This event is used to signal if, during operation, the settings of the track changed in such a way that it is not possible to satisfy the constraints for this track any longer. If so, the offending track is muted and the event is raised so that the application can address the problem appropriately. This is useful for getting more consistent behavior across browsers and allow for better control for the application.
