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. Running ffmpeg2theora --help reports that
ffmpeg2theora accepts a range of -2 to 10 for the --audioquality
option and a bitrate of 32 to 500 for the --audiobitrate option, but
it doesn't appear to actually accept any of the low end numbers.
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?

Dvgrab command
Recently I tried to live broadcast the video of our workshop. but i was
failed.
I applied the following command
dvgrab --format raw - | ffmpeg2theora -f dv -x 80 -y 64 -o /dev/stdout - |
oggfwd myvps 8000 hackme /live.ogg
I was able to configure video size but unable to configure audio bitrate.
it was taking 60 kbps for audio and 20 kbps for video.
I want 20 kbps for audio...

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
