This is what I did:

- Install and load that v4l2loopback because I have no webcam (/dev/video0
  is created)
- Install gst-plugins-good (with the v4l2 gstreamer plugin; this caused
  minor confusion on Arch Linux because I installed the gstreamer-1.0
  packages instead of Gambas' 0.10 ones.)
- As per the wiki of v4l2loopback, execute:
  $ gst-launch-0.10 videotestsrc ! v4l2sink device=/dev/video0
  which feeds /dev/video0 with sample data
- And execute:
  $ gst-launch-0.10 v4l2src device=/dev/video0 ! xvimagesink
  which displays the stuff properly.

But now I can't get the Gambas part to work because I don't understand how
these things work.
