The extension will sit in your toolbar, detect video sources on the active page, and offer direct download links without routing traffic through third-party servers.
  • Detect embedded, streaming, and direct video sources on any webpage

Why Open Video Downloader

为什么选择Open Video Downloader

Videos on the modern web are served through adaptive streaming protocols, embedded players with proprietary JavaScript wrappers, and platform-specific delivery networks. Right-clicking a video rarely produces a usable save option, and most free download tools inject ads, harvest browsing data, or stop working the moment a site updates its player.
Open Video Downloader is being designed as a transparent, community-auditable solution to that problem. Because the source code is open, anyone can inspect exactly what the extension does with network requests and page data. The goal is to parse video sources from the active tab, present every available quality option, and hand the file directly to the browser's download manager with nothing in between.
现代网页上的视频通过自适应流媒体协议、带专有JavaScript封装的嵌入式播放器以及平台专属的分发网络提供。右键点击视频很少能得到可用的保存选项，而大多数免费下载工具会注入广告、窃取浏览数据，或者在网站更新播放器后立刻失效。
Open Video Downloader是为解决上述问题设计的透明、可经社区审计的方案。由于源代码开源，任何人都可以检查扩展对网络请求和页面数据的处理逻辑。项目目标是从当前活动标签页解析视频源，展示所有可用的画质选项，直接将文件交给浏览器的下载管理器，中间没有任何额外环节。

常见问题

When will Open Video Downloader be released? A release date has not been set. Sign up at the waitlist link above to be notified as soon as it is available.
Does it work on every website? The extension uses generic video detection rather than site-specific scripts, so it is designed to work broadly. Some sites with heavily obfuscated or DRM-protected streams may not be supported.
What video quality will it support? Quality options depend on what the website makes available. The extension will list every resolution and bitrate it can detect so you can choose the one you prefer.

About Online Video

关于在线视频

Online video now spans billions of hours of content across social networks, streaming services, educational platforms, news outlets, and personal sites. Despite this scale, most platforms lock playback inside proprietary players and offer no built-in option to save a file locally. Open Video Downloader is being built to give users a reliable, transparent way to save the videos they already have access to view, without depending on closed-source tools that may compromise privacy or stop working without warning.
目前在线视频覆盖了社交网络、流媒体服务、教育平台、新闻媒体和个人站点上数十亿小时的内容。尽管规模庞大，大多数平台都将播放限制在专有播放器内，不提供本地保存文件的内置选项。开发Open Video Downloader的目的是为用户提供可靠、透明的方式，保存他们已经有权访问的视频，无需依赖可能损害隐私或毫无预警停止工作的闭源工具。
