 * SECTION:rb-player
 * @short_description: playback backend interface
 * @include: rb-player.h
 *
 * This is the interface implemented by the rhythmbox playback backends.
 * It allows the caller to control playback (open, play, pause, close), 
 * seek (set_time), control volume (get_volume, set_volume)
 * and receive playback state information (get_time, various signals).
 *
 * The playback interface allows for multiple streams to be playing (or at
 * least open) concurrently. The caller associates some data with each stream
 * it opens (#rb_player_open), which is included in the paramters with each
 * signal emitted. The caller should not assume that the new stream is playing
 * immediately upon returning from #rb_player_play. Instead, it should use
 * the 'playing-stream' signal to determine that.
 *
 * The player implementation should emit signals for metadata extracted from the
 * stream using the 'info' signal
 *
 * While playing, the player implementation should emit 'tick' signals frequently
 * enough to update an elapsed/remaining time display consistently.  The duration
 * value included in tick signal emissions is used to prepare the next stream before
 * the current stream reaches EOS, so it should be updated for each emission to account
 * for variable bitrate streams that produce inaccurate duration estimates early on.
 *
 * When playing a stream from the network, the player can report buffering status
 * using the 'buffering' signal.  The value included in the signal indicates the
 * percentage of the buffer that has been filled.
 *
 * The 'event' signal can be used to communicate events from the player to the application.
 * For GStreamer-based player implementations, events are triggered by elements in the
 * pipeline posting application messages.  The name of the message becomes the name of the
 * event.
