I'm currently running Octoprint 1.6.1 on a Raspberry Pi 3B+
Like many people, I often have problems with my webcam (I have a mystery off brand webcam) that often crashes for no apparent reason.
I do manage to fix it every time by opening Kitty, SSHing into Octoprint and sending:
sudo systemctl restart webcamd
This works great but it's really annoying.
Would it be possible in the webcam window, when you get the information asking you to check that the webcam is connected on the correct path for the streaming device, to get a link to reboot the webcam daemon?
I know it's not an elegant solution but it does have the advantage of being simple.
