Connecting to Meld Studio

Control Meld Studio scenes, layers, audio, and streaming from Helmo Live through Qt WebChannel.

TutorialIntermediateUpdated

Connect Meld Studio to Helmo Live for scene management, layer control, audio mixing, and streaming operations.

What is Meld Studio?

Meld Studio is a local broadcast production app that runs on your own machine (an alternative to OBS). It is not a cloud service. Helmo controls it through the Qt WebChannel protocol over a WebSocket (default port 13376), either Local (same machine or local network) or through Helmo Middleware.

Prerequisites

  • Meld Studio running on your machine (default WebSocket port: 13376).
  • Either a direct local connection or Helmo Middleware installed on the same machine.

Connecting in Helmo

  1. Go to Connect and click + Add Integration.
  2. Select Meld Studio as the type.
  3. Enter a name (for example, "Meld Studio Main").
  4. Choose your connection mode: - Direct: if Meld Studio runs on the same machine or local network. Enter the WebSocket URL (default: ws://127.0.0.1:13376). - Middleware: if Meld Studio is on a remote machine. Select your Helmo Middleware instance.
  5. Click Save.
