dbermond  filed a orphan request for ffmpeg-qsv-git :
Maintainer seems missed. He does not answer a message from october 2017 warning that the package needs a fix.
Package is broken and needs maintenance. It currently fails to build because 'hardening-wrapper' was dropped from official repositories a lot of time ago (and also is not available on the AUR).
