Remove the method's unused parameter.
Remove the GStreamer 0.10.22 run-time validation, since we are using
GStreamer 1.0 officially.
Remove the creation of a spurious Bin for the video sink, since
either the fpssink or the webkitsink are valid sink elements.
Change fpsink to a GRefPtr.

Now, createVideoSink() returns a simple pointer to the created sink
element.
