A quality preset the source already fits under direct plays the file
since #2152, but a transcode above the source bitrate is sometimes the
point: a device that cannot decode the source (10-bit H.264, AV1, 4:4:4)
wants the server's highest-quality encode, and the shortcut silently
handed it the very file it cannot play smoothly.
A new Quality switch, "Play Smaller Videos at Original Quality" (on by
default), gates the shortcut in PlexClient._presetNeedsTranscode; off
restores the pre-#2152 behavior where any non-original preset always
transcodes. Plex-only by design: MediaBrowser servers make the
equivalent direct-play-vs-transcode call server-side.

The brightness set with the left-edge swipe was lost the moment playback
ended, so every session started back at the system level. A new
"Remember Brightness Level" toggle under Settings > Playback > Gestures
persists the level a swipe settles on and reapplies it when the next
playback starts (and when the app resumes mid-session). Leaving the
player still restores the pre-playback brightness, so the rest of the
app is unaffected. Default off, preserving current behavior.

Quitting the app lost the music session: on the next launch the queue,
current song, and playhead were gone. The session now persists per
profile (new MusicSessions Drift table, schema v22) through throttled
write-through during playback, and the next launch rehydrates it as a
parked-paused queue — no audio core and no source resolution until the
first play, which opens the track at the saved offset. Ending the
session (stop, swipe-dismiss, video claim) clears the snapshot, and a
new "Remember music session" playback setting (default on) gates the
restore.

Users could not adjust the five-second Play Next timer, switch off the
edge-swipe/pinch gestures they trigger by accident, deinterlace DVD-era
content, or keep always-on-top across episodes.
Play Next Countdown (0-30 s) joins Auto-Play & Skip; zero skips the
prompt and starts the next episode immediately, while the transient-
retry prompt keeps its fixed five-second spacing. Brightness swipe,
volume swipe, and pinch-to-zoom each get a switch in a mobile-only
Gestures group; a disabled edge also stops stealing the content-strip
drag. A Deinterlacing toggle (mpv-only — ExoPlayer has no filter chain)
sets mpv's deinterlace=auto at player init. The player's always-on-top
toggle now persists via a pref that is re-applied when the next player
opens, including autoplay episode transitions; the window flag is still
dropped when the player closes.
Also resolves the reorg TODO markers per triage: hold-to-speed lock
(#1046) will be gesture behavior rather than a setting, metadata
language (#1668) and delete re-authentication (#1924) are rejected, and
always-on-top is player-persisted state, not a Window setting (#1386).

Settings were grouped by screen history rather than by what they govern:
the profile-selection prompt, startup section, force-TV mode, and app
language sat under Appearance, Discord Rich Presence and the companion
remote host hid inside Playback > Behavior, and maximum volume lived
under Seek & Timing.
Introduce a General screen (language, startup, desktop window), regroup
Appearance into display/library/home/navigation/Live TV, split the
Playback monolith into engine, video & display, audio, quality,
subtitles, seek, auto-play & skip, and behavior groups, surface
auto-play next episode in settings, rename the Keyboard Shortcuts
section to Controls (now also hosting the companion remote host), move
Discord Rich Presence to Services > Integrations, and move the
performance-overlay switch to Advanced. Pref keys are unchanged, so
stored values, export/import, and reset behavior are unaffected.
TODO markers record the agreed homes for upcoming settings (#1998,
#2064, #1641, #1769, #2149, #1827, #2138, #1810, #1046, #1924, #1413,
#1668, #1386, #1795).
On mobile data the single default streaming quality either burns
through the user's data plan or permanently caps quality at home.
Playback start now applies a dedicated cellular default when the
device is on a cellular-only connection, read from the app's existing
single connectivity subscription. The new setting defaults to
following the general default, ships in Settings > Playback for
phones/tablets only, and explicit per-play quality picks still win.
'Metered connection' had been spelled out independently in the offline
provider, the download WiFi-only gate and the sync-rule cooldown.
