# =============================================================================
# MetaPlugin · Still Extractor — the `still-extractor` enrichment plugin, as a standalone app.
#
# A MetaMesh enrichment plugin is a HEADLESS worker: it speaks the four-verb
# plugin HTTP contract (`/manifest`, `/health`, `/configure`, `/process`) and
# nothing else. There is no dashboard — the web UI on this tile is the plugin's
# own `/manifest`, which is how you confirm it is alive and what version it is.
#
# ⚠ NOTHING IN THE FAMILY CONSUMES IT BY URL YET — install it knowing that.
# MetaSort starts its own plugin containers from `plugins.yml` (`image:`) and
# has no URL slot. The feeder SDK has exactly three sidecar slots
# (`FILENAME_PARSER_URL`, `TMDB_PLUGIN_URL`, `OPENSUBTITLES_PLUGIN_URL`) and
# `still-extractor` is not one of them. What this app gives you today is the plugin
# running and addressable at `http://metapluginstillextractor-plugin:8080` for anything that
# speaks the four-verb plugin contract — your own caller, a probe, a future
# consumer. It is packaging ahead of the consumer, on purpose.
#
# ⚠ IT HOLDS NO CREDENTIALS. The caller POSTs `/configure` with its own key
# (TMDB token, OpenSubtitles account) before use. Two consumers sharing one
# instance are last-writer-wins on that config — same key, no problem; different
# keys, install a second copy.
#
# Everything is scoped under the `metapluginstillextractor-*` prefix + the per-stack `metapluginstillextractor`
# network, so it installs beside the other Meta* apps with zero
# collisions.

**The `still-extractor` enrichment plugin for MetaMesh, as its own app.**
Grabs a representative frame out of a video and stores it as the record's `still` — a best-effort episode thumbnail.
It **never** writes `poster`: a still is a frame, not artwork, and the two
are different keys on purpose. One HTTP seek + decode per candidate offset.
**Headless.** It answers the plugin HTTP contract — `/manifest`, `/health`,
`/configure`, `/process` — and has no dashboard; this tile opens its
`/manifest`. Point a consumer at `http://metapluginstillextractor-plugin:8080`.
⚠ **No MetaMesh app calls it by URL yet.** MetaSort starts its own plugin
containers from `plugins.yml`, and the MetaFeeder SDK's sidecar slots cover
only filename-parser, TMDB and OpenSubtitles — not `still-extractor`. Installing this
gives you the plugin running and addressable on the `pcs` network for
anything that speaks the plugin contract; it does **not** add `still-extractor` to
MetaSort.

**Le plugin d'enrichissement `still-extractor` de MetaMesh, en app autonome.**
Extrait une image représentative d'une vidéo et l'enregistre comme `still` — une vignette d'épisode au mieux.
**Sans interface.** Il répond au contrat HTTP des plugins — `/manifest`,
`/health`, `/configure`, `/process` — et n'a pas de tableau de bord ; cette
tuile ouvre son `/manifest`. Dirigez un consommateur vers
`http://metapluginstillextractor-plugin:8080`.
**Ce n'est pas un plugin MetaSort** : MetaSort démarre ses propres
conteneurs de plugins depuis `plugins.yml` et n'accepte pas d'URL.

en_us: |
⚠ **Read this first: nothing calls `still-extractor` by URL yet.** MetaSort spawns
its own plugin containers from `plugins.yml` (`image:`) and has no URL
slot, and the MetaFeeder SDK's three sidecar slots are filename-parser,
TMDB and OpenSubtitles only. Install this if you want `still-extractor` running and
addressable at `http://metapluginstillextractor-plugin:8080` for your own caller — not
expecting it to light up MetaSort or a MetaFeeder on its own.
**Requires MetaCore** on the same box: this plugin writes what it
produces to MetaCore's WebDAV (`http://metacore-app:9000/webdav`).
**No web UI:** a headless service. Its consumers reach it directly on the
`pcs` network.
# Maison (Yundera dashboard) configuration. Read in preference to x-casaos.
# schema_version 2 is required for `folders`: an older Maison refuses the app
# outright rather than starting it without its directories.
