Description gregory shu 2019-07-11 16:35:15 UTC 
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.
