live streaming with two camera

Hello,

I have a blackmagic ultrastudio4k. I would like to live sreaming on facebook with two camera and two xlr sound plug with OBS.
Is it possible to manage with all this stuf.
OBS seem to not capture the second camera.
The two cameras are plug with SDI cable.

Thanks

Xavier

I see only one camera on the display of blackmagic ultrastudio 4K. How can I manage to see the second camera?

Thanks

Hello Xavier. The Ultrastudio 4K is only a single input device. The two SDI inputs would be used for single signals that require two connections such as 444 or Stereoscopic images.
