External media controllers (Android Wear, Auto, Bluetooth dashes, lock-screen widgets) consume the audio_service MediaSession and silently no-op on any action that isn't in the handler's systemActions set. Several handler methods were already implemented but never advertised, plus stop() defaulted to a no-op — which matched user reports of "media controller on the watch sometimes works but doesn't play nice with Minstrel." This patch lines the advertised surface up with what the handler actually implements + wires a native heart-rating button. **Expanded controls + systemActions:** - Added MediaControl.stop to the expanded controls list. - systemActions now also enumerates stop, skipToQueueItem (override shipped in v2026.05.13.1), setShuffleMode, setRepeatMode, and setRating. Without these in the set, Android 13+ drops the corresponding callbacks from external surfaces. **stop() override:** halts _player and dismisses the foreground notification via super.stop(). Default just flipped processingState to idle without releasing the audio session — external surfaces treated that as "paused forever". **setRating wiring (native heart-button protocol):** new LikeBridge adapter passes through configure() carrying toggleTrackLike + isTrackLiked closures over LikesController and likedIdsProvider. - setRating override flips the like through the bridge and re-emits mediaItem so the watch's heart icon updates immediately. - _toMediaItem populates MediaItem.rating on every track change so the right filled/outlined heart shows on track-A → track-B. - PlayerActions ref.listen on likedIdsProvider calls refreshCurrentRating so toggling a like from TrackRow / kebab / another device (SSE) also keeps the watch icon in sync. **artUri seed on first broadcast:** AlbumCoverCache.peekCached returns the file path synchronously when the cover is already on disk. _toMediaItem uses this so warm-cache tracks broadcast with artUri populated from the first frame — external controllers see the cover immediately instead of waiting for the later async _loadArtForCurrentItem path. Cold-cache tracks fall through to that path unchanged.
Minstrel
A self-hosted music server that thinks for you. Smart shuffle, contextual likes, ListenBrainz-aware radio, and Lidarr automation — server-side, so every client (web, mobile, Subsonic third-party) gets the same intelligence.
State and intelligence belong on the server, not the client.
Highlights
- OpenSubsonic-compatible. Existing Subsonic clients (DSub, Symfonium, play:Sub, etc.) connect with no special configuration.
- Server-side smart shuffle. Track-similarity vectors, dual-like model (general + contextual), and session memory keep mixes coherent across devices.
- ListenBrainz radio. Session-aware "more like this" pulls from ListenBrainz similarity data, not a static genre tag.
- Lidarr integration. Triggered scans, request-driven album imports, and a quarantine flow when something doesn't fit.
- Built-in web SPA. Full-feature library, search, queue, playlists, and admin — no separate frontend container to deploy.
- Flutter mobile client in flight. Tracking issue #356.
Quickstart
# compose.yaml
services:
minstrel:
image: git.fabledsword.com/bvandeusen/minstrel:latest
ports: ['4533:4533']
volumes:
- ./music:/music:ro
- minstrel-data:/data
environment:
MINSTREL_DATABASE_URL: postgres://minstrel:minstrel@db:5432/minstrel?sslmode=disable
MINSTREL_LIBRARY_SCAN_PATHS: /music
depends_on: [db]
db:
image: postgres:17
environment:
POSTGRES_USER: minstrel
POSTGRES_PASSWORD: minstrel
POSTGRES_DB: minstrel
volumes: [pgdata:/var/lib/postgresql/data]
volumes:
minstrel-data:
pgdata:
docker compose up -d
After the stack is up, visit http://localhost:4533/register and create your admin account. The first user to register on a fresh instance is automatically marked as the administrator; subsequent users can register through the same form (or via invite tokens generated from the admin Users panel, depending on how you configure registration).
For the full configuration surface, see config.example.yaml.
Configuration
Most operators only need the env vars in the quickstart above. A few extras worth knowing:
MINSTREL_BRANDING_APP_NAME— rename the instance ("Family Jukebox", "Office Music"). Surfaces in the header, browser tab, and OG share previews.MINSTREL_STORAGE_DATA_DIR— defaults to./data. Holds playlist cover collages and other generated artefacts.MINSTREL_LIBRARY_SCAN_PATHS— colon-separated list of music library roots to scan. Supports multiple roots (/music:/podcasts).
ListenBrainz integration (per-user scrobble + similarity tokens) and Lidarr integration (URL + API key) are configured through the admin Settings UI rather than env vars or yaml — per Minstrel's "config in UI" rule, integration settings live where operators can edit them without restarting.
Most operational keys have a MINSTREL_<SECTION>_<FIELD> env override. Recommendation and events tuning are yaml-only. See config.example.yaml for the authoritative surface.
Updating
:main— rolling, follows the dev branch's tested tip. Recommended only for the operator who's running an upstream-watching deployment.:v1.0.x— pinned releases. Recommended default. Database migrations run automatically at startup; rollbacks require restoring a Postgres dump.
Specs
Authoritative scope lives under docs/:
- Server spec — current implementation focus.
- Client spec — Flutter companion app.
Development
Two concurrent dev processes:
- Backend:
docker compose up— Postgres + Minstrel on:4533. - Frontend:
cd web && npm install && npm run dev— Vite dev server on:5173with HMR. The Vite server proxies/api/*and/rest/*to:4533so session cookies work.
Production build
docker build -t minstrel . runs the SvelteKit build inside a node stage, copies the output into the golang stage, and //go:embeds it into the final binary. The container serves the SPA from / alongside the API surfaces; no separate static-file server is required.
Branches
- Day-to-day work happens on
dev(or feature branches merged intodev). mainis protected — changes land via PR fromdev.- Releases are cut by tagging
v*offmain; the release workflow builds and pushes the container image to the Forgejo registry.
Task and milestone tracking: Fable (Minstrel project, id 12).
