## Description

This extension adds some Y′CBCR formats that are in common use for video encode and decode, but were not part of the `VK_KHR_sampler_ycbcr_conversion` extension.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceYcbcr2Plane444FormatsFeaturesEXT

## New Enum Constants

- `VK_EXT_YCBCR_2PLANE_444_FORMATS_EXTENSION_NAME`

- `VK_EXT_YCBCR_2PLANE_444_FORMATS_SPEC_VERSION`

- Extending VkFormat:

  - `VK_FORMAT_G10X6_B10X6R10X6_2PLANE_444_UNORM_3PACK16_EXT`

  - `VK_FORMAT_G12X4_B12X4R12X4_2PLANE_444_UNORM_3PACK16_EXT`

  - `VK_FORMAT_G16_B16R16_2PLANE_444_UNORM_EXT`

  - `VK_FORMAT_G8_B8R8_2PLANE_444_UNORM_EXT`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_YCBCR_2_PLANE_444_FORMATS_FEATURES_EXT`

## Promotion to Vulkan 1.3

The format enumerants introduced by the extension are included in core Vulkan 1.3, with the EXT suffix omitted. However, runtime support for these formats is optional in core Vulkan 1.3, while if this extension is supported, runtime support is mandatory. The feature structure is not promoted. The original enum names are still available as aliases of the core functionality.