Rather than add a fourth copy, all four now share
ConnectivityLinkType. Network *presence* is deliberately left alone:
its callers disagree on whether an empty snapshot counts as
connected, so folding that in would change behavior.
showSelectionDialog now returns the picked DialogOption instead of its
raw value so the tile's null-valued 'Same as Default Quality' option
stays distinguishable from dismissing the dialog.

The library grid packs posters edge to edge. The grid delegate's cross-
and main-axis spacing were hardcoded to zero, so the only visible gap
came from each card's own 3px padding, and Library Density changed
poster size rather than the space between posters. The result reads
denser than Plex, Jellyfin, or any commercial client, both horizontally
between posters and vertically between a poster and its title.
Add a Grid Spacing setting - Tight, Normal, Spacious (0/6/12px) - below
Library Density. Tight is the default and reproduces the current layout
exactly, so no existing grid moves on update.
The gutter lands in MediaGridDelegate.spacingFor(), already the single
funnel for non-full-bleed grid spacing, so every grid surface picks it
up: library browse, collections, playlists, downloads, and the detail
screens. Square music grids keep their 8px floor. The pref is watched
once in MediaCardSliverLayout - the only MediaGridGeometry.resolve()
call site - so grids re-layout live instead of on restart.
Grid cells grow the poster-to-title gap to 2/4/6px as well; the
Expanded poster absorbs the delta, so the cell keeps its aspect ratio.
Fixed-height hub-row cards keep the historical 2px because their text
band cannot absorb more, and hub-row cell packing opts out of the
setting entirely so shelves stay byte-identical across it.
Full-bleed TV grids are untouched - they already carry an 8-18px
scale-derived gutter - and are opt-in behind tvFullCardLayout, so the
default TV library grid follows the setting like every other surface.
Verified on macOS across all three steps: gutters and title gap grow,
grids re-pack live, and the segmented control reflects and writes the
value.

The in-app FFmpeg container demuxer classified every DTS variant as
plain DTS (profile-blind MIME mapping at the demux boundary), so
DTS-HD MA lost its lossless identity downstream, and it ignored
container display-aspect-ratio overrides. media3's extractors get both
right.
Delete the FFmpeg demuxer (JNI, extractor, and its setting); ExoPlayer
direct play demuxes with media3's DefaultExtractorsFactory again, and
mpv - the Android default - reads container display dimensions itself.

Android mpv drew every frame through vo=gpu: an ImageReader/GLES copy
pinned to 8-bit RGB0 with a 100 ms timed wait per frame, which
truncated 10-bit and HDR output, raced acquireLatestImage, and
performed badly on low-end TVs.
Video now scans out on a SurfaceFlinger video plane through the fork's
vo=mediacodec: decoder buffers are queued to the surface at their
target PTS (av_mediacodec_release_buffer_at_time), so 10-bit and HDR
dataspaces reach the display untouched and frame pacing no longer
depends on GL vsync. Subtitles and OSD render on a sibling transparent
surface presented for the same PTS, frame-locked by construction.
The plane takes decoder buffers only, so software-decoded video stays
on a GL vo, with a chain-failure watchdog re-initializing the output
when the plane refuses a stream mid-session. The GL fallback is vo=gpu
- gpu-next breaks the Tegra GLES linker (#2010) - and GpuVoPolicy
selects gpu-next only when Dolby Vision RPU reshaping needs
libplacebo. AV1 film grain is applied in the decoder
(vd-lavc-film-grain=cpu) because the GL raster grain fallback is not
available on this path.
Pins libmpv-android v1.1.3, which carries the fork patches this path
rides on: the vo itself, BT2020-PQ EGL window surfaces, GLES direct
rendering treated as slow (H.264 Hi10P software decode on Tegra went
from 0.3x realtime with wrong colors to 1.0x with correct 10-bit
output), and multichannel IEC61937 for ao_audiotrack.
Verified on Shield Pro (Tegra/GLES), Pixel 7 (Mali), Box R 4K Plus
(Amlogic armv7), and Galaxy Z Fold3 (Adreno): 520 play/teardown cycles
and 3 hours of continuous 4K HDR playback; HDR engagement confirmed
via SurfaceFlinger dataspace BT2020_ITU_PQ.
