Camera does not function on macOS

[galzol72]

Describe the bug

The camera does not function in SafeExamBrowser (SEB) on macOS. However, when using Safari without SEB, the camera works normally—after prompting for permission and having it granted, the video appears.

Steps to reproduce the behavior:

Below is the code snippet. (We typically use our own WebRTC proctoring system; this is a simplified, minimal code)
Start Camera

<script> var stream = document.getElementById( "video" ); stream.setAttribute('autoplay', ''); stream.setAttribute('muted', ''); stream.setAttribute('playsinline', ''); function startVideo() { navigator.mediaDevices.getUserMedia({video:true}) .then((stream)=>{ document.getElementById("video").srcObject=stream; }) .catch((err)=>{ alert("Error: " + err.name + ": " + err.message); }); } </script>

Version Information:

• macOS: Sonoma 14.6
• SEB mac version: 3.5

Additional Context:

• The SEB setting browserWindowWebView is set to 3
• The JavaScript API is available, indicating that the modern WebView is in use.
• OS-level permissions for both the camera and microphone are enabled for SEB.
• The site is accessed via HTTPS.
• The Info.plist file includes the following keys and descriptions:
  NSCameraUsageDescription
  This application requires camera access for exam monitoring.
  NSMicrophoneUsageDescription
  This application requires microphone access for exam monitoring.

Troubleshooting Steps and Error:

• The camera permission for SEB was reset using tccutil in the terminal.
• Upon restarting SEB, and clicking on "Start Camera", it prompted for camera access, which was granted.
• However, the following error was encountered:

"Error: NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission."

As you can test with this link Jitsi Meet Test for getDisplayMedia: sebs://safeexambrowser.org/exams/JitsiScreenSharingTest.seb (link also on this page), camera and microphone access for web applications works perfectly with SEB 3.5.

I assume you didn't set the necessary options in Settings / Browser / Media Playback/Capture.

Thank you—it’s now working!

I discovered that I was creating our SEB configuration files using the Windows tool (version 3.9) for both Windows and macOS. I didn’t see the “Media autoplay”, “Allow camera capture”, and “Allow microphone capture” options in that tool (they’re visible in the Mac version). These options generate the following keys:

browserMediaAutoplay
browserMediaAutoplayAudio
browserMediaAutoplayVideo
browserMediaCaptureCamera
browserMediaCaptureMicrophone

Setting these keys allowed the camera to work on macOS.

I might have missed something in the documentation.

Thank you very much for your prompt help!
