Hi all,

Thanks for the feedback :)

Like this:

     mkfifo fifo.ppm
     pd -lib gridflow -open cycletile1.pd &
     cat fifo.ppm |
     ppmtoy4m -S 420mpeg2 -F 25:1 |
     mpeg2enc -f 8 -a 2 -o video.m2v

The Pd patch writes success frames in uncompressed PPM format into a 
unix FIFO (named pipe), which is sent to mpeg2enc (as above).  The patch 
also writes audio in WAV format, which I then trimmed in Audacity to be 
the same length as the video, and encoded/multiplexed like this:

     twolame -b 224 audio.wav audio.m2a
     mplex -f 8 -V -o final.mpeg video.m2v audio.m2a

Hope that helps,


Claude
