embedded Youtube videos are broken.

Thanks for the Info.
I have enabled ghosterys advanced anti-tracking again.
Enabling flash didn't do the trick, but changing the user agent string from

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.189 Safari/537.36 Vivaldi/1.95.1077.55

to

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Safari/537.36

did it!

//EDIT:
hmm... now some other websites look weird. I'll try out some other user agent strings.
Great tipp! thanks again

//EDIT:
using
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36
now. Works perfekt! ...maybe just placebo, but I feel even faster loading times now.

I am using Ghostery too. And will never disable it. +Advanced anti-tracking with 0 exceptions.

I am glad you did it. Sometimes, if a certain embedded flash returns the same error, just try to allow Flash for this site.

I am glad you did it, man

Cheers!

JFYI Please, do some restarts (I mean Vivaldi), and if you have in your Windows something like Disk Utility like I have in Mac OS X, do the necessary to purge the temporary data. You may also want to reinitialize the Flash data (System Preferences on Mac Control Panel in Windows).

@gwen-dragon Nevertheless, what I describe is working (see the screenshots in 1st post). One and same website opened in Safari and than in Vivaldi showed me what Freeman79 has reported. Both browsers I am using were using identical extensions (including ghostery).
Even today Safari is capable to play much more medias than Vivaldi. Its non relevant user-agent and the chromium internal remains are the main problem. I am using Vivaldi from 2015 and I know what I am speaking.
The fact that one website is using a HTML5 player does not guarantee that it will run at 100% in Vivaldi. Which is not the case of Safari. (Plus the ad blocking & alias extensions users always install).

@gwen-dragon
It's true, flash isn't needed but anyway that hint from @zmeYpc was a diamond one!
Changing the user-agent fixed a lot of stuff for me now, not only the embedded videos but also MUCH less dropped frames and less stuttering 60FPS Streams on twitch. I was even able to watch a very long stream without a dead bird, yesterday. And those dead birds happend for me all the time since I started using vivaldi.

It may be related to an issue with 3rd party content embedded in an iframe and not just video.

Here is a site where iframe embedded youtube vids don't play:

Both links are working for me with that changed user agent

@freeman79 Thanks, but that didn't work.

I did however finally solve the problem and it was (of course) self-inflicted. I had enabled 'strict site isolation' in vivaldi://flags in a fit of paranoia and forgot about it. There is a warning at the top of the flags page that warns that the experiments there can 'bite' and I got bit.

So in the immortal words of Rosanne Rosannadanna, "Never mind!"

I forgot to reply to you (before Freeman79 did it) here, that I also checked your links, and:

PS I’d suggest you to install some user-agent ext, and see yourself (how sites welcome Vivaldi).

@gwen-dragon I also had this problem it latest Snapshots, so I moved to stable release channel. From my observation, it has nothing to do with profile or extensions. The same problem was while using private mode. But I enabled "Strict site isolation (#enable-site-per-process)" deliberately to strengthen security due to Meltdown and Spectre, as it is one of suggested step on many security sites for Chromium based browsers. And yet, there's no problem with playing of iframe videos with this option enabled on Chromium releases.

stealth789

Is there any plan to fix this issue? To be able to have secure browser and at the same time to be able to play iframe videos/content?

@stealth789 Chromium is in the process of fixing it.
