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
