FFmpeg编译ARM文件供UWP项目使用
为了编译FFmpeg吃了不少亏,掉了不少坑.此处把正确编译过程写下
准备 git clone git://github.com/microsoft/FFmpegInterop.git cd FFmpegInterop git clone git://source.ffmpeg.org/ffmpeg.git
参考https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT 下载 MSYS2 YASM gas-preprocessor.pl
开始:
自行查看msys2安装教程.此处不赘述
msys2安装好后,修改目录下的msys2_shell.cmd 添加set MSYS2_PATH_TYPE=inherit这句话可继承上级环境
找到FFmpegInterop根目录下BuildFFmpeg.bat 添加以下两句话 set SET_FULL_PATH=1 set MSYS2_BIN="C:\msys64\usr\bin\bash.exe"
管理员运行 VS2015 x86 ARM Cross Tools Command Prompt/VS2015 x86 ARM 兼容工具命令提示符
执行以下命令
SET LIB=%VSINSTALLDIR%VC\lib\store\ARM;%VSINSTALLDIR%VC\atlmfc\lib\ARM;%UniversalCRTSdkDir%lib%UCRTVersion%\ucrt\arm;;%UniversalCRTSdkDir%lib%UCRTVersion%\um\arm;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6\lib\um\arm;;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6\Lib\um\arm SET LIBPATH=%VSINSTALLDIR%VC\atlmfc\lib\ARM;%VSINSTALLDIR%VC\lib\ARM; SET INCLUDE=%VSINSTALLDIR%VC\include;%VSINSTALLDIR%VC\atlmfc\include;%UniversalCRTSdkDir%Include%UCRTVersion%\ucrt;%UniversalCRTSdkDir%Include%UCRTVersion%\um;%UniversalCRTSdkDir%Include%UCRTVersion%\shared;%UniversalCRTSdkDir%Include%UCRTVersion%\winrt;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6\Include\um;
cd到FFmpegInterop目录 BuildFFmpeg.bat phone8.1 win10 ARM 等待执行完毕
