I installed the media entity module, the video embed field module and also the entity embed module.
Then I created a media bundle for videos. Created a embed entity button for media and added it to CKEditor
I created a new video bundle entity with a link to a youtube video. When I visit the entity I see the embedded YouTube player and I can play the video.
So far so good. Now I like to embed this media entity into another entity (Content type "Article"). I can do this over the CKEditor button created before and I can also select the video media entity.
What's not possible is to render the entity as an actual video. The only options are Label, Entity ID and Thumbnail. But a Video formatter is missing.
Probably I miss something? A well hidden option to (un)check or even a module to achieve this?
