Thanks Warwick. That's basically what I got from Wikipedia, though I'm still not sure the advantage a media container provides. It enables streaming or has some other advantage? I checked out and built the IsoParser, but can't figure out what to pass to getTrack(long trackId). I'm not familiar with ISO 14496-13 and don't see the spec online. I've tried passing 0 or 1 and just get an empty list back.
