Research on Audio and Video Transmission Strategy for Android

The Android operating system released by Google provides MediaRecoder and MediaPlayer objects for application-layer developers to develop audio and video applications.However,these objects can only be used in recording and playing but cannot be applied in streaming video and audio based on camera and microphone.Hence,after in-depth study of Android operating system,an efficient and flexible audio and video transmission strategy is proposed in this paper.Then,a third-party libavstream component is designed according to this strategy.Finally,an app based on libavstream called BLife is developed to test the availability and effectiveness of this strategy.
