In certain scenarios, there might be a need for having multiple screens to be shared at the same time, allowing collaboration efforts or simple fun like playing games together with friends or family. To achieve this, Vonage Video API can be utilized to create a Javascript application that allows multiple screen share streams to be shared simultaneously. The application is built using a Basic Video Chat sample from the Opentok Github directory, and users need basic knowledge of JavaScript, a Vonage Video API account, and certain GitHub repositories to develop it. To implement this, session IDs and tokens are generated through the Vonage Video API account, and additional code is added to the HTML and JavaScript files to enable screen sharing. The application allows for separate publisher, subscriber, and screen-share streams to be kept, enabling users to see each other during screen-sharing activities.
