# Next Steps - Testing & Deployment Guide

## 🧪 Testing Your Contribution

### 1. Local Testing

#### Backend Setup
```bash
cd backend
npm install
# Make sure FFmpeg is installed: ffmpeg -version
npm start
```

#### Frontend Setup
```bash
cd frontend
npm install
npm run dev
```

### 2. Test Scenarios

#### ✅ Scenario 1: YouTube Streaming
1. Create a YouTube Live stream in YouTube Studio
2. Copy your stream key
3. In FinalCast, create a studio session
4. Click "Go Live" → Select YouTube
5. Paste stream key → Start Streaming
6. Verify stream appears on YouTube
7. Stop streaming and verify it stops on YouTube

#### ✅ Scenario 2: Twitch Streaming
1. Get your Twitch stream key from Dashboard
2. In FinalCast, click "Go Live" → Select Twitch
3. Paste stream key → Start Streaming
4. Verify stream appears on Twitch
5. Stop streaming

#### ✅ Scenario 3: Facebook Streaming
1. Get Facebook stream key from Live Producer
2. In FinalCast, click "Go Live" → Select Facebook
3. Paste stream key → Start Streaming
4. Verify stream appears on Facebook
5. Stop streaming

#### ✅ Scenario 4: Platform Switching
1. Open the streaming modal
2. Switch between YouTube, Twitch, and Facebook tabs
3. Verify the RTMP URL and help text changes
4. Verify icons display correctly

#### ✅ Scenario 5: Error Handling
1. Try streaming without a stream key → Should show error
2. Try streaming with invalid characters → Should be sanitized
3. Try starting a stream while one is active → Should show error
4. Stop a non-existent stream → Should handle gracefully

## 🚀 Deployment Checklist

#### Backend (.env)
```bash
# Required
YOUTUBE_RTMP_URL=rtmp://a.rtmp.youtube.com/live2/
TWITCH_RTMP_URL=rtmp://live.twitch.tv/app/
FACEBOOK_RTMP_URL=rtmp://live-api-s.facebook.com:80/rtmp/
```

#### Frontend (.env)
```bash

The deployment checklist here marks RTMP environment variables with rtmp:// URLs as "Required", which promotes deploying the app with unencrypted RTMP connections to YouTube, Twitch, and Facebook. Using these values in production exposes stream keys and content over plaintext so a network attacker can sniff the streamKey and push arbitrary streams to the victim�s channels. Recommend documenting rtmps:// URLs instead (and noting RTMPS as the default) to ensure deployments use encrypted transport for live streaming.

### System Requirements
- ✅ FFmpeg installed on backend server
- ✅ Node.js 16+ for both frontend and backend
- ✅ Sufficient CPU for video encoding (2+ cores recommended)
- ✅ Stable internet connection (upload speed: 5+ Mbps recommended)

```

## 🐛 Known Issues & Limitations

### Current Limitations
1. **Single Stream Only**: Can only stream to one platform at a time
2. **No Stream Health Monitoring**: No automatic reconnection on failure
3. **Fixed Bitrate**: No adaptive bitrate based on connection
4. **No Analytics**: Stream viewer count not displayed

### Planned Improvements
- Multi-streaming to multiple platforms simultaneously
- Stream health monitoring and auto-reconnect
- Adaptive bitrate streaming
- Viewer count and analytics integration

## 📚 Additional Resources

### Platform Documentation
- [YouTube Live Streaming API](https://developers.google.com/youtube/v3/live)
- [Twitch Stream Setup](https://help.twitch.tv/s/article/broadcasting-guidelines)
- [Facebook Live API](https://developers.facebook.com/docs/live-video-api)

### FFmpeg Resources
- [FFmpeg Documentation](https://ffmpeg.org/documentation.html)
- [FFmpeg RTMP Streaming](https://trac.ffmpeg.org/wiki/StreamingGuide)
- [RTMP Specification](https://www.adobe.com/devnet/rtmp.html)

## 🆘 Troubleshooting

### Stream Won't Start
```bash
# Check FFmpeg installation
ffmpeg -version

# Check backend logs
tail -f backend/logs/app.log

# Test RTMP connection manually
ffmpeg -i test.mp4 -f flv rtmp://live.twitch.tv/app/YOUR_KEY
```

### High CPU Usage
- Reduce video resolution in `videoConfig`
- Lower framerate (from 30 to 24 fps)
- Use faster FFmpeg preset (from 'veryfast' to 'ultrafast')

### Network Issues
- Test upload bandwidth: speedtest.net
- Check firewall rules (allow port 1935 for RTMP)
- Consider using RTMPS for secure connection
