Seconded. This is a designchoice in the RTSP protocol. Everything is
possible, but you are never guaranteed that anything should or will
work. In hindsight it is one of the biggest problems with the entire
RTSP protocol. Extensions to the protocol to query this information
have been made, but are largely unsupported. RTSP 2.0 does solve this,
but hardly anything supports RTSP 2.0 yet.
