When I post a YouTube link, no thumbnail is generated with the post.

I see this issue on Codeberg as #269. It was created in 2024, and closed the same year. But was anything ever changed relating to video thumbnails in Piefed?

It works in Blorp 🙂

Can you give me a link to an example? And/or a screenshot?

You seem to be trying to insert a youtube video as an image.

It'd be good if, when a youtube link is on it's own (as below), it would turn into a clickable embedded video. But we don't have that functionality at the moment. Some 3rd party client apps might.

What's Blorp?

We've had similar issue some time ago, it was due to something in ngnix. I'll look around, maybe I have some notes about that somewhere

EDIT: pass these to your instance admins

Piefed/flask set it's own nonces so no need to add those in nginx

oh look my instance even has one. Thanks

Here's one I just posted in my community.

And here's a screenshot:

Ah I see, you have compact mode on.

I'll make a codeberg issue for that. Thanks!

Thanks Rimu!

It turns out the issue has something to do with Compact mode on Piefed. Rimu opened a Codeberg issue.

Turns out the issue is with compact mode. Whether I'm on Blorp or just default Piefed, thumbnails don't show up on compact mode.

But the good thing is that Remu has opened a Codeberg issue. So it'll be fixed sometime in the future. :)
