C Specification

The VkVideoEncodeH264DpbSlotInfoEXT structure, representing a reconstructed picture that is being used as a reference picture, is defined as:

// Provided by VK_EXT_video_encode_h264
typedef struct VkVideoEncodeH264DpbSlotInfoEXT {
    VkStructureType                           sType;
    const void*                               pNext;
    int8_t                                    slotIndex;
    const StdVideoEncodeH264ReferenceInfo*    pStdReferenceInfo;
} VkVideoEncodeH264DpbSlotInfoEXT;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • slotIndex is the DPB Slot index for this picture. slotIndex must match the slotIndex in pSetupReferenceSlot of VkVideoEncodeInfoKHR in the command used to encode the corresponding picture.

  • pStdReferenceInfo is a pointer to a StdVideoEncodeH264ReferenceInfo structure specifying the syntax and other codec-specific information from the H.264 specification associated with this reference picture.

Description

Valid Usage (Implicit)
  • VUID-VkVideoEncodeH264DpbSlotInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_DPB_SLOT_INFO_EXT

  • VUID-VkVideoEncodeH264DpbSlotInfoEXT-pNext-pNext
    pNext must be NULL

  • VUID-VkVideoEncodeH264DpbSlotInfoEXT-pStdReferenceInfo-parameter
    pStdReferenceInfo must be a valid pointer to a valid StdVideoEncodeH264ReferenceInfo value
