After update, the promo says:

What’s new in Opera

Now watching videos in Opera is a whole lot better.
Video Popout
Detach online videos into their own adjustable, movable, floating window. YouTube, Netflix, Twitch, football streaming sites - almost any video provider.
With Opera, start a YouTube video or any supported online video, and a new button will appear at the top center. Click it to open the video in a smaller popout window.
The button appears in the top-center when you mouse over an online video.
You can resize this floating window and place it anywhere on your screen.
You can move it wherever you want, as well as adjust the size.
The popout window has its own controls, letting you pause, close it with one click, or return it to the original tab.

Unfortunately, there is nothing "a whole lot" better. Or even true:

• the main video in page has no such button at the top center for detach the video (when mouse over the video)
• the video popout opens by himself despite the fact that this feature is disabled in Opera settings
• the video popout appears in the lower right corner of the page and it cannot be moved or resized
• the video popout has no controls to return it to the original tab

So, I think that it is a lot of work to do to make this promo to be real.

Just updated to the new version:

Versiune Opera One: 130.0.5847.41
Versiune Chromium: 146.0.7680.178

Nothing changed. The problem is still here.

I created a bug report about that, as you suggested:
BUG-23740

The only result is that I got an automated answer, which unfortunately has nothing to do with the problem.

Any help?

I did some further investigation into my settings in the adblocker / exceptions / lists area because I think that's where the problem is:

I found something that makes a small difference if I remove it. It's a list I added in 2024 but I haven't had any problems with it so far:

If I remove this list, the videos load when the page loads (the video frame is no longer black without the video) and can be started, but the other problems (which I think are related to Opera's behavior) remain:

• when the page loads, the videos start by themselves, without me giving the "play" command
• when the page loads, the videos are on "mute" and must be put on "unmute"
• when scrolling down the page, when the video clip goes off screen, a pop-up appears with the clip in the lower right corner of the page, without me asking for this
• when scrolling down the page, when the video clip goes off screen, a pop-up appears with the clip in the lower right corner of the page, which restarts even if the clip in its main frame was stopped, without me asking for this

I mention that all the settings for detached video and for Video Popout | Picture-in-picture video are disabled, but Opera does not apply these settings:

These are unwanted behaviors that should not exist.

I would like the videos to be stopped on page load (and not start on their own even if I scroll the page) and to be unmuted. Now it is the opposite.

Just updated to the new version:

From:
Versiune Opera One: 129.0.5823.15
Versiune Chromium: 145.0.7632.117

To:
Versiune Opera One: 129.0.5823.28
Versiune Chromium: 145.0.7632.117

Unfortunately nothing changed. The problem is still here: black screen instead of video (with adblocker enabled) and unwanted behaviour (with adblocker enabled and site added to exceptions).

I don't understand why non-working versions are published, instead of maintaining in place the last 127 working version, until the problems will be solved.

@Mlipka No, it's not enabled:

@Mlipka No, I don't have any other AdBlocker (excepting Opera AdBlocker).

Example for https://stirileprotv.ro/stiri/doctor-de-bine/combinatiile-de-alimente-care-iti-potenteaza-nutrientii-si-aduc-beneficii-mai-mari-decat-suplimentele-alimentare.html

Console with adblocker on and no exceptions added (video does not load):

Console with adblocker on and website added to exceptions (video is loaded):

I see that I can't attach har file (for network) or console log file.

@Mlipka Just updated to the new version:

From:
Versiune Opera One: 128.0.5807.77
Versiune Chromium: 144.0.7559.173

To:
Versiune Opera One: 129.0.5823.15
Versiune Chromium: 145.0.7632.117

Unfortunately nothing changed. The problem is still here: black screen instead of video (with adblocker enabled) and unwanted behaviour (with adblocker enabled and site added to exceptions).

I think this 129 version should also be withdrawn as soon as possible to avoid spreading and replaced with 127 working version., until the problems will be solved.

@Mlipka In order to avoid a fresh install, and to update automatically to all users, it would be possible to publish an update that in fact is the last working version (127), obviously with a version number greater than the current non-working version?

@burnout426 So, to summarize, until now we have three behaviours in Opera 128:

• @leocg: with ad blocker on: video doesn't even show, its space is blank. With ad blocker off, I got a Media Element Error: Format Error message
• @burnout426: video ok / no error
• @misterrr: with adblocker on (and no site added to exceptions): instead of video I get a black frame with no video / with adblocker off (or site added to exceptions): I get no error, the video plays but with unwanted behaviour

Strange...
