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 discovery, querying and basic playback control of compliant media players, as well as a tracklist interface which is used to add context to the active media item.
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.
