How It Works The skill uses yt-dlp, a robust YouTube downloader that:
Automatically installs itself if not present
Fetches video information before downloading
Selects the best available streams matching your criteria
Merges video and audio streams when needed
Supports a wide range of YouTube video formats
Important Notes
Downloads are saved to /mnt/user-data/outputs/ by default
Video filename is automatically generated from the video title
The script handles installation of yt-dlp automatically
Only single videos are downloaded (playlists are skipped by default)
Higher quality videos may take longer to download and use more disk space
