VLC Python EventManager callback type?

Here is basic code for the more recent vlc.py using the event_manager:

import vlc
import time
import sys

finish = 0

def SongFinished(event):
    global finish
    print("\nEvent reports - finished")
    finish = 1

def pos_callback(event, player):
    sec = player.get_time() / 1000
    m, s = divmod(sec, 60)
    npos = event.u.new_position * 100
    sys.stdout.write('\r%s %02d:%02d (%.2f%%)' % ('Position', m, s, npos))
    sys.stdout.flush()

instance = vlc.Instance()
player = instance.media_player_new()
media = instance.media_new_path('vp1.mp3') #Your audio file here
player.set_media(media)
events = player.event_manager()
events.event_attach(vlc.EventType.MediaPlayerEndReached, SongFinished)
events.event_attach(vlc.EventType.MediaPlayerPositionChanged, pos_callback, player)

player.play()
while finish == 0:
    time.sleep(0.5)

Note: there are quite a few events for the media player that can be monitored in this way.

MediaPlayerMediaChanged
MediaPlayerNothingSpecial
MediaPlayerOpening
MediaPlayerBuffering
MediaPlayerPlaying
MediaPlayerPaused
MediaPlayerStopped
MediaPlayerForward
MediaPlayerBackward
MediaPlayerEndReached
MediaPlayerEncounteredError
MediaPlayerTimeChanged
MediaPlayerPositionChanged
MediaPlayerSeekableChanged
MediaPlayerPausableChanged
MediaPlayerTitleChanged
MediaPlayerSnapshotTaken
MediaPlayerLengthChanged
MediaPlayerVout
MediaPlayerScrambledChanged
MediaPlayerESAdded
MediaPlayerESDeleted
MediaPlayerESSelected
MediaPlayerCorked
MediaPlayerUncorked
MediaPlayerMuted
MediaPlayerUnmuted
MediaPlayerAudioVolume
MediaPlayerAudioDevice    

For the full current list, search for class EventType in the code at

Found it, VLC.py includes a small decorator ctypes function for wrapping callbacks:

callbackmethod=ctypes.CFUNCTYPE(None, Event, ctypes.c_void_p)

To use:

@callbackmethod
def SongFinished(self, data):
    print data

.event_attach(vlc.EventType.MediaPlayerEndReached, SongFinished, 1)
