@leocg Sorry, I didn't see any error message. Could you be more explicit?

Just performed the latest update (Opera One: 128.0.5807.77 / Chromium: 144.0.7559.173). The problem persist (the adblocker is still broken), but with no error message.

@misterrr Just checked again.

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

That same message appears when I open the page on Chrome.

@leocg I said in the first message:

• with adblocker on: instead of video I get a black frame with no video:

• with adblocker off: I get no error, the video plays but with unwanted behaviour.

I tested now with Opera 127.0.5778.76 and it works ok, as expected (as before update to 128).

So, definitely Opera 128 is broken and should be withdrawn until solved.

@leocg I would like to mention that I tested also in Chrome, Edge and Firefox. Video loads ok, with no error.

@misterrr My DNS provider blocks ads, among other things, maybe that is causing issues when loading the videos

@leocg That doesn't explain why Opera 128 is not workinkg anymore and Opera 127 works without issues.
I didn't changed the DNS provider. Only updated Opera from 127 to 128.
Did you tested with Opera 127?

@leocg Also, if DNS blocking were active, videos would be blocked regardless of Opera adblocker enabled or disabled.

Not having any issues with videos playing on the site with or without Opera's adblocker in Opera 128.0.5807.77 on Windows 11 23H2 for what it's worth.

@misterrr I'm glad the issue doesn't exist in version 127.

The problematic version 128 was available only for a few days. We can't simply force users to roll back by having them reinstall it.
If you download Opera today, it will be version 127.

Thanks to everyone for all the details and for investigating together

@burnout426 Yes, but I think that in order to be able to play the videos with adblocker on, you have to add the site to exceptions. In Opera 127 that was not necessary.

@Mlipka Ok. I hope that in the next Opera update the problem will be solved. I will keep you informed.

Thank you all!

@misterrr I didn't have to in 128.0.5807.77 for what it's worth.

@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...
