MarsSeed [1] filed a deletion request for com.seewo.easicamera [2]: EOL version from 3 years ago. Upstream stopped supporting Linux. No longer can connect to a remote classroom, this is now only a local webcamera previewer based on the broken python37 and a very old insecure Electron runtime. Not useful to keep. The latest Windows version can be used with wine. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/com.seewo.easicamera/