A device with no hardware HEVC decoder could still be handed an HEVC
transcode: the device profile advertised a fixed codec list that assumed
every device decodes everything. Prepending AV1 to reach the AV1 encoders
issue #2131 asks for would have made that worse - an Apple TV 4K and every
iPhone before the A17 Pro have no AV1 decoder at all.
Probe the platform instead. Android enumerates MediaCodecList for a
hardware decoder and iOS/tvOS ask VideoToolbox, both feeding one latched
VideoDecodeCapabilities that the device profile reads when it builds its
codec lists. Desktop deliberately answers nothing: a pre-Kaby-Lake Mac has
no hardware HEVC decoder and an M1 no AV1 one, yet both software-decode in
real time, so narrowing there would force transcodes for nothing. An
unanswered or failed probe advertises everything, so the list never
narrows on missing data.
The transcode target becomes av1,hevc,h264 filtered by the probe. Leading
with AV1 is safe because the server rotates codecs its admin has not
enabled ("Allow encoding in HEVC/AV1 format", both off by default) to the
back before picking one, so it costs nothing on a server that will not
emit AV1.
Audio now accepts everything the path can carry. The direct-play profile
drops its AudioCodec list entirely - an omitted list means "any codec" to
Jellyfin - so an audio stream can no longer be what blocks direct play.
The transcode target lists every codec Jellyfin can put in an fMP4
segment, so a video-only transcode copies DTS or TrueHD instead of
re-encoding it. Two limits bound that string: the server validates it
against ^[a-zA-Z0-9\-\._,|]{0,40}$ when it echoes the list into the
transcode URL, so alac does not fit and * is not a wildcard; and omitting
the key is not "accept everything" here the way it is for direct play,
because the server substitutes the source codec and then ships no audio at
all for a source fMP4 cannot carry.
close#2131
Preferences that belong to the media-server account had nowhere to live in Plezy. Jellyfin keeps a user's audio/subtitle language, subtitle mode and several library options in `UserConfiguration`; plex.tv keeps the same language choices plus watched indicators and review visibility on the account. Plezy read four of those fields for auto-track selection and could never show or change any of them.
Adds an Account preferences section under Connections. One account edits in place; several show a picker first, scoped to the active profile's own connections so a managed Plex Home user never edits the owner's record. Every row is gated on what the backend can actually store.
It also moves "rewatching in Next Up" onto the account. There is no `UserConfiguration` field for it, but the per-user `DisplayPreferences` store is keyed `(userId, displayPreferencesId, client)` with no device component, so the switch goes there and follows the account.
`AccountRef` keys by account, not `clientScopeId`: MediaBrowser is `{machineId}/{userId}`, Plex is (account, Home user). Writes are patch-shaped because both backends replace whole objects — Jellyfin's `POST /Users/{id}/Configuration` and its `DisplayPreferences` row both reset omitted fields, so each write re-reads, merges only the patched keys, and posts back. Plex takes its changes as query parameters with an empty body, and its `experience` blob and the PMS `/accounts/1` mirror are deliberately untouched.
`AccountPreferencesController` owns a single repository above the profile session, so changing a language in settings reaches the next playback without a restart. Emby is gated out of rewatching through `MediaBrowserDialect.supportsNextUpRewatching`.

Linking a Seerr instance had two rough edges, both on the Jellyfin path.
The URL step prepended https:// to anything without a scheme, so a
plain-HTTP instance on the LAN — 192.168.1.5:5055, or a bare host on
Seerr's default port — failed with "could not reach" unless the user knew
to type the scheme. And the only way to sign in with a Jellyfin account
was typing a username and password, which on a TV remote is misery.
Schemeless input now expands into candidates that are probed together,
but TLS wins by construction: a plaintext success is held while any https
candidate is still in flight and is accepted only once they have all
failed. The sign-in that follows posts a password to whichever URL wins
here, so a slow-but-working https endpoint has to beat a fast plaintext
one, and the wait is already bounded by the probe timeout. When nothing
answers, the failure that reached a server outranks a transport error, so
"this instance has not completed first-run setup" is not masked by "could
not reach https://..." from a candidate the user never typed.
