Google AMP amp-video-iframe用法及代碼示例

簡介：iframe視頻是嵌入在HTML頁麵中的內嵌框架視頻，但是在AMP HTML中，我們使用名為amp-iframe-video的組件將視頻嵌入具有amp-iframe-video的頁麵中，我們可以使用JavaScript嵌入custom-built視頻播放器。

必需的腳本：將amp-video-iframe組件導入標頭。

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

屬性：

src:指定要嵌入的iframe視頻的URL或路徑。
poster:加載視頻時指向圖像URL。這是必填屬性。
implements-media-session:如果iframe應該實現MediaSession API，則應指定此屬性。
implements-rotate-to-fullscreen:當iframe內的文檔實現時，該屬性為True單獨旋轉到全屏。
autoplay:如果設置了該屬性，則視頻將在視頻加載後立即開始播放。

例：
