[Live-devel] Multicast addresses for MPEG4 and H.264 streams

[Piers Hawksley]

Can live555 stream H.264 or MPEG4 video to rtp://<multicast addr>:1234 
without using RTSP to set-up the stream (e.g. the client might be on a 
different subnet to the live555 server) ?

I am extending a program (a camera application running on Embedded Linux 
and using live555 to serve the video streams) to add multicast streams. 
Using rtsp://user:pass@<camera addr>:8554/streamname in VLC I can view 
each multicast stream. Using rtp://<multicast addr>:<rtp port> I cannot 
view a stream (even if another instance of VLC has already started that 
stream on the same client PC). Is the password authentication causing a 
problem ?

When I connect using RTSP each stream's ServerMediaSession reference 
count (from sms->referenceCount(), where sms was created with 
ServerMediaSession *sms = ServerMediaSession::createNew(...) ) 
increments with each new multicast connection. Is this a count of the 
number of clients connected to the multicast stream ?
