Comment (by lizhong1008):

 VPP is supported from FFmpeg 3.3, scaling and deinterlacing filters were
 supported. And from ffmpeg 4.0, qsv overlay was supported.
 Here is a example of a qsv transcoding pipeline with
 decoding/scaling/encoding:
 ffmpeg -hwaccel qsv -c:v h264_qsv -i "testvid.mp4" -vf "scale_qsv=640:360"
 -b:v 800k -c:v h264_qsv -c:a copy -y "testoutput.mp4"
