Safari permissions and media sharing issues without SharedArrayBuffer enabled

[Betil (Yuantao)]

Issue Description

We’re encountering several critical issues in Safari when SharedArrayBuffer is disabled in our environment. Note that all media sharing works perfectly between other browsers (Chrome, Firefox, Edge):

1. Screen Sharing: Safari → Chrome
   Issue: No system permission dialog appears in Safari when attempting to share screen
   Result: Screen sharing fails to initiate, no further response or functionality
   Expected: System should prompt user to select which screen to share
2. Screen Sharing: Chrome → Safari
   Issue: Screen sharing fails with error: OPERATION_TIMEOUT
   Unable to complete screen sharing process
3. Camera: Chrome → Safari
   Issue: Safari only receives gray video feed
   No valid video content is displayed
4. Camera: Safari → Chrome
   Issue: No camera permission prompt appears in Safari
   Result: Camera remains non-functional, no further response
   Expected: Should prompt for camera permissions and enable video feed

Environment Details

Safari Version: 18.2
VideoSDK Version: 2.1.0 (Latest)
Session ID: TIKQAp7YQWmJX4B3etz4Kg==

Important Notes

SharedArrayBuffer cannot be enabled due to site restrictions
Issues #1 and #4 appear to share the same root cause: Zoom fails to properly request permissions in Safari
While enabling SharedArrayBuffer would resolve most issues, this is not an option for our implementation

Any assistance from the technical team would be greatly appreciated.
