Do we really need the 'celt' package?

Hi, Manjaro team!

I’m on the unstable branch, KDE, ordinary ISO (not minimal version).

I just got the batch of updates:

This repository is no longer used for active development.

Do we really need the outdated (cause 10 years w/o fixes and features in lossy audio matters) celt package?

Why we need the package?

If we need some functionality from the celt, then why not to use more modern opus (www.opus-codec.org) instead?

Thanks!

Possibly not.
As it’s an optional dependency, it’s easily removed.
Shouldn’t be a default package included in new installations though, if you ask me.

edit: Perhaps I need to clarify: celt was installed on my system, according to /var/log/pacman.log since this system was set up more than 2 years ago. It was listed as an optional dependency of jack.

I don’t have celt installed, so it probably isn’t.

But celt is a dependency of jack2, which the OP installed according to the output listed.

I am also do not have it in the image I used to install Manjaro. It was stable ISO image or unstable, I do not remember but it was certainly from June, 2021.

Please post the output of pacman -Qi jack2, so we can see what pulled in jack2 and thereby celt.

Nevermind.

I know what happened.

Jack2 recently got updated to replace regular jack. So you had jack installed, and it got replaced by a new package, that depends on celt.

Oh, I search the celt, but there is the libcelt0.so instead.

I did not install jack2 by myself. I got the update and agreed to upgrade from jack to jack2, so jack2 somehow need obsolete software package.

Right.

That’s correct.
