That pipe should be a semicolon instead, IMO.

I don't think mplayer can multiplex audio and video. My guess would be:

> mkfifo stream.yuv; mkfifo stream.pcm
> mplayer -ass -aub subtitle.ass -vo yuv4mpeg -ao pcm:file=stream.pcm file.avi
> mencoder stream.yuv -audiofile stream.pcm <options> -o fileout.avi

Totally untested. I don't know about sync issues though, but this might
be worth a try.

You could also use mplayer's "-dumpaudio -dumpfile stream.pcm" and get
the original encoded audio, and reuse it in mencoder with "-oac copy".

Just my 0.02$,
