If you have a friend who is on the same network as you, then you can share your Chrome Tab directly by just clicking the Share icon. 

You can also use the QR code reader on your mobile phone to send a link directly to your friend on the same network. You will be able to watch the video from the shared link with only some milliseconds of delay.

The QR code reader has a feature that allows you to copy the link or open the link in your mobile browser.

There is also a QR code reader for desktop computers. This can be used to download the Quick Share Chrome App. The application is used for sharing purposes, and it uses HTTP and webrtc connections to share your streams with other people.
