I am trying to convert an avi file (mpeg4 video, mp3 audio) to flac audio. Using "-lavcopts acodec=flac", I get an error message that the ouput buffer is too small, among other messages: -------------------------------------------------------------------------- [ken at Bugs root]$ mencoder /xfs/good/winners-p.avi -ovc copy -oac lavc -lavcopts acodec=flac -o /xfs/winners-flac.avi MEncoder SVN-r29701-4.4.1 (C) 2000-2009 MPlayer Team success: format: 0 data: 0x0 - 0x639b772a AVI file format detected.

I would also like to be able to capture directly to flac from my tuner card, instead of mp3, as I did for the file above. As always any and all help greatly appreciated. ken
