Vulkan encode is quite soon going to get all features needed to allow for
all vendor-specific optimizations to be exposed, though I think you should
already be in the loop.
Is there a reason to add this code in now? AMF is still hardly that used,
at least in the Linux world, as it isn't really packaged everywhere,
and on Windows, D3D12 is gaining more traction.
AMD has also already released all FSR-based code for upscaling.
