Hello:
I have one video file: 1.mp4, it contains only one video track and only one audio track. I want to extract the only audio from it, but I don't know the audio track ID, sometimes, it is 2, but most of the times (90%+), the audio track ID will be a high number, like 256, 257 or 1001, there is no way to know the track ID without using mp4box -info.
However, I know that the MP4 file has only one audio track.
Can I run mp4box to extract the audio track without knowing its audio track ID?
ffmpeg can do this, but I prefer to use mp4box.

Hello:
I have one video (MP4 format) file: 0.mp4.
I want to split it by 3 time ranges: from 00:00:10 to 00:00:20; from 00:00:45 to 00:01:00; from 00:02:00 to 00:03:00. And then merge/concat them into one video file: merge.mp4.
I know I can use splitx to split 0.mp4 into 3 files, like: 1.mp4, 2.mp4, 3.mp4, then run -force-cat command to merge/concat them into one file: merge.mp4
But I want to know if I can use one command to skip the middle steps and generate the result directly.
FFMPEG has similar command like: between(t, t0, t1) + between(t, t2, t3) ...
But I want to know if I can do the same with MP4box.
Thanks,

Let's say I have 3 video (mp4 format) files: 1.mp4, 2.mp4, 3.mp4
I can use the following command to concat them:
mp4box -force-cat -cat 1.mp4 -cat 2.mp4 -cat 3.mp4 merge.mp4
This works well. However, when I want to extract audio from the merge.mp4 file, I have to manually use mp4box -info merge.mp4 to find what is the track ID# for audio, some times, this value is rather high, like 256 or 257.
I want to know if it is possible to set video/audio track ID when I concat multiple videos, all the videos have the same resolution and frame rate.
But I want to forecily set the audio track ID# to 2, and set video track ID# to 1.
Is it possible, if yes, please provide some command samples.

Hello:
I have one audio file (aac format) named: 1.aac, and one video file (mp4 format) named: 1.mp4, the video file has no audio, and its duration is 5 seconds longer than the audio file.
Let’s say that: 1.aac file has duration of 55 seconds, and 1.mp4 file has duration of 1 minute.
I want to make one video file: merge.mp4 with audio from 1.aac, and video from 1.mp4.
But with one requirement that the audio start from the 5th second, therefore, the audio and video will end at the same time at the end of merge.mp4.
I can’t find any example on how to do this using MP4Box, however, FFMPEG has such parameter, but I prefer to use MP4Box, as it is faster and better.
I am using MP4Box version 2.0 on Windows 10.
Please advise,
Thanks,

] | Hello!
I've noticed that MP4Box is changing the values of my HDR10 mastering display characteristics (i.e. the SMTPTE ST.2086 metadata that x265 injects into the HEVC bitstream).
When I use mediainfo to inspect the original MP4 out of ffmpeg I see what I specified:
```
Mastering display color primaries : BT.2020
MasteringDisplay_ColorPrimaries_Source : Stream
Mastering display luminance : min: 0.0050 cd/m2, max: 1000 cd/m2
MasteringDisplay_Luminance_Source : Stream
```
However, when I look at the remuxed MP4 that comes out of MP4Box now things are really weird:
```
Mastering display luminance : min: 0.0768 cd/m2, max: 1000 cd/m2
MasteringDisplay_Luminance_Source : Container
MasteringDisplay_Luminance_Original : min: 0.0050 cd/m2, max: 1000 cd/m2
MasteringDisplay_Luminance_Original_Sour : Stream
Maximum Frame-Average Light Level : 768 cd/m2
MaxFALL_Source : Container
```
Also, MP4Box seemingly made up a MaxFALL value as well!
Where did these values come from? I've used Vega stream analyzer and I see the SEI messages on the IDRs for both the content light level (0 for maxcll and maxfall) and mastering display (0.005 - 1000 nit BT. 2020 D65) signaled with no inconsistency.

