Playback error with mp4 file (h264 high 5.2 - 2x aac 5.1)

[OpenHT 5]

Emby for android can't play this file when transcoding/remuxing is enabled :

14:33:41.288 [trim for input stream 0:1 @ 0x1f58f00] Channel layout change is not supported
14:33:41.288 Error while filtering: Not yet implemented in FFmpeg, patches welcome

If I force "direct play" by disabling transcoding/remuxing it works fine on my phone.

Thanks!

HI there, please attach the complete emby server and ffmpeg log files. Thanks.

[OpenHT 5]

I've sent you a message with links to the logs and sample file.

Thanks!

[OpenHT 5]

Hi!

Did you have the chance to look into this issue?

Apart from that, is there any way to create custom transcoding/device profiles or edit existing ones? I noticed some wrong decisions when it comes to transcoding or directplay media on certain devices / OSes.

e.g. h264 High L5.2 gets transcoded to Baseline L4.2 although it's natively supported on android & windows (chrome)

Hi, did you explore the stats feature in the video player to learn why it was transcoding?

Thanks for providing the file (privately). The file has an invalid channel layout value set. Since the same is true for both streams, it is unlikely that it became corrupted, - it's rather incorrectly authored.

ffmpeg initially "guesses" the channel layout, because it can't read it:

14:33:41.248 Execution Date: 2023-09-28 14:33:41
14:33:41.280 Guessed Channel Layout for Input Stream #0.1 : 5.1
14:33:41.280 Guessed Channel Layout for Input Stream #0.2 : 5.1
14:33:41.281 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4':

Later, it doesn't get a better result and prints the error

14:33:41.288 [trim for input stream 0:1 @ 0x1f58f00] Channel layout change is not supported

Probably because it considers the channel layout as unknown and this doesn't match the previous "assumption".

 

MPV Player and one other player I tested are playing it but with the wrong audio channels mapped (rear effects channels mapped to R and L) - you can't hear anybody speaking.

VLC plays it correctly, but also indicates that the channel layout indicator is not valid:

Conclusion: File is invalid. Some players play it, some play it wrong and some don't. Emby doesn't, I'm afraid.

Thanks for your help!

I think I found the Problem. I recently switched from ffmpeg 5.x to 6.x which resulted in different audio channel layouts when transcoding eac3/ac3/dts to aac 5.1:

FFMPEG 5
--------
5.1
Stream #0:0[0x1](eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, 5.1, fltp, 383 kb/s (default)
Channel(s)                               : 6 channels
Channel layout                           : C L R Ls Rs LFE

FFMPEG 6
--------
5.1(side)
Stream #0:0[0x1](eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, 6 channels, fltp, 383 kb/s (default)
Channel(s)                               : 6 channels
Channel layout                           : L R C Cb Lb Rb

AAC only supports 5.1 and not 5.1(side) audio channel layout, so I'm not sure why ffmpeg even allows that without throwing an error. Anyway, fixed it by forcing ffmpeg to use 5.1 channel layout instead of 5.1(side).

Would it be a bad idea for EMBY to fallback to aac 2.0 (stereo) in this situation? e.g. "Converting audio stream due to invalid audio channel layout" and then transcoding/downmixing the invalid aac 5.1 to aac 2.0? This is just an idea, of course I understand if you don't want EMBY to handle invalid video files ...

Thanks again!

Given that channel layout, the one described as "5.1 (side)" has a wrong name - it should be a form of 6.0, as it has no frequency-restricted channel.

It that's the case and ffmpeg can't even itself eat the output it is creating, then it's clearly a bug in ffmpeg.

If we would be doing this for all the invalid videos we get to see, it would probably bind all developers resources 24/7  

But besides economical insanity, I think this would be a very wrong path to follow. It is well-known that VLC is one of the (or probably THE)  most tolerant player(s). But what does that give? It causes video creation to be done less accurate, people think all must be right - because it plays. Then, users go to other players which are implementing things right and complain that such videos aren't playing - even though they do with VLC or Exoplayer. 
Now, think this further: if other vendors would be starting to be more tolerant as well, then their increased tolerance wouldn't be exactly equal to VLC and all others who might follow the same path. Eventually, this would end up in a situation where more and more videos are incorrectly encoded, and some videos would play here and others only there and you could no longer rely on being able to play regular videos on all available players. Making this possible is what specs and standards are made for and I think we can all be glad that those exist.

Sure, as I said, I totally get it.

I just wasn't sure if EMBY has some sort of media error correction built-in.

 

It's just a weird problem to have/debug, I've been using ffmpeg for years now and audio channel layout was never a problem until the update.

Again, thanks for your time!

I have the same AAC 5.1 play problem 。But the same file will be fine play in  4.7.12 server.(ffmpeg 5.0). By th way 4.0.56 automatic index on LastWatchedEpisodes(SeriesPresentationUniqueKey) select time is too long ,over 10s.

OK but one is windows and one is linux. That makes this comparison a bit of apples to oranges. What if you try the 4.8 release on windows?

I Only use 4.7.12 in windows for my server.  I use 4.8XX  in linux is ERROR above . But  I use 4.7.12 in linux . It is also OK !!!!

You're  not able to try 4.8 on windows?

[sapphire_z 0]

Yes Windows Server is not my own 。I Only Can get Log from it！

[Luke 37096]

@sapphire_zare you still having an issue with this?

[sapphire_z 0]

I stopped paying attention to the issue of playing AAC5.1 files later because I found other files to replace them. However, the previous AAC file playback was still not possible in versions after 4.8, and it was normal in version 4.7.12.

I just resolved the performance issue regarding continuing to watch a few days ago. The WSL+Docker Desktop must copy the library. db to the image drive like /root/, and cannot be placed in WSL /mnt/d and then mounted on the docker system. WSL conversion of disk IO will result in significant loss.
