FFmpeg是一套可以用来记录、转换数字音视频，并能将其转化为流的开源计算机程序。它包括了目前领先的音/视频编码库libavcodec等。
libavformat ：用于各种音视频封装格式的生成和解析，包括获取解码所需信息以生成解码上下文结构和读取音视频帧等功能；
libavcodec ：用于各种类型声音/图像编解码；
libavutil ：包含一些公共的工具函数；
libswscale ：用于视频场景比例缩放、色彩映射转换；
libpostproc：用于后期效果处理；
ffmpeg ：该项目提供的一个工具，可用于格式转换、解码或电视卡即时编码等；
ffsever ：一个 HTTP 多媒体即时广播串流服务器；
ffplay ：是一个简单的播放器，使用ffmpeg 库解析和解码，通过SDL显示；
编译方法1：
1、下载ffmpeg1.1.2
apt-get install subversion //安装svn,
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg //下载ffmpeg源代码，保存目录/home/parallels/Documents/ffmpeg/test/ffmpeg.
//output:Checked out revision 26402.
apt-get install git//安装git
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg //http://ffmpeg.org/download.html官方下载ffmpeg方法,Receiving objects: 100% (314377/314377), 77.14 MiB | 145//KiB/s, done..
//保存目录：//home/parallels/Documents/ffmpeg/test/test/ffmpeg
2、配置ffmpeg
2.1、./configure --enable-shared --prefix=/usr/local/ffmpeg //执行该命令，报如下的错误：yasm not found, use --disable-yasm for a crippled build
//解决方法：安装yasm
3、安装yasm
3.1、下载yasm
http://download.csdn.net/detail/reboot2009/4424607 //yasm是汇编编译器，因为ffmpeg中为了提高效率用到了汇编指令，比如MMX和SSE
3.2、配置yasm
./configure
注意：不要使用prefix指定安装路径什么的，否则后患无穷啊！
3.3、编译yasm
make
3.4、安装yasm
make install
