An option to select among several audio tracks in a video would be useful, especially for videos dubbed to several languages. The last time I checked, there was no consensus on how to implement it in HTML5, except that the video file must include all the audio files (muxed). You may want to check at http://dev.w3.org/html5/spec/media-elements.html#media-resources-with-multiple-media-tracks for more details on how to implement it in your player. Also, there's a proposed method for having the video and audio files separated: http://blog.gingertech.net/2011/05/01/html5-multi-track-audio-or-video/
