Sorry for my poor english……

I have tested chromium 83 which supported hardware acceleration perfectly

But newer chromium won`t do that.

I tested mpv with --hwdec=vaapi, no hardware acceleration.

But mpv with --hwdec=vaapi-copy, hardware acceleration perfectly.

Maybe chromium has the same problem?

Do you know what the difference is between vaapi and vaapi-copy?

copies video back into system RAM，

performance loss but decoding with GPU

This maybe a problem with the graphics card driver

Is it possible to fallback to vaapi-copy when vaapi is not available？

Closing as hardware acceleration was reported to be working.
