May 31st, 2023, Vulkan decoding

+ 

+    Recently, Vulkan-powered decoding hardware acceleration code was merged into the codebase. +    This is the first vendor-generic and platform-generic decode acceleration API, enabling the +    same code to be used on multiple platforms, with very minimal overhead. +    This is also the first multi-threaded hardware decoding API, and our code makes full use of this, +    saturating all available decode engines the hardware exposes. + 

+ 

+    Those wishing to test the code can consult our +    documentation page. +    For those who would like to integrate FFmpeg's Vulkan code to demux, parse, decode, and receive +    a VkImage to present or manipulate, documentation and examples are available in our source tree. + 

+ 

+    As this is also the first practical implementation of the specifications, bugs may be present, +    particularly in drivers, and, although passing verification, the implementation itself. +
