Here is some examples, that shows how to work with this lib.

Configure dbus and mainloop

>>> # configure mainloop (not required if you wont expect signals)
>>> from dbus.mainloop.glib import DBusGMainLoop
>>> DBusGMainLoop(set_as_default=True)

Discover your player mpris uri

>>> # you can use get_players_uri to get current running players uri
>>> from mpris2 import get_players_uri
>>> # next raise StopIteration if not found
>>> uri = next(get_players_uri())

Connect to player

>>> # create you player
>>> from mpris2 import Player
>>> player = Player(dbus_interface_info={'dbus_uri': uri})

Call methods

>>> player.Next() # play next media

Get attributes

>>> print(player.Metadata) #current media data

Wait signal

>>> def another_handler(self, *args, **kw):
>>>     print(args, kw)
>>>
>>> player.PropertiesChanged = another_handler
>>> # python3
>>> import gi.repository.GLib
>>> mloop = gi.repository.GLib.MainLoop()
>>> mloop.run()

Other examples:

>>> # old versions mainloop
>>> import gobject
>>> mloop = gobject.MainLoop()

>>> # list all running players
>>> from mpris2 import get_players_uri
>>> print([uri for uri in get_players_uri()])
>>> # get_players_uri can be called with filter parameter
>>> get_players_uri('.+rhythmbox')
>>> # you can set it yourself
>>> uri = 'org.mpris.MediaPlayer2.gmusicbrowser'
>>> # or use one predefined
>>> from mpris2 import SomePlayers, Interfaces
>>> uri = '.'.join([Interfaces.MEDIA_PLAYER, SomePlayers.GMUSICBROWSER])

>>> # test other interfaces
>>> from mpris2 import MediaPlayer2
>>> mp2 = MediaPlayer2(dbus_interface_info={'dbus_uri': uri})
>>> # not all players implement this:
>>> from mpris2 import Playlists, TrackList
>>> pls = Playlists(dbus_interface_info={'dbus_uri': uri})
>>> tl = TrackList(dbus_interface_info={'dbus_uri': uri})
