So you can report to the driver dev, the selected pitches and offsets are
passed back to the driver. So you should never see bad rendering as the driver
is supposed to validate and then it may pick a slow path or fail. Bad rendering
is not a GStreamer bug here.

It's nice feature though to try and match the driver pitch.
