tried the command that you provided, the output was following:

-i :0 -vf 'format=nv12,hwupload' -c:v h264_vaapi -b:v 7M -profile 578 -bf 0

Then i have replaced -profile 578 option that you provided with a suggested
-profile:v main, and the output was the following
ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1920x1080
-i :0 -vf 'format=nv12,hwupload' -c:v h264_vaapi -b:v 7M -profile:v main
-bf 0 output.mp4

P.S. i would like to use Vulkan anything, but i believe my GPU doesn't
support Vulkan API
