摘　　要：基于视频监控应用领域应用广泛,对视频监控的实时性已成为检验安防系统的重要标准,为此设计以TE6410开发板为硬件平台为核心基于Linux系统实现H. 264软件编码的实时监控系统。平台采用cmos摄像头基于V4L2接口采集视频,采用X264软件编码压缩,实现了视频的高度压缩比;基于RTP协议打包封装H. 264视频流经网络传输到VLC播放器,显示监控画面。经实验测试结果证明,系统监控图像清晰,播放流畅达到了实时监控的效果。Because of the widely used video surveillance, the real-time video monitoring has become an important standard to test security system. This paper designed a real-time monitoring system by using TE6410 development board as the core of hardware platform, using Linux to realize the H.264 software coding and real-time monitoring. Video acquisition platform adopts the cmos camera based on V4L2 interface, USES the X264 software is used for coding compression to realize a high compression ratio, H.264 video flow is packed by using RTP protocol and sent through the network to the VLC, the image then is displayed in monitor screen. Through experimental tests, the results show that monitoring image is clear and smooth, it achieves the effect of the real-time monitoring.