Quick Connect goes through Seerr's own proxy routes (3.4+): initiate,
then check polled at Seerr's own 2s cadence through the shared
pollWithBackoff — a 404 mid-poll means the secret is gone and is terminal
— then authenticate, which mints the session cookie through the existing
sign-in path. The secret rides in a query string, so it is registered for
log redaction the way the Jellyfin flow registers its own. An instance
that predates the routes 404s the initiate and is told apart from a
generic rejection.
SeerrAuthMethod.quickConnect deliberately stores no secret: silent
re-auth is impossible by construction, so an expired cookie lands in the
existing "no stored credentials" arm, unlinks the session, and the
connect flow asks for a fresh code. The affordance is limited to the
Jellyfin credential form, since Seerr rejects Quick Connect for Emby, and
is not auto-started on TV the way the MediaBrowser form is:
/settings/public exposes no "Quick Connect enabled" flag to gate that on.
The waiting panel and its attempt/cancel bookkeeping moved out of
AddJellyfinScreen into QuickConnectCodePanel and QuickConnectFlowMixin so
both screens share one implementation, and the post-frame focus helper
both forms use moved to AsyncFormStateMixin.
Sub-4K content on a 4K TV was always upscaled by the playback device, so the TV's own (usually better) upscaler never received the native signal and could not apply resolution-specific processing.
Adds a Match Content Resolution setting on Android TV: playback picks the smallest display mode that still contains the video — never downscaling it — and rate-matches within that resolution when frame rate matching is also enabled. A resolution-only switch keeps the refresh rate as close to the current one as possible, and the settle watchdog now verifies the requested mode id so such switches still trigger the Android MPV decoder refresh. Transcodes get their target from decoded dimensions on the post-first-frame path. Mode selection is extracted into a pure, JVM-tested DisplayModeSelector.
close#2073
PR #1666 merged without compiling: it maps existing connections into the
add-server discovered list, but DiscoveredJellyfinServer gained a required
dialect with the Emby backend. Carry the connection's dialect through and
list only connections matching the screen's dialect, so the Add Emby screen
does not offer existing Jellyfin servers.
The backend cards drew the outline focus border; the wrapper now sits
inside the opaque Material with useBackgroundFocus so the fill paints
above the surface, matching the other settings surfaces.
The Auto demuxer mode routed only media3's weak container families
(AVI, ASF/WMV, MPEG-PS, Matroska/WebM) through FFmpeg and kept MP4/TS
on media3's extractors, with a second any-container FFmpeg instance
behind media3's list. With the goal of fully switching to the ffmpeg
demuxer, the split served no purpose and the catch-all could never add
coverage once the primary accepts everything.
Collapse the preference to two modes: FFmpeg (default), which demuxes
every progressive container ahead of media3's list, and media3 only as
the user-facing escape hatch in case a file misbehaves. media3's
extractors stay behind FFmpeg, so anything FFmpeg cannot sniff still
reaches them. The catch-all role and the Auto container list are
removed; unknown persisted wire values (including the retired "auto")
resolve to FFmpeg.
Verified on a Pixel 7: MP4, TS, and MKV all demux through FFmpeg under
the default ("sniff accepted mov,mp4 / mpegts / matroska,webm") with
forward and backward seeks landing; JVM suites and analyzer pass.
Direct play on Android kept accumulating container patches: AVI with
XviD packed-bitstream timestamps and missing VOL csd played broken,
ASF/WMV and MPEG-PS/VOB had no media3 extractor at all, and MKV needed
a custom extractor stack for zlib-compressed subtitles, LOAS/LATM
audio, cueless seeking, and font attachments.
Demux progressive containers with libavformat behind media3's
extractor API. An AVIO bridge serves libavformat from the
ExtractorInput: every position divergence defers into a RESULT_SEEK
round trip, header reads replay from a block cache while
avformat_open_input restarts, and avformat_seek_file executes seeks
with bounded loader round trips. Packets feed media3's TrackOutputs,
so decoders, passthrough carriers, Dolby Vision RPU/EL conversion
(dvh1 codecs string surfaced from DOVI side data), and the subtitle
pipeline are untouched: embedded fonts feed AssHandler over JNI, ASS
reaches libass as per-sample dialogue, SRT/VTT render as cues, VobSub
maps through media3's VobsubParser, and LOAS/LATM AAC unwraps via
LatmTrackOutput.
