I get an error when trying to run [player.set_video_title_display(6,5000) ]

the code:
Instance = vlc.Instance()
player = Instance.media_player_new()
Media = Instance.media_new_location(url)
player.set_media(Media)
x= Media.get_meta(0)
player.set_title(1)
player.set_video_title_display(6,5000)
player.play()

the error :

Any ideas ?-
