I have cook working too now, I think it's starting to look interesting at
this point. I should still get the initial_pause and udp/tcp selection
fixed, but that can't be all too big. At that point, I'll need input on
bitrate selection and would like help with relicensing or rewriting of the
checksum calculation code from librtsp. Has anyone looked at my patches yet?
I've got newest versions of all 5 attached.

- memleak-fix fixes a memleak in rtsp.c (this should be applied regardless)
- flags-field adds a flags field to the parse_packet functions, which real
needs
- protocol-declaration adds support for x-pn-tng/protocol in addition to
rtp/avp/protocol
- rmdec-split-functions splits functions in rmdec.c and exports relevant
parts for use in rtp_rm.c (next patch)
- realmedia adds rdt support to rtsp.c/rtp.c and implements most specific
stuff in rtp_rm.c (new file)
