I got a webcam recently and I really need to change the settings, the exposure is blown out and the saturation is halfway to black and white, nowhere near the true colors. I SSH-d into my Raspberry pi3B and installed uvcdynctrl and when i use the "uvcdynctrl -d /dev/video0 -c" command i can indeed see the list of all the settings that are available but I cant use any of them. above the list there is a block of error text that all starts with "[libwebcam]Unknown V4L2 user ID encountered" , "[libwebcam]Unknown V4L2 control type encountered" OR "[libwebcam]Unknown V4L2 MPEG control ID encountered"
I'm very new to using Octoprint, only been doing for maybe 4 months but have never tried to adjust my webcam before. I'm wondering if there's a command I need to run that I didn't see.
