Members

NodeIndex

In multi-adapter operation, this indicates which physical adapter of the device this operation applies to.

Codec

A member of the D3D12_VIDEO_ENCODER_CODEC enumeration specifying the codec for which resource requirements are being queried.

Profile

A D3D12_VIDEO_ENCODER_PROFILE_DESC structure specifying the profile for which resource requirements are being queried.

InputFormat

A DXGI_FORMAT structure representing the input format for which resource requirements are being queried.

PictureTargetResolution

A D3D12_VIDEO_ENCODER_PICTURE_RESOLUTION_DESC structure representing the resolution for which resource requirements are being queried.

IsSupported

Receives a boolean value indicating if the specified parameters are supported.

CompressedBitstreamBufferAccessAlignment

Receives a UINT indicating the alignment required in bytes for the resource to be passed in D3D12_VIDEO_ENCODER_COMPRESSED_BITSTREAM.pBuffer and D3D12_VIDEO_ENCODER_COMPRESSED_BITSTREAM.Offset. If no alignment is required, 1 should is returned to indicate 1 byte (trivial) alignment.

EncoderMetadataBufferAccessAlignment

Receives a UINT indicating the alignment required in bytes for the resource to be passed in D3D12_VIDEO_ENCODER_OUTPUT_ARGUMENTS.pEncoderOutputMetadata. If no alignment required, 1 should be reported to convey 1 byte (trivial) alignment.

MaxEncoderOutputMetadataBufferSize

Receives a UINT indicating the maximum size in bytes needed for the ID3D12Resource that will be allocated by the host and used as output in the EncodeFrame for output encoder metadata based on the input arguments.
