Unknown audio code 1330664787 in youtube-dl mkv files

[Tom Dexter <digitalaudiorock@…>]

Most mkv format videos I download from youtube using youtube-dl have no audio in mythtv, and the playback log shows:

2016-09-25 09:12:52.410511 E [16583/16666] Decoder avformatdecoder.cpp:5043 (GetFrame?) - AFD: No codec for stream index 1, type(Audio) id(Unknown Codec ID:1330664787)

Other players like xine seem to have no problem with it. I wasn't sure whether to of not to log this as FFMPEG, but close that as I'd guess that's likely the issue (possibly a required version bump).

I believe that codec id may be opus. Since you posted as a 0.27.6 issue, while I have no idea if it makes any difference, have you tested on 0.28? 0.28 got a FFmpeg bump along the way, and I believe it supports opus.

[Tom Dexter <digitalaudiorock@…>]

I'm not in a position to test 0.28 at the moment, but I think you're almost surely correct. I just verified (using mplayer -identify) that the audio in these is in fact opus. I'm running under Gentoo and the other players, like xine, that can play these are using ffmpeg-2.8.6, and I see that mythtv 0.28 is using ffmpeg 3.

Given that, I'm all but sure 0.28 will handle these, so this can probably be closed.

Thanks!

[Tom Dexter <digitalaudiorock@…>]

Just to confirm: I've updated to 0.28 today and these do play no problem...so this can be closed. Thanks!

I use the Firefox plugin "Easy Youtube Video Downloader Express" and I have never had a problem - the videos download as mp4 files with AAC audio.

I am closing this ticket as fixed, since it is fixed in 0.28.
