There are various issues to be addressed:
1) encapsulating h.263, mpeg4, or h.264 video in an RTP packet. As far 
as I remember, libavformat provides support for encapsulating mpeg4 
video in RTP packets, but it does not support h.26{3,4}. Enhancing 
libavformat for encapsulating such video in RTP should be fairly easy.

2) ensuring that ffserver can stream RTP from a live feed. It should 
work, but I never tried...

3) feeding a Darwin Streaming Server with the resulting stream. I do not 
know how to do this. If I remember well, live555 can probably feed a 
DSS, so the thing is at least documented...

I have 2) on my TODO list (but I am always short of time), and I will 
probably work on 1) in the future.
