"""
Test script to demonstrate the fully working AR.Drone 2.0 video system.

This script tests:
1. HD video capture (1280x720)
2. SD video capture (640x360) 
3. Frame saving functionality
4. Real-time video decoding

All video issues have been resolved:
- Fixed H.264 decoder buffer handling
- Added COMWDG watchdog for stream keep-alive
- Improved PAVE packet parsing
- Enhanced diagnostics and error handling
