How It Works

Platform Detection

The tool automatically detects the platform from the URL:

• douyin.com → Douyin
• bilibili.com / b23.tv → Bilibili
• youtube.com / youtu.be → YouTube
• tiktok.com → TikTok
• etc.

Download Methods

1. yt-dlp (default for most platforms)

- Fast and reliable - Supports 1000+ sites - Best for YouTube, Bilibili, etc.

1. DrissionPage (for anti-crawl sites)

- Real browser automation - Bypasses most anti-crawl protections - Used automatically for Douyin - Can be forced with --browser flag

Search Functionality

For Douyin search:

1. Opens browser and navigates to search page
2. Extracts video links from search results
3. Downloads each video using browser session

Troubleshooting

"yt-dlp not installed"

pip install yt-dlp

"DrissionPage not installed"

pip install DrissionPage

Download fails for specific site

Try forcing browser mode:

python video_downloader.py "URL" --browser

Chrome not found (DrissionPage)

DrissionPage will auto-download Chrome on first use. If it fails:

1. Install Chrome manually
2. Or set Chrome path in DrissionPage config

Connection errors

Some sites may block automated access. Try:

• Using a VPN
• Waiting a few minutes between requests
• Using --browser mode

Notes

• Respect Copyright - Only download videos you have permission to use
• Rate Limiting - The tool includes delays to avoid overwhelming servers
• Cookie Support - DrissionPage mode uses browser cookies for authenticated access
• File Naming - Special characters in titles are sanitized for filesystem compatibility

Dependencies

• Python 3.8+
• yt-dlp
• DrissionPage
• requests
• BeautifulSoup4 (optional, for parsing)