HEVC Import results: 120 samples (253 NALUs) - Slices: 2 I 30 P 88 B - 6 SEI - 2 IDR - 0 CRA
HEVC Stream uses forward prediction - stream CTS offset: 3 frames
HEVC Max NALU size is 15170 - stream could be optimized by setting nal_length=2
0.500 secs Interleaving
```
I did notice that just remuxing directly instead of demuxing and then muxing that works around this for some reason. For example:
```
MP4Box -add fake_hdr10.mp4 new.mp4
```

Impact
This is capable of causing crashes and allowing modification of stack memory which could lead to remote code execution.

"gpac",
"gpac"
] | # Description
When GPAC tries to parse a MP4 file, it calls the function `diST_box_read()` to read from video. In this funtion, it allocates a buffer `str` with fixed length. However, content read from `bs` is controllable by user, so is the length, which causes a buffer overflow.
```
char str[1024];
i=0;
str[0]=0;
while (1) {
str[i] = gf_bs_read_u8(bs);
if (!str[i]) break;
i++;
}
```
# Impact
Since video content is absolutely controllable by users, an unlimited length will cause stack overflow, corrupting canary or even get shell.
# Mitigation
We can just set a length limit to it, making it less than 1024 byte. See pull request https://github.com/gpac/gpac/pull/2174 .
# Reproduce
On Ubuntu 2004, make with this.
```
./configure --static-bin
make
```
Run the following command with POC.mp4.
```
$ MP4Box -info ./POC.mp4
```
You may get a stack smashing detectde error, which indicates that CANARY is crashed.
```

"gpac",
"gpac"
] | I'm using MP4Box to tag some AAC audio files (using the **-itags option**) and I'm having difficulty getting the Genre metadata to display in the players that I've tested the files in.
The other metadata fields are showing up across all players, but Genre does not show in iTunes, Windows Media Player, VLC, or Audacity. Editing the internal "tag" of the genre from "©gnr" to "©gen" allows the Genre to show in Windows Media Player, VLC, and Audacity, but it still does not display in iTunes. This change is a binary edit, and I haven't found a way to do this in MP4Box.
Is there another way that we need to add Genre metadata so it shows consistently across all players?

] | Hello,
I'm trying to play a video in VR mode using HEVC and DASH SRD as follows:
`gpac -i DoiSuthep_dash_22_50.mpd#VR @ compositor @ vout`
But after a few seconds the video seems to have colour conversion issues as shown below:
The manifest was made following [this](https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide) tutorial. It has two qualities and it seems that the problem happens when it has a quality change, but I am not quite sure.
I have found a similar issue #1919, but his solution did not work for me.
Any help will be very appreciate it.

