I tried the following command with vpp_qsv filter but pixel format/colorspace
of the output is the same:
====
ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -v verbose -f x11grab
-draw_mouse 0 -framerate 20 -probesize 42M -video_size 1920x1200
-thread_queue_size 1000 -vcodec rawvideo -i ":0.0" -an -vf
'hwupload=extra_hw_frames=64,vpp_qsv=format=bgra' -c:v hevc_qsv -preset
veryslow -global_quality 17 -look_ahead 1 -y /tmp/output.mkv
====
The ffprobe result for the above command is:
====
