https://radikal.host/i/FBYjPT
The next version is fix. | mp4mux.exe Audio Missing ID_END | https://api.github.com/repos/axiomatic-systems/Bento4/issues/879/comments | 3 | 2023-07-16T09:27:14Z | 2023-08-06T07:34:30Z | https://github.com/axiomatic-systems/Bento4/issues/879 | 1,806,512,393 | 879 |

] | It is confusing about the audio track parameters, in your sample,
AP4_Track* track = new AP4_Track(AP4_Track::TYPE_AUDIO,
sample_table,
0, // track id
sample_rate, // movie time scale
sample_count*1024, // track duration
sample_rate, // media time scale
sample_count*1024, // media duration
language, // language
0, 0); // width, height
If I used it directly in my own code, it usually causes unexpected long duration(exp. 1 minute video shows 40 minutes duration). Hence I modified the code above to
m_nAudioSamples = Audio_Sample_table->GetSampleCount();
AP4_UI64 movie_timescale = 1000;// since video track also uses 1000 as movie_timescale
AP4_UI64 AudioTrackDuration = m_nAudioSamples * movie_timescale;
AP4_UI64 MediaDuration = m_nAudioSamples * movie_timescale;
AudioTrackDuration = AP4_ConvertTime(movie_timescale * m_nAudioSamples, m_sample_rate, movie_timescale);
AP4_Track* track = new AP4_Track(AP4_Track::TYPE_AUDIO,
Audio_Sample_table,
2, //0, // assume video track id = 1, then audio track id = 2
movie_timescale, // movie time scale
AudioTrackDuration, // track duration
m_sample_rate, // media time scale
MediaDuration, // media duration
"und", // language
0, 0); // width, height
Now in this way, the muxer sometimes works, sometimes only have video track, and when probe with ffmpeg, it told me "invalid STSD entries 0".
In order to match video track, what will be the right way to set the following parameters?
movie time scale
track duration
media time scale
media duration
Thanks.

Thanks for fixing the issue #741, but still there is out-of-memory bug in the latest version (1.6.0-640) of multiple programs because of the function AP4_DataBuffer::ReallocateBuffer() at Ap4DataBuffer.cpp:210.
We observed the same bug in mp4info, mp42aac, mp42avc, mp4decrypt, and mp4dump with the same root cause.
Here is the output of program with address sanitizer attached.

https://github.com/glomatico/gamdl/blob/main/README.md
I'm using a apple downloader script above, it uses aria2c.exe, mp4box.exe and mp4decrypt.exe.
I compared the downloaded song from this script to an itunesmatch downloaded version both from the same link, however the audio stream did not match. So I was wondering that did it convert the song after decrypting it? I'm not exactly sure how it works.

] | I recently had a need to mux an AV1 stream to MP4.
In order to create `AP4_Av1SampleDescription`, the information included in the sequence header should be used, but we confirmed that `AP4_Av1FrameParser` does not exist.
In order to solve the problem we are facing right now, we are directly parsing and using the sequence header.
However, I want to maintain a consistent source code by using `AP4_Av1FrameParser` included in libap4 like `AP4_AvcFrameParser`.
I hope you will review it positively. Thank. | Could you please add `AP4_Av1FrameParser`? | https://api.github.com/repos/axiomatic-systems/Bento4/issues/849/comments | 2 | 2023-04-11T01:13:24Z | 2023-06-02T03:11:10Z | https://github.com/axiomatic-systems/Bento4/issues/849 | 1,661,621,042 | 849 |

] | Not sure what version #667 is, but I have the same issue running on version 1.6.0-639 with M2 chip, I have tried to add **+language_name** tag, but didn't help. Someone mention a similar issue under [#659](https://github.com/axiomatic-systems/Bento4/issues/659#issuecomment-1372841466). Not sure if this is a bug after the Apple Silicon build.

