myc3l1um setup

Welcome.

Mycelium turns Seerr requests into Jellyfin-ready streams via TorBox in about 30 seconds. First, choose how you want to deploy it.

Full

React SPA + auto-scheduler + webplayer + trakt.
For users who browse and discover via the Mycelium interface.

Lite

Webhook + processor + /admin only. No SPA schedulers, no plugins.
For Seerr/Jellyfin-only setups where the SPA is not used.

If you'd rather edit .env directly, click Skip wizard at the bottom.

Quality & language

How should Mycelium rank candidates? You can tweak these per-show later via the Overrides tab.

Quality preference (in order) Comma-separated. Mycelium tries each in order until one is cached on TorBox.

Audio language preference Boosts releases with matching audio. Use ISO codes like nl, en, multi.

Prefer HEVC / x265 encodes
~40% smaller files at similar quality. Allow 4K releases
Large files, only sensible on fast LAN.

Catbox lazy mode

When enabled, torrents only enter TorBox when you press play, and leave after idle time. Lets your library grow unlimited while staying within TorBox's 30-day cache window.

Enable Catbox mode
Recommended once you've verified the basic flow works.

Catbox host (reachable from Jellyfin) This URL is written into .strm files. Must be reachable from your Jellyfin container.
