00176a1ddf decklink: Make sure our clock never returns NONE, always advances and does not jump when going from PAUSED to PLAYING
It basically behaves the same as the audio clocks.

8a5d2c561c decklinkvideo{sink,src}: Make elements more similar to the audio elements by enabling the video input/output only when getting the actual caps
This will also make it easier later to support caps changes and support
selecting the mode based on the caps if that should ever be implemented.

5a12b2670e decklinkvideosink: Stop scheduled playback shortly in PAUSED->PLAYING if it was running already
This fixes handling of flushing seeks, where we will get a PAUSED->PLAYING
state transition after the previous one without actually going to PAUSED
first.

92fa187d11 decklinkvideosink: Don't schedule too late frames in prepare()
Otherwise we will overflow the internal buffer of the hardware
with useless frames and run into an error. This is necessary until
this bug in basesink is fixed:

7b979703f8 decklinkvideosink: Keep track of the time when we went to PLAYING for the external clock too
Otherwise we're adding an offset of the time the pipeline was in PLAYING
already to the running time when converting it to our internal clock.

d2e309d341 decklinkvideosink: Get our own "start time" instead of the one of the pipeline
decklinkvideosink might be added later to the pipeline, or its state might
be handled separately from the pipeline. In which case the running time when
we (last) went into PLAYING state will be different from the pipeline's.

However we need our own start time to tell the Decklink API, which running
time should be displayed at the moment we go to PLAYING and start scheduled
rendering.
