This topic applies to Windows XP or later.

The IMSVidVideoRenderer interface represents a video renderer device. The MSVidVideoRenderer object exposes this interface.

This interface provides access to the Video Mixing Renderer (VMR) filter.

Methods

The IMSVidVideoRenderer interface inherits from IMSVidOutputDevice.

In addition, IMSVidVideoRenderer defines the following methods.

Method	Description
Capture	Captures the video frame that is currently being rendered by the VMR.
get__CustomCompositor	Retrieves the VMR's current image compositor.
get__CustomCompositorClass	Retrieves the class identifier (CLSID) of the VMR's current image compositor, as a GUID
get__MixerBitmap	Retrieves the VMR's IVMRMixerBitmap interface, which controls how the VMR mixes a static bitmap
get_AvailableSourceRect	Retrieves the size of the native video.
get_ClippedSourceRect	Retrieves the clipping rectangle on the video source.
get_CustomCompositorClass	Retrieves the CLSID of the VMR's current image compositor, as a BSTR.
get_DecimateInput	Indicates whether the VMR will decimate the video (that is, reduce the native video size) before processing it.
get_FramesPerSecond	Retrieves the current frame rate.
get_MaxVidRect	Retrieves the maximum ideal size of the video rectangle.
get_MinVidRect	Retrieves the minimum ideal size of the video rectangle.
get_MixerBitmap	Retrieves the static bitmap image, as an IPictureDisp type.
get_MixerBitmapOpacity	Retrieves the opacity of the static bitmap image.
get_MixerBitmapPositionRect	Retrieves the position of the static bitmap image, relative to the video window.
get_OverScan	Retrieves the amount of clipping to perform on all sides of the video frame, in order to cut off random video noise.
get_SourceSize	Retrieves the type of clipping to apply to the video rectangle, if any.
get_UsingOverlay	Queries whether the VMR is using the hardware overlay.
put__CustomCompositor	Specifies a custom image compositor for the VMR to use.
put__CustomCompositorClass	Specifies the CLSID of a custom image compositor, as a GUID.
put__MixerBitmap	Specifies the static bitmap image.
put_ClippedSourceRect	Specifies the clipping rectangle on the video source.
put_CustomCompositorClass	Specifies the CLSID of a custom image compositor, as a BSTR.
put_DecimateInput	Specifies whether the VMR will decimate the video (that is, reduce the native video size) before processing it.
put_MixerBitmap	Specifies the static bitmap image, as an IPictureDisp type.
put_MixerBitmapOpacity	Specifies the opacity of the static bitmap image.
put_MixerBitmapPositionRect	Specifies the position of the static bitmap image, relative to the video window.
put_OverScan	Specifies the amount of clipping to perform on all sides of the video frame, in order to cut off random video noise.
put_SourceSize	Specifies the type of clipping to apply to the video rectangle, if any.
put_UsingOverlay	Specifies whether the VMR will use the hardware overlay.
SetupMixerBitmap	Configures the VMR to display an alpha-blended bitmap on top of the video.
