UPDATE: As been demonstrated in a new thread, Flash video problems never end, the first option might not resolve the case anymore. However, a new solution was suggested by @natasha-from-dnepropetrovsk

 DOWNLOAD:  https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/download/0.20.3/0.20.3-linux-x64.zip
 EXTRACT:   "0.20.3/0.20.3-linux-x64.zip" as "libffmpeg.so"
 RENAME:    "/usr/x86_64-linux-gnu/opera/libffmpeg.so" to "/usr/x86_64-linux-gnu/opera/libffmpeg.so_orig"
 COPY:      "~/Downloads/libffmpeg.so" to "/usr/x86_64-linux-gnu/opera/"

According to my calculations, this is now the eighteenth case concerning Flash problems when it comes to the Opera browser. I have Chromium as my backup browser, and I can tell you, no such problem has ever been encountered!

Here are the three most recent cases after the fifteen, when this thread was originally composed: (16) Flash video problems never end, (17) New user Debian - Flash - Licence - Devices - Report, and (18) Flash player not work in Last opera stable and developer

@perknh, unfortunately the problem has re-emerged. "opera://plugins" gives the version information as folllows:

Adobe Flash Player
Version: 21.0.0.216
Shockwave Flash 21.0 r0

However, when I try to open media that requires flash, I'm told that "Adobe Flash Player is out of date." I have no problems running Flash with my Chromium browser though, so it's just Opera.

Hi there @perknh! Just like many movies have an interesting plot line, but the climax can be kind of a boring one, so it is with our journey:

Upgrading to Linux Ubuntu 16.04 LTS fixed all the problems. Now, both my Opera and Chromium are running the latest version of flash. This doesn't mean, of course, that installing the pepperflash-plugin wouldn't be necessary. Well, Firefox is long purged now, and now I have moved exclusively to Opera.

Well, I expect this thread still can be found useful for those Linux users who are still waiting for the Linux Ubuntu 16.04.1 LTS release (indeed, at this point I am still running a test-version).

Thanks all of you guys, especially @perknh! The Linux community has proved worthy of its reputation as a source of technical support! This is something I've never experienced in the Windows camp. Thank you!

@perknh: Sorry for keeping you waiting, my friend! It's been a busy day for sure! I must say, now finally it is starting to make sense to me Let's see...

1. The version of Opera that I am currently running is reported as follows:

   Version: 37.0.2178.32 - Opera is up to date
   Update stream: Stable
   System: Ubuntu 14.04.4 LTS (x86_64; Unity)

2. Yes, I did reboot and check if it is working, but it is not Also tested by some flash-requiring applications that my Chromium can run, but Firefox and Opera cannot.

Here is my own analysis:

3. "adobeflash-plugin" indeed does prevent "pepperflash-plugin" from working properly. Whereas the former is installed, the system automatically prefers it over the latter one. Could this problem be overcome? Perhaps. For example, if you see the "Install Pepper Flash for Chromium in Ubuntu" instructions (www.webupd8.org/2013/04/install-pepper-flash-player-for.html), their attempt is to create a gedit file for the browser to use pepperflash as its default settings. Maybe this could be used for the Opera browser as well. However, that didn't work in my case with my Chromium.

4. Now, let's have a quick chronological overview:

   First, the only browser I had was Firefox
   Second, I installed the Chromium browser to my Linux Ubuntu 14.04 LTS system
   Third, @perknh helped me to install pepperflash-plugin here at the Opera forum; this included purging all the remains of "adobeflash-plugin"
   Fifth, the "pepperflash-plugin" started to work perfectly on my Chromium
   Sixth, I installed the Opera browser; MY ASSUMPTION is that the Opera browser comes with "adobeflash-plugin" that does prevent "pepperflash-plugin" from working properly (which takes us back to square ONE)
   Seventh, as said in the sixth step indeed, the "pepperflash-plugin" in my Chromium DID STOP from working. HOWEVER, Opera now displays this bugged flash version "99.xxxxxxxxxx" etc.
   Eight [after a lot of hassle...], I finally re-purged the "adobeflash-plugin". The result is two-fold: 1) Opera (opera://plugins) ceases to display flash of ANY SORT, whereas 2) Chromium starts to show the up-to-date flash version AGAIN!

So in my strongly newbie analysis, I've reached a conclusion that "pepperflash-plugin" and "adobeflash-plugin" indeed compete against each other. Now I am just guessing, but I'd assume that the former would already include the latter, or at least be a modification of the latter. If there are two competing plugins on the system though, the system needs to select one.

Now recall back to the text file, the gedit file they were telling to create in one of the installation instructions. Wouldn't it make sense that the file is ought to be created TO DEFINE THE PREFERENCE ORDER of the existing plugins for the browser (in this case Chromium, but why not for Opera too)??

