According to a CNet page I found:
http://reviews.cnet.com/4520-10163_7-6279061-6.html

./mencoder -ovc raw -ofps 15 -nosound -vf \
scale=160:-2,expand=160:128,format=bgr24 YourVideoNameHere -o movie.avi

./2bppconv movie.avi FinalMovieName.avi

I'm not sure why they have "nosound" in there.  Maybe replace that
with "-oac faac"?  And I don't know what the 2bppconv does.

Here's a mencoder mailing list thread:

Here's a thread on encoding H.264 with ffmpeg:
