I wish smebody who knows more about it would comment, but I
*think* that the stream.yuv file is a fifo, so you can just
call mencoder right after you start mplayer and avoid creating
a 15G file. I don't think a fifo can get that big anyway...
somebody with experience doing this needs to speak up here.