Under the default Auto preference FFmpeg demuxes AVI, ASF/WMV,
MPEG-PS, and Matroska/WebM and sits behind media3's list as an
any-container fallback; MP4/TS keep media3's extractors. A playback
setting exposes auto / FFmpeg first / media3 only, and the JNI
load-failure path falls back to stock media3. The custom Matroska
extractor stack and its reflection keeps are retired.
Verified on Pixel 7 (API 36), Box R 4K Plus TV (API 34), and SHIELD
TV (API 30): instrumentation playback suites, the minified R8
reachability gate, and an on-device container matrix with forward and
backward seek landings plus visual subtitle checks.

Jellyseerr shifts MediaStatus codes 6/7 relative to Overseerr (6=blocklisted, 7=deleted vs 6=deleted), and the shared unconditional mapping misread both. The product is now detected from the presence of mediaServerType in /settings/public, persisted on the session, and used to resolve raw wire codes; blocklisted titles are shown as non-requestable.
Request statuses failed(4) and completed(5) previously decoded as pending, blocking re-requests and mislabeling failures; both are now modeled and active requests are defined positively as pending or approved. Seerr also marks a request Failed on arr-push failure while leaving the media status Processing, and precedence checked processing first, so failed titles rendered as Processing and the request sheet kept blocking re-requests; a failed request with no live pending/approved request now wins over stale pipeline status in both the catalog state and the sheet's blocked labels.
Reauthentication completing from a stale session snapshot wholesale-replaced the session and could downgrade a concurrently detected product discriminator back to unknown permanently (the settings cache never reapplies it); adoption now merges the known product.
Queued tracker writes carried no account identity, so rows created under account A replayed against account B after a reconnect; explicit disconnect now purges that service's queue. An in-flight markWatched/reconcile that failed after the purge was re-enqueued anyway (the write scope only tracked profile generation) and replayed into whichever account connected next: Tracker.accountBinding (client identity, rebound synchronously on every disconnect) is captured before each write and re-checked before queueing a retry, and because the check sits in the same synchronous segment as the enqueue, a row that passes it is claimed ahead of the purge in the queue mutex and is still removed by it.
The memoized anime-list snapshot survived writes, so sequential rewatch updates computed from pre-write state; successful writes now evict the entry.
A device-code dialog dismissed by system back never cancelled the poll (blocking new attempts until the deadline), and a user-cancelled sign-in showed the connection-failed snackbar; both now route through one cancel path.
A cleared skip-marker regex saved as an empty pattern, and RegExp('') matches every chapter title: all synthetic markers became intros or credits, and an end-of-file credits marker could auto-advance the episode. Blank input is now rejected at both validation and save, and the chapter fallback treats already-persisted blank patterns as absent.
Changing playback speed, shader preset, aspect ratio, or a sync offset in
the player always rewrote the global default, so a show watched at 1.5x
forced 1.5x onto movies, an Anime4K pick followed the user into
live-action libraries, and a file-specific subtitle offset leaked onto the
next title.
Each of those settings now has a scope under Settings > Video Playback >
Remember Player Changes: don't save, everywhere (default, pre-existing
behavior), per library, or per show/movie. Player writes route through the
configured scope; playback start and in-place item changes resolve the
value for the current item, falling back to the global default. Items
without the needed identity (live TV placeholders, Jellyfin/Emby downloads
without a stamped library) keep the global behavior. Resolution consults
only the configured scope, so entries saved under a previous scope become
inert instead of shadowing the new one.

