The Vorbis encoder could not set up a mode according to the requested quality or bitrate.
I built ffmpeg2theora from SVN, using libogg 1.1.4, libvorbis 1.2.3 and Thusnelda from SVN.

It appears that the lowest acceptable value for --audioquality is -1 and the lowest acceptable value for --audiobitrate is 45. Anyone know what's up? jason$ ffmpeg2theora --audioquality -2 /Users/jason/tes...

A/V sync strategies
I tried to encode some video from a DVD with encoder_example and ffmpeg2theora, and it looked great, except that with both encoders the A/V sync would drift noticeably after about 10 minutes, and by the end of a two hour movie it would be a couple seconds off. So instead of just whining about this and waiting for someone else to fix it, I decided to try to learn about what's causing the
