Cast Extension: Detecting track changes while casting

How to detect that track has finished or has changed for CastPlayer? For normal player I use onTracksChanged which detect that I skip to another track and onPositionDiscontinuity with reason == 0 to detect that track is finished.
For CastPlayer onTracksChanged is never called and onPositionDiscontinuity with reason == 0 is called very often when I connect to Chromecast and when I skip to another track.
