Enhance the appearance of the standard black rectangle displaying the messages "No video source" or "No video permissions"

Is there a way to change the styling of the video element that appears as a black rectangle with a strikethrough play button when the user is prompted for permission on Safari? Does it have a specific ID, class, or tag that can be targeted?

I'm currently using Quagga JS for barcode scanning. As far as I know, Quagga creates a video element and requests camera permission. My goal is to hide this element initially using display:none;, but I am unsure how to achieve this. Once permission is granted, the element should display the camera feed; until then, it should be hidden or show a black screen.

Answer №1

I managed to resolve the issue by using JavaScript to hide the element and then displaying it once the Quagga Feedback process is complete. While a CSS-only approach would have been more elegant.

// Initially hide the video preview.
    $('#videoBoundingBox').hide();
    Quagga.init({
        inputStream: {
            name: "Live",
            type: "LiveStream",
            target: document.querySelector('#videoBoundingBox')
        },
        decoder: {
            readers: [
                "code_128_reader",
                "ean_reader"
            ]
        }
    }, function (err) {
        if (err) {
            console.log(err);
            setResult(err);
            err = err.toString();
            if (err.search("NotFoundError")) {
                // Handle case where no camera is found.
                // Perform appropriate action like redirecting or showing alternative content.
            } else if (err.search("NotAllowedError")) {
                // Handle case where user denies camera access permission.
                // Ask for permission again or take suitable action.
            } else {
                // Handle any other errors here.
            }

            return;
        }
        // Show the video preview after initialization.
        $('#videoBoundingBox').show();
        setResult("Initialization completed. Ready to begin");
        console.log("Initialization completed. Ready to begin");
        Quagga.start();
        initializeQuaggaFeedback();
    });
