Why isn't this youtube shortcode working?

echo do_shortcode('');

Is merely printing

" 

out onto the page.

I know I can display the video with html with

<iframe src="" width="560" height="315" frameborder="0" allowfullscreen></iframe>

but I'm trying to leverage wordpress' built-in methods. How do I do this?

I think this is what you are looking for:

<?php echo wp_oembed_get('https://www.youtube/watch?v=vZBCTc9zHtI'); ?>

For more details check this documentation.

If you just want to embed a video in the content area, WordPress does this pretty elegantly with oembeds. You just need to paste the URL into the editor and save the post. As long as the embeds are supported, WordPress will work its magic and format your embed.

Your call to do_shortcode() doesn't make sense. As posted, your code is saying, "look through this youtube URL string and run the shortcodes found within it".

do_shortcode() 

Is used to printout shortcode. And you are writting URL in it. No use of this. Try to implement

wp_oembed_get( $url, $args )

This will work for you. So your code will

wp_oembed_get('https://www.youtube/watch?v=vZBCTc9zHtI')

or if you want to specify width then

wp_oembed_get('https://www.youtube/watch?v=vZBCTc9zHtI', array('width'=>400))

It is not working because using a youtube url in the content has nothing to do with shortcodes, which is why it doesn't work when you try to call do_shortcode, what it actually does is to envoke the oEmbed protocol which is a very different thing.

There is an oEmbed shorcode and you probably can do do_shortcode('[oEmbed youtube.....]') but as other answers pointed out, there is an explicit API for that and using the shortcode is the long way to do that.

The most important thing to keep in mind in what you are trying to do, is that oEmbed sends a request to youtube servers and waits to a reply, which means that without some caching this kind of code will slow down the page on every load.
