| Microsoft DirectX 8.1 (C++) |
The get_DefaultPreferredComponentTypes method returns an enumeration of the preferred component types, which specify parameters such as the preferred audio stream.
Syntax
HRESULT get_DefaultPreferredComponentTypes(
IComponentTypes** ppComponentTypes
);
Parameters
ppComponentTypes
[out] Address of an IComponentTypes interface pointer that receives the returned collection.
Return Values
Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.
Remarks
A "component" in this context means a stream within the program. An example of a "preferred component" would be an audio stream in English. When multiple components or streams are available, the Tuner will always attempt to play the preferred ones first.
