C Specification

The VkVideoEncodeH264NaluSliceEXT structure representing a slice is defined as:

// Provided by VK_EXT_video_encode_h264
typedef struct VkVideoEncodeH264NaluSliceEXT {
    VkStructureType                              sType;
    const void*                                  pNext;
    uint32_t                                     mbCount;
    const VkVideoEncodeH264ReferenceListsEXT*    pReferenceFinalLists;
    const StdVideoEncodeH264SliceHeader*         pSliceHeaderStd;
} VkVideoEncodeH264NaluSliceEXT;

Members

  • sType is the type of this structure.

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

  • mbCount is the number of macroblocks in this slice.

  • pReferenceFinalLists is NULL or a pointer to a VkVideoEncodeH264ReferenceListsEXT structure specifying the reference lists to be used for the current slice. If pReferenceFinalLists is not NULL, these reference lists override the reference lists provided in VkVideoEncodeH264VclFrameInfoEXT::pReferenceFinalLists.

  • pSliceHeaderStd is a pointer to a StdVideoEncodeH264SliceHeader structure specifying the slice header for the current slice.

Description

Valid Usage (Implicit)
  • VUID-VkVideoEncodeH264NaluSliceEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_NALU_SLICE_EXT

  • VUID-VkVideoEncodeH264NaluSliceEXT-pNext-pNext
    pNext must be NULL

  • VUID-VkVideoEncodeH264NaluSliceEXT-pReferenceFinalLists-parameter
    If pReferenceFinalLists is not NULL, pReferenceFinalLists must be a valid pointer to a valid VkVideoEncodeH264ReferenceListsEXT structure

  • VUID-VkVideoEncodeH264NaluSliceEXT-pSliceHeaderStd-parameter
    pSliceHeaderStd must be a valid pointer to a valid StdVideoEncodeH264SliceHeader value
