Members

NodeIndex

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

CommandId

The unique identifier for the video extension command for which support is queried.

pInputData

Input data for the capability query allocated by the caller with a size of InputDataSizeInBytes. This struct is enumerable as the D3D12_VIDEO_EXTENSION_COMMAND_PARAMETER_STAGE_CAPS_INPUT parameter stage.

InputDataSizeInBytes

The byte size of the input data allocation.

pOutputData

Output data for the capability query allocated by the caller with a size of OutputDataSizeInBytes. This struct is enumerable as the D3D12_VIDEO_EXTENSION_COMMAND_PARAMETER_STAGE_CAPS_OUTPUT parameter stage.

OutputDataSizeInBytes

The byte size of the output data allocation.
