MaskingMediaSource needs to resolve the prepare position set for a MaskingPeriod while the source was still unprepared to the first actual prepare position. It currently assumes that the period-window offset and the default position is zero. This assumption is correct when a PlaceholderTimeline is used, but it may not be true if the real timeline is already known (e.g. when re-preparing a live stream after a playback error). Fix this by using the known timeline at the time of the preparation. Also: - Update a test that should have caught this to use lazy re-preparation. - Change the demo app code to use the recommended way to restart playback after a BehindLiveWindowException.

ExoPlayer main demo
This is the main ExoPlayer demo application. It uses ExoPlayer to play a number of test streams. It can be used as a starting point or reference project when developing other applications that make use of the ExoPlayer library.
Please see the demos README for instructions on how to build and run this demo.
