@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...

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

Thank you all!

@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.

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

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

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So, definitely Opera 128 is broken and should be withdrawn until solved.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

@Mlipka Ok, thanks!
I hope to hear from you soon.
