Real-time Audio And Video Transmission System Based On Android Platform And Wireless Network

With the rapid development of information technology, the transmission technology of the audio and video based on embedded system and network, has become mature and widely used.So are the Linux open-kernel-based Android mobile operating system and applications based on wireless network. Thus the wireless audio and video transmission system based on the Android mobile phone development system and network application come into view.This paper introduced the wireless audio and video transmission technology and research status, the system framework of the Android mobile development platform, and relevant concepts, such as the Java Native Interface (JNI), the Android NDK, Fast Forward mpeg (FFmpeg,the audio and video processing solutions) and Streaming Media Transfer Protocol as well.After analysis of the working principle of the wireless audio and video transmission system, this paper presents the design of the wireless audio and video transmission system based on the Android mobile development platform.The design transplant the FFmepg audio and video solutions to the Android platform as the codec library of audio and video data.It applies the Android APIs.Besides, the paper analyzes and explains other technologies used in the system implementation process.The paper implemented the wireless audio and video transmission system based on the Android platform. Compared with the traditional audio and video network communication system, it has advantages such as wireless, lower cost and greater availability.It can be applied in home security monitoring and instant messaging of network terminals.
