This free self-hosted app turned my Jellyfin server into a YouTube archive overnight

Pinchflat is a free self-hosted app that automates bulk downloading and archiving of YouTube channels and playlists. When paired with Jellyfin via SMB shares on a TrueNAS/Proxmox setup, it creates a personal YouTube archive accessible through a media server. The setup involves deploying Pinchflat via Docker, configuring SMB shares, and mapping the download folder to Jellyfin. Key features include per-channel profiles, configurable indexing frequency, resolution settings, and download logs. One caveat: storage consumption can be significant — 200GB accumulated in just a few hours at 1080p.
