Automatically create thumbnails for posts when images are uploaded and the post is saved. Includes support for Oembed.
When a post is saved, if no featured image has been selected, attachments are scanned and the first one is used. If there are no attachments, the post content is scanned. If an image is found in the content then it is used otherwise if there are video oembeds, they are used.
Note, we’re also on github in case you want to add some pull requests or a fork!

Requires the Advanced Custom Fields plugin. Output can be selected as HTML embed, URL, or data object. Includes settings for preview and output resolution and will accept any provider registered in WordPress.
With the news that ACF V5 includes a built-in oEmbed field type, we’re discontinuing further development of this plugin. The plugin will remain online for legacy V4 support to those that haven’t upgraded, but only essential updates will be released.
<h4>Compatibility</h4>
This add-on will work with:
<ul>
<li>Advanced Custom Fields version 4 and up</li>
<li>Repeater Field</li>
</ul>

Advanced Custom Fields: oEmbed Field
