是否可以在视频加载之前加载背景图像？

Question

我在我的网站上使用YouTube视频背景，似乎花费的时间超过了我想加载的时间。为了绕过这个，我想添加一个背景图像，以显示在视频背后，直到它加载。

有一种简单的方法吗？

由于

HTML：

<section class="small-background-section">
    <a id="bgndVideo" class="player" data-property="{videoURL:'https://www.youtube.com/watch?v=iNJdPyoqt8U',containment:'body',autoPlay:true, mute:true, startAt:0, opacity:1}"></a>

    <div class="pattern"></div> 
    <div class="small-background-container">
        <center>
            <img src="images/NewLogo.png" style='width:50%;max-width: 300px;padding:0px;'>
        </center>
    </div>                                                    
</section>
