A Chrome / Edge / Atlas extension for video auto-playing(note: if your video material is not helpful/waste-of-time to you, this is a good approach for U to try).
Video Helper helps find "play" buttons of videos on webpages, automatically clicks "next" button.
It is designed for owned or authorized testing environments only.
Current version: 2.3.3
This project is intended for defensive testing and authorized web video workflow analysis.
You can use it to:
- test your own web video platform;
- check whether video controls are too easy to automate;
- debug course or resource navigation logic;
- verify whether non-video resources are handled correctly;
- improve server-side anti-abuse and progress-validation design.
Do not use this extension to bypass learning requirements, falsify attendance, fake video progress, or violate any platform rules.
Video Helper works on Chromium-based browsers, including:
- Google Chrome
- Microsoft Edge
- Atlas Browser
- Other Chromium-based browsers that support unpacked extensions
After the extension is installed for the first time, Video Helper automatically opens a configuration page.
You can configure:
- allowed test URL / host;
- wait limit;
- scan interval.
The page control panel only appears on the configured whitelist host.
Clicking the extension icon opens a simple menu:
- Open Configuration
- Open Status Panel
- Coming Soon
The popup is only used as an entry point. Runtime controls are shown inside the page control panel.
On a whitelisted website, Video Helper can open a floating control panel.
The panel includes:
- Scan Page
- Play Current Video
- Next
- Highlight Next
- Start
- Stop
- Clear Highlights
The panel can be minimized. When minimized, a small Video Helper chip remains in the corner so you can restore it.
Video Helper scans the current page for:
- visible
<video>elements; - possible video play buttons;
- possible next-resource buttons.
It avoids detecting its own UI elements and ignores common non-video buttons such as:
开始答题答题测验考试作业练习quizexamtesthomeworkexercisequestion
This reduces false detections when the page contains quizzes, exercises, homework, or exam buttons.
| Setting | Meaning | Default |
|---|---|---|
Wait Limit |
Maximum time to wait for a video after opening a resource | 180 seconds |
Scan Interval |
How often the page is scanned while waiting | 15 seconds |
Example:
Wait Limit = 60
Scan Interval = 5
This means Video Helper waits up to 60 seconds and scans every 5 seconds.
When the page has a native next button, Video Helper tries to use it first.
If no native next button exists, it tries to resolve the next resource by:
- reading the current activity ID from the URL hash;
- scanning course or resource links in the page DOM;
- finding the current resource in the activity list;
- opening the next resource in order.
This is useful for testing platforms where some resources do not provide an explicit Next button.

If Video Helper can easily automate your video workflow, consider improving your platform design.
Recommended server-side checks:
- do not trust frontend-only progress values;
- do not allow direct
completed=trueupdates; - use server-side watch sessions;
- validate heartbeat timing;
- validate video progress continuity;
- reject large progress jumps;
- prevent replayed progress requests;
- rate-limit suspicious activity;
- calculate completion on the server side;
- do not rely only on mouse, focus, or visibility checks.
Frontend checks are useful, but they should not be the only source of truth.
- Fixed false detection of quiz, exam, and homework buttons as play controls.
开始答题is no longer detected as a play button.- Play detection now avoids generic
startlabels unless they are clearly related to video playback.
- Fixed self-detection issue.
- The scanner no longer detects Video Helper's own panel, buttons, labels, or progress UI.
- Project name changed to Video Helper.
- Added first-run configuration page.
- Added popup menu.
- Added whitelist-only page panel.
- Added minimizable page control panel.
- Moved
In Progressfrom the center overlay into the page control panel. - Simplified popup into a configuration window.
- Replaced Liquid Glass style with a readable high-contrast UI.
- Improved next-button filtering.
- Added configurable timing.
- Added manual
Nextbutton. - Added path-based next-resource resolver.

