C Specification

The VkVideoEncodeH264NaluSliceInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_h264
typedef struct VkVideoEncodeH264NaluSliceInfoKHR {
    VkStructureType                         sType;
    const void*                             pNext;
    int32_t                                 constantQp;
    const StdVideoEncodeH264SliceHeader*    pStdSliceHeader;
} VkVideoEncodeH264NaluSliceInfoKHR;

Members

Description

Std Slice Header Parameters

The members of the StdVideoEncodeH264SliceHeader structure pointed to by pStdSliceHeader 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 StdVideoEncodeH264WeightTable that is interpreted as follows:

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

    • all other members of StdVideoEncodeH264WeightTable are interpreted as defined in section 7.4.3.2 of the ITU-T H.264 Specification;

  • all other members are interpreted as defined in section 7.4.3 of the ITU-T H.264 Specification.

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH264NaluSliceInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_NALU_SLICE_INFO_KHR

  • VUID-VkVideoEncodeH264NaluSliceInfoKHR-pNext-pNext
    pNext must be NULL

  • VUID-VkVideoEncodeH264NaluSliceInfoKHR-pStdSliceHeader-parameter
    pStdSliceHeader must be a valid pointer to a valid StdVideoEncodeH264SliceHeader value
