The filter supports two inputs and (implicitly) scaling the second input
during composition, unlike the software overlay.
The code has been separated into common interface and qsv overlay
implementation. The common part mainly creates the qsv session and
manages the surface which is nearly the same for all qsv filters.
So the qsvvpp.c/qsvvpp.h API can be used by other QSV vpp filters
to reduce code redundancy.
Usage:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=eof_action=repeat:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M
-c:v h264_qsv -y out.h264
Two inputs should have different sizes otherwise one will be completely
covered or you need to scale the second input as follows:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=w=720:h=576:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M -c:v
h264_qsv -y out.h264

Add common filters of the qsv vpp features including scale,denosie,
deinterlace,frc,crop and procAmp.
Performance will be significantly reduced in the test if using cascade
mode just like qsv framerate + qsv scale + qsv deinterlace + qsv denoise in
separated way no matter in system or video memmory cases.
And the code is so redundant because so much the same just as session and
surface's creation and management.
So we add a common qsv filter.
Usage:
-hwaccel qsv -c:v h264_qsv -r 25 -i in -vf
vpp_qsv=w=iw/2:h=400:deinterlace=1:framerate=60:detail=50:denoise=50
-b 2M -maxrate 3M -c:v h264_qsv -y out.h264

This one changes the previous vmaf patch to libvmaf to keep it separate from the
native implementation of vmaf inside ffmpeg later.
