How do we download a blob url video

I'm using this blog to publish video tutorials about technology, programming, development tools and sometimes video games as well.

This is NOT blob, it's just a video file.

this isn't a blob url. IT'S JUST A NORMAL VIDEO LINK

Do you have any idea of what a URL blob is?

Man you are really good. I struggled with this problem for 2 weeks. I did not know that in the phone version the video does not have autoload, because of this it turns out to receive data about the video on the network.

friend help me, I'm trying to do this with the YouTube video, and when I open the "videoplayback" it only plays 4 seconds of the video and then mysteriously pauses, I've tried everything and it's not the computer or the browser, because I also tested it with Firefox... do you know what this could be?
