IFilterMapper2 interface
Applies to: desktop apps only
Registers and unregisters filters, and locates filters in the registry. The Filter Mapper helper object implements this interface.
Filters use this interface to register and unregister themselves. When the filter graph manager builds a filter graph, it uses this interface to look up filters and determine their characteristics. Applications can also use this interface to look up filters. For more information, see Using the Filter Mapper and How to Register DirectShow Filters.
