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 .
