Comments
For more information on the support media types, refer to section of Formats, Media Types and Media Subtypes.
If IltmmWMProfile::CreateNewStream succeeds, the caller must free the retrieved interface by calling its Release method.
Please note that creating a new stream does not automatically add it to the profile. The new stream must be created using IltmmWMProfile::CreateNewStream, and then configured using the IltmmWMStreamConfig interface. The configured stream must then be added to the profile using IltmmWMProfile::AddStream.
For more information, refer to the Microsoft documentation for IWMProfile::CreateNewStream at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmform11/htm/iwmprofilecreatenewstream.asp.
