May be this is because of using V4L2 drivers?! I found something in the 
output. Question to ClaudiusMaximus: Which OS, version and V4L-version 
did you use with your commandline?

Just for completeness, here is my output to the above command:

 As the V4L1 compatibility layer is broken, this may not work.
 If you encounter any problems, use driver=v4l2 instead.
 Bugreports on driver=v4l with v4l2 drivers will be ignored.
