Yes. By default, a RTSP server will support RTP-over-UDP, and
RTP-over-RTSP(TCP). However, if you call
setUpTunnelingOverHTTP()
(with a non-zero port number) on your “RTSPServer” object - as is done in the
“testOnDemandRTSPServer” and “live555MediaServer” applications - then it will
also support RTP-over-HTTP(TCP) .
Also, if you call
disableStreamingRTPOverTCP()
on your “RTSPServer” object, it will not support RTP-over-RTSP(TCP) streams,
nor RTP-over-HTTP(TCP) streams. I.e., it will support RTP-over-UDP only.
In summary, if you want to support only RTP-over-UDP, then call
disableStreamingRTPOverTCP()
(Note that there is no way to tell your server that to accept *only*
RTP-over-TCP (RTSP or HTTP). Nor will there ever be; RTP-over-TCP is
generally discouraged.)

I’m not sure I understand this question - but we currently support
RTP-over-HTTP in both our client and our server implementation. However, we
currently do not support RTP-over-HTTPS (for either our client or server),
although it’s likely that we will support this sometime in the future.
