@krishnnadutt112 But where can I find the setting that forces Opera to change this language?
I don't see anything like that in the preferences (that's why I have to use the --lang option in Linux).
But I don't see any other options related to the language of the AI ​​itself.

@javickers said in libffmpeg.so needs to be changed every installation:

Oh, cool, thanks! I'll try that next time Opera gets an update...

If it happens that despite downloading the latest version of the ffmpeg file, the video still does not work, try using the previous version. The authors themselves inform that this may happen and that is how to proceed.

Well, you see, I gave you the link to version 0.101.2, but it turned out that this one doesn't work for me . So I went back to 0.101.1.

That's how it is with software. But generally, this method works well.

Does anyone know why, after forcing the browser to start in a specific language (the --lang option), the AI interface remains in English? This effect isn't present in Windows 11. It's a minor detail, but it's one of those annoying things.
Has anyone encountered this behavior?

Linux Mint 22.1 "Xia" x64
Opera 120.0.5543.93

@javickers There's no need to do any Google tricks.
Just download the file for Linux from this page
https://github.com/nwjs-ffmpeg-prebuilt/nwjs-ffmpeg-prebuilt
and upload it here
/usr/lib/x86_64-linux-gnu/opera/

I need the 64-bit file, so I downloaded this one 0.101.2-linux-x64.zip

At least for Linux Mint 22.1. Then restart Opera.

This always works for me, and I do it every time I update Opera. It's a pain, unfortunately. Opera is a rather odd browser; it has some good points and a few annoying ones.
