What the world needs is a media recipe wiki. But I'd try again with ffmpeg. It has the most active development and user group. The helpful users make up for the lousy docs. 1. Do you have a very recent version of ffmpeg? I'd urge you to use svn, but at least 0.5.1. 2. ffmpeg -i source.mkv -vcodec copy -acodec copy output.avi , should work if source mkv is in mpeg-4 and mp3. 3. If not, run ffmpeg -i source.mkv and post to the ffmpeg user list. Good luck. sean -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
