Hi,
For about the last 2 weeks I have been having problems watching videos on Facebook in Opera. sometimes they will work in Firefox, and almost always in Chrome. Youtube seems to work on all of them, so I presume it is not an HTML5 problem.
Version of Opera is 54.0.2952.71. For info I have also tried to update the Codex files.
I am using Linux mint 18.3 64 bit
Thanks for any suggestion as it is anoying
Regards
Simon

It sounds like an outdated plugin. Try launching the browser from a terminal, attempt to watch a video, and then read the terminal output.

what codex files? please explain.
and shouldn't you be keeping your whole system up to date, and not only one file?

Hi,
Thanks for those comments.
Yes I do keep all the system up to date, I just updated to the latest version of codex to make sure the problem didn't come from there.
When I started Opera in the terminal, and then looked at a video it gave me no info at all.
I have read somewhere that there could be a patch problem between Opera and the video player, but have no idea how to correct it.
As Facebook is using H264 protocol and not HTML5
Thanks for all the help.
Would version 19 of Mint help?

i can only repeat my last question: what is this "codex" and how did you install it???

this doesn't make much sense. you cannot compare html5 (markup language) to h264 (video compression).

Hi,
Once again thank you.
Here is a copy of the codex files that are installed. I have done this via the synaptic manager.
I hope that you can see the attachement
or info if you cannot see it, it is:
Chromium-codecs-ffmpeg-extra 68.0.3440.75 OubuntoO 16.0.1., which according to my system is the latest version?
Kind regards
Simon

ok, this is a perfect example of why you shouldn't use textspeak (refered to as sms/l33t) on the forums.
i had no clue what you were talking about; but i was 100% sure that no package named "codex" would be relevant to your situation, or even exists.
had you written "codecs", my understanding would have been very different. but no, you repeated your mutilated version twice more despite my questions.

i'm out.

Thank you for that reply.
For your information I do not use textspeak, I made a genuine error using the English language, which you seem to bastardise.The word codex exists in English.
If you where aware that it should have been codecs why not say so.
I suppose it is that you didn't know the answer.
Why waste my time?

For those still looking for the solution here it is
Thanks to those that helped me. You forced me to find the solution on my own

Start Opera, goto, https://github.com/iteufel/nwjs-ffmp...uilt/releases/ and download the 0.31.4-linux-x64.zip file. In Opera's download dialog, click the folder icon to show the file in the file manager. Right-click it and choose "Extract here". This will give you libffmpeg.so.

Right-click in a blank spot in the file manager and choose "open as root" and type in your password. Then, right-click on libffmpeg.so and choose cut.

Then, in the file manager, browser to "/usr/lib/x86_64-linux-gnu/opera/". Right-click in a blank spot and choose to create a new folder named lib_extra. Once the folder is created, go into it, right-click on a blank spot and choose paste. You should then see libffmpeg.so there. Then, restart Opera and goto https://youtube.com/html5 to see if h.264 support is enabled for example. Then, test out some videos. On youtube, you can right-click on a video and choose "stats for nerds" to see if it's using vp9 or h.264. Or, you can try these h.264 videos to make sure they work.

You can then close the file manager.

Thank you very much Simon. This solutions worked for me too.

SimonWh awesome work, I think you have better skills than ondoho. Even I knew what you were saying when you typed codex instead of codec. Some people are just jerks and look for any reason to be negative. Anyway, you helped me out, and I appreciate you help and professional demeanor.

ondoho needs to stand in the corner and get a time out.

Funny how that happens. Feels good, doesn't it?

looks like in Debian the right place for lib_extra is
