@brainmue, @asm0dey:

I cannot reproduce the errors. Tried it in a clean chroot build environment and on a fresh install. ffmppeg-normalize migrated to "uv", a newer Python package manager.

If you can, as a test, add this to the PKGBUILD file and then build again:

EDIT

prepare() {
  rm -rf $pkgname-$pkgver/dist                  
}

Otherwise, try to update the system and delete the build cache files (~/.cache/yay/ffmpeg-normalize or /var/tmp/pamac-build-weiller/ffmpeg-normalize).

For me it fails the following way:

First of all, thank you for this great project. I use it very often and am completely satisfied with it. Thank you for all your hard work.

Unfortunately, the current version (1.33.1-1) causes an error when I compile it.

==> Beginne build()...
Building wheel...
Traceback (most recent call last):
  File "<string>", line 8, in <module>
    import uv_build as backend
ModuleNotFoundError: No module named 'uv_build'

  ├─▶ The build backend returned an error
  ╰─▶ Call to `uv_build.build_wheel` failed (exit status: 1)

      hint: This error likely indicates that `ffmpeg-normalize@1.33.1` depends on `uv_build`, but doesn't declare it as a build
      dependency. If `ffmpeg-normalize` is a first-party package, consider adding `uv_build` to its `build-system.requires`. Otherwise,
      either add it to your `pyproject.toml` under:

      [tool.uv.extra-build-dependencies]
      ffmpeg-normalize = ["uv_build"]

      or `uv pip install uv_build` into the environment and re-run with `--no-build-isolation`.

Is it possible that the dependency on python-uv-build is missing here?

Strange. I don't have to do that. Checked it with makepkg in a clean chroot build environment and with paru. Maybe cleaning up build files or the build cache will help.

The check function still fails. I got it to work by adding the line

mkdir tests/normalized

between the cd and the pytest lines.

@aaruni96: Thanks. Fixed.

I can not install / update this package to version 1.33.0-1. The error I get is related to test files not being found ?

Thanks, I needed to rebuild python-ffmpeg-progress-yield.

@chungy:

checkrebuild is in package rebuild-detector. It will also automatically warn you during a system upgrade. Very useful.

Or try this: pacman -Ql python-ffmpeg-progress-yield should list files in /usr/lib/python3.13, not in /usr/lib/python3.12 in which case that package needs to be rebuilt.

@williemw I don't have that command.
