IVPNotify2 Interface
The IVPNotify2 interface inherits from IVPNotify and is implemented by the Overlay Mixer filter. This interface enables the Overlay Mixer to communicate with a video port (on a hardware device such as a decoder) that implements IVPConfig.
Applications should never use this interface.
In addition to the methods inherited from IVPNotify, the IVPNotify2 interface exposes the following methods.
| Method | Description |
| SetVPSyncMaster | Sets whether the video port controls vertical synchronization of the VGA. |
| GetVPSyncMaster | Checks whether the video port controls the synchronization of the VGA. |
