C Specification

The VkVideoEncodeH265NaluSliceSegmentInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_h265
typedef struct VkVideoEncodeH265NaluSliceSegmentInfoKHR {
    VkStructureType                                sType;
    const void*                                    pNext;
    int32_t                                        constantQp;
    const StdVideoEncodeH265SliceSegmentHeader*    pStdSliceSegmentHeader;
} VkVideoEncodeH265NaluSliceSegmentInfoKHR;

Members

Description

Std Slice Segment Header Parameters

The members of the StdVideoEncodeH265SliceSegmentHeader structure pointed to by pStdSliceSegmentHeader are interpreted as follows:

  • flags.reserved and reserved1 are used only for padding purposes and are otherwise ignored;

  • if pWeightTable is not NULL, then it is a pointer to a StdVideoEncodeH265WeightTable that is interpreted as follows:

    • flags.luma_weight_l0_flag, flags.chroma_weight_l0_flag, flags.luma_weight_l1_flag, and flags.chroma_weight_l1_flag are bitmasks where bit index i corresponds to luma_weight_l0_flag[i], chroma_weight_l0_flag[i], luma_weight_l1_flag[i], and chroma_weight_l1_flag[i], respectively, as defined in section 7.4.7.3 of the ITU-T H.265 Specification;

    • all other members of StdVideoEncodeH265WeightTable are interpreted as defined in section 7.4.7.3 of the ITU-T H.265 Specification;

  • all other members are interpreted as defined in section 7.4.7.1 of the ITU-T H.265 Specification.

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH265NaluSliceSegmentInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_NALU_SLICE_SEGMENT_INFO_KHR

  • VUID-VkVideoEncodeH265NaluSliceSegmentInfoKHR-pNext-pNext
    pNext must be NULL

  • VUID-VkVideoEncodeH265NaluSliceSegmentInfoKHR-pStdSliceSegmentHeader-parameter
    pStdSliceSegmentHeader must be a valid pointer to a valid StdVideoEncodeH265SliceSegmentHeader value