SUMMARY: AddressSanitizer: heap-buffer-overflow isomedia/isom_write.c:8515 gf_isom_add_sample_aux_info_internal
```
When `sampleNumber=76` and `saiz->sample_alloc=32`, `saiz->sample_alloc` will double to 64 at line 8505. Therefore, `saiz->sample_info_size` points to a heap chunk of **64** bytes ( line 8506 ).
On lines 8514-8515, the loop is controlled by `sampleNumber`, which accesses the data in `saiz->sample_info_size` up to the **75th** byte, causing a heap buffer overflow vulnerability.
This is mainly due to the **missing checks** for `sampleNumber` and `saiz->sample_alloc` .

Description
A inf loop security issue in gpac/gpac
Proof of Concept
The issue occurs in code: src/media_tools/avilib.c#L1974, when the gpac avidmx filter parses the AVI format file.
choose a simple AVI format file, the data's header is as follows in xxd mode
$ xxd ./1.avi | head -n 2
00000000: 5249 4646 e81b 0100 4156 4920 4c49 5354 RIFF....AVI LIST
00000010: c222 0000 6864 726c 6176 6968 3800 0000 ."..hdrlavih8...
Use vim in xxd mode, to change the header's size member hex data to 0xfffffff8(-8), the modified data is as follows
$ xxd ./1.avi| head -n 2
00000000: 5249 4646 e81b 0100 4156 4920 4c49 5354 RIFF....AVI LIST
00000010: c222 0000 6864 726c 6176 6968 f8ff ffff ."..hdrlavih....
Then run command with avidmx filter, you will observe an inf loop situation.
./gpac -i ./1.avi -o 123 avidmx
Its stack backtrack is as follow

"gpac",

] | **Description**
I'm using GPAC to recreate DASH mpd's and HLS playlists. That's to simulate an event from a static asset, or creating a new playlist from 2 individual static assets.
```
gpac --forward=segb -i asset/manifest.mpd -i asset2/manifest.mpd -o merged.mpd:sigfrag:dual
```
```
gpac --forward=segb -i asset/manifest.mpd reframer:rt=on @ -o live.mpd:sigfrag:dynamic:tsb=-1:dual
```
**Expected**
The HLS playlist also contains the directory in the list of individual fragments.
**Actual**
In both cases the resulting HLS playlist for the chunks doesn't contain the `asset` or `asset2` prefix for the individual fragments. It does contain it for the init fragment however.
**Environment**
- macOS Monterey 12.3
- GPAC version 2.0-rev0-g418db414-master | Missing directory in HLS playlist generated from existing MPD | https://api.github.com/repos/gpac/gpac/issues/2152/comments | 2 | 2022-03-24T09:41:09Z | 2022-04-06T07:34:52Z | https://github.com/gpac/gpac/issues/2152 | 1,179,253,803 | 2,152 |

"gpac",
"gpac"
] | I'm trying to use MP4Box to tag some AAC audio files (using the **-itags option**) and I'm getting an unexpected error when trying to add these two tags:
- record_company (A9mak)
- publisher (A9pub)
MP4Box reports an error for them as:
`[iso file] Unknown box type A9mak` respectively
`[iso file] Unknown box type A9pub`
Dumping the tags with MP4Box -disox shows that the tags are added in the file, but with a **Container=unknown** and the value as **data:application/octet-string** (vs expected text).
Here's how the metadata read back **is shown**:
`<UnknownBox Size="35" Type="A9mak" Specification="unknown" Container="unknown" value="data:application/octet-string,41396D616B2D544553540D" >`
`<data Size="27" Type="data" Version="0" Flags="1" Specification="apple" Container="ilst *" >`
`</data></UnknownBox>`
And here's what I **expected**:
`<record_company Size="10" Type="A9mak" Specification="apple" Container="ilst data" value="A9mak-TEST" >`
`<data Size="26" Type="data" Version="0" Flags="1" Specification="apple" Container="ilst *" >`
`</data></record_company>`
The tags are set per MP4Box documentation: https://github.com/gpac/gpac/wiki/mp4box-other-opts#tagging-support
Here's **how to repro** (files available at: https://www.dropbox.com/sh/tnmhfy5cx2apxju/AABVZV1ssiGWwA9_42p8H-Pta):
`copy /y Test-ORIG.m4a Test.m4a`
`mp4box.exe -itags mp4_metadata-full-set.txt Test.m4a`
`mp4box.exe -disox Test.m4a -std > Test.m4a.xml`
The error is **not file dependent** (I've seen it reproduced on all files I tried) and it's **reproducible on latest GPAC** (MP4Box - GPAC version 2.1-DEV-rev74-gfa127347-master).
I am not able to find any other reports of such errors.
I have done a test with all the tagging elements that are supported by MP4Box and discovered there are a few more that exhibit the same issue. Here's the full list of tags that fail:
- Unknown box type A9ard
- Unknown box type A9arg
- Unknown box type A9aut
- Unknown box type A9cak
- Unknown box type A9des
- Unknown box type A9dir
- Unknown box type A9equ
- Unknown box type A9lnt
- Unknown box type A9mak
- Unknown box type A9ope

"gpac"
] | MP4Box.exe has an `pssh=m` option to write PSSH atom only in a manifest `<cenc:pssh>xxx</cenc:pssh>` element. Is it possible to omit PSSH from both init.mp4 and manifest, maybe `pssh=none` option?
Additionally is it possible to remove `PSSH` atom from the existing init.mp4 file? At the moment I am using a java application using mp4parser.jar library to drop pssh atom.

## description
Hello, I was fuzzing a old version gpac (v0.7.1) and found some bugs that seems not been fixed yet.
Although the pocs cannot produce the error in the latest version, I didn't found any issue corresponding to these bugs and the buggy code location looks similar in the latest version. **I check corresponding code location and search issues manually and didn't find anything.**
So I think maybe these pocs are just blocked by the format check and could be triggered if the file format are fixed. Unfortunately now I'm working on a fuzzing paper and cannot provide a poc for the latest version.
If you have time, Could you help check if these bugs still exists in the latest version? Thanks.
## steps to compile
```
git checkout v0.7.1
./configure --cc=clang --cxx=clang++ --enable-sanitizer
make -j$(nproc)
./bin/gcc/MP4Box -diso POC
```

When using MP4box to segment MP4 files using inband parameter sets for bitstream switching the generated manifest references non-existent initialization segments. Only one initialization-segment is produced, which is fine, but the MPD-file references it like this: `initialization="ib_$RepresentationID$_.mp4"`. The template string contains the `$RepresentationID`, which probably shouldn't be the case, when only a single init segment is generated.
Invocation:
```
./bin/gcc/MP4Box -dash 4000 -rap -bs-switching inband -segment-name 'ib_$RepresentationID$_$Number%03d$' -out ./inband.mpd foreman_qp30.266 foreman_qp40.266
```
Output files:
```
ib_1_001.m4s
ib_1_002.m4s
ib_1_.mp4
ib_2_001.m4s
ib_2_002.m4s

