../sys/decklink/gstdecklinkvideosink.cpp:1006:11: error: ‘GstDecklinkVideoSink {aka struct _GstDecklinkVideoSink}’ has no member named ‘scheduled_stop_time’

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.

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).

Direct applying the commit 7bb6443. This could fix also unexpected
nal dropping when nonzero "config-interval" is set.
(e.g., gst-launch-1.0 videotestsrc ! x265enc key-int-max=30 !
h265parse config-interval=30 ! avdec_h265 ! videoconvert ! autovideosink)
Similar to the h264parse, have_{vps,sps,pps} variables will be used
for deciding on when to submit updated caps or not, and rather mean
"have new SPS/PPS to be submitted?"

This is now handled directly in gstaudiosrc/sink, and we were setting
it in the wrong thread anyway. prepare() is not the same thread as
sink_write() or src_read().
We now have options for all plugins, so we will just disable these in
the cerbero recipe instead. These require external deps, so they won't
affect gst-build either.
When the position query fails the returned value shall remain -1 instead of 0 to
avoid confusion on application side between error and beginning of media.

Although RTMP_ConnectStream() was failed, librtmp's internal memory
is not freed by RTMP_ConnectStream(), so RTMP_Close() should be called
before RTMP_Free()

This adds "restore-crtc" property using which one
can restore previous crtc mode.
By default it is enabled, if CRTC was already
active with a valid mode and kmssink set a new mode
on CRTC using force-modesetting.
This helps user restore previous crtc mode and get
the previous session back after running a kmssink
pipeline involving a force-modesetting.
For e.g. When running a kmssink pipeline on rpi
using force-modesetting on tty console, it was giving
a blank screen after pipeline, and now with help of restore-crtc
functionality, CRTC is set with previous crtc mode
previously active on tty console.

This allow setting properties that contains spaces. The spaces are
replaced with '-'. As an example, one can set the connector proper
"scaling mode" with the following:
... ! kmssink connector-properties="s,scaling-mode=1"

Can be used to pass custom connector properties to DRM. Properties can
be enumerated using modetest tool. These properties can then be applied
with the following gst-launch-1.0 syntax. Note that the name of the
structure is ignored.
... ! kmssink connector-properties="s,props1=value,props2=value"

drmModeGetFB returns -EINVAL for multi-planar framebuffers. Instead of
depending on the framebuffer dimensions to select the mode, use width
and height from GstVideoInfo, which was used to create the framebuffer
in the first place. This enables kmssink to display multi-planar
formats such as I420 or NV12 with modesetting enabled.

Since both audio and video capture devices declare the KSCATEGORY_CAPTURE interface,
plugging a camera that supports both could result in an audio device being mistaken
for a video one.

If we drain after a discont, the discont time given by the stream
synchronizer is already the time after the discontinuity. But we need to
drain all pending data based on the previous discont time instead.
