ffmpeg-msvc-build

Scripts for building FFmpeg with MSVC on AppVeyor.

The script closely follows the official instructions. By default, only static LGPL builds are generated (in 32 and 64 bit, and in debug and release configurations). However, the build matrix can be easily modified to allow different configurations to be built as well.

Requirements

• NASM
• MSYS2 (needs to be installed at C:\msys64\)
• [Build Tools for Visual Studio] (https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16#) (make sure to check C++ build tools)
• Nuget.exe
• The following packages installed with msys pacman pacman -S p7zip diffutils make nasm

Build

Prebuilt static LGPL builds with Visual Studio 2017 (toolset v141) can be found here. If you want to build your own version on your local machine, then:

• Checkout the tag for the ffmpeg version you want in the submodule
  • git submodule init
  • git submodule update
  • cd ffmpeg
  • git checkout n4.1.3 - replace the tag with whatever release you would like to build
• Ensure nasm is in your path; if not, add it see above pacman command.
• The following variables will be set in build.bat:
  • PLATFORM (x86, x64)
  • CONFIGURATION (Release, Debug)
  • LINKAGE (shared, static)
  • RUNTIME_LIBRARY (MD, MT)
  • LICENSE (LGPL21, LGPL3, GPL2, GPL3)
• Start the build script by running build.bat.

Package

• Update FFmpeg.LGPL.x86.nuspec version number to match ffmpeg (git checkout command above). If the license has changed, update that as well.
• nuget.exe pack FFmpeg.LGPL.x86.nuspec
• Upload resulting nupkg to trafficlandit nuget repo

License

All scripts for creating the builds are licensed under the conditions of the MIT license. For the examples in the examples folder, see individual files for license details.

The builds themselves are covered by the relevant license for your build (see here for full details).
