] | Hi, I am having similar issue like this post here
https://github.com/axiomatic-systems/Bento4/issues/450
I can decrypt video with key in format 1:key and kid:key and audio only decrypts with kid:key(windows).
When I try replicate the same on ubuntu 18 the audio doesn’t decrypt.
I already tried downloading latest code from this repo and building it but it just doesn’t work.
I followed these steps
git clone
mkdir cmakebuild
cd cmakebuild
cmake -DCMAKE_BUILD_TYPE=Release ..
make
Then tried decrypting using the binary I just compiled. Maybe I am using the wrong binary or doing something wrong?
I am suprised it works on windows and not on ubuntu 18.04.
Any guesses? | mp4decrypt decrypts audio on windows but not on linux | https://api.github.com/repos/axiomatic-systems/Bento4/issues/538/comments | 2 | 2020-07-27T03:11:10Z | 2020-07-29T19:57:20Z | https://github.com/axiomatic-systems/Bento4/issues/538 | 665,942,102 | 538 |

I want t o decrypt a video file in linux with mp4decrypt.
The video file i have must be decrypted with 4 keys...
./mp4decrypt --show-progress --key 2:66b4f4520b9257c1a429b7517deee02f --key 2:ad1dfd6c6929b13ea89a557f9890b410 --key 2:5d63fb5b60e7289b2ca719a4336702e1 --key 2:839ec82f1c0a94e9f8d94bee458cb9e3 videoencrypted.mp4 test_out.mp4
in Linux that wont work.. video is not derypted properly.
In windows with same line/keys all is fine.
Any suggestions ?? | mp4decrypt doesnt decrypt properly in linux when using several keys for one track | https://api.github.com/repos/axiomatic-systems/Bento4/issues/536/comments | 2 | 2020-07-19T10:43:04Z | 2020-07-29T06:07:10Z | https://github.com/axiomatic-systems/Bento4/issues/536 | 660,756,422 | 536 |

] | Hello,
i was trying to read https://www.bento4.com/developers/hls/
but i couldn't understand how i can convert multiple videos to a single master.m3u8 playlist,
So currently i have (same video only quality changes as file name says)
```
root@ffmpeg:/store# ls 1
240p.mp4 360p.mp4 480p.mp4 720p.mp4
```
How would you suggest me to convert these on hls and have only a single master.m3u8 ?
i was thinking to convert them one by one and then manually merge playlist .m3u8 files to a single master.m3u8 file but i was thinking maybe there's some different easier method ?
Thank you. | convert multi bitrate on a single master.m3u8 | https://api.github.com/repos/axiomatic-systems/Bento4/issues/533/comments | 0 | 2020-07-14T11:27:15Z | 2022-04-25T12:18:01Z | https://github.com/axiomatic-systems/Bento4/issues/533 | 656,539,819 | 533 |

I have tried with the following methods:

I have encoded with ffmpeg and fragmented with mp4fragment tool with 4000 fragment duration. Could any one suggest me the correct way to do this.
Additional notes:

I am opening an AP4_FileByteStream from a *.m4a file, which contains chapter markers.
I then open a AP4_File using the above stream.
I then save the size of the moov atom *(GetMovie() -> GetMoovAtom() -> GetSize())
All is good, no problem here.
I then proceed to save the opened stream to a new file with AP4_FileCopier::Write
This is the method to save to the new file
```
bool MP4FileWrapper::saveTo(const char* szOutputFileName) {
bool success = false;
assert(this->isOpen() && szOutputFileName);
if (this->isOpen() && szOutputFileName) {
// create the output stream
AP4_ByteStream* pOutputStream = NULL;
AP4_Result result = AP4_FileByteStream::Create(szOutputFileName, AP4_FileByteStream::STREAM_MODE_WRITE, pOutputStream);
assert(AP4_SUCCEEDED(result));
success = AP4_SUCCEEDED(result);
if (success && pOutputStream) {
// adjust the chunk offsets if the moov is before the mdat
if (this->m_moov && this->m_pAP4_File->IsMoovBeforeMdat()) {
AP4_LargeSize new_moov_size = this->m_moov->GetSize();
AP4_SI64 size_diff = new_moov_size - this->m_moov_size;
if (size_diff) {
this->m_moov->AdjustChunkOffsets(size_diff);

success = AP4_SUCCEEDED(result);
assert(AP4_SUCCEEDED(result));
delete pOutputStream;
}
}
return success;
}
```
After this the new m4a file does not show chapter markers anymore.
I'm attaching the before (with-chapters.m4a) and after (no-chapters.m4a) files here.

] | I build mp4dump myself from master branch code. The relative issue is [issue 505](https://github.com/axiomatic-systems/Bento4/issues/505). It seems that this fix introduces a new bug here. As far as I know, the old version mpd4dump works.
user data in mp4:

Extra Data:
Description: Access violation near NULL on source operand
Short description: SourceAvNearNull (16/22)
Explanation: The target crashed on an access violation at an address matching the source operand of the current instruction. This likely indicates a read access violation, which may mean the application crashed on a simple NULL dereference to data structure that has no immediate effect on control of the processor.

Description: Heap error
Short description: HeapError (10/22)
Explanation: The target's backtrace indicates that libc has detected a heap error or that the target was executing a heap function when it stopped. This could be due to heap corruption, passing a bad pointer to a heap function such as free(), etc. Since heap errors might include buffer overflows, use-after-free situations, etc. they are generally considered exploitable.

Explanation: The target crashed on an access violation at an address matching the source operand of the current instruction. This likely indicates a read access violation, which may mean the application crashed on a simple NULL dereference to data structure that has no immediate effect on control of the processor.

] | I've recently found on my hard drive some (10) mp4 files that I copied from my android phone (recorded with it) that are either 2,83GB or 6,63GB.
I really don't know what caused these file sizes (maybe a virus, antivirus doesn't find anything strange).
dumping the information I can see typical atoms but at the end there are strange "no names" atoms, represented with [...] (three dots), other software puts direcly no name to them.
```
[mdat] size=16+26488377
[....] size=8+1966620317
[....] size=16+4843859375
```
I would like to use mp4edit to remove that strange empty (all zeroes) atoms, but it says that ... is invalid atom.
How can I do it?
Edit, i tried (and all failed with ERROR: atom not found):
mp4edit.exe --remove ""
mp4edit.exe --remove [...]
mp4edit.exe --remove ...
mp4edit.exe --remove [3] (third item)
Edit2: For now what I did is that I run mp4fragment with input and output and no other argument over all the files and it seems it copied audio and video without fragmenting. I'm keeping original files just in case I'm able to delete those strange atoms. | Huge files containing atoms without name (..., three dots) | https://api.github.com/repos/axiomatic-systems/Bento4/issues/502/comments | 2 | 2020-05-04T18:24:00Z | 2020-05-05T05:33:44Z | https://github.com/axiomatic-systems/Bento4/issues/502 | 612,074,925 | 502 |

] | I've been trying to rebuild the MOOV / Movie header for an Encrypted stream through bento4, it works fine with AVC context but with HEVC it seems the Codec Private Data doesn't parse correctly it seems and the hvcC configuration seems seems to be all wrong. The chroma depth and luma depth are wrong and the Profile Compatibility and Constraint are also incorrect. The codec private data is this `0000000140010C01FFFF01600000030090000003000003009695940900000001420101016000000300900000030000030096A001E020021C596565924C2F01520202020800001F480002EE0040000000014401C172B66240`
I have no issues at all using //AP4_AvccAtom* with FourCC / AVC1 codec private data, it builds perfectly fine however when using //AP4_HvccAtom* no colour space is added to the stream, it's not visible in mediainfo and neither is the HEVC Profile and Level. Not sure what the issue is but would be great if someone could investigate this?

