OBS OSC Plugin: Control OBS Studio with OSC

So, you're looking to dive into the world of controlling OBS Studio with OSC (Open Sound Control), huh? Well, you've come to the right place! This article will break down everything you need to know about the OBS OSC plugin, from what it is and why you might want to use it, to how to get it set up and start tweaking your OBS settings with the power of OSC. Let's get started, folks!

What is OSC and Why Use It with OBS Studio?

First things first, let's clarify what OSC actually is. OSC, or Open Sound Control, is a protocol for communication among computers, sound synthesizers, and other multimedia devices. Think of it as a more flexible and advanced alternative to MIDI. While MIDI is great for musical instruments, OSC shines when you need to control a wider range of parameters and devices with higher precision and speed. OSC transmits data over a network (usually Ethernet or Wi-Fi) allowing for remote control and automation.

So, why would you want to use OSC with OBS Studio? Well, there are a ton of cool reasons:

  • Remote Control: Imagine controlling your OBS scenes, sources, and transitions from a separate device, like a tablet or smartphone. No more alt-tabbing or fumbling with OBS while you're live! Using OSC, you can create custom interfaces that provide precise control from anywhere on your network. This is incredibly useful for streamers who want to manage their broadcast without being tied to their main computer.
  • Automation: OSC allows you to automate complex tasks in OBS. You could, for example, trigger scene changes based on audio levels or even integrate OBS with other software or hardware. Imagine having your lights change automatically when you switch to a different scene, or starting a recording when a specific event occurs in your game. The possibilities are endless!
  • Custom Interfaces: The OBS OSC plugin lets you design your own custom control surfaces using software like TouchOSC, Lemur, or even custom-built applications. This means you can create an interface tailored to your specific needs and workflow. No more generic controls – you get exactly what you want!
  • Integration with Other Software/Hardware: OSC is widely supported in the world of music, art, and interactive installations. Using the OBS OSC plugin, you can seamlessly integrate OBS with other software and hardware that support OSC. This opens up a world of creative possibilities for live performances, interactive streams, and unique broadcasting setups.

In essence, using the OBS OSC plugin supercharges your OBS Studio setup, giving you unparalleled control and flexibility. Whether you're a streamer, content creator, or live performer, OSC can help you take your productions to the next level.

Installing the OBS OSC Plugin

Okay, now that you're convinced that the OBS OSC plugin is the bee's knees, let's get it installed! The installation process is relatively straightforward, but it's crucial to follow the steps carefully to avoid any issues. Here's a step-by-step guide:

  1. Download the Plugin: Head over to the official OBS OSC plugin page on the OBS Project website or GitHub. Look for the latest release that's compatible with your operating system (Windows, macOS, or Linux). Make sure you download the correct version for your OBS Studio installation.

  2. Extract the Files: Once you've downloaded the plugin, extract the contents of the ZIP file to a temporary location. You should see a few files and folders, including a data folder and a .dll (Windows) or .so (macOS/Linux) file.

  3. Copy the Files to the OBS Studio Directory: This is the crucial step. You need to copy the extracted files into the correct OBS Studio directory. The location of this directory varies depending on your operating system:

    • Windows: C:\Program Files\obs-studio\
    • macOS: /Applications/OBS.app/Contents/ (Right-click on OBS.app and select "Show Package Contents")
    • Linux: /usr/lib/obs-plugins/ or /usr/local/lib/obs-plugins/ (depending on your installation)

    Make sure to copy the data folder and the .dll or .so file into the appropriate subdirectories within the OBS Studio directory. For example, the .dll file on Windows should go into C:\Program Files\obs-studio\obs-plugins\. The data folder should go into C:\Program Files\obs-studio\data\obs-plugins\.

  4. Restart OBS Studio: After copying the files, restart OBS Studio to load the plugin. If everything went smoothly, you should see the OBS OSC plugin listed in the "Tools" menu.

  5. Verify Installation: Go to Tools > obs-websocket settings. If you see a tab labeled "OSC," the plugin has been installed correctly! If you don't see the OSC tab, double-check that you've copied the files to the correct directories and restarted OBS Studio.

That's it! The OBS OSC plugin should now be installed and ready to go. If you encounter any issues during the installation process, consult the plugin's documentation or online forums for troubleshooting tips.

