I don't think using -ab is desirable. Plus it seems that -ab is ignored if -aq is set. Setting -aq 4 to a nominal 128kb/s achieves something similar to oggenc defaults. So for me this is a good compromise: ffmpeg -i somesong.mp3 -acodec libvorbis -aq 4 somesong.ogg The table here lists associated libvorbis quality levels and bit rates. http://en.wikipedia.org/wiki/Vorbis#Technical_details -aq4 128 kbit/s -aq5 160 kbit/s -aq6 192 kbit/s Bob
