85ef4166a2 decklinkvideosrc: Issue "no signal" warnings
When a frame is found to not have an associated input source (cable
unplugged, wrong mode selected), an element warning will be issued. When
the next frame in the stream is found to have an input source selected
(e.g. cable replugged), an element info will be issued.

ac37bdb9ac decklink: Use gst_clock_adjust_with_calibration() and unadjust_with_calibration()
Instead of hand-crafted versions of the same calculation. These
calculations are still too complicated though.

d8327b397d decklink: Require a clock when going from PAUSED_TO_PLAYING and don't crash if there is none
Also when going from PLAYING_TO_PAUSED, the clock might've been unset in the
meantime, e.g. because the element was removed from its surrounding bin.

8faa36e105 decklinkvideosrc: Add support for GstVideoTimeCode
The timecode will be fetched from the decklink source and attached to the
video buffer.

41283361fa decklinkvideosrc: Fix previous commit
The frames queue might return nothing (be empty) if we're flushing.

Move the assertion to after the flushing check

9764e22a5c decklink: Add a clock epoch that is used as offset whenever restarting the clock
Otherwise we're going to return times starting at 0 again after shutting down
an element for a specific input/output and then using it again later.

cf66541850 decklinkvideosrc: fix mode autodetection
The autodetection mode was broken because a race condition in the input mode
setting. The mode could be reverted back when it was replaced in
the streaming thread by the old mode in the middle of mode changed callback.

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.

9ed4054a94 decklinkvideosrc: Apply the diff between element and pipeline "base" time in all cases
Even if both clocks have the same rate, we need to apply this diff. Only when
it's the same clock we don't, as it's our clock then.

f83ac624e3 decklinkvideosrc: Add the diff between the pipeline base time and when we start to play
Add the diff between the external time when we went to playing and
the external time when the pipeline went to playing. Otherwise we
will always start outputting from 0 instead of the current running
time.

e8167dd118 decklinkvideo{src,sink}: Sample the internal clock immediately after starting the device
Otherwise we might stay at 0.0s for too long because we will take the first
timestamp we ever see as 0.0... which will be after we started the device.

22b0a4dad5 decklink{audio,video}src: Take the capture times from the pipeline clock
Not from the decklink clock. Both will return exactly the same time once the
decklink clock got slaved to the pipeline clock and received the first
observation, but until then it will return bogus values. But as both return
exactly the same values, we can as well use the pipeline clock directly.

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.

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.

4531a341a8 decklinkvideosrc: Post LATENCY message when the mode changes
Different modes have different framerates, and thus different latencies. We
might need to reconfigure the latency of the pipeline.
