we have recently sync our project to bento4 master branch (at today commit 874c264a9d80dcddba0622b489eff25e223609f8)
and a lot of users reported broken DolbyDigital+ and atmos streams
ref. issues https://github.com/xbmc/inputstream.adaptive/issues/1617 https://github.com/matthuisman/slyguy.addons/issues/827
that i can also test/confirm by myself
initially i tried to revert only https://github.com/axiomatic-systems/Bento4/commit/66e29226d27784e39cddc7ff61240087f3618e88 but still broken
then i have reverted to [v1.6.0-641](https://github.com/axiomatic-systems/Bento4/releases/tag/v1.6.0-641) (last working release)
and added on top commits:
b92b7c3042a0f02d233dd5c9b3be2db804670b18
84b95d424c27d1dd7ec503377cab392a9434e8fb
147f15aac87e7cc16a686f1a7f8b10a8549d7508
because i need the c++20 compatibility, and its ok works
then the 3 commits above are not the cause of broken DD
I would not know what other data to provide to investigate the problem
but anyway on the debug there is no bento errors printed nor error raised, silently fails

] | Hello to everyone.
I'm FreeBSD systemn admin but unfortunately,I'm not a programmer. But anyway,I want to understand if I can accomplish a project with my limited resources. What project is this ? I want to watch the protected contents of NowTV using a bhyve virtual machine running with Linux. To be honest,this is an intermediate project,because the main one is to hard for me (watching NowTV using Firefox or Chrome running natively on FreeBSD). I'm studying the situation for several months and I've conducted some experiments to check how can I "hack" it. I realized that I can see the contents only using Windows. Using Linux reports the error "unsupported browser" ; I have applied the Windows 11 user agent on Chrome for Linux but it didn't work. I've applied it even on Chrome for Windows and it worked. So the conclusion is that it wants a real Windows installation. I don't know which kind of checks it does. I don't think that what I want to do can be called piracy or hacking because I'm a regular subscriber of NowTV. I pay my bills every month. But I don't want to be forced to use Windows. My preferred OS are Linux and FreeBSD. I think that you can understand me. Yesterday I've been able to run Chrome 32 bit in a stable way with wine-tkg on Debian. But unfortunately the widevine component does not work and I couldn't watch anything. So. I would like to understand if the bento4 tools can help me with this project,in some way....if they can,I don't know where to start,please put me on the right track. | How to watch the contents of NowTV using Linux | https://api.github.com/repos/axiomatic-systems/Bento4/issues/970/comments | 0 | 2024-06-18T22:28:22Z | 2024-06-18T22:29:15Z | https://github.com/axiomatic-systems/Bento4/issues/970 | 2,360,849,166 | 970 |

] | Hi there, 1st of all thanks for this awesome work !
Since we've 'doxed' it in our [HyMPS project](https://forart.it/HyMPS) (under [VIDEO section](https://github.com/FORARTfe/HyMPS#-1 ) \ [Libraries page](https://github.com/FORARTfe/HyMPS/blob/main/Video/Libraries.md#-- ) \ [Formats](https://github.com/FORARTfe/HyMPS/blob/main/Video/Libraries.md#formats-)), can you please add a GH-compliant license file for it ?
As you know, expliciting licensing terms is extremely important to let anyone better/faster understand how to reuse/adapt/modify sources (and not only) in other open projects and vice-versa.
Although it may sounds like a minor aspect, license file omission obviously causes an inconsistent generation of the relative badge too:
(badge-generator URL: https://badgen.net/github/license/axiomatic-systems/Bento4)
You can easily set a standardized one through the GH's license wizard tool.
Last but not least, let us know how we could improve - in your opinion - our categorizations and links to resources in order to favor collaboration between developers (and therefore evolution) of listed projects.
Hope that helps/inspires ! | [REQ] add a (GH-compliant) license file | https://api.github.com/repos/axiomatic-systems/Bento4/issues/968/comments | 0 | 2024-06-11T15:38:09Z | 2024-06-21T05:55:43Z | https://github.com/axiomatic-systems/Bento4/issues/968 | 2,346,743,930 | 968 |

] | Hello all,
As you know the Widevine team recommends packaging your content using different Content Keys i.e. different keys for Audio, SD, HD, etc. Imagine I have 3 input mp4 files - AUDIO, SD, HD, how could I apply different Content Keys to those during encryption and ensure that the tool generates a valid PSSH box that contains 3 different Key IDs that correspond to Contnet Keys used?
