] | For example using Big Buck Bunny:
'MP4Box bbb_sunflower_1080p_30fps_normal.mp4 -edits 1=re0.1-5,0.1 -out tmp.mp4'
Gives the following results in 'MP4Box -disox':

</EditListBox>
</EditBox>
```
The 2nd EditListEntry duration is not 5 seconds, but 0.5 seconds. MediaTime is correct.
I think this is due to an extra scaling operation [here](https://github.com/gpac/gpac/blob/6b5bdbc7f88eb11aa65657ebb97269c11a07711a/applications/mp4box/fileimport.c#L544) where the duration is scaled by ```movie_time.den```

Here is the trace reported by debugging. We can see that the `memcpy` function is called on line 1053 of `utils/bitstream.c`, which will copy the contents of the second parameter `data` to the buffer pointed to by the first parameter. Unfortunately, in this trace the `data` is 0 (NULL), causing the program to crash.

```
I tracked the null assignment of `data` in `isomedia/box_code_base.c`. `data2` is initialized to NULL in line 12743. When the value of `prop_size` is greater than 4 ( line 12764 ), the program will allocate a memory chunk to `data2` ( line 12769 ). Otherwise, `data2` will remain NULL and will be assigned to `tag->prop_value` in line 12777.
In my crash, `prop_size` was set to 1 causing `tag->prop_value` to be NULL. The `tag` is then added to `ptr->tags` for subsequent access ( line 12779).
https://github.com/gpac/gpac/blob/5d68ccd1fa4a5a76cf8db31a33cfb4a2fe2bd4ad/src/isomedia/box_code_base.c#L12736-L12786
When the program executes to `xtra_box_write`, it will get a `tag` from `ptr->tags` ( line 12801 ), and pass `tag->prop_value` to the second parameter of `gf_bs_write_data` ( line 12814 ), which eventually results in `data` being NULL.
Although the program judges whether `tag->prop_value` is 0 in line 12805, it does not change the execution flow of the program and the value of `tag->prop_value`.
https://github.com/gpac/gpac/blob/5d68ccd1fa4a5a76cf8db31a33cfb4a2fe2bd4ad/src/isomedia/box_code_base.c#L12791-L12817
Hope my analysis will help.

With this video file, the file collected by the MP4MUXER program (DLB_MP4BASE \ MP4MUXER) from the same components (H265 and AC3) is determined on the built-in Sony TV player as a full Dolby Vision.
Comparison Output MP4Info (Bento4 \ Mp4Info) on the problematic and normal files showed that the difference in them is only that the file made using MP4Box does not have the "in-movie" and "in-preview" flags in contrast to the file, Made using MP4MUXER.

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
I am using a video for ABR development with segment size as 1000ms and chunk(or frag) size as 200ms.
I need to get size (in bytes) for individual chunks and my idea was to use MP4Box to segment my video and use the file size of the **.m4s** files that would be generated.
The cmd I used below however only generates a file for each segment and not for each chunk. Additionally the mpd file generated has no mention of the frag size I specified which makes me wonder if the current version of MP4Box has support for frags.
`MP4Box -dash 1000 -frag 200 -profile live -out bbb_300/bbb_300.mpd bbb_300.mp4`
Would there be another route that I could take to get the size of individual chunks for the video ? | Getting size of individual fragments(chunks) after segmenting using MP4Box | https://api.github.com/repos/gpac/gpac/issues/2056/comments | 6 | 2022-01-21T04:40:33Z | 2022-01-24T08:12:12Z | https://github.com/gpac/gpac/issues/2056 | 1,110,050,071 | 2,056 |

source.mp4 has TWO audio tracks
I'm trying to get the track #2 from source.mp4 and input it into my working.mp4 output
I can get it to actually get this done, however, it sets all of the track ID's out of order. Instead of them being **Video 1, Audio 2, SRT 3**, it becomes **Video 1, audio 3, srt 4**
If I swap Audio from 3 to 2 with -set-track-id 3:2 then srt will still be 4.
Is there a better way of doing this? I can't seem to find a work around that is accurate.
I simply would like to be able to import video file, import audio (select which track I want out of the audio, in this case there is 1 video track and two audio tracks, I just want to get audio track 2, which would be ID 3), import srt, import chapters and them output in the correct format 1, 2, 3, etc...
I feel like I'm using the CLI wrong in some way. Thank you!

