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.

<!DOCTYPE html>
    <h1>Hello World!</h1>
    <p>This is my <strong>first</strong> website, I hope you <em>enjoy</em> it.</p>
    <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>
      <li>Indomie <br><img src="" alt="picture of instant ramen"/></li>
      <li>Swallow <br><img src="" alt="picture of nigerian swallow/fufu" /></li>
      <li>Jollof Rice <br><img src="" alt="picture of Jollof Rice" /></li>
    <h3> Favourite film franchises (in order) </h3>
      <li>Jurassic Park</li>
      <li>Harry Potter</li>
    <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:
        <li> Carnegie Mellon Univeristy </li> 
        <li>University of California: Irvine</li> 
      <video src="" width="360" height="200" controls>
      video not supported
    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.
