Source is 720p, encode it to 480p with subtitles - FIFO is produced at
/tmp (TMPFS filesystem at my box)

mkfifo /tmp/video.source
mplayer source.mp4 -noconfig all -vf-clr -nosound -benchmark -ass -sub
subtitle.ass -vf scale=854:-3 -vo yuv4mpeg:file=/tmp/video.source
&>/dev/null &
ffmpeg -i /tmp/video.source -vcodec mpeg4 -b 800k -y test.avi
ffmpeg -i test.avi -i source.mp4 -acodec copy -vcodec copy -y
test-out.avi -map 0:0 -map 1:1
rm -f /tmp/video.source

Personally, i'm using x264 and MP4Box/mkvmuxer instead.
