This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
What does it do?¶
This extension provides a new content type “External media”. The editor only needs to provide the URL to the media he wants to embed.
The media will then be embedded via an oEmbed request if a matching provider was found. For more information on oEmbed see: https://oembed.com
Additionally the extension gives administrators the possibility to manage oEmbed providers. It comes with a number of default providers out of the box.
