打造真彩色传奇

请问一下你那魔法特效是怎么做的
是加入AVI文件的方法么
有点问题想请教你，
那能看一下下面的代码：
procedure TAsphyreDevice.CreateDirectshow;
var
filterConfig:IVMRFilterConfig9;
VMRWindowlessControl:IVMRWindowlessControl;
begin
try
  FilterGraph:=CreateComobject(CLSID_FilterGraph) as IGraphBuilder;//创建FilterGraph
  VideoRender:=createcomobject(CLSID_VideoMixingRenderer9) as IBaseFilter;//创建VideoMixingRenderer9
  Filtergraph.AddFilter(VideoRender,'VideoRender');//将VideoMixingRenderer9加入到Filtergraph中
   VideoRender.QueryInterface(IID_IVMRFilterConfig9,FilterConfig);//获得IVMRFILTERCONFIG9接口
   FilterConfig.SetRenderingMode(VMR9Mode_Windowless);//设置窗口模式为WINDOWLESS
   VideoRender.QueryInterface(IID_IVMRWindowLessControl,VMRWindowlessControl);//得不到IVMRWINDOWLESSCONTROL接口
   if MediaPlayWindowHandle=0 THEN
   begin
   Messagebox(0,'Clip Window Can''t be 0','出错',MB_ICONERROR or MB_OK);
   freedirectshow;
   exit;
   end;


  VMRWindowlessControl.SetVideoClippingWindow(MediaPlayWindowHandle);  //有问题！没有能得到IVMRWindowlessControl

finally
VMRWindowlessControl:=NIL;
FilterConfig:=nil;

end;
end;
