This is a copy of mprisV2.2 documentation
That also works as python lib.

The Media Player Remote Interfacing Specification is a standard D-Bus interface which aims to provide a common programmatic API for controlling media players.
It provides a mechanism for compliant media players discovery, basic playback and media player state control as well as a tracklist interface which is used to add context to the current item.
From 2.1 to 2.2:
- Added the optional Fullscreen and CanSetFullscreen properties to the org.mpris.MediaPlayer2 interface.
- The path /org/mpris/MediaPlayer2/TrackList/NoTrack now represents “no track” where required in the org.mpris.MediaPlayer2.TrackList interface (since empty paths are not allowed by D-Bus).
- The suggested unique instance identifier no longer violates the D-Bus specification by begining with a digit.
From 2.0 to 2.1:
- Added the optional org.mpris.MediaPlayer2.Playlists interface.
Bus Name Policy¶
Each media player must request a unique bus name which begins with org.mpris.MediaPlayer2. For example:
This allows clients to list available media players (either already running or which can be started via D-Bus activation)
In the case where the media player allows multiple instances running simultaneously, each additional instance should request a unique bus name, adding a dot and a unique identifier to its usual bus name, such as one based on a UNIX process id. For example, this could be:
Note: According to the D-Bus specification, the unique identifier “must only contain the ASCII characters ‘[A-Z][a-z][0-9]_-‘” and “must not begin with a digit”.
The media player must expose the /org/mpris/MediaPlayer2 object path, which must implement the following interfaces:
The /org/mpris/MediaPlayer2 object may implement the org.mpris.MediaPlayer2.TrackList interface.
The /org/mpris/MediaPlayer2 object may implement the org.mpris.MediaPlayer2.Playlists interface.
The PropertiesChanged signal¶
The MPRIS uses the org.freedesktop.DBus.Properties.PropertiesChanged signal to notify clients of changes in the media player state. If a client implementation uses D-Bus bindings which do not support this signal, then it should connect to it manually. If a media player implementation uses D-Bus bindings which do not support this signal, then it should send it manually
2010-09-26: Added EmitsChangedSignal annotation to Volume property on the Player interface.
2011-01-26: Added PlaylistChanged signal to the Playlists interface.
