The architecture design of streaming media applications for Android OS

In view of the imperfection of the Android operating system multimedia function and the complexity of streaming media system. At the same time, the development cycle is long, and efficiency is low. In order to solve those problems, the thesis designed the streaming engine layer between Linux kernel layer and application framework layer of Android platform, and constructed fast and convenient streaming media application development framework. First of all, Android operating system (OS) was analyzed, and then the media engine was added into the Android OS architecture. Based on the characteristic of the streaming media system, the steaming media engine is divided into five layers, including the user interface, data capture, and data output, codec, and network transmission layer. At last, the architecture was applied in the wisdom medical terminal project. Through an instance of video data transmission client, the feasibility of the architecture is confirmed.
