Comment (by wenbin,chen):
there is another option to make cmd work:
{{{
ffmpeg -init_hw_device qsv -hwaccel_output_format nv12 -c:v h264_qsv -i
in.mp4 -loop 1 -r 30 -i overlay.png -filter_complex
'[0:v]hwupload=extra_hw_frames=64[temp];[1:v]hwupload=extra_hw_frames=64,format=qsv[ov];[temp][ov]overlay_qsv,format=nv12'
-c:v h264_qsv -y out.mp4
}}}
