I tried ffmpeg -i a.mp3 -i b.mp3 -filter_complex concat=n=2:v=0:a=1 c.mp3 c.ogg
but c.mp3 is the concatenated result while c.ogg is a converted copy of a.mp3 I've tried a bunch of other possibilities, including using asplit, but I just end up with less than helpful error messages. I've read much of the extensive ffmpeg documentation, including the filter document, but I don't think I understand how one connects the various streams that can be created. Even an explanation of why the above command does what it does would be helpful. -- View this message in context: http://ffmpeg-users.933282.n4.nabble.com/How-do-I-concatenate-audio-files-and-produce-two-copies-in-different-formats-tp4672781.html Sent from the FFmpeg-users mailing list archive at Nabble.com. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
