Hi Boyuan,
I have tried the patch in my R5 2400G(ArchLinux, mesa-19.0.4).
Segment fault is gone, but new issue is found.
reproduce:
No more segment fault when using ffmpeg to produce hevc stream.
ffmpeg -vaapi_device /dev/dri/renderD128 -i input.avi -vf
'format=nv12,hwupload' -c:v hevc_vaapi -bf 0 -g 7 output.mp4
But Some error messages is shown when decoding the encoded stream.
$ mpv output.mp4
Playing: output.mp4
(+) Video --vid=1 (*) (hevc 1920x1080 23.976fps)
(+) Audio --aid=1 (*) (aac 2ch 48000Hz)
Using hardware decoding (vaapi).
