oech3 [1] filed a deletion request for nwjs-ffmpeg-codecs-bin [2]: Broken in principle. Aim of this is adding codecs to nwjs-bin without changing its license. However, nwjs does not have additional path to load this .so .
Every workarounds are belonging to user or nwjs-bin instead of this. If mainiatner of them is same, we should fix nwjs-bin (I requested). [1] https://aur.archlinux.org/account/oech3/ [2] https://aur.archlinux.org/pkgbase/nwjs-ffmpeg-codecs-bin/
