Spectrum: YouTube URL not previewed/rendered

[pattacini]

It seems there's a glitch in Spectrum so that now when I copy & paste a YouTube URL within a post the corresponding video doesn't get embedded, at least in _Preview_.

The URL I was using is https://youtu.be/vmqL-YEnKGg, even though the glitch doesn't appear to be tied to a particular one.

This is because preview uses convert.spectrum.chat now, which only converts markdown to draftjs. Need to move the entire processing pipeline to it!

Thanks @mxstbr 👍
Does it mean that once posted the video is rendered correctly?

Just made an attempt on a private channel and it doesn't seem so.

[mxstbr]

It should definitely be rendered correctly, if not then that's a double bug! I will investigate tomorrow, thanks for the note :+1:

Hi @mxstbr

Any update on this?

[mxstbr]

Yes, I tried in production and it works perfectly fine after publishing. Here is what I wrote:

Here is what that rendered after publishing (not in the preview!):

Can you send me the exact input markdown you used? Also, is a browser extension potentially blocking YouTube embeds on your end?

[pattacini]

Thanks @mxstbr for being on this issue.

There wasn't any particular markdown I was fiddling with; I just tried multiple short combinations of text along with the link to make the video show up, but unsuccessfully.

I've also given a try to your specific testing post but it didn't work.

The weird thing is that I published this post recently in the same community and the video was embedded perfectly. Even more, if I copy & paste the text of that post in a new post, it works!

🤔 Can you send a screenshot?

[pattacini]

Of course! Here it is:

Further, I'm a Chrome user and thus with the idea to rule out any browser extension that might potentially interfere I tried out Edge and still the video didn't come off.

[pattacini]

Sorry to bother, but without rendered videos, most of our posts become somewhat "skinny". The eye catchy part is undoubtedly the video itself.

Thus, any news on this?

[mxstbr]

I managed to reproduce just now, very strange! Will dig into this today, sorry for the wait 👍

[pattacini]

It seems that now the video gets rendered correctly, even though preview doesn't work yet 👍

[mxstbr]

Great to hear, I fixed that in #4798, sorry for not making a note here! I will tackle the preview updates sometime soon, although they are a lot lower priority at the moment 👍

[pattacini]

Cool 👍
Thanks again.

Hi!

As a related request, could I ask that these embeds use the "privacy-enhanced" non-tracking API? It should be a fairly small/straightforward change to the embed code!

E.g.:

<iframe width="560" height="315"
 src="https://www.youtube-nocookie.com/embed/3RpKmuRX0CM"
 allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"
 frameborder="0" allowfullscreen>
</iframe>

[mxstbr]

Oh wow, is that an official thing? We should definitely switch to that if so!

[pattacini]

@mxstbr it's the signature you get from for example YouTube when you ask for the code to embed in your website in place of the mere URL.

[flaki]

Yes, it's in "beta" but it is indeed live on the Youtube share widget as a radio button as "privacy enhanced" embed.

Videos URL are broken again: see https://spectrum.chat/icub/news-debunked/whats-in-the-backstage-of-r1-at-the-hospital~14bb3cf2-5d30-4c76-9513-78fb02b357af for an example.

This time, also markdown links within posts are broken (see #5002) so that I was forced to put them explicitly.

[pattacini]

Uhm, what happened is:

• I dropped the link https://youtu.be/vmqL-YEnKGg in the post.
• The link was converted in its embeddable form and the video preview was correctly displayed.
• Then, I edited the post and saved but the video preview ceased to work.

Finally, by dropping the original link once more, I got it to work again.

[mxstbr]

Thanks for the reproduction, I have a pretty good idea what #5002 is about! Will fix tomorrow, sorry about the issues :pray:

@pattacini , @mxstbr Is this resolved? if not, I can take this up.

Cheers.

[pattacini]

@logeekal the URL is rendered correctly but not previewed yet.

[pattacini]

To add more info on this: when you also edit a post containing a video URL, the video is no longer rendered.

[logeekal]

Thanks.. will check it out.
