The video content doesn’t work

Question

<video controls>
<source src="video.mp4" type="video.mp4">
</video>
Why video doesn’t play?

Answer 1

Provide the correct link for the video. "video.mp4" might not be the exact link.
And the type is wrong. It's "video/mp4", not "video.mp4"

Answer 2

So I can see the window on the website, but the player doesn’t work
