IVPBaseConfig is implemented on a filter that wraps a hardware device such as a decoder, if that device has a video port to the graphics adapter. This interface allows the video port to communicate with the Overlay Mixer filter regarding configuration information. The IVPConfig interface derives from this interface. See also IVPBaseNotify and IVPNotify.
Applications never use this interface.
Requirements
Requires Dvp.h, Vptype.h, Vpconfig.h.
In addition to the methods inherited from IUnknown, the IVPBaseConfig interface exposes the following methods.
| Method | Description |
| GetConnectInfo | Retrieves connection information structures. |
| SetConnectInfo | Sets the index for the current video port connection information. |
| GetVPDataInfo | Retrieves the current video port data information. |
| GetMaxPixelRate | Retrieves the maximum pixels per second rate for a given width and height. |
| InformVPInputFormats | Informs the device what video formats the video port supports. |
| GetVideoFormats | Retrieves the video formats the decoder supports. |
| SetVideoFormat | Sets the format that the video will use. |
| SetInvertPolarity | Reverses the current polarity the decoder uses. |
| GetOverlaySurface | Determines whether the overlay mixer should use the driver's overlay surface and if so retrieves a pointer to the surface. |
| SetDirectDrawKernelHandle | Sets the Microsoft� DirectDraw� kernel handle for the decoder's minidriver to use. |
| SetVideoPortID | Sets the port ID that the video will use. |
| SetDDSurfaceKernelHandle | Sets the kernel handle that the DirectDraw surface will use. |
| SetSurfaceParameters | Tells the capture driver about the surface created on its behalf by the Overlay Mixer or VBI surface filter. |
