MPlayer can already be used as a RTSP client (see
<http://www.live.com/mplayer/>), and adapting it to act as a *receive-only*
SIP client would be relatively straightforward, because SIP is quite
similar to RTSP (and the LIVE.COM Streaming Media libraries already include
some basic SIP client functionality). H.323 would be more work (because
it's quite different from RTSP and SIP), but H.323 seems to be pretty much
a dead end; all of the momentum in the IP conferencing/telephony world
these days seems to be with SIP.
The more difficult task, though, would be to make MPlayer act as a
*two-way* SIP audio/video conferencing tool - i.e., with the capability of
sending data as well as receiving it. This would presumably require
hooking together MPlayer and MEncoder functionality into a single
application (with SIP/RTP sending/receiving support). That would seem to
be the non-trivial task...
