Description

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 ​https://git.libav.org/?p=libav.git;a=patch;h=8a62d2c28fbacd1ae20c35887a1eecba2be14371 to the current ffmpeg git master fixed the problem for me - please consider something like this for merging.
