中文摘要: 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。
Abstract: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.
