Expected behavior

The video will be played smoothly.

Actual behavior

Video plays with very low frame rate with many frames dropped.

When I tried to play the same video file with the debian repo version of mpv I reproduced the issue with following command: mpv --opengl-es=no K7iwGuBuJPo.mp4 and when I use yes then the playback is smooth (this is not the case with the git build version). The git build version does not use the --opengl-es option.

How I can make to work or is this a bug?

Try with --vd-lavc-dr=no

@CounterPillow : This is fixing my issue. Looks like I need to add it to the config. Thanks!

Yeah, this is a quirk with really low end Intel chips where directly decoding into the GPU buffer is somehow slower than an additional copy.

What CPU is this?
