基于visual studio 2017在Windows平台下编译FFmpeg

开始编译(前提是你前面已经配置好了编译环境)

编译ffmpeg，有两种方式，

微软官方Demo

可以按照微软官方的Demo教程来编译，先使用git下载，

git clone git://github.com/microsoft/FFmpegInterop.git
cd FFmpegInterop
git clone git://source.ffmpeg.org/ffmpeg.git

下载完成之后，目录结构如下：

FFmpegInterop\
    ffmpeg\              - ffmpeg source code from the latest release in git://github.com/FFmpeg/FFmpeg.git
    FFmpegInterop\       - FFmpegInterop WinRT component
    Samples\             - Sample Media Player applications in C++, C#, and JavaScript
    Tests\               - Unit tests for FFmpegInterop
    BuildFFmpeg.bat      - Helper script to build FFmpeg libraries as described in https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT
    FFmpegConfig.sh      - Internal script that contains FFmpeg configure options
    FFmpegWin8.1.sln     - Microsoft Visual Studio 2013 solution file for Windows 8.1 and Windows Phone 8.1 apps development
    FFmpegWin10.sln      - Microsoft Visual Studio 2015 solution file for Windows 10 apps development
    LICENSE
    README.md

直接在bash窗口中进入,执行执行编译相应版本的命令就行了

BuildFFmpeg.bat win10                     - Build for Windows 10 ARM, x64, and x86
BuildFFmpeg.bat phone8.1 ARM              - Build for Windows Phone 8.1 ARM only
BuildFFmpeg.bat win8.1 x86 x64            - Build for Windows 8.1 x86 and x64 only
BuildFFmpeg.bat phone8.1 win10 ARM        - Build for Windows 10 and Windows Phone 8.1 ARM only
BuildFFmpeg.bat win8.1 phone8.1 win10     - Build all architecture for all target platform

微软官方demo提供得是基于visual studio 2015的编译环境。如果你是visual studio 2017的话需要修改文件“BuildFFmpeg.bat”里面的路径。

下面示例是我修改的win10 x64

:Win10x64
if %BUILD.x64%==N goto Win10ARM
echo Building FFmpeg for Windows 10 apps x64...
echo:

setlocal
call "%VS150COMNTOOLS%..\..\VC\Auxiliary\Build\vcvarsall.bat" x64 store
set LIB=%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\lib\x64;%UniversalCRTSdkDir%lib\%UCRTVersion%\ucrt\x64;%UniversalCRTSdkDir%lib\%UCRTVersion%\um\x64;
set LIBPATH=%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\lib\x64;
set INCLUDE=%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\include;%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\atlmfc\include;%UniversalCRTSdkDir%Include\%UCRTVersion%\ucrt;%UniversalCRTSdkDir%Include\%UCRTVersion%\um;%UniversalCRTSdkDir%Include\%UCRTVersion%\shared;%UniversalCRTSdkDir%Include\%UCRTVersion%\winrt;
::下面三行是原来的
::set LIB=%VSINSTALLDIR%VC\lib\store\amd64;%VSINSTALLDIR%VC\atlmfc\lib\amd64;%UniversalCRTSdkDir%lib\%UCRTVersion%\ucrt\x64;;%UniversalCRTSdkDir%lib\%UCRTVersion%\um\x64;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6\lib\um\x64;;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6\Lib\um\x64
::set LIBPATH=%VSINSTALLDIR%VC\atlmfc\lib\amd64;%VSINSTALLDIR%VC\lib\amd64;
::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;

%MSYS2_BIN% --login -x %~dp0FFmpegConfig.sh Win10 x64
endlocal

忘了说了，记得现在环境变量里新建一个VS150COMNTOOLS，路径指向D:\Microsoft\Microsoft Visual Studio\2017\Enterprise\Common7\Tools，实际路径根据你安装的visual studio 2017的位置。
