Why doesn't anyone try opera-BETA 50 with chromium 63 ffmpeg codecs installed, since they are both built from the same sources? Instead, you all try workarounds to extract, move to the right place etc chromium 62 ffmpeg codecs to make it work with chromium-62-based opera stable.

Plus, if this really is the issue (the compatibility between the versions opera and chromium ffmpeg codecs are build), opera devs should move opera beta to stable faster. Chromium 63 reached stable at December 8th, so chromium-63-based opera beta should move to stable sooner.

Because 50's a beta, which I worry might be a worse option that adapting 49, especially if not technically able to fix other things. I didn't know about the beta, either. Opera should be getting the criticism, as they must know these issues will happen due to not releasing the right codecs at the same time. Just glad to know the option of keeping previous codecs, so things work.

Success......I hope!

Opened Synaptic Package Manager and removed chromium ffmpeg codecs extra 63.0.3239.84

Then downloaded and installed codecs-ffmpeg-extra_62.0.3202.94 as per http://launchpadlibrarian.net/345863538/chromium-codecs-ffmpeg-extra_62.0.3202.94-0ubuntu0.16.04.1317_amd64.deb

Restarted Opera 49.0 and videos are running again.

However Synaptic now shows this:

Oh and it seems the new Opera VPN that presently offers only 3 regions does slow videos down quite a bit when turned on. When VPN is turned off videos play very well.

Thanks so much for this. Running latest Opera version, Mint Cinnamon 18.1, and Youtube flash-html5 add on; with this, videos would play, set to html5, but not live videos. Now they work!

This is the reason for the odd numbering

Thanks for the link; good to know, although I still wish they just did a nice clear 1, 2, 3, etc, lol.

@jimunderscorep Thanks for confirmation, jimunderscorep, and for the code, as I've been able to see further recommended dependencies to check out. Yes, here's hoping Opera make sure all systems are covered, especially as major Linux OS upgrading isn't set to fully update for a few years yet, in Mint's case anyway. And people are running all kinds of older systems or previous releases, and having to now manually install things that just need to still be there isn't fun and may be beyond what many (new) users could handle.

Ok, but which one of the three is installed on your system? You can check it with

apt-cache policy libnss3

Packages.ubuntu.com reports that ubuntu has 3.28 as a security update for 14.04, 16.04 and 17.04 and 3.32 as th default one one for 17.10 and 18.04.. Assuming that mint 18.x is ubuntu 16.04 based, you should be having 3.28 as well...

Thanks jimunderscorep. Much appreciate.
With being worried about the browser being insecure, I hunted round for some deb files. Found those, and now the system reports what's below. I had not known the 3.26 version would be numbered 2.3.36 in synaptic, which I found out after installing the debs. At least it's resolved now, and thanks for responding.

I was using 18.1 just a couple of weeks ago, and have needed to return to it ... beyond me why Opera would suddenly upgrade so fast to something that doesn't look upgradeable in synaptic.

Concerned that system is insecure; will need to look for another browser if unable to update.

Hi, using Mint 18.1. Ran the Opera 49 deb file, but nothing happened. Typing 'opera' in terminal showed it needing NSS 3.26. I don't know what that is. Haven't been able to allow updates for Opera in Update Manager because of this; I let it go through once, but it still updated to the fatal error version. Luckily I had an Opera 47 deb file, which runs.

General faffing with different gif sites seems to have fixed it at this point, but it was 24 hours before there was an issue with the uploaded gif, so I'll see if it happens again.

Unfortunately, gif avatar has stopped working ... of 17 images within the 6kb 0-setting gif, only 3 now show, then it goes blank. It was working fine on day 1, but 24 hours later doesn't. I haven't done any updates/changes. Mint 18.3, latest version of Opera. Others say they can see it working fine on Firefox, so I don't know what's changed. I haven't changed anything. Have tried clearing cache, rebooting Opera and system, re-uploading the gif.
