I had a look at the projects page, and I believe that (as I just wrote
in a previous email), the first goal for the rtsp/rtp work should be to
cleanup the code and improve its quality (ensuring that the design is
consistent with the appropriate RFCs).
After this first step, I believe that there are some bugs to fix (RTCP
RR) and features to improve (better recovery after lost packets, handling
of packets arriving in the wrong order, etc...)
Only after this it will be possible to start adding new features.

If there is an agreement on what I wrote above, I can volunteer as a mentor

I think a nice qualification task can be to get the H.263 depacketisation
patch that has been recently posted and improve it so that it can be
included in svn (not sure if this is too simple - an almost working patch
already exists - but being able to receive H.263 over RTP seems to be a
feature that many people want in svn).
