Windows下编译ffmpeg

资料准备

1. msys2安装包
2. ffmpeg源码
3. x264源码

安装MSYS2

1. 运行msys2，在命令框中安装mingw工具包和nasm（汇编工具）

pacman -S mingw-w64-x86_64-toolchain

pacman -S base-devel

pacman -S nasm

2. 进入路径~/MSYS2/home/‘username’/

编译x264和ffmpeg

执行下段代码，建议写入一个脚本中直接执行即可(~/MSYS2/home/‘username’/目录下)

basepath=$(cd `dirname $0`;pwd)

echo ${basepath}


cd ${basepath}/x264-master
pwd

./configure --prefix=${basepath}/x264_install --enable-static --enable-shared
make
make install

cd ${basepath}/ffmpeg
pwd

./configure --prefix=${basepath}/ffmpeg_install \
--enable-static --enable-shared --enable-libx264 --enable-gpl \
--extra-cflags=-I${basepath}/x264_install/include \
--extra-ldflags=-L${basepath}/x264_install/lib 

make
make install

配置环境变量
