I am trying to download video with src url blob:https%3A//www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386.

Is there a process that can be followed to download all this type of videos?

  • If you want to download youtube videos use extenstions like Video Downloadhelper (Firefox) – Ganesh R. Jan 30 '16 at 22:42
  • i want to download from vimeo url. – vinesh Jan 31 '16 at 2:48
  • Vinesh, try navigating to vimeo website and start playing the video you require to download. Video DownloadHelper will detect it and give you an option to download it. I tried it. – Ganesh R. Jan 31 '16 at 6:09
  • No Luck. when I started playing video, I saw multiple video suggestion from the extension you mentioned each of around 2 MB. when I downloaded a part, I was not able to play that small file. I was getting error that file is corrupt. – vinesh Feb 1 '16 at 6:42
  • put the link in comments – Ganesh R. Feb 1 '16 at 15:45

I found a way to download the video with blob url in Vimeo (reading here i understood how doing it). I write the simple steps here. I'm using Google Chrome:

  1. Open the More ToolsDeveloper Tools
  2. Check if in the video tag there is something like this:

    <video preload="" src="blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"></video>
  3. Copy the src of the iframe tag, if any, something like http://player.vimeo.com/video/XYZ if you found it you can go straight to the point 7, otherwise follow steps 4, 5, 6.
  4. Now look for this string https://skyfire.vimeocdn.com/.../master.json?base64_init=1 inside the page (using the Developer View), you should found it inside a 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":"
  5. Copy the link inside the url field on a new Chrome tab, for example https://48skyfiregce-a.akamaihd.net/.../master.json?base64_init=1 end open it with a browser, it will open you a json file like this:

        "clip_id": XYZ,
        "base_url": "../",
        "video": [
                     { ... ... ...
  6. Now compose a url with your id XYZ like this: https://player.vimeo.com/video/XYZ

  7. Replace blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX inside the video tag with that last url (the one created in the previous step #6).
  8. Now you will notice that magically the src field inside of the video tag changed (if it does 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>
  9. Use that new link to dowload it directly, it's something like this: https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg

    Impressive. How have you figured this out? – gronostaj Oct 2 '16 at 11:24

    In step 7, what do you mean with "that last url inside the html"? – joaorodr84 Feb 6 '17 at 23:32

    Works perfectly, but the trick is sometimes you have to replace the "src" value multiple times to get the download link generated. – Ashrith Feb 17 '17 at 3:23

    Currently, for Vimeo it is much easier and doesn't require all the steps. Simply open a Vimeo video, find the <video> tag in the dev tools DOM structure and change the src attribute from blob:... to x. Nothing will happen - this is ok. Now change it again, to y. Chrome will convert it 'magically' to the URL like in step 8 or 9. :-) – StanE Jan 4 '18 at 18:31

    @StanE it works like a charm, in Firefox too, and is definitely faster... – ling Feb 27 '18 at 3:42
<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">

I also had blob: URL in video/@src, but by watching Developer tools > Network during playback it turned out that video/source/@src was URL for m3u8 playlist.

An m3u8-backed video can be readily downloaded by either:

  • 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 sounds like the binary you want to get but there might be easier way to get the video. Just check out Network tab in Dev tools while you play the video to see what you are actually fetching.

    Works on my machine! And you can supply multiple kinds of stream inputs with -i <URL> -i <URL> -i <URL> to merge video, audio, and subtitles all into one output :) – mcandre Nov 25 '18 at 17:31
  • @mcandre Yes, that's a good tip. You can also possibly find m3u8 metalist (i.e. m3u8 file referring other m3u8 files) and ffmpeg will download and merge it properly, so you don't need to manually specify multiple inputs -i. – Vlastimil Ovčáčík Nov 26 '18 at 13:30

    Confirmed that this still works! – oscilatingcretin Mar 25 at 23:50

This answer is for Twitter URLs -

  1. Right click on the video and click Inspect Elements -

You'll find a 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.

2.Copy Paste above code in notepad++. Replace all the &quot; with " and \/ wth / in notepad++. (Use CTRL+H)

You'll get something like

From above JSON format, see the value video_url


The issue here is, after August 1st, 2016, Twitter is no longer using .mp4 videos, but converting to a new HLS, adaptive-streaming format, with a .m3u8 file extension.

.m3u8 files are basically just a text file wrapper, they are super small (300-500 bytes), and when you open them with a text editor, they contain links to different video sizes

  1. Open the file m3u8 in notepad++, it would contain code like this

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

  1. Copy the respective link from above as per your resolution need. Repeat the same step until you have .ts file. Download the .ts file (the video file).

  • What do you mean, "you'll get something like" -- from where? – User Mar 26 '17 at 1:09
  • @User from the code above it which starts like <div id="playerContainer" – Pirate X Mar 26 '17 at 10:51
  • 3
    Hey, in step 4, what do you mean by "copy the respective link" ? It isn't a valid URL, and I can't find how to get the video with it. EDIT : OK, right, I found it. You should mention that you have to put "video.twimg.com" before it and access the URL. – Hey Jun 17 '17 at 10:37
  • If you can't find the id="playerContainer" element look for og:video:url and open the url in the content, and inspect the source of that. – guillefix Mar 7 '18 at 21:01
  • Another way to do it on twitter is to run document.querySelector('video').src in your browser developer tools console tab. – Farzad YZ Oct 14 '18 at 20:16

I found another way to download a video with blob url in Vimeo (see the other answer in this page).

This solution is suitable only if you want just the video without the sounds!

So, if you want to download just a Vimeo video (often without sounds), I can confirm that this Google Chrome extension works really good: Flash Video Downloader.
