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,...

Programming for Multicore and Many-core Products including Intel® Xeon® processors and Intel® Xeon Phi™ X100 Product Family coprocessors

The programming models in use today, used for multicore processors every day, are available for many-core coprocessors as well. Therefore, explaining how to program both Intel Xeon processors and Intel Xeon Phi coprocessor is best done by explaining the options for parallel programming. This paper provides the foundation for understanding how multicore processors and many-core coprocessors are...
