It's obviously not a streaming service in the normal use of the word, but the open source Jellyfin project (https://jellyfin.org/ https://jellyfin.org/) largely meets these goals with a few caveats: 1. This is mostly personal preference, but the way to resume previously playing media could be more obvious on startup 2. I'm unsure if it supports the "still frame" feature the author wants as I've never tried to do this 3. It doesn't really support lists, but arguably the media the user chooses to put on a Jellyfin server effectively acts as a list
