IVMRFilterConfig9::SetImageCompositor method (vmr9.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The SetImageCompositor method installs an application-provided image compositor object.

Syntax

HRESULT SetImageCompositor(
  [in] IVMRImageCompositor9 *lpVMRImgCompositor
);

Parameters

[in] lpVMRImgCompositor

Pointer to the image compositor object provided by the application.

Return value

The method returns an HRESULT. Possible values include those in the following table.

Remarks

Use this method to replace the VMR's default compositor with a custom compositor provided by the application. The image compositor is a sub-component of the mixer. The mixer must be loaded, through a call to IVMRFilterConfig9::SetNumberOfStreams,

before the compositor can be specified. The VMR manages all reference counting on the IVMRImageCompositor9 interface.
