Subject: [PATCH] lavf/vf_deinterlace_qsv: Enable the qsv deinterlace vpp
The current qsv deinterlace module does not work at all because MSDK needs user
to pass
extra parameters to enable hint functions,such as
denoise,deinterlace,composition and so on.
Usage:-hwaccel qsv -r 25 -c:v h264_qsv -i in -vf deinterlace_qsv=bob -b 2M
-maxrate 3M -c:v h264_qsv -y out.h264
