Roughly, one solution might be:
The user is playing a video within a web page. They click on full
screen mode.
You are describing something initiated by user action, which any
browser is quite free to support.
But if that user action is mediated through HTML, or the fullscreen
request originates in the HTML, the position is rather harder. What
you write below is only 'obviously' an embedded video for a few
seconds, alas.
But the question remains: should we provide standard markup to do
fullscreen, "since most browsers will provide an extension to do it
anyway", or not? And if so, how much do we say about the security
issues (and what)? And if not, how do we still need to say about the
security issues for browsers that do it anyway through UI, extension,
or both?
The toolbar, status bar, menu bar, and so forth are
removed, leaving just the title bar and close, minimize, and restore
controls. If there is no movement of the mouse for 2-5 seconds the
title bar disappears. With movement of the mouse again, the title bar
reappears. If the user clicks on the close control, the window returns
to its original state while continuing to play the video within the
page. Also, If the video comes to an end the window returns to its
original state.
If you don't want the title bar to control closing full screen mode,
the browser could display a special video bar during full screen mode
directly underneath the title bar. This bar could have play controls
on it. Again, the video bar (as well as the title bar) would disappear
after so many seconds of no mouse movement.
In addition to redisplaying the title bar (and potentially the video
bar) on mouse movement, it might be helpful to have a way to overlay
play controls (pause, stop, and so forth) on top of the video at this
time giving the designer a way to add those controls or supplement
those that would be in the video bar if the video bar was implemented.
Standard hotkeys in full screen mode might be nice, e.g., space bar
(play, pause).
With javascript it is already possible to make full screen web pages.
If advertisers were going to exploit this they would have by now.
Standardizing full screen video mode seems like a good idea since
users will learn what to expect and how to navigate it. Otherwise, you
potentially have a 1000 different implementations of fullscreen mode
devised by designers requiring the end user to figure out each time
how to navigate that particular implementation.

I'd say it's the other way around. We shouldn't include features that we
can't think of a way to implement them.