] | i am using mp4hls command inside a Java program to encrypt a video file into .m3u8 format using AES-128 encryption and using single segment file. I need to create multiple bit rates from single video file and then encrypt them using AES-128 bit to create m3u8 file so that i can use adaptive bit rate features of HLS Player. Till now i was using mp4HLS command which was taking a single input file and providing output file. Is there a way through which mp4HLS can take single video file as input and create multiple output directories for multiple bit rates and put encrypted files in those directories alongwith m3u8 and other files.. Or do i need to use combination of tools to first create multiple bit rates files and then use mp4HLS to encrypt them..I am using these encrypted files for streaming.. | How to create multiple bit rate files using Mp4HLS | https://api.github.com/repos/axiomatic-systems/Bento4/issues/487/comments | 1 | 2020-04-10T18:49:36Z | 2020-04-26T00:43:25Z | https://github.com/axiomatic-systems/Bento4/issues/487 | 598,037,740 | 487 |

We're trying to do dash packaging with multi-bitrate video encoding with vp9 and vorbis/libopus codecs.

When encoding videos with ffmpeg one pass and doing it's packaging, generated segments doesn't play audio even though audio tracks are present.
```

I'm trying to package a video which have 10 audio tracks in 5 different languages (en, da, no, fi, sv) each having it's stereo (2) and surround (6) track with aac codec. When packaging is done, dash manifest is generated properly but hls playlist file only contains 5 audio track information whereas it should be 10. Video contains following audio tracks
```
{
"Audio": [
{
"language": "en",
"channels": 2,
"codec": "aac"
},
{

