Looks like there's no driver for your webcam or that this application doesn't works with your webcam, please try to use another application like the package 'cheese'

If your device is created but your image looks strange (mine was nearly completely green), you probably need this.
If the application has V4L2 support but no pixelformat support (eg: cheese) then use the following command:
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so cheese
If the application only supports the older version of V4L (skype is the most popular of this kind of software) then use this command:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
or
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so "program"
Hint: You also might want to put a line like the following into your .bashrc or .xinitrc so you don't have to type that long command all the time:
export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so
or
export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
or
export LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so
