Android ffmpeg的x86编译和优化

Android内置的编解码器比较少,流媒体功能也比较薄弱,现有的android关于远程视频的程序大部分使用了FFMPEG。FFmpeg是一个开源免费跨平台的视频和音频流方案,属于自由软件,采用LGPL或GPL许可证(依据你选择的组件)。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec,为了保证高可移植性和编解码质量,libavcodec里很多codec都是从头开发的。FFmpeg支持MPEG、DivX、MPEG4、AC3、DV、FLV等40多种编码,AVI、MPEG、OGG、Matroska、ASF等90多种解码.TCPMP, VLC, MPlayer等开源播放器都用到了FFmpeg。这些播放器也大部分移植到了Android 上,只是都是基于ARM的,本文基于目前流行的2个开源项目,...
