@Everybody: Just use "grav-plugin-youtube" instead.

This plugin is functionally dead. Courtesy the frontpage, it's unlikely to ever be resurrected:

This plugin is outdated. It does not work with Grav v1.x.x+ and cannot be administrated via Admin plugin without any problems.

The last commit was pushed several years ago. Nonetheless, new issues and feature requests continue to be submitted.

Instead, consider using the Grav YouTube plugin. Sure, it only supports YouTube – but it's actually actively maintained and works on modern Grav installations without complaint. Forking that plugin to support alternate content delivery platforms (e.g., Vimeo, Imgur, LBRY) should also be feasible without too much hassle.

Folks, it's time to let sleeping plugins lie. :sleeping:
