今天是建党节，习总书记指出，党的建设要以“照镜子、正衣冠、洗洗澡、治治病”为总要求。希望我们的党越来越纯洁，为人民谋福利。
言归正传，每次项目中需要编译相应的ffmpeg，都很费时费力。这次记录下全过程，以便下次使用。
windows下使用msys编译比较麻烦，而且由于安装了很多开源库，导致系统变量很复杂，容易出错。
本次选择在ubuntu下使用zeranoe的脚本交叉编译，windows下使用的ffmpeg动态库。
环境：ubuntu 13.04，vmware 8.0.2 build-591240
ubuntu是在官网下载了镜像文件，通过vmware虚拟机安装后，没有更新直接使用。
主要工具以及版本号：
gcc 3.7.4
make 3.8.1
cmake 2.8.10.1
automake 1.11.6
yasm 1.2.0
makeinfo 4.13
curl 7.29.0
pkg-config 0.26
audoconf 2.69
libtool 2.4.2
flex 2.5.35
bison 2.5
明确需求：本次项目中需要ffmpeg帮助编解码，要求编译第三方的libaacplus和libx264.生成动态库，尽可能小，以便于软件打包。
1. 首先下载 cross_compile_ffmpeg.sh ,本次下载的git上一个月以前更新的。
地址在 https://github.com/rdp/ffmpeg-windows-build-helpers
如果网络允许的话，可以直接运行
a> $ wget https://raw.github.com/rdp/ffmpeg-windows-build-helpers/master/cross_compile_ffmpeg.sh -O cross_compile_ffmpeg.sh
b> $ chmod u+x cross_compile_ffmpeg.sh
c> $ ./cross_compile_ffmpeg.sh
但是这种方法，往往会提示https……失败，换http或者git都失败。还是老老实实地下载了吧。
2. 下载下来的 cross_compile_ffmpeg.sh 放到主目录下cross_compile_ffmpeg文件夹里。
我的目录结构是这样的 /home/gong/cross_compile_ffmpeg/cross_compile_ffmpeg.sh
3. 更改 cross_compile_ffmpeg.sh 的属性，使其可以执行。并执行它。
$ chmod u+x cross_compile_ffmpeg.sh
$ ./cross_compile_ffmpeg.sh
如果提示某些命令没有安装，例如 'curl' 'pkg-config' 'make' 'git' 'svn' 'cmake' 'gcc' 'autoconf' 'libtool' 'automake' 'yasm' 'cvs' 'flex' 'bison' 'makeinfo'
中的某一个。直接 sudo apt-get install xxx 对应安装即可。
4. 一般来说上一步执行肯定会出错，但是会在 cross_compile_ffmpeg文件夹里生成一个sandbox的文件夹，这个文件夹里面有一个名为 mingw-w64-build-3.2.0 的文件(cross_compile_ffmpeg.sh里有下载该文件的语句)。
会在脚本里被执行，下载安装我们本次编译需要的工具。我看到官网http://ffmpeg.zeranoe.com/blog/ 已经更新到 mingw-w64-build-3.2.3 了。但是 cross_compile_ffmpeg.sh 脚本里还是指定的是3.2.0版本。
工具编译完成后，生成在路径/home/gong/cross_compile_ffmpeg/sandbox/mingw-w64-i686/i686-w64-mingw32/bin 下。
5. 按照本次项目需求，更改脚本，中间会经历千万曲折，反复修改编译选项。最终脚本如下
#!/usr/bin/env bash

Welcome to the ffmpeg cross-compile builder-helper script.
Downloads and builds will be installed to directories within $cur_dir
If this is not ok, then exit now, and cd to the directory where you'd
like them installed, then run this script again from there.
NB that once you build your compilers, you can no longer rename/move
the sandbox directory, since it will have some hard coded paths in there.
You can, of course, rebuild ffmpeg from within it, etc.

针对编译X264和aacplus遇到的错误，参考http://www.cnblogs.com/zzugyl/archive/2013/01/31/2887304.html 和 http://www.cnblogs.com/zzugyl/p/3163261.html
6. 重新执行，就会成功。
$ ./cross_compile_ffmpeg.sh
最后生成的结果并没有按照bin include lib文件夹分开，而是各自在各自的文件夹里。
例如本次生成的是动态库，所以目录是在/home/gong/cross_compile_ffmpeg/sandbox/bin/ffmpeg-git-shared/
avcodec-55.dll和avcodec.lib在libavcodec/下。并且avcodec-55.dll只有2.2M。
关于windows下调用的inlcude路径，确实是个问题。自己在这个目录下总结头文件。我是按照http://ffmpeg.zeranoe.com/builds/ 他编译的结果对应找的头文件。需要对应版本号，不然不一定一样。还有一个方法是，在windows下虽然编译失败，但是编译ffmpeg的结果还是有include bin 和 lib 文件夹的，把include文件夹拷过来就可以了。同样，注意统一版本号。
