OctoPrint external USB camera feed goes away - fix included
I use an external, USB connected webcam to monitor a Prusa Mini via Octoprint. Every once in a while the video feed in Octoprint goes away. Rather than have to reboot the RPi, the following command always fixes the issue even when in the middle of a print:
sudo service webcamd restart
You do need terminal access via ssh, VNC, local keyboard and monitor, etc.
Currently running v1.5.3 Octoprint on a RPi 3B+

I would recommend to check this page:

Some webcameras connected via USB may be problematic, like high power-output or peaks, bad drivers etc...
I have one Microsoft camera, that had power-peaks, that even raspberry deemed them once a while as faulty. Reboot was necessary

I will give this a try tonight. I have one that is a little finicky.
