@[email protected] Heads up: this post's custom thumbnail does not display on Tesseract. It looks fine via the default Lemmy UI, even from an instance not on v0.19.5 yet.
Yeah, in Tesseract, a direct video link supersedes a thumbnail image.
Most of the time, there is no thumbnail image when a direct MP4 link is used, but I guess Catbox does seem to provide that when the metadata is fetched.
I'm on a development hiatus due to life chaos, but I think I can work that into the Click-to-Play behavior when I get back to working on it. Created a Github issue for that.
Just so it's clear: Lemmy 0.19.5 or so has an option for the user to manually provide a URL for a thumbnail image on a post that is separate/distinct from the main URL being posted. That is what I mean when I am referring to the "custom thumbnail". Note both the "URL" field and the separate "Thumbnail URL" field in this screenshot:
