MPV_EVENT_TRACK_SWITCHED constant
int
const MPV_EVENT_TRACK_SWITCHED
A video/audio/subtitle track was switched on or off.
@deprecated This is equivalent to using mpv_observe_property() on the "vid", "aid", and "sid" properties. The event is redundant, and might be removed in the far future.
Implementation
static const int MPV_EVENT_TRACK_SWITCHED = 10;
