<div><br></div>
<div>Yes, our RTSP server implementation supports multicast streams.
This is demonstrated in the various "test*Streamer" demo
applications. E.g., You can demonstrate this by uncommenting the
line</div>
<div>//#define IMPLEMENT_RTSP_SERVER 1</div>
<div>in "testProgs/testMPEG1or2VideoStreamer.cpp".</div>

<div><br>
Yes.<br>

does would it be able to handle having the client set the multicast IP

<div><br></div>
<div>No, because that is a silly idea. It's the role of the
server, not clients, to choose whether - and with what address/port -
a stream is multicast. See<font face="Lucida Grande" size="-4"
