YouTube Embedded Videos Not Displaying on My Site


Description of the issue:
if I open this page https://www.delladio.it/un-dibattito-fazioso-e-un-eccellente-professore.html I don’t see the videos after the end-of-page break bar but only the description line. If I exclude the protection the videos miraculously appear. In some cases, if I edit the article, delete the blocks and insert them again, the problem seems to be solved. With Peertube no problem

Exact URL of the website in question:

Did the issue present with default Shields settings? (yes/no)
Yes

Does the site function as expected when Shields are turned off?
Yes

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
No. the configuration is the default one during installation

Does the site work as expected when using Chrome?
Yes

Brave version (check About Brave):
1.69.168

@maudel,
The page you linked to does not appear to exist. Even in Chrome and Firefox, that link only shows (image is in Chrome):

However, I did find this page: https://www.delladio.it/big-data-cosa-sono-e-cosa-sanno-di-noi.html

On that page, there is an embedded Youtube video that displays and plays as expected in Brave:

Can you tell me if the embedded video appears in the other link I sent when viewing the site in Brave?

I corrected the link https://www.delladio.it/un-dibattito-fazioso-e-un-eccellente-professore.html and now it points to the page correctly but the problem remains
The other link https://www.delladio.it/big-data-cosa-sono-e-cosa-sanno-di-noi.html seems to have started working again after I removed and re-inserted the video several times.

Hello. Is there anyone who can suggest a solution to this problem? No extensions have been installed that could cause conflicts and the protection configuration is the default one. Another oddity is that if you disable the protection and then re-enable it, sometimes the page is displayed correctly. An obvious bug that I have reported several times. It would probably be necessary to set up specific filters that I do not have the skills to indicate.

@maudel,
On my end, I do not see any video content on the pages you linked above with Brave’s Shields on or off. Further, no video is displayed when viewing these pages in Chrome or Firefox. Also, when inspecting the page, I do not see any embedded video elements listed.

If you’re certain that you’ve shared the correct links above, then I’m inclined to think that the issue is on the site itself, rather than an issue with Brave.

You are right, those links were wrong. Can you try opening this page

with Brave and Chrome? If opened with Brave, at the bottom of the page, only two bars with the description appear. With other browsers, two videos appear. I am not used to representing non-existent problems. This site has been around for years and opens quickly and correctly with any browser.

I’m doing some tests. Maybe the problem could be related to the compatibility of a plugin inside Jetpack for inserting YouTube videos. Normally the plugin allows inserting and/or embedding a video but in the attempts I’m making it only allows for incorporation which doesn’t work. Using the external plugin “Video Embed (ARVE)” instead the problem doesn’t seem to arise

While I do see where the videos should be on that page, they still don’t appear in Brave or in Chrome. Here’s what I see in Chrome next to what I see in Brave:

Note that if I disable Brave’s Shields, it will display the same way it does in Chrome.

In the meantime, I can only thank you for your availability and patience. I believe, as I said, that the problem is generated by Jetpack’s YouTube video insertion module because the problem occurs only when using that module. But what Chrome returns to me integrates the videos (in the screenshot not clearly represented but visible and present) while Brave does not consider their presence at all.
The link I am referring to is the following:

It is clear that in the Brave screen, configured with its default protections, instead of displaying the videos, you see two page break bars (if there is a description, the description itself), in the case of Chrome or Firefox the videos themselves appear instead. It is clear that, if I disable the protections, the problem does not arise. However, I believe that this choice is not consistent with the philosophy of Brave. Of course, if there is no other solution, I will adopt the choice of deactivation.

both the embedded YT and vimeo videos work here. Does it work in private window mode?

As you yourself have seen, videos inserted in an article are not visible either as thumbnails or as videos. The video in the article should be between the two page break bars that you see. Even with an anonymous window the situation does not change. Everything works instead if you disable Brave protection or if you use Chrome or another browser.
Strangely enough, videos inserted in the sidebar are visible but not those inserted/embedded in articles. Also, the problem occurs with YouTube and not with Peertube.

Hi,

I have looked into the matter further and, in addition to the DevTools errors I found, I am also attaching other details.

Analyzing the html elements shown by Chrome and Brave and comparing them, I noticed this difference that I believe is relevant.

Here is the element relating to the video as it is shown on Chrome, where the video is visible

<iframe src="https://www.youtube.com/embed/xLqSzlb_Z1k?feature=oembed" title="Baustelle - Contro il mondo (Official Video)" width="1440" height="810" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" class="_iub_cs_activate _iub_cs_activate-activated" data-iub-purposes="3" async="false"></iframe>

while on Brave the element appears like this

<iframe title="Baustelle - Contro il mondo (Official Video)" width="1440" height="810" src="//cdn.iubenda.com/cookie_solution/empty.html" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="" suppressedsrc="https://www.youtube.com/embed/xLqSzlb_Z1k?feature=oembed" class=" _iub_cs_activate" data-iub-purposes="3"></iframe>

I think there is some kind of cookie which is been blocked by Brave, resulting in this “suppressedsrc” attribute present in the second html element, maybe activated by Iubenda policy. Is it possible?

By the way, here it is the other informations from the DevTools Network and Console sections:

I am sending this email to both JetPack engineers and the Brave forum.

Waiting for your reply,

Thanks and greetings
