Webrtc zoom ios

To zoom the camera on an iOS device using JavaScript, you can use the getUserMedia API along with the constraints parameter to specify the zoom level. Here's an example:

const constraints = {
  audio: true,
  video: {
    zoom: {
      ideal: 2 // Change the value to adjust zoom level
    }
  }
};

navigator.mediaDevices.getUserMedia(constraints)
  .then(stream => {
    // Use the stream as desired
  })
  .catch(error => {
    console.error(error);
  });

In this example, the constraints object specifies that we want both audio and video, and that we want to set the zoom level to 2. Adjust this value to change the zoom level as desired.

Note that this will only work on iOS devices that support the getUserMedia API. Also, keep in mind that zooming the camera may affect the quality of the video.
