摘要
为解决本校园用户提出的根据活动特点灵活选择直播观众群体以及对直播系统强实时性、多功能性的要求,从视频编解码、流媒体传输协议以及实时转码方面分析了影响流媒体直播性能的关键因素,并结合当前流行的云计算服务模式,在校内传统网络直播架构的基础上提出基于混合云架构的视频直播系统,实现了直播用户灵活选择受众群体、多终端接入、多功能云端化的要求。
In order to solve the problem of flexible selection of video live audiences according to the characteristics of the event and the strong real time and multi-functionality of the live system proposed by the campus users,this article analyzes the key factors influencing the live broadcasting of streaming media from the aspects of video codec,streaming media transmission protocols,and real-time transcoding. Considering the current popular cloud computing service model,the article puts forward a video live system based on the hybrid cloud architecture,which meets the requirements for flexible selection of audiences,multi-terminal access,and multi-functions provided in cloud platform.
