C Specification

The VkVideoEncodeH264DpbSlotInfoEXT structure correlates a DPB Slot index with codec-specific information and is defined as:

// Provided by VK_EXT_video_encode_h264
typedef struct VkVideoEncodeH264DpbSlotInfoEXT {
    VkStructureType                         sType;
    const void*                             pNext;
    int8_t                                  slotIndex;
    const StdVideoEncodeH264PictureInfo*    pStdPictureInfo;
} VkVideoEncodeH264DpbSlotInfoEXT;


  • sType is the type of this structure.

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

  • slotIndex is the slot index for this picture. slotIndex must match the slotIndex in pSetupReferenceSlot of VkVideoEncodeInfoKHR in the command used to encode the corresponding picture.

  • pStdPictureInfo is a pointer to a StdVideoEncodeH264PictureInfo structure specifying codec standard specific syntax/information associated with this picture from the H.264 specification.


Valid Usage (Implicit)
  • VUID-VkVideoEncodeH264DpbSlotInfoEXT-sType-sType

  • VUID-VkVideoEncodeH264DpbSlotInfoEXT-pNext-pNext
    pNext must be NULL

  • VUID-VkVideoEncodeH264DpbSlotInfoEXT-pStdPictureInfo-parameter
    pStdPictureInfo must be a valid pointer to a valid StdVideoEncodeH264PictureInfo value
