View Full Version : Switching video streams to one Renderer

February 12, 2008, 13:33:39

I want to switch two or more video streams to one video renderer. I don't want to get more than one video window in my application. So I need to switch between the video streams to show only one at a time.
Does anyone have a solution?

Hallo Michael,

Yes, if you use the Video Mixing Renderer (VMR) in mixing mode in combination with our VMR wrapper ActiveX Control, then you can choose the visible video by setting the alpha values for the corresponding input pins. In the Workbench, right click the renderer before connecting it and choose "Set Mixer Mode" in order to enable mixing mode for x streams.

In the MS DirectShow SDK binaries folder, there is a file called proppage.dll, which provides some additional VMR property pages. If you register the DLL using RegSvr32, then you'll see the new dialogs the next time you open the Workbench. If you don't have the SDK installed or if you can't find the file, please contact support@montivision.com for further support.

Best Regards,
