I would like to show a video inside a web browser, in full screen using HTML5 tags.

My problem is that I am unable to avoid margins (blank borders), in other words I can't obtain a real FULL SCREEN
In the screeenshot here below I show the unwanted margins:

Any idea to get a full-full-screen ? :-)
BTW, double clicking on the image I get finally a real full screen but I think in this case come in the game thge flash player, isn't it ? The point is that i would like to visualize the full screen video also froma a smart/phone/tablet browser (without any flash player ....)
Many thanks! giorgio
