Yes, you must also update the "MediaSession::initiate()" function (in 
"liveMedia/MediaSession.cpp" in the LIVE.COM code) to handle the 
"video/H264" MIME type.  Search for "MP4V-ES" to see how this is done for 
(regular) MPEG-4 video.  You will need to add a similar "if" branch for "H264".

Once you have this working, it would be great if you would post the code 
for your "H264VideoRTPSource" to the "live-devel" mailing list, so I can 
include it in a future release.
