C Specification

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:

// Provided by VK_KHR_video_encode_h264 with VK_KHR_video_encode_quantization_map
typedef struct VkVideoEncodeH264QuantizationMapCapabilitiesKHR {
    VkStructureType    sType;
    void*              pNext;
    int32_t            minQpDelta;
    int32_t            maxQpDelta;
} VkVideoEncodeH264QuantizationMapCapabilitiesKHR;

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.264 QP delta maps.

  • maxQpDelta indicates the maximum QP delta value supported for H.264 QP delta maps.

Description

Valid Usage (Implicit)
  • VUID-VkVideoEncodeH264QuantizationMapCapabilitiesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_QUANTIZATION_MAP_CAPABILITIES_KHR
