async=false on the sink should have no effect on any other elements and
especially not on setting caps anywhere. However you will need to do
more than that to properly integrate your hardware pre-rolling into
GStreamer. Check the code in GstBaseSink to see what it is doing for
pre-rolling. You'll need to do that just with your hardware pre-rolling.
I think it will also be a good idea to extend basesink a bit to allow
easier integration of more special pre-rolling mechanisms. I.e. allow
the subclass to get some control over what is happening there and when
the sink is considered pre-rolled and when not.
