rtspsrc supports data transport over TCP and UDP and RTSP over tcp. I am
not aware of any player doing the RTSP requests over UDP nor is it clear
from the spec how this is supposed to work, or how a server should
support it. I don't know why that part is in the spec or what it means.
rtspsrc supportes rtspu:// protocols but interpretes it that the RTP
transport is only done over UDP unicast or multicast. VLC doesn't seem
to understand the rtspu protocol.
