ffmpeg库编译安装及入门指南（Windows篇）

先为了提高下载速度，将下载源换成中科大的：

sed -i "s#mirror.msys2.org/#mirrors.ustc.edu.cn/msys2/#g" /etc/pacman.d/mirrorlist*
pacman -Sy

pacman -S mingw-w64-x86_64-toolchain  # mingw64编译工具链，win下的gcc
pacman -S base-devel    # 一些基本的编译工具
pacman -S yasm nasm     # 汇编器

git clone https://code.videolan.org/videolan/x264.git

build-x264.sh

#!/bin/sh
basepath=$(cd `dirname $0`;pwd)
echo ${basepath}

cd ${basepath}/x264-src   # 根据路径名称自行修改
pwd

./configure --prefix=${basepath}/x264_install --enable-shared
make -j8
make install

build-ffmpeg.sh

#!/bin/sh
basepath=$(cd `dirname $0`;pwd)
echo ${basepath}

cd ${basepath}/ffmpeg-5.1.2-src
pwd

export PKG_CONFIG_PATH=${PKG_CONFIG_PATH}:/d/repos/ffmpeg/x264_install/lib/pkgconfig
echo ${PKG_CONFIG_PATH}

./configure --prefix=${basepath}/ffmpeg_5.2.1_install \
--enable-gpl --enable-libx264 --disable-static --enable-shared \
--extra-cflags=-l${basepath}/x264_install/include --extra-ldflags=-L${basepath}/x264_install/lib

make -j8
make install
