Setting the resolution of a webcam

Hi,

I would like to us a webcam for a projection on a screen.

If I choose DirectShow I am able to set the camera settings like exposure, manual focus etc. . But if I want to to change the resolution I get an error that it’s not supported.
Media Foundation lets me choose the resolution (strangely since I upgraded to Touch 099 I can not choose 1080 because the screen turns black. But it works with 720). But I can’t control the camera settings. This is a problem because the image is constantly changing in exposure and focus.

The webcam is called “Microsoft LifeCam Studio HD”. A link to it is “https://www.microsoft.com/accessories/de-de/products/webcams/lifecam-studio/q2f-00015

It would be awesome if you would know a workaround to this.
