视频加速16倍代码(图文)

以下是几种实现视频加速播放的方法：

1. 使用浏览器控制台代码

在F12开发者工具的Console面板中执行以下代码：

javascript

// 加速当前页面所有视频元素 document.querySelectorAll('video').forEach(video => { video.playbackRate = 16.0; // 设置播放速度为16倍 }); // 或者针对特定视频元素 document.querySelector('video').playbackRate = 16.0;

2. 更完整的视频加速代码

javascript

// 查找并加速页面中的视频 function accelerateVideos(speed = 16.0) { const videos = document.querySelectorAll('video'); videos.forEach((video, index) => { video.playbackRate = speed; console.log(`Video ${index + 1} accelerated to ${speed}x speed`); }); if (videos.length === 0) { console.log('No video elements found on this page'); } } // 调用函数设置16倍速 accelerateVideos(16.0);

3. 监听新加载的视频

javascript

// 持续监控新添加的视频元素 const observer = new MutationObserver(mutations => { mutations.forEach(mutation => { mutation.addedNodes.forEach(node => { if (node.nodeType === 1 && node.tagName.toLowerCase() === 'video') { node.playbackRate = 16.0; } }); }); }); observer.observe(document.body, { childList: true, subtree: true }); // 同时加速已存在的视频 document.querySelectorAll('video').forEach(video => { video.playbackRate = 16.0; });

4. 创建可控制的加速工具

javascript

// 创建一个更灵活的视频加速工具 class VideoAccelerator { constructor() { this.speed = 1.0; this.videos = []; this.init(); } init() { this.findVideos(); this.setupMutationObserver(); } findVideos() { this.videos = Array.from(document.querySelectorAll('video')); return this.videos; } setSpeed(speed) { this.speed = speed; this.videos.forEach(video => { video.playbackRate = speed; }); console.log(`Set video speed to ${speed}x`); } setupMutationObserver() { const observer = new MutationObserver(mutations => { mutations.forEach(mutation => { mutation.addedNodes.forEach(node => { if (node.nodeType === 1 && node.tagName.toLowerCase() === 'video') { node.playbackRate = this.speed; this.videos.push(node); } }); }); }); observer.observe(document.body, { childList: true, subtree: true }); } reset() { this.setSpeed(1.0); } } // 使用方法 const accelerator = new VideoAccelerator(); accelerator.setSpeed(16.0); // 设置16倍速

5. 一键加速脚本

javascript

// 一键设置16倍速的简化版本 (function() { let videos = document.querySelectorAll('video'); if (videos.length > 0) { videos.forEach(video => { video.playbackRate = 16.0; // 如果视频暂停则开始播放 if (video.paused) { video.play().catch(e => console.log('Auto-play prevented:', e)); } }); console.log(`Accelerated ${videos.length} video(s) to 16x speed`); } else { console.log('No videos found on this page'); } })();
