C Specification
The VkVideoEncodeH264ReferenceListsInfoEXT structure representing reference lists is defined as:
// Provided by VK_EXT_video_encode_h264
typedef struct VkVideoEncodeH264ReferenceListsInfoEXT {
VkStructureType sType;
const void* pNext;
uint8_t referenceList0EntryCount;
const VkVideoEncodeH264DpbSlotInfoEXT* pReferenceList0Entries;
uint8_t referenceList1EntryCount;
const VkVideoEncodeH264DpbSlotInfoEXT* pReferenceList1Entries;
const StdVideoEncodeH264RefMemMgmtCtrlOperations* pMemMgmtCtrlOperations;
} VkVideoEncodeH264ReferenceListsInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
referenceList0EntryCount
is the number of reference pictures in reference list L0 and is identical toStdVideoEncodeH264SliceHeader
::num_ref_idx_l0_active_minus1
+ 1. -
pReferenceList0Entries
is a pointer to an array ofreferenceList0EntryCount
VkVideoEncodeH264DpbSlotInfoEXT structures specifying the reference list L0 entries for the current picture. The entries provided must be ordered after all reference list L0 modification operations are applied (i.e. final list order). The entries provided must not reflect decoded picture marking operations in this frame that are applicable to references; the impact of such operations must be reflected in future frame encode commands. The slot index in each entry must match one of the slot indexes provided in thepReferenceSlots
of the parent VkVideoEncodeInfoKHR structure. -
referenceList1EntryCount
is the number of reference pictures in reference list L1 and is identical toStdVideoEncodeH264SliceHeader
::num_ref_idx_l1_active_minus1
+ 1. -
pReferenceList1Entries
is a pointer to an array ofreferenceList1EntryCount
VkVideoEncodeH264DpbSlotInfoEXT structures specifying the reference list L1 entries for the current picture. The entries provided must be ordered after all reference list L1 modification operations are applied (i.e. final list order). The entries provided must not reflect decoded picture marking operations in this frame that are applicable to references; the impact of such operations must be reflected in future frame encode commands. The slot index in each entry must match one of the slot indexes provided in thepReferenceSlots
of the parent VkVideoEncodeInfoKHR structure. -
pMemMgmtCtrlOperations
is a pointer to aStdVideoEncodeH264RefMemMgmtCtrlOperations
structure specifying reference lists modifications and decoded picture marking operations.
