- play URL (any http link to an ogg, mp3 or m4a file)
- play from RTMP (only mp3 or m4a files)
- adjust volume
- callback: onStart, onFinish, onPlay(secs_played, percent_loaded), onVolumeChange, onSeek
The GUI needs to be skinnable. It has to display play/pause button, time played, volume and a seek slider.
