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.
