Google AMP amp-video-iframe用法及代码示例

简介：iframe视频是嵌入在HTML页面中的内嵌框架视频，但是在AMP HTML中，我们使用名为amp-iframe-video的组件将视频嵌入具有amp-iframe-video的页面中，我们可以使用JavaScript嵌入custom-built视频播放器。

必需的脚本：将amp-video-iframe组件导入标头。

<script async custom-element="amp-video-iframe" src= 
"https://cdn.ampproject.org/v0/amp-video-iframe-0.1.js"> 
</script>

属性：

src:指定要嵌入的iframe视频的URL或路径。
poster:加载视频时指向图像URL。这是必填属性。
implements-media-session:如果iframe应该实现MediaSession API，则应指定此属性。
implements-rotate-to-fullscreen:当iframe内的文档实现时，该属性为True单独旋转到全屏。
autoplay:如果设置了该属性，则视频将在视频加载后立即开始播放。

例：
