Initially, I've filled ffmpeg bug since vaapi transcoding 10 bit > 8 bit was just failing, someone refereed to a "separated field of surfaces bug" which I couldn't find and offered patch which fixed the initial issue here: https://trac.ffmpeg.org/ticket/7764 After applying patch transcoding goes through with significant speed increase [from 2x to 7x] but the resulting output has flashing green overlay/glitch in upper half of the video. E.g from command" ffmpeg -threads 4 \ -init_hw_device vaapi=amd:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device amd -filter_hw_device amd \ -i trk.mkv \ -vf "scale_vaapi=format=nv12,hwupload" \ -c:v h264_vaapi -profile:v 578 \ -c:a copy -bf 0 -c:s copy \ -f mpegts -y plop.mkv Input is any 10 bit hevc video.
