Insufficient permissions on /dev/video0

nebnes opened this issue 10 years ago · comments

Hi !

When I run the example I have this "Insufficient permissions on /dev/video0 -- does the app have the CAMERA permission?" in the console.

I have check the permission in the manifest and I have also check the permission in adb:
"crw-rw---- system camera 81, 1 2014-09-11 21:15 video0"

thanks in advance

Your permissions are not correct. The user needs to be media and the group needs to be camera (please check this is the manual). So 'chown media /dev/video0' to fix it

From README:
"If the file is at least 0660, owned by the media user with the group camera, you're good to go.

Add the CAMERA permissions to your app's manifest:"
