Haiku Deck for WordPress

Register Haiku Deck as an oEmbed content provider

EP4 Corporation

EP4 More Embeds adds support for more embedded content on your website. It makes use of WordPress <code>wp_oembed_add_provider</code> 
for providers supporting oEmbed, and <code>wp_embed_register_handler</code> for the other providers who still allow embedding 
content on other websites even though it’s not through the oEmbed feature.
At the moment, the following providers are supported:
<ul>
<li>Bandcamp</li>
<li>Box.com</li>
<li>Twitch.TV</li>
<li>VEVO</li>
</ul>

EP4 More Embeds
