对DtlsTransport源码分析：TimeoutChecker::TimeoutChecker(DtlsTransport* transport, dtls::DtlsSocketContext* ctx) : transport_(transport), socket_context_(ctx), check_seconds_(kInitialSecsPerTimeoutCheck), max_checks_(kMaxTimeoutChecks), schedul

libnice常用函数调用流程：#include <agent.h>guint stream_id;gchar buffer[] = "hello world!";gchar *ufrag = NULL, *pwd = NULL;gchar *remote_ufrag, *remote_pwd;GSList *lcands = NULL;// Create a nice agent, passing in the global default GMainContext.N

对OneToManyProcessor模块分析： DEFINE_LOGGER(OneToManyProcessor, "OneToManyProcessor"); // OneToManyProcessor的构造函数 OneToManyProcessor::OneToManyProcessor() : feedbackSink_{nullptr} { ELOG_DEBUG("OneToManyProcessor constructor"); } // OneToMan.

MediaStream有点难懂的部分：// pipeline_读取传进来的packetvoid MediaStream::onTransportData(std::shared_ptr<DataPacket> incoming_packet, Transport *transport) { if ((audio_sink_ == nullptr && video_sink_ == nullptr && fb_sink_ == nullptr)) {

继续对MediaStream进行分析：// 初始化log_stats,统计状态信息void MediaStream::initializeStats() { log_stats_->getNode().insertStat("streamId", StringStat{getId()}); log_stats_->getNode().insertStat("audioBitrate", CumulativeStat{0}); log_stats_->getNode().

针对MediaStream进行分析：// MediaStream构造函数MediaStream::MediaStream(std::shared_ptr<Worker> worker, std::shared_ptr<WebRtcConnection> connection, const std::string& media_stream_id, const std::string& media_stream_label, bool is_pu
