m3u8 视频在线提取工具(English version)

image.png

工具在线地址,推荐使用 chrome 浏览器。

研发背景

  • m3u8视频格式简介

    • m3u8视频格式原理:将完整的视频拆分成多个 .ts 视频碎片,.m3u8 文件详细记录每个视频片段的地址。
    • 视频播放时,会先读取 .m3u8 文件,再逐个下载播放 .ts 视频片段。
    • 常用于直播业务,也常用该方法规避视频窃取的风险。加大视频窃取难度。
  • 鉴于 m3u8 以上特点,无法简单通过视频链接下载,需使用特定下载软件。

    • 但软件下载过程繁琐,试错成本高。
    • 使用软件的下载情况不稳定,常出现浏览器正常播放,但软件下载速度慢,甚至无法正常下载的情况。
    • 软件被编译打包,无法了解内部运行机制,不清楚里面到底发生了什么。
  • 基于以上原因,开发了本工具。

工具特点

  • 无需安装,打开网页即可用。
  • 强制下载现有片段,无需等待完整视频下载完成。
  • 操作直观,精确到视频碎片的操作。

功能说明

【解析下载】输入 m3u8 链接,点击下载视频。
【跨域复制代码】当资源出现跨域限制时,点击复制页面代码,在视频页面的控制台输入。将工具注入到视频页面中,解决跨域问题。
【重新下载错误片段】当部分视频片段下载失败时,点击该按钮,重新下载错误片段。
【强制下载现有片段】将已经下载好的视频片段强制整合下载。可以提前观看已经下载的片段。该操作不影响当前下载进程。
【片段Icon】对应每一个 .ts 视频片段的下载情况。「灰色」:待下载,「绿色」:下载成功,「红色」:下载失败。点击红色 Icon 可重新下载对应错误片段。

使用说明

  • 打开视频目标网页,鼠标右键「检查」,或者「开发者工具」,或者按下键盘的「F12」键
  • 找到 network,输入 m3u8,过滤 m3u8 文件。
  • 刷新页面,监听 m3u8 文件。

  • 找到目标m3u8文件,查看文件内容,是否符合格式。

    • 如下为索引文件,不是真正的视频 m3u8 文件

    • 一般内容有许多 ts 字眼的文件才是我们需要的视频 m3u8 文件。

  • 拷贝这个 m3u8 文件的链接。

  • 打开工具页面,输入链接,点击「解析下载」。
  • 出现片段 Icon,则证明操作成功,耐心等待视频下载。
  • 片段全部下载成功,将触发浏览器自动下载,下载整合后的完整视频。
  • 如果有片段下载失败,则点击对应片段,或点击「重新下载错误片段」按钮。重新下载错误片段。

异常情况

【无法下载,没有显示片段Icon】

  • 一般由于跨域造成。
  • 点击「跨域复制代码」按钮。
  • 打开视频目标网页的「开发者工具界面」,找到 console 栏。

  • 粘贴刚刚复制的内容,回车。
  • 滚动页面到底部,发现工具显示在底部。然后在注入的工具中正常使用。

【下载后的视频资源不可看】

  • 网站对视频源进行了加密操作。不同的视频网站有不同的算法操作。无法通用处理。
  • 一般网站不会有这种情况。爱奇艺,腾讯等大视频网站才会有该安全措施。

      Hello to the Etaishun Owner,

      I am Eric, and for a moment, consider this scenario:

      - Someone searches online and arrives at Etaishun.  
      - They spend a short time reviewing your site. They might be curious, but not fully decided.  
      - Then, they leave and look at other options.  
      - In the end, you received a visitor, but no meaningful connection.

      This situation occurs often. It’s very common for most site visitors to leave without taking further action.

      You can address this:

      Web Visitors Into Leads is a resource that operates on your site, ready to gather each visitor’s name, email address, and phone number. It will alert you right when they show interest, allowing you to connect with them while they are still exploring your site.

      Prompt contact makes a difference. Engaging with someone shortly after they visit is far more effective than waiting until much later.

      Moreover, once you have their phone number, you can begin a text-based conversation. If they are not ready to move forward at that exact moment, you can maintain contact by sharing helpful information later on.

      Everything described is straightforward and practical.

      Please visit the link above to see how Web Visitors Into Leads can benefit your business. You may find yourself connecting with significantly more interested individuals soon.

      Eric

      P.S. Web Visitors Into Leads provides a no-cost evaluation period. It also supports various communication methods. There may be potential clients interested in speaking with you right now, so don’t let them slip away.

      Hello to the Etaishun Owner,

      I am Eric and I recently came across your website at Etaishun. I found it after a search, so your visibility seems to be working well.

      Your content looks helpful.

      However, one thing might be missing:

      A simple, prompt way for visitors to connect with you.

      Research suggests that many visitors leave a site quickly without providing any contact information. Once they go, there’s no way to follow up.

      Consider this approach:

      Web Visitors Into Leads is a tool that operates on your site, ready to gather each visitor’s name, email address, and phone number. You will know as soon as someone shows interest, allowing you to speak with them while they’re still viewing your site.

      Once you have their phone number, you can also begin a text conversation. If they aren’t ready to engage at that exact moment, you can maintain communication later by sharing additional updates or simply checking in.

      Everything described is straightforward to implement and may help improve your interactions with potential contacts.

      Please visit https://actionleadgeneration.com to learn more about what Web Visitors Into Leads can do for you. It could help you connect with more interested individuals right now.

      Eric

      P.S. Web Visitors Into Leads includes a trial period and supports international communication. There may be individuals ready to speak with you now, so please don’t miss the opportunity.

      Hello to the Etaishun Manager,

      I am Eric, and I recently discovered your website Etaishun in the search results.

      Your site is visible online and the content is solid.

      However, there’s one area that may help improve results:

      When visitors arrive at Etaishun, many may look around briefly, then leave without taking further action. Research suggests most visitors exit quickly, and you never learn who they were or how to reach them.

      You can change that.

      Consider using Web Visitors Into Leads. This tool operates on your site and is ready to securely collect each visitor’s name, email, and phone number. It informs you right away when someone shows interest, so you can connect with them while they are still on your website.

      Prompt and meaningful outreach can make a substantial difference. Additionally, once you have a visitor’s phone number, you can begin a friendly text conversation. Even if they aren’t ready at that moment, you can keep in touch over time with relevant updates and useful information.

      This approach is easy to implement and can help you engage more effectively with interested individuals.

      Visit the link above to see what Web Visitors Into Leads can do for your business. By reaching out promptly, you may find that more visitors become engaged prospects.
