Hi, i was recently trying out vaapi acceleration in ffmpeg. It works well
with h264 hevc and vp8, but not with vp9. The output i get is:

ffmpeg -vaapi_device /dev/dri/renderD128v -i in.mkv -vf
'format=nv12,hwupload' -c:v vp9_vaapi -b:v 5M out.webm
[ vp9_vaapi ] Encoding profile not found (19).

Also, how can i encode rgb ( bgrp, bgr0 ) while recording with hardware
acceleration ( h264), not losing quality in yuv?
