DirectX Renderer using webcam in multiple monitors

I’m trying to use 2 DirectX renderers simultaniously for doing vj visuals, one is intended to be the output while the other works for me as a preview window.

My problem is that when I try to display a camera or video on both renderers at the same time only get one of them to display de video feed when I use two monitors. If I drag both windows to the same monitor they both show the video but on the extended desktop I only one is shown.

Has this happened to any of you guys? Any successful workaround?

I have not been able to force my nvidia card to set DX9 rendering to true on both devices.

Any suggestions would be really appreciated.


ja, this is a known problem. but according to cross-process-texture-sharing-depth-rendering try starting vvvv with /dx9ex as a commandline argument and it shall do.

Hell Yeah!!! That was it mate. I thank u so much
Anyway I could only get it to work with latest alpha, but it’s ok I guess