Is it possible with Bento4?
Thank you in advance for your answer! | DRM: Apply different Content Key to different tracks and renditions | https://api.github.com/repos/axiomatic-systems/Bento4/issues/961/comments | 5 | 2024-05-17T12:08:57Z | 2024-06-18T09:12:24Z | https://github.com/axiomatic-systems/Bento4/issues/961 | 2,302,577,433 | 961 |

> InitializationVector SHALL conform to the definition specified in 9.2. Only one Per_ Sample_IV_Size SHALL be used within a file or Per_Sample_IV_Size SHALL be zero when a sample is unencrypted or a Constant IV is in use. Selection of InitializationVector values SHOULD follow the recommendations of 9.2.
The value should be inherited from the `tenc` box:
```
[moov] size=8+911
[mvhd] size=12+96
...
[schi] size=8+32
[tenc] size=12+20
default_isProtected = 1
default_Per_Sample_IV_Size = 8
```
But later in the dump you see that the code guesses (incorrectly) that the value is 0:
[moof] size=8+9781
[mfhd] size=12+4
sequence number = 17494866
[traf] size=8+9757
...
( 0) 3393
[senc] size=12+6400, flags=2
sample info count = 180
IV Size (inferred) = 0
sample info entries:
( 0)
info = []
sub entries:
( 0) bytes_of_clear_data = 515, bytes_of_encrypted_data = 67438087
( 1)
```
This leads to bogus values for the sample entry table | mp4dump decodes `senc` box incorrectly for non-constant IV | https://api.github.com/repos/axiomatic-systems/Bento4/issues/960/comments | 0 | 2024-05-16T15:52:35Z | 2024-05-16T15:52:35Z | https://github.com/axiomatic-systems/Bento4/issues/960 | 2,300,768,957 | 960 |

I have tried all possible combinations however unable to have it working without splitting the file. Only if I use the --smooth option with --no-split the file is not split in to segment and also it uses the time based template. Checking if there is some option that I am missing ?
Here is the smooth example, however it generates additional ism files and it uses following template
`media="stream.ism/QualityLevels($Bandwidth$)/Fragments(video=$Time$)"`
Here is command
`mp4dash -f --smooth /home/sample/a.2.mp4 /home/sample/v10000.2.mp4 /home/sample/v1000.2.mp4 /home/sample/v600.2.mp4 /home/sample/v300.2.mp4 -o /home/sample/mpd --mpd-name=410776960.mpd --no-split`

] | Hello,
I try to create a HLS from an MP4 video input file as well as 1-n audio tracks (AAC) by calling this command
```
mp4hls --output-dir=/tmp/123 [type=audio,+label=audio,+language_name=eins,+language=eins]audio-1.mp4 dev_sample_video_1280x720_1mb.mp4
```
The file `master.m3u8` that is being generated from this command contains an "Audio" section that contains an unspecified language name "Unknown" and language "und". How can this be? I did not specify this audio & language. Where does it come from?
```
# Audio
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac",NAME="eins",LANGUAGE="eins",AUTOSELECT=YES,DEFAULT=YES,URI="audio/aac/eins/stream.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac",NAME="Unknown",LANGUAGE="und",AUTOSELECT=YES,URI="audio/aac/und/stream.m3u8"
```
For other video files that I used, I see additional audio channels like "Ger" and "Eng" that I did not specify as well. I don't know where this comes from and wonder why these information are being added automatically by mp4hls.
Has anyone an idea what the problem could be?

I find that in the AP4_Stz2Atom::AP4_Stz2Atom function, the sample_count obtained through stream.ReadUI08 may lack proper range validation. This can lead to a heap out-of-bounds read when calling AP4_BytesToUInt16BE, triggering a segment fault.

