[Cin] Still on hardware acceleration

[Andrea paz]

Thanks for the links, very interesting talks from AMD developers and
ffmpeg. Unfortunately for video AMD is far behind Nvidia and now
Intel. Mpv I've already managed to get it working with Vulkan and so
far I haven't had any problems (apart from the "noise" of the GPU
fans)
I also see little difference between vaapi decoder and "none".
Sometimes you can see a small advantage though.
For Vulkan, I guess I will wait for ffmpeg 6.1, hoping the bug will be fixed.
