This solution works by creating a direct, peer-to-peer connection between your PC's browser and your phone's browser using WebRTC. Here's the process:

1. PC (Receiver): You'll first open this page on your computer. It will generate a unique connection ID and display it as a QR code below.
2. Mobile (Sender): You'll then use your phone's camera to scan the QR code shown on your PC screen. This will open the same webpage on your phone's browser.
3. Connection: On your phone, press the "Connect" button to establish a secure, real-time video connection with your PC.
4. Recording: Once the stream starts, recording controls will appear below the video. You can start, stop, and download the recording.
