摘要
多媒體的高速發展和廣泛普及給人們的生活帶來了翻天覆地的變化，而科技的進步帶來更多是人們對生活的享受，人們對于視聽效果的享受也要比以前的要求更高。從早期的幕布電影，發展到現在的高清晰數字影片，從以前的WMV、WMA等媒體格式發展到如今RMVB、RM、AVI等主流媒體格式，雖然一些較早的媒體格式依然沿用至今，但是隨著人們對多媒體質量的苛求，以及媒體文件大小的限制，這些媒體沙場上的老兵最終是會退隱江湖的。無可非議，如今我們已經進入了多媒體時代，很好的了解和掌握一些媒體知識對于處在現階段的朋友們會是很有幫助的。
多媒體以震撼的音效，細膩的畫質和逼真的動畫效果引起了人們的廣泛關注。音視頻技術不同地和其它技術相融合，逐漸改變了人們的生活和工作方式。Visual C++是進行多媒體底層開發的主要工具，雖然有其它開發語言，如Java等也可以進行開發，但是在實現速度以及靈活性方面，遠遠比不上Visual C++。更加重要的是，很多標準庫的代碼都是用C++或者C語言實現的。
我的播放器是用VC＋＋在windows XP平臺上基于MFC開發的，所使用的編程語言是C＋＋。面向對象的C＋＋在windows平臺上開發應用程序具有明顯的優勢，同時VC＋＋在界面開發和編譯調試上能提供強大的功能，并且實現高清視頻的播放。

Abstract
The multimedia high speed development and the widespread popularization have brought the earth-shaking change for people's life, but the technical progress brings much is the people to life enjoyment, the people enjoy regarding the seeing and hearing effect also must be higher than beforehand request. From the early theater curtain movie, develops the present high clear digital movie, from beforehand media form development and so on WMV, WMA until now mainstream media forms and so on RMVB, RM, AVI, although some early media form still continues to use until now, but along with the people to multimedia quality making excessive demands, as well as the media document size limit, in these media sandy plain veteran finally is can retire the rivers and lakes. Irreproachable, now we already entered the multimedia times, the very good understanding and grasps some media knowledge regarding to occupy the present stage friends to be able has the help very much.
Multimedia shocks the sound effect, the exquisite picture nature and the lifelike animation effect have aroused people's widespread interest.The sound video frequency technology differently and other technologies fuse, changed people's life and the working gradually.Visual C++ is carries on the multimedia first floor development the main tool, although has other development language, like Java and so on also may carry on the development, but in the realization speed as well as the flexible aspect, does not compare Visual C++ by far. Even more more importantly, the very many standard storehouse code all is realizes with C++ or the C language.
My player is with VC++ in windows in the XP platform based on the MFC development, the programming language which uses is C++.Object-oriented C++ develops the application procedure in the windows platform to have the obvious superiority, simultaneously VC++ can provide the formidable function in the contact surface development and the translation debugging, and realizes the high clear video frequency broadcast.
