摘要
随着人们生活水平的逐渐提高,人们对安全越来越重视,视频监控在很多领域逐渐普及。在OMAP平台上运用Gstreamer多媒体框架,实现了一个集视频采集、视频编码和视频传输的C/S结构网络视频监控系统。视频采集基于V4L2应用程序接口,视频编码采用H.264编码,网络传输承载于RTP协议族之上。系统包含服务端和客户端,基于插件的系统结构使该系统具有易维护、易扩展的特点。在OMAP平台上的测试结果表明,该系统整体延时在1s以下,满足了实时监控需求,可应用于实际生产。
With the gradual improvement of people＇ s living standards, people have paid more attention to security, and video surveillance is gradually spread around many fields. In this paper,a network video surveillance system with C/S structure including video capture,en- coding and transmission is developed under OMAP platform based on Gstreamer multimedia framework. Video capture is based on V4L2 application program interface, video encoding is using H. 264 coding standard, and network transmission is based on the RTP family. This system includes server and client, and it＇ s easy to maintain and expand because of the plugin-based structure. Test results on the OMAP platform show that the overall system delay of about 1 seconds or less, can meet the needs of real-time monitoring, which can be used in actual production.
