Standard method
import pygame.camera
pygame.camera.init()
camera = pygame.camera.Camera('/dev/video0')
It will not work
from pygame.camera import init as camera_init
from pygame.camera import Camera
camera_init()
camera = Camera('/dev/video0')
because Camera has oryginal class, not replaced by init()
It will work
from pygame.camera import init as camera_init
camera_init()
from pygame.camera import Camera
camera = Camera('/dev/video0')
