我正在尝试使用 src url 下载视频blob:https%3A//www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386。
是否有一个可以遵循的流程来下载所有此类视频？
答案1
我找到了一种方法来下载视频（blob url阅读Vimeo这里我明白该怎么做了。我在这里写下简单的步骤。我使用的是 Google Chrome：
- 打开
More Tools→Developer Tools 检查视频标签中是否有如下内容：
<video preload="" src="blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"></video>- 复制 iframe 标签的 src（如果有），
http://player.vimeo.com/video/XYZ如果找到，则可以直接转到第 7 点，否则请按照步骤 4、5、6 进行操作。 https://skyfire.vimeocdn.com/.../master.json?base64_init=1现在在页面内查找这个字符串（使用开发人员视图），你应该在 javascript 函数中找到它，如下所示：(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?base64_init=1","cdn":"在新的 Chrome 选项卡上复制 url 字段内的链接，例如
https://48skyfiregce-a.akamaihd.net/.../master.json?base64_init=1使用浏览器打开它，它将打开一个如下 json 文件：{ "clip_id": XYZ, "base_url": "../", "video": [ { ... ... ...现在用你的 id 编写一个 url，
XYZ如下所示：https://player.vimeo.com/video/XYZ- 将视频标签内部替换
blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX为最后的 URL（在上一步#6 中创建的 URL）。 现在您会注意到视频标签内的 src 字段神奇地发生了变化（如果没有，请多次尝试步骤 7）...
<video preload="none" src="https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg"></video>使用该新链接直接下载，如下所示： https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg
答案2
<video src="blob:https://www.example.tv/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx">
<source src="https://cdn.example.tv/api/media/tv/xyzxyz/index" type="application/x-mpegurl">
</video>
我也在blob:中设置了 URL video/@src，但在播放过程中观看Developer tools>Network后发现那video/source/@src是播放列表的 URL m3u8。
m3u8可以通过以下任一方式轻松下载支持的视频：
ffplay -i "https://cdn.example.tv/api/media/tv/xyzxyz/1080/index.m3u8"ffmpeg -i "https://cdn.example.tv/api/media/tv/xyzxyz/1080/index.m3u8" -codec copy file.mkv
tl;dr - blob URL 听起来像是您想要获取的二进制文件，但可能有更简单的方法来获取视频。只需在播放视频时查看 Dev 工具中的“网络”选项卡，即可查看您实际获取的内容。

这个答案是关于 Twitter URL 的 -
- 右键单击视频，然后单击“检查元素”-
你会发现这样的代码

2.将上述代码复制粘贴到 notepad++ 中。将所有"和"和\/wth/在 notepad++ 中。（使用 CTRL+H）
你会得到类似

从上面的 JSON 格式中，查看值视频网址
https://video.twimg.com/ext_tw_video/844504104512749568/pu/pl/e91Du5N2TZ09ZaW_.m3u8
这里的问题是，2016 年 8 月 1 日之后，Twitter 不再使用 .mp4 视频，而是转换为新的 HLS 自适应流媒体格式，具有.m3u8文件扩展名。
.m3u8 文件基本上只是一个文本文件包装器，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 notepad++ 中打开文件 m3u8，它将包含如下代码
EXTM3U EXT-X-独立段 EXT-X-流-INF：程序ID=1，带宽=256000，分辨率=180x320，CODECS="mp4a.40.2，avc1.42001f" /ext_tw_video/844504104512749568/pu/pl/180x320/_Z42SY5zwMlLdFYx.m3u8 EXT-X-STREAM-INF：程序ID=1，带宽=832000，分辨率=360x640，CODECS="mp4a.40.2，avc1.42001f" /ext_tw_video/844504104512749568/pu/pl/360x640/-Phfjbbx2yinirLi.m3u8
- 根据你的分辨率需求，从上面复制相应的链接。重复相同的步骤，直到你得到.ts文件。下载.ts文件（视频文件）。
答案4
这是来自的 blob 视频Facebook. 需要最低限度的技术专长。
- 在视频上，点击右上角三个点并点击'复制链接'。链接将如下所示： https://fb.watch/1F3iBykxNf/
- 在浏览器中打开 URL。
- 现在您可以右键单击视频热区。 右键单击视频命中框，然后点击'复制当前时间的视频 URL'。URL 看起来将类似于以下内容： https://www.facebook.com/686268088027568/videos/784217565526864/?t=0
- 将该 URL 粘贴到https://fbdown.net/。我能够获得 mp4 视频。
我与 fbdown.net 没有任何关系。
