WebRTC-based peer-to-peer screen sharing, with support for one-to-many screen sharing. Share the [Viewer URL] with others, then click the [Start Sharing] button to begin screen sharing. This feature is built entirely on standard browser capabilities. If it does not work, please upgrade to the latest version of browsers such as Google Chrome or Microsoft Edge. No additional software installation is required. The shared screen content is transmitted directly between peers and does not pass through a server, providing enhanced security and privacy protection. WebRTC is well supported in desktop browsers and should work normally on most personal computers. On mobile devices, if you encounter an error related to "getDisplayMedia", it indicates that the browser does not support screen sharing. Since this is a one-to-many peer-to-peer transmission, the smoothness and quality of the shared screen depend on the sharer's available upload bandwidth when multiple viewers are connected.
