This Swift application installs the streamlabs/obs-studio mac virtual camera system extension on the user's system.
CMake (minimum 3.22) and xcode 15.2
Make sure you define the APPLE_TEAM_ID environment variable which is required because the build scripts will download the slobs-mac-virtual camera system extension and codesign it.
Run the following commands below (or just run build.sh script):
cmake --preset macos
cmake --build build --preset macos
The scripts will build RelWithDebInfo and pack the camera extension inside the app bundle.
By default, if no arguments are passed, the app will attempt to install the virtual camera system extension. If the --deactivate option is passed, then it will attempt to uninstall it.
After its' built, copy the app file into your Applications folder. This is a console app so when double clicked you will not see output so it is best to run it from bash from the Applications folder like so:
cp -R build/RelWithDebInfo/slobs-virtual-cam-installer.app /Applications
cd /Applications
./slobs-virtual-cam-installer.app/Contents/MacOS/slobs-virtual-cam-installer
echo $?
Notice the addition of the echo $? bash command which will display the application exit code.
The CI build does not code sign the app. When Streamlabs Desktop packages the installer, it replaces the provisioning profile, code signature, and entitlements with Streamlabs' Developer ID. Because of this, the standalone app produced by CI can't activate the camera extension as-is.
To test the standalone app, build it locally with ./build.sh, which signs it automatically (requires an Apple account on the Streamlabs team signed in under Xcode → Settings → Accounts).