] | Hi on a Kodi software library we are using bento4
but our build system already set the CMAKE_OSX_ARCHITECTURES var
recently with commit https://github.com/axiomatic-systems/Bento4/commit/cbea428ae2f095afeb3c2b6ed25d692c9706de21
has been added this line
https://github.com/axiomatic-systems/Bento4/blob/525027c6ef57bdd26636c9557239e7d559c612ad/CMakeLists.txt#L17
that set the CMAKE_OSX_ARCHITECTURES looks like that overwrite our config value, and cause to failed build of bento4
can you implement a logic to avoid to change/overwrite an existing CMAKE_OSX_ARCHITECTURES value? | build problem with CMAKE_OSX_ARCHITECTURES var | https://api.github.com/repos/axiomatic-systems/Bento4/issues/945/comments | 0 | 2024-03-28T13:58:39Z | 2024-03-28T14:00:47Z | https://github.com/axiomatic-systems/Bento4/issues/945 | 2,213,315,755 | 945 |

] | Hello!
Very similar to #781 but this time there's nothing to use, even more out of spec!
I've attached the init and first segment:
[broken.zip](https://github.com/axiomatic-systems/Bento4/files/14789324/broken.zip)
The keyid/key is f8c80c25690f47368132430e5c6994ce:7bc99cb1dd0623cd0b5065056a57a1dd
Because it's audio the skip/crypt pattern is just 0,0 and from looking at an audio example that does work, the SENC box is very simple just containing the count of samples:
Unfortunately for me, I have tried but failed to create a simple 16 byte box in inputstream.adaptive to contain data: `trun->GetEntries().ItemCount()`
Is this something you can a) implement a fix in AP4_CencSampleInfoTable::Create, or b) advise the in pattern way to create a simple 16 byte SENC box like above?

] | Hi, barbibulle.
I checked your program mp4mux.exe, the command is dv-profile 5 and as a result video.mp4, he created where does Dolby Vision show from? There was also the original without dolby vision, why add it specifically mp4mux.exe --dv-profile 5 create dolby vision? If there is no dolby vision in the video and still --dv-profile 5, then it will not be dolby vision.
mp4muxer.exe version 1.3.3 I specially made --dv-profile 5 --dvh1flag until the end of creating mp4 and there is no Dolby Vision, that's how it definitely gives out cleanly. And you mp4mux.exe --dv-profile 5 false files or something from Dolby Vision.

] | In an environment where disk usage is simulated using memory, I am using mp4decrypt. I attempted to delete the portions of the original file that have already been read during the execution of mp4decrypt. However, I encountered errors in doing so, as some blocks were being read twice. Can you provide some insights into the patterns, such as whether there is an initial random reading of fixed-sized blocks followed by sequential reading of other blocks? | Implementation details about mp4decrypt | https://api.github.com/repos/axiomatic-systems/Bento4/issues/920/comments | 0 | 2024-01-15T09:20:00Z | 2024-01-23T01:15:36Z | https://github.com/axiomatic-systems/Bento4/issues/920 | 2,081,595,353 | 920 |

On `AP4_Movie::AP4_Movie`, parsing tracks and added into m_Tracks list, but it seems that mp42aac cannot correctly delete when we got an `no audio track found` error. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted mp4 file.

] | Hello,
I have encountered an uncommon issue with mp4decrypt, where it successfully decrypts an MP4 file, but the resulting decrypted audio track cannot be played correctly.
Here are the links to the raw audio and video MP4 segment files:
- Raw Audio MP4 Segment File: [Link](https://ufile.io/aqpb7dfi)
- Raw Video MP4 Segment File: [Link](https://ufile.io/vqk8tnuu)
Both tracks share the same decryption key: `49642d2151ac6c3f8453bbfc4b3fdfc0`.
The video segment decrypts successfully and can be played and viewed without any issues (e.g., using VLC).
However, the audio segment does not decrypt correctly, despite mp4decrypt not reporting any errors.
By inspecting the mp4 structure It can be observed that the only difference between those two segments is that audio one does not have senc, saiz and saio boxes at all.

[
"axiomatic-systems",
"Bento4"
] | Hello there,
I encountered an issue while using the mp4dash tool. According to the **ISO/IEC 14496-12** standard, in section **8.8.10 Track Fragment Random Access Box**, it specifies that the maximum number to be represented in the 'time' and 'offset' fields when the version of the 'tfra' box is 0 should be a number represented by 32 bytes (2^32 -1).
The problem arises when adding encryption information to the other mp4 atoms in an input content where the version of the 'tfra' box is 0. If the offset of the output 'tfra' box becomes a number greater than 2^32, according to the standard, it should update the version of the 'tfra' box to version 1 in order to represent an integer up to 2^64.
