My use case is people releasing the media player and libvlc from the UI 
thread, for instance while destroying their main window. So the module is 
closed, lib is released and the main loop still exists.

If we can only create/release libvlc from outside UI loops, I think it should 
be clearly stated in the doc.

NSView can only be manipulated from the main thread of an application. AFAIK, 
the other Vout  don't have such restrictions.
