it's rather odd, the initialization above uses next_track_stream_id = 0?
Vaild stream ids start from 1, So we are toggling this between 1 and 2. So when we set next_track_stream_id to 0, that means we have opened the new next stream id and is set to prtd->stream_id. This logic is to ensure that we are not going to open next stream id twice!
ok, adding a comment would be good to show this was intentional and not a mistake.
