Yes, VLC first requests regular RTP/RTCP-over-UDP streaming, but then - if it receives no data within a certain period of time - tries again, this time requesting RTP/RTCP-over-TCP streaming.

Yes, there should be - it’s done in the “OnDemandServerMediaSubsession” code, when the server handles the RTSP “PLAY” command.

Unfortunately, I can’t figure out why it’s not working for you.  You’re going to have to work through the “StreamReplica” code, checking that "StreamReplica::doGetNextFrame()” gets called, as it should.
