This is a easy fix!

1. Download the last libffmpeg from here and decompress it.

2. Install at Opera directory, click at the top left corner at the Opera logo and About Opera, look at your Opera Installation path, on Debian is at /usr/lib/x86_64-linux-gnu/opera

3. Copy the libffmpeg.so to that path with:
   sudo cp libffmpeg.so /usr/lib/x86_64-linux-gnu/opera

4. Restart Opera
   

The fix is not permanent, for every Opera update you need to do this again.
For Debian there is no chromium codec and this libffmpeg is always up-to-date and align with Opera updates.

Try 54.0.2952.46. There's a video fix in the changelog.

After getting it all working I updated to that version - videos on Facebook broken again. Now there is an other release
(54.0.2952.51) available so will try that. If it is still broken I will try copying the same ffmpeg file again! What a palaver!

Yes, the libffmpeg get replaced in every update, here is what you can do.

• Download the last libffmpeg from here and extract some place.
• Do sudo mkdir -p /usr/lib/chromium-browser
• Copy the libffmpeg.so to that directory with sudo cp libffmpeg.so /usr/lib/chromium-browser
• Just to make sure run sudo chmod 555 /usr/lib/chromium-browser/libffmpeg.so followed by sudo ldconfig

That will keep you safe for a while unless there is some huge change in the libffmpeg.

Opera look in to this places for libffmpeg by default:

cat /usr/lib/x86_64-linux-gnu/opera/resources/ffmpeg_preload_config.json
[
  "lib_extra/libffmpeg.so",
  "/usr/lib/chromium-browser/libffmpeg.so",
  "/usr/lib/chromium-browser/libs/libffmpeg.so",
]

Why use nwjs-ffmpeg instead of chromium-codecs package?
Because nwjs-ffmpeg comes complete (11 MB) and works with linux distribution, chromium-codecs is about 3 MB and even if you installed over Debian (my case) it doesn't work for some reason.

Well,
Opera was updated to 54.0.2952.54, after the procedure above, there was no need to copy or download anything.
Everything is working as expected.

Last year I've made a post asking for support and I didn't have the time to look in to this, a month ago I gave Opera another try and with more time in hand I could crack this one for good.

Ubuntu is Debian based but is not Debian, so packages build for Ubuntu is not always available or compatible with Debian, forcing a install can brake the OS and cause a lot of trouble that people are not looking for.

This are the steps:

• Download the last flash player from Adobe and extract somewhere
• Create a folder at your home with mkdir -p ~/.config/flashplayer
• Copy the files libpepflashplayer.so and manifest.json to ~/.config/flashplayer with copy libpepflashplayer.so manifest.json ~/.config/flashplayer
• Create a system default flashplayer directory with sudo mkdir /usr/lib/adobe-flashplugin
• Link the files we need to that directory with sudo ln -s ~/.config/flashplayer/libpepflashplayer.so /usr/lib/adobe-flashplugin and sudo ln -s ~/.config/flashplayer/manifest.json /usr/lib/adobe-flashplugin

Flash player in Opera should work by now but it doesn't, Opera needs some environment information, for that we need some extra steps as follows:

• Edit ~/.bashrc and add the following at the end

export flash_library="/usr/lib/adobe-flashplugin/libpepflashplayer.so"
export flash_version=$(grep '"version":' /usr/lib/adobe-flashplugin/manifest.json | cut -d\" -f4)
export CHROMIUM_FLAGS="$CHROMIUM_FLAGS --ppapi-flash-path=$flash_library --ppapi-flash-version=$flash_version"

• Save, exit your session and start Opera

Goto to this site and click at Check Now, if you done all right, you should see the screen bellow:

Now every time you need to update the flashplayer, all you have to do is to copy the new files over the old ones at your own home at .config/flashplayer.

