LiveKit track processors

Install

<<<<<<< HEAD
yarn add @livekit/track-processors
=======
npm add @livekit/track-processors
>>>>>>> upstream/main

Usage of prebuilt processors

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

=======

Available processors

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

• BackgroundBlur(blurRadius)
• VirtualBackground(imagePath)

Usage example

upstream/main

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

const videoTrack = await createLocalVideoTrack();
<<<<<<< HEAD
await videoTrack.setProcessor(BackgroundBlur(10));
=======
const blur = BackgroundBlur(10);
await videoTrack.setProcessor(blur);
>>>>>>> upstream/main
room.localParticipant.publishTrack(videoTrack);

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

Building your own processors

A track processor consists of one or multiple transformers.

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

## Developing your own processors

A track processor is instantiated with a Transformer.
>>>>>>> upstream/main

```ts
// src/index.ts
export const VirtualBackground = (imagePath: string) => {
<<<<<<< HEAD
  const pipeline = new ProcessorPipeline([new BackgroundTransformer({ imagePath })]);
=======
  const pipeline = new ProcessorWrapper(new BackgroundTransformer({ imagePath }));
>>>>>>> upstream/main
  return pipeline;
};

Available base transformers

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