毕业设计（论文）题目：基于FFmpeg库的全格式视频播放器设计—文件格式解析器设计英文题目：Full-formatvideoplayerBasedonFFmpeglibrary—Designingfordemuxer专业：软件工程班级：081105学号：学生姓名：指导教师：二零壹壹年六月东华理工大学毕业论文（设计）摘要I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，播放器几乎不可缺少，于是各种播放器紧跟着发展起来。本文旨在通过通过FFmpeg库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。该播放器是以Linux系统为平台,C语言为开发语言，在Linux界面下，在音频解码方面对MP3解码器的算法进行了优化。视频解码则是利用FFMpeg解码库,同时借助简易直控媒体层(SDL,SimpleDirectmediaLayer)...更多进行视频播放器的设计。整个系统从操作简便、界面友好、灵活、实用、功能全面的要求出发，体现了该播放器的稳定性，拓展性，兼容性的特点。最重要的是该播放器基本支持所有格式的音视频，能实现一些比较少有格式的播放。该播放器可以实现支持播放：1.多媒体容器所有格式；2.视频编码所有格式；3.音频编码所有格式；因多媒体的快速发展，多媒体不再局限于常见那几种格式，而更多的更少有的格式正在运运而生，该播放器减少了应格式限制需要转换格式而产生的烦扰，相信该播放器会给用户带来新的体验和更多的便利。关键字播放器;C;FFmpeg;Linux;SDL;全格式;东华理工大学毕业设计（论文）AbstractIIAbstractAlongwiththecomputerandextensiveapplication,therapiddevelopmentofInternet,multimediatechnologyisdevelopingrapidly.AllkindsofaudiovideoresourcesareavailableovertheInternet,inPeople'sDailylife,almostindispensable,andvariousplayersfollowingthedeveloped.Inthispaper,thedevelopmentplatforminthe.netdevelopedonasimplevideoplayerprocess,understandplayers,therealizationofthefunctionofthedevelopmentofrelatedtechnicalmasteryplayer,atthesametimeusethesoftwareengineeringrelatedtheoryknowledge,understandthesoftwaredevelopmentmethodsandsteps.ThisplayerisLinuxsystemasaplatform,theClanguagefordevelopinglanguage,usingLinuxnextinterfacedesign,inaudiodecodingalgorithmofMP3decodersoptimized.VideodecodingisusingFFMpegdecodinglibrary,alsousingSimpledirectcontrolmediaLayer(Layer,SimpleDirectmediaSDL)...Morevideoplayeronthedesign.Fromtheentiresystemoperateandfriendlyinterface,flexible,practical,comprehensivefunctions,basedontherequirementsofthestabilityofthereflectedthisplayer,expanding,compatibilitycharacteristic.Themostimportantisthebasicsupportallformattheplayercanrealizesomecompareaudioplayback.FewformatThisplayercanrealizesupportplay:1.Multimediacontainersallformats;2.Videocodingallformats;3.Audiocodingallformats;Becauseoftherapiddevelopmentofmultimedia,multimediaisnolongerconfinedtocommonthatseveralformats,andmoremorerareformatareshippedluckandhealth,thisplayerreducedrestrictionsshallbeproducedformattrouble,believethattheplayerwillbringnewexperiencesandmoreconvenient.KeywordsPlayer;C;FFmpeg;Linux;SDL;Allformat东华理工大学毕业设计（论文）AbstractIII目录摘要........................................................................................................................................................I关键字........................................................................................................................................................IAbstract...................................................................................................................................................IIKeywords.................................................................................................................................................II第一章绪论.......................................................................................................................................11.1项目背景与意义.........................................................................................................................11.2市面流行播放器举例简介.........................................................................................................11.2.1暴风影音.........................................................................................................................11.2.2风雷影音.........................................................................................................................21.3几种常见格式简介.....................................................................................................................3第二章开发工具介绍...........................................................................................................................52.1C语言........................................................................................................................................52.2Linux操作系统........................................................................................................................52.3ffmpeg库..................................................................................................................................62.3.1ffmpeg简介..................................................................................................................62.3.2ffmpeg媒体文件处理...............................................................................................72.3.3ffmpeg文件解析库和编解码库..............................................................................72.4SDL...........................................................................................................................................7第三章系统需求分析...........................................................................................................................93.1用户的特点...................................................................................................................
