New media added server-side was invisible while the app was open - the
client had no channel for library-change notifications, so the home
screen and library tabs sat stale until an app restart.
Each online server now runs a reconnecting websocket push channel
(Plex `/:/websockets/notifications`; Jellyfin/Emby `/socket` with the
dialect deltas, including Emby's capabilities registration), owned per
server by a LibraryEventService supervisor that follows server
online/offline/replaced-client transitions and app lifecycle. Channels
emit one coalesced LibraryChangeEvent per burst on a leading-edge
throttle modeled on Plex Web's repopulate pacing: the first settled
change surfaces immediately and a library scan's flood merges behind
it. Connection failure degrades silently to the stale-refresh paths -
bounded reconnect backoff, re-armed on every status sync.
Consumers pace their reaction through one shared RefreshPacer: burst
debounce, blocked retry while video playback or an active scroll owns
the surface, a cooldown bounding pass frequency during bulk imports,
and credit for committed pull passes so a push landing right after a
fresh load defers to the cooldown's trailing edge.
- Discover runs a debounced full pass and swaps the result in place;
the hero carousel resets only when a pass lands first content, so a
push never yanks a screen the user is reading. Pushed removals drop
from every visible list immediately via the deletion bus, scoped to
the emitting server.
- The visible library tab swaps its data in place: transaction tabs
reload without clearing, and the browse and paginated card grids
refetch their loaded span (Plex Web's repopulateRange) with the
scroll offset anchored on the first visible item and the span
clamped after alpha jumps. Hidden tabs - and tabs behind another
main tab - mark per-library staleness epochs instead and reload when
next shown; epochs are snapshotted at load start so a push racing an
in-flight fetch stays stale.
- The stale-resume and tab-shown paths refetch home hubs (previously
Continue Watching only), covering setups where the socket cannot
connect.

Jellyfin and Emby users had no way to record live TV from Plezy at all: no
record button in the EPG guide's program menu, and nothing in the recordings
UI, because every recording surface was gated behind a Plex-only DVR adapter.
The recording surfaces are now backed by a MediaBrowser DVR adapter that
synthesizes the neutral (Plex-shaped) payload models from the timer APIs:
- Template comes from `GET /LiveTv/Timers/Defaults?programId=`, offering a
"Record Episode" entry and, for series airings, "Record Series". The
defaults DTO travels JSON-encoded in the template's opaque `parameters`
and setting ids are DTO field names, so the existing template-driven
record-options sheet renders and round-trips them unchanged.
- Create POSTs the mutated defaults whole to `/LiveTv/Timers` or
`/LiveTv/SeriesTimers`; a duplicate one-off create answers 400, which the
adapter rethrows as `RecordingConflictException` so the sheet can show
"Already scheduled" without a backend check.
- Scheduled recordings read `/LiveTv/Timers` minus `Cancelled`/`Completed`
tombstones, rules read `/LiveTv/SeriesTimers` with their child timers
nested. Rule keys carry a `timer:`/`series:` prefix so cancel, edit and
delete dispatch to the right timer space inside the adapter.
Guide programs now carry their recording state: the program id doubles as the
record seed, and `TimerId`/`SeriesTimerId` become the rule keys that drive the
guide's scheduled dot and the Manage action. The series key is stamped only
when an airing actually records, so an episode a series rule skips does not
show a false indicator.
Three neutrality fixes on the shared UI: the record-options sheet only demands
a target library when the template declares one (MediaBrowser records into its
own configured folder), and "Re-evaluate rules" is hidden unless a connected
DVR supports it, since only Plex has that endpoint.
`fetchDvrs` deliberately stays empty so the synthesized per-server Live TV
identity that channel fetches, favorites and playback key off is preserved.
Verified end-to-end against a disposable jellyfin/jellyfin:10.11.11 container
with an M3U tuner and XMLTV guide, driven through the real client: template,
create, duplicate conflict, cancel, series create with child grabs, edit
round-trip and delete.

Scrubbing an Emby video showed no preview thumbnails on the timeline
while Plex and Jellyfin both worked: Emby's scrubThumbnails capability
was off, so the player never attempted a load. It was off because the
4.9.5 test server answered the preview endpoints with empty payloads —
its extraction task had not run.
Emby's preview transport is a Roku-format BIF at
/Videos/{id}/index.bif?Width=320, the same wire format Plex serves, so
the existing BIF parser handles it unchanged. Enable the capability and
route Emby previews through the shared BifThumbnailService, whose load
now takes a bytes callback instead of a Plex-typed client. MediaBrowser
sources also carry videoAspectRatio from the video stream so the
tooltip sizes itself to the stream. A server without extracted frames
still answers a header-only BIF, which parses to zero frames and keeps
the tooltip suppressed.

