public class VkVideoDecodeH265DpbSlotInfoKHR
extends org.lwjgl.system.Struct<VkVideoDecodeH265DpbSlotInfoKHR>
implements org.lwjgl.system.NativeResource

Structure specifies H.265 DPB information when decoding a frame.

Description

This structure is specified in the pNext chain of VkVideoDecodeInfoKHR::pSetupReferenceSlot, if not NULL, and the pNext chain of the elements of VkVideoDecodeInfoKHR::pReferenceSlots to specify the codec-specific reference picture information for an H.265 decode operation.

Active Reference Picture Information

• The image subregion used is determined according to the H.265 Decode Picture Data Access section.
• The reference picture is associated with the DPB slot index specified in the slotIndex member of the corresponding element of VkVideoDecodeInfoKHR::pReferenceSlots.
• The reference picture is associated with the H.265 reference information provided in pStdReferenceInfo.

Reconstructed Picture Information

• The image subregion used is determined according to the H.265 Decode Picture Data Access section.
• If reference picture setup is requested, then the reconstructed picture is used to activate the DPB slot with the index specified in VkVideoDecodeInfoKHR::pSetupReferenceSlot→slotIndex.
• The reconstructed picture is associated with the H.265 reference information provided in pStdReferenceInfo.

Std Reference Information

• flags.used_for_long_term_reference is used to indicate whether the picture is marked as “used for long-term reference” as defined in section 8.3.2 of the ITU-T H.265 Specification;
• flags.unused_for_reference is used to indicate whether the picture is marked as “unused for reference” as defined in section 8.3.2 of the ITU-T H.265 Specification;
• all other members are interpreted as defined in section 8.3 of the ITU-T H.265 Specification.

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_VIDEO_DECODE_H265_DPB_SLOT_INFO_KHR
• pStdReferenceInfo must be a valid pointer to a valid StdVideoDecodeH265ReferenceInfo value

 struct VkVideoDecodeH265DpbSlotInfoKHR {
     VkStructureType sType();
     void const * pNext();
     StdVideoDecodeH265ReferenceInfo const * pStdReferenceInfo();
