C Specification

The VkVideoEncodeH265VclFrameInfoEXT structure representing a frame encode operation is defined as:

// Provided by VK_EXT_video_encode_h265
typedef struct VkVideoEncodeH265VclFrameInfoEXT {
    VkStructureType                                sType;
    const void*                                    pNext;
    const VkVideoEncodeH265ReferenceListsEXT*      pReferenceFinalLists;
    uint32_t                                       naluSliceSegmentEntryCount;
    const VkVideoEncodeH265NaluSliceSegmentEXT*    pNaluSliceSegmentEntries;
    const StdVideoEncodeH265PictureInfo*           pCurrentPictureInfo;
} VkVideoEncodeH265VclFrameInfoEXT;

Members

  • sType is the type of this structure.

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

  • pReferenceFinalLists is NULL or a pointer to a VkVideoEncodeH265ReferenceListsEXT structure specifying the reference lists to be used for the current picture.

  • naluSliceSegmentEntryCount is the number of slice segment NALUs in the frame.

  • pNaluSliceSegmentEntries is a pointer to an array of VkVideoEncodeH265NaluSliceSegmentEXT structures specifying the division of the current picture into slice segments and the properties of these slice segments.

  • pCurrentPictureInfo is a pointer to a StdVideoEncodeH265PictureInfo structure specifying the syntax and other codec-specific information from the H.265 specification, associated with this picture.

Description

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH265VclFrameInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_VCL_FRAME_INFO_EXT

  • VUID-VkVideoEncodeH265VclFrameInfoEXT-pReferenceFinalLists-parameter
    If pReferenceFinalLists is not NULL, pReferenceFinalLists must be a valid pointer to a valid VkVideoEncodeH265ReferenceListsEXT structure

  • VUID-VkVideoEncodeH265VclFrameInfoEXT-pNaluSliceSegmentEntries-parameter
    pNaluSliceSegmentEntries must be a valid pointer to an array of naluSliceSegmentEntryCount valid VkVideoEncodeH265NaluSliceSegmentEXT structures

  • VUID-VkVideoEncodeH265VclFrameInfoEXT-pCurrentPictureInfo-parameter
    pCurrentPictureInfo must be a valid pointer to a valid StdVideoEncodeH265PictureInfo value

  • VUID-VkVideoEncodeH265VclFrameInfoEXT-naluSliceSegmentEntryCount-arraylength
    naluSliceSegmentEntryCount must be greater than 0