plex_pin_auth_flow's QR knobs, ProfileNameField's navigation params, MusicDetailHeader.wideArtworkSize, and _buildReorderableList's bool were never passed; DownloadType.manage was never constructed; MediaContextMenu.onTap was declared but never invoked — removed with its four card passes (each card's own gesture handlers stay); the pin dialog's obscure chain was always true and _PinKey.label's icon branches unreachable; libraries_screen._isInitialLoad was write-only; LiveTvActionsMixin loses dead findChannel (the generic parameter stays — required by the on-clause, the report was wrong); add_jellyfin's focus-map removal branch ran only against an empty map; the recommended tab's hub-key null fallback was dead behind _ensureHubKeys. media_card also loses its always-false seasonal-rank comparison from the CatalogRankScope removal.
TV state had two interchangeable entry points — PlatformDetector.isTV/isAppleTV and the raw TvDetectionService.*Sync accessors — with call sites split arbitrarily between them. App code now goes through the facade; the raw accessors document that they exist for the facade and tests.
persistAndBindConnection's addToManager/visibleServerId parameters and post-commit manager phase had no production caller (the Jellyfin flow defers runtime pickup to the profile binder) — the function is void now. A failed Plex account add threw a StateError that PlexPinAuthFlow re-rendered as a raw 'Bad state:' string beside the already-rendered inline error; the flow's normal return already stops the spinner, so the inline error is the single surface.

Shows whose Season 0 holds aftershow featurettes (e.g. House of the
Dragon "Inside the Episode") share air dates with the episodes they
accompany, so the air-date interleave from #1416 queued them between
regular episodes: playing S03E04 offered S00E76/S00E84 as up next.
Air date alone cannot separate canon Specials from featurettes, so
Specials placement is now a three-way preference, defaulting to
"follow server order":
- respectServer: Plex keeps its server-built /allLeaves queue (aired
order, Specials interleaved, as before); the Jellyfin queue now
preserves the /Shows/{id}/Episodes response order, which is
Jellyfin's native watch order — Specials placed only via explicit
AirsBefore* metadata per the server-wide DisplaySpecialsWithinSeasons
setting (the endpoint ignores SortBy except Random). Client-side
selections with no server order to respect (offline next/prev,
download "next N", offline OnDeck) fall back to Specials-last.
- airDate: the #1416 aired interleave on every surface.
- specialsLast: Specials strictly after the regular seasons (#1414);
Plex builds its show queue from /children.
The display-agnostic texture renderer restored by 9cdfe759 is deleted
again, this time for good: it is a second, SDR-only rendering stack
(isolated EGL context on Flutter's display plus EGL-image handoff) kept
alive solely to host sessions that cannot bring up the Wayland plane -
X11/XWayland or a failed plane bootstrap - and it was the source of the
native lifecycle and EGL state-churn fixes of the 9f2e0507 era. Linux
video now requires a Wayland compositor; a session that cannot host the
plane fails initialization with VIDEO_PLANE_UNSUPPORTED instead of
silently rendering through the second stack.
Reverts the restore commit's machinery: mpv_texture.cc/.h and
mpv_gpu_bootstrap.cc/.h deleted, the plugin's texture-registrar,
bootstrap, and waitForVideoReady paths removed, MpvPlayer's texture-mode
render-context API dropped, and the Dart-side renderMode setting, its
settings tile, translation keys, and the Player textureId member
withdrawn. The #1874 HDR diagnostic work is unaffected.
2.13.0 deleted the display-agnostic EGL/Flutter-texture renderer and made
the native Wayland plane the only path, hard-rejecting every session that
cannot host one - X11, XWayland (SteamOS Gaming Mode runs native apps
through Gamescope's XWayland), or a plane whose EGL bootstrap failed. This
restores the 2.11.0 texture path from git history as the fallback:
- Re-add mpv_texture.cc/.h and mpv_gpu_bootstrap.cc/.h (2.11.0 verbatim):
an FlTextureGL whose populate renders mpv into an offscreen FBO sampled
by Flutter via an EGL image.
- MpvPlayer gains the texture-mode render-context API (InitRenderContext,
HasRenderContext, GetEglDisplay/Context, Render(w,h,fbo)) beside the
plane's InitRenderContextForSurface/RenderToSurface. The isolated ES 2.0
context on Flutter's display and the X11 display param are exactly the
2.11.0 configuration hardware decode demonstrably worked in.
