我正在尝试在android浏览器中运行tracking.js,但它不起作用(在我的PC浏览器中,它可以正常运行,例如chrome等),首先我在想它不受android浏览器的支持tracking.js,但是当我打开网址https://trackingjs.com/examples/face_camera.html时,它可以工作,因此受支持,我也复制了该示例,但它不起作用。

<!doctype html>
<html>
    <head>
        <meta charset="utf-8">
        <title>tracking.js - face with camera</title>
        <script src="./build/tracking-min.js"></script>
    </head>
    <body>
        <div class="demo-frame">
            <div class="demo-container">
                <video id="video" width="320" height="240" preload autoplay loop
                    muted></video>
                <canvas id="canvas" width="320" height="240"></canvas>
            </div>
        </div>
        <script>
            window.onload = function() {
                var video = document.getElementById('video');
                var canvas = document.getElementById('canvas');
                var tracker = new tracking.ObjectTracker('face');
                tracker.setInitialScale(4);
                tracker.setStepSize(2);
                tracker.setEdgesDensity(0.1);
                tracking.track('#video', tracker, { camera: true });
            };
        </script>
    </body>
</html>