PS: It might not be necessary, but maybe your system may ask for this two fonts sudo apt-get install ttf-dejavu ttf-xfree86-nonfree

@goolash said in Opera 54.0.2952.41: Streaming videos don't work anymore:

I'v tried 0.33.(1,2,3,4) and 0.34.0 libffmpg that I'v got from here: https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/
(the screen was for reference only). Youtube crashes whenever I copy libffmpeg to Opera directory. If the ffmpeg is deleted videos are not working but the site does not crush.

Looks like there is a problem with his lib after version 0.32, download and install 0.31.5 and stay with it, you don't need to update it unless something stop working or there are some security related issues.

Just to make sure!
Opera version 54.0.2952.64 is working just fine!
Still using the same libffmpeg.so.

I believe you should learn to use the desktop environment you are at, this buttons are not provide by Opera but by the decoration setup from the environment you are using (Gnome, Kde, etc.)

On Debian you can setup to show or hide this buttons.

Updating...
Opera version 54.0.2952.60 is working just fine!

@burnout426 said in Opera 54.0.2952.41: Streaming videos don't work anymore:

Would be nice to have a script that detects the version of Chromium that Opera is using and fetches the latest compatible libfmpeg.so and installs it (in Opera's lib_extra folder so it doesn't interfere with any other programs and the version they need etc.).

For thouse outside the Ubuntu gang like Debian, Slackware, etc. Is possible to do this with cron once a month or whatever download the script would check the version, user system (32 or 64 bit), download, extract and install. No need for user interaction.

From my experience on Debian, you don't have to update that file to often.

Too bad I don't know how to code, but it shouldn't be a hard script to create.

@nova If you follow that post to the end, you'll see that you'll have to do that only once.

Yes, I know that works too!
I had a very bad experience with deb-multimedia.org, the apt decided to upgrade things using that repo and broke a lot of things on my system, so I pass. It took me a lot of time to discover that Opera requires that environment and not just the so in the right place.

Now the news is out there, there is no more need to use deb-multimedia.org and any Linux system can make use of it. I don't use flash anymore, my config is set to block it, but for those that need it.

It's possible to run scripts or commands apt after an upgrade or update comand:
https://unix.stackexchange.com/questions/70686/how-to-run-a-command-after-apt-get-upgrade

If people are so in need of flash, it's possible to create a script to update not only flash but libffmpeg also among with the trivial apt-get update && apt-get upgrade.

@zhochaka said in Opera 54.0.2952.51: another piece of crap! libffmpeg.so problem consists:

@bombacha My experience suggests that there may need to be an exact match of Opera and libffmpeg.so version

The version 0.31.4 didn't work with the previous version of Opera. It did work with the latest 54.0.2952.51 version.

That does make me wonder if the problem is more than just the wrong code being distributed.

Yes, a new lib doesn't work with previous releases, but a previous lib can work with new Opera releases. With new Opera releases many changes inside the code is done, fixes are made so the libffmpeg has to accommodate this changes that is some time incompatible with previous releases of Opera , it has nothing to do with wrong coding.

I think we may be slightly mixed up.

1: Why can't Opera work properly without getting a library-file from somewhere else? That suggests that, as distributed, it is supplied with the wrong code.

2: If the library has to be specially made to work with the opera calls, that feels as though the Opera code is badly written. It's missing the whole point of a library.

The first error should be easy to fix. The second feels a rather deeper problem.

S39Og2 answered while I was writing but I'll finish my point, Opera is a proprietary software, all the good stuff you want to watch over YouTube, Facebook and whatever uses proprietary algorithms and has NOTHING to do with bad coding.

You can also have a reference from ffmpeg site:
https://ffmpeg.org/legal.html

Q: Is it perfectly alright to incorporate the whole FFmpeg core into my own commercial product?
A: You might have a problem here. There have been cases where companies have used FFmpeg in their products. These companies found out that once you start trying to make money from patented technologies, the owners of the patents will come after their licensing fees. Notably, MPEG LA is vigilant and diligent about collecting for MPEG-related technologies.
