Members

FullFrameIdentical

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

MapValuesType

A D3D12_VIDEO_ENCODER_DIRTY_REGIONS_MAP_VALUES_MODE indicating the semantic of the values of pDirtyRegionsMap.

pDirtyRegionsMap

Pointer to an ID3D12Resource texture with the same dimensions as the input frame and format DXGI_FORMAT_R8_UINT. Each (x, y) position indicates if the pixel at that position is different or identical to a pixel in the same position of the previous frame in the DPB used as reference.

SourceDPBFrameReference

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