Googleは、Chrome 148でビデオや音声要素の「遅延読み込み」機能をテスト開始すると報告しています。この機能により、特定の要素(画像やiframe)はスクロール位置に近づくと読み込まれるようにすることで、ウェブ閲覧の速度が向上する可能性があります。ChromeおよびChromiumベースのブラウザでは、2019年から画像とiframeの遅延読み込み機能が搭載されていましたが、このアップデートによりビデオや音声要素も遅延読み込みできるようになります(ただし、YouTube埋め込みビデオは既に遅延読み込み可能)。Microsoft EdgeやVivaldiなどの他のChromiumベースのブラウザにも同機能が順次追加される予定です。
"Google has announced that it's currently testing a new feature for Chrome 148 that could speed up day-to-day browsing," reports PC World:
[T]he browser can intelligently postpone the loading of certain elements. Why load all images at the start when it can instead load images as you get close to them while scrolling? Chrome and Chromium-based browsers have had built-in lazy loading support for images and iframes since 2019, but this feature would make browsers capable of lazy loading video and audio elements, too. Note, however, that this won't benefit YouTube video embeds — those are already lazy loadable since they're embedded using iframes. Actual video and audio elements are rarer but not uncommon. In addition to Chrome, lazy loading of video and audio elements is also expected to be added to other Chromium-based browsers, including Microsoft Edge and Vivaldi.
