This is a bit weird, why are we loading the iframe of the embed extraction the src ... Can't we just render the iframe directly (like we do in the frontend I guess)

I guess we should check how the embed preview works in the embed block and do the same.

Looking at the Embed block looks the logic is a bit involved and implemented in EmbedPreview. I wonder if we should have a similar logic using the Sandbox component.

Alternatively, maybe all this processing can happen in EmbedVideoUrlInput or in the submit callback.
The embed block has to do it during rendering as a side effect, because it deals with embeddable URLs and converts them into iframes, which mimics how WordPress handles this on the front end.

Loving it so far! The default overlay opacity is 100, making it impossible to see the video if you don't know how to adjust it. |

Once the video is added, replacing it with a new one becomes difficult because the video URL field stays empty. The user can swap a video for another by first resetting the cover block. |

I like that this logic is contained now, I think probably we could also guess the embedProvider from the html like we do in frontend to avoid the extra attribute.

Looks like YouTube is broken on the editor but works on the frontend. |

Do we need to add an option to the placeholder? |

Is this classname needed or should we clearly separate the "embed" from the "video" background rendering/classes?

This is looking good to me in terms of flow / code / behavior. I don't know if we could fix the YouTube preview in the editor. Other than that I left small comments but no big things.

I thought it was a bit much, so we could start by adding the support in the dropdown only. |

Ok I tested this on playground and it works great. Youtube has issues when it comes to localhost. |

I think this is working great for me. IT would have been great if oembed's supported the "no buttons" approach more easily but the code is contained and can be improved later.

Any chance we can add a filter to support programmatically disabling this feature? We surely do not want any content provider in our MultiSite instance to use this feature 🤞 |

@MadtownLems is that specifically for the cover block use or do you also disable the corresponding embed use? |
We support standard YouTube embeds, and are trying to disable video behind cover blocks. There are several related threads, many of which you are also in. :) I think #75069 (comment) covers 'why' pretty well. |
