The IMDServiceProvider interface is the initial interface that Windows Media Device Manager uses to connect to your service provider. Using this interface, Windows Media Device Manager can enumerate and communicate with the all media devices supported by a particular service provider. The IMDServiceProvider2 interface can be implemented to create devices by using the device path.

In addition to the methods inherited from IUnknown, the IMDServiceProvider interface exposes the following methods.

Method Description
EnumDevices Enumerates the installed physical or software devices that are currently attached and are known by the service provider.
GetDeviceCount Retrieves the number of media devices that are currently attached and are known by the service provider.
