Any method for checking if rtspsrc is actually connected?

[Chuck Crisler]

It seems surprising to me that you could have a successfully built pipeline
without pads on your source. I would think that it wouldn't link.

As far as detecting when the source is available, how about a thread that
sleeps for 1 sec (or so) then pings the server, terminating when a
connection is made so the pipeline can be built. That is basically what you
will need unless the server can announce that it is available somehow.
