IWMHeaderInfo2::GetCodecInfoCount method (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 It has been superseded by Source Reader and Sink Writer.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 GetCodecInfoCount method retrieves the number of codecs for which information is available. The codecs counted are those that were used to encode the streams of the file loaded in the metadata editor, reader, or synchronous reader object to which the IWMHeaderInfo2 interface belongs.
