IVPConfig interface
The IVPConfig interface must be implemented by any filter that wraps a hardware decoder with a video port. This enables the Overlay Mixer, through its IVPNotify interface, to set and retrieve configuration information on the video port regarding the video memory on the display adapter. This interface derives from IVPBaseConfig.
Applications never use this interface.
Methods
The IVPConfig interface has these methods.

| IVPConfig::IsVPDecimationAllowed | The IsVPDecimationAllowed method, given the context, retrieves whether scaling at the video port is possible. |
| IVPConfig::SetScalingFactors | The SetScalingFactors method sets the factors by which the decoder should scale the video stream. |
