Design And Implementation Of Video Player

With the rapid development of Internet,people's demand for multimedia information network has also changed-from a single change to the complex.Multimedia video player also will be popular.Current common multimedia video player each have their own characteristics,but their basic functions is basically same.A lot of players the function is all ready,but the complex operation,and take up memory space is big,this paper mainly aimed at the problem to design a simple operation,function can meet the demand of most multimedia video player.The works of the paper are as follow:(1)This paper introduces the research meaning and purpose and the status of recent video player's development.In view of the complicated operation,large memory space such as faults,design a simple operation and meet the demand of most of the play of multimedia software.(2)This paper analyzes the player requirement,then based the requirements to analyze the player process and data process,at last set up the development environment.This paper shows the effect of part function and the effect of play audio and video files.This paper mainly describes the outline design of the multimedia player,then finish the division and module partition of software,the hierarchical structure of the software logic diagram and software design.After design,the code implementation of main functions have been finished in detail,and this paper shows the main part of the function code.Finally,we discuss the image scaling algorithm.(3)The software realize the conventional playback supporting for playback of common file format.A novel button has been added,the user through the click of a button can be set to start playing and playback end time,the user also can experience the further enhance.(4)System test the multimedia player that can support common format file,for example mp3,mp4,avi,regular broadcast suspend normal functions,such as the user set the start playing time and end time.The player automatically jump to the corresponding time to play,to the end of the end point,development shows that the software has reached the expected purpose.The multimedia player is designed in Windows XP operating system and Visual C++ 6.0.In programming,development,we use the Microsoft ActiveX controls-visual animation ActiveMovie control,program debugging and running,through preliminary realized media player software development capabilities.Based on Visual studio 2008 and MFC integrated development environment,we use MCI command interface to programming of the system implementation.
