## Security Considerations
> ⚠️ **Important Security Notice**
- **Version Pinning**: This skill uses pinned version `@1.9.0` to prevent execution of different code on each run
- **Code Review**: Inspect the package via `npm view @lzwme/m3u8-dl@1.9.0` or [GitHub](https://github.com/lzwme/m3u8-dl) before execution
- **Sandbox Environment**: Run download tasks in an isolated environment with restricted filesystem permissions
- **ffmpeg Installation**: Ensure ffmpeg is installed from official or trusted sources only
- **Sensitive Variables**: `DS_SECRET` is sensitive - configure carefully to protect WebUI access
- **Legal Compliance**: Ensure downloads comply with local laws and source site terms of service
## Node API
```ts
import { m3u8Download, VideoParser, m3u8BatchDownload } from '@lzwme/m3u8-dl';
// Download m3u8/mp4
await m3u8Download(url, { filename: 'video', saveDir: './downloads' });
// Parse 抖音/皮皮虾/微博
const parser = new VideoParser();
const info = await parser.parse('https://v.douyin.com/xxxxx/');
await parser.download(info, { saveDir: './downloads' });
// Batch download
await m3u8BatchDownload(['name1$url1', 'name2$url2'], { saveDir: './downloads' });
```
## Scenario guide
| Scenario | CLI | Node API |
|----------|-----|----------|
| m3u8/mp4 URL | `m3u8dl <url>` | `m3u8Download(url)` |
| 抖音/皮皮虾/微博 | `--type parser` or `info <url>` | `VideoParser.parse()` |
| Web page with m3u8 | `--type web` | `getM3u8Urls()` |
| Batch download | `"name\|url"` or file | `m3u8BatchDownload()` |
| mp4 conversion | Requires ffmpeg | Set `ffmpegPath` |
