The current spec does not say how AudioTrack.id & VideoTrack.id are generated.
This needs to be defined because the underlying track IDs in the presentation
are not necessarily constant (see section 2.4 bullet 2).


My suggestion is for the UA to generate unique ID strings for each track that
stay constant throughout the presentation. I think allowing them to change
during playback would be very confusing to the web application.
