Video Element

Hello everyone,
I was working on a personal project and trying to insert a video into it. However, the video doesn’t play, but it doesn’t display the “video not supported” text either. Is there a way this could be fixed? the video element is right near the bottom.

    <h2> About me </h2>
    <h3> Ambition </h3>
    <p>My ambition is to become a software engineer. I am taking the <br>Full-stack development course on <strong>codecademy</strong> to help me achieve that goal. <br>My dream job is one at Google.</p>
    <h3> Favourite foods </h3>
    <ul>
      <li>Indomie <br><img src="https://th.bing.com/th/id/R.c7972249bbc5b5a976caa95b4fd8a219?rik=00vDc8tDAvE0Vw&pid=ImgRaw&r=0" alt="picture of instant ramen"/></li>

    <h3> Favourite film franchises (in order) </h3>
    <ol>
      <li>Jurassic Park</li>
      <li>Harry Potter</li>
    </ol>
    <h3> College </h3>
    <p> My preffered college is MIT, though that is a serious reach for me. I think a more realistic goal would definitely be:
      <ul> 
        <li> Carnegie Mellon Univeristy </li> 
        <li>University of California: Irvine</li> 
      </ul>

      video not supported
      </video>
    Both are very good schools that I would love to go to.</p>

As far as I’m aware, the HTML video tag doesn’t support using YouTube videos as a source. You would need to download the video as an mp4 or the like, or else use YouTube’s built in embed tags.
