LiveKit track processors

Install

npm add @livekit/track-processors

Usage of prebuilt processors

Available processors

This package exposes BackgroundBlur and VirtualBackground as pre-prepared processor pipelines.

• BackgroundBlur(blurRadius)
• VirtualBackground(imagePath)

Usage example

import { BackgroundBlur } from '@livekit/track-processors';

const videoTrack = await createLocalVideoTrack();
const blur = BackgroundBlur(10);
await videoTrack.setProcessor(blur);
room.localParticipant.publishTrack(videoTrack);

async function disableBackgroundBlur() {
  await videoTrack.stopProcessor();
}

async updateBlurRadius(radius) {
  return blur.updateTransformerOptions({blurRadius: blur})
}

Developing your own processors

A track processor is instantiated with a Transformer.

// src/index.ts
export const VirtualBackground = (imagePath: string) => {
  const pipeline = new ProcessorWrapper(new BackgroundTransformer({ imagePath }));
  return pipeline;
};

Available base transformers

• BackgroundTransformer (can blur background or use a virtual background);
