Merry Christmas to all and a happy New Year Thanks for all the help so far.

Hi I solved the problem by uninstalling update December 10, 2019—KB4530684 (OS Builds 18362.535 and 18363.535) from Windows Update. Seams to solve the issue.

Thanks for all the help:)

Okay. I see nothing in the Windows Feature list that needs to be turned on. And, since things don't work in Vivaldi either, it's definitely your Windows 10 that's messed up.

Ok I understand that. But how can you explain it working on Opera about a week or two ago and now not? The system was installed about a year ago. (Tried system restore no results after restore everything refuses to even launch)

Is your Windows 10 locale English? If so, is it US English or UK English?

UK

Note that things work fine in Chrome because Chrome has built-in support for h.264 and doesn't rely on the OS.

If I didn't already suggest it, create a new user account on Windows, log into it and try in Opera there. When you're done testing, you can delete the user account.

Any difference?

Done It no change in behaviour.

Any security software installed? (like Bitdefender, Sandboxie, anti-virus, firewall besides the Windows one)

Nothing new

Installed K-Lite Codes Pack no effect

Unfortunately, those are DirectShow filters. They help for Windows Media Player, but they won't help for apps that use the Windows Media Foundation.

I got a notice I cant install it on my windows.!

Okay. And, I see from the pic, it doesn't show you have "N" or "Enterprise". That almost certainly means the issue is in your Windows 10. To test, test in Vivaldi. If things also don't work in it, then it's definitely your Windows 10.

Tested it. it Is not working.

In Windows 10, goto "start -> settings -> apps -> apps > features -> "options features". Make sure "Windows Media Player" is still installed. Also, click "add feature" and see if there's anything in the list that stands out (like something to do with media).

There was another user recently that had your exact problem. I'll see if I can find the thread.

Ok Thx

In Opera, goto the URL opera://settings/system, disable hardware acceleration and restart Opera. Does that fix it? (Do all the video tests again too.)

Tests done after diable

i see the issue the browser on the left is opera and on the right chrome.

@burnout426 said in Problems with Videos:

That explains a lot. You're lacking h.264 support in general, h.264 MSE support, and widevine support. That's definitely the cause of the issue.

Installed K-Lite Codes Pack no effect

This implies that you either have an enterprise version of Windows 10 Pro or an N version of Windows 10 Pro. If the latter, you need to install https://www.microsoft.com/en-us/software-download/mediafeaturepack for things to work in Opera.

I got a notice I cant install it on my windows.!

Another sign of that's the case is if Windows Media Play doesn't play h.264 files.

If you don't have an "N" or "Enterprise" version of Windows 10, I would think your Windows setup is broken.

Do a test to make sure it's not something with your Opera profile. Download the Opera installer, launch it, click "options", set "install path" to a folder named "Opera Test" on your desktop, set "install for" to "standalone installation", unchecked "Import data from default browser" and install. Test in that Opera, but do not install any extensions and do not enable Opera Sync.

Done it the Stand alone doesn't work as well

Also, in that Opera, goto the URL opera://components and update Widevine.

Widevine is up to date Version: 4.10.1582.2

If you can't get that Opera to work either, there's something that needs to be fixed on your setup of Windows 10.

But not so long ago everything was ok everything worked fine now it doesn't. Might You guess what can be the issue on win 10?

I am on: Your version is 65.0.3467.78 Opera

@nvmjustagirl

Chrome Works

@burnout426
Open up a private window in Opera and try playing the video there. Also, try disabling all the extensions you have installed in Opera (if any).

Done it nothing changed.

Do you have Opera's adblocker turned on? If so, try it with it off.

Its off still dosen't Work.

Do you have Opera's VPN turned on? If so, try it with it off.

Never Used it

Goto the URL opera://flags/#chromium-ua-compatibility, enable the flag and restart Opera.

Done it nothing changed.

What version of Windows are you on? Is it an "N" or "Enterprise" version? If "N", make sure you have the Windows Media Feature pack installed for Windows.

** Windows 10 PRO **
