This has several advantages over the current manual demuxing currently being performed. PlaybackManager hides the specific demuxer being used, which will allow more codecs to be added transparently to LibWeb. It also provides buffering and controls playback rate for us. Further, it will allow us to much more easily implement the "media timeline" to render a timestamp and implement seeking.
