Well, so apparently you can use more than one audio track with mpv, and it'll actually report as having two active audio tracks, instead of an audio filter or something.
Change both get_active_tracks and encode functions according to this. This only fixes multiple audio tracks, but we could also have multiple video and subtitle tracks - this is something I don't really want to get into unless I really have to.
