Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddi_video_encoder_picture_control_subregions_layout_data_0080_2)

Description

The D3D12DDI_VIDEO_ENCODER_PICTURE_CONTROL_SUBREGIONS_LAYOUT_DATA_0080_2 structure defines picture control subregions as slices.

Members

`DataSize`

Size of the reference data, in bytes.

`pSlicesPartition_H264`

Pointer to a D3D12DDI_VIDEO_ENCODER_PICTURE_CONTROL_SUBREGIONS_LAYOUT_DATA_SLICES_0080 structure that defines subregions as slices for H.264 encoding.

`pSlicesPartition_HEVC`

Pointer to a D3D12DDI_VIDEO_ENCODER_PICTURE_CONTROL_SUBREGIONS_LAYOUT_DATA_SLICES_0080 structure that defines subregions as slices for HEVC encoding.

`pTilesPartition_AV1`

Pointer to a D3D12DDI_VIDEO_ENCODER_AV1_PICTURE_CONTROL_SUBREGIONS_LAYOUT_DATA_TILES_0095 structure that defines subregions as tiles for AV1 encoding. Added in Windows 11, version 24H2 (WDDM 3.2).

Remarks

See D3D12 video encoding for general information.
