VkVideoEncodeH264QuantizationMapCapabilitiesKHR

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities of an H.264 encode profile, the VkVideoEncodeH264QuantizationMapCapabilitiesKHR structure can be included in the pNext chain of the VkVideoCapabilitiesKHR structure to retrieve additional video encode quantization map capabilities specific to H.264 encode profiles.

The VkVideoEncodeH264QuantizationMapCapabilitiesKHR structure is defined as:

typedef struct VkVideoEncodeH264QuantizationMapCapabilitiesKHR {
    VkStructureType sType;
    void* pNext;
    int32_t minQpDelta;
    int32_t maxQpDelta;
} VkVideoEncodeH264QuantizationMapCapabilitiesKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• minQpDelta indicates the minimum QP delta value supported for H.264 QP delta maps.
• maxQpDelta indicates the maximum QP delta value supported for H.264 QP delta maps.
