Question / Help Game capture and Cam not working together?

[Haikuna]

I've literally been looking everywhere for a solution to this, and I still haven't been able to find a thread which is like it. So I'm trying to stream League of Legends, which my computer is doing fine without no problems, images works too when in game. But when I try to add my cam, it just goes black. If I then tab out the cam will start working. How can I work around this?
Bonus Question: Window capture doesn't seem to be working either, any solutions to this aswell?

Thanks for your time, it really means a lot to me.

Are you adding your camera as a video capture device, or are you trying to use window capture on a different program that shows the webcam image? Make sure you use the video capture device method.

Bonus Answer: Window capture won't work if you're running the game in full screen, since other windows aren't rendered during that time. You'll need to switch the game to borderless windowed mode if you want to use window capture on other things (and/or the game itself) while the game runs.

I used the Video Capture Device, and it still only shows up when I'm tabbed out of the game.
Thanks for the other answer though, hope you can help with the main one aswell.
**EDIT**
I've once seen a thread which said that I should try adding it to global sources, and then add it to my scene, I did this and it still has not fixed the problem.
