Settings
Settings is where Prismedia describes and edits app-wide behavior. Most controls are descriptor-driven so the UI, defaults, and persistence stay aligned.
Watched libraries
A watched library root is a container path plus scan behavior. Typical examples:
| Root | Scan toggles |
|---|---|
/media/movies | Videos |
/media/images | Images |
/media/books | Books |
/media/music | Audio |
Per-root settings:
| Setting | Meaning |
|---|---|
| Enabled | Disabled roots stay configured but are skipped. |
| Recursive | Walk subfolders. |
| Scan videos / images / books / audio | Independent media-type scanners. |
| NSFW | Marks media under the root as restricted by default. |
| Auto Identify | Whether this root participates in automatic identification during scans. |
How files become entities is covered in Library & Scanning.
Content visibility
Visibility controls whether NSFW content appears in browse pages, search, files, identify, plugin providers, relationship surfaces, and Jellyfin clients. Modes are designed for private LAN use:
- Hide restricted content by default.
- Show restricted content when explicitly enabled.
- Optionally auto-enable on trusted LAN access.
For Jellyfin clients, visibility is set per profile instead — see Jellyfin Profiles.
Playback
Playback settings cover direct/stream-copy/HLS behavior, adaptive transcoding (defaults to Auto), generated preview defaults, player preferences, and resume behavior.
Subtitles
Subtitle settings control:
- Auto-enable on playback.
- Preferred language order.
- Caption style, text size, vertical position, and transparency.
Video pages can apply local per-browser overrides from the player.
Generation pipeline
Generation settings control background work such as thumbnails, sprites, trickplay tiles, waveforms, subtitle extraction, fingerprints, and HLS output. These affect future scans and rebuild actions.
Fingerprints are split into two independent toggles:
| Fingerprint | Default | Notes |
|---|---|---|
| OpenSubtitles hash (oshash) | On | Reads only a small slice of each file — cheap. |
| MD5 checksum | Off | Must read every byte; the slow part of fingerprinting on large libraries. Turn it on only if you need it. |
Generated storage
Generated-storage diagnostics help you understand and refresh cached assets under /data — thumbnails, sprites, trickplay tiles, HLS renditions, waveform data, plugin artwork, and extracted subtitles.
Request services
Connect Radarr, Sonarr, and Lidarr instances for the Request workflow. Each service needs its URL and API key, and a required connection test verifies it and pulls its root folders, quality/metadata profiles, and tags before defaults can be chosen and the service saved. Per-service defaults cover the root folder, quality profile, search-on-request behavior, Arr tags applied to every request, and (Radarr) minimum availability. Multiple instances of the same type are supported; one per type is the default.
Worker
Worker settings include concurrency and scheduling behavior. Higher concurrency helps on large machines and hurts on small disks; raise it carefully. Changes apply without a restart.
API access
Manage the app API key (reveal, copy, regenerate) and Jellyfin profiles (create/edit/delete fake users with per-profile NSFW visibility and an enabled toggle). The API key authenticates /api/* calls and Jellyfin sign-in. See Authentication & API Keys and Jellyfin Profiles.
Diagnostics
Diagnostics show build/version/channel information, runtime state, update checks, storage actions, and maintenance controls. Include this information when filing bugs.
