根据Google Ver 2.0，Live HLS游戏非常不稳定。所以我不建议现在切换到2.0用于Live HLS播放。来到您的问题BehindLiveWindowException，Google仍在努力解决此问题，作为Live HLS搜索功能的一部分。

请在此处跟踪状态： https://github.com/google/ExoPlayer/issues/1782

作为临时修复，您可以在onError（）中再次调用preparePlayer（）。

 @Ovierride
 public void onError(Exception e) {

   if (e instanceof ExoPlaybackException
            && e.getCause() instanceof BehindLiveWindowException) {
      preparePlayer(true);
    }
 }

Exoplayer（2.0.0）在播放实时HLS视频时给出BehindLiveWindowException
