The script is fresh downloaded from github, only I edited the webcam device location ( /dev/video0 )

[wargio]

are you sure that's the correct char dev? check with another app like cheese or vlc. if they have problems with that, well, it's a driver problem, or is not supported by video4linux2

[adaliszk]

char dev? I checked my webcam with cheese and it's worked.

[wargio]

char device. check if cheese is actually using /dev/video0, because that's weird.

[adaliszk]

Cheese using /dev/video0 and the camera is working fine.

try to change the permissions: chmod 775 /dev/video0
