毕业设计（论文）I 摘要在多媒体技术高速发展的今天，多媒体播放器出现了多种缺点和毛病，主要表现在内存大量占用和操作复杂繁琐方面。
本文针对当今流行视频播放器的优缺点进行了研究，然后在此基础上进行综合和总结，开发出了一个功能丰富和操作简易的视频播放器，该播放器具有低内存占用和绿色无广告的特点，因此具有广阔的市场前景。
本视频播放器是基于脚本语言ActionScript3.0，利用Adobe Adobe Flash Flash Flash CS4CS4设计开发完成。
Flash Flash CS4CS4是一种功能非常强大的工具，可以将视频添加到基于Web 的应用程序中。
Flash 的FL V 和F4V 视频格式具备技术和创意优势，允许将视频、数据、图形、声音和交互式控制融为一体。
结合ActionScript 3.0 的脚本绘图技术以及数组技术，的脚本绘图技术以及数组技术，可以方便地制作出媲美专业水平的视频播可以方便地制作出媲美专业水平的视频播放器。
本次设计就将利用Flash Flash CS4CS4制作一个可以进行列表选择、音量控制、进度控制的视频播放器。
本次设计主要利用Actionscript3.0作为后台逻辑处理和功能实现，文中对视频播放器做了详细的需求分析，并详细介绍了视频播放器的总体设计，包括视频播放器的架构设计、功能模块的划分、视频播放列表文件的设计、常用工具的设计、本地数据存储设计等，然后具体介绍了以上各个部分和功能的具体实现原理和过程，最后再对该视频播放器进行测试，没有重大的异常和错误，证明其设计方案的可行性和正确性。

As sustained rapid development in multimedia technology, a variety of shortcomings and faults are emerged in multimedia player, mainly in the occupation of memory and the complication of the operation. This article analyze the advantages and disadvantages of the current popular multimedia player then developed a video player with low memory footprint and without advertisements based on this, so it will get a broad market prospects. prospects. The The The video video video on on on demand demand demand system system system is is is based based based on on on the the the scripting scripting scripting language language language ActionScript ActionScript ActionScript 3.0, 3.0, design and development with Adobe Flash CS4 completed. Flash CS4 is a very powerful tool, you you can can can add add add video video video to to to a a a Web-based Web-based Web-based application. application. application. Flash Flash Flash to to to FL V FL V and and and F4V F4V F4V video video video formats formats formats with with technical technical and and and creative creative creative advantages, advantages, advantages, allows allows allows video, video, video, data, data, data, graphics, graphics, graphics, sound, sound, sound, and and and interactive interactive interactive control control integration. Combined Combined with with with ActionScript ActionScript ActionScript 3.0 3.0 3.0 scripting scripting scripting graphics graphics graphics technology technology technology and and and an an an array array array of of technology, you can easily produce professional level comparable video player. The design will use use Adobe Adobe Adobe Flash Flash Flash CS4 CS4 CS4 can can can produce produce produce a a a list list list of of of selection, selection, selection, volume volume volume control, control, control, schedule schedule schedule control control control of of of the the video player. Actionscript3.0 is main used to handle the logic and to realize the function, then a detailed requirement analysis is make and introduces the general design of the video player. Include the architecture design, the functional modules divided, the design of video play list file, the design of tools, the local data storage design and so on, and then introduced the specific implementation principle and process of the above every part and function. In this paper, the design of the music on-demand system is tested by the black box and white box, no major anomalies and errors, to prove the feasibility and correctness of its design.
