VkVideoEncodeQuantizationMapCapabilitiesKHR

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR with pVideoProfile→videoCodecOperation specifying an encode operation, the VkVideoEncodeQuantizationMapCapabilitiesKHR structure can be included in the pNext chain of the VkVideoCapabilitiesKHR structure to retrieve capabilities specific to video encode quantization maps.

The VkVideoEncodeQuantizationMapCapabilitiesKHR structure is defined as:

typedef struct VkVideoEncodeQuantizationMapCapabilitiesKHR {
    VkStructureType sType;
    void* pNext;
    VkExtent2D maxQuantizationMapExtent;
} VkVideoEncodeQuantizationMapCapabilitiesKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• maxQuantizationMapExtent indicates the maximum supported width and height of quantization maps.
