    How to use the power analysis types of Intel® VTune™ Amplifier XE 2013 on Linux

    Background

    It is becoming increasingly important for software developers to become more power aware. A laptop or a mobile device would have limited use if it was not able to function for extended periods of time on battery alone. It is also critical for software to not be wasteful in their power usage. Intel® VTune™ Amplifier XE 2013 presents a software based solution whereby you can measure where your application is not optimal in its usage of power.

    • 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，介绍了如何移植FFMPEG到x86的android平台上。
