blob下载问题的详细描述

我想用src url blob:https://www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386下载视频,但是不知道应该怎么做。

有没有下载这类视频的通用方法?

推荐的解决方法

我在Vimeo中找到了一个使用blob url下载视频的方法(读了这篇文章,我才知道做法)。我正在使用Google Chrome,具体步骤如下:

1、打开More Tools(更多工具)→Developer Tools(开发工具)

2、检查视频标签中是否有这样的东西:

<video preload="" src="/UploadFiles/2021-04-02/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX">

3、复制iframe标签的src(如果有的话)值,如http://player.vimeo.com/video/XYZ,如果你发现它可以复制,直接跳到第7点,否则按照步骤4,5,6继续操作。

4、现在在页面中找到这个字符串https://skyfire.vimeocdn.com/.../master.json"htmlcode">

(function(e,a){var t={"cdn_url":"https://f.vimeocdn.com","view":1,"request":{"files":{"dash":{"origin":"gcs","url":"https://48skyfiregce-a.akamaihd.net/.../master.json","cdn":"

5、复制上面的url字段中的链接到一个新的Chrome选项卡,例如https://48skyfiregce-a.akamaihd.net/.../master.json"htmlcode">

{
  "clip_id": XYZ,
  "base_url": "../",
  "video": [
         { ... ... ...

6、现在用id XYZ组合构造一个URL,如下所示:https://player.vimeo.com/video/XYZ

7、用最终的URL替换视频标签内的blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX(在上一步#6中创建的)。

8、现在可以发现,魔术般地,视频标签内的src字段已更改(如果没有,请尝试第7步多次)...

<video preload="none" src="/UploadFiles/2021-04-02/XXXXXXXXX.mp4">

最后,使用新的链接直接下载它,就像这样:https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4"color: #ff0000">其他的解决思路

这个答案是针对Twitter网址的 -

右键点击视频,然后点击检查元素 -

你会发现这样的代码

复制上面的代码,并粘贴到记事本++(Notepad++)中,然后用"替换所有的&quot;,用/替换所有和\/。 (使用CTRL + H)

从上面的JSON格式,可以看到video_url的值

https://video.twimg.com/ext_tw_video/844504104512749568/pu/pl/e91Du5N2TZ09ZaW_.m3u8

这里的问题是,在2016年8月1日之后,Twitter不再使用.mp4视频,而是转换为新的HLS,自适应流格式,带有.m3u8文件扩展名。

.m3u8文件基本上只是一个文本文的封装,它们非常小(300-500字节)。当您使用文本编辑器打开它们时,它们包含指向不同视频大小的链接

在记事本++(Notepad++)中打开文件m3u8,它会包含这样的代码

EXTM3U EXT-X-INDEPENDENT-SEGMENTS EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=256000,RESOLUTION=180x320,CODECS="mp4a.40.2,avc1.42001f"/ext_tw_video/844504104512749568/pu/pl/180x320/_Z42SY5zwMlLdFYx.m3u8 EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=832000,RESOLUTION=360x640,CODECS="mp4a.40.2,avc1.42001f"/ext_tw_video/844504104512749568/pu/pl/360x640/-Phfjbbx2yinirLi.m3u8

根据您需要的分辨率从上面复制对应的链接。重复相同的步骤,直到有.ts文件。下载.ts文件(视频文件)。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
