IAMMediaContent Interface

The IAMMediaContent interface provides methods for retrieving metadata from a stream. Applications can use this interface to retrieve information encoded into a stream, such as the author, title, and copyright. This interface is typically exposed by parser filters, such as the AVI Splitter filter and the MPEG-1 Stream Splitter filter.

Depending on the stream type, a filter might support a subset of the methods on this interface. For example, the AVI Splitter retrieves the copyright, author name, and title from INFO chunks in the AVI file. The remaining methods return E_NOTIMPL.

Note   Microsoft® Windows Media™ Player does not use this interface to display metadata.
