Thansk for following advise and help of the videolan developers. I hope you
will continue to do so, because the works is not yet finished for this
feature. Here are my comments:

1) use function names that tell what they do

+// Make a copy of an NPVariant.
+NPVariant saveNPVariant(const NPVariant& original)

Use a more instructive name. It is meant to copy a NPVariant, then name it
eg: copyNPVariant() iso saveNPVariant(). 'save' indicates more permanent
storage and not making a copy.

+void eventFct(const libvlc_event_t* event, void *param)

Use eg; event_callback() iso eventFct(). Callback is more descriptive.

2) use ID_event_* names here iso ID_root_*. You are extending API's for
eventObj not for rootObj.

+enum LibvlcEventNPObjectMethodIds
+    ID_root_addListener,
+    ID_root_removeListeners,

3) You methods/lists of type vector, but nowhere in the code you use that
fact to your benefit.

 class VlcPlugin

     bool  player_has_vout( libvlc_exception_t * );

+    // Events related members
+    std::vector<EventListener*> eventListeners; // List of registered
+    std::vector<const NPUTF8*> eventList; // List of event sent by
VLC that must be returned to JS.
+    eventtypes_bitmap_t eventToCatch;

+    static bool canUseEventListener();
     bool playlist_select(int,libvlc_exception_t *);
     void set_player_window( libvlc_exception_t * );

Kind regards,
