The Microsoft® Windows Media™ Format Software Development Kit (SDK) is designed to accomplish three major tasks: writing Windows Media™ files based on supplied uncompressed media data, editing the metadata in a Windows Media file, and reading Windows Media files and supplying the uncompressed data as output. There are three main objects that accomplish these tasks, whose interfaces are IWMWriter, IWMMetadataEditor, and IWMReader. There are, however, many other interfaces that provide advanced reading and writing capabilities, handle callbacks, configure profiles, and so on.
The following sections explain in detail the steps required to write, read, and edit Windows Media files by using this SDK, the available formats, and the interfaces, functions, and methods.
