           Summary: GstDiscoverer: signals "discovered" and "finished" are
                    only emitted in async mode
    Classification: Platform

By looking at the code, GstDiscoverer only emits the signals "discovered" and
"finished" in async mode. "started" on the other hand is emitted in both modes.

The fact that there is currently no mention of this behaviour in the
documentation makes it confusing. Personally I think it should be all or
nothing; all signals in both modes or non in blocking mode.

At least describe the intended behaviour in the documentation.
