IWMProfile::AddStream method

The AddStream method adds a stream to the profile by copying the stream configuration details into the profile.

Use AddStream only to include a stream that is new to the profile. New streams can be created by calling IWMProfile::CreateNewStream, but will not be added to the profile until AddStream is called.

If you edit an existing stream using IWMProfile::GetStream or IWMProfile::GetStreamByNumber, you should not call AddStream to include the changes. To include changes made to an existing stream, call IWMProfile::ReconfigStream.

Syntax

HRESULT AddStream(
  IWMStreamConfig *pConfig
);

Parameters

pConfig

Pointer to the IWMStreamConfig interface of the stream configuration object to be added to the profile. The stream must be configured by using the methods of the IWMStreamConfig interface before this method is used to add the stream to the profile.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
The method succeeded.
E_INVALIDARG
The pConfig parameter is NULL.
E_OUTOFMEMORY
