Watermark Category Types

[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 It has been superseded by Source Reader and Sink Writer.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.]

You can use the DMO enumeration function, DMOEnum, to get information about the watermarking DMOs that are installed on a computer. The Windows Media Format SDK defines GUIDs that identify the watermarking DMO categories. For more information about DMOEnum, see the DirectShow documentation on MSDN.

The following table lists the identifiers for watermarking categories.
