C Specification

The VkVideoDecodeH264PictureInfoEXT structure represents a picture decode operation and is defined as:

// Provided by VK_EXT_video_decode_h264
typedef struct VkVideoDecodeH264PictureInfoEXT {
    VkStructureType                         sType;
    const void*                             pNext;
    const StdVideoDecodeH264PictureInfo*    pStdPictureInfo;
    uint32_t                                slicesCount;
    const uint32_t*                         pSlicesDataOffsets;
} VkVideoDecodeH264PictureInfoEXT;

Members

  • sType is the type of this structure.

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

  • pStdPictureInfo is a pointer to a StdVideoDecodeH264PictureInfo structure specifying the codec standard specific picture information from the H.264 specification.

  • slicesCount is the number of slices in this picture.

  • pSlicesDataOffsets is a pointer to an array of slicesCount offsets indicating the start offset of each slice within the bitstream buffer.

Description

Valid Usage (Implicit)

  • VUID-VkVideoDecodeH264PictureInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H264_PICTURE_INFO_EXT

  • VUID-VkVideoDecodeH264PictureInfoEXT-pStdPictureInfo-parameter
    pStdPictureInfo must be a valid pointer to a valid StdVideoDecodeH264PictureInfo value

  • VUID-VkVideoDecodeH264PictureInfoEXT-pSlicesDataOffsets-parameter
    pSlicesDataOffsets must be a valid pointer to an array of slicesCount uint32_t values

  • VUID-VkVideoDecodeH264PictureInfoEXT-slicesCount-arraylength
    slicesCount must be greater than 0
