IGraphBuilder inherits from the IFilterGraph interface. IFilterGraph provides basic operations, such as adding a filter to the graph or connecting two pins. IGraphBuilder adds further methods that construct graphs from partial information. For example, the IGraphBuilder::RenderFile method builds a graph for file playback, given the name of the file. The IGraphBuilder::Render method renders data from an output pin by connecting new filters to the pin.
