  pacman -S yasm
  pacman -S make cmake
  pacman -S diffutils  # 比较工具
  pacman -S pkg-config # 库配置工具
  pacman -S git
  

• x264源码编译

• x264 (opens new window)

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

编译

• 为了保证环境可用，选择如下shell

• cd C:\msys64 修改msys2_shell.cmd

# 第三行添加
call "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary\Build\vcvarsall.bat"
# 修改
set MSYS2_PATH_TYPE=inherit

• 运行msys2_shell.cmd -mingw64

CC=cl ./configure --enable-shared  
Make -j4
Make install

• fdk-acc源码编译

• v2.0.1有Makefile.vc

git clone https://github.com/mstorsjo/fdk-aac.git

nmake -f Makefile.vc

nmake -f Makefile.vc prefix=.\install install

• 新版本利用cmake和visual studio

• x265

x265 (opens new window)

• 进入msys-cl运行 ./make-Makefiles.sh，注意要先将/user/bin/cmake.exe改名，目的是使用系统安装的cmake进行编译

• nmake install

• 注意修改x265.pc，指定路径

• 编译ffmpeg (opens new window)

CC=cl.exe ./configure --prefix=./install --toolchain=msvc --enable-shared --disable-programs --disable-ffplay --disable-ffmpeg --disable-ffprobe --enable-libx264 --enable-gpl --enable-libfdk-aac --enable-nonfree --enable-libx265

编译过程的错误可以在ffbuild/config.log查看
