use two fifos (see mkfifo: "mkfifo fifo1 fifo2") and -vo yuv4mpeg:file=fifo1.
Make your filter create the same format as output (should be trivial) and read from
fifo1 and write into fifo2.
Then last start mencoder fifo2 (or for testing just use mplayer on
fifo2, if you can get mplayer to play it, making mencoder encode it is
not hard).
You will have to find some other way to deal with audio though.
