I'm trying to get the aspect ratio of the webcam using javascript. As per this documentation, it's not working for firefox. https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackSettings/aspectRatio

As Per it says, and I tried it's working in chrome perfectly well and not working in firefox, it gives undefined for aspect ratio in firefox.

But I have seen that this site - https://webcamtests.com/ Somehow able to detect the aspect ratio of the webcam?

Is there any workaround to get the aspect ratio for firefox?
