Loading… please wait.

## C Specification

The VkVideoEncodeH265NaluSliceSegmentInfoEXT structure representing a slice segment is defined as:

    // Provided by VK_EXT_video_encode_h265
    typedef struct VkVideoEncodeH265NaluSliceSegmentInfoEXT {
        VkStructureType                                  sType;
        const void*                                      pNext;
        uint32_t                                         ctbCount;
        const VkVideoEncodeH265ReferenceListsInfoEXT*    pReferenceFinalLists;
        const StdVideoEncodeH265SliceSegmentHeader*      pSliceSegmentHeaderStd;
    } VkVideoEncodeH265NaluSliceSegmentInfoEXT;

## Members

- `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 VkVideoEncodeH265ReferenceListsInfoEXT 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.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeH265NaluSliceSegmentInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_NALU_SLICE_SEGMENT_INFO_EXT`

- VUID-VkVideoEncodeH265NaluSliceSegmentInfoEXT-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkVideoEncodeH265NaluSliceSegmentInfoEXT-pReferenceFinalLists-parameter
  If `pReferenceFinalLists` is not `NULL`, `pReferenceFinalLists` must be a valid pointer to a valid VkVideoEncodeH265ReferenceListsInfoEXT structure

- VUID-VkVideoEncodeH265NaluSliceSegmentInfoEXT-pSliceSegmentHeaderStd-parameter
  `pSliceSegmentHeaderStd` must be a valid pointer to a valid `StdVideoEncodeH265SliceSegmentHeader` value
