I wanted to try v4l on my Ubuntu development system first - it's this that isn't working: If you don't already have a v4l2 output device on your dev system, then you're unlikely to be able to use v4l2sink. I had a quick look around for virtual v4l2 output devices, but didn't see any (I only found virtual input devices). I'm not sure that testing v4l2sink on your dev system is going to tell you much though. It would be roughly equivalent to testing with xvimagesink or autovideosink.
