在视口中预加载和自动播放Vimeo视频并淡化封面图像

标签: jquery video vimeo autoplay froogaloop

我正在尝试使用带有froogaloop2的Vimeo API在滚动到视口时在页面上自动播放几个嵌入式iframe视频。我想确保在删除封面图像之前加载视频以避免黑色加载屏幕。我似乎无法使player.addEvent('playprogress', onPlayProgress)回调工作。

视频嵌入的HTML示例在同一页面上使用了4到6次:

<div class="wpb_video_wrapper">
<img class="vimeo-cover" width="100%" height="100%" src="myimageurl">
<iframe class="videoplayer" src="https://player.vimeo.com/video/myvideourl?api=1&amp;autoplay=0&amp;background=1&amp;mute=0&amp;loop=0"></iframe>
</div>

部分工作JS:

<script src='https://f.vimeocdn.com/js/froogaloop2.min.js'></script>

<script type="text/javascript">
