    decklinkaudiosrc: Don't accept packets without timestamps after a discont

    We have no idea which timestamps they are supposed to have so the only
thing
    we can do at this point is to drop them. Packets without timestamps happen
if
    audio was captured but no corresponding video, which shouldn't happen under
    normal circumstances.

    decklinkaudiosrc: Don't crash when receiving video frames but no audio

    And mark these events as disconts to reset time tracking in the audio
source.

    decklinkvideosrc: don't crash if we get NULL video frames in the callback

    For some reason we seem to sometimes get NULL video_frames in the
    ::VideoInputFrameArrived() callback, observed on Intensity Pro cards.
