Sure. I'll only report problems that can be reproduced by the test
programs which are not modified. And this is the case.

Now the question is why the RTSP server always tries to output
multicast stream. Looking at the code in
PassiveServerMediaSubsession.getStreamParameters(), the stream type is
hardcoded as multicast by the line "isMulticast = True;". Is it
intended or it's a bug?
This problem can be workarounded by setting "isMulticast = False;" in
