Unfortunately, this commit couldn't fix the initial problem.
1. Result video is jerky if it grabbed and encoded with ffmpeg
(h264_vaapi codec).
2. OBS still crashed if I try to record or stream video.
3. In the kernel log still appears the message "amdgpu: [mmhub] page
fault (src_id:0 ring:0 vmid:4 pasid:32770, for process obs" if I tried
to record or stream video by OBS.
