獲取信號和質量數據

更新時間:2019-11-20

獲取信號和質量數據

描述

用戶正在通話中或者會議中,用戶可以獲取當前呼叫的信號強度和質量數據信息,如果在當前正在主動共享或觀看共享,用戶還能獲取共享的質量數據信息。

前提條件

用戶正在通話中或者會議中。

業(yè)務流程

圖1 獲取信號和質量數據流程

  1. SDK向UI上報事件TSDK_E_CALL_EVT_STATISTIC_INFO,通知事件攜帶參數callid標識本次呼叫,信號強度和音視頻質量數據,音視頻質量數據對應的事件數據結構TSDK_S_CALL_STATISTIC_INFO包含音頻和視頻呼叫質量信息。UI獲取到事件內容后,刷新顯示。
    說明: 

    TSDK_E_CALL_EVT_STATISTIC_INFO事件每5秒上報一次,若UI需要更高頻率獲取音視頻質量數據,可以調用tsdk_get_call_statistic_info()接口獲取。

    代碼示例:

    //c code
    case TSDK_E_CALL_EVT_STATISTIC_INFO:
    {
         handle_call_statistic_info(param1, param2, (TSDK_S_CALL_STATISTIC_INFO *)data);
         break;
    }
     
  2. 如果在當前正在主動共享或觀看共享,UI可以調用tsdk_get_share_statistic_info()接口獲取共享質量數據,傳入參數conf_handle標識本次會議句柄,返回參數數據結構TSDK_S_SHARE_STATISTIC_INFO包含共享質量數據。

    代碼示例:

    //c code
    - (VideoStreamInfo *)getSignalDataInfo
    {
        TSDK_S_SHARE_STATISTIC_INFO share_statistic_info;
        memset(&share_statistic_info, 0, sizeof(TSDK_S_SHARE_STATISTIC_INFO));
        tsdk_get_share_statistic_info(_confHandle, &share_statistic_info);
    
        VideoStreamInfo *videoStreamInfo = [[VideoStreamInfo alloc] init];
        videoStreamInfo.sendBitRate = share_statistic_info.send_bit_rate;
        videoStreamInfo.sendFrameSize = [NSString stringWithFormat:@"%u*%u",share_statistic_info.send_frame_size_width,share_statistic_info.send_frame_size_height];
        videoStreamInfo.sendFrameRate = share_statistic_info.send_frame_rate;
        videoStreamInfo.sendLossFraction = share_statistic_info.send_pkt_loss;
        videoStreamInfo.sendDelay = share_statistic_info.send_rtt;
        videoStreamInfo.sendJitter = share_statistic_info.send_jitter;
        videoStreamInfo.recvBitRate = share_statistic_info.recv_bit_rate;
        videoStreamInfo.recvFrameSize = [NSString stringWithFormat:@"%u*%u",share_statistic_info.recv_frame_size_width,share_statistic_info.recv_frame_size_height];
        videoStreamInfo.recvLossFraction = share_statistic_info.recv_pkt_loss;
        videoStreamInfo.recvFrameRate = share_statistic_info.recv_frame_rate;
        videoStreamInfo.recvDelay = share_statistic_info.recv_rtt;
        videoStreamInfo.recvJitter = share_statistic_info.recv_jitter;
    
        return videoStreamInfo;
    }
