Design and Implementation of Video Player
Abstract: This thesis aims to develop a simple video player in the .net platform by understanding the player’s functions implementations and mastering the player development technologies, and uses the theory of software engineering to learn and understand the methods and steps of software develop. First of all, this thesis introduces some popular players in brief on the market, such as storm video, and some functions of these players, all kinds of special coding format file, then analyzes the advantages and disadvantages of various coding formats; secondly a simple, practical and convenient player is implemented with C# language on the .net platform. The following aspects are included: the development platform and technology of developing this player; functional module; function design; function realization, etc. Finally, the software development process is briefly summarized and my experience and feelings are also described.
