| Today’s society increasingly fast pace of life, with the mobile device hardware technology becomes more advanced, people mobile devices are increasingly high requirements from the previous pursuit of technological capabilities, and now the pursuit of visual operating system, the mobile phone operating system is also gradually increase the requirement. Android system is based on the Linux platform, open-source mobile operating system, the name of the platform by the operating system, middleware, user interface and application software, which claims to be the first mobile terminal to create a truly open and complete mobile software. Commonly used in mobile phones, PDA, tablet PCs, and a variety of information terminals. In this thesis, video player uses the Android open source technology, the use of the Java language and Eclipse editing tools for the preparation of the mediaplayer. At the same time gives a detailed system design process, part of the interface diagram and flowchart of the main module contact, this paper also encountered problems and solutions were discussed in detail, the multimedia player set play, pause, fast forward, fast retirement and other functions, good performance in the Android system can operate independently.3GP, MPEG4video format, not only for a certain bit rate of the video, audio encoding, and more emphasis on interactivity and multimedia system flexibility. It uses a very narrow bandwidth, through the frame reconstruction techniques, compression and transmission of data, in order to get the least amount of data the best image quality. Since the player is limited to application layer discussion, so the specific compression algorithm does not get to the bottom. |
