This filter, when used in the "pad" mode, currently makes the
distinction between limited and full range solely by testing for YUVJ
pixel formats at link setup time. This is deprecated and should be
improved to perform the detection based on the per-frame metadata.
In order to make this distinction based on color range metadata, which
is only known at the time of filtering frames, for simplicity, we simply
allocate two copies of the "black" frame - one for limited range and the
other for full range metadata. This could be done more dynamically (e.g.
as-needed or simply by blitting the appropriate pixel value directly),
but this change is relatively simple and preserves the structure of the
existing code.
This commit actually fixes a bug in FATE - the new output is correct for
the first time. The previous md5 ref was of a frame that incorrectly
combined full-range pixel data with limited-range black fields. The
corresponding result has been updated.

range by testing for the deprecated YUVJ pixel formats at link setup

based on the per-frame metadata.
Rewrite it to calculate the black pixel threshold at the time of
filtering a frame, when metadata about the frame's color range is known.
Doing it this way has the small side benefit of being able to handle
streams with variable metadata, and is not a meaningful performance
cost.

Bugfix: The OpenVino DNN backend in the 'async' mode sets
'task->inference_done' to 'complete' prior to data copy from
OpenVino output buffer to task's output frame.
This order causes task destroy in ff_dnn_get_result_common()
prior to model output processing.

PI, PHI and E are defined in libavutil/eval.c, and user may use these
constants for scale_qsv filter, so we needn't re-define these variables
in vf_scale_qsv.c

When process yuv420 frames, FFmpeg uses same alignment on Y/U/V
planes. VPL and MSDK use Y plane's pitch / 2 as U/V planes's
pitch, which makes U/V planes 16-bytes aligned. We need to set
a separate alignment to meet runtime's behaviour.
Now alignment is changed to 16 so that the linesizes of U/V planes
meet the requirment of VPL/MSDK. Add get_buffer.video callback to
qsv filters to change the default get_buffer behaviour.
Now the commandline works fine:
ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 3082x1884 \
-i ./3082x1884.yuv -vf 'vpp_qsv=w=2466:h=1508' -f rawvideo \
-pix_fmt yuv420p 2466_1508.yuv

VPP in the SDK requires the frame rate to be set to a valid value,
otherwise init will fail, so always set a default framerate when the
input link doesn't have a valid framerate.

It means more than one output is ready when
MFXVideoVPP_RunFrameVPPAsync() returns MFX_ERR_MORE_SURFACE [1].
Currently the returned value from MFXVideoVPP_RunFrameVPPAsync() might
be overridden, so the check of 'ret == MFX_ERR_MORE_SURFACE' is always
false when MFX_ERR_MORE_SURFACE is returned from
MFXVideoVPP_RunFrameVPPAsync()
