Use YouTube poster for image thumb in Craft 5 CP element cards

[chrisrowe]

What would you like to see added to or changed in Embedded Assets, and why?

When choosing a YouTube embed the Craft 5 element card image shows the JSON file type, it'd be great if this plugin could instead use the poster (the image propery) from within this file?

This should be working already - is the image showing in the assets index? If so, could you please post an example of a YouTube video that's not showing the image on the card?

Aha thank you, yes it works for local filesystems but it seems that it's not working on a site staged on Servd https://servd.host/ their assets are stored offsite on an S3 compatible CDN.

Looking at _configureAssetThumbnails() it appears the $thumbnailUrl is correct and $event->url is being updated but the front end still shows the JSON file SVG, nothing of interest in the log files either. Any ideas or things to look out for?

I've run a test with an (admittedly different) S3 service and that's worked for me. I'll ask my colleagues if they've noticed any issues, but I have a couple of questions just to try to narrow down the cause:

• Do thumbnails work as expected for embedded asset types other than YouTube?
• Do they work as expected when using an assets field with a list or large thumbnail view mode?

Huh, has to be a Servd thing then, probably because files are publically avalible without a key which the Servd plugin handles when using getUrl. Here's a video with some more clues, (the dev volume is local) https://up.chri.sr/Screen-Recording-2024-11-18-11-39-08-1731929948.mp4.

Confirming thumbnails don't work with other view modes or in an asset field.

I poked around in your plugin code and was able to get the ytimg.com to output when debugging but I guess something else is going on
