C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR to query the capabilities of an H.265 encode profile, the VkVideoEncodeH265QuantizationMapCapabilitiesKHR structure can be included in the pNext chain of the VkVideoCapabilitiesKHR structure to retrieve additional video encode quantization map capabilities specific to H.265 encode profiles.

The VkVideoEncodeH265QuantizationMapCapabilitiesKHR structure is defined as:

// Provided by VK_KHR_video_encode_h265 with VK_KHR_video_encode_quantization_map
typedef struct VkVideoEncodeH265QuantizationMapCapabilitiesKHR {
    VkStructureType    sType;
    void*              pNext;
    int32_t            minQpDelta;
    int32_t            maxQpDelta;
} VkVideoEncodeH265QuantizationMapCapabilitiesKHR;

Members

  • 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.265 QP delta maps.

  • maxQpDelta indicates the maximum QP delta value supported for H.265 QP delta maps.

Description

Valid Usage (Implicit)
  • VUID-VkVideoEncodeH265QuantizationMapCapabilitiesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_QUANTIZATION_MAP_CAPABILITIES_KHR
