Remarks

A typical use of this event is if you are implementing your own transport controls. You can respond to this event by checking to see whether the source is a MediaSource, MediaPlaybackItem, or MediaPlaybackList and then update your UI accordingly. For example, if the source is a MediaPlaybackItem, you could subscribe to the list of audio and caption tracks and update the list in your UI so that the user can select the active track.