"channels": 6,

"channels": 6,

{

"channels": 6,

},
{

"channels": 2,
"codec": "aac"
},
{
"language": "sv",
"channels": 6,
"codec": "aac"
}
]
}
```
While debugging I've found `SelectAudioTracks` method groups audio tracks based on codec whereas grouping of such audio tracks should be based on codec as well as number of channels
**mp4-hls.py**
```
def SelectAudioTracks(options, media_sources):
# select tracks grouped by codec
audio_tracks = {}
for media_source in media_sources:
# pre-process the track metadata
for track in media_source.tracks:
# track group
track.group_id = ComputeCodecName(track.codec_family)
# track language
remap_language = media_source.spec.get('+language')
if remap_language:
track.language = remap_language
language_name = LanguageNames.get(track.language, track.language)
track.language_name = media_source.spec.get('+language_name', language_name).decode('utf-8')
# process audio tracks
for track in [t for t in media_source.tracks if t.type == 'audio']:
group_id = track.group_id
group = audio_tracks.get(group_id, [])
audio_tracks[group_id] = group
if len([x for x in group if x.language == track.language]):
continue # only accept one track for each language per group
group.append(track)
return audio_tracks
```

--hls-master-playlist-name=pl.m3u8 \
video_frag.mp4
1. content_id, is it provided by a third-party drm service, or is it an arbitrary hexadecimal value?
2. this: --encryption-cenc-scheme = cbcs refers to samples aes encryption? If the answer is yes, I want to know when playing the content, just pass the widevine url to activate for the contracted drm service?
In addition, a key.bin file is not necessary to reproduce the content? Well, I don't see any option in mp4dash to create that file as in mp4hls.

The screen remains gray and the video does not play.
I made a network capture of the communication, and even though the Ruby web
server claims that all 2114710 bytes of seg-1.m4s are streamed, the client
actually closes the connection after 860 KB (sending FIN, ACK). I suspect the
iOS player either crashes or atleast makes a hard exit.
I have included the network capture as ios.pcap in the provided ZIP file.

The library uses the AP4_GlobalOptions to have some options like "mpeg-cenc.encryption-layout" in AP4_CencAdvancedSubSampleMapper.
The AP4_GlobalOptions is a singleton and it is not thread safe.
It limits the library to be used from one thread only (or with thread locking on top of the library) or not change the options at all.
It would be better to refactor the code and change AP4_GlobalOptions to be AP4_Options with no static functions.
Then pass a separate instance to the AP4_CencEncryptingProcessor constructor or create it inside AP4_CencEncryptingProcessor and expose it through a GetOptions() function.
The current solution is also reported by valgrind as a memory leak because of the global list of option entries. (AP4_GlobalOptions::g_Entries)
As far as I can see the only place where this class is used is:
https://github.com/axiomatic-systems/Bento4/blob/8f18fa7bc907997ac40d1c53b795ce05c9c070c3/Source/C%2B%2B/Core/Ap4CommonEncryption.cpp#L217
The AP4_CencAdvancedSubSampleMapper instance is created in AP4_CencEncryptingProcessor::CreateTrackHandler() so it would not be hard to propagate the new non singleton options instance.

] | Hello, I am new using bento4, so far I have been able to convert a .mp4 video to hsl with .ts fragments using bento4, in addition to that I have managed to encrypt it with Aes sample, but the reason for my query is that I wish to convert that same video With the same command that I am using in several video qualities: 720p, 480p, 360p, I have reviewed the bento4 page but I cannot find a command that can help me with this.
I found this on the web:
mp4hls --output-single-file video_00500.mp4 video_00800.mp4 video_01100.mp4
But it's very ambiguous for me, I don't know if it's what I'm looking to do, nor do I know how to do it. so any help or guide you can illustrate, I would appreciate | help!

] | I'm having to insert a 'pssh' box into 'moof' box of each fragment of fMP4.
Is there a way to do it using mp4encrypt or mp4edit ?
I tried the following mp4edit command to insert 'pssh' from an external file.
_./mp4edit --insert moof/pssh:pssh.extracted input.m4v output.m4v_
But the above command inserted a new 'moof' (with 'pssh') in addition to the existing 'moof' (instead of inserting 'pssh' into the existing 'moof' )
[ See a part of mp4dump output below ]
_[moof] size=8+70
[pssh] size=12+58, flags=3e
system_id = [70 73 73 68 00 00 00 00 ed ef 8b a9 79 d6 4a ce]

[saio] size=12+8
entry count = 1
[senc] size=12+2164, flags=2
sample info count = 90
[mdat] size=8+98427_
Obviously, above is not the desired format.
Issue reported here https://github.com/axiomatic-systems/Bento4/issues/15 seems to indicate that mp4edit doesn't support insertion/removal of atoms outside of fragments.
Please clarify.

] | Hello!
It would be nice to have an ability to explicitly specify dash representation_id, so we can control directories structure and can reuse result of each mp4dash invocation.
This feature can be used for creating separate playlists for separate codecs (this is required for some old devices, which can not play multicodec playlists).
Also it's will let to control path, so some path based cdns can be configured.
What do you think about it?

] | Hello there,
I'm using mp4info trying to decrypt some ATMOS audio. I got the key itself but it still won't decrypt.
I did mp4info --verbose ATMOS.mp4 and the Keyid was all 00000000000000000000000000000000 so I did something like 00000000000000000000000000000000:01782373000000000000000000002222 for example, but that file still won't be decrypted.
Can the shown KID be different or wrong somehow?

] | Hello,
I am trying to implement custom dash player. The same key id is used for both audio and video as it can be observerd in the sample below. Both audio and video are mp4. The Content Protection of audio and video is described equally in mpd xml document. I am using Bento4 mp4decrypt for decrypting. As a result i got video without audio. But there is no error saying that audio is not decrypted well, it just silently fails. I am playing with this for a while but I am still rookie in this area. I don't know what am I missing.
Any ides what causes output without audio?

] | Hi all
I'm doing a dash decrypt with mp4decrypt, on windows its working perfectly, takes about 90s and then the decryption is complete
On Linux it just finishes instantly but the output file is identical to the input, no decryption has occured, its just a copy of the original file
I've tried 3 different boxes Debian/Ubuntu, I've tried older builds, I've tried precompiled, I've tried compiling, all the same result
My mp4decrypt syntax is as follows
mp4decrypt --key 12345678910111213141516171819202:12345678910111213141516171819202 --key 12345678910111213141516171819202:12345678910111213141516171819202 --key 12345678910111213141516171819202:12345678910111213141516171819202 input.mp4 output.mp4 --show-progress
I'm not sure if this is a bug or I'm missing something obvious
Thanks for any input

] | Multiple uninitialized use on heap are detected in mp4info.
git commit: 7242177
Because there is too much output from Valgrind, so I just select error information of unique buffers based on the stack trace of the allocation point in program, PoC to trigger uninitialized use of different buffers are attached.
To trigger these uninitialized use and get the error information:
valgrind ./mp4info --verbose --show-layout --show-samples --show-sample-data PoC

git commit: 7242177
Because there is too much output from Valgrind, so I just select error information of unique buffers based on the stack trace of the allocation point in program, PoC to trigger uninitialized use of different buffers are attached.

] | Hello dev team,
I am quite new to MP4 container and this library. I would like to know how to:
1) Append more video data to end of an existing track of a mp4 file? Assume that new
video data is encoded using same parameters as used for existing data.
2) Append more video track to an existing mp4 file without creating a new file?.
Thanks. | How to append more video stream to an existing mp4 file? | https://api.github.com/repos/axiomatic-systems/Bento4/issues/439/comments | 0 | 2019-10-07T04:44:18Z | 2019-10-07T04:44:18Z | https://github.com/axiomatic-systems/Bento4/issues/439 | 503,229,941 | 439 |

I am trying to generate a fmp4 DASH Widevine DRM with the CBCS protection scheme.
Only "sample count" in "saiz" AUDIO track shows 0 instead of 243 and exoPlayer is having a problem.
Do you know how to resolve this? Thank you for your support.

] | Hi,
I'm using below command, it's able to generate required files for hls stream and also generates 'key.bin'
`mp4hls "D:\file.mp4" --output-single-file --encryption-mode="AES-128" --encryption-key="22b44eee1236cf62f3b655b17fb31f33" --output-encryption-key`
When I open 'key.bin', it's content is
`"´Nî6Ïbó¶U±³ 3`
As I'm a c# developer, tried using below code to get value similar to key.bin
// c# code
`byte[] data = new byte[] { 0x22, 0xb4, 0x4e, 0xee, 0x12, 0x36, 0xcf, 0x62, 0xf3, 0xb6, 0x55, 0xb1, 0x7f, 0xb3, 0x1f, 0x33 };`
`string ascii = Encoding.ASCII.GetString(data);`
`Console.WriteLine(ascii);`
// but result is as below, its not matching to key.bin
`"?N?6?b??U?? 3`
Im just stucked here, can someone help me.

[
"axiomatic-systems",
"Bento4"
] | Wanted to confirm if `Bento4` is able to repackage a mp4 file with Dolby Vision track to the DASH format with CENC encryption.
Didn't find it from the document, but by searching in the source code, it seems Dolby Vision is already supported.
Tried using `mp4fragment` and `mp4-dash.py` to repackage a Dolby Vision mp4 file into DASH format, and it seemed to be working fine (the codec of the Dolby Vision track used is in form of `dvhe.xx.xx`).
However after enabling the CENC encryption, the created DASH stream became un-playable. By checking the generated video segment, it appears that `Full Sample Encryption` was used instead of `Subsample Encryption` for the video track. And this is aligned with the current implementation:
https://github.com/axiomatic-systems/Bento4/blob/v1.5.1-628/Source/C++/Core/Ap4CommonEncryption.cpp#L1629
I guess the full support of Dolby Vision is not ready yet, at least the CENC encryption is not enabled for it.
Please kindly clarify if any understanding here is wrong. If not, is there a plan to add the CENC support for Dolby Vision. | CENC support for Dolby Vision track | https://api.github.com/repos/axiomatic-systems/Bento4/issues/425/comments | 2 | 2019-08-28T08:21:12Z | 2019-10-08T05:17:04Z | https://github.com/axiomatic-systems/Bento4/issues/425 | 486,228,458 | 425 |

] | H! - We are choosing between using Bento4 or Shaka Packager for the future. We like Bento4 a lot, and might also be ready to eventually contribute with bug-fixes and so on in the future. We respect all the work that has gone into the project, and what it is capable of, and really appreciate it as is - but one thing that is making us doubtful in using it, is the handling of PR:s. There is quite a few unanswered ones as of now. This makes us think about the future project health - are there any thoughts of adding more maintainers in the future, and also, how it is maintained - on a spare-time level, or with real office-time? And, are there any bigger future plans for the project, or is it mainly low-level maintenance? Discussion and response to PR:s might be critical for us in choosing the packager to use for us. Thanks for the work already done in this Open Source-project.. | Question: Regarding project health | https://api.github.com/repos/axiomatic-systems/Bento4/issues/421/comments | 2 | 2019-08-15T08:13:41Z | 2019-08-22T08:10:44Z | https://github.com/axiomatic-systems/Bento4/issues/421 | 481,043,456 | 421 |
