如何使用 blob url 下载视频?

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:

  1. 打开More ToolsDeveloper Tools
  2. 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>
    
  3. 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。
  4. 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":"
    
  5. 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": [
                     { ... ... ...
    
  6. 现在用你的 id 编写一个 url,XYZ如下所示:https://player.vimeo.com/video/XYZ

  7. 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)。
  8. 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>
    
  9. 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 -

  1. 右键单击视频,然后单击“检查元素”-

你会发现这样的代码

<div id="playerContainer" class="player-container full-screen-enabled" data-config="{&quot;is_360&quot;:false,&quot;duration&quot;:28617,&quot;scribe_widget_origin&quot;:true,&quot;heartbeatEnabled&quot;:true,&quot;video_url&quot;:&quot;https:\/\/video.twimg.com\/ext_tw_video\/844504104512749568\/pu\/pl\/e91Du5N2TZ09ZaW_.m3u8&quot;,&quot;disable_embed&quot;:&quot;0&quot;,&quot;videoInfo&quot;:{&quot;title&quot;:null,&quot;description&quot;:null,&quot;publisher&quot;:{&quot;screen_name&quot;:&quot;MountainButorac&quot;,&quot;name&quot;:&quot;Mountain Butorac&quot;,&quot;profile_image_url&quot;:&quot;https:\/\/pbs.twimg.com\/profile_images\/808318456701521920\/vBvlAASx_normal.jpg&quot;}},&quot;cardUrl&quot;:&quot;https:\/\/t.co\/SdSorop3uN&quot;,&quot;content_type&quot;:&quot;application\/x-mpegURL&quot;,&quot;owner_id&quot;:&quot;14120461&quot;,&quot;looping_enabled&quot;:true,&quot;show_cookie_override_en&quot;:true,&quot;visit_cta_url&quot;:null,&quot;scribe_playlist_url&quot;:&quot;https:\/\/twitter.com\/MountainButorac\/status\/844505243538931714\/video\/1&quot;,&quot;source_type&quot;:&quot;consumer&quot;,&quot;image_src&quot;:&quot;https:\/\/pbs.twimg.com\/ext_tw_video_thumb\/844504104512749568\/pu\/img\/FFt3qkbeOh0RlGfZ.jpg&quot;,&quot;heartbeatIntervalInMs&quot;:5000.0,&quot;use_tfw_live_heartbeat_event_category&quot;:true,&quot;video_loading_timeout&quot;:45000.0,&quot;status&quot;:{&quot;created_at&quot;:&quot;Wed Mar 22 11:05:14 +0000 2017&quot;,&quot;id&quot;:844505243538931714,&quot;id_str&quot;:&quot;844505243538931714&quot;,&quot;text&quot;:&quot;Took my Goddaughter to meet the pope.

2.将上述代码复制粘贴到 notepad++ 中。将所有&quot;"\/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

  1. 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

  1. 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。

  1. 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/
  2. 在浏览器中打开 URL。
  3. 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
  4. 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。
