As for the legality of that, not sure. I don't know if it was reviewed by Vivaldi's lawyers etc. or if they just do it and figure it's okay since Vivaldi isn't bundling it and only fetching it, so maybe that's considered okay.

As for Opera, I can only assume that they reviewed that idea and consider it too risky.

As for Firefox, I don't know, but I assume they use x.264 or something on the system.

As for Brave, don't know, but I think they might just bundle a libffmpeg with full media support. They might have a license or permission to do so or just do it anyway. Edge might do the same where they have a license.

I'm still searching. Anybody found something that works well?

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.

@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/

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.

Yeah - I've been using Opera since version 3 (when you had to pay actual money for it!) - it was a bit of a sad day when they dropped the Presto engine & reskinned Chromium - but after that setback, they pulled back most (maybe all) of the features I really liked about it. If it weren't for this libffmpeg thing, I'd say Opera's about as close as you can get to the perfect browser.

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.

Also see https://www.reddit.com/r/operabrowser/wiki/opera/linux_libffmpeg_config/ for ways to find a compatible libffmpeg.so in the future if needed.

I've been doing the "Use Chromium's libffmpeg.so" "trick" for several years; but after the last 2-3 updates (or so), if I copy across Chromium's version, Opera just crashes whenever it tries to play ANY video - even ones it is capable of by itself.

Looking for a new solution now
