Hi Guys,

Can we please check to see whether the protocol of wss:// is supported to be used as a whitelist link for use in SEB?

We are using this to whitelist a link such as wss:\/\/.****

Web socket protocol.

Thanks,
Dean

    How do we get the microphone to be adjustable in SEB windows 3.2.0 and SEB macOSX 2.3.2 as a follow up question?
    Do we need to allow a plugin / protocol through SEB somehow?

      Do you mean the microphone input level? We currently don't have controls for that, I guess currently the only was how to adjust it is to do it ahead of starting SEB.

      I don't know what do you mean with allowing a plugin/protocol?

    We are using moodle with a proctoring tool and we are whitelisting. Need to enable microphone / webcam / screensharing ability in a seperate window. Mac 2.3.2 has microphone / webcam options for windows but windows config tool of 3.2.0 does not.

      The browser engines currently are not supporing screen sharing. I don't think Apple supports it for the embeddable browser engine (WKWebView) at all, I will investigate and file a feature request if needed. The Windows CEF engine might support it with some additional code, we have created an issue and will look into it.

      The options in the macOS Preferences are only relevant for the SEB 2.x version for Windows. In SEB 3.2 for Windows, you don't need to enable micophone/webcam. On Mac, you have to wait for the 3.0 release (I expect it to be availiable in around two weeks). Most likely on Mac this will only work on macOS 11.3 or later, I don't think I can backport the functionality which Apple has just added to WKWebView.

    We don't have experience with the wss:// protocol as far as I know. Can you test it yourself and let us know?

    Thanks for replying. Basically a websocket protocol can allow audio communication through the browser such as SIP. We use SIP and our invigilation software runs through this.

    Basically we can whitelist the website but it bottoms out at sharing the microphone setting. Do we know if there's a way we can add the microphone prompts as per this screenshot attached?

    error
    There was a problem sharing your microphone. Please check your device and allow access before trying again.

    Is there a way to customise Video / Microphone through the chrome browser within SEB?
    chrome://settings/content/camera
    chrome://settings/content/microphone

    Thanks,
    Dean

      Access to microphone and camera is automatically granted with the current browser engine.

    microphone gets shared over port 443 yes Im aware the browser engine automatically shares it I guess its our side to investigate.

    On the network tab can we specify ports?

      Yes, you can specify port numbers for the URL filter.

    So we have a UDP range of 16384 - 32768 how would I whitelist that?

      We don't support ranges in the port number argument. Can't you just allow wss:// itself or together with a specific domain? Why do you anyways need to use specific URL filters here, can students create websocket connections in your exam system? I don't think I fully understand your use case.