I noticed that the xml dump of file with a `CompactSampleGroupBox` results in invalid xml where `Pattern` tags are never closed.
How to reproduce:
```shell
curl https://conformance.mpeg.expert/ISOBMFF/under_consideration/compact_sample_groups/samplegroups_defrag_compact.mp4 -O
MP4Box -diso samplegroups_defrag_compact.mp4
```
run xml validator on `samplegroups_defrag_compact_info.xml`
Used MP4Box - GPAC version 1.1.0-DEV-rev1632-gf2fddd04-master
btw. is there a way to automate xml validation checks? Could be useful to identify those types of issues when dumping the xml. | ISOBMFF conformance suite issue | https://api.github.com/repos/gpac/gpac/issues/2053/comments | 1 | 2022-01-17T22:03:24Z | 2022-01-18T09:31:59Z | https://github.com/gpac/gpac/issues/2053 | 1,106,292,774 | 2,053 |

I convert a rtmp stream to ll-hls . then stream it with apache httpd .
./gpac -i 'rtmp://:1935/live/abc:gpac:rtmp_listen=1' -o live.m3u8:gpac:segdur=6:cdur=1:profile=live:dmode=dynamic:rdirs=outdir:llhls=sf:hlsc=true
GOP is 150 , fps is 25, generate segment each 6s. and generate small segment each 1s
it plays well in https://www.theoplayer.com/ll-hls-test-page and https://hls-js.netlify.app/demo/ latency is about 5s
but when it plays in safari , its latency is very big. more than 18s.
I wonder why is that, is something missing?

Issue is that libraries will not load because libmediandk.so is not found. App is supposed to work with my version of android (17) but research suggests that libmediandk is only available in android 21+. Is jellybean supported or not?

] | Hi team,
Some crashes were found while fuzz testing of the MP4Box binary which can be triggered via malformed MP4 files. Although these malformed files only crash the program, they could potentially be crafted further into security issues where these kinds of files would be able compromise the process's memory through memory corruption, so hardening the code to prevent these kinds of bugs would be great to mitigate such issues.
See details below for repro and debug information.
Repros uploaded [here](https://www.mediafire.com/file/yvtcsv8y8yxf746/gpac-crashes.zip/file) to the GPAC file drop along with the [mp3](https://www.mediafire.com/file/slmlm3r7xqpqtr7/test.mp3/file) used for testing.

] | Is this kind of key rotation considered in gpac drm packaging?
Segment files may have PSSH(playready pro object, els key object) table.
**Key rotation with ROOT/LEAF keys**
_Changing the encryption keys frequentlyβscalable key rotation_
https://docs.microsoft.com/en-us/playready/packaging/content-packaging-and-delivery
https://github.com/MicrosoftDocs/PlayReady/blob/main/Docs/Packaging/how-to-package-mp4-based.md
>
> There is an advanced mechanism in PlayReady called scalable key rotation (as opposed to license rotation). This method stores an Embedded License Store (ELS) in the stream of the actual content. In this mechanism, the key used to encrypt the A2 segment itself is called the leaf key {kidA2, ckA2}, and is delivered in the ELS of the segment A2, being itself encrypted with a separate key that is the same for all the segments of track A, called the root key {kidRA, ckRA}.
>
> Let's say this asset is live linear TV. When the client attempts playback, it finds kidRA in the PlayReady Header of the stream manifest, and requests a license for kidRA. The License Server returns a root license for the root key {kidRA, ckRA}. Then the client parses segment A1 and discovers the ELS in the header of the segment. Parsing this ELS, it finds the leaf license {kidA1, ckA1} in this ELS. Using the root key {kidRA, ckRA} and the leaf license {kidA1, ckA1}, it can get the value of ckA1, and decrypt and render the segment A1. | Key rotation with ROOT/LEAF keys instead of new <Period> on each new keyID | https://api.github.com/repos/gpac/gpac/issues/2043/comments | 5 | 2022-01-14T11:06:45Z | 2022-01-27T08:22:06Z | https://github.com/gpac/gpac/issues/2043 | 1,103,477,465 | 2,043 |

I need to push living stream by `obs`, and cut living stream into ll-hls segment files. I read `wiki` and using next command to realize this mission:
```shell
gpac -i rtmp://localhost/live reframer:rt=on @ -o res/live.m3u8:segdur=10:cdur=1:profile=live:dmode=dynamic:llhls=sf
```
but `gpac` output next message:
```shell
[FFDmx] Fail to open rtmp://localhost/live - error Input/output error
Failed to load filter for "rtmp://localhost/live": Feature Not Supported
```
I want to know where there is a way to create living stream by `obs` and generate ll-hls segment files? I read wiki and it's just using file as input, which is not true live stream and not people always wanto to do.
| can gpac convert RTMP to ll-hls? | https://api.github.com/repos/gpac/gpac/issues/2037/comments | 3 | 2022-01-07T05:59:47Z | 2022-01-21T18:44:00Z | https://github.com/gpac/gpac/issues/2037 | 1,096,012,181 | 2,037 |

I am trying to encrypt and dash an audio stream packaged in mp4 container using gpac. However, the segments produced by gpac contains corrupted isobmff boxes.
Encryption type used: cenc (common encryption) with the DRM.xml file containing key and kid pair.
The gpac command used to generate the mpd and the segments is:
gpac -i ass1-cenc-1.mp4:FID=A1 cecrypt:cfile=DRM.xml:SID=A1:FID=A2 -o stream.mpd:profile=live:muxtype=mp4:segdur=2:cdur=2:cmaf=cmfc:tpl:stl:template="$File$-Seg-$Number$":SID=A2
The isobmff boxes in the initialisation segments seems fine. However, following issues are seen with the segments:
β’ segments donβt contain a proper styp box at the beginning.
β’ Decoders canβt read the segments if the styp box is corrupted.
β’ On patching styp box some other boxes like senc still show corruption.
GPAC version used: version 1.1.0-DEV-rev1540-g6eb2032c-master

How to reproduce:
MP4Box -itags title="Some title":gen=Genre test.mp4
MP4Box -info test.mp4
Shows tag title has value **Some title:gen=Genre**
Issue is the same omitting quotes (ie MP4Box -itags title=Sometitle:gen=Genre test.mp4 has the same problem)
However MP4Box -itags gen=Genre:title="Some title" test.mp4 works fine. | MP4Box itags string parsing issue with @tag | https://api.github.com/repos/gpac/gpac/issues/2031/comments | 1 | 2022-01-05T03:33:23Z | 2022-01-05T09:21:39Z | https://github.com/gpac/gpac/issues/2031 | 1,093,946,502 | 2,031 |

However all these fail with "Error assigning tag comment=: Bad Parameter":

"gpac",
"gpac"
] | This is not a bug per say - it's a question on how to use gpac/MP4Box to re-combine photo+depthdata into an HEIC file.
- [X] I looked for a similar issue and couldn't find any.
- [X] I tried with the latest version of GPAC.
- [X] I give enough information for contributors to reproduce my issue - An HEIC photo with depth map - https://drive.google.com/file/d/17-1If40KBVrbMulTZhF4469fWL5MZuVE/view?usp=sharing
So, extracting depth map from HEIC is pretty simple these days - heif-convert does it for free when you do a conversion, spitting out everything that is inside an HEIC file, from depth maps to semantic segmentation maps.
On the HEIC image I'm sharing on google drive link above (yes, I need to trim my beard!! LoL), you can run `heif-convert 0089.HEIC 0089.jpg` and it will spit out not only the depth map, but also a few semantic segmentation masks for skin, hair, glass, etc. Also, `heif-info 0089.HEIC` will output this:
```
MIME type: image/heic
image: 2316x3088 (id=36), primary
thumbnail: 240x320
color profile: prof
alpha channel: no
depth channel: yes
(480x640)
z-near: undefined
z-far: undefined
d-min: 0.149780
d-max: 3.218750
representation: uniform disparity
disparity_reference_view: 0
```
> note the depth map data is actually attached in the HEIC file as `depth channel`... it is important to be able to re-create the HEIC with depth data in the actual `depth channel` as this image have, not just like an extra image like segmentation masks are!
What I'm trying to do now is re-create the HEIC file, with the original RGB color image AND the original depth map stored in the actual depth channel of the new HEIC file.
From the documentation and examples, it seems MP4Box may be able to do this, but I couldn't find any documentation explaining how to do it, so I'm not sure if it can at this point.
The whole reason I'm trying to do this is so I can edit the photo image, masking out regions of it to use with photogrammetry, but I need to re-combine the depth into a HEIC file so apple's new photogrammetry api on Reality Kit can "see" the depth data and use it to scale the model correctly.
I'm sorry for logging this question as a bug, but I really want to ask this to you guys, and didn't know where I could ask but here.
Thanks for any insight! I really appreciate!

"gpac",
"gpac"
] | Hi, I am trying to ingest a RTSP stream using GPAC, however, everytime I am trying, I get the following error:
`[RTSP] Error processing user command Network Unreachable`
Here are the commands used:
# to run the rtsp server
`docker run --rm -it --network=host aler9/rtsp-simple-server`
# ffmpeg sending a looped stream to the server
`ffmpeg -re -stream_loop -1 -i test_30fps.mp4 -c copy -f rtsp rtsp://localhost:8554/mystream`
# GPAC grabbing the stream from the server and putting it into an MP4 file:
`gpac rtpin:src=rtsp://192.168.1.32:8554/mystream:gpac:ifce=wlp92s0:FID=SOURCE reframer:rt=on:SID=SOURCE:FID=REGULATED @ -o out.mp4 -graph -logs=all@info -log-file=rtsp.log`
Of course, using ffplay works perfectly
`ffplay rtsp://192.168.1.32:8554/mystream` => has no issue
All the files for this issue are here:
- server.log is the server of the rtsp server https://github.com/aler9/rtsp-simple-server
- rtsp.log is the log of the GPAC command
Configuration:
Ubuntu 21.10
GPAC version 8b22f0912dc91603136e0ddb3d2b583cb04d2c35 compiled manually following the instructions on the wiki

I belong to an open source security research community, and a member (@aidaip) has found an issue, but doesnβt know the best way to disclose it.
If not a hassle, might you kindly add a `SECURITY.md` file with an email, or another contact method? GitHub [recommends](https://docs.github.com/en/code-security/getting-started/adding-a-security-policy-to-your-repository) this best practice to ensure security issues are responsibly disclosed, and it would serve as a simple instruction for security researchers in the future.
Thank you for your consideration, and I look forward to hearing from you!

Is there a way to actually mux dolby vision encoded files with mp4box? I have been trying for hours, I keep coming across threads with alternative ways but none with mp4box. I have no issues muxing to .ts or .mkv and retaining the proper information. However, once I mux it with mp4box it does not retain the proper information.
If I add the code dv-profile=8.1/5 I get "Dolby Vision, Version 0 / SMPTE ST 2086, HDR10 compatible" when it should say something like "Dolby Vision, Version 1.0, dvhe.08.06, BL+RPU, HDR10 compatible / SMPTE ST 2086, HDR10 compatible"
