The reason is we need to get the presenter privilege first. As a result, the calling of "getDisplayMedia" is from a callback handler. We got the following error from the callback handler: ``` getDisplayMedia error: InvalidAccessError InvalidAccessError: getDisplayMedia must be called from a user gesture handler. ``` At least, the calling should not fail. I think a prompt for surface picker or asking permission is acceptable. Could Safari loosen the restriction just like Chrome browser? I wrote a example: https://www.fanyamin.com/webrtc/examples/desktop_sharing.html You can try it by Safari and Chrome, it is ok by Chrome but failed to start sharing by Safari. 1775923 1 webkit-bug-importer 2021-07-08 22:33:15 -0700 <rdar://problem/80360292>