Hi,
For the provided test input, `MP4Box -bt issue-2137 -std` would produce inconsistent results. To reproduce:
- gpac: git head at the time of report (commit 595e437b3de00bce23d09306d23fbc891334e241)
- Compile gpac with `-O0` and `-O3` with either gcc or clang.
- Run `MP4Box-O0 -bt issue-2137 -std > out-O0.txt` and `MP4Box-O3 -bt issue-2137 -std > out-O3.txt`.

normal.mp4 and mp4frag.mp4 can be played well in mac quicktime player Version 10.5 (1086.4.2)
output.mpd and normal_dashinit.mp4 can be played well in all browser player
However mp4box output normal_dashinit.mp4 could a trigger a a/v sync issue while seeking in quicktime player
try to seek to the middle position of the mp4, you will found the count down a/v is not sync.
and normal_dashinit.mp4 has no audio for some time in latest version VLC player(Version 3.0.16 Vetinari (Intel 64bit) )
mp4frag.mp4 and normal_dashinit.mp4 are all fragment mp4 , although the format is a little different.
I guess there must be some timestamps wrong in the mp4 header , it caused this av sync issue
may be related to this issue, I am not sure.

] | Hello,
I am building ffmpeg and mp4box with the [ffmpeg-windows-build-helpers](https://github.com/rdp/ffmpeg-windows-build-helpers)
Since recently mp4box building is compromised.
I think it has something to do with a typo in the file `utils/os_file.c`.
There it says in lines 411, 422 and 877: `st.st_mtim.tv_nsec`.
I think it should say `st.st_mtime.tv_nsec`.
Could you please check and fix that? Thanks. :)

Hi,
I built `gpac` twice with `gcc-11 -O0` and `gcc-11 -O3` separately. For the provided input, `MP4Box -dxml` would produce different outputs. Reproduce as follows:
- Compile `gpac` twice with `gcc-11 -O0` and `gcc-11 -O3` to obtain two versions MP4Box: `MP4Box-O0` and `MP4Box-O3`
- Run `MP4Box-O0 -dxml $issue-2132 -std > out-O0.txt 2>&1` and `MP4Box-O3 -dxml $issue-2132 -std > out-O3.txt 2>&1`
- Compare with `diff -y out-O0.txt out-O3.txt` and you'll see these two files differ (`out-O3.txt` shown on the right has two more lines than `out-O1.txt`)

