Research on Video Rendering on Android

Nowadays there are more and more people using Android related devices. Efficient multimedia players are highly required. Video-audio rendering plays an important role in multimedia players, which is also relates with the platform. It´s known to all that Android has many versions, and one app can hardly support all versions. So in this paper, We introduce four methods of video rendering by using JNI(Java Native Interface), and present the process of implementation. Finally, we compare those methods and get a more efficient video-audio rendering way. According to the most efficient rendering way, we will develop android apps for video meeting and surveillance system.
