摘要
随着网络通信技术和多媒体技术的迅猛发展,嵌入式的视频监控设备需求量也在增加。提出了一种嵌入式的视频服务器解决方案,方案中采用高压缩比、高鲁棒性的H.264视频编码算法;对开源代码Live555进行功能扩展并作为流媒体服务模块,负责处理客户端RTSP连接请求、音视频数据的RTP打包和发送等功能。最后,使用流媒体客户端VLC对视频服务器进行功能测试,可获得实时性较好、流畅度较高的图像和声音。
As the rapid development of network communication and multimedia technology,demand of embedded video surveillance devices is also increasing.This paper provides an embedded video server solution,which uses a high robustness and high compression algorithm-H.264,to encode video source and transplants the open-source Live555 as streaming media module which is responsible for receiving external RTSP connection request,packing sound and video data in a RTP way,as well as sending them.In the end,lots of tests have been done by using standard streaming media client VLC,which prove a timely,fluent and better picture/sound quality.
