如何使用 blob url 下載影片?

我正在嘗試使用 src url 下載影片blob:https%3A//www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386

是否有一個可以遵循的流程來下載所有此類影片?

答案1

我找到了一種下載影片的方法blob urlVimeo閱讀這裡我明白怎麼做)。我在這裡寫下簡單的步驟。我正在使用谷歌瀏覽器:

  1. 打開More ToolsDeveloper Tools
  2. 檢查影片標籤中是否有這樣的內容:

    <video preload="" src="blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"></video>
    
  3. 複製 iframe 標籤的 src,如果有的話,類似http://player.vimeo.com/video/XYZ如果找到了就可以直接進入第 7 點,否則按照步驟 4、5、6 進行操作。
  4. https://skyfire.vimeocdn.com/.../master.json?base64_init=1現在在頁面內尋找此字串(使用開發人員視圖),您應該在 javascript 函數內找到它,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. 將 url 欄位中的連結複製到新的 Chrome 標籤上,例如https://48skyfiregce-a.akamaihd.net/.../master.json?base64_init=1使用瀏覽器開啟它,它將開啟一個如下所示的 json 檔案:

    {
        "clip_id": XYZ,
        "base_url": "../",
        "video": [
                     { ... ... ...
    
  6. 現在用你的 id 寫一個 url,XYZ如下所示:https://player.vimeo.com/video/XYZ

  7. 將影片標籤內的內容替換blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX為最後一個 URL(在上一個步驟 #6 中建立的 URL)。
  8. 現在您會注意到視訊標籤內的 src 欄位神奇地發生了變化(如果沒有變化,請多次嘗試步驟 7)...

    <video preload="none" src="https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg"></video>
    
  9. 使用該新連結直接下載,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>

我也有blob:URL video/@src,但透過在播放期間觀看Developer tools>Network發現這video/source/@src是播放清單的 URL m3u8

m3u8可以透過以下任一方式輕鬆下載支援的影片:

  • 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 聽起來像是您想要獲取的二進位文件,但可能有更簡單的方法來獲取視訊。只需在播放影片時查看開發工具中的「網路」標籤即可查看實際取得的內容。

答案3

這個答案適用於 Twitter URL -

  1. 右鍵單擊視頻,然後單擊檢查元素 -

你會發現這樣的程式碼

2.將上面的程式碼複製貼上到notepad++中。更換所有&quot;"\//在記事本++中。 (使用 CTRL+H)

你會得到類似的東西

從上面的JSON格式,看到值視訊位址

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

這裡的問題是,2016 年 8 月 1 日之後,Twitter 不再使用 .mp4 視頻,而是轉換為新的 HLS、自適應流格式,具有.m3u8檔案副檔名。

.m3u8 檔案基本上只是一個文字檔案包裝器,它們非常小(300-500 位元組),當您使用文字編輯器打開它們時,它們包含指向不同視訊大小的鏈接

  1. 在notepad++中開啟檔案m3u8,它會包含這樣的程式碼

EXTM3U EXT-X-獨立段 EXT-X-STREAM-INF:程式 ID=1,頻寬=256000,解析度=180x320,CODECS=“mp4a.40.2,avc1.42001f” /ext_tw_video/844504104512749568/pu/pl/180x320/_Z42SY5zwMlLdFYx.m3u8 EXT-X-STREAM-INF:程式 ID = 1,頻寬 = 832000,解析度 = 360x640,CODECS =“mp4a.40.2,avc1.42001f” /ext_tw_video/844504104512749568/pu/pl/360x640/-Phfjbbx2yinirLi.m3u8

  1. 根據您的解析度需要複製上面的相應連結。重複相同的步驟,直到完成.ts文件。下載.ts文件(影片檔)。

答案4

這是來自的 blob 視頻Facebook。需要最低限度的技術專業知識。

  1. 在影片中,點擊右上角的三個點然後單擊'複製連結'。連結將如下所示: https://fb.watch/1F3iBykxNf/
  2. 在瀏覽器中開啟網址。
  3. 現在您可以右鍵單擊影片命中框。 右鍵單擊影片命中框,然後按一下'複製當前時間的影片 URL'。 URL 將如下所示: https://www.facebook.com/686268088027568/videos/784217565526864/?t=0
  4. 將該 URL 貼到https://fbdown.net/。對我來說,我可以獲得一個 mp4 影片。

我與 fbdown.net 沒有關係。
