Stream into a Pipeline with OBS

How to stream with a Livepeer Pipeline using OBS

Before you begin, you’ll need:

• OBS Studio installed on your computer

• A Livepeer API key

• A pipeline ID (find one in the Pipelines application)

Step 1: Create a stream

First, create a stream that uses your chosen pipeline. Using your preferred language:

const livepeer = new LivepeerClient({
  apiKey: 'your-api-key'
});

const stream = await livepeer.Stream.create({
  name: 'My AI Stream',
  pipeline: {
    id: 'anime-style-transfer',
    params: {
      styleIntensity: 0.8
    }
  }
});

// Save these values
console.log({
  streamKey: stream.streamKey,
  rtmpIngestUrl: stream.rtmpIngestUrl,
  playbackUrl: stream.playbackUrl
});

Step 2: Configure OBS

1. Open OBS Studio

2. Click the ”+” under Sources and add your video source:

   • For webcam: Select “Video Capture Device”

   • For screen capture: Select “Display Capture”

Step 3: Set up streaming settings

1. Click “Settings” → “Stream”

2. For “Service” select “Custom…”

3. Set “Server” to your rtmpIngestUrl

4. Set “Stream Key” to your streamKey

5. Click “Apply”

Step 4: Start streaming

1. Click “Start Streaming” in OBS

2. Your stream should begin within 30-45 seconds

3. View your stream at the playbackUrl. You can also use the hosted Livepeer player to view the stream, at https://lvpr.tv/?v=<playbackID>

Common issues

• Black screen: Check that your video source is properly selected and visible in OBS

• Connection failed: Verify your stream key and RTMP URL are correct

• High CPU usage: Lower your video output resolution in OBS Settings → Video

Next steps

• Update pipeline parameters in real-time

• Distribute your stream with Livepeer Studio
