[Bug]: youtube embeds (for non-yt feeds) giving error 153 despite 7e2dd3af

[Ivan8or]

Bug Summary

Embedded youtube videos (from non-youtube rss with 'fetch original content' enabled) fail to load; embed shows as "Error 153".

Description

youtube embeds from non-youtube sites are failing to load, with "Error 153".

#3862 seems to have fixed the error when pulling from youtube's RSS feeds, however I am still seeing the error for non-youtube articles that have an embedded video.

Steps to Reproduce

1. create a new Feed using an RSS feed which has an article with an embedded youtube video (I am using https://hnrss.org/newest?points=1000) - enable Fetch Original Content
2. open an article with an embedded youtube video (I chose Android developer verification: Early access starts)
3. note that the embedded video failed to load, with Error 153

Expected Behavior

The video should embed properly, rather than failing to load. The iframe should have the referrer policy mentioned in #3862

Actual Behavior

The video fails to embed.
The HTML for the embed portion looks like this:

<iframe allowfullscreen="" height="413" src="https://www.youtube-nocookie.com/embed/jEATR5sF5Lo" width="100%" sandbox="allow-scripts allow-same-origin allow-popups allow-popups-to-escape-sandbox" loading="lazy"></iframe>

Browser

[Ivan8or]

@Subbacultcha fguillot pushed a fix 7e2dd3a in response to your previous issue, however his fix did not address youtube embeds for feeds that fetch original page content, that is why i made this second issue

[guest20]

I also see #3868 - Error 153: Video player configuration error from youtube videos on youtube feeds on 2.2.14 + FF 145.0.1 (64-bit windows).

Is #3862 in a tagged release?

[fguillot]

PR #3902 should fix the issue for both YouTube feeds and YouTube embed videos. It's not yet available in a tagged release, but you can use the nightly version for testing purpose.

@fguillot

• :nightly did the trick!
• Thank you for making very good software.
• Also, should this fix apply to items fetched before I switched to :nightly?
