SIZE_T Pfnd3d12ddiCalcprivatevideodecoderheapsize0072(
       D3D12DDI_HDEVICE hDrvDevice,
  [in] const D3D12DDIARG_CREATE_VIDEO_DECODER_HEAP_0072 *pArgs
)
{...}

Parameters

hDrvDevice

Handle to the hardware device being processed.

[in] pArgs

Pointer to a D3D12DDIARG_CREATE_VIDEO_DECODER_HEAP_0072 structure with arguments used by this callback function.

Return value
