Description
Vulkan Video is aiming to be an industry-standard cross-platform interface to video decode/encode hardware (and probably also software).
I'm proposing adding support for using Vulkan Video as a new ffmpeg codec backend. (probably a better way to describe that...)
They (as of 2021-04-14) have provisional support for encode/decode for h.264 and decode for h.265, they are planning on shortly gaining support for encode for h.265, decode for vp9, and encode/decode for av1.
An Introduction to Vulkan Video - The Khronos Group Inc
Supporting Vulkan Video would allow hardware vendors (such as the Libre-SOC project, which I'm part of) to only need to implement each codec once, rather than N times for each of N different software libraries that need support.
Funding may be available from Libre-SOC, will have to check.

Decoding implemented and merged in git master.
I've implemented encoding, but the spec is still in beta, and there are large issues with it that have to be addressed before it can be usable and merged.
