如何在單個流中合併多個實時（視頻）流？所以輸出將是單個視頻中的多個（分割）視頻？

我對流式傳輸很新穎。我的要求是將多個視頻/流合併到單個視頻中。因此，輸出將是單個視頻在單個播放器中同時顯示多個視頻（如安全攝像頭視頻）。如何在單個流中合併多個實時（視頻）流？所以輸出將是單個視頻中的多個（分割）視頻？

這裏是我的示例代碼---

IGraphBuilder oFilterGraph = (IGraphBuilder)new FilterGraph(); 
VideoMixingRenderer9 oVideoMixingRenderer = new VideoMixingRenderer9(); 
oFilterGraph.AddFilter((IBaseFilter)oVideoMixingRenderer, "Video"); 

IVMRFilterConfig9 oVMRFilterConfig = (IVMRFilterConfig9)oVideoMixingRenderer; 
oVMRFilterConfig.SetRenderingMode(VMR9Mode.Windowed); 
oVMRFilterConfig.SetNumberOfStreams(2); 
oVMRFilterConfig.SetRenderingPrefs(VMR9RenderPrefs.None);    

IVMRMixerControl9 oIVMRMixerControl = (IVMRMixerControl9)oVideoMixingRenderer; 

NormalizedRect oNormalizedRect = new NormalizedRect(); 
oNormalizedRect.left = 0.0F; 
oNormalizedRect.top = 0.0F; 
oNormalizedRect.bottom = 0.5F; 
oNormalizedRect.right = 0.5F; 
NormalizedRect oNormalizedRect1 = new NormalizedRect(); 
oNormalizedRect.left = 0.5F; 
oNormalizedRect.top = 0.5F; 
oNormalizedRect.bottom = 1; 
oNormalizedRect.right = 1; 

int iStreamId1 = oFilterGraph.RenderFile("c:\\file1.wmv", string.Empty); 
int iStreamId2 = oFilterGraph.RenderFile("c:\\file2.wmv", string.Empty); 
oIVMRMixerControl.SetOutputRect(0, ref oNormalizedRect); 
oIVMRMixerControl.SetOutputRect(1, ref oNormalizedRect1);   
oIVMRMixerControl.SetAlpha(0, 1); 
oIVMRMixerControl.SetAlpha(1, 1); 

IMediaControl oMediaControl = (IMediaControl)oFilterGraph; 
oMediaControl.Run();

我試着用代碼，但未能成功。它只顯示一個視頻在控制&不顯示另一個。