] | I have manually set the offsets in the co64 atom.
Because I am recovering a mp4 video file which does not have a moov atom so I'm reconstructing the atoms manually.
Every time when i do:
`mp4edit --replace moov/trak[0]/mdia/minf/stbl/co64:co64.atom moov.atom moov.atom_2`
mp4edit always creates a new mdat and also changes all of the co64 atom values.
How to prevent mp4edit in creating a new mdat atom and also changing the co64 offset values?
Thanks. | How to update/replace the co64 atom without creating a new mdat or changing the co64 atom values after replacement? | https://api.github.com/repos/axiomatic-systems/Bento4/issues/847/comments | 1 | 2023-03-15T07:21:45Z | 2023-05-29T02:34:30Z | https://github.com/axiomatic-systems/Bento4/issues/847 | 1,624,906,572 | 847 |

I was able to remove a co64.atom using the following syntax:
`mp4edit --remove moov/trak/mdia/minf/stbl/co64 moov.atom moov.atom_edit`
However I'm not able to replace or insert a new co64.atom to the same moov.atom file:
`mp4edit --insert moov/trak/mdia/minf/stbl:co64.atom moov.atom moov.atom_edit`

] | Hello.
I have a corrupt h264 mp4 video which does not have a moov file.
I can reconstruct the moov file manually by looking into the mdat atom and using a hex editor to find all the video and audio heuristics relating to start and stop NAL code and also other things like chunk_offset.
I am also comparing moov data from another non-corrupted video file produced from the same camera. This is making things easy to reconstruct the moov file manually for the corrupted mp4 video.
I was able to find about 90% of all of the chunk_offset values in the mdat atom of the corrupted file which does not have the moov file using the hex editor using heuristics.
Now how can I add these chunk_offset values into the co64 atom?
I extracted the co64 atom using mp4extract but have no idea how to modify the values, the hex editor can not recognize any texts of numbers or what not that embeds the chunk_offset's values... maybe I need to change the character encoding?
Here is what the hex editor shows (I'm using "imhex" editor):

A loop was executed within the function, but due to an unknown error, the entry_count variable controlling the rotation of the loop overflowed to 2147483649 (231 + 1). The loop continues, resulting in insufficient memory and the program was killed by the system kernel, resulting in a crash. We think the cause of the dead loop: entry_count is initialized on line 89, and the function that caused the exception to this variable is stream.ReadUI32(entry_count) on line 90. The call to this function causes the entry_count variable to become a very large value, causing an endless loop to occur. | Found a vulnerability in the program（Maybe？） | https://api.github.com/repos/axiomatic-systems/Bento4/issues/835/comments | 0 | 2023-02-27T07:59:28Z | 2023-05-29T02:42:58Z | https://github.com/axiomatic-systems/Bento4/issues/835 | 1,600,669,209 | 835 |

```
$ make install cmake gcc
make: *** No rule to make target 'install'. Stop.
```
There isn't a clean list of `include` files, not a clean `bin/` directory, etc... I would like to reproduce what is offered on the downloads page. Any and all help is greatly appreciated. :bowing_man:

There is an heap overflow in ReadPartial, Ap4StdCFileByteStream.cpp:341, in the newest master branch 5e7bb34a08272c49242196eba1cefab8af55f381, which seems to be incomplete fix of issue #510.
Here is the reproducing command:

[mp4info_overflow_ReadPartial341.zip](https://github.com/axiomatic-systems/Bento4/files/9987970/mp4info_overflow_ReadPartial341.zip)
(unzip first)
The reason of this overflow can causes arbitrary code execution by memory manipulation since user can control the content parsed by the program.

