A much easier way than all of these answers is just replacing the whole src. This works for all modals and you can adjust iframe class as required.
$('.modal').on('hidden.bs.modal', function(e) {

var rawVideoURL = $("iframe")[0].src;
closestIframe[0].src = "";
closestIframe[0].src = rawVideoURL;
});
