Ruby Clients for OBS Studio WebSocket v5.0

Requirements

  • OBS Studio
  • OBS Websocket v5 Plugin
    • With the release of OBS Studio version 28, Websocket plugin is included by default. But it should be manually installed for earlier versions of OBS.
  • Ruby 3.0 or greater

Installation

Bundler

bundle add obsws
bundle install

Use

Example main.rb

Pass host, port and password as keyword arguments.

require "obsws"

class Main
  def run
    OBSWS::Requests::Client
      .new(host: "localhost", port: 4455, password: "strongpassword")
      .run do |client|
        # Toggle the mute state of your Mic input
        client.toggle_input_mute("Mic/Aux")
      end
  end
end

Main.new.run if $PROGRAM_NAME == __FILE__

Passing OBSWS::Requests::Client.run a block closes the socket once the block returns.

Requests

Method names for requests match the API calls but snake cased.

example:

# GetVersion
resp = r_client.get_version

# SetCurrentProgramScene
r_client.set_current_program_scene("BRB")

For a full list of requests refer to Requests

Events

Register on_ callback methods. Method names should match the api event but snake cased.

example:

class Observer
    def initialize
        @e_client = OBSWS::Events::Client.new(host: "localhost", port: 4455, password: "strongpassword")
        # register callback methods with the Event client
        @e_client.register(
          [
            method(:on_current_program_scene_changed),
            method(:on_input_mute_state_changed)
          ]
        )
    end

    # define "on_" event methods.
    def on_current_program_scene_changed(data)
        ...
    end
    def on_input_mute_state_changed(data)
        ...
    end
    ...
end

For a full list of events refer to Events

Attributes

For both request responses and event data you may inspect the available attributes using attrs.

example:

resp = cl.get_version
p resp.attrs

def on_scene_created(data):
    p data.attrs

Errors

If a request fails an OBSWSError will be raised with a status code.

For a full list of status codes refer to Codes

Logging

To enable logs set an environmental variable OBSWS_LOG_LEVEL to the appropriate level.

example in powershell:

$env:OBSWS_LOG_LEVEL="DEBUG"

Tests

To run all tests:

bundle exec rake -v
