 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.

 Supporting Vulkan Video would allow hardware vendors (such as the [https
 ://libre-soc.org/ 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.
