That's incorrect.  The RTSP specification (RFC 2326, section 10.12) defines 
an option for streaming RTP (and RTCP) packets over the RTSP (TCP) 
connection.  It is useful for streaming over a firewall that does not allow 
UDP packets to pass through.

RTP-over-RTSP is implemented (as an option) by the "LIVE.COM Streaming 
Media" libraries, which VLC uses to implement RTSP *client* support.  The 
"--rtsp-tcp" command-line option enables this.

Unfortunately VLC does not yet use the LIVE.COM libraries to implement RTSP 
*server* support, and the existing RTSP server implementation in VLC 
apparently does not support RTP-over-RTSP.

         Ross.
