2、x264

1) 下载源码

git clone http://git.videolan.org/git/x264.git

或者 

wget ftp://ftp.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20120528-2245-stable.tar.bz2

tar xvf x264-snapshot-20120528-2245-stable.tar.bz2

2) 配置，编译，安装

./configure --enable-static --enable-shared --enable-pic

make

sudo make install

生成文件在/usr/local/lib中，有libx264.a，libx264.so，libx264.so.159
