PHP轮播只显示视频顶部？

Question

我在我的php网站上有这个旋转木马，里面有一个视频（和两张图片），但它只显示了视频的顶部？我可以把它作为视频的中心而不是顶部吗？

<header id="myCarousel" class="carousel slide" data-pause="hover">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#myCarousel" data-slide-to="1"></li>
    <li data-target="#myCarousel" data-slide-to="2"></li>

</ol>

<!-- Wrapper for slides -->
<div class="carousel-inner">
    <div class="item active">
        <div class="fill embed-responsive embed-responsive-16by9">
            <video autoplay class="embed-responsive-item">

    </div>
    <div class="item">

    </div>
    <div class="item">

    </div>
</div>
