ffmpeg

 
Dreamhost supports ffmpeg

It appears SVN FFmpeg does not support many formats including mp4,3GP and rm because of which video sharing scripts use mencoder to support all video formats.

The command I use is:

/usr/local/bin/mencoder "video.mp4" -o "video.flv" -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=800:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup
