When I use mpv to play 4k video, it loses a lot of frames, so I try to solve it.
the cli log
I write
hwdec=auto into mpv.conf, but it seems to not work.nvtop can’t monitor the intel gpu, so I use intel_gpu_top to check it.when I change play speed to 1.5x, it behaves like this.
but after acc to 2x, it decrease.
思考了下觉得是驱动没安装
继续思考觉得是需要 vp9 的编解码器
-S intel-media-driver 后 vainfo 出了结果然后重试，非常顺利。
and
intel_gpu_top show the video works now.
