Got an issue getting a webcam to work with OctoPi, or some timelapse related issues? This is the right place. Make sure to include all available information on the type of webcam you are struggling to get to work, and also include /var/log/webcamd.log from the log files.
For Octolapse please get in touch in the #plugins category instead!
Just a comment: On OctoPrint release prior to 1.10 my Rasberry Pi camera worked fine - after new release not working and many users have the same problem.
Suggestion: Would it be possible to have maybe 3 camera options and user can select either one?
Option 1: Onboard Rasberry Pi camera plugged into camera slot on Rasberry Pi
Option 2: USB external webcam plugged into Rasberry PI USB port
Option 3: Wifi camera connected to the internet
