基于Android平台流媒体播放器的研究与实现

摘要

The multimedia library of Android supports small video file formats and its encoding and decoding efficiency is relatively low. To solve the above problems, an implementation scheme of streaming media player is proposed and its implementation process is described in detail. This scheme is based on FFmpeg integration scheme which is a collection of recording and audio/video codec convert function. The proposed scheme is compiled and transplanted into the Android platform after being cut and optimized in the Linux environment, which can achieve the playing function of local video and remote monitoring of real-time video. The result shows that this Android player plays smoothly and occupies small memory, which can be embedded in other applications and have broad application prospects.%为了解决Android自身多媒体库支持的视频文件格式少、编解码效率相对较低的问题，提出一种流媒体播放器的实现方案，并详细阐述了其实现过程。该方案是基于集录制、转换音/视频编解码功能为一体的音视频流整合方案FFmpeg，通过在Linux环境下对其进行裁剪和优化，编译并移植到Android平台上，实现了本地视频以及远程实时视频监控的播放功能。实验结果表明，此Android流媒体播放器能实现流畅的播放，占内存小，可嵌入其它应用程序中，具有广泛的应用前景。
