Audio and video QoS collection: WebRTC congestion control+smooth transmission+packet loss retransmission

This course includes three major technologies of WebRTC weak network optimization: congestion control/bandwidth estimation technology GCC, smooth transmission technology pacer, packet loss retransmission technology nack. The course adopts a theoretical+practical approach, gradually iterates, advances step by step, and cooperates with experimental tests. What you see is what you get.
