I'd be surprised if that test worked on any platform in existence. You're using the markdown to render a static image, and sticking a youtube URL in there. PieFed supports it if the URL ends in something like .mp4, but that's only because Lemmy have fudged it, and so now people expect it. There's meant to be a 1:1 relationship between markdown and HTML, metadata transformed into metadata - nothing should have to look at the actual contents to know what tags to produce.

As for 'works for me embedded in mbin' ... eh? It looks like this in mbin:

That's literally just a external link to youtube. It 'works' because it doesn't - same as for the screenshot itself - instead of embedding it, it just coughs up the link to a remote site. Everything else is rendering it as it is - a broken link to an image that doesn't exist.

(maybe 'originallucifer' has some fancy app that takes a youtube shorts URL, works out the embed code, and then puts it in an iframe ... but like I say, I'd be surprised).

(1) it works in Mbin though. I would expect it to work also in Tesseract, though the comment string still has not federated yet - perhaps the user is blocked for some reason, or all these numerous federation issues by most non-LW instances have prevented it.

Yes admittedly the Mbin embed is a bit strange, that looks vaguely somewhat like the "broken link" icon that shows up in Lemmy or PieFed, but it's actually not - that double-window looking icon is a signal for content that you can play directly inside of Mbin without having to leave it to go to a 3rd-party site. So click it, and it will bring up the entire YouTube video right there in-line.

That double-icon is also accessible while still browsing posts, so really you don't even have to go inside the full post in order to see it, e.g. you can see the double-window icon somewhat to the bottom left (though to the right of the preview area) of the page at fedia.io/search?q=Silent+Hill+… just to the left of "Comments Boost More", down below the username "chloyster". Clicking it expands the preview just below the listing of the post.

(2) Here is a positive example where a YouTube embed works on PieFed. Based on my test here, it does not seem to work in comments, but it does for posts?

And here is another one that works on dubvee.org: dubvee.org/post/dubvee.org/187…

Due to federation weirdness, the former post is not available on dubvee.org, and the latter one is not available on piefed, but anyway you can see that individually, those two platforms both are able to embed YouTube videos. At least, for posts, again not comments.

I believe this post describes when it was added to Tesseract, so somewhat recently (one month).

And Mbin works too - you have to click the double-window icon to get it to show, but when you do, it reveals the preview and you can play the YouTube video right there without having to leave the site. Here is the former example, and here is the latter example.

These features may have to go through extra hoops as you are saying, yet they "just work" so that the user can enjoy that extra functionality without having to sweat the details.😀

Ah, I see now, thanks. That makes more sense than my previous theory, that MBIN users were pathological liars or something. Also, now my previous comment makes me look like an idiot. Oh, well.

It's interesting what MBIN does - making the user click a button gives it an extra chance to query the remote site, so it can render it correctly. That's not the same as taking the markdown and rendering it as HTML, but the end result is nice.

Elsewhere (like on PieFed), Youtube embedding works well because the URL is in a nice dedicated field, so it's easy to process, rather than parse through the text of a comment to find it. No idea what's happening with Tesseract, but it's just a front-end for Lemmy (albeit a sophisticated one), so my guess is that your link would fail, but since the comments aren't there, it's a bit moot.

Haha I think it is fully proper to ask every valid question like this - and in particular, like we see happen with PieFed all the time, and also Tesseract, someone could legitimately modify their particular instance in unusual ways that aren't committed to the common codebase yet (awaiting review, or potentially confusing, or cause trouble integrating with new upcoming features also trying to be committed?😀.

And I wasn't sure if my answer was appropriate or not - like if you saw it and knew already but you meant something totally different but then I completely missed, so thank you for your honesty bc it does make me feel better that I wasn't being a complete dolt here.

As for missing that feature... hehe I did as well, and this despite my first experiences with the Fediverse having been Kbin for MONTHS until it imploded:-(. It really does look very much like a broken image icon, and that's just a poor design decision on the part of Kbin's creator, imho. That said it's quite a useful feature, and I used it quite often - many times per day and even per hour. And still forgot all about it!?!?!😛 (it just looks that much like the broken image icon!!!! we don't even question it, OF COURSE that's what it is - what else could it possibly be‼️⁉️)

So yeah, thanks for your bravery (in like not merely deleting your prior comment, or you probably really could have brow-beat me into submission here with technical jargon) - it only makes me respect you more you know. As for others who choose to feel the opposite, that's on them:-D.