] | Hi,
I'm looking for a way to add new segment to `mp4dash` encrypted (PlayReady) output without re-generating everything from scratch.
My approach was to use `mp4encrypt` with the same key used in `mp4dash` and then to update the `mediaPresentationDuration` field in `stream.mpd` but it does not work - the player detects the new video length but fails to play the last segment and just skips it.
The new segment I'm trying to append is the same size as the ones in the original encrypted video.
My steps are:

] | Hey folks,
I'm very interested in DRM technology as I'm building on a VOD platform. Basically the packaging process is fully done but currently without DRM. As I'm not interested in paying for a DRM provider, I would like to know if it is potentially possible to write your own Key exchange service for that? Or do I really need to pay a license fee here?
Thanks in advance and sorry if this might be the wrong place to ask this qustion.

There is a segmentation fault caused by null pointer dereference in MP4fragment, Ap4StsdAtom.cpp:75 in the newest commit 5e7bb34a08272c49242196eba1cefab8af55f381.
The reason for this issue is that the return value of the GetSampleDescription is unchecked.

] | With multiple video bitrates (specified as multiple MP4 files) in mp4hls, the video segments are written to folders named "media-1", "media-2", and so on. Is there a way to set this name in the optional property name/value pairs in front of the input files? I tried using +label="1000Kbps" but the naming convention stayed the same. I'm using Bento4 mp4-hls.py version 1.2.0r639.

Hello, I use my fuzzer to fuzz binary mp42hevc , the binary all crashede, and shows that allocator is out of memory trying to allocate 0xxxxxxx bytes. Then I use the crash input to test binary mpesplit and mp4tag,and all crashed beacuse of same reason. Here are the details.

