b2149e7bb4 decklinkvideosink: less-than-zero comparison of an unsigned value is never true
Use the correct type, GstClockTimeDiff, instead.

b6498c32f3 decklinkvideosink: Handle pipelines where the running time does not start around 0 properly
We were converting all times to our internal running times, that is the time
the sink itself spent in PLAYING already. But forgot to do that for the
running time calculated from the buffer timestamps. As such, all buffers were
scheduled much later if the pipeline's running time did not start at 0.

This happens for example if a base time is explicitly set on the pipeline.

a6744a915b decklinkvideosink: Consider pipeline latency, render delay and ts offset when scheduling frames
Without this, we will schedule all frames too late in live pipelines.

e3aaff400a decklinkvideosink: Remove late frame-dropping workaround for basesink bug
This was fixed by https://bugzilla.gnome.org/show_bug.cgi?id=749258
in basesink, and is not necessary to duplicate here anymore.

62f25894a5 decklinkvideosink: Don't require the same framerate in the input as the mode's framerate
We only really care about the timestamps for the sink.

4521524de3 decklink: Reset the clock calibration when unsetting the master clock
Otherwise the old calibration will stick around for the next time we use it,
potentially giving us completely wrong times.

4eb5cd9156 decklink{audio,video}sink: Only start scheduled playback once both sources are ready and we are in PLAYING
Otherwise we might start the scheduled playback before the audio or video streams are
actually enabled, and then error out later because they are enabled to late.

We enable the streams when getting the caps, which might be *after* we were
set to PLAYING state.

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.
