Syntax


HRESULT GetVideoService(
  [in]   HANDLE hDevice,
  [in]   REFIID riid,
  [out]  void **ppService
);

Parameters

hDevice [in]

A handle to the Direct3D device. To get the device handle, call IMFDXGIDeviceManager::OpenDeviceHandle.

riid [in]

The interface identifier (IID) of the requested interface. The Direct3D device supports the following interfaces:

  • ID3D11Device. To get a pointer to the Direct3D11 device, use IID_ID3D11Device as the riid.
  • ID3D11VideoDevice. To get a pointer to the Direct3D11 video device, use IID_ID3D11VideoDevice as the riid.
ppService [out]

Return codeDescription
S_OK

Success.

E_HANDLE

The specified handle is not a Direct3D device handle.

MF_E_DXGI_DEVICE_NOT_INITIALIZED

The DXGI Device Manager was not initialized. The owner of the device must call IMFDXGIDeviceManager::ResetDevice.

MF_E_DXGI_NEW_VIDEO_DEVICE

The device handle is invalid.

E_NOINTERFACE

If a ID3D11VideoDevice is specified and the D3D device created is using the reference rasterizer or WARP. Or it is a hardware device and you are using the Microsoft Basic Display Adapter.

 

Remarks

If the method returns MF_E_DXGI_NEW_VIDEO_DEVICE, call IMFDXGIDeviceManager::CloseDeviceHandle to close the handle and then call OpenDeviceHandle again to get a new handle. The IMFDXGIDeviceManager::ResetDevice method invalidates all open device handles.
