[Abstract]:With the rapid development of China's economy and the continuous improvement of people's living standards, people have put forward higher requirements for their own safety problems. The traditional monitoring system is faced with problems such as inflexibility, low efficiency, high maintenance cost, etc. The market is in urgent need of a kind of surveillance system with strong flexibility, stable performance, low maintenance cost, active analysis and early warning. The intelligent video surveillance system is a trend of the future development of video surveillance system. According to the market demand, the intelligent video surveillance system has attracted more and more people's attention, and the demand continues to rise. From a technical point of view, intelligent video surveillance will develop towards the direction of adapting to more complex and changeable scenarios, analyzing and identifying more abnormal behaviors. Intelligent video surveillance technology is a prospective research field, which contains not only great scientific research value but also huge commercial value. In the aspect of mobile intelligent terminal, the Android platform developed by Google has greatly promoted the development of mobile intelligent terminal. Because of its openness, it has brought the opportunity for the popularization of video surveillance system of smart phone. Therefore, the research and development of an intelligent video surveillance system based on Android platform has great practical significance and market prospect. The research contents and results of this paper are as follows: (1) the research status of intelligent monitoring system based on Android platform is analyzed, and the demand of intelligent monitoring system is summarized. It is necessary to study the intelligent monitoring system based on Android platform. (2) the system uses RTP/RTCP to realize the transmission and control of video data, and RSTP to realize the establishment and control of streaming media server and client session. Live555 streaming media server is used to transmit real-time video stream. (3) the existing H.264 RTP packet algorithm is analyzed, and its shortcomings are found and optimized. Improve the efficiency of packet. (4) introduce the existing congestion control algorithm in the video transmission module, and improve the stationary adaptive algorithm. The improved RTP stationary adaptive algorithm is used to control traffic congestion to ensure that a certain QoS, optimizes the buffer in the video receiving module. In order to reduce packet loss rate and delay. (5) FFmpeg multimedia decoding library is optimized and transplanted to Android platform. Video data decoding is realized by JNI technology. (6) calling the short message platform to send alarm message to the user, prompt the user to view the real-time alarm video in time, and realize the monitoring 24 hours a day. Through the above work, the intelligent video surveillance system based on Android platform is successfully realized. After testing, the system runs stably, the picture is clear and smooth, and the delay is small. The system greatly reduces the labor intensity of security personnel and the pressure of video storage, and realizes the real time monitoring 24 hours a day.
