OctoPi/OctoPrint Change Webcam Resolution

---

You can change the webcam’s resolution via the cmd line on OctoPrint by

sudo vi /boot/octopi.txt

And adding this to the file:

camera="usb"
camera_usb_options="-r 1280x720 -f 10"

You can get a list of the supported resolution via (may need v4l-utils installed):

v4l2-ctl -d /dev/video0 --list-formats-ext 

and then reboot the pi
