使用情境
此技能適用於以下情況：
- 用戶明確要求相關功能時
- 任務需要專業領域知識時
- 需要遵循特定工作流程時
快速開始
The simplest way to download a video:
python scripts/download_video.py "https://www.youtube.com/watch?v=VIDEO_ID"
詳細內容請參閱：[example_1.txt](examples/example_1.txt)
### 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
詳細內容請參閱：example_2.txt
Custom Output Directory
Use -o or --output to specify a different output directory:
python scripts/download_video.py "URL" -o /path/to/directory
詳細內容請參閱：[example_3.txt](examples/example_3.txt)
2. Download audio only as MP3:python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -a
1. 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
