Screen-share Parameters

Labels, audio filters, type, bitrate, quality etc.

Screen-share parameters are separated by where they are applied:

• Source side options belong on publisher links, such as &push, guest invite links, or room participants who will share a screen.

• Viewer side options belong on receive links, such as &view or &scene, and control how incoming screen shares are requested or displayed.

Use &screensharehide when the screen-sharing publisher should not see their own local screen-share preview. Use &noscreenshare when a viewer or scene link should not load incoming screen shares.
