This works:

I'm using Fedora 21 and following versions of gstreamer:
$ gst-launch-0.10 --version
gst-launch-0.10 version 0.10.36
GStreamer 0.10.36
http://download.fedoraproject.org
$ gst-launch-1.0 --version
gst-launch-1.0 version 1.4.4
GStreamer 1.4.4
http://download.fedoraproject.org
/dev/video1 device being created by v4l2loopback. I have to use gstreamer 1.0, because it's the only version supported by gnome-shell's desktop capture interface.
