Toggle camera on and off using a single button in Javascript

I'm encountering an issue with my camera functionality. I've implemented a button to open the camera (see code below), but I'm unsure how to turn off the camera when the same button is clicked.

Snippet of my code:

Button: 

<a type="button" onclick="cameraOff()" name="button" id="button"> <i class="fas fa-video fa-2x cam-btn"></i> </a> 

<video id="video" width="640" height="480" autoplay></video>

<script>
    function cameraOff() {

        var video = document.getElementById('video');
        if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
            navigator.mediaDevices.getUserMedia({
                video: true
            }).then(function(stream) {
                video.srcObject = stream;
                video.play();
            });
        }
    }
</script>
