C Specification

The VkVideoEncodeH265NaluSliceSegmentEXT structure representing a slice segment is defined as:

// Provided by VK_EXT_video_encode_h265
typedef struct VkVideoEncodeH265NaluSliceSegmentEXT {
    VkStructureType                                sType;
    const void*                                    pNext;
    uint32_t                                       ctbCount;
    const VkVideoEncodeH265ReferenceListsEXT*      pReferenceFinalLists;
    const StdVideoEncodeH265SliceSegmentHeader*    pSliceSegmentHeaderStd;
} VkVideoEncodeH265NaluSliceSegmentEXT;


  • sType is the type of this structure.

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

  • ctbCount is the number of CTBs in this slice segment.

  • pReferenceFinalLists is NULL or a pointer to a VkVideoEncodeH265ReferenceListsEXT structure specifying the reference lists to be used for the current slice segment. If pReferenceFinalLists is not NULL, these reference lists override the reference lists provided in VkVideoEncodeH265VclFrameInfoEXT::pReferenceFinalLists.

  • pSliceSegmentHeaderStd is a pointer to a StdVideoEncodeH265SliceSegmentHeader structure specifying the slice segment header for the current slice segment.


Valid Usage (Implicit)
  • VUID-VkVideoEncodeH265NaluSliceSegmentEXT-sType-sType

  • VUID-VkVideoEncodeH265NaluSliceSegmentEXT-pNext-pNext
    pNext must be NULL

  • VUID-VkVideoEncodeH265NaluSliceSegmentEXT-pReferenceFinalLists-parameter
    If pReferenceFinalLists is not NULL, pReferenceFinalLists must be a valid pointer to a valid VkVideoEncodeH265ReferenceListsEXT structure

  • VUID-VkVideoEncodeH265NaluSliceSegmentEXT-pSliceSegmentHeaderStd-parameter
    pSliceSegmentHeaderStd must be a valid pointer to a valid StdVideoEncodeH265SliceSegmentHeader value
