Video download problem of blob type URL

A detailed description of the BLOB download problem
I want to use the SRC url blob:https%3A//www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386 download video, but I don't know how to do it.
Is there a general way to download this kind of video?

Recommended solutions
I found a way to download a video using the blob url in Vimeo (I didn't know how until I read this article). I'm using Google Chrome. Here are the steps:

    open More Tools> Developer Tools check if there is something like this in the video tag:

    <video preload="" src="blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"></video>
    

    Copy the iframe SRC (if any) value of the label, such as http://player.vimeo.com/video/XYZ , if you find that it can be replicated, jump straight to point 7, otherwise in accordance with the step 4 and 6 to continue operating. Now find the string in the page https://skyfire.vimeocdn.com/... /master.json?Base64_init =1(using the Developer View), it should be found in the javascript function, like this:

    (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":"
    

    Force a.akamaihd.net/... copy the link from the url field above to a new Chrome TAB, such as https://48skyfiregce-a.akamaihd.net/... /master.json?Base64_init =1, then open it with a browser, it will open a json file like this:

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

    Use id now XYZ combination structure a URL, as shown in the following: https://player.vimeo.com/video/XYZ are replaced with the final URL video tag within the blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX (created in the previous step # 6). Now you can see that, magically, the SRC field inside the video tag has changed (if not, try Step 7 multiple times)...

    <video preload="none" src="https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg"></video>
    

    Finally, using the new link to download it directly, like this: https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg

Other solutions
The answer is for the Twitter url -

    right click on the video, then click check element -

You'll find code like this

<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.

Copy the above code and paste it into Notepad++ (Notepad++), then replace all & with "; quot; , replace all and \/ with /. (use CTRL + H)
You'll get something like this

From the JSON format above, you can see the value of video_URL

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

The problem here is that after August 1, 2016, Twitter stopped using.MP4 video and instead converted to a new HLS, adaptive streaming format with a.m3u8 file extension.

The.m3u8 files are basically just a wrapper around the text, and they are very small (300-500 bytes). When you open them with a text editor, they contain links to different video sizes

    in Notepad++ (Notepad++) open the file m3u8, which will contain the code

EXTM3U EXT-X-INDEPENDENT-SEGMENTS EXT - X - STREAM - INF: PROGRAM - ID = 1, BANDWIDTH = 256000, RESOLUTION = 180 x320 CODECS = "mp4a. 40.2, avc1.42001 f"/ext_tw_video/844504104512749568/pu/pl/180 x320/_Z42SY5zwMlLdFYx m3u8 EXT - X - STREAM - INF: PROGRAM - ID = 1, BANDW IDTH = 832000, 360 x640 RESOLUTION =, CODECS = "mp4a. 40.2, avc1.42001 f"/ext_tw_video/844504104512749568/pu/pl/360 x640/- Phfjbbx2yinirLi. M3u8

    copy the corresponding link from above according to the resolution you need. Repeat the same steps until you have a.ts file. Download the.TS file (video file).
