[mythtv] Mythmusic and corrupt FLAC files

Sun Dec 26 22:26:00 UTC 2004

Hmmm... checked some of my "corrupt" files... the metaflac stuff shows 
proper data, no problem.

The files will play on vlc (a Mac/Linux multimedia player) and mplayer 
seems to "play" them (at least it doesn't error... I'm not set up to 
run it through speakers right now).

flac command line errors with 
FLAC__STREAM_DECODER_ERROR_STATUS_LOST_SYNC unless a "-F" is given to 
skip the errors... if you do that, it seems to play them fine.

I also tried upgrading from flac-1.1.0 to flac-1.1.1 and didn't see a 
difference.

On in the search.
