    服务端的处理

    1. // 主函数中调用web接口安装函数
    2. installWebApi
    3.   addHttpListener();
    4.   api_regist("/index/api/webrtc",[](API_ARGS_STRING_ASYNC){
    5.     auto type = allArgs["type"];
    6.     auto offer = allArgs.getArgs();
    7.     WebRtcPluginManager::Instance().getAnswerSdp(*(static_cast<Session *>(&sender)), type,
    8.                                                    WebRtcArgsImp(allArgs, sender.getIdentifier()),
    9.                                                    [invoker, val, offer, headerOut](const WebRtcInterface &exchanger) mutable {
    10.             headerOut["Content-Type"] = HttpFileManager::getContentType(".json");
    11.             headerOut["Access-Control-Allow-Origin"] = "*";
    12.             val["sdp"] = const_cast<WebRtcInterface &>(exchanger).getAnswerSdp(offer);
    13.             val["id"] = exchanger.getIdentifier();
    14.             val["type"] = "answer";
    15.             invoker(200, headerOut, val.toStyledString());
    16.         });
    17.     });
    18.  
    19.  
    20. addHttpListener
    21.    //注册监听kBroadcastHttpRequest事件
    22.     NoticeCenter::Instance().addListener(&web_api_tag, Broadcast::kBroadcastHttpRequest,
    23.                                          [](BroadcastHttpRequestArgs) {
    24.       auto it = s_map_api.find(parser.Url());
    25.       it->second(parser, invoker, sender);
    26. 	}

    根据url找到对应的事件回调，最终会调用WebRtcPluginManager::Instance().getAnswerSdp。

    1. WebRtcPluginManager::getAnswerSdp
    2.   auto it = _map_creator.find(type);
    3.   it->second(sender, args, cb);
    4.   
    5.  
    6. // 静态注册插件
    7. WebRtcPluginManager::Instance().registerPlugin("play", play_plugin);
    8.  
    9.  
    10. void play_plugin(Session &sender, const WebRtcArgs &args, const WebRtcPluginManager::onCreateRtc &cb)
    11.   // 使用rtsp媒体源，两者均是传输的rtp流
    12.   info._schema = RTSP_SCHEMA;
    13.   MediaSource::findAsync(info, session_ptr, [=](const MediaSource::Ptr &src_in) mutable {
    14.     auto src = dynamic_pointer_cast<RtspMediaSource>(src_in);
    15.     // 还原成rtc，目的是为了hook时识别哪种播放协议
    16.     info._schema = RTC_SCHEMA;
    17.     auto rtc = WebRtcPlayer::create(EventPollerPool::Instance().getPoller(), src, info, preferred_tcp);
    18.       cb(*rtc); // 发送answer SDP给web端
    19.     });

     播放

    拉流

    stun , dtls  先握手把对称密钥通过非对称加密方式 传输 过去后，之后的数据都通过这个对称密钥进行加密。 srtp 加密 rtp . .
    Web端首先根据协商的IP和端口，服务端webrtc的端口是8000，发送STUN命令再次获取STUN地址。
    首次连接，服务端会创建对应的session。

    WebRtcSession::WebRtcSession(const Socket::Ptr &sock) : Session(sock)
      socklen_t addr_len = sizeof(_peer_addr);
      getpeername(sock->rawFD(), (struct sockaddr *)&_peer_addr, &addr_len);
      

    WebRtcSession::onRecv_l(const char *data, size_t len)
      // 首次进入，根据username获取之前创建的transport.
      auto user_name = getUserName(data, len); // 此处的username就是之前设置的transport标识
      auto transport = WebRtcTransportManager::Instance().getItem(user_name);
      transport->setSession(shared_from_this());
      _transport = std::move(transport);
      _transport->inputSockData((char *)data, len, (struct sockaddr *)&_peer_addr);
      
      
    WebRtcTransport::inputSockData
      // 处理STUN消息
      if (RTC::StunPacket::IsStun((const uint8_t *)buf, len))
        std::unique_ptr packet(RTC::StunPacket::Parse((const uint8_t *)buf, len));
        _ice_server->ProcessStunPacket(packet.get(), tuple);
        return;
        
      // 处理    
      if (is_dtls(buf))
        _dtls_transport->ProcessDtlsData((uint8_t *)buf, len);
        return;
        
      // 由于是拉流，不存在rtp数据，但是有rtcp数据
      if (is_rtcp(buf))
        if (_srtp_session_recv->DecryptSrtcp((uint8_t *)buf, &len))
          onRtcp(buf, len);


    DTLS交互完成后，接下来启动媒体传输

    WebRtcTransport::OnDtlsTransportConnected
      onStartWebRTC();


    WebRtcPlayer::onStartWebRTC
      WebRtcTransportImp::onStartWebRTC();
      _reader = _play_src->getRing()->attach(getPoller(), true);
      weak_ptr weak_self = static_pointer_cast(shared_from_this());
      weak_ptr weak_session = getSession();
      _reader->setReadCB([weak_self](const RtspMediaSource::RingDataType &pkt) {
        size_t i = 0;
        pkt->for_each([&](const RtpPacket::Ptr &rtp) {
          strong_self->onSendRtp(rtp, ++i == pkt->size());
        });
      });
     

    transport-cc goog-remb (webrtc中的两种码率算法）

    "Transport-CC" 是 WebRTC（Web实时通信）中的一种传输拥塞控制机制，用于管理实时媒体（音频和视频）的传输，以适应网络状况，确保通信的连续性。它有助于根据网络条件调整媒体的比特率，以确保在可用带宽的情况下提供流畅且不中断的通信体验。它用于避免过载网络，以提供最佳可能的质量。

    "Goog-REMB"（Google Receiver Estimated Maximum Bitrate）是由Google开发的一种扩展，用于实时传输控制协议（RTCP）。它在WebRTC中用于估算接收方对特定媒体流能够处理的最大比特率。然后，这些信息会传达给发送方，使其能够调整正在传输的媒体的比特率，以匹配接收方的容量，从而提高通信的整体质量。

    这些术语与WebRTC的技术相关，用于优化互联网上的实时通信的质量和性能

    主要核心主体的创建

    RtspMediaSourceImp的创建

    入口处的CB，即是对http的回复

    影响到何时生成recorder的代码

    下面的invoker为上图中传过来的invoker. 其中最难的就是其中的obj,就是on_publish执行回来的result里的值 。

     研发的环境不对，如下

    生产环境 2.8是对的，如下

     Mediasource之主要解复合MultiMediaSourceMuxer

    下面的初始化直接决定着，什么时候生成recorder,是一拉流就有。比如上面record-push-live设置为true时，那么每段放视频，都会进行录制；反之，就直接取决于配置文件是的enable_mp4=false 

     Mediasource之主要复合

    录相

    当上述开关正确设置上，就可以达到当打开开关时，才进行录制

    trackready
