Cheese do not start due "GStreamer elements are missing: cluttervideosink"
I recently upgraded to Ubuntu Gnome 14.04, and when I tried to use cheese, it showed the message One or more needed GStreamer elements are missing: cluttervideosink Cheese worked just fine in 13.10 and on the live CD of 14.04. I have tried installing other GStreamer things, but nothing has worked.
You must indeed install gstreamer1.0-clutter
And also do rm -r ~/.cache/gstreamer-1.0 to erase gstreamer-1.0 folder inside of your /home/.cache hidden folder.
