9f1fbd3649 decklink: Fix crash when probing without driver
If there is no decklink hardware/driver, the devices list is empty (NULL), so
this needs to be checked before iterating over the list.

82e23a27f7 decklinkaudiosink: Drop late buffers
Asking decklink to render audio data seems to be based entirely on
the sample counts which completely disregards the timestamps
we pass to decklink.  As a result, we need to explicitly check
for late buffers and drop them ourselves.

99af098a7b decklinkvideosrc: Retrieve mode of the ancillary data from the frame
Instead of using the information we stored ourselves for the video frame
itself. Which was also the wrong one: it was the mode from the property,
not the autodetected one.

ab8bd0aa44 decklinkaudiosrc/decklinkvideosrc: Do nothing in BaseSrc::negotiate() and always set caps in ::create()
We don't support negotiation with downstream but simply set caps based
on the buffers we receive. This prevents renegotiation to other formats,
and negotiation to NTSC in mode=auto in the beginning until the first
buffer is received.

As side-effect of this, also remove various other caps handling code
that was working around the behaviour of the default
BaseSrc::negotiate().

bf9ecd65cf decklinkvideosrc: Don't report that we have signal until we know for sure
Previously we would've reported that there is signal unless we know for
sure that we don't have signal. For example signal would've been
reported before the device is even opened.

Now keep track whether the signal state is unknown or not and report no
signal if we don't know yet. As before, only send an INFO message about
signal recovery if we actually had a signal loss before.

line21dec element, and have to perform fewer transformations in the
decklink elements (which were also buggy as they assumed a single byte
triplet per meta).

59c5ae2817 decklink: calculate the decklink output time from the internal clock
Fixes the time calculations when dealing with a slaved clock (as
will occur with more than one decklink video sink), when performing
flushing seeks causing stalls in the output timeline, pausing.

Tighten up the calculations by relying solely on the internal time
(from the internal clock) for determining when to schedule display
frames instead attempting to track pause lengths from the external
clock and converting to internal time.  This results in a much easier
offset calculation for choosing the output time and ensures that the
clock is always advancing when we need it to.

This is fixup to the 'monotonically increasing output timestamps' goal

1a360a1c65 decklinkvideosrc: respect pixel format property even if mode is set to auto
Before this patch, if mode=auto and video-format!=auto, video-format would
always be ignored, and get set to 8bit-yuv, or if detected to be RGB444, then
it would be set to 8bit-argb. This change respects video-format if it is set
to 10bit-yuv (v210) or 8bit-bgra, even when mode=auto.

Closes #772

946cbbccc1 decklink: wait for stop with a timeout
Decklink sometimes does not notify us through the callback that it has
stopped scheduled playback either because it was uncleanly shutdown
without an explicit stop or for unknown other reasons.

Wait on the cond for a short amount of time before checking if scheduled
playback has stopped without notification.

bf849e9a69 decklink: start scheduled playback in paused
This is part of a much larger goal to always keep the frames we schedule to
decklink be always increasing.  This also allows us to avoid using both the
sync and async frame display functions which aren't recomended to be used
together.

If the output timestatmsp is not always increasing decklink seems to hold
onto the latest frame and may cause a flash in the output if the played
sequence has a framerate less than the video output.

Scenario is play for N seconds, pause, flushing seek to some other position,
play again.  Each of the play sequences would normally start at 0 with
the decklink time.  As a result, the latest frame from the previous sequence
is kept alive waiting for it's timestamp to pass before either dropping
(if a subsequent frame in the new sequence overrides it) or displayed
causing the out of place frame to be displayed.

This is also supported by the debug logs from the decklink video sink
element where a ScheduledFrameCompleted() callback would not occur for
the frame until the above had happened.

It was timing related as to whether the frame was displayed based
on the decklink refresh cycle (which seems to be 16ms here),
when the frame was scheduled by the sink and the difference between
the 'time since vblank' of the two play requests (and thus start times
of scheduled playback).
