The problem that Erwan describes, where the same system resources sustain both 
the GUI and the video window but it's undefined which gets released first, is a 
text book case of reference counting. Surely, you don't need an example of 
reference counting. Thus, that problem is entirely within the plugin that 
contains the GUI and window provider, and does not concern the core in any 
way.

It is however a symptom of a more abstract problem that the "main" interface 
want to register some monolith/singleton with the VLC instance, before the 
playlist starts, and deregister them until after the playlist stops, notably 
the window provider and the log callback. Solving that needs a change in the 
main UIs and in the API/ABI between main UIs and core. Again, this does not 
concern the window provider API/ABI in any way.
