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.

Browsing artwork showed PMS PhotoTranscoder log lines flagged
"upscaled: 1" on every request. The flag merely echoes the upscale=1
query param Plezy sent on every cover request (PMS prints it before
locating the source, including on cache hits and pure downscales), but
the param had a real cost: whenever the requested box exceeded the
source — hero art at the 4K display budget (3840x2160 requests against
the near-universal 1920x1080 agent art), portrait backdrops on >1080p
phones — PMS genuinely enlarged the image server-side. Verified against
PMS 1.43: ~2.5x the transcode time and transfer bytes for zero rendered
detail, since the client covers the slot on the GPU regardless and the
fit-policy decode bounds never enlarge.
Send upscale=0 on cover requests too: downscale output is byte-identical
and oversized requests now return the native image. Jellyfin needs no
change — MaxWidth/MaxHeight never enlarge.
close#1975
Artist pages showed one flat album grid, unlike Plex's own clients.
Plex listing rows never carry Format/Subformat tags (even with
resolveTags=1), so fetchArtistDiscography follows the unchanged album
listing with one batched /library/metadata/{ids} request - whose rows
do include the tags - and classifies each album individually
(EP/Single, then live, then compilation, case-insensitively). A failed
tag fetch degrades to the flat list, and single-album artists skip the
lookup entirely. Jellyfin/Emby carry no album taxonomy on the wire and
return a single albums group.
The artist screen renders one titled section per non-empty group
(single-group artists keep the flat grid), with the grid focus index
space offset per section so D-pad traversal crosses section
boundaries.
PlayQueue was a freezed union whose Plex variant was never constructed (server queues flow through PlayQueueResponse), whose pattern getters had zero call sites, and whose backendId was written but never read — it is now a plain four-field LocalPlayQueue. The MediaItem compatibility factory re-listed the entire ~65-field union surface twice while every caller passes at most 22 fields; it now declares exactly that union. fetchLibraryContent had zero production callers (the UI pages through fetchLibraryPagedContent), so the interface method and both implementations are gone, with Jellyfin's drain folded into its paged entry point.
One server with overlapping libraries (movies in both an HD and a 4K
library, shows duplicated per language) returns search results that
cannot be told apart, forcing users to open each copy to find the
right one (#1970).
Each search row now carries a source line under the summary: backend
icon, server name, and library name, shown whenever the owning server
has more than one library. Plex rows name their section inline, with
sectionKey-only rows back-filled from the loaded libraries; Jellyfin
and Emby send no library field on search hits, so search always runs
the per-library scoped fan-out that previously only served
hidden-library exclusion and stamps every hit with its library. The
Jellyfin detail lookup adds a best-effort /Items/{id}/Ancestors stamp
so full metadata stays attributed, row refreshes merge instead of
dropping the stamp, and the mapper no longer misreads SeriesStudio or
ParentId as library identity.
Episode rows trade one summary line for the source line so the
wide-thumb row keeps its height, and the badge paints slightly below
the line-box center to sit on the text's optical middle.
close#1970
Videos take noticeably long to start. On Plex, tapping Play refetched
/library/metadata/{id} network-first even though the detail screen wrote
a strict superset of that exact payload under the same cache key seconds
earlier. On Jellyfin/Emby, playback start issued a full-detail item GET
before the PlaybackInfo negotiation, and the video controls issued the
same heavy GET again while the stream was opening (#1784) — the most
expensive queries a small home server serves, paid two to three times
per start.
Add ApiCache.getIfFresh over the existing cachedAt column and serve
rows younger than playbackMetadataCacheFreshness (5 min) without a
round trip. Plex guards with the strict stream-detail check
(_plexMetadataHasStreamDetail) so a thin row written by
getPlaybackExtras' lean fetch still goes to the network; Jellyfin's
row has a single full-shape writer, so fetchPlaybackBundle and
fetchPlaybackExtras share the new fetchItemFreshCacheFirst. Any miss,
stale, thin, or malformed row falls through to the unchanged
network-first path, and offline behavior is untouched.
Pausing an episode on one device, finishing it on another and pressing
Refresh left the first device showing the old "minutes left". Restarting the
app showed the right value. Two independent defects produce that, and either
alone reproduces the report.
The first is the watch-state overlay. Every local watch event lands in
WatchStateStore as a patch, and WatchStateSnapshot.apply overwrites
viewOffsetMs unconditionally; isNewerThan only ever orders one patch against
another, never against the server row underneath. Nothing expires a patch and
nothing clears the map except a profile switch, so the Mac's own paused
position kept winning over every subsequent fetch until the process died.
