使用transform代替保证金。检查下面更新的代码段...

.videoDiv {
  position: fixed; 
  left: 50%; 
  top: 50%; 
  transform: translate(-50%, -50%);
}
<div data-role="header">
</div>

<div data-role="main" class="ui-content" >
  <span class="videoDiv" style="">
    <video width="block" height="auto"   id="video_mute" controls>
      <source src="angka/bilangan_1.mp4" type="video/mp4">
    </video>
  </span>
</div>
