[embed] shortcode doesn't work with do_shortcode()

[jtsternberg]

It would be preferable to use the [embed] shortcode through do_shortcode rather than apply_filters( 'the_content',... in order to avoid sharing plugins, related posts plugins etc appending content to something that could simple be post meta, i.e. looking to convert a youtube url to a video.

FWIW, you can do it through WP_Embed::run_shortcode().

No, that method doesn't work because it's not a proper static method and uses the $this variable which is unavailable. I CAN do

	$embed = new WP_Embed();
	$video = $embed->run_shortcode( '[embed width="890"]'. esc_url( $video_url ) .'[/embed]' );

But that definitely seems like overkill to me.

Ok, digging a bit further, I realized the WP_Embed class is initialized as a global variable so is accessible to me via

$GLOBALS['wp_embed']->run_shortcode( '[embed width="890"]'. esc_url( $video_url ) .'[/embed]' );

So pardon my interruption here. :)

Curious, should we document that in the codex?

Ok, another thought regarding the point of this ticket originally: it seems plausible that we could still enable this featured through do_shortcode() by checking for the [embed] shortcode, and then running this method. I'll throw up a patch if I get a chance.

Well, yes, working code would be global $wp_embed; $wp_embed->run_shortcode( $whatever );. I'd check out the docs for the method - I think you'll find them helpful.

Simple check for the [embed] shortcode that allows filtering via do_shortcode()
