IWMReaderAdvanced3 interface (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The IWMReaderAdvanced3 interface provides additional functionality to the reader object. It contains methods that enhance the ability to playback a file.

IWMReaderAdvanced3 exists for each instance of the reader objects created with the WMCreateReader function.
