The Design And Implementation Of The Wireless Transmission System For H264Video Based On Android

As the intelligent mobile phone is widely used in people’s life, some dreams which people dare not to think in the past have come true. The development of science and technology is the important power of "China dream" undoubtedly, and the intelligent mobile phone also plays an important role undoubtedly in the development of science and technology. In the past few years, the ability of information processing of intelligent mobile phone and mobile network transmission rate increases dramatically. The intelligent mobile phone terminals which use mobile network for video transmission become the object of study that people favor. In this paper, a wireless video transmission system with high practicability have been designed and implemented.This paper first introduces the background and research status of this project. With the mainstream of intelligent mobile phone market, this paper adopts Android intelligent mobile phone as the video data collection terminal, and elaborated the Android system framework and the function characteristics of the latest version of the. In addition, this paper also do some research for the current technology of video coding and decoding,then choose the H.264video compression coding and analyses H.264technical details deeply. Because this paper program a simple platform using C#language for the play of video, the C#language and.NET Framework platform also have been introduced.In the design process, this paper adopt the MediaRecorder class of Android system to realize real-time video collection, and realize the acquisition of data stream using the LocalSocket class; through the analysis and extracting of SPS and PPS information in the Android collection terminal directly, the original H.264real-time video stream is obtained; according to the protocol of RTP/UDP it sent the video stream packing; it realizes the real-time video playback by the transplantation of VLC player and the conversation of SDP. Then a wireless transmission system for H.264video based on android is completed. Finally, through the actual test, the system is stable and easy to use. At the same time, because of low cost, the system can be used widely and meet the various requirements.
