In all other media player states the screensaver does not activate and cannot interrupt content playback. Calling the method event.preventDefault() will prevent the state of the screensaver from changing. The event.payload.mode property has the value on if the screensaver is allowed to activate and off if the screensaver is not allowed to activate.

The event.payload.selectedURL is the URL about to start playback. The event.payload.startIndex is the time index to start playback of the selected URL. The event.payload.callbackHandler is a callback to start playback yourself. This provides an alternative method to change the URL just before playback. By calling the method event.preventDefault() on the event and then calling event.payload.callbackHandler(url, timeIndex) you can provide an alternative url to play along with a new timeIndex. This is not a general use case. Instead you should use custom playlist entry objects to change the URL.
