IFilterGraph2 Interface

The IFilterGraph2 interface extends the IFilterGraph and IGraphBuilder interfaces, which contain methods for building filter graphs.

The filter graph manager implements this interface. Applications can use it when building graphs, to take advantage of the additional methods it provides.

IFilterGraph2 adds two methods to IFilterGraph and IGraphBuilder.

• The IFilterGraph2::AddSourceFilterForMoniker method creates a source filter based on a moniker, and adds it to the graph.
• The IFilterGraph2::ReconnectEx method improves the IFilterGraph::Reconnect method by specifying a media type for the reconnection.

In addition to the methods inherited from IUnknown, IFilterGraph and IGraphBuilder, the IFilterGraph2 interface exposes the following methods.
