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.
