OBS Plugin Template

Introduction

This plugin is meant to make it easy to quickstart development of new OBS plugins. It includes:

The CMake project file
Boilerplate plugin source code
GitHub Actions workflows and repository actions
Build scripts for Windows, macOS, and Linux

Configuring

Open buildspec.json and change the name and version of the plugin accordingly. This is also where the obs-studio version as well as the pre-built dependencies for Windows and macOS are defined. Use a release version (with associated checksums) from a recent obs-deps release.

Next, open CMakeLists.txt and edit the following lines at the beginning:

project(obs-plugintemplate VERSION 1.0.0)

set(PLUGIN_AUTHOR "Your Name Here")

set(LINUX_MAINTAINER_EMAIL "me@contoso.com")

The build scripts (contained in the .github/scripts directory) will update the project line automatically based on values from the buildspec.json file. If the scripts are not used, these changes need to be done manually.

GitHub Actions & CI

The scripts contained in github/scripts can be used to build and package the plugin and take care of setting up obs-studio as well as its own dependencies. A default workflow for GitHub Actions is also provided and will use these scripts.

Retrieving build artifacts

Each build produces installers and packages that you can use for testing and releases. These artifacts can be found on the action result page via the "Actions" tab in your GitHub repository.

Building a Release

Simply create and push a tag and GitHub Actions will run the pipeline in Release Mode. This mode uses the tag as its version number instead of the git ref in normal mode.

Packaging on Linux

The install step results in different directory structures depending on the value of LINUX_PORTABLE - "OFF" will organize outputs to be placed in the system root, such as /usr/, and "ON" will organize outputs for portable installations in the user's home directory. If you are packaging for a Linux distribution, you probably want to set -DLINUX_PORTABLE=OFF.

Signing and Notarizing on macOS

On macOS, Release Mode builds can be signed and sent to Apple for notarization if the necessary codesigning credentials are added as secrets to your repository. You'll need a paid Apple Developer Account for this.

On your Apple Developer dashboard, go to "Certificates, IDs & Profiles" and create two signing certificates:
- One of the "Developer ID Application" type. It will be used to sign the plugin's binaries
- One of the "Developer ID Installer" type. It will be used to sign the plugin's installer
Using the Keychain app on macOS, export these two certificates and keys into a .p12 file protected with a strong password
Encode the .p12 file into its base64 representation by running base64 YOUR_P12_FILE
Add the following secrets in your Github repository settings:
- MACOS_SIGNING_APPLICATION_IDENTITY: Name of the "Developer ID Application" signing certificate generated earlier
- MACOS_SIGNING_INSTALLER_IDENTITY: Name of "Developer ID Installer" signing certificate generated earlier
- MACOS_SIGNING_CERT: Base64-encoded string generated above
- MACOS_SIGNING_CERT_PASSWORD: Password used to generate the .p12 certificate
- MACOS_NOTARIZATION_USERNAME: Your Apple Developer account's username
- MACOS_NOTARIZATION_PASSWORD: Your Apple Developer account's password (use a generated "app password" for this)
