Dependencies for MIDIVisualizer

This repository is used for the automatic deployement of MIDIVisualizer.
Large binary dependencies are stored as artifacts of a release.
The repository itself contains the configurations used to generate these binaries.

Current dependencies:

  • FFMPEG, static, LGPL2-only

Instructions

FFMPEG

FFMPEG is built as a set of static libraries using vcpkg on Windows, macOS and Ubuntu, with modified settings. We generate the LGPL2 version of the library with hardware encoders from Intel and Nvidia disabled, and with no debug symboles. The generated FindFFMPEG.cmake is designed specifically for use in MIDIVisualizer.

  • Install yasm:
    • Windows: TBA
    • macOS: use Homebrew with brew install yasm
    • Ubuntu: use sudo apt-get install yasm
  • Install vcpkg by cloning https://github.com/microsoft/vcpkg.git (commit used: f4bd64233ae875b6b3315fe4fab279335a6adf2b).
  • Install the recommended dependencies and setup vcpkg by running vcpkg/bootstrap-vcpkg.{sh, bat}.
  • Replace the content of vcpkg/ports/ffmpeg by the content from the ffmpeg directory in this repository.
  • For macOS, add the file x64-osx-10-12.cmake from this repository to the vcpkg/triplets/ directory.
  • Build FFMPEG has a set of static libraries for a 64 bits platform:
    • Windows: vcpkg install ffmpeg:x64-windows-static
    • macOS: vcpkg install ffmpeg:x64-osx-10-12
    • Ubuntu: vcpkg install ffmpeg:x64-linux
  • Export the generated libraries and headers:
    • Windows: vcpkg export ffmpeg:x64-windows-static --raw
    • macOS: vcpkg export ffmpeg:x64-osx-10-12 --raw
    • Ubuntu: vcpkg export ffmpeg:x64-linux --raw
  • This will put the generate package in vcpkg-export-....
  • Copy vcpkg-export-.../installed/x64-.../{include, lib, share} to a ffmpeg directory.
  • Zip the directory, using the following output name:
    • Windows: ffmpeg-windows-64-static-lgpl.zip
    • macOS: ffmpeg-osx-64-static-lgpl.zip
    • Ubuntu : ffmpeg-ubuntu20-64-static-lgpl.zip or ffmpeg-ubuntu18-64-static-lgpl.zip depending on the version
  • Upload these files in a release on this repository.
