触摸设备中的视频JS播放器覆盖按钮

我正在使用VideoJs player 4.2

当我在ios设备的safari浏览器中打开videojs播放器时，默认情况下它可以在本机控件上运行。当我暂停播放器时，我在视频上显示叠加按钮（转到其他页面的链接）。如果我单击按钮，它不会在ios中触发。它在桌面浏览器中运行良好。如果我将本机控件触摸设置为 false，它会显示自定义控件。在这里覆盖按钮和自定义控件有效，但它会很慢，我无法滚动视频，与本机控件相比，它会不流畅。请告诉我任何想法

1. 如果我使用本机控件，则覆盖按钮必须工作
2. 如果我使用自定义控件，那么视频播放器将与本机控件一样流畅

这是我的代码

videojs("ex_video",{"controls":true, "preload":"metadata","width":"auto", "height":"auto",
      "poster":"/images/test.png"},function(){
        var current_player=this; 
        current_player.imageOverlay({
          opacity: 0.5,
          height: '100%',
          width: '50%'
        });
      current_player.on("pause", function(){
        current_player.bigPlayButton.show();
      });
    current_player.on("play", function(){ 
      current_player.bigPlayButton.hide();
    });
});

覆盖按钮代码

(function(vjs) {
  var
   extend = function(obj) {
    var arg, i, k;
    for (i = 1; i < arguments.length; i++) {
     arg = arguments[i];
     for (k in arg) {
      if (arg.hasOwnProperty(k)) {
      obj[k] = arg[k];
      }
    }
  }
return obj;
},
defaults = {
  image_url: '',
  click_url: '',
  start_time: null,
  end_time: null,
  opacity: 0.7,
  height: '15%',
  width: '100%'
},
imageOverlay = function(options) {
var player = this,
    settings = extend({}, defaults, options || {}),
    showingImage = false;
if (settings.start_time === null)
  settings.start_time = 0;
if (settings.end_time === null)
  settings.end_time = player.duration() + 1;
overlay = {
  showImage: function() {
    if (showingImage) {
      return;
    }
    showingImage = true;
    var holderDiv = document.createElement('div');
    holderDiv.id = 'vjs-image-overlay-holder';
    holderDiv.style.height = settings.height;
    holderDiv.style.width = settings.width;
    holderDiv.style.opacity=settings.opacity;
    var overlayLbl1= document.createElement('label');
    overlayLbl1.setAttribute('class','heading-overlay-video');
    overlayLbl1.innerHTML= "Like this class? Why not:";
    var topVideoP=overlay.createEl(overlayLbl1);
    topVideoP.className=topVideoP.className+' top-video-control-overlay';
    holderDiv.appendChild(topVideoP);
    //Save to queue
    var overlayBtn1=document.createElement('button');
    overlayBtn1.value = 'Save to queue';
    overlayBtn1.innerHTML='Save to queue';
    overlayBtn1.setAttribute('class','white medium');
    holderDiv.appendChild(overlay.createEl(overlayBtn1));
    //Add to series button
    var overlayBtn2=document.createElement('button');
    overlayBtn2.value = 'Add to series';
    overlayBtn2.innerHTML='Add to series';
    overlayBtn2.setAttribute('class','white medium');
    holderDiv.appendChild(overlay.createEl(overlayBtn2));
    var overlayLbl2= document.createElement('label');
    overlayLbl2.innerHTML= "music credits";
    overlayLbl2.setAttribute('class','msg-blue');
    var btmVideoP=overlay.createEl(overlayLbl2);
    btmVideoP.className=btmVideoP.className+' bottom-video-control';
    holderDiv.appendChild(btmVideoP);

    player.el().appendChild(holderDiv);
  },
  hideImage: function() {
    if (!showingImage) {
      return;
    }
    showingImage = false;
    player.el().removeChild(document.getElementById('vjs-image-overlay-holder'));
  },
  createEl:function(ele_obj){
    var overlayP=document.createElement('p');
    overlayP.setAttribute('class','overlay-video-content-in');
    overlayP.appendChild(ele_obj);
    return overlayP ;
  }
};
var setTimeoutControl;
player.on('pause', function(){
 setTimeoutControl= setTimeout(function(){overlay.showImage()},5000);
});
player.on('play', function(){ 
  clearTimeout(setTimeoutControl);
  overlay.hideImage();
});    
}; 
vjs.plugin('imageOverlay', imageOverlay); 
}(window.videojs));
