because media information is available only for the current item being 
played. I use libvlc_media_get_meta with the media player given as 
argument, not a given playlist item.//
Since info is available in VLC client GUI thru the "Tool/Media 
information menu", I propose to create  an object called  
MediaInformation and attach it directly under the player root object.
