HEllo there.

I am tasked with hosting a multicam livestream at a large LAN-event soon. During our multicam we want to be able to cut to random players playing their game.
We worked everything out and got everything to work except for the vMIX Desktop Capture Tool to capture FULLSCREEN VIDEOGAMES.
The tool, however, is able to record video games being played in WINDOWED mode but this is not an option for us.

We also tried getting a signal from VLC, but VLC is also not able to record FULLSCREEN videogames.
At last we tried OPEN BROADCASTER SOFTWARE, but this requires an RTMP server which non of the staff has knowledge about.

Is their any way we can easly record FULLSCREEN GAMES with a simple program like the official vMIX Desktop Capture Software to our vMIX program?

Thanks in advance.
