IWMMediaProps::GetType 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 It has been superseded by Source Reader and Sink Writer.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 GetType method retrieves the major type of the media in the stream, input, or output described by the object to which the current IWMMediaProps interface belongs.
Syntax
HRESULT GetType(
[out] GUID *pguidType
);
Parameters
[out] pguidType
Pointer to a GUID specifying the media type.
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 pguidType parameter is NULL. |
Remarks
These media types are used by the writer, reader, and profile objects to identify the properties of a media stream that are specific to the media type.
GetType is provided for convenience; it returns the same value as the majortype member of WM_MEDIA_TYPE.