- initialize now tries the plane first and falls back to the texture path
when it cannot be brought up, returning the texture id (Dart's 2.11.0
'result is int' contract) with waitForVideoReady gating playback until
the GPU bootstrap settles. Both paths share one mpv core, so the
plane/texture decision precedes render-context creation.
- hdr-enabled/hdr-tone-mapping are intercepted in texture mode (no plane,
no HDR); the HDR toggle hides itself via isHDRSupported.
- New Linux setting 'Video rendering mode' (Automatic / Texture) forces
the fallback - the user-visible workaround for plane-only trouble and
for the hwdec interop regression, plus translations in all locales.
SDR only on the fallback, matching 2.11.0; the plane path is unchanged.
mpv 0.40's OPT_COLOR parser rejects anything but #RRGGBB/#AARRGGBB, so a
stored subtitle colour that does not parse made mpv refuse the write with
MPV_ERROR_PROPERTY_FORMAT — and the bare await in _runPlayerInitializationAttempt
turned that into the initialization error screen on every open. Subtitle
styling, volume-max, and the pre-open defaults (start/pause/sid) are now
sanitized (colours canonicalized to hex with fallback to the default) and
non-fatal, matching the existing hdr-enabled tolerance policy: a refused
preference write must never become "this session cannot play video".
The user mpv.conf editor is applied as runtime mpv_set_property writes, and
vo/gpu-context/gpu-api were not withheld, so a vo=gpu-next line re-created
mpv's output as a separate uncontrollable window and orphaned the embedded
render context. Add the VO family to the Linux-owned property set with a
key-aware skip log, a native reject for vo != libmpv on the video core (the
render API is OpenGL-only; gpu-next is windowed by construction), and a hint
in the mpv.conf editor explaining why, with translations across all locales.
A Portuguese user reported "Skip Intro" rendering in English on Android TV.
The locale files were not the problem - all 22 were structurally complete.
skip_marker_button.dart simply never imported strings.g.dart and assigned
'Skip Intro' / 'Skip Credits' / 'Next Episode' as plain literals. An audit of
lib/ found ~120 more sites in the same state, in four shapes that need
different fixes:
A literal in a file that never imported the i18n layer is the easy one -
skip_marker_button, performance_stats, track_label_builder and codec_utils all
render text with no `t` in the file at all. TrackLabelBuilder._compose now takes
a fallbackLabel builder instead of an English fallbackPrefix, so the caller
supplies t.audioTracks.track / t.videoControls.subtitleTrack and every unnamed
audio and subtitle row in the track menus is localized.
English reaching the user through an exception message is the widest one, and
it needs care: MediaServerException.message feeds both toString() - logs and
Sentry grouping - and verbatim UI display. Localizing it in place would make
bug-report logs follow the user's locale and split one Sentry issue into 22.
The MediaServer and Seerr families instead gain a nullable `display` alongside
the English `message`, and the six screens that print these errors read
`display ?? message`. PlaybackException keeps the opposite rule, because it
already carries a PlaybackFailureReason for logic and classifyPlaybackFailure
already builds it from t.messages: its stragglers are localized at the throw
site. That also removes the literal "Exception: " prefix Live TV users saw on
a tune failure, since PlaybackException.toString() returns the bare message.
Localized parts hand-concatenated with bare English are the shape no search for
Text('...') can find: '${t.common.pause} auto-scroll' on the home carousel,
'${day} at ${time}' on the Live TV schedule row, and an actor-screen count that
hand-rolled its plural as `n == 1 ? 'title' : 'titles'` - wrong for ru and pl
regardless of translation, now a real Slang plural.
Finally a literal assigned to provider state that a widget renders later:
DownloadProgress.errorMessage, and the four background_downloader notification
bodies, which sit inside a plugin config call where no widget-shaped search
reaches them.
Two things surfaced while converting. track_chapter_controls compared a track
label against 'Audio Track N' to swap in a localized version; once the builder
localized its own fallback that branch became unreachable, so it and the
orphaned _joinTrackLabel are gone. And discovery_view's PeerError fallback arm
looks like a leak but is not - its producers already localize, and a test says
so - so it stays as it is.