A patch exists to bridge the gap between a local action and the next server
read of that item, so it should stop applying once that read happens. The
store now records the watermark at which a successful authoritative response
returned each key, and suppresses an acknowledged session patch at or below
it. Only a watermark is stored, never the observed state: WatchStateSnapshot
cannot hold a container's leaf counts, and keeping max() per key makes the
order two concurrent responses complete irrelevant. Suppression is a
read-time predicate, so nothing mutates during build.
The barrier covers the parentChain too. patchForItem picks the newest of the
item's own entry and its ancestors', so retiring only the item's entry would
let an older season mark win and render watched/0 -- worse than either the
stale value or the fresh one. An authoritative read of a child already
reflects any container mark that preceded it, so the child's observation
judges its ancestors as well; a newer container action still wins.
Provenance decides what may be suppressed at all. WatchStateEvent now carries
serverAcknowledged, defaulting to false so an unclassified emit site degrades
to today's behaviour rather than silently becoming retireable. An offline
write is owed to the server and a read must never retire it, so it stays
until a WatchPatchPromotionNotifier promotion says the queue replayed it. That
channel is deliberately not a WatchStateEvent: OfflineWatchSyncService reacts
to watched/unwatched by purging queued progress, so replaying one there would
delete a newer rewatch. Promotion matches an exact WatchPatchId -- session
minted for live crossings, derived from the persisted (profile, row, revision)
for queued ones so it still joins after a restart.
Report acceptance is not delivery: PlaybackReportSession resolves true for a
same-state startup heartbeat it drops, so acknowledgement now keys on
onDelivered. A MediaBrowser Started saves play count and last-played date but
not the position, so it cannot acknowledge an offset. No report-derived
watched crossing is acknowledged on any backend -- Jellyfin hard-codes its
threshold and Plex never loads the server pref that would tell it the real
one -- so only an awaited explicit markWatched settles one.
The second defect is that a failed Refresh reported success. Plex _fetchHubs
and the Jellyfin hub legs both degrade a failure to an empty list, and the
library prefetch discarded its failures, so a server whose every hub request
failed was recorded as succeeded; DiscoverProvider then kept the previous rows,
set loaded and surfaced nothing. Worse, the background Continue Watching
refresh wiped the row outright on zero success.
Hub legs now report what they degraded through a HubFetchDiagnostics sink,
which keeps partial rows alongside the failure and leaves every existing
caller untouched. Failures ride through the aggregation results, a leg that
could not run because discovery failed contributes that failure rather than a
successful no-op, and loaded-server ids became succeeded - failed - cancelled
so one bad leg no longer caches a server as covered and blocks its retry. The
toolbar awaits a DiscoverRefreshOutcome and shows the existing unableToLoad
snackbar on failure while the retained rows stay on screen. Rollback after a
mid-pass exception is version-guarded, refilters against the current hidden
libraries and no longer publishes a system shelf the pass never committed.
Observations are staged with the pass and flushed only once the same disposal,
generation and exception checks that authorise committing those rows have
passed, so a discarded or rolled-back response can never suppress a patch.
Also fixes a live data-loss race the promotion work would have built on:
upsertProgressAction stamped a millisecond timestamp and updated the row in
place, so a rewatch queued during an in-flight replay was deleted by id.
Revisions are now strictly monotonic per row, replay deletes and retry updates
compare against them, and the upsert resets the retry fields because a new
revision is a new logical action.
close#1829
Marking a movie or episode watched left it sitting in Continue Watching with a
checkmark, and the only way to shift it was to play it and skip to the end.
Continue Watching membership on a MediaBrowser server is derived from
UserData.PlaybackPositionTicks alone; Played is never consulted. Marking played
normally zeroes that position as a side effect, so the row usually disappears
and nothing ever checked that it had. When something writes a position back
afterwards the item is left played *and* resumable, which the resume route
happily keeps returning forever. markWatched now reads the UserItemDataDto the
mark already returns and clears the bookmark itself when the server left one
behind, so the postcondition holds however the item got into that state. The
follow-up write costs a request only when the invariant is actually broken.
The writer putting items there is our own offline queue. insertWatchAction
already drops queued progress for an item when the mark is itself queued, but
the online mark writes straight to the server and queues nothing, so a progress
row recorded earlier survived and replayed afterwards — pending actions go out
oldest first — restoring the very position the mark had cleared. The sync
service now listens for watch-state events and discards queued progress for
that item as the mark lands. Progress recorded after a mark is a rewatch and is
queued later, so it is untouched. Plex never showed this because it forwards the
recorded-at timestamp and lets the server discard a stale replay; the
MediaBrowser stop report has nowhere to put one.
Continue Watching also drops the row locally now instead of waiting a round trip
for the refetch to confirm it, matching what removal events already did, and
marking a season or show takes its on-deck episode with it.
