IFileSourceFilter Interface

Windows Mobile 6.5
A version of this page is also available for
4/8/2010

This interface is exposed by source filters to set the file name and media type of the media file that they are to render. It is an abbreviated version of the COM IPersistFile interface.

If the file has a type that can be determined by the algorithm described in "Registering a Custom File Type," the recommended file source filter CLSID is used when the filter graph manager attempts to render the filter graph.

If a filter needs the name of a file to open, it should expose this interface to allow an application to set the file name.

There is no base class implementation of this interface.

An application that inserts file source filters directly must query for this interface and set the file name. Normally, the filter graph manager uses this interface when an application calls IGraphBuilder::RenderFile.

The following table shows the methods that appear in the Vtable beneath the standard COM methods inherited from IUnknown.
