Actually the theora source comes with an demo encoder.  But since
the encoder understand only yuv4mpeg and wav, I have to use a
variant of the following script:

mkfifo -m 660 stream.yuv
mkfifo -m 660 stream.wav
mplayer -ao pcm -aofile stream.wav -vo null $1 &
mplayer -osdlevel 0 -vf eq2=1:1:-0.01:1,hqdn3d=4:3:6,noise=5uh \
  -vo yuv4mpeg -ao null -nosound $1 &
lt-encoder_example -v 7 -a 1 stream.wav stream.yuv > movie.ogm

So far I've not encountered any sync problems with my "scripted"
procedure. What would be nice with an mplayer "native" encode is
I can get the noise= filter to deblock the video properly.