Configuring the OBS OSC Plugin

Alright, with the plugin successfully installed, let's dive into configuring it. This part is crucial to getting OSC commands flowing between your control device and OBS Studio. The configuration is done through the OBS Studio settings:

  1. Open OBS Settings: In OBS Studio, go to Tools > obs-websocket settings. This will open the OBS-Websocket settings window.
  2. Navigate to the OSC Tab: You should see a tab labeled "OSC." Click on it to access the OSC plugin settings.
  3. Configure OSC Settings: Here, you'll find several options to configure the plugin:
    • Enable OSC: Make sure this box is checked to enable the OSC plugin. If it's not checked, OSC commands won't be processed.
    • Port: This is the port number that the OBS OSC plugin will listen on for incoming OSC messages. The default port is usually 8000, but you can change it if needed. Make sure that the port you choose is not being used by any other application on your system.
    • IP Address: This is the IP address that the OBS OSC plugin will bind to. By default, it's set to 0.0.0.0, which means it will listen on all network interfaces. If you want to restrict access to the plugin to a specific IP address, you can change this setting. However, in most cases, leaving it at 0.0.0.0 is fine.
    • Parameter Prefix: This is a prefix that will be added to all OSC addresses. This can be useful for organizing your OSC commands and preventing conflicts with other OSC applications. The default prefix is /obs/, but you can change it to anything you like. For example, if you set the prefix to /myobs/, then all OSC addresses will start with /myobs/.
    • Verbose Logging: Enable this option to log detailed information about OSC messages to the OBS Studio log file. This can be helpful for troubleshooting issues with OSC communication.
  4. Apply and Restart (If Necessary): After making any changes to the OSC settings, click the "Apply" button to save them. In some cases, you may need to restart OBS Studio for the changes to take effect. If you're not sure, it's always a good idea to restart OBS Studio after changing any settings.

With the OBS OSC plugin configured, it's time to set up your OSC control device or software to send commands to OBS Studio.

Sending OSC Commands to OBS Studio

Now for the fun part: sending OSC commands to OBS Studio! This is where you'll use your chosen OSC control software (like TouchOSC or Lemur) to manipulate OBS settings. Here's a general overview of how it works:

  1. Choose Your OSC Control Software: There are many OSC control software options available, both free and paid. Some popular choices include TouchOSC, Lemur, and Open Stage Control. Choose one that suits your needs and preferences.

  2. Create a Layout: In your OSC control software, create a layout with the controls you want to use to manipulate OBS Studio. This could include buttons, sliders, knobs, and other interface elements. Each control will need to be assigned an OSC address and value range.

  3. Map OSC Addresses to OBS Actions: This is where you tell your OSC control software which OBS actions to trigger when you interact with the controls in your layout. The OBS OSC plugin exposes a wide range of actions that you can control, including:

    • Scene Switching: Switch to a specific scene in your scene collection.
    • Source Visibility: Show or hide a specific source in your current scene.
    • Source Volume: Adjust the volume of a specific audio source.
    • Start/Stop Streaming: Start or stop your live stream.
    • Start/Stop Recording: Start or stop recording your broadcast.
    • Transition Control: Trigger a specific transition between scenes.

    To map an OSC address to an OBS action, you'll need to know the correct OSC address for that action. The OBS OSC plugin documentation provides a comprehensive list of available OSC addresses and their corresponding actions. You can also use the verbose logging feature in the plugin to see the OSC addresses that are being sent when you perform actions in OBS Studio.

  4. Configure OSC Settings in Your Control Software: In your OSC control software, you'll need to configure the OSC settings to match the settings you configured in the OBS OSC plugin. This includes the IP address and port number of the OBS Studio instance you want to control. Make sure that your OSC control software is sending OSC messages to the correct IP address and port.

  5. Test Your Setup: Once you've configured everything, it's time to test your setup. Start OBS Studio and your OSC control software. Then, interact with the controls in your layout and see if the corresponding actions are triggered in OBS Studio. If everything is working correctly, you should be able to control OBS Studio from your OSC control software!

Troubleshooting tip: if things aren't working as expected, double-check that your OSC settings in both OBS Studio and your control software are correct. Also, make sure that there are no firewalls or other network restrictions that are blocking OSC communication.

Examples of OSC Control

To give you some inspiration, here are a few examples of how you can use the OBS OSC plugin to control OBS Studio:
