复杂硬件环境下流媒体服务器的设计实现

Design and Implementation of Streaming Media Server Above Unified Complex Hardware Environment

随着大型视频监控系统底层硬件环境越来越复杂,原先调用各厂商SDK进行编解码的方式变得越来越臃肿和缓慢;针对这一问题,提出了一种流媒体服务器的设计,它基于标准流媒体协议保证媒体转发的通用性,利用统一接口来屏蔽底层硬件差异,并在网络传输中进行拥塞自适应;经实际应用表明只用该服务器就可处理不同DVR视频流的转发,上层应用无需关注底层硬件信息,并且在有限带宽下可以获得更好的性能;为实际大型视频监控系统提供了参考技术方案。

As the underlying hardware environment of large - scale video surveillance systems more and more complex ; Call the manu- facturer SDK to encode and decode the system becomes more and more bloated and slow; To solve this problem, propose a design of streaming media server, which is based on the standard streaming media protocols to ensure the universal of streaming forword, using unified interface to shield underlying hardware differences, and can auto - adapt the network congestion ; The practical application shows that only a streaming media server can handle video streams from different DVRs forwarding ; upper applications without concern about the underlying hardware information, and can get better performance on limited bandwidth. It provides a reference technical solutions for actual large- scale video surveillance system