Watched items are deliberately still not filtered out of the shelf: Jellyfin
keeps Played set when new progress arrives, so a rewatch in progress is
indistinguishable from a stuck row, and filtering would hide it.
close#1812
Jellyfin has no equivalent of Plex's bundled `?includeOnDeck=1`, so a show
detail open chained `/Shows/NextUp` behind the item fetch and the screen sat
on a spinner for both round trips. The second one is not needed to paint:
everything except the play button's episode label comes from the item.
`fetchItemWithOnDeck` now takes an `onItemReady` callback and invokes it as
soon as the item is known, when that is strictly before on-deck settles.
Plex returns both together and never invokes it.
Phone and desktop only. TV keeps its own reveal gate — `_isTvDetailReadyToReveal`
holds the foreground at opacity 0 until extras, related hubs, seasons and the
first episode page have all loaded, and those still run after the on-deck
lookup settles, so TV sees no change. Both halves are pinned by tests.
Measured on a remote Jellyfin server, 15 interleaved show-detail opens per
version: time to content 1264ms -> 1042ms (-18%), with the rest of the load
unchanged.
Seasons and extras deliberately still start after the whole lookup settles.
Starting them at the early paint measured worse (time to settled +21%)
because they contend with the on-deck request instead of overlapping it — the
same reason `/Shows/NextUp` is not fired in parallel with the item fetch.
That trade-off is also why TV was left alone rather than being unblocked by
moving those loads earlier.
Two ordering hazards the early paint introduces, both covered by
`media_detail_screen_test.dart`:
- The early call must not write on-deck. `_loadFullMetadata` runs again after
playback, and clearing there would blank the play button for the length of
the round trip. `onDeckSettled` marks the authoritative write, so a reload
that finds the series finished still clears it.
- A settled empty on-deck must not drop the episode-derived fallback that
`_ensureFallbackOnDeckEpisode` supplies.
close#1784
Plezy reported a completed playback twice: the /:/timeline heartbeats let
the server mark the item played on its own, and the in-player auto-scrobble
then sent an explicit /:/scrobble for the same watch. On PMS 1.30 that adds
a second Play History row; on 1.43 the row is suppressed but viewCount still
lands on 2 for one playback.
Measured against PMS 1.43 to find what the server acts on: a watched-threshold
crossing observed inside one session. Consecutive above-threshold reports mark
nothing, a resume point left by an earlier session does not arm a new one, and
a report at position zero is inert while one at a single second is enough. So
the explicit mark now goes out only for sessions that gave the server no
crossing to observe.
That decision cannot be made while the session is live. A session beginning
past the threshold has no crossing yet, but rewinding and playing forward
creates one, and the server records it — marking eagerly and then hitting that
path leaves viewCount at 2 again. The mark is therefore deferred to the
terminal stop, and rides its future so callers that await the stop before
tearing the player down do not drop it. Deferring also covers a crossing
coalesced away during startup and a seek back below the threshold before
stopping.
Crossing state is tracked from reports the backend actually received rather
than from PlaybackReportSession.report()'s bool, which resolves true for a
same-state snapshot dropped during startup.
The same-file sibling hook (#1500) still runs exactly once, on the transition
to a settled mark rather than at the local crossing, so sibling episodes are
never marked watched while the episode actually played is not.
Local watched state and Continue Watching removal still happen on the observed
crossing, so the only behaviour that moves is the redundant server call.
close#1740
Jellyfin search rows do not expose their owning collection, so hidden libraries cannot be filtered after the response. Scope searches to visible libraries, stamp the returned rows, reuse the latest loaded views, propagate cancellation, and fail closed when views cannot be loaded.
Keep full candidate budgets and split music libraries into parallel album, audio, and artist requests. Album requests disable UserData and use the existing album field set to avoid recursive per-album work from #1552; audio requests retain cheap leaf play state.
close#1770
Jellyfin never consults IsAdministrator when authorizing a library
delete: BaseItem.IsAuthorizedToDelete looks at EnableContentDeletion and
the per-library grant, and only the first user a server creates gets the
former for free. Gating the "Delete from server" entry on the admin bit
therefore offered a destructive action that answers 401 to later
administrators, and hid it from plain users who do hold the grant.
Ask the server per item instead, through the new
MediaDeletionPermissionClient capability: BaseItemDto.CanDelete already
folds the global grant, the per-library grant, and item state such as
missing files or an in-progress recording. The probe runs when a menu
opens on a deletable kind, costs ~0.5 KB, carries a whole-request
deadline because the client's own budget covers connect and receive
separately, and fails closed on anything unknown. Plex keeps its
account-level owner/admin gate; it has no per-item permission on the
wire.
close#1749
`MediaServerClient.findByExternalIds` returned `MediaItem?`, so the Explore
"In these libraries" chooser could never show more than one copy per server.
A movie held by both a 4K library and an HD library on one Plex server
therefore resolved to whichever copy came back first, with no way to reach
the other.