I reported a similar bug before (https://github.com/gpac/gpac/issues/2130), which was due to an uninitialized variable. I guess this s might have a similar root cause. I tried to build gpac with clang's MemorySanitizer but failed. `Valgrind` would produce more than a hundred errors on this input. I'm not sure if that's useful or not. | Incorrect result produced by `MP4Box -dxml` | https://api.github.com/repos/gpac/gpac/issues/2132/comments | 0 | 2022-03-05T14:10:05Z | 2022-03-07T14:07:09Z | https://github.com/gpac/gpac/issues/2132 | 1,160,361,817 | 2,132 |

Hi,
For the provided test input, `MP4Box -bt issue-2131 -std` would produce different results per run. To reproduce
- Compiler: gcc-11 (doesn't really matter, I tried with clang-13 as well)
- Platform: Ubuntu20.04.3 LTS, x86_64
- gpac version: git HEAD f6b88a11929c7163f2caf91d245ae4ca83ccc10a
- Run `MP4Box -bt issue-2131 -std` multiple times and you'll observe they produce different results. Below are `diff` results of two runs.

I tried to use AddressSanitizer, UndefinedSanitizer, and MemorySanitizer, all of them didn't complain. Based on the results, I suspect it's probably due to floating-point imprecision.

I use `gpac` reading `RTMP` input and serve them with ll-hls, the command is like:
```
gpac -i 'rtmp://:1935/live/abc:gpac:rtmp_listen=1' reframer:rt=on -o http://127.0.0.1:8080/ll-hls/live.m3u8:gpac:segdur=4:cdur=1:profile=live:dmode=dynamic:hmode=push:llhls=sf
```
Now I want to add some arguments which can transcode rtmp to different resolution streams and use ll-hls provide these streams so web player can choose one of them by estimated bandwidth, which is so called adaptive stream media. I have read documents and found nothing. I want to know whether `gpac` support this operation and how to change above command.

"gpac",
"gpac"
] | Hello, this is less of an issue and more of a request for some information/assistance. I'd like to see if I can get the OpenXR loader working inside of GPAC's video player to allow a majority of the current VR runtimes (SteamVR, Monado, etc.) to work with GPAC so that non-mobile headsets can be used to watch 360 videos as well. There is also some coming support for standalone headsets such as the Quest 2, so it could also be a possible solution for this issue #1937.
What I've done so far -
Explored OpenXR Loader Structure
Explored GPAC source looking for render/frame update sections
Realized that I need to get the viewport frame(s) / frame buffer(s) instead of the full frame buffer(s)
My questions -
1. Where are the buffers and frame update functions for the viewport in VR mode? (I've been looking in camera.c, visual_manager.c, visual_manager_3d.c, but haven't found anything specifically viewport, might just be missing them)
2. Is there an implementation somewhere for Z-axis rotation of the camera in VR mode? (I knew there is one for X and Y because the current 360 player exists, but tilting the viewport was something I wasn't able to find in camera.c or navigate.c)
3. I remember there was a section on viewport resizing, but is there anything dedicated to FOV based viewport size or is it resolution based only?
An answer to these three questions would be a great help thank you for your time!

Hi, thanks for the new release! However, I can't seem to be able to build MP4Box on neither Ubuntu, nor Arch Linux.
On Ubuntu I get:
```
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/11/../../../x86_64-linux-gnu/libfreetype.a(sfnt.o): in function `woff2_open_font':
(.text+0xb76d): undefined reference to `BrotliDecoderDecompress'
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:56: gpac] Error 1
```
Following either the [new](https://github.com/gpac/gpac/wiki/GPAC-Build-Guide-for-Linux) instructions or the [old](https://github.com/gpac/gpac/wiki/GPAC-build-MP4Box-only-all-platforms).
On Arch Linux I get:
```
/usr/bin/ld: cannot find -lnghttp2: No such file or directory
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:56: gpac] Error 1
```
I do have `libnghttp2` and `nghttp2` installed, not sure why I get this error...

