## 🔧 Core Infrastructure Improvements

### Media Server Optimization
- Fixed critical issue with duplicate Node Media Server (NMS) initialization that was causing EADDRINUSE errors on ports 1935 and 8000
- Implemented singleton pattern for NMS instance management to prevent duplicate server instances and undefined session issues
- Centralized NMS instance management through new `src/server/nms-instance.js` module

### API Enhancements
1. New Endpoints:
   - Added `GET /api/streams` endpoint with comprehensive features:
     - Pagination support (`?page=X&limit=Y`)
     - Language filtering (`?language=en`)
     - Category filtering (`?category=gaming`)
     - Stream metadata including viewer counts and quality information
   - Implemented `GET /api/stream/:streamId/status` endpoint providing:
     - Basic stream metadata (title, description, category)
     - Real-time statistics (viewers, uptime)
     - Quality information (resolution, bitrate, codecs)
     - Stream health metrics

### Database Updates
- Added `streamCategory` field to StreamKey model
- Implemented corresponding database migration
- Enhanced stream filtering capabilities based on new category field

### Frontend Improvements
- Fixed ad container visibility issues on initial page load

### Bug Fixes
- Resolved "Cannot convert undefined or null to object" error in streams endpoint
- Fixed "Cannot read property of undefined" error in stream status endpoint
- Corrected require path for streamStatusRouter
- Fixed various migration-related issues

## 🔄 Migration Guide
For developers working with the codebase:
1. Run the latest migrations to add the new `streamCategory` field
2. Update any direct NMS instance references to use the new singleton pattern
3. Review and update stream-related API calls to leverage new filtering capabilities

## 🔜 Next Steps
- Continue monitoring NMS performance after singleton implementation
- Gather feedback on new stream categorization system
- Consider expanding stream metadata capabilities
