Members

FullFrameIdentical

Indicates the current frame is a repeat frame from the frame referenced by SourceDPBFrameReference. When TRUE, pDirtyRects must be NULL.

MapValuesType

A D3D12_VIDEO_ENCODER_DIRTY_REGIONS_MAP_VALUES_MODE indicating the semantic of the values of pDirtyRects.

NumDirtyRects

Number of elements in pDirtyRects.

pDirtyRects

Pointer to an array of RECT structures. Each rect indicates pixels at those positions are different or identical to pixels in the same positions of the previous frame referenced by SourceDPBFrameReference.

SourceDPBFrameReference

An index into the picture parameters DPB descriptor indicating which previous reference frame this dirty region refers to.
