<pre>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:
<a href="https://trac.ffmpeg.org/ticket/7764">https://trac.ffmpeg.org/ticket/7764</a>
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.
