到官网上下载新版的ffmpeg 0.6.1 :http://www./releases/ffmpeg-0.6.1.tar.bz2
我当时下载mingw安装时是完全在线安装，在mingw目录下会有msys
我mingw装在c:/mingw 下，msys在c:/mingw /msys
编译ffmpeg 还需要SDL 地址：http://www./release/SDL-1.2.14.tar.gz
解压该软件包；
将lib下的所有文件复制到C:/mingw/lib；
将include下的所有文件复制到C:/mingw/include；
将bin下的i386-mingw32msvc-sdl-config复制到C:/mingw/bin，并重命名为sdl-config；
将bin下的SDL.dll复制到C:/mingw/bin中。
并找到sdl的源码包，将其中的include文件复制到C:/mingw/include中
（因为ffmpeg例子依赖其头文件）
解压ffmpeg-0.6.1.tar.bz2，复制到盘，c:/ffmpeg-0.6.1 (此文件夹中就有configure等文件了)
打开msys/1.0/etc中的文件fstab 增加一行：C:/ffmpeg-0.6.1
接着运行：msys.bat文件，启动了命令行界面：
切换到cd C:/ffmpeg-0.6.1
接着输入命令：
./configure --enable-memalign-hack
可能不妙，会出现configure: line ***: pr: command not found 的问题。
这样，我们还需要下载coreutils 下载地址:http://ftp./gnu/coreutils/
安装coreutils 打开其安装目录，复制其bin文件夹中的pr.exe ,libintl3.dll,libiconv2.dll 这三个文件到mingw/bin中，OK
用msys.bat重启命令行界面，
输入:
./configure --enable-memalign-hack --enable-shared
通过了，
之后，
make
之后
make install
完工。
得到的文件在msys/1.0/local中
其中的bin中有
ffmpeg.exe
ffprobe.exe (ffmpeg-0.6.1中有4个可执行文件)
include文件夹中包含
libavcodec
libavdevice
libavformat
libavutil
libswscale
5个文件夹
lib中有上面对应的5个.a静态库文件
总共49.5M
--------------------------------
生成vc环境下可用的dll，lib库文件
在msys.bat中加入下面语句：
call "D:/Program Files/Microsoft Visual Studio 9.0/VC/bin/VCVARS32.BAT"
（自己给出相应路径）
msys.bat启动，输入命令：
./configure --enable-shared --disable-static --enable-memalign-hack
make
make install
生成的dll,lib在msys/1.0/local中
