通话质量检测

BRTC 提供 onStatistics 回调事件，它会每隔两秒钟一次向应用层上报当前网络质量，其参数包括本地推流和远端拉流质量两个部分：

示例代码

BRTCListener brtcListener = new BRTCBaseListener() {
@Override
public void onStatistics(BRTCStatistics statics) {
  Log.d(TAG, "onStatistics: " + statics.toString());
  runOnUiThread(new Runnable() {
    @Override
    public void run() {
      appCPUText.setText("cpu:"+statics.appCpu);
      sendBytesText.setText("cpu:"+statics.sendBytes);
      receiveBytesText.setText("cpu:"+statics.receiveBytes);
      if (isPublish) {
        publisherRttText.setText(statics.rtt + "ms");
        publisherLossText.setText(statics.upLoss + "%");
        ArrayList<BRTCStatistics.BRTCLocalStatistics> localArray = statics.localArray;
        for (BRTCStatistics.BRTCLocalStatistics localStatics:localArray) {
          publisherResolutionText.setText(localStatics.width + "x" + localStatics.height);
          publisherBitrateText.setText(localStatics.videoBitrate + "kbps");
          publisherFpsText.setText(localStatics.frameRate + "f/s");
          publisherSampleText.setText(localStatics.audioSampleRate + "Hz");
          publisherAudioBitrateText.setText(localStatics.audioBitrate + "kbps");
          publisherStreamTypeText.setText(localStatics.streamType);
        }
      }
      if (isPlay) {
        playerRttText.setText(statics.rtt + "ms");
        playerLossText.setText(statics.downLoss + "%");
        ArrayList<BRTCStatistics.BRTCRemoteStatistics> remoteArray = statics.remoteArray;
        for (BRTCStatistics.BRTCRemoteStatistics remoteStatics:remoteArray) {
          playerResolutionText.setText(remoteStatics.width + "x" + remoteStatics.height);
          playerBitrateText.setText(remoteStatics.videoBitrate + "kbps");
          playerFpsText.setText(remoteStatics.frameRate + "f/s");
          playerDelayText.setText(remoteStatics.jitterBufferDelay + "ms");
          playerLossText.setText(remoteStatics.finalLoss + "%");
          playerUserIdText.setText(remoteStatics.userId);
          playerSampleText.setText(remoteStatics.audioSampleRate + "Hz");
          playerAudioBitrateText.setText(remoteStatics.audioBitrate + "kbps");
          playerStreamTypeText.setText(remoteStatics.streamType);
        }
      }
    }
  });
}
};

流类型 BRTCVideoStreamType 定义如下：

• BRTCVideoStreamTypeBig(0): 主画面视频流
• BRTCVideoStreamTypeSmall(1): 小画面视频流
• BRTCVideoStreamTypeSub(2): 辅流（屏幕分享）
