I have used the following the command with just ffmpeg to convert 
several different types of input videos to a Flash video. I've found 
that the audio bitrates are constrained, ie. some combinations work, 
others don't. The same is true for the video with respect to size and 
bitrate.

The resulting SWF plays find in browser based Flash players. You will 
need to embed the player appropriately in the HTML page with the size 
set in the <embed> tags in order to have the video display at the same 
size as it was encoded.

ffmpeg -y -i foo.mpg -t 600 -r 15 -s 320x240 -b 150 -ar 22050 -ab 32 foo.swf