The command:
```bash
mp4dash --mpd-name my_content.mpd --widevine-header provider:MyProvider#content_id:1 --encryption-key MY_HEX_KEY2 --playready-header=LA_URL:http://test.playready.microsoft.com/service/my_manager.asmx\
my_content_video_Avc_3500_1280x720.mp4\
my_content_video_Avc_1800_960x540.mp4\
my_content_video_Avc_800_640x360.mp4\
my_content_audio_aac_96_es.mp4\
my_content_audio_aac_96_eng.mp4\
-o /my_output_path/cipher/ --verbose --no-split
```
The issue occurs only in the highest layer (3.5mbps) mp4 file, whose original offset of the 'tfra' box is an integer value of 4292674329. When encryption information is added to the rest of the atoms, the value increases to 4301140778 (greater than 2^32), and thus, the number should not be encapsulated in a 'tfra' version 0. However, the software still does it, resulting in errors in some mp4 file reading and analysis programs. This could potentially cause playback issues in some media players. | mp4dash does not update version of 'tfra' atom when it should | https://api.github.com/repos/axiomatic-systems/Bento4/issues/899/comments | 0 | 2023-10-17T08:29:20Z | 2023-10-17T08:30:36Z | https://github.com/axiomatic-systems/Bento4/issues/899 | 1,946,857,469 | 899 |

At first glance, it feels like mp4edit --insert behave like a "replace" box operation rather than append/insert operation.

] | Hello,
I've been trying to get the C++ interface for this program working, and I sucessfully have it reading the metadata from an MP4 file and logging it out.
When I try to remove this metadata, using `entry.RemoveFromFile()` I then need to save the changes, by doing something like `AP4_FileCopier::Write(*input_file, *output);`
Is there a way to do this without making a new file? I've already tried feeding in the `AP4_ByteStream` used to generate `input_file` in this case, but that doesn't seem to work.
Thank you. | Can you edit the metadata on an MP4 file without writing to a different output file? | https://api.github.com/repos/axiomatic-systems/Bento4/issues/889/comments | 1 | 2023-08-21T09:37:46Z | 2023-08-21T19:50:34Z | https://github.com/axiomatic-systems/Bento4/issues/889 | 1,858,990,073 | 889 |

] | The playlist segment lengths were **6s** in playlists I generated in `1.6.0-638` after using the following 2 commands to fragment an mp4 and create the playlist
```
mp4fragment --fragment-duration 6000 input_file intermediate_file
mp4dash --hls --no-split --profile=on-demand -o output_folder -f intermediate_file
```
After running the same commands with the same `input_file` with `1.6.0-639` and `1.6.0-640` the fragment files themselves have been larger than in `1.6.0-638` and the playlists generated have **1s** segment lengths.
| file size | version |
| --- | --- |
| 33504396 | 638 |
| 33508684 | 639 |
| 33508684 | 640 |
I also tried mixing the output from `mp4fragment` to the opposite `mp4dash` command (ex 638 mp4fragment output to 640 mp4dash and vice-versa) and the result was that the fragmented file seems to determine if 1s or 6s playlist segments are generated. So it seems like something changed in the 639/640 version of `mp4fragment` that is causing the playlist segment generation to go from 6s to 1s.
For completeness, here is the source file I was using, and the ffmpeg command I'm using to generate the `input_file` used in the commands above:
Source video: [fire_45s.mp4](https://jgcvideo2020.files.wordpress.com/2023/07/fire_45s.mp4)

] | Hi, I have a question regarding to the frame_rate for video muxing in mp4mux.
I found the parameter frame_rate was introduced many years ago, during which the vps_num_units_in_ticks and vps_time_scale were not parsed.
With the updates of mp4mux, it now can parse VPS to get the real timescale from elementary stream, so I'm wondering what's the use case for keeping this frame_rate?
Thanks! | Question: What's the purpose of #frame_rate in mp4mux | https://api.github.com/repos/axiomatic-systems/Bento4/issues/881/comments | 1 | 2023-07-18T09:25:15Z | 2023-07-24T03:08:31Z | https://github.com/axiomatic-systems/Bento4/issues/881 | 1,809,533,985 | 881 |
