Khronos Finalizes Vulkan Video Extensions for Accelerated H.264 and H.265 Encode

The December 2022 release of Vulkan 1.3.238 saw the finalization of the extensions to decode H.264 and H.265, and today, with the release of Vulkan 1.3.274, Khronos has finalized their counterpart: the extensions to enable encoding of H.264 and H.265 video streams.

Copying Images on the Host in Vulkan

The Vulkan Working Group has released the VK_EXT_host_image_copy extension, allowing copies to and from images to be done on the host rather than the device.

Mesh Shading for Vulkan

With the release of the VK_EXT_mesh_shader extension Vulkan gets an alternative geometry rasterization pipeline. This extension brings cross-vendor mesh shading to Vulkan, with a focus on improving functional compatibility with DirectX 12.

Khronos has introduced a new extension named VK_EXT_graphics_pipeline_library that allows for shaders to be compiled much earlier than at full Pipeline State Object (PSO) creation time. By leveraging this extension, I was able to avoid many causes of frame hitches due to PSOs being late-created at draw time in the Source 2 Vulkan renderer.
