# YouTube Video Downloader

Download YouTube videos with full control over quality and format settings.

## Quick Start

The simplest way to download a video:

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:

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:

python scripts/download_video.py "URL" -f webm

### Audio Only

Use `-a` or `--audio-only` to download only audio as MP3:

python scripts/download_video.py "URL" -a

### Custom Output Directory

Use `-o` or `--output` to specify a different output directory:

python scripts/download_video.py "URL" -o /path/to/directory

## Complete Examples

1. Download video in 1080p as MP4:

python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 1080p

2. Download audio only as MP3:

python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -a

3. Download in 720p as WebM to custom directory:

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
