I want to grab video using easy cap on my raspberry pi 3. I followed the link http://raspberry-at-home.com/video-grabber-for-raspberry-pi/, but I am getting only green screen.

root@raspberrypi:~ $ uname -a
Linux raspberrypi 4.4.11-v7+ #888 SMP Mon May 23 20:10:33 BST 2016 armv7l GNU/Linux

root@raspberrypi:~# lsusb

root@raspberrypi:~# arecord -l
**** List of CAPTURE Hardware Devices ****

Subdevices: 1/1

root@raspberrypi:~# cat /proc/asound/cards

                  bcm2835 ALSA
1 [usbtv          ]: usbtv - usbtv
                  USBTV Audio at bus 1 device 12

How to resolve this issue?? any suggestion will be appreciated.


Have a look at: http://easycap.blogspot.de/2013/03/raspberry-pi-and-easycap-devices.html

The video is green if there is no signal connected to the easycap. You may check the connection of the video input.
