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).
