There appear 404 on some youtube thumbnails using maxresdefault

Please review, thanks!

Hey, thanks for the report.

Do you know of any documentation for the Youtube thumbnail service and why images may be missing? I do worry that it'll become a game of whack-a-mole if we switch to a different image format without some evidence that such a move will result in more resilience.

Hi I found this table https://stackoverflow.com/questions/2068344/how-do-i-get-a-youtube-video...

There are some thumbnails guaranteed to exist

I'm really hesitant to make blocking REST calls on the back-end. That opens up a lot of possibility for performance issues (what if the youtube API takes even 2-3 seconds to respond and there are 1000 web requests to a page per second?).

The guaranteed thumbnail dimensions are quite concerning...the max resolution is 480x360 -- that's definitely not going to work for some stakeholders. For example, the primary time (funding) for this module is Penn State World Campus -- who meticulously curates very high quality stills for any and all videos that we produce. I can't justify lowering quality across the board.

I think that the way I'd like to pursue solving this is to offer a couple of configurable options in the formatter settings that let site builders decide which images to use. That would offer folks a flexible workaround while not introducing any risk of Denial of Service vectors and also not degrading functionality for power users.

Setting back to NW for #6.

Hey Omar,

I invite you to check out the flexible-metadata-alter-architecture branch in the issue fork of https://www.drupal.org/project/oembed_lazyload/issues/3413985 ✨ Provide an extensible mechanism for thumbnail configuration and customization Needs work and see if it meets your needs. I've added support for more off-the-shelf rendering mechanisms while providing full backwards compatibility.

Let me know if this helps. I'm going to try to get #3413985 added to a 2.1.0 release in the coming weeks after tying up some loose ends.

Thanks

This behavior now has a solution and has been committed to 2.1.x, so marking as fixed.

Thanks!
