Using System Profiles
[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 It has been superseded by Source Reader and Sink Writer.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 system profiles included with the Windows Media Format SDK were designed to cover the basic needs of digital media content comprised of audio and video. Because of the great variety of features now available, and the related increase in possible digital media scenarios, system profiles have been deemphasized. The most recent set of system profiles make use of the version 8 Windows Media codecs which were released with Windows XP. Despite not supporting the latest version of the codecs, the system profiles make an excellent starting point for creating profiles to suit your needs.
