It can't just be a url link.
First is you need a player installed.
Then you would take a hint from the existing video tags
Taking from youtube.
The trick is you need to find a player that works on your site.
Something like
<video width="320" height="240" controls>
<source src="https://www.outdoorking.com/forum/videos/TV%20ADS/TV%20ADS.html" type="video/mp4">
</video>
But it should be the actual file name not a html page.
