How to hide soft touch buttons on devices like Galaxy Nexus [duplicate]

Question

I have just tried VLC app on Galaxy Nexus. The only problem it has is that the touch buttons (back, home and menù) on galaxy nexus are not hidden like it happens on Youtube app.

How is it possible to control touch buttons behaviour?

Thanks

You are right, the VLC player does this without root permissions ( on my phone it does ;) ). I found this on stackoverflow:
