[Live-devel] h264 streaming using rtp/rtsp

This depends on how the file was 'hinted'.  (Darwin Streaming Server 
doesn't know anything about the contents/format of the files that it 
streams; it just transmits RTP packets using the file's 'hint track'.)  But 
if the file was 'hinted' correctly, then Darwin will be streaming the 
H.264/RTP data in the standard, IETF-compliant way, and VLC will need only 
an updated "LIVE.COM Streaming Media" library - containing a new 
"H264VideoRTPSource" class - in order to play it.

No.  A "H264VideoRTPSink" class - being LIVE.COM code - is necessary only 
for streaming from a LIVE.COM server.
