can't find variable: MediaRecorder in safari

Question

I am working on video chat application and try to record the video. but I'm facing the problem to record the local Stream or Remote Stream in safari browser. It's Showing an error "can't find variable: MediaRecorder".

This is my code:

function startRecording() {

    recordedBlobs = [];

    var options = { mimeType: 'video/webm;codecs=vp9' };
    if (!MediaRecorder.isTypeSupported(options.mimeType)) {
        console.log(options.mimeType + ' is not Supported');
        options = { mimeType: 'video/webm;codecs=vp8' };
        if (!MediaRecorder.isTypeSupported(options.mimeType)) {
            console.log(options.mimeType + ' is not Supported');
            options = { mimeType: 'video/webm' };
            if (!MediaRecorder.isTypeSupported(options.mimeType)) {
                console.log(options.mimeType + ' is not Supported');
                options = { mimeType: '' };
            }
        }
    }
}
