Title: Lazy Embed Author: beleaf Published: 2023 年 2 月 2 日 Last modified: 2024 年 5 月 22 日 --- 搜索插件 ![](https://ps.w.org/lazy-embed/assets/banner-772x250.png?rev=2865625) **该插件尚未通过WordPress的最新3个主要版本进行测试**。 当与较新版本的WordPress一起 使用时，可能不再受到维护或支持，并且可能会存在兼容性问题。 ![](https://ps.w.org/lazy-embed/assets/icon-256x256.png?rev=2865625) # Lazy Embed 作者：[beleaf](https://profiles.wordpress.org/beleaf/) [下载](https://downloads.wordpress.org/plugin/lazy-embed.1.6.3.zip) * [详情](https://cn.wordpress.org/plugins/lazy-embed/#description) * [评价](https://cn.wordpress.org/plugins/lazy-embed/#reviews) * [开发进展](https://cn.wordpress.org/plugins/lazy-embed/#developers) [支持](https://wordpress.org/support/plugin/lazy-embed/) ## 描述 Videos are one of the largest assets that can be loaded on a webpage, and as such are one of the largest contributors to slow performance and high carbon emissions. In fact, adding a Youtube embed to a page using the latest default WordPress theme, increased the page transfer size from 21 kb to 973 kb, and loaded an additional 27 resources. That’s an increase in transfer size of 4533%. Adding a Vimeo video increased the transfer from 21 kb to 276 kb, an increase in transfer size of 1214%, and loaded an additional 7 resources. The Lazy Embed plugin defers the loading of any resource required for playing the video until the video is requested to be played. It does this by adding a srcdoc attribute to the iframe which shows in place of the normal iframe content. Currently the following third parties are supported * Youtube * Vimeo * Dailymotion ## 常见问题 ### Are there any settings Nope, install the plugin and you are good to go. There are some filters available for modifying the behaviour though. ### Can I stop the plugin from modifying an iframe Yes you can, add the “lazy-embed-ignore” class to the iframe itself or using the gutenberg editor ### Why do I have to click a video twice somtimes for it to play? Browsers have become more restrictive around autoplaying a video. The first click on a video never reaches the video host, so they then show the default thumbnail. After the first time a Lazy Embed is interacted with, subsequent videos from that provider will not require a second load. ### I have updated the thumbnail for my video in Youtube/Vimeo/Dailymotion. Why am I not seeing the updated thumbnail? The thumbnails are cached to improve the performance (uncached frontend pages) and reduce the emissions (less requests to the video platform) of the Lazy Embed plugin. The cache is known as transients. You can clear the transient cache using a plugin like [WP-Sweep](https://wordpress.org/plugins/wp-sweep/) ### Why does it not work for my videos? It could be for one of a few reasons. 1. A thumbnail for the embed could not be retrieved. If this is the case, send us a message with the video and we will take a look ## 评价 ![](https://secure.gravatar.com/avatar/7cbb536267cc0ae4eeea1eff6579d022825b1e02b716d07b468e6aa40952c1ae? s=60&d=retro&r=g) ### 󠀁[The best plugin.](https://wordpress.org/support/topic/video-thumbnail-does-not-load/)󠁿 [dyneezinha](https://profiles.wordpress.org/dyneezinha/) 2024 年 5 月 22 日 1 回复 It works perfectly. The best plugin I found. I recommend! Sorry for any errors in writing, I’m originally from Brazil and I only write in Portuguese. I’m using google translator. ![](https://secure.gravatar.com/avatar/cb9358ffd8587c3498800d9c404ab24e3f8cf81596d7038125e10a65c76226de? s=60&d=retro&r=g) ### 󠀁[Just works! Much leaner YouTube and Vimeo embeds.](https://wordpress.org/support/topic/just-works-much-leaner-youtube-and-vimeo-embeds/)󠁿 [Bjarne Oldrup](https://profiles.wordpress.org/oldrup/) 2024 年 2 月 29 日 1 回复 Lazy Embed is a no fuss, super simple and robust way to improve on performance, privacy and sustainability of video embeds using the block editor. Some highlights include: Works with existing and new video embeds. Accessibility-friendly; video can be triggered with keyboard. No settings or custom code needed; activate and be done. Leave no trace behind; deactivate if you don’t like it. Valid HTML output; quality code. Much improved Google Lighthouse scores. If you mostly embed YouTube, Vimeo or Daily Motion videos, and you don’t need custom overlays with, say, link to privacy polices (hint: you can link to these in the captions), Lazy Embed is definitely worth a try. Tested with WordPress 6.5 beta 3 and PHP 8.3; no issues encountered. There are similar plugins out there, which allow for more customizations and support for more embed types. These might give you more flexibility, but it’s also more work. Lazy Embed definitely has my recommendation.
