Summary of the bug:
When encoding high quality 4k video files (from raw camera material) I
encounter image corruptions after the first few I-frames in the output.
How to reproduce:
ffmpeg -vaapi_device /dev/dri/renderD128 -i some_4k_video.mp4 -vf
'format=nv12,hwupload' -f matroska -qp 12 -vcodec h264_vaapi output.mkv
Applying the patch from

to the current ffmpeg git master fixed the problem for me - please
consider something like this for merging.
