IVMRFilterConfig9::SetImageCompositor

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

Syntax

HRESULT SetImageCompositor(
  IVMRImageCompositor9*  lpVMRImgCompositor
);

Parameters

lpVMRImgCompositor

[in]  Pointer to the image compositor object provided by the application.

Return Values

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

Value Description
S_OK The method succeeded.
VFW_E_WRONG_STATE The mixer is not currently loaded.

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.

Requirements

Include D3d9.h, Vmr9.h.
