HTML5 Video Streaming with Blob Urls. Last updated. I read that entire file using the FileReader API and then created a Blob URL out of it so that it can be used in the HTML5 video tag. It turns out that I can skip FileReader completely and create a blob Url out of the user provided video instantly. This url is then assigned to the video. An Introduction To JavaScript Blobs and File Interface. A blob:// URL to a blob can be obtained using the createObjectURL object. A blob can be very large i.e., can contain audio and video data too. They can be created dynamically and using blob URLs they can be used as files. You can use them in many different ways to make them more. I would like to download a video from Dailymotion but Free Download Manager says the video url is unrecognised. The url begins with the word blob and then continues normally. Evidently it is 'blob' at the beginning which is causing the problem. Install the Video DownloadHelper extension on Firefox browser. With DownloadHelper activated, navigate to the webpage containing the video that you want to download. Once the video is streaming, click on the DownloadHelper icon. It will give you a list of all file formats available on the current video.

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:- Open the
More Tools
→Developer Tools
- Check if in the video tag there is something like this:
- 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. - 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: - 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: - Now compose a url with your id
XYZ
like this:https://player.vimeo.com/video/XYZ
- 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). - Now you will notice that magically the src field inside of the video tag changed (if it does not, try step 7 multiple times)...
- 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

This answer is for Twitter URLs -
- Right click on the video and click Inspect Elements -
You'll find a code like this
2.Copy Paste above code in notepad++. Replace all the
"
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
- 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
- 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).

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.

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.
