基于ARM11的视频监控系统设计

摘要

In order to satisfy the requirement of the remote video surveillance, the design of video surveillance system based on ARM11 and embedded Linux system is used in the paper. This article uses the V4L2 interface for data collection, selected with a high compression efficiency of PL264 compression standard, by the CPU internal integrated MFC module hardware compression of video streams, and transplanted to the boa server write a CGI script to respond the remote client to realize the various video functional modules of the overall system design including the collection, coding, transmission, display, the API interface to SDL and FFmpeg libraries in the client is used to complete the network transmission to the client,and the decoding and playback of the video data.%为了实现远程视频监控的功能,提出了一种基于ARM 11和嵌入式Linux的远程视频服务器的方案.使用V4L2接口对数据进行采集,选择了具有很高压缩效率的H.264压缩标准,通过CPU内部集成的MFC模块实现对视频流的硬件压缩,在移植到系统的boa服务器上编写了CGI脚本响应远程客户端的响应.在客户端中,通过SDL和FFmpeg库提供的API接口完成了对经过网络传输到客户端上的视频数据的解码与播放,完成了包括视频的采集、编码、传输、显示各个功能模块的整个系统设计.
