Displaying Videos

Displaying a video might be just as simple as adding this to your README.md

<video width="560" height="240" controls>
  <source src="https://sample-videos.com/video123/mp4/480/big_buck_bunny_480p_1mb.mp4" type="video/mp4">
  Your browser does not support the video tag.
</video> 

This will work on most modern browsers nowadays which is great.

However there's no way to embed a vimeo or youtube video using the video tag that I know of.

Using vimeo or youtube iframe embeds works fine of course - here's a youtube example:

<iframe width="560" height="315" src="https://www.youtube.com/embed/bTqVqk7FSmY" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>

And here's a vimeo example:

<iframe src="https://player.vimeo.com/video/143418951" width="560" height="315" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
<p><a href="https://vimeo.com/143418951">&quot;View From A Blue Moon&quot; Trailer</a> from <a href="https://vimeo.com/johnjohnflorence">John John Florence</a> on <a href="https://vimeo.com">Vimeo</a>.</p>

"View From A Blue Moon" Trailer from John John Florence on Vimeo.

However, that gives you all their branding and ads and so on and limits your ability to syle what you see.
