C Specification
The VkVideoEncodeH264VclFrameInfoEXT structure representing a frame encode operation is defined as:
// Provided by VK_EXT_video_encode_h264
typedef struct VkVideoEncodeH264VclFrameInfoEXT {
VkStructureType sType;
const void* pNext;
const VkVideoEncodeH264ReferenceListsEXT* pReferenceFinalLists;
uint32_t naluSliceEntryCount;
const VkVideoEncodeH264NaluSliceEXT* pNaluSliceEntries;
const StdVideoEncodeH264PictureInfo* pCurrentPictureInfo;
} VkVideoEncodeH264VclFrameInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
pReferenceFinalLists
isNULL
or a pointer to a VkVideoEncodeH264ReferenceListsEXT structure specifying the reference lists to be used for the current picture. -
naluSliceEntryCount
is the number of slice NALUs in the frame. -
pNaluSliceEntries
is a pointer to an array ofnaluSliceEntryCount
VkVideoEncodeH264NaluSliceEXT structures specifying the division of the current picture into slices and the properties of these slices. This is an ordered sequence; the NALUs are generated consecutively in VkVideoEncodeInfoKHR::dstBitstreamBuffer
in the same order as in this array. -
pCurrentPictureInfo
is a pointer to aStdVideoEncodeH264PictureInfo
structure specifying the syntax and other codec-specific information from the H.264 specification associated with this picture. The information provided must reflect the decoded picture marking operations that are applicable to this frame.
