MarsSeed [1] filed a deletion request for lib32-schroedinger [2]: This 10+ year old library is not needed anymore. (Actually the major release v1.0 is from 2008.) Even Arch has orphaned it. Current FFMPEG/libavcodec source includes a better alternative of the Dirac codec (which is Schroedinger's purpose as well). But FFMPEG's code has been maintained and improved since. (Its current Dirac codec actually is based on an improved version called SMPTE VC-2, previously known as BBC Dirac Pro.) For its only AUR dependent, lib32-ffmpeg-semifull-git, I've already submitted a deletion request, since that is completely dead, with 15+ missing dependencies. (And that package is not needed anyway, as there are working and up-to-date lib32-ffmpeg AUR packages.)
