## 🚀 Usage Examples

### Basic Dashboard
```typescript
import { MidStreamDashboard } from 'midstream-cli';

const dashboard = new MidStreamDashboard();
dashboard.start(100); // 100ms refresh

// Process messages
dashboard.processMessage('Hello world', 5);

// Process streams
const audioData = Buffer.alloc(1024);
dashboard.processStream('audio-1', audioData, 'audio');
```

### Restream Integration
```typescript
import { RestreamClient } from 'midstream-cli';

const client = new RestreamClient({
  webrtcSignaling: 'wss://signaling.example.com',
  enableTranscription: true,
  enableObjectDetection: true
});

client.on('frame', (frame) => {
  console.log(`Frame: ${frame.frameNumber}`);
});

await client.connectWebRTC();
```

### OpenAI + Dashboard
```typescript
import { MidStreamDashboard, OpenAIRealtimeClient } from 'midstream-cli';

const dashboard = new MidStreamDashboard();
dashboard.start();

const openai = new OpenAIRealtimeClient({
  apiKey: process.env.OPENAI_API_KEY
});

openai.on('response.text.delta', (delta) => {
  dashboard.processMessage(delta, delta.length);
});

await openai.connect();
```

## 🔧 Known Limitations

### Current State
1. **WASM Module**: Not compiled (network issues with crates.io)
   - Fallback implementation active
   - Full functionality available without WASM
   - WASM can be compiled later when network is available

2. **Pre-existing Test Failures**: 4 tests failing
   - Related to chaotic behavior detection
   - Not related to new components
   - Due to WASM module unavailability

3. **Video Object Detection**: Framework only
   - Requires TensorFlow.js or similar
   - Mock implementation provided
   - Easy to integrate with actual ML models

4. **Audio Transcription**: Framework only
   - Requires OpenAI Whisper or similar
   - Mock implementation provided
   - Easy to integrate with actual service

### Future Enhancements
1. Real ML model integration for object detection
2. Real transcription service integration
3. WASM module compilation
4. Additional streaming protocols (DASH, MPEG-TS)
5. Web-based dashboard UI
6. Persistence layer for metrics
7. Export capabilities for analysis data

## 📚 Dependencies Added

### None
All new components use existing dependencies:
- chalk (already present)
- dotenv (already present)
- ws (already present)
- http/https (Node.js built-in)
- events (Node.js built-in)

## 🎓 Technical Decisions

### Why Console Dashboard?
- **Minimal**: No additional dependencies

- **Standard**: Node.js native pattern

### Why Mock Implementations for ML?
- **Flexibility**: Choose any ML provider
- **Testing**: Easy to test without ML services
- **Cost**: No forced dependency on paid services
- **Simple**: Clear integration points
