dbermond [1] filed a deletion request for opencv-gstreamer [2]: I'm the maintainer of this package. This package should be deleted because the opencv package in the [extra] official repository switched xine/ffmpeg to gstreamer. No point on having it on the AUR anymore. https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/opencv&id=e11303e33a0d59bd22a5a07652c46185e773078e [1] https://aur.archlinux.org/account/dbermond/ [2] https://aur.archlinux.org/pkgbase/opencv-gstreamer/
