--- Comment #1 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
We could just ignore NULL frames, but why would we get NULL frames at all?

Also we can't really do anything with the audio in those cases either, because
we need to get the hardware reference clock time at the time of capture...
which we can only get from the video frame, not the audio packet.

Maybe we could send the audio with GST_CLOCK_TIME_NONE and then interpolate. If
you just ignore the audio when a NULL video frame is arrived, do you get
dropouts in the audio?
