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 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

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' });
