Thank you for your quick reply Tim-Philipp.

gst-launch-0.10 -v v4l2src device=/dev/video0 ! fakesink
Shows:

This continues endless (I think, I waited untill offset 140)


The output of gst-inspect-0.10 v4l2src | grep Version  is:
  Version:        0.10.29

I indeed seems like I'm on an old version...
