Camera model
Logitech Webcam C615
What is the problem?
I am using a Logitech Webcam C615 webcam for my Raspberry pi Octoprint setup. For some reason it no longer works unless I login via SSH, and enter the following commands. When I close the SSH session, the camera stops working.
What did you already try to solve it?
sudo systemctl restart webcamd
sudo systemctl enable webcamd
# Camera Settings, cron job usually sets these properly on startup, but it's hit or miss.
sudo v4l2-ctl --set-ctrl=focus_auto=0 && sudo v4l2-ctl --set-ctrl=focus_absolute=120
I also set these commands as buttons in the Octoprint UI via the config.yaml file to easily restart the camera and set parameters without SSH. Worked for a while when needed, and usually only the refocus command was ever necessary.
system:
actions:
- action: refocuscamera
command: sudo v4l2-ctl --set-ctrl=focus_auto=0 && sudo v4l2-ctl --set-ctrl=focus_absolute=120
name: Refous Camera
- action: divider
- action: restartcamera
command: sudo systemctl restart webcamd && sudo systemctl enable webcamd
confirm: You are about to restart your webcam. This will break timelapse!
name: Restart Camera
However it now stops working when I logout of ssh even after issuing those commands. To get it started I have to unplug and replug in the camera, login again and type the same commands again. I set my computer to keep the connection alive indefinitely, but that doesn't solve the core problem. I also set the user pi to no longer need 'sudo' in the 'sudoers' file. Thanks for any help you can give me!
