C Specification

The structure VkVideoDecodeH264PictureInfoEXT representing a picture decode operation 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 the codec standard specific picture information from H.264 spec.

  • slicesCount is the number of slices in this picture.

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

Description

Valid Usage (Implicit)
