An Expo app demonstrating Decart's Realtime Video models for transforming live camera feeds in real-time.

• Video Restyling (Lucy-restyle) - Transform your camera feed into different artistic styles (anime, cyberpunk, Pixar-style, and 90+ more)
• Video Editing (Lucy) - Make real-time edits to your appearance (change outfits, add accessories, transform into characters)
• Multiple View Modes - Switch between transformed-only, picture-in-picture, vertical split, and horizontal split views
• Front/Back Camera - Switch between cameras on the fly

• Bun (or npm/yarn)
• Expo CLI
• Physical iOS or Android device (camera required - simulators won't work)
• Decart API key from platform.decart.ai

1. Clone the repository:

   git clone https://github.com/DecartAI/decart-example-expo-realtime.git
   cd decart-example-expo-realtime

2. Install dependencies:

   bun install

3. Create your environment file:

   cp .env.example .env.local

4. Add your Decart API key to .env.local:

   EXPO_PUBLIC_DECART_API_KEY=your-api-key-here
   

5. Run on your device:

   # iOS
   bun ios --device
   
   # Android
   bun android --device

The app uses Decart's Realtime SDK to:

1. Capture video from the device camera via WebRTC
2. Stream frames to Decart's inference servers
3. Receive transformed frames back in real-time
4. Display the transformed video alongside or instead of the original

Key integration points:

• useWebRTC.ts - Establishes the WebRTC connection using @decartai/sdk
• lucy-restyle-skin-list.ts / lucy-skin-list.ts - Style definitions with prompts
• Camera.tsx - Orchestrates the camera, styles, and model switching

• Lucy-restyle 2 (lucy-restyle-2) - Video restyling that transforms the entire scene
• Lucy Latest (lucy-latest) - Video editing that modifies specific elements
