Images are not written to VideoStream on Manjaro GNU/Linux

[Deleted user]

This code produced an empty buffer on Manjaro GNU/Linux, although it runs absolutely correctly on GNU/Linux Mint 17.

#!/usr/bin/env python2
from SimpleCV import Camera, VideoStream
from datetime import datetime
from time import sleep

cam = Camera()


def get_buffer_name():
    now = datetime.now()
    return 'buffer{}'.format(now.second)


def write_video(video_len):
    buffer_video_name = '{}.avi'.format(get_buffer_name())

    vs = VideoStream(filename=buffer_video_name)
    delay = 1./25

    current_video_len = 0
    while current_video_len < video_len:
        img = cam.getImage()
        sleep(delay)
        vs.writeFrame(img)
        current_video_len = vs.framecount/25


if __name__ == '__main__':
    write_video(5)

Images from Camera are actually taken and can be saved which I have tested with my little lab work.
