C Specification
To create a sampler with Y’CBCR conversion enabled, add a
VkSamplerYcbcrConversionInfo to the pNext
chain of the
VkSamplerCreateInfo structure.
To create a sampler Y’CBCR 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 appears in https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#formats-requiring-sampler-ycbcr-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;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific structure. -
conversion
is a VkSamplerYcbcrConversion handle created with vkCreateSamplerYcbcrConversion.
