Webcam focus adjustment

**I recently picked up the webcam and the cam itself works great. The only problem is that it is a bit out of focus so I need to adjust it. **

**I have tried running sudo v412-ctl --set-ctrl=focus_auto=0 but get the error: "unknown control 'focus_auto' **

Additional information about your setup (OctoPrint version, OctoPi version, ...)

run v4l2-ctl -l to get a list of all available parameters (or v4l2-ctl -L for a list with expanded menus)

Sorry then there's unfortunately no way to change the focus with v4l2

Is there another method other than v412?

There are/were some uvc tools which are capable of doing similar things as v4l2 like setting the focus but I got no autofocus cam to test them so you have to test them yourself

that's what I found on google - there might be more or better tools
