       | That's good.
       | 
       | By the way, mpv already supports Vulkan video decoding:

       | 
       | Now we need OBS and Firefox supporting Vulkan video too.

           | On Linux it should be a better option than VAAPI once drivers
           | will support it. Since Firefox is using ffmpeg anyway, it
           | probably shouldn't be too hard to make it an option.

             | Decoding h264/h265 in fixed (CPU) hardware is much more
             | efficient than on the GPU.
             | 
             | Don't get me wrong, its still miles and miles better than
             | software decode.
