How Automatic Video Detection Works
These programs typically detect videos using several technical methods.
1. Network Monitoring
The software watches network traffic and detects video stream URLs.
2. Browser Integration
Extensions scan the webpage for HTML video elements such as:
- <video> tags
- embedded video players
- video source links
3. Cache Extraction
Some tools recover video segments stored in the browser cache while the video is playing.
