These resources look very ordinary, but gradually became an essential part of people’s daily life. Thereafter，verious players were developed. But many designers pursue only the fashionable appearance and versatile functions on players’ design. Hence resources’ waste was caused. For example, CPU and Memory are excessively taken. When users need the multi-task operation, it will bring much more trouble. But regarding the majority average users, many functions are not necessary. Against the shortcomings, a multilingual audio and video player is developed which remain the commonly used functions and optimize the performance. Common users can be satisfied for listening music and watching film. Except for the common form of vocal video files, the RM and RMVB form video files can be played on the player. In addition, these documents can be played in Chinese, Japanese and English. This graduation project primary mission: Firstly， various popular players are studied such as MEDIAPLAYER, REAL ONE and so on
