摘    要

随着计算机的广泛运用，Internet的迅速发展，多媒体技术也是迅速发展。各种音频视频资源在网上随处可见，在人们的日常生活中，几乎不可或缺，于是各种播放器紧跟着发展起来。本文旨在通过在.net开发平台上开发一个简单的视频播放器的过程，了解播放器的功能实现，掌握播放器开发的相关技术，同时利用软件工程的相关理论知识，了解软件开发的方法与步骤。

首先，本文简单介绍下市场上流行的播放器，比如暴风影音等，然后了解这些播放器的功能，还有各种播放器播放的特别编码格式文件，分析各种编码格式的优缺点；其次选择在微软的.net开发平台上使用C#语言进行开发，编写出功能简单实用方便的播放器。主要包括以下几个方面：开发本软件所使用的开发平台与技术；功能模块；功能设计；功能实现等。最后，对本软件的开发过程进行简要总结，并介绍一下本人的体会和感想。

Design and implementation of video player

Abstract

Along with the computers are widely used, Internet rapid development and the multimedia technology is also developing rapidly. A variety of audio and video resources can be seen everywhere on the Internet, in people’s daily lives, almost indispensable, then all kinds of Player is developed. This paper aim at to understand the functions implementations of Player, to master the development technologies of Player, and use the theory of software engineering to understand the method and step of software develop, by means of the process to develop a simple video player in the development platform of .Net.

First of all, this paper introduce some popular players in brief on the market, such as storm video, etc., then to understand some functons of these players, all kinds of special coding format file they can play, to analyze the advantages and disadvantages of various coding formats; second I choose Microsoft .Net development platform and use the C # language to write a function of simple and practical and convenient player. Includeing the following main aspects: the development platform and technology of to develop this player; functional module; function design; function realization, etc. Finally, a brief summary of the software development process and some my experience and feelings are described.
