Ask HN: Getting started with local (non-cloud) movie and music collection?

For my home, I'd like to get started with a home movie and music collection. In particular, now that I have kids I'd like a curated collection and not have to rely on Prime/Netflix/Google.

A bunch of sub-questions: -Any good software/hardware for getting this setup? Prefer to have multiple devices in the house (iphone, computer) be able to access the "central storage" via wifi. -I'd like to grow a MP3 and digital movie collection. Any good "getting started" guides for getting those? E.g. ripping my CD and DVD collection. -I know my local library has some good content to incorporate... any other hidden gems of content?