Emby is Jellyfin's upstream ancestor and speaks a near-identical MediaBrowser
API, so the existing Jellyfin stack is parameterised by a `MediaBrowserDialect`
rather than forked. `JellyfinClient`, its auth service, endpoint discovery, LAN
discovery, and the add/edit connection screens all take the dialect and keep one
implementation; `MediaBackend.emby` and `ConnectionKind.emby` carry it through
the neutral models, the Drift `kind` discriminator, downloads, and caches.
Every divergence below was measured against a live Emby 4.9.5 server, not
inferred from documentation, and each is documented at its capability getter.
Jellyfin's request strings stay byte-identical so nothing about its behaviour
changes.
Routes and auth
- Emby only accepts the pre-10.9 user-scoped item routes (`/Users/{id}/Items/…`,
`/Users/{id}/PlayedItems/…`, `/Users/{id}/FavoriteItems/…`); the unprefixed
forms Jellyfin 10.11 added return 404.
- The API is also served under a legacy `/emby` prefix, and both dialects accept
the token as `X-Emby-Token` or `api_key=`.
- Emby answers only its own LAN discovery datagram ("who is EmbyServer?") and
ignores Jellyfin's; its default HTTPS port is 8920.
- No `/QuickConnect` route exists, so Quick Connect stays Jellyfin-only.
Row fields Emby withholds
- `ProductionYear`, `OfficialRating`, `PremiereDate` and `DateCreated` are absent
from list rows unless named in `Fields`, which would otherwise strip the year
and age-rating badge from every card in the app.
- `UserData.LastPlayedDate` never appears on a list row under `Fields=UserData`,
`EnableUserData=true` or the user-scoped `Ids=` form — only on the single-item
detail route, or when the Emby-specific `UserDataLastPlayedDate` token is
requested. Without it every recency-ordered surface silently degrades to
library-add time, and `JellyfinApiCache.applyWatchState` stamps
`DateTime.now()` on watched rows, so an offline watch-state pull would rewrite
the cached play time of everything it walked.
Continue Watching and Next Up
- Emby computes Next Up per series only: the library-wide `/Shows/NextUp` query
returns nothing under every parameter combination tried. The shelf is
therefore reconstructed from a played-episode recency scan plus one
`/Shows/NextUp?SeriesId=` per distinct series, bounded by a shared wall clock
that covers the scan as well — per-request timeouts cannot bound the pass
because `MediaServerHttpClient` times the connect and receive phases
independently. Rows are stamped with their series' newest play from the same
response that ordered them, so no per-series enrichment request is needed.
- `/Shows/NextUp` ignores `NextUpDateCutoff`, and no server-side played-date
filter exists to delegate to (`MinDatePlayed` and `MinDateLastPlayed` are
ignored; `MinDateLastSaved`, `MinDateCreated` and `MinPremiereDate` filter
unrelated dates), so the 365-day window is applied to the scanned dates.
- The resume route returns items with no saved position, including plain next
episodes, so the Emby resume leg reads from `/Items?Filters=IsResumable`.
- Emby is ahead of Jellyfin in one place: `/Users/{id}/Items/{id}/HideFromResume`
makes Continue Watching removal a real capability.
Everything else
- `/Sessions/Playing` and `/Sessions/Playing/Progress` reject a body with no
`PlaySessionId` (HTTP 400), so playback reporting always sends one.
- Passing any `MediaTypes` value to the playlist query returns an empty list.
- There is no aggregate `/Items/Filters` route; the four filter facets are
reassembled from `/Genres`, `/OfficialRatings`, `/Studios` and `/Tags`.
- Metadata writes take name-pair lists (`Genres: [{'Name': 'Action'}]`); the
plain string array is accepted and then silently discarded.
- Custom artwork uploads must be base64 text, not raw bytes — which was broken
for Jellyfin too and is fixed for both.
- Trickplay, media segments and lyrics 404 on Emby, so scrub previews are absent
and intro/credit markers fall back to chapter names.
Verified against a local Emby 4.9.5 and a Jellyfin 10.11.11 control server:
onboarding, browse, detail, playable stream URLs serving real bytes, subtitle
sidecars, watch-state write and restore, hubs, cross-server aggregation and
search across both backends simultaneously.
- PaginatedCardGridTabState: the collections and playlists tabs were 95%
identical; they now supply only pageSize/fetchPage/idOf instead of each
duplicating the grid, memo, inflation budget and focus wiring.
- EtagCachedRemoteStore: the anime-lists and fribb mapping stores now share
one download/cache/isolate-parse/conditional-GET lifecycle.
- FocusableTileStateMixin manages its own initState/didUpdateWidget/dispose
instead of requiring every caller to forward three lifecycle hooks.
Also drops unused ServerCapabilities entries and dead code in
focusable_list_tile and music/track_row.
Introduces shared seams for paginated views, D-pad reorder, media control
routing, async singletons and the device method channel, then points the
open-coded copies at them.
Also removes unused models and duplicated provider/server plumbing, folds
the twice-implemented artifact store in the server, and factors the
repeated Flutter toolchain prologue in CI into a composite action.