Well, as I said in my case, it didn't quite work as such for me, but on the other hand I had already removed all the rivalling competitors ("adobeflash-plugin", and there was also this "skunk")

Well, these are just newbies thoughts.

Ps. Thanks for the distro-update command It might solve the problem as well; actually I was waiting till the update can be carried out through an installed, but now after having played with the console a little bit - thanks to you - I think I might do it right now.

@perknh, yeppp! This is what "chrome://plugins" says in my Chromium:

Adobe Flash Player - Version: 21.0.0.216
Shockwave Flash 21.0 r0
Name: Shockwave Flash
Description: Shockwave Flash 21.0 r0
Version: 21.0.0.216
Location: /usr/lib/pepflashplugin-installer/libpepflashplayer.so
Type: PPAPI (out-of-process)

In my Opera, though, there's not flash at all in the list. Not even the 99.999.999.999 version, which I had earlier.

I know that Chrome would be an easy way to get everything in order, but I've been clinging stubbornly to the free-souce code version, Chromium. Well, Opera isn't actually free-source code, but I've been using it for other reasons ever since my days in the Windows camp.

@leocg thanks for your prompt reply!

Yeah, but I'm afraid GNOME Shell integration is one of them...

Greetings!

I'd need to install GNOME Shell integration (available for Chrome at least: https://chrome.google.com/webstore/search/gnome shell integration) and User Themes (https://extensions.gnome.org/extension/19/user-themes/), but it seems that this those aren't available to Opera — by default at least.

Having run Chromium before, there were no problems installing various GNOME extension via the browser. With Opera, however, it seems I've crashed into a brick wall.

The extensions I'd like to install are many. Dash to Dock, Hide Activities Button, No Topleft Hot Corner, Frippery Move Clock, Impatience, Topicons Redux, KStatusNotifierItem/AppIndicator Support, Pixel Saver, Sound percentage, just to name a few.

However, none of this is possible without GNOME Shell integration or User Themes, something that doesn't seem to be supporter by Opera, though. So what are my shots? My only chance is to switch to another browser, like Chromium?

I don't think so, and I hope you guys can help me out on that!

Cheers!

@zalex108 I've been now testing Group Your Tabs, but it isn't quite what I was looking for. See, I do have many tabs open, but usually they are from various different websites and domains; the only thing in common is the theme. For example, when you are making Google searches and you right click many prominent websites open into a new tab, that's the kind of organizing / grouping I need in my work - and a lot.

Even an empty tab in all it's simplicity would serve my needs perfectly! But Opera has changed empty tabs to Speed dial, and everytime I boot my system, the Speed dial tabs close

(19) None of the versions of Opera runs a site with flash even in the block exception list, and (20) Opera updated to 49 and now having flash player problems.

This is a result of a throughout and systematic investigation, not just some random sample. The earliest posts date back to 2014/12/03, and the newest one to 2017/11/27

@zalex108 Thanks chap! I wasn't quite aware of that! Let me keep trying from this stand, I'll let you know!

Cheers!

Up to my count, this is now the twentieth case report concerning the compatibility issues with Flash and Opera. There has been introduced a late resolution attempt by @natasha-from-dnepropetrovsk at the aforementioned link. I hope that works out for you folks!

Cheers!

Up to my count, this is now the nineteenth case report concerning the compatibility issues with Flash and Opera. There has been introduced a late resolution attempt by @natasha-from-dnepropetrovsk at the aforementioned link. I hope that works out for you folks.

Cheers!

@msxmaniac I ran /usr/bin/google-chrome-unstable --disable-bundled-ppapi-flash --always-authorize-plugins --allow-outdated-plugins --ppapi-in-process --enable-nacl --ppapi-flash-path=/usr/lib/adobe-flashplugin/libpepflashplayer.so --ppapi-flash-version=28.0.0.105 via Terminal. This is the output I receive:

bash: /usr/bin/google-chrome-unstable: No such file or directory

Any ideas...? Did I do something wrong, perhaps...?

Up to my count, this is now the eighteenth case report concerning the compatibility issues with Flash and Opera. There has been introduced a late resolution attempt by @natasha-from-dnepropetrovsk at the aforementioned link. I hope that works out for you folks!

@ said in New user Debian - Flash - Licence - Devices - Report:

Opera should use Flash that is installed on your system.

Use Debian Buster (Testing). I have Flash in all browsers. I do not have flash in Opera.

@Guest @leocg Unfortunately the Opera browser does not come with any pre-installed Flash of its own. There's a summary on the reported cases concerning the Flash compatibility problems with Opera, and so far the total count is eighteen cases.

You might want to try the latest instructions provided by @natasha-from-dnepropetrovsk perhaps? Just let me know if it works, we'll work something out!

Cheers!
