OBS-MIDI can be built and installed on windows, Mac, and Linux

Prerequisites

You’ll need Qt 5.15.2, CMake and a working OBS Studio development environment installed on your computer.

Windows

Once you have successfully built OBS Studio, in the obs-studio source directory

Go into the {obs-studio}/plugins
git clone --recursive git@github.com:cpyarger/obs-midi.git
open {obs-studio}/source/CMakeLists.txt
append add_subdirectory(obs-midi) to the end of the file
rerun cmake-gui configure, generate
in cmake-gui you will need to set a few variables
- (path)LIBOBS_INCLUDE_DIR = {obs-studio}/libobs
- (filepath)LIBOBS_LIB = {obs-studio-build}/libobs/Debug/obs.lib
- (path)QTDIR = C:\Qt\5.15.2\msvc2019_64
- (boolean)isCI = true
- (filepath)OBS_FRONTEND_LIB = {obs-studio-build}/UI/obs-frontend-api/Debug/obs-frontend-api.lib
in cmake-gui configure, generate, and open project

Now you should be good to edit things

Linux

On Debian/Ubuntu :

sudo apt-get install libboost-all-dev
git clone --recursive git@github.com:cpyarger/obs-midi.git
cd obs-midi
mkdir build && cd build
cmake -DLIBOBS_INCLUDE_DIR="<path to the libobs sub-folder in obs-studio's source code>" -DCMAKE_INSTALL_PREFIX=/usr -DUSE_UBUNTU_FIX=true ..
make -j4
sudo make install

On other linux OS’s, use this cmake command instead:

git clone --recursive git@github.com:cpyarger/obs-midi.git
cd obs-midi
mkdir build && cd build
cmake -DLIBOBS_INCLUDE_DIR="<path to the libobs sub-folder in obs-studio's source code>" -DCMAKE_INSTALL_PREFIX=/usr ..
make -j4
sudo make install

OS X

As a prerequisite, you will need Xcode for your current OSX version, the Xcode command line tools, and Homebrew. Homebrew’s setup will guide you in getting your system set up, you should be good to go once Homebrew is successfully up and running.

Use of the macOS CI scripts is recommended. Please note that these scripts install new software and can change several settings on your system. An existing obs-studio development environment is not required, as install-build-obs-macos.sh will install it for you. If you already have a working obs-studio development environment and have built obs-studio, you can skip that script.

Of course, you’re encouraged to dig through the contents of these scripts to look for issues or specificities.

git clone --recursive git@github.com:cpyarger/obs-midi.git
cd obs-midi
./CI/install-dependencies-macos.sh
./CI/install-build-obs-macos.sh
./CI/build-macos.sh
./CI/package-macos.sh

This will result in a ready-to-use obs-midi.pkg installer in the release subfolder.
