摘要
视频监控系统对视频压缩率和编码实时性具有很高的要求,X264算法的高压缩率和TMS320DM6467处理器的高性能正好满足这2个需求。利用Linux操作系统的V4L2编写视频采集程序,经X264算法压缩算法对采集到的视频流进行压缩编码后,通过ppp拨号的方式由3G网络完成传输。实验表明:对捕获的视频帧编码效果良好,满足监控系统需求。
High compression ratio and real time encoding feature are neccessary for video surveillance system.The high compression ratio of X264 algorithm and the excellent performance of DM6467 processor meet both requirements exactly.The system capture video by V4L2 video capture program of the Linux operating system.The video streams are compressed by the X264 algorithm.The compressed encode datas are transmitted in 3G network by ppp dial-up.The experimental results show that the encoding effect of captured video frame are very well,and can meet the needs of surveillance system.
