oEmbed, thumbnails and wordpress

Question

Wordpress has wp_oembed_get, which I use to get rich media content with embed.ly. I've previously used oEmbed api calls such as this. As you can see it provides thumbnail_url, which I like to use instead of embedding the video. How can I do this with wordpress?

Thanks!

Answer 1

Use the oembed_dataparse filter to modify the resulting HTML output by any given oembed call.

Example:

add_filter('oembed_dataparse','test',10,3);

function test($return, $data, $url) {
    if ($data->provider_name == 'YouTube') {
        return "<img src='{$data->thumbnail_url}'>";
    }
    else return $return;
}

Then putting this in a post:

[embed]http://www.youtube.com/watch?v=oHg5SJYRHA0[/embed]

Will give you a picture of Rick Astley instead of a flash video of him. :)

Edit: Note that WordPress caches oEmbed results in postmeta. So after making your code, you'll have to go and Update a post for it to know to go re-get the oEmbed data and have code like this take effect. In case you want to do testing and such.
