PFND3D12DDI_CALCPRIVATEVIDEOPROCESSORSIZE_0072 Pfnd3d12ddiCalcprivatevideoprocessorsize0072;

SIZE_T Pfnd3d12ddiCalcprivatevideoprocessorsize0072(
  D3D12DDI_HDEVICE hDrvDevice,
  const D3D12DDIARG_CREATE_VIDEO_PROCESSOR_0072 *pArgs
)
{...}

Parameters

hDrvDevice

A handle to the display device (graphics context).

pArgs

Pointer to a D3D12DDIARG_CREATE_VIDEO_PROCESSOR_0072 structure with arguments for this callback to use.
