IFilterGraph interface (strmif.h)

The IFilterGraph interface provides methods for building a filter graph. An application can use it to add filters to the graph, connect or disconnect filters, remove filters, and perform other basic operations. However, the IGraphBuilder interface inherits from this interface and provides additional methods that are more sophisticated. Therefore, applications should use IGraphBuilder rather than using IFilterGraph directly.

The filter graph manager implements this interface.

Inheritance

The IFilterGraph interface inherits from the IUnknown interface. IFilterGraph also has these types of members:

Methods

The IFilterGraph interface has these methods.

IFilterGraph::AddFilter The AddFilter method adds a filter to the graph.
IFilterGraph::ConnectDirect The ConnectDirect method connects the two pins directly (without intervening filters).
IFilterGraph::Disconnect The Disconnect method disconnects this pin.
IFilterGraph::EnumFilters The EnumFilters method provides an enumerator for all filters in the graph.
IFilterGraph::FindFilterByName The FindFilterByName method finds a filter that was added to the filter graph with a specific name.
IFilterGraph::Reconnect The Reconnect method disconnects a pin and then reconnects it to the same pin.
IFilterGraph::RemoveFilter The RemoveFilter method removes a filter from the graph.
IFilterGraph::SetDefaultSyncSource The SetDefaultSyncSource method sets the reference clock to the default clock.
