IMFExtendedCameraController interface (mfidl.h)

Allows apps to retrieve an instance of IMFExtendedCameraControl, which is used to configure a capture device's extended properties.

Inheritance

The IMFExtendedCameraController interface inherits from the IUnknown interface.

Methods

The IMFExtendedCameraController interface has these methods.

Remarks

The IMFExtendedCameraController interface can be obtained through the IMFMediaSource that represents the video capture device and its IMFGetService implementation. In this case, guidService parameter of the IMFGetService::GetService function must be GUID_NULL, please see following code snippet.

HRESULT GetExtendedCameraController(_In_ IMFMediaSource* pCameraSource)
{
 wil::com_ptr_nothrow<IMFExtendedCameraController> spExtCameraController;
 wil::com_ptr_nothrow<IMFGetService> spGetService;

 RETURN_IF_FAILED(pCameraSource->QueryInterface(IID_PPV_ARGS(&spGetService)));
 RETURN_IF_FAILED(spGetService->GetService(GUID_NULL, IID_PPV_ARGS(&spExtCameraController)));

 // Use the IMFExtendedCameraController to check for support of a specific IMFExtendedCameraControl using GetExtendedCameraControl()

 return S_OK;
}
