Exoplayer（2.0.0）在播放實時HLS視頻時給予BehindLiveWindowException

Answer 1

根據谷歌版本2.0是非常不穩定的實時HLS播放。所以我不推薦現在切換到2.0的Live HLS播放。 即將到來的問題BehindLiveWindowException，Google仍在努力解決此問題，作爲Live HLS查找功能的一部分。在onError的再次 https://github.com/google/ExoPlayer/issues/1782

作爲一個臨時的解決辦法u能調用preparePlayer（）（）：

請在這裏追蹤狀態。

@Ovierride 
public void onError(Exception e) { 

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