95eb492c32 Revert "decklinkvideosink: Scale down scheduled frame times to milliseconds" 
This reverts commit 3b7e0d7de3.

It was a bug in the driver and is supposed to be fixed with 10.8 and newer.

fafc8e564c decklinkvideosink: Made "auto" mode work according to caps 
When the mode of decklinkvideosink is set to "auto", the sink claims to
support the full set of caps that it can support for all modes. Then, every
time new caps are set, the sink will automatically find the correct mode for
these caps and set it.

Caveat: We have no way to know whether a specific mode will actually work for
your hardware. Therefore, if you try sending 4K video to a 1080 screen, it
will silently fail, we have no way to know that in advance. Manually setting
that mode at least gave the user a way to double-check what they are doing.

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.

4de7fdfa3a decklinkaudiosink: Throttle reading from the ringbuffer 
The driver has an internal buffer of unspecified and unconfigurable size, and
it will pull data from our ring buffer as fast as it can until that is full.
Unfortunately that means that we pull silence from the ringbuffer unless its
size is by conincidence larger than the driver's internal ringbuffer.

The good news is that it's not required to completely fill the buffer for
proper playback. So we now throttle reading from the ringbuffer whenever
the driver has buffered more than half of our ringbuffer size by waiting
on the clock for the amount of time until it has buffered less than that
again.

Otherwise we're going to starve other elements if the decklink clock

Of course this will still cause problems if the decklink clock and ours are
completely out of sync, or running at a very different rate. But this at least
works better now.
