- DirectShow Sample -- Mapper
- ---------------------------
-
- This sample demonstrates using the IFilterMapper2::EnumMatchingFilters method
- to locate filters in the registry. The application's user interface contains controls
- that match the parameters of the EnumMatchingFilters method, such as minimum merit value,
- pin categories, and media types.
-
- Select the search options that you want, then click the Search button to enumerate
- the filters that match those options. The list box will display the results of your
- query, including the filter's Friendly Name, Filter merit, and the filename of the
- server which contains it. Tooltips are provided to help explain the user interface
- elements.
-
- Although the EnumMatchingFilters method allows you to specify the number of
- media type/subtype pairs to use in the query, the Mapper application only provides
- two sets of list boxes for input and output types. If the first media type is specified
- as a "Don't Care" condition, then the secondary media type/subtype listboxes will
- be disabled to prevent confusion. By default, the search elements are configured
- to display all filters with a merit value of Normal or higher.
