mhdi [1] filed a deletion request for droidcam-dev [2]: This package is a duplicate of aur/droidcam. The `-dev` prefix in the package name is redundant, since there is no upstream dev release. The main difference between this package and aur/droidcam is that the latter installs the binary to /usr/bin, while this one installs it to /opt.
