Some applications actually don't embed the video, notably text mode or head-
less applications.

We cannot remove API calls in LibVLC 1.2 due to binary compatibility.


The fullscreen mode restriction exists for X11 due to protocol design. On the 
one hand, a window cannot be fullscreen if it has a (non-fullscreen) parent 
window. On the other hand, reparenting the window to root will cease events 
propagation to the embedding application/to the original parent window.

Loss of input events was a long-standing annoying fullscreen mode bug in the 
WxWidgets interface, then in the Qt4 interface until version 1.1. Moving 
fullscreen mode management to the window provider solved that problem.

On Win32, I don't know if the same problem exists, or if it is only a lack of 
implementation.
