I might be talking complete nonsense here but I believe the server is
using the code in modules/misc/rtsp.c and it barfs because your SETUP
request does not contain a "client_port" field.

Rather than using --rtsp-host on the command-line, try using --sout
'#rtp{sdp=rtsp://192.168.11.18:554}' and it should then use the code in
modules/stream_out/rtsp.c and things might improve. They did for me.

If some VLC guru wants to explain the difference between --rtsp-host
and #rtp and why there seems to be 2 implementations of an RTSP server
in VLC, we'll be most grateful.

Cheers,
Eric.
