I'm not sure if it's what the OP meant, but Axis has a very strange idea 
of what "multicast" means.

Instead of just sending packets out blindly for anyone to receive who 
wants, letting the switching fabric take care of pruning off network 
segments where no one wants to listen, Axis makes the first client send 
an RTSP request to start the stream.  Then, instead of some interleaved 
A/V format, you get audio and video elementaries on different ports.

I guess this allows a client to negotiate certain parameters of the 
stream, but how is that helpful in a multicast scenario, where 
presumably you have later clients who will just come along and "listen 
in" on the stream?  If they're expected to know /a priori/ what format 
the A/V stream is in, why allow the first client to negotiate anything?

Too much brännvin consumption going on there, I think.
