  • Article

The D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MAP_0095 structure contains segmentation map information for an AV1 frame.

Syntax

typedef struct D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MAP_0095 {
  UINT  SegmentsMapByteSize;
  UINT8 *pSegmentsMap;
} D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MAP_0095;

Members

SegmentsMapByteSize

Size in bytes of the pSegmentsMap buffer.

pSegmentsMap

In raster order, contains the AV1 syntax segment_id between [0..7] for each block in the frame. The block size is SegmentationBlockSize as reported by the driver in D3D12DDI_VIDEO_ENCODER_AV1_CODEC_CONFIGURATION_SUPPORT_0095.
