But wouldn't GstDiscoverer open the connection to the specified URI, try to
detect, and then close?
i.e. after using GstDiscoverer a second connection would still be necessary
to actually fetch the data.

Isn't it possible to detect the type "on the fly" using typefind? Assuming
that we know that it is always a RTSP stream.
