To convert a video to the Flash Video format, use the mencoder command like this:

mencoder {SOURCE_VIDEO} -o {OUTPUT_VIDEO}.flv -of lavf -oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames

This assumes you have the lamemp3 libs installed and that the output video rate shoud be 500k (good for web content).

This works fine on Ubuntu 7.04 (and probably any other system with mencoder installed).
