Hi Mark,
I couldn't reproduce the issue on my Polaris 11 to run mpv / ffmpeg
about 1.5 hours.
one terminal run:
ffmpeg -y -hwaccel vaapi -hwaccel_device /dev/dri/renderD128
-hwaccel_output_format vaapi -i video/Mr.Right.mp4 -an -c:v hevc_vaapi
-bf 0 out.mp4
the other terminal run:
mpv --fs --loop --no-audio --vo gpu --gpu-context=x11egl --hwdec=vaapi
video/Mr.Right.mp4
But it has some failure with vaDeriveImage. I am not sure if this
failure matters, the video still can play without any other error,
mpv --fs --loop --no-audio --vo vaapi --hwdec=vaapi video/Mr.Right.mp4
No error reported with this command line.
