Use this skill when the user asks to download, save, or grab YouTube videos. Supports various quality settings (best, 1080p, 720p, 480p, 360p), multiple formats (mp4, webm, mkv), and audio-only downloads as MP3.\n---\n\n# YouTube Video Downloader\n\nDownload YouTube videos with full control over quality and format settings.\n\n## Quick Start\n\nThe simplest way to download a video:\n\n```bash\npython scripts/download_video.py \"https://www.youtube.com/watch?v=VIDEO_ID\"\n```\n\nThis downloads the video in best available quality as MP4 to `/mnt/user-data/outputs/`.\n\n## Options\n\n### Quality Settings\n\nUse `-q` or `--quality` to specify video quality:\n\n- `best` (default): Highest quality available\n- `1080p`: Full HD\n- `720p`: HD\n- `480p`: Standard definition\n- `360p`: Lower quality\n- `worst`: Lowest quality available\n\nExample:\n```bash\npython scripts/download_video.py \"URL\" -q 720p\n```\n\n### Format Options\n\nUse `-f` or `--format` to specify output format (video downloads only):\n\n- `mp4` (default): Most compatible\n- `webm`: Modern format\n- `mkv`: Matroska container\n\nExample:\n```bash\npython scripts/download_video.py \"URL\" -f webm\n```\n\n### Audio Only\n\nUse `-a` or `--audio-only` to download only audio as MP3:\n\n```bash\npython scripts/download_video.py \"URL\" -a\n```\n\n### Custom Output Directory\n\nUse `-o` or `--output` to specify a different output directory:\n\n```bash\npython scripts/download_video.py \"URL\" -o /path/to/directory\n```\n\n## Complete Examples\n\n1. Download video in 1080p as MP4:\n```bash\npython scripts/download_video.py \"https://www.youtube.com/watch?v=dQw4w9WgXcQ\" -q 1080p\n```\n\n2. Download audio only as MP3:\n```bash\npython scripts/download_video.py \"https://www.youtube.com/watch?v=dQw4w9WgXcQ\" -a\n```\n\n3. Download in 720p as WebM to custom directory:\n```bash\npython scripts/download_video.py \"https://www.youtube.com/watch?v=dQw4w9WgXcQ\" -q 720p -f webm -o /custom/path\n```\n\n## How It Works\n\nThe skill uses `yt-dlp`, a robust YouTube downloader that:\n- Automatically installs itself if not present\n- Fetches video information before downloading\n- Selects the best available streams matching your criteria\n- Merges video and audio streams when needed\n- Supports a wide range of YouTube video formats\n\n## Important Notes\n\n- Downloads are saved to `/mnt/user-data/outputs/` by default\n- Video filename is automatically generated from the video title\n- The script handles installation of yt-dlp automatically\n- Only single videos are downloaded (playlists are skipped by default)\n- Higher quality videos may take longer to download and use more disk space\n\n## Reusability\n\nThis skill is designed to be reusable by other skills:\n\n**Used by**:\n- `youtube-to-xiaoyuzhou` - Uses the audio-only download feature to get YouTube audio for podcast publishing","tagline":"Download YouTube videos with customizable quality and format options.