"gpac",
"gpac"
] | Hi,
Thanks in advance for any help. Please let me know if I should send more information privately.
**Summary**
I had a `sample.mp4` file which has embedded EMSG boxes carrying custom metadata. To serve it via DASH, I used MP4Box to generate the mpd manifest file, and MP4Box generates two files for me
- `sample_dash.mpd`
- `sample_dashinit.mp4`
**Expected Result**
The EMSG boxes in the original fMP4 is preserved in `sample_dashinit.mp4` and served via `sample_dash.mpd`
**Actual Result**
The generated sample_dashinit.mp4 no longer have EMSG boxes.
**Repro Steps**
1. Take any fragmented MP4 file with EMSG boxes
2. run `MP4Box -dash 100000 sample.mp4`
3. Load the generated `sample_dashinit.mp4` using https://gpac.github.io/mp4box.js/test/filereader.html, and no EMSG boxes are in BoxView > TreeView
I might have missed any usage to preserve the EMSG boxes - can someone help advice any proper usage of MP4Box or any workaround in this case? Thanks.
Also copying the generated mpd file

- [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 use gpac to cut a mp4 file into ll-hls files and use nginx to serve them. gpac command I used is:
```shell
gpac -i ~/Videos/436256398-1-208.mp4 -o res/playlist.m3u8:gpac:segdur=6:cdur=1:profile=live:dmode=dynamic:rdirs=outdir:llhls=sf
```
I use https://www.theoplayer.com/ll-hls-test-page to verify ll-hls and find that the video is playing for 2~3s then it starts buffering infinitly. I use sample ll-hls test url and it can play normally and I believe that bandwidth is not bottleneck because I run nginx on `localhost`.
I try to build `gpac` by myself, also try to use latest nightly prebuilded version of `gpac` on [gpac official site](gpac.io) on Ubuntu 18.04, but this question still happpen. I want to know why and how to fix this question. | gpac generated ll-hls files cannot play normally | https://api.github.com/repos/gpac/gpac/issues/2119/comments | 6 | 2022-02-16T11:22:23Z | 2022-02-18T17:33:27Z | https://github.com/gpac/gpac/issues/2119 | 1,139,883,797 | 2,119 |

"gpac",
"gpac"
] | Command run:
`gpac --lowlat=no --buffer=8000 -i out/live.mpd#VR @ compositor:fsize=true:sz=true:tvtd=partial @ vout @1 aout`
The test data used is [here](https://www.mediafire.com/file/2r7s1i0tst06ane/out.zip/file)
What happens:
The vout opens a small window, with a content resolution corresponding to the size of the window.
When the window size is increased, the content inside stays low res.
As a workaround, I currently output to the maximum height of screen using a batch command like this:
```
@ECHO OFF
setlocal ENABLEDELAYEDEXPANSION
setlocal ENABLEEXTENSIONS
set wmicheight="wmic desktopmonitor get screenheight /format:value"
:height
for /f "tokens=2 delims==" %%a in ('%wmicheight%') do (
If %%a LEQ 1 (
rem skip if height is not bigger than 1
) Else (
rem take the first height value larger than 1
rem then skip to width
Set /a "height=%%a"
)
)
gpac --lowlat=no --buffer=8000 -i out/live.mpd#VR @ compositor:fsize=true:sz=true:osize=%height%x%height%:tvtd=partial @ vout @1 aout
```
Tested with version 7535448f4acd2deaf0400922202f78fc0ae7fb6c on both ubuntu 20.04 (compiled manually) and Windows 11 (installer).

Hello,
I am following example [here](https://github.com/gpac/testsuite/blob/filters/media/python/dash_bind.py) to extend the DASH algorithm. I am aware that I could change the bitrate to fit into the bandwidth conditions.
Unfortunately, I cannot find option to drop (not to download) certain tiles.
Does the python API support dropping tiles ? Or is there any alternative?
GPAC version: version 1.1.0-DEV-rev1555-g339e7a736-master
