function bindVolume(v) {
  if (v.dataset.jzVol) { return; }
  v.dataset.jzVol = '1';
  var saved = parseFloat(localStorage.getItem('jz-dpl-volume'));
  if (!isNaN(saved)) { v.volume = saved; }
  v.addEventListener('volumechange', function () {
    if (!v.muted) { localStorage.setItem('jz-dpl-volume', String(v.volume)); }
  });
}
document.querySelectorAll('video').forEach(bindVolume);
var volObs = new MutationObserver(function () {
  document.querySelectorAll('video').forEach(bindVolume);
