摘要: 针对将音视频交互技术应用在线视频教学的实验尚不完善的问题, 借助Android 平台对WiFi(Wireless Fidelity)进行一对一(Ad-Hoc 模式)的网络连接实验。通过对基于FFmpeg 的H. 264 视频编解码和Speex 音频源码以及相应API(Application Programming Interface)的分析, 实现了两Android 系统间的音视频同步传输。实验给出了整体设计方案, 进行了编程调试, 验证了系统架构, 通信协议以及核心算法的可行性, 实现了两Android平台间的实时音视频交互, 视频和音频质量以及传输速率都达到了预期的目标。

关键词: Speex 技术, Android 系统, FFmpeg 编解码, H. 264 编码

Abstract: The mobile terminal equipment is more and more developed, the interactive application of audio and video information is increasingly widespread, but it is not perfect to use online video teaching. A Ad-Hoc network is connected to a Fideliy Android by means of FFmpeg, and the audio and video synchronization transmission between two Android system is realized by analyzing the H. 264 video codec and Speex. The whole scheme is given, the program is debugged, the system architecture, communication protocol and core algorithm are verified. Through the experiment, we can realize the real-time audio and video interaction between the two Android platform, the video and audio quality and transmission rate have reached the expected target.

Key words: Android system, H. 264 encoding, FFmpeg encoding and decoding, Speex technology