Video Helper 是一个适用于 Chrome / Edge / Atlas 浏览器的网页视频流程测试扩展。
它可以帮助开发者和测试人员检查:一个网页视频页面是否容易被浏览器扩展识别、控制和导航。
本项目只适用于你自己拥有或已经获得授权的测试环境。
当前版本:2.3.3
本项目适用于防御性测试和授权场景下的网页视频流程分析。
你可以用它来:
- 测试你自己的网页视频平台;
- 检查视频控件是否过于容易被自动化;
- 调试课程或资源导航逻辑;
- 验证非视频资源是否会被正确处理;
- 改进服务端防刷和进度校验设计。
请不要使用本扩展绕过学习要求、伪造考勤、伪造视频进度,或违反任何平台规则。
Video Helper 可以在基于 Chromium 的浏览器上使用,包括:
- Google Chrome
- Microsoft Edge
- Atlas Browser
- 其他支持加载未打包扩展的 Chromium 内核浏览器
扩展首次安装后,Video Helper 会自动打开配置页面。
你可以配置:
- 允许测试的网址 / 域名;
- 等待时间上限;
- 扫描间隔。
页面控制面板只会在配置好的白名单网站上显示。
点击扩展图标后,会出现一个简单菜单:
- Open Configuration
- Open Status Panel
- Coming Soon
扩展弹窗只作为入口使用。真正的运行控制按钮会显示在网页中的页面控制面板里。
在白名单网站中,Video Helper 可以打开一个浮动控制面板。
面板包含:
- Scan Page
- Play Current Video
- Next
- Highlight Next
- Start
- Stop
- Clear Highlights
面板可以最小化。最小化后,页面角落会保留一个小的 Video Helper 按钮,点击后可以恢复面板。
Video Helper 会扫描当前页面中的:
- 可见的
<video>元素; - 疑似视频播放按钮;
- 疑似下一资源按钮。
它会避免识别自己的 UI 元素,并忽略常见的非视频按钮,例如:
开始答题答题测验考试作业练习quizexamtesthomeworkexercisequestion
这样可以减少在页面包含测验、练习、作业或考试按钮时的误判。
| 配置项 | 含义 | 默认值 |
|---|---|---|
Wait Limit |
打开资源后,最多等待多久寻找视频 | 180 秒 |
Scan Interval |
等待过程中,每隔多久扫描一次页面 | 15 秒 |
例如:
Wait Limit = 60
Scan Interval = 5
表示 Video Helper 最多等待 60 秒,并且每 5 秒扫描一次页面。
如果页面中存在原生“下一节 / 下一个”按钮,Video Helper 会优先尝试使用它。
如果页面中没有原生下一按钮,它会尝试通过以下方式解析下一个资源:
- 从当前 URL hash 中读取当前 activity ID;
- 扫描页面 DOM 中的课程或资源链接;
- 在资源列表中找到当前资源;
- 按顺序打开下一个资源。
这适用于某些资源没有显式“下一节”按钮的平台。

如果 Video Helper 可以轻松自动化你的网站视频流程,建议加强平台设计。
推荐的服务端校验包括:
- 不要信任纯前端进度值;
- 不要允许前端直接提交
completed=true; - 使用服务端观看会话;
- 校验心跳时间间隔;
- 校验视频进度连续性;
- 拒绝异常的大进度跳跃;
- 防止进度请求重放;
- 对异常行为做频率限制;
- 在服务端计算完成状态;
- 不要只依赖鼠标、焦点、可见性检测。
前端检测有价值,但不应该作为唯一可信来源。
- 修复测验 / 考试 / 作业按钮被误识别为播放按钮的问题。
开始答题不再被识别为播放按钮。- 播放识别不再使用泛泛的
start / 开始文案,除非它明确和视频播放有关。
- 修复自我识别问题。
- 扫描器不再识别 Video Helper 自己的面板、按钮、标签和进度 UI。
- 项目名称改为 Video Helper。
- 新增首次安装配置页面。
- 新增插件弹窗菜单。
- 新增白名单内才显示页面控制面板。
- 新增可最小化页面控制面板。
- 将
In Progress从页面中央移动到页面控制面板中。 - 将插件弹窗简化为配置窗口。
- 将 Liquid Glass 风格改为更清晰的高对比度界面。
- 改进下一按钮过滤逻辑。
- 新增可配置等待时间和扫描间隔。
- 新增手动
Next按钮。 - 新增基于路径的下一资源解析器。
