Introduction

Open Broadcaster Software (OBS) is a popular, free, and open-source software used for live streaming and recording. The OBS Websocket API is a plugin that allows developers to control OBS from different programming languages using web sockets. This API provides a more efficient and flexible way to interact with OBS, making it a must-have for streamers, developers, and broadcasters. In this article, we will explore the OBS Websocket API in detail, from its basics to advanced features and integrations.

What is the OBS Websocket API?

The OBS Websocket API is a plugin that exposes the functionalities of OBS through web sockets. This plugin allows developers to interact with OBS programmatically, using different programming languages such as C++, Python, JavaScript, and more. The OBS Websocket API provides a set of commands and events that can be used to control OBS, such as starting and stopping recordings, changing scenes, adjusting audio and video settings, and more.

How to Install the OBS Websocket API?

Before using the OBS Websocket API, you need to install the plugin. Here are the steps to install the OBS Websocket API:

  1. Go to the OBS Websocket API Github page: https://github.com/Palakis/obs-websocket
  2. Download the latest release of the plugin for your operating system.
  3. Extract the downloaded ZIP file and copy the extracted folder to the OBS plugins directory. The location of the OBS plugins directory depends on your operating system:
    • Windows: C:\Program Files (x86)\obs-studio\obs-plugins\64bit
    • Mac: /Applications/OBS.app/Contents/Resources/obs-plugins/
    • Linux: /usr/share/obs/obs-plugins/
  4. Restart OBS to load the new plugin.

Once installed, you can enable the OBS Websocket API by going to the Tools menu in OBS and selecting the Websocket Server Settings option. In this window, you can configure the server settings, such as the port number, password, and more.

How to Use the OBS Websocket API?

After installing and enabling the OBS Websocket API, you can start using it to control OBS programmatically. Here are the basic steps to use the OBS Websocket API:

  1. Connect to the OBS Websocket API server using a WebSocket client library in your preferred programming language.
  2. Send commands to the server to control OBS, such as starting and stopping recordings, changing scenes, adjusting audio and video settings, and more.
  3. Receive events from the server to get updates on OBS status, such as when a recording starts or stops, when a scene changes, and more.

The OBS Websocket API provides a set of commands and events that you can use to interact with OBS. These commands and events are documented in the OBS Websocket API documentation, which you can find on the OBS Websocket API Github page. The documentation provides detailed information on each command and event, including how to use them and what parameters they accept.

Advanced Features of the OBS Websocket API

The OBS Websocket API provides advanced features that allow you to extend its functionalities and integrate it with other tools and services. Here are some of the advanced features of the OBS Websocket API:

Remote Control

The OBS Websocket API allows you to control OBS remotely, which means you can control OBS from a different machine or device. To do this, you need to configure the OBS Websocket API server to allow remote connections and specify the IP address and port number of the server in your WebSocket client library.

Authentication

The OBS Websocket API provides authentication mechanisms that allow you to secure the communication between your WebSocket client library and the OBS Websocket API server. You can configure the server to require a password or an authentication token to connect and send commands and events.

Plugins

The OBS Websocket API allows you to create plugins that extend its functionalities and add new commands and events. You can use different programming languages and frameworks to develop OBS Websocket API plugins, such as C++, Python, JavaScript, and more. OBS Websocket API plugins are documented in the OBS Websocket API plugins repository, which you can find on the OBS Websocket API Github page.

Integrations

The OBS Websocket API can be integrated with other tools and services to automate and streamline your streaming and recording workflows. For example, you can integrate the OBS Websocket API with chat bots, overlays, graphics, and more. OBS Websocket API integrations are documented in the OBS Websocket API integrations repository, which you can find on the OBS Websocket API Github page.
