# YouTube Video Downloader Download YouTube videos with full control over quality and format settings. ## Quick Start The simplest way to download a video: ```bash python scripts/download_video.py "https://www.youtube.com/watch?v=VIDEO_ID" ``` This downloads the video in best available quality as MP4 to `/mnt/user-data/outputs/`. ## Options ### Quality Settings Use `-q` or `--quality` to specify video quality: - `best` (default): Highest quality available - `1080p`: Full HD - `720p`: HD - `480p`: Standard definition - `360p`: Lower quality - `worst`: Lowest quality available Example: ```bash python scripts/download_video.py "URL" -q 720p ``` ### Format Options Use `-f` or `--format` to specify output format (video downloads only): - `mp4` (default): Most compatible - `webm`: Modern format - `mkv`: Matroska container Example: ```bash python scripts/download_video.py "URL" -f webm ``` ### Audio Only Use `-a` or `--audio-only` to download only audio as MP3: ```bash python scripts/download_video.py "URL" -a ``` ### Custom Output Directory Use `-o` or `--output` to specify a different output directory: ```bash python scripts/download_video.py "URL" -o /path/to/directory ``` ## Complete Examples 1. Download video in 1080p as MP4: ```bash python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 1080p ``` 2. Download audio only as MP3: ```bash python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -a ``` 3. Download in 720p as WebM to custom directory: ```bash python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 720p -f webm -o /custom/path ``` ## 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
