Troubleshooting • Re: getting OSError: libbcm_host.so: cannot open shared object file: No such file or directory error while accessing cam

However:

Code:

Wild guess time. You've created an additional user that wasn't renamed from the default pi user. Your new user needs to be added to the video group for the camera to work without sudo/su. The default user is also a member of various other groups as well so add those as needed.
