srs4.0 webrtc分析（四）推流、播放类逻辑分析

介绍

 分析srs4.0 webrtc 模块 ，推流端对应SrsRtcPublishStream、播放端对应SrsRtcPlayStream 类，本文将简单介绍这两个类。

推流类

SrsRtcPublishStream，关键代码

// A RTC publish stream, client push and publish stream to SRS.
class SrsRtcPublishStream : virtual public ISrsHourGlass, virtual public ISrsRtpPacketDecodeHandler
    , virtual public ISrsRtcPublishStream, virtual public ISrsRtcPLIWorkerHandler
{
  private:
    SrsRequest* req;
    SrsRtcStream* source;
  private:
    // track vector
    std::vector audio_tracks_;//描述音频流信息
    std::vector video_tracks_;
  public:
    srs_error_t on_rtp(char* buf, int nb_buf);
  private:
    srs_error_t do_on_rtp(char* plaintext, int nb_plaintext);
