Rolling is ok. In this edition you will receive quick updates with fresh packages (just like in any other rolling distro).
guvcview is fixed and updated (thanks to @christopher_tanner for testing) Packages is now in testing repo. On Rolling you can install it from unsupported/testing repository.
So in om-repo-picker (or in terminal) you need enable “unsupported” repository and opt for testing.
Then install guvcview in dnfdragora, discover or via terminal: sudo dnf install guvcview
Skype
I have a question, did you install skype from skype.com? Right? If yes, please install it from system repository.
Enable non-free repo then: sudo dnf install get-skypeforlinux
btw. new skype version 8.56.0.103 is in testing repo too.
