The IVMRWindowlessControl9 interface controls how the Video Mixing Renderer Filter 9 (VMR-9) renders a video stream within a container window. Applications must first put the VMR-9 into windowless mode before using the methods on this interface.
In addition to the methods inherited from IUnknown, the IVMRWindowlessControl9 interface exposes the following methods.
|DisplayModeChanged||Informs the VMR that a WM_DISPLAYCHANGE message has been received by the application.|
|GetAspectRatioMode||Retrieves the current aspect ratio display mode.|
|GetBorderColor||Retrieves the current border color used by the VMR.|
|GetCurrentImage||Retrieves a copy of the current image being displayed by the VMR.|
|GetMaxIdealVideoSize||Retrieves the maximum video size that the VMR can display without incurring significant performance or image quality degradation.|
|GetMinIdealVideoSize||Retrieves the minimum video size that the VMR can display without incurring significant performance or image quality degradation.|
|GetNativeVideoSize||Retrieves the un-stretched video size and aspect ratio of the video.|
|GetVideoPosition||Retrieves the current source and destination rectangles used to display the video.|
|RepaintVideo||Repaints the current video frame.|
|SetAspectRatioMode||Sets the current aspect ratio display mode.|
|SetBorderColor||Sets the border color to be used by the VMR.|
|SetVideoClippingWindow||Specifies the container window that video should be clipped to.|
