<![CDATA[Opera 50 not supporting H.264 videos anymore?]]>Hello everybody,

I recently reinstalled windows and did a fresh install of opera. Everything seemed to work ok until the last couple of updates. Youtube is telling me that my browser doesn't support HTML5 video. When I click on info I'm presented with this same screen:
alt text

I've just updated to the latest version and still getting the same error. From the about section:
Version information
Version: 50.0.2762.45 (PGO) - Opera is up to date
Update stream: Stable
System: Windows 10 64-bit

This is a recent problem that has slowly gotten worse with each update. Now any video is unplayable. I also have opera running on MacOS and that one doesn't have any issues. This seems to be a windows version problem.

EDIT: Rebooted into linux, am getting the same error message on linux on the same video. About page for linux here:
Version information

Version: 49.0.2725.39 - New version 50.0.2762.45 is available
Update stream: Stable
System: Solus 3 (x86_64; Budgie:GNOME)

EDIT2: It seems under linux that regular videos work, only live streams don't work. For example this gives me the error message: https://www.youtube.com/watch?v=2uA0rXgC4H4

Happens to me all the time (after upgrade) in openSUSE Leap. I don't know exact solution now, but could post it in a day or two after I get back home. On Xubuntu works without these issues. AMD opensource radeon drivers in both cases

Also, does https://html5test.com/ list H264 as being supported?

What opera://gpu says about video decode?

In my case I don't have FlashPlayer installed, instead I use a portable Flash version and it's just "switch" pointed to an Entertainment profile as well to a Test profiles, despite that, Youtube works fine on any of my non Flash enabled profiles.

In case you are interested in give another chance, here is the link.

I installed 48, copied the profile files over, still doesn't work. At least I know it's a flash issue. I tested to see if flash gets detected and it says it isn't installed or running. I'm fine with that as I don't want it on my system anyway, but why aren't html5 videos working though? As far as I am aware HTML5 and flash are 2 different beasts.

I think we can just finish this debugging session, I'll just wait a few more weeks for another update where this might get fixed eventually. Considering I'm getting this error on different OSs as well with the same Opera version I don't think it's something I need to install extra for the browser.

Thanks for the help.

On the WiDevine link, then on the O48 link, - it's from the Opera's FTP -.

I get to the page where I'm to download a 36.6mb file, but when I click download it downloads the 1.2mb online installer. So from here?:
https://www.opera.com/download/index.dml/?os=windows&ver=48.0.2685.52&local=y

Then try the above steps, installing Opera 48 but:

  • Download O48 offline installer
  • Use the options to do a Standalone installation
  • Disable network connection
  • Rename O48 auto-update file
  • Connect to internet
  • Test Youtube

Mine had 2 files in platform_speciffic, but none of the rest. Even after deleting the old files stil not working with the ones from the zip. I don't think this is a windows specific problem anymore, because it should be working on linux just the same, but it's not.

I have no problem on W10 and 2 laptops.

Try to copy/paste WiDevine folder on Opera's install folder - if empty -.

With firefox I was directed to this hotfix:
https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows?as=u&utm_source=inproduct
This didn't work, even after restart.

Finally installed chrome and that seems to be working. I honestly don't know what the issue is. On linux for example firefox is working, but vivaldi that is another chromium based browser isn't. Is this maybe a hardware issue because of the big bug they found the couple of days ago?

So for now I wasn't able to find a solution, still trying things out. I honestly don't want to use chrome because it's lacking so much stuff. I sure hope this gets fixed soon. I'll be waiting patiently.

You may have to look at How to report problems in Opera steps.

For the clean profile:

  • Opera Help > Find solutions.
    | - And rename the profile folder -.

Or use the signature's "Test profile" option.

Windows 10 (x64) | Anniversary Update
Opera Stable · Beta · Developer

Opera Test profile | Opera Back up Linux · Mac · Win
