VkVideoEncodeAV1QuantizationMapCapabilitiesKHR

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities of an AV1 encode profile, the VkVideoEncodeAV1QuantizationMapCapabilitiesKHR structure can be included in the pNext chain of the VkVideoCapabilitiesKHR structure to retrieve additional video encode quantization map capabilities specific to AV1 encode profiles.

The VkVideoEncodeAV1QuantizationMapCapabilitiesKHR structure is defined as:

typedef struct VkVideoEncodeAV1QuantizationMapCapabilitiesKHR {
    VkStructureType sType;
    void* pNext;
    int32_t minQIndexDelta;
    int32_t maxQIndexDelta;
} VkVideoEncodeAV1QuantizationMapCapabilitiesKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• minQIndexDelta indicates the minimum quantizer index delta value supported for AV1 quantizer index delta maps.
• maxQIndexDelta indicates the maximum quantizer index delta value supported for AV1 quantizer index delta maps.