] | Hey,
I'm having trouble generating a hls stream with equal segment duration for audio and video.
My first step is to force keyframes on audio and video files every 2 seconds with `ffmpeg`.
```
ffmpeg -t $duration -i original.mp4 -c:v libx264 -an -vf "scale=-1:1080" -b:v 6M -force_key_frames 'expr:gte(t,n_forced*'"$keyframe_interval"')' -r $fps 1080p.mp4
ffmpeg -t $duration -i original.mp4 -c:a aac -vn -force_key_frames 'expr:gte(t,n_forced*'"$keyframe_interval"')' -r $fps audio_1.mp4
```
Then I fragment those two files with `mp4fragment`.
```ps1
mp4fragment --fragment-duration 6000 1080p.mp4 f-1080p.mp4
mp4fragment --fragment-duration 6000 audio_1.mp4 f-audio_1.mp4
```
And finally I create my hls live stream with `mp4dash`.
```ps1
mp4dash -o stream --hls --use-segment-timeline f-1080p.mp4 f-audio_1.mp4
```
This generates the following two playlists (and other stuff of but not important here)
Audio Playlist

```
The problem is, that:
1. Audio and Video segments in the created playlists have not the same length. My goal is to have exactly `#EXTINF:6.0,` on every segment for video and **audio**.
2. Can I limit the or fix the digits for the segment duration. Meaning e.g. max 3 digits as segment length so `#EXTINF:6.013968253968254,` turns into `#EXTINF:6.014,`?
The first point would make the second obsolete. And I guess point 2 is not fixed by rounding the number. | Sync segment duration of audio and video stream with mp4dash | https://api.github.com/repos/axiomatic-systems/Bento4/issues/790/comments | 1 | 2022-10-04T11:24:14Z | 2023-10-01T15:19:06Z | https://github.com/axiomatic-systems/Bento4/issues/790 | 1,396,096,592 | 790 |

"axiomatic-systems",

] | Hi @barbibulle again so soon!
I found a regression introduced by this recent commit (at least I think so)
This audio won't play correctly ([audio.zip](https://github.com/axiomatic-systems/Bento4/files/9692318/audio.zip)), it fails on the second iteration of the loop containing/at this line here: https://github.com/axiomatic-systems/Bento4/blob/6ab668d60a897291644b7e184b1b8a47204cec9e/Source/C%2B%2B/Core/Ap4LinearReader.cpp#L350
Anyway with a little trial and error I think the problem is the new early exit here:
https://github.com/axiomatic-systems/Bento4/blob/6ab668d60a897291644b7e184b1b8a47204cec9e/Source/C%2B%2B/Core/Ap4TrunAtom.cpp#L145-L152
If I rearrange to move the `SetItemCount` before the return to look like this:
```
m_Entries.SetItemCount(sample_count);
int record_fields_count = (int)ComputeRecordFieldsCount(flags);
if (record_fields_count == 0) {
return;
}
if (bytes_left / (record_fields_count*4) < sample_count) {
return;
}
```
Then all is good and playback is restored.
Not sure if this line should move all the way up before any of the introduced return statements?

Using master branch...
My code is more or less the same as in mp4encrypt app main function. I have linked the library into my multi-threaded application that can execute many threads simultaneously. If I execute only 1 thread, everything seems to works just fine. If I execute many threads I get the assertion below... (always reproducible after running for a short while)

] | Hi again
The attached zip contains the init and a segment from an audio track of a CBCS encrypted stream:
[audio.zip](https://github.com/axiomatic-systems/Bento4/files/9674419/audio.zip)
This decrypts successfully in browser/official app, but bento4/Kodi/inputstream.adaptive is not currently handling this properly.
When trying to create a sampleinfotable it's missing data because there's no SAIZ/SAIO boxes, and the SENC box is effectively empty:
This here actually creates the sampleinfotable: https://github.com/axiomatic-systems/Bento4/blob/5b7cc2500d514717a64675fcf631939494c074ce/Source/C%2B%2B/Core/Ap4CommonEncryption.cpp#L2828-L2838
But m_sampleCount is 0 (and probably more data missing too), no IVs are stored and ultimately calling DecryptSampleData fails here: https://github.com/axiomatic-systems/Bento4/blob/5b7cc2500d514717a64675fcf631939494c074ce/Source/C%2B%2B/Core/Ap4CommonEncryption.cpp#L2127
I'm hoping you can help with a solution or at least point me in the right direction. I've been at it for a couple of hours and tried a few things but now getting to the point of needing some help.
Thanks heaps.
edit: btw this is from the same stream/program with incorrect boxes in the video stream from issue #742 | Failing to correctly do AP4_CencSampleInfoTable::Create on particular file | https://api.github.com/repos/axiomatic-systems/Bento4/issues/781/comments | 3 | 2022-09-29T12:15:13Z | 2022-10-02T06:51:25Z | https://github.com/axiomatic-systems/Bento4/issues/781 | 1,390,770,274 | 781 |

Hi, developers of Bento4:
I tested the binary mp4edit and mp42hevc with my fuzzer, and three crashes incurred, including two memory-leaks from mp4edit and a heap-overflow from mp42hevc. And I think Bug1 and Bug2 are different. The following is the details.
# Bug1
Detected memory leaks in mp4edit.

# Notice
I find the two bugs not only exist in latest branch but also exist in latest release version Bento4-1.6.0-639.
The bug1 is similar to the issuse#363([CVE-2019-8378](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-8378)),which means this bug hasn't been fixed now.

Hello, I use my fuzzer to fuzz binary mp4tag , the three binary all crashede, and shows that allocator is out of memory trying to allocate 0xxxxxxx bytes. Then I use the crash input to test binary mpesplit and mp42hevc,and all crashed beacuse of same situation. The version of Bento4 is the latest commit[5b7cc25](https://github.com/axiomatic-systems/Bento4/commit/5b7cc2500d514717a64675fcf631939494c074ce) and the operation system is Ubuntu 18.04(docker). The following is the details.And the issue is different from #342. Beacuse I test the poc,and it didn't work.

] | Hi, there.
There is a segmentation fault caused by null pointer dereference in MP4fragment, Ap4MdhdAtom.cpp:69 in the newest commit 5b7cc250.
The reason for this issue is that the pointer of the parameter language is unchecked.
