IWMProfile::CreateNewStream method (wmsdkidl.h)
[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 It has been superseded by Source Reader and Sink Writer.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 CreateNewStream method creates a stream configuration object. You can use a stream configuration object to define the characteristics of a media stream.
Syntax
HRESULT CreateNewStream(
[in] REFGUID guidStreamType,
[out] IWMStreamConfig **ppConfig
);
Parameters
[in] guidStreamType
GUID object specifying the major media type for the stream to be created (for example, WMMEDIATYPE_Video). The supported major types are listed in Media Types.
[out] ppConfig
Pointer to a pointer to the IWMStreamConfig interface of the created stream configuration object.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The ppConfig parameter is NULL. |
|
There is not enough available memory. |
Remarks
It is not possible to have a stream configuration object other than as an element of a profile. After the stream has been configured, this object must be added to the profile by using the AddStream method.
When CreateNewStream is called, a valid stream number is specified for the new stream. Stream numbers are in the range of 1 through 63.
