This is a known problem, the native Ogg demuxer does not provide the FFmpeg decoder the extradata in the right format IIRC. It should work fine if you add '-demuxer lavf' to the command line and use the libavformat Ogg demuxer instead. There is no real (short-term) fix for this, both demuxers have a different set of strengths and weaknesses... Diego -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
