Effects Overview

Raven Effects processes a publisher's camera before it's sent anywhere. You think about Raven Effects — never about WebGL, RTP, or which transport carries the video underneath.

Remote Participants / Viewers

Effects run once, on the publisher's machine. A remote participant or a live-stream viewer receives the already-processed video — nothing re-runs per viewer, and viewers never need the Effects SDK themselves.

The shapes

EffectsPipeline        an ordered, mutable list of effects
  ├── filters            brightness, contrast, saturation, exposure,
  │                       temperature, tint, grayscale, sepia, blur
  ├── presets             vivid, warm, cool, cinematic, vintage —
  │                       pure compositions of the filters above
  └── beauty.smooth()      basic whole-frame smoothing (production)

One pipeline attaches to one camera track, on Raven RTC or Raven Live Streaming — the same class either way, since a live stream's camera is an ordinary RTC track underneath.

Quickstart

import { createRTCClient } from '@corvidhq/rtc';
import { effects } from '@corvidhq/effects';
 
const client = createRTCClient({ token, endpoint, iceServers });
const room = await client.join('room-123');
const camera = await room.enableCamera();
 
const pipeline = effects.createPipeline();
pipeline.applyPreset(effects.presets.cinematic);
 
await camera.attachEffects(pipeline);
// camera.detachEffects() reverts to the unmodified track at any time.

See Quickstart for the full walkthrough, including what happens when a browser can't run the pipeline at all.

Supported platforms

"Configuration" and "integration" are listed separately on purpose: you can build and validate a pipeline in JS/Dart on every platform today — what's missing on React Native and Flutter is a native engine to run it against a live camera track. See React Native and Flutter for exactly what that means in practice.
