通话质量检测

编辑文档更新于 2025-12-15 10:47:33

BRTC 提供两套关于通话质量反馈的回调：

onStatistics 回调事件，它会每隔两秒钟上报当前的音视频推拉流度量数据。您可以通过这些度量数据来评价整体的通话质量。
onNetworkQuality 回调事件，它根据 SDK 自定义的一套评价原则，提供了简单的几档评价结果，属于颗粒度比较粗的评价结果。对于不需要特别详细的度量数据时，也可以使用这个回调来完成通话质量的大致评价。

示例代码

#pragma mark - >>>>>>>>>>>>>>>>>>>BRTC 回调<<<<<<<<<<<<<<<<<<<<<<
- (void)onStatistics:(BRTCStatistics *)statistics {
  NSMutableString *text = [NSMutableString string];
  [text appendFormat:@"RTT: %d ms \n", statistics.rtt];
  [text appendFormat:@"up Packet Loss: %u\n",statistics.upLoss];
  [text appendFormat:@"down Packet Loss: %u\n",statistics.downLoss];
  [text appendFormat:@"cpu usage: %u\n",statistics.cpu];
  for (BRTCLocalStatistics *local in statistics) {
    [text appendFormat:@"Resolution: %d X %d\n",local.width, local.height];
    [text appendFormat:@"Video Send Bitrate: %.2u kps \n", local.videoBitrate];
    [text appendFormat:@"Audio Send Bitrate: %.2u kps \n", local.audioBitrate];
    [text appendFormat:@"Video Send FPS: %.1u fps \n", local.frameRate];
    [text appendFormat:@"local streamType: %d \n", local.streamType];
  }
  for (remoteStatistics *remote in statistics) {
    [text appendFormat:@"Resolution: %d X %d\n", remote.width,remote.height];
    [text appendFormat:@"Audio Recv Bitrate: %.2u kps \n", remote.audioBitrate];
    [text appendFormat:@"Video Recv Bitrate: %.2u kps \n", remote.videoBitrate];
    [text appendFormat:@"Video Recv FPS: %.1u fps \n", remote.frameRate];
    [text appendFormat:@"Delay: %d ms \n", remote.jitterBufferDelay];
    [text appendFormat:@"remote stream type: %d \n", remote.streamType];
  }
  [self appendLog:[NSString stringWithFormat:@"quality: %@", text]];
}

- (void)onNetworkQuality:(NSArray<BRTCCollectionQuality *> *)qualityArray {
  for (BRTCCollectionQuality *quality in qualityArray) {
    NSLog(@"onNetworkQuality, %@, %ld", quality.userId, quality.qualityLevel);
  }
