Issue with mythvideo and mkv files with subtitles when passing ac3 audio through

Reported by: mythtv@… Owned by: greg
Priority: minor Milestone: 0.21.1
Component: mythvideo Version: 0.21-fixes
Severity: medium Keywords: mythvideo mkv ac3
Cc: mythtv@… Ticket locked: no

Description

My setup:

AudioOutputDevice? ALSA:hw:0,0 PassThruOutputDevice? ALSA:hw:0,0 UseVideoTimebase? 0 AC3PassThru 1 AggressiveSoundcardBuffer? 0

When playing a 720p mkv video with subtitles included, the audio does not work properly (ie - about 1/2s of audio plays for every 5-10s of video), but video is perfectly smooth. I get the following in the logs:

2008-04-23 23:48:08.422 NVP: 1200 progressive frames seen. 'video_output' mean = '41706.59', std. dev. = '50.46', fps = '23.98' 2008-04-23 23:48:09.506 AFD: No codec for stream index 3, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:10.507 AFD: No codec for stream index 3, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:10.507 AFD: No codec for stream index 2, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:10.591 AFD: No codec for stream index 4, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:10.591 AFD: No codec for stream index 5, type(Subtitle) id(Unknown Codec ID:94210) 'video_output' mean = '41706.59', std. dev. = '51.63', fps = '23.98' 2008-04-23 23:48:16.054 AFD: No codec for stream index 2, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:16.055 AFD: No codec for stream index 4, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:16.221 AFD: No codec for stream index 3, type(Subtitle) id(Unknown Codec ID:94210) 2008-04-23 23:48:16.221 AFD: No codec for stream index 5, type(Subtitle) id(Unknown Codec ID:94210)

MKV's without subtitles work just fine.

Curious -- any updates on this? Is there anything I can do to help?

I have tried several times to reproduce this and so far I cannot. I've tried with the latest -fixes and trunk pre and post the recent ffmpeg sync the other day.

Are you still having this problem? Can you try updating your copy of -fixes? Or provide me a small sample that shows the behaviour?

I'll get a current build of -fixes and try it out, and will let you know.

Thanks!

[Sorry it took so long to test, sigh!]

It does appear to be working with the newest -fixes. Please close, and thanks!
