Code Issues Releases Wiki Activity

-Fixed inconsistent audio focus state when audio becomes noisy (e.g. headset unplugged). 

-Fixed live media sources failing when using cached data source by introducing
cacheless data sources.
-Added custom track selector to circumvent ExoPlayer's language normalization NPE.
-Updated Extractor to correctly load live streams.
-Removed deprecated deferred media source and media source manager.
-Removed Livestream exceptions.
