IWMPGraphCreation interface (wmpservices.h)
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IWMPGraphCreation interface provides methods that Windows Media Player calls to enable you to manage the DirectShow filter graph. It can be implemented by an application that embeds the Windows Media Player control.
The Windows Media Player control retrieves a pointer to this interface by calling IServiceProvider::QueryService. When you implement IWMPGraphCreation, you must also implement IServiceProvider and return the correct pointer when QueryService is called with IID_IWMPGraphCreation as the value for the second parameter.
This interface is not supported when remoting the Windows Media Player control.
