Not that useful and a battery killer for sure.
You need the packages
x11-utils
gst-tools
and maybe
gstreamer0.10-plugins-good
gstreamer0.10-plugins-good-extra

- open the lenscover and close the camera app
- open a xterm and enter:
gst-launch-0.10 v4l2camsrc driver-name=omap3cam ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! xvimagesink
- open another xterm and enter:
xprop -name "gst-launch-0.10" -f _HILDON_LIVE_DESKTOP_BACKGROUND 32i -set _HILDON_LIVE_DESKTOP_BACKGROUND -1

:-)


other gst-launch commands:
gst-launch-0.10 v4l2camsrc driver-name=omap3cam ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! quarktv ! xvimagesink

Audio:
gst-launch-0.10 pulsesrc ! audioconvert ! monoscope ! ffmpegcolorspace ! xvimagesink

it works!

apt-get couldn't find gst-tools, but I installed gstreamer-tools instead.

Code:
wmctrl -i -r $(wmctrl -l | grep gst-launch-0.10 | awk '{print $1}') -b add,fullscreen
to make it fullscreen, nice trick, never knew about that X11 flag

Code:
sudo gainroot
apt-get install gstreamer-tools
If it says can't fetch or something then try again, it works for me..


But this doesn't work for me Nicolai, after the second code it just stops there showing ">" And the wallpaper doesn't change...
It does show some white dots though...

I already open the camera lens and the gstreamer is running, but it doesn't change the wallpaper, do i need to do something first?
