The package currently fails to build due to an API incompatibility between the pinned librife-ncnn-vulkan submodule commit and the current ncnn library. The fix is to update librife-ncnn-vulkan to the latest master branch.

Reference: https://github.com/k4yt3x/video2x/commit/d848db037a797d68bdc3301798a0be1450398002

Clear yay's cache for this package

rm -rf ~/.cache/yay/video2x/

Go to a fresh directory

yay -G video2x cd video2x

Edit the PKGBUILD to update the submodule

prepare() { cd "${srcdir}/${pkgname}" git rm third_party/{ncnn,spdlog,boost} git submodule init

git config submodule.third_party/libreal_esrgan_ncnn_vulkan.url "${srcdir}/libreal-esrgan-ncnn-vulkan"
git config submodule.third_party/librealcugan_ncnn_vulkan.url "${srcdir}/librealcugan-ncnn-vulkan"
git config submodule.third_party/librife_ncnn_vulkan.url "${srcdir}/librife-ncnn-vulkan"

git -c protocol.file.allow=always submodule update

# THE FIX -> ADD THESE LINES TO UPDATE librife TO LATEST:
cd third_party/librife_ncnn_vulkan
git fetch origin
git checkout master
git pull origin master

}

Clean previous build artifacts (if any).

rm -rf src pkg

Rebuild with force flag

makepkg -sf sudo pacman -U video2x-6.4.0-3-x86_64.pkg.tar.zst

Broken currently, spdlog got upgraded to 1.17

video2x: error while loading shared libraries: libspdlog.so.1.16: cannot open shared object file: No such file or directory

It's already been fixed upstream but there's not been a release yet: https://github.com/k4yt3x/video2x/issues/1423

video2x-git package works

Does not seem to build anymore, seems ncnn installed is too new?

It's fixed in the librife-ncnn-vulkan git but that's not pulled and I don't know why.

Thanks @aviallon for adding me as a maintainer. The package has now been updated to 6.3.1.

k4yt3x commented on 2024-12-22 04:44 (UTC)

Hello there, I can maintain this package for the 6.x.x versions. I'm already actively maintaining the -git version, so I might as well keep this package up-to-date as well.

If you'd like, please add me as a maintainer and I'll update it to 6.3.1. Thanks for maintaining it thus far. I didn't really expect to see 4.x.x on Arch at all, amazing that you managed it.

It is outdated, the latest version is 6.1.1. For PKGBUILD update you can refer to video2x-git. If you need help, you can add me (or k4yt3x) as co-maintainer.
