## Object Hierarchy

        GInterface
        ╰── RygelPlayerController

## Prerequisites

RygelPlayerController requires GObject.

## Description

These states are: # URI # MetaData # Number of tracks # Current track # Playback state

In case of playlists this class will also control the player. It needs to proxy the playback state to react on end of item to be able to switch to the next item.
