I use MPlayer.
MPlayer's '-vo yuv4mpeg' will get you a YUV4MPEG2 stream - the header
isn't exactly correct sometimes but that's not hard to deal with (there
are suboptions to '-vo yuv4mpeg: to set the field order for example).
The most common thing that needs to be done is set the 'A' (sample
aspect) tag so that it's not "unknown" (0:):
YUV4MPEG2 W720 H576 F25000000:1000000 Ip A0:0
The output goes to 'stream.yuv' which can a fifo if desired.
ffmpeg can also be used to play divx movies and convert to "yuv".
Audio extraction and processing is left as an exercise for the reader
(mplayer -dumpaudio is one way).
There are other ways and tools but the ones above work well enough
that I haven't researched too many others.
Cheers,
Steven Schultz
