:19Z | 2022-11-30T11:07:56Z | https://github.com/gpac/gpac/issues/2320 | 1,459,040,705 | 2,320 |

Hi,
After following the guide here https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide i was able to produce a tiled hvc and was able to dash the video producing multiple m4s files etc. Using the following GPAC version: 2.1-DEV-rev492-gbd1a8e990-master
I then started a local http server in that folder and ran the following command:
gpac -gui http://{ip}:{port}/dash_tiled.mpd
however i immediately get this error and the video does not play
[DASH] Error in downloading new segment http://{ip}:{port}/video_tiled_360p_dash_track1_1.m4s: Connection to server closed
I then closed the http server and ran the following command:
gpac -gui dash_tiled.mpd
and the video played no problem. Would appreciate any help trying to debug this issue.

2、
when stack size of programe stack is too small , it triggered stack overflow and caused segmentation fault (core dumped).
Hope it's helpful for fix it.

"gpac",
"gpac"
] | Hello,
I've been pounding my head with this issue and cannot find an appropriate resolution.
I have a file (called filename.alac) which contains the raw ALAC stream, specifically the mdat payload. (Equivalent to the output from ` mp4box -raw filename.m4a` where filename.m4a contains an alac stream)
I am trying to mux this raw stream into an m4a (M4A /mp42/isom) container. Is this possible with MP4Box?
I have tried the following command:
`mp4box -add filename.alac#audio filename_new.m4a`
But I received the following output:
```
[Importer] Cannot load filter for input file "filename.alac"
Failure while importing import: Requested URL is not valid or cannot be found
Error importing filename.alac#audio: Requested URL is not valid or cannot be found
```

"gpac",
"gpac"
] | Hi all,
Does anyone have any examples of reading and maybe queueing samples from MP4Box and creating an AudioBuffer from these?
Currently I have something that creates EncodedAudioChunks and it works great, but I'm having trouble using Web Codecs on the audio side to work well with AudioBuffers from elsewhere, so I'm thinking that I'd like to avoid using Web Codecs on the audio side. Unfortunately I fell short trying to process these samples without making the EncodedAudioChunks (other than decoding them all with Web Codecs)
Thanks!

Should target duration be `4` if segments were `3.84s` ?

**Side question:** Also would like to set `DEFAULT=YES | DEFAULT=NO` attribute per audio EXT-X-MEDIA lines, possible?

ps: The issue could be verified using the poc in issue 2294 and 2296. The patch of issue 2294 and 2296 was not perfect because it still existed memory leak risk .
