Tips for changing the dimensions of the canvas?

I'm struggling to display a photo captured from the webcam. The sizes are not matching up, and I can't pinpoint where the size is defined in the code. https://i.stack.imgur.com/Is921.png

The camera view is on the left, while the photo should be on the right with an exact match in size, but I'm having trouble locating where to adjust it. I've tried modifying various files without success. Here are the specific files I've attempted to work on.

JavaScript file:

document.addEventListener("DOMContentLoaded", function () {
    // JavaScript code here
})

HTML file:

<!DOCTYPE html>
<html>
    <head>
        <title>Unique Title Here</title>
        <meta charset="UTF-8">
        <link rel="stylesheet" href="style.css">
        <script src="script.js"></script>
    </head>
    <body>
        <div class="container">
            <video id="camera-feed" autoplay></video>
            <img src="#" alt="Photo" id="photo" />
        </div>
    </body>
</html>

CSS file:

.container {
    margin: 0 auto;
}

#camera-feed {
    width: 50%;
    float: left;
}

#photo {
    width: 50%;
    float: right;
}

If anyone knows how to resize the photo to match the camera view, please provide guidance. Thank you!

As stated in the documentation:

Due to privacy concerns, a user's camera and microphone information remains inaccessible. However, an application can specify and request the necessary camera and microphone capabilities through additional constraints. The browser will attempt to adhere to these specifications but may provide alternative resolutions if an exact match is unavailable or overridden by the user.

The article also suggests that specifying a particular size for the video feed can lead to a failed request. Nonetheless, resizing the Canvas after obtaining the video should be a straightforward process based on the video's dimensions.
