This is only loosely tested.  It might not work at all, but I think it
does.  (At least the resulting file size was a multiple of
width*height*3 and looked RGB24ish.)

mencoder movie.avi -ac none -ovc raw -vf format=rgb24 -of rawvideo -o fifo

You can add any filters you need to the filter chain and it should Just
Work (if you want to any image processing before handing it off to your
app that reads from the fifo).  If you want a different format than
RGB24, you can just specify a different fourcc value.

Cheers,
Jason.
