Video Recording Using Javascript on Web

I am using this to record video on a browser

 navigator.mediaDevices.getUserMedia({ audio: true, video: true }).then(function (camera) {
            callback(camera);
        }).catch(function (error) {
            alert('Unable to capture your camera. Please check console logs.');
            console.error(error);
        });

Can anybody had a workaround how to achieve video recording in safari browser. Is there any workaround, I need help.

I have searched on google found this https://stackoverflow.com/a/58102441

Here, stated we have some open source project which are doing this in safari,

Any help would be appreciated.
