Embed YouTube Block – Fast Loading Videos, Shorts & Playlists vs Lazy Embed

The default embed block for YouTube videos sucks. It slows down your site. The more videos on the page the more it slow. This single-block plugin fixes that. Why this block is better than the default one: Instead of loading the entire iframe, only the video thumbnail is loaded, resulting in significant performance improvements Ability to play multiple different videos as a custom playlist or input a playlist ID to play the whole playlist Ability to use a custom image as the video thumbnail Ability to set a custom aspect ratio value for displaying any kind of YouTube videos Ability to loop continuously once it finishes playing Ability to show related videos from the same channel as the initial video Automatically load the video title as the caption The same UI as the default core/embed, and you can use the video title as the caption of the block with one click It can be transformed from/to the core embed block. Automatically convert all default core embed YouTube blocks to this block with one line of code. This plugin also provides a PHP API for developers to render a YouTube video URL as this block; or to automatically transform core/embed YouTube videos into this block. The simplest example is: better_youtube_embed_block_render_block( ['url' => 'https://youtu.be/paSXmpHU9K4'] ); The example with all the parameters is: better_youtube_embed_block_render_block( [ 'url' => 'https://youtu.be/paSXmpHU9K4', 'aspectRatio' => '16/9', 'isMaxResThumbnail' => false, 'thumbnailFormat' => 'jpg', 'caption' => 'My awesome video', 'caption_kses' => false, 'customThumbnail' => 'https://example.com/bg.jpg', 'settings' => ['loop' => 1, 'rel' => 0], 'echo' => false, ] ); To automatically transform all core/embed YouTube videos on your site to this block, you need to put the following code to the wp-config.php file or your theme/plugin: define('BYEB_SPEED_UP_YOUTUBE_VIDEOS', true); or add_filter( 'byeb_speed_up_youtube_videos', '__return_true' ); On iOS, browsers like Safari and Chrome require two clicks to play videos. If you want to allow users to play videos with a single click, you need to add the following code to the wp-config.php file or your theme/plugin: define('BYEB_FORCE_IFRAME_ON_UNSUPPORTED_BROWSERS', true); Please check out this page to see how fast it helps. The page contains around 30 embedded YouTube videos but they don’t slow down the page.

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
