I found on my P4 2.2Ghz (celeron) that it could only transcode from
MPEG2 (this sample was 544x576 ~2.5mbit/s) to xvidavi at 9fps - nasty
for live broadcast.

It also seems that the libmpeg2 decoder that supports the extra xvid
outputs and YUV, writes to a file.

How does one go about transcoding the entire video and audio into a
hinted mp4 file to then stream to (for example) the darwin streamign
media?  Mp4live wants a video for linux card, and I don't see anything
else for live streaming :-(

Andy.
