Thumbnail provider

Embed Privacy implemented an easy usable method to create custom thumbnail providers starting with version 1.9.0. To implement a custom thumbnail provider, extend the abstract class epiphyt\Embed_Privacy\thumbnail\provider\Thumbnail_Provider and implement the interface epiphyt\Embed_Privacy\thumbnail\provider\Thumbnail_Provider_Interface. (See also the blog post about Embed Privacy’s thumbnail generation for more information regarding the abstract class and interface.)

In it, you just need to define how to get the thumbnail and the associated embed ID. You can find a basic implementation for Vimeo on GitHub.

Then, use the filter embed_privacy_thumbnail_providers to register your custom thumbnail provider.
