It's working. There is no need to move any files

Thank you in-tensive. After a little hokey pokey I got this to work. Thank you for helping me learn a little more about Linux and how to fix this very annoying bug.

Not at all, kpsaver.
I am a fan of Opera Browser and happy to help you.
Despite some of the problems of our beloved web-browser ;)))))

Hi! Here is solution for Opera 43. (Kubuntu 16.04 x64)

1. We need to update Chromium browser to 56.0.2924.76 version (Opera 43 use this version of Chrome engine)
2. Add repository - sudo add-apt-repository ppa:canonical-chromium-builds/stage
3. Update system - sudo apt update
4. Chromium must updated to 56 version
5. As recently as advised tyrion-ua:
   Copy the libffmpeg.so file from the library (/usr/lib/chromium-browser)
   Replace the libffmpeg.so file in the browser folder (/usr/lib/x86_64-linux-gnu/opera) with this file.
   Restart the browser.
   Now Opera plays videos from Twitter, Instagram, etc.

But finally got it working. For Opera 43.0.2442.806 on Ubuntu Xenial 16.04 I had to:

• Download the package opera-ffmpeg-codecs-56.0.2924.76-1-x86_64.pkg.tar.xz from https://repo.herecura.eu/herecura/x86_64
• Extract the libffmpeg.so file
• Then move it to /usr/lib/x86_64-linux-gnu/opera/libffmpeg.so. Had to use "sudo"

Do NOT put it inside "/usr/lib/x86_64-linux-gnu/opera/lib_extra".

Seriously, I don't know why tf the directory changed again in this release or why Opera for Linux has to be so f* complicated.

No.

But be safe and backup "/home/rudi/.config/opera"(replace rudi with your directory) then in the event of a mishap simply replace that directory with your backup.

Was trying to download from the above suggested sites and having problems downloading and installing deb packages.

Anyhoo, for some reason I decided to clean out the Downloads folder and lo and behold there was the

'opera-stable_42.0.2393.517_amd64.deb' package from when I originally installed Opera.

So after uninstalling Opera 43 and reinstalling 'opera-stable_42.0.2393.517_amd64.deb' everything works, nothing else required.

I like to apologize to jgffopera for taking over his post but hopefully it has helped him. I will be book marking this post for future reference that's for sure.

Thank you all.

Right ON !!
Thanks

It was your idea. I just modified it.

What is not understood is that being an excellent browser, probably the best of the day, this error in playing videos on Facebook, Twitter, and Tumblr, often comes up giving the idea that even a seeming mistake.

It's easy to fix it by reverting back to Opera 42 and ffmpeg 53. I basically downloaded Opera from Tyrion and then used my older guide from here:

https://forums.opera.com/topic/18564/incompatibility-with-the-latest-chromium-codecs-ffmpeg-extra-in-ubuntu

Everything works.

• Remove new Opera
• Download deb package from here: https://yadi.sk/d/KDMMF4R83DWEuq (it's my cloud) or https://get.geo.opera.com/pub/opera/desktop/
• Install Opera version 42.0.2393.94
• Download libffmpeg.so from my cloud
• Put it into /usr/lib/x86_64-linux-gnu/opera and replace (need root).

Sorry, but i'm not tested "i386" version, but "amd64" works great.

• Install the chromium-codecs-ffmpeg-extra library.
• Copy the libffmpeg.so file from the library (/usr/lib/chromium-browser)
• Replace the libffmpeg.so file in the browser folder (/usr/lib/x86_64-linux-gnu/opera) with this file.
• Restart the browser.

But in the new version (43.0.2442.806) it no longer works.

In this topic (http://forum.ubuntu.ru/index.php?topic=266804.0) written (forum in russian language): version of the file libffmpeg.so must be the same version of the engine chromium used browser Opera. In Opera 42.0.2393.94 chromium engine, I guess, 56.0.2924.76. But i can't find the chromium-codecs-ffmpeg the same version.

At page https://www.youtube.com/html5 seen that the problem is the H.264 codec:

Youtube supports
• MP4 (a multimedia container format standard specified as a part of MPEG-4)
• FLV (Flash Video, a kind of video format )
• AVI (Audio Video Interleaved,a kind of video format)
• MOV (the QuickTime multimedia file format)
• 3GP (a multimedia container format defined by the Third Generation Partnership Project for 3G UMTS multimedia services.)
• MKV (an free container format that holds an unlimited number of video, audio, picture, or subtitle tracks in one file)
• MPEG (the Moving Picture Experts Group, a kind of video format)
• WMV (Windows Media Video)
• SWF (Shockwave Flash)

I have NO problems with Youtube.

As I said, all was good on Opera 42, I would love to downgrade to it, but cannot find a download for it.
