I have a problem using a web camera (defender c-110) on mk802ii with debian armhf from here:

     $ avconv -f video4linux2 -r 5 -s 640x480 -i /dev/video0 out.avi
     avconv version 0.8.6-6:0.8.6-1, Copyright (c) 2000-2013 the Libav developers
     built on Mar 24 2013 22:04:47 with gcc 4.6.3
     [video4linux2 @ 0x168bc40] The driver changed the time per frame from 1/5 to 1/30
     [video4linux2 @ 0x168bc40] ioctl(VIDIOC_STREAMON): Message too long
     /dev/video0: Message too long

The same error I recieve using this example. What does this error means and what do I have to do?
