D3D12DDI_VIDEO_DECODE_PARAMETER_TYPE_0020 enumeration

Description

The D3D12DDI_VIDEO_DECODE_PARAMETER_TYPE_0020 enumeration identifies the type of data thatD3D12DDI_VIDEO_DECODE_FRAME_ARGUMENT_0020->pData

Contains the video decode parameter type.

Constants

`D3D12DDI_VIDEO_DECODE_PARAMETER_TYPE_0020_PICTURE_PARAMETERS`

Picture decoding parameter buffer.

`D3D12DDI_VIDEO_DECODE_PARAMETER_TYPE_0020_INVERSE_QUANTIZATION_MATRIX`

Inverse quantization matrix buffer.

`D3D12DDI_VIDEO_DECODE_PARAMETER_TYPE_0020_SLICE_CONTROL`

The slice-level parameters of a slice of bitstream data, for off-host bitstream compressed picture decoding.

`D3D12DDI_VIDEO_DECODE_PARAMETER_TYPE_0097_HUFFMAN_TABLE`

pData points to a Huffman table buffer.

Remarks

The definition of each buffer type is dependent upon the decode profile and is defined in each codec specification.
