[video4linux2 @ 0xb7f6b110]Missing/Wrong parameters /dev/video0: Error while opening file
can someone please help ?
Can you please give the output of following commands as user ls -l /dev/video* groups This will check if /dev/video0 actually exists and if the permissions are right. Here's my blog post on how I got my webcam to work on Linux see if it helps http://techlog.mehulved.com/?p=24
