Research And Implementation Of Monitoring System Based On Wifi Streaming

Video and image are carriers that can take vivid, intuitive description of the objective things.This is a vivid expression of the form,it is a very important carrier of messages.The technology of capture,transmission and play the real-time video’s date is very popular in modern net’s world.For example,video conferencing,distance education and real-time video surveillance and so on.Multimedia technology has generated thousands kinds of file format and data compression format.The technology of capture,transmission and play the real-time video’s date and the technology of multimedia has similar experience,and during what brings out a variety of different related technologies.With the development of the network technology and multimedia technology, acquisition and transmission of video data becomes more convenient and faster.This article uses wireless streaming media technology,design a system of video capture wireless transmission and playback that based on the ARM11+Linux.The system’s network environment is built through WIFI.Camera video data collection equipment of OV9650.Collection drive of V4L2.The data encoding uses the H.264standard.Data transmission using the RTP protocol.And FFmpeg and QT library are used for video player module design.This paper first introduces the development of embedded systems, the video capture standard and streaming wireless transmission technology, and the agreement.Then describes the process of system hardware and software platform in detail.At last,focuses on the acquisition, wireless transmission of the video module and player module works as well as the implementation steps.After the test, the system has been able to run stable.
