# Methods to be implemented by subclasses.
#
+ # Please set self._state when something changes, signals will be send
+ # by this base class when you change the state. The following states
+ # are valid:
+
+ # STATE_NOT_RUNNING: the player is not running and has released audio
+ # and video device. It doesn't matter if a child process is still
+ # running or not.
+ # STATE_IDLE: the player is not running but may still have video and
+ # audio devices locked for a next file.
+ # STATE_OPENING: the player is about to open the file and will start
+ # playing in a few seconds. If the player goes from STATE_OPENING
+ # to STATE_IDLE or STATE_NOT_RUNNING again without being in
+ # STATE_PLAYING, the 'failed' signal will be emited.
+ # STATE_PLAYING: player is playing
+ # STATE_PAUSED: player is in playback mode but pausing
+ # STATE_SHUTDOWN: player is going releasing the video and audio devices,
+ # next state has to be STATE_NOT_RUNNING
