断网续播

** hls.startLoad();**

先在网络错误里面寻找

hls.on(Hls.Events.ERROR, function (event, data) {
  if (data.fatal) {
    switch (data.type) {
      case Hls.ErrorTypes.NETWORK_ERROR:
        // try to recover network error
        console.log('fatal network error encountered, try to recover');
        hls.startLoad();
        break;
      case Hls.ErrorTypes.MEDIA_ERROR:
        console.log('fatal media error encountered, try to recover');
        hls.recoverMediaError();
        break;
      default:
        // cannot recover
        hls.destroy();
        break;
    }
  }
});
