is <audio> and <video> just for local files?

Question

or could I :

<video>
<iframe>
</video>

just for semantic reasons...

Answer 1

No, it's not a semantic element, but it's also not for local files. It's for files that can be accessed with a URL (http://www.example.com/myvideo.mp4)

The browser does not have access to files on a user's computer unless the file was copied into local storage specifically by the user.

I don't see why you would ever need to use an iframe, the <video> tag is much more efficient.

Answer 2

audio and video tags are for server files, not local files.
It's only for local file, if the html run from your local machine.

Answer 3

well, you could just use iframe, or if you like youtube, click embed
