VkSamplerYcbcrConversionInfo

To create a sampler with Y′C_BC_R conversion enabled, add a VkSamplerYcbcrConversionInfo structure to the pNext chain of the VkSamplerCreateInfo structure. To create a sampler Y′C_BC_R conversion, the samplerYcbcrConversion feature must be enabled. Conversion must be fixed at pipeline creation time, through use of a combined image sampler with an immutable sampler in VkDescriptorSetLayoutBinding.

A VkSamplerYcbcrConversionInfo must be provided for samplers to be used with image views that access VK_IMAGE_ASPECT_COLOR_BIT if the format is one of the formats that require a sampler Y′C_BC_R conversion , or if the image view has an external format .

The VkSamplerYcbcrConversionInfo structure is defined as:

typedef struct VkSamplerYcbcrConversionInfo {
    VkStructureType sType;
    const void* pNext;
    VkSamplerYcbcrConversion conversion;
} VkSamplerYcbcrConversionInfo;

or the equivalent

typedef VkSamplerYcbcrConversionInfo VkSamplerYcbcrConversionInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• conversion is a VkSamplerYcbcrConversion handle created with vkCreateSamplerYcbcrConversion.
