An improved Real-Time Video Communication System

摘要

In this paper, we optimized the Linphone-based real-time video communication system. Firstly, we used HEVC to replace the H.264 in order to reduce the bandwidth pressure while reducing the buffer delay by configuring the appropriate encoding parameters. Secondly, we added an effective bitrate adaptive algorithm based on additive increase and multiplicative decrease (AIMD) in the system, which can effectively reduce the packet loss rate in the network with high bandwidth fluctuations.
