loissascha/localstream ? reverse-engineered prompt

Build me a self hosted app for streaming my local movies and TV shows.

I want it to scan a folder of video files, show my library in a simple web app, play videos smoothly with support for seeking, and remember where I left off so I can continue later. It should pull posters, titles, and episode info from TVMaze for shows and TMDB for movies, and store the library and watch progress in PostgreSQL.

Use a Go backend and a SvelteKit frontend, and make it work nicely for home network use. In production the Go server should serve both the API and the built frontend from the same app, so it is easy to run on something like a home server or through a Tailscale address. In development, let the frontend talk to the backend through an API URL. Keep the UI clean and simple, and make sure the app can handle local file paths and basic media library management without needing any cloud service.
