jholmer [1] filed an orphan request for vapoursynth-preview-git [2]: A request has been open to update the upstream for this repository for 6 months; the current upstream within the PKGBUILD has been dead for 18 months. Given that the package is completely broken at runtime as a result of this, it is believed that the maintainer is no longer active.
