Constant libmpv_sys::mpv_event_id_MPV_EVENT_TRACKS_CHANGED

pub const mpv_event_id_MPV_EVENT_TRACKS_CHANGED: mpv_event_id = 9;

The list of video/audio/subtitle tracks was changed. (E.g. a new track was found. This doesn't necessarily indicate a track switch; for this, MPV_EVENT_TRACK_SWITCHED is used.)

@deprecated This is equivalent to using mpv_observe_property() on the "track-list" property. The event is redundant, and might be removed in the far future.
