That is irrelevant because running VLC plugin code after LibVLC is destroyed
is a big NO NO. Hence retaining the code after LibVLC is pointless.
In fact, LibVLC media player API more or less explicitly warrants that nothing
will happen after libvlc_media_player_stop() has returned.

There is no such restrictions.
You can´t use libvlc functions from libvlc event callbacks, and you must
ensure use by a single thread at a time for any given object. That´s all.