Return every id-verified match instead. `/library/all` is already
server-wide and each `Metadata` entry carries its own `librarySectionID`,
so both copies come back labelled with no extra request; Plex was simply
taking `Metadata[0]` and the title ladder was returning on its first hit.
An exact-guid hit no longer short-circuits the title search either — a
library still on a legacy agent has a different primary guid and is
invisible to the `guid=` filter.
Copies are deduped by global key and ordered best-first, and each row now
states its resolution, since library names need not mention it.
Resolution passes merge rather than replace: the cross-server fan-out logs
and skips per-server failures, so a later pass can come back short a server
that answered an earlier one, and a failed pass no longer claims the title
left the library. Duplicate keys fold field by field, because Jellyfin's
library stamp is a best-effort ancestors lookup that returns the item bare
when it fails and an unstamped row is indistinguishable from its sibling.
Focus nodes are keyed by copy and reclaimed after a merge re-sorts the
rows, so a dpad user is not thrown to a different copy.
close#1754
The sheet collapsed an item to `Media.first` / `MediaSources.first` and
rendered a fixed set of rows, so split files, extra versions, per-track
properties, HDR classification and Dolby Vision were all invisible.
Model the payload the way both servers shape it — versions own parts,
parts own streams — and project every property either backend populates
onto `MediaStreamDetails`. The field set comes from sweeping both test
servers in full through the clients' own request shapes (Plex 6842
Media / 6842 Part / 39864 Stream entries, Jellyfin 6349 sources / 37763
streams / 61224 attachments), so file presence, Dolby Vision layers,
dynamic range, sample rate, spatial audio, sidecar provenance, embedded
attachments, rotation and the lyric stream type all survive. A coverage
test fails when a server key is neither carried, folded into a sibling,
nor excluded with a reason.
File Info also stopped trusting the shared `/library/metadata/{id}`
cache row: `getPlaybackExtras` writes it without `includeStreams` /
`checkFiles`, so the sheet could render with no stream table at all.
Detect that shape and refetch once under the request context captured
before the cache read, so the outgoing token and the cache namespace
stay on one profile.
Rework the layout to match: a summary chip row, then flat tonal cards
with a two-column field grid that collapses to one column on narrow
viewports, per-stream cards with flag chips, and a copyable monospace
path row. The card fill is a tonal step off the text colour rather than
the `bg` token, which is one shade from the sheet surface on OLED.
MAL/AniList season entries never matched the library show they belong to.
Both backends use the catalog title as a server-side filter before verifying
external ids, and a title like "Mushoku Tensei: Jobless Reincarnation Season 2"
cannot reach a show stored as "Mushoku Tensei: Jobless Reincarnation". Measured
against a 267-show Plex library, 3 of 113 mapped sequel entries matched.
The reverse lookup now takes two ordered title candidates instead of one: the
entry's own title and its season-stripped form, with typographic punctuation
normalised because both servers miss on a curly apostrophe. That matches 77 of
113. Widening it further to romaji/native/synonym variants reached only 81, so
the cap stays at two rather than spending up to five more requests per lookup
that finds nothing.
A sequel's year is its own season's, not the parent show's, so the +/-1 year
window is dropped for one - it would exclude the very show being looked for.
That also keeps a miss at the two requests the single-title lookup already
spent. A Plex Discover item additionally skips the title search entirely by
filtering on the plex:// guid its own rating key already is, which costs no
extra request and needs no cloud lookup.
A season 2+ entry only matches when the server really has that season, which
costs one children fetch on a match. Only a season both TVDB and TMDB agree on
is gated: which provider a library numbers its seasons by is a server setting
no dataset supplies and none of it is inferable from the ids an item exposes,
so a disagreeing reference is left ungated rather than gated on a guess.
The match cache is keyed per source and per entry rather than by canonical id,
which every season of a series shares: all five Mushoku Tensei entries collapse
to imdb:tt13293588, so one season-gated result would have poisoned the rest.
Entries whose Fribb row carries no provider id at all remain unmatched. That is
an upstream mapping gap, not something to guess around with extra lookups.
close#1704
Consolidates duplicated logic behind shared implementations — paginated
grid tabs, focus chrome, cached remote stores, sheet selection columns,
the server artifact store and a test fixture layer — and removes code
that had become unreachable. Net reduction of about 5,500 lines with no
behaviour change.
Where a fix had landed separately in code that moved into a shared
helper, the fix was re-applied inside the helper rather than left behind
in the copy that went away.
- 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.
Drops dead code across services, models, utils and widgets, including the
connection auth service, which had no implementer, and the Live TV DVR
provisioning models, which had no caller.
Tests that only covered deleted behaviour are removed or trimmed. No
behaviour change.
