C Specification

To determine the number of combined image samplers required to support a multi-planar format, add VkSamplerYcbcrConversionImageFormatProperties to the pNext chain of the VkImageFormatProperties2 structure in a call to vkGetPhysicalDeviceImageFormatProperties2.

The VkSamplerYcbcrConversionImageFormatProperties structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkSamplerYcbcrConversionImageFormatProperties {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           combinedImageSamplerDescriptorCount;
} VkSamplerYcbcrConversionImageFormatProperties;

or the equivalent

// Provided by VK_KHR_sampler_ycbcr_conversion
typedef VkSamplerYcbcrConversionImageFormatProperties VkSamplerYcbcrConversionImageFormatPropertiesKHR;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • combinedImageSamplerDescriptorCount is the number of combined image sampler descriptors that the implementation uses to access the format.


Valid Usage (Implicit)
  • VUID-VkSamplerYcbcrConversionImageFormatProperties-sType-sType
