| Abstract: | YouTube is a Famous Video Web Site of the world.To provide service of the high quality video to upload,browse and share for users.In this paper,on the basis of mobile streaming media service specification,design the system architecture of YouTube media player of client.According to the functional design of the player,divided into the HTTP engine,audio and video buffer,audio and video decoding,audio and video synchronization,adaptive and Ul interface module.On the basic of comparison and analysis of mobile streaming media transmission protocol,it studies the implementation scheme of using the HTTP protocol to optimize the network engine.Using H.264 decoder to optimize the transmission data from the algorithm and code level,realize the function of the media player play the video from YouTube video web site. |