All 21 non-base locales are translated, including the 21 keys left empty by
earlier commits that were falling back to English. No locale has an empty value.
scripts/check_hardcoded_strings.py guards the three shapes a structural check
can see, and runs in ci_checks.sh after translation hygiene. Its first draft
passed its own tests while missing this very bug, because 'Skip Intro' is bound
to a local rather than handed to Text(); the name-bound rule that closes that
gap is restricted to phrase-shaped literals, or it cannot tell copy from the
identifiers this codebase binds constantly ('cast_row', 'auto', 'liveTv'). It
cannot see English inside a throw or assigned to a provider field - neither is
distinguishable from a log message without dataflow analysis - and the docstring
says so. label: and actionLabel: are deliberately unscanned: here they name a
diagnostic operation, and a check that is chronically red is a check that gets
switched off.
One commit rather than one per area: the keys, the 22 locale files and the
generated output are a single unit, and any partial split fails the repo's own
unused-key scan on the way through.

The Explore tab appears for every Plex-backed profile because the Plex
Discover catalog source connects implicitly, with no way to opt out
short of a Jellyfin-only profile. Add a Show Explore Tab switch to
Appearance > Navigation that hides the tab in the bottom navigation and
side rail. UI-only: catalog sources stay connected so watchlist
surfaces keep working while the tab is hidden.

Adds an "Anchor to Screen" toggle under Subtitle Styling (Android +
ExoPlayer only, default off). When enabled, the text SubtitleView is
sized to the full container instead of the letterboxed video rect, so
SRT/VTT/mov_text cues render in the black bars below widescreen video
and font size and the position setting become relative to the physical
screen height. Bitmap (PGS/VOB) and ASS/libass rendering are unchanged;
mpv already places plaintext subtitles in the margins by default.

Android TV's docked keyboard handles multiline editors natively, so
`automatic` no longer diverts them to the Flutter overlay there. Only
Apple TV keeps the overlay for multiline input — its modal fullscreen
system keyboard cannot edit multiline text. Surfaces that want the
overlay for editing ergonomics (mpv config, connection editor, dialog
text areas) already pin flutterOverlay explicitly.
Android TV returns to the platform keyboard for single-line fields; the
Flutter overlay stays for multiline and explicit call sites. The bugs
that forced the overlay (#1051, #1079) were an engine show/bind ordering
race, now repaired at the app level:
- MainActivity retries a soft-input show the engine dropped while the
FlutterView was not yet served (flutter/flutter#177360), rebinds the
IME key session once at first show, and consumes leaked D-pad keys
while the keyboard is visible (bounded restartInput budget) so focus
cannot wander behind a stuck keyboard.
- The platform text-input hint is activation-based, so gamepad pause and
the pre-IME D-pad intercept track a live session instead of mere field
focus.
- While a session is live with the keyboard away, Back closes it and is
consumed once, Select re-raises the keyboard, and arrows keep
caret-aware edge-escape navigation instead of dead-ending.
ExoPlayer's DefaultLoadControl was built with hard-coded durations picked from
one memory tier, so read-ahead stopped at 50s on any device reporting 2GB or
less free, with no way to raise it. On hardware where mpv cannot render at all
that ceiling is the whole buffer budget.
Playback Buffer offers Auto, Large and Extra Large. The durations are taken
from jellyfin-androidtv and jellyfin-android so the same words mean the same
thing across Jellyfin clients; Auto keeps the memory-tiered values that
shipped. Named tiers rather than a duration because a duration would be a
promise the load control cannot keep: prioritizeTimeOverSizeThresholds is
disabled, so targetBufferBytes stops the loader even below minBufferMs and the
byte cap binds first above roughly 23 Mbit/s.
The tier crosses the method channel as a string and resolves in the core,
where an unrecognised name falls back to Auto. LoadControlPolicy clamps the
resulting pair: media3 validates the ordering with Guava Preconditions, an
unconditional throw R8 does not elide, so a bad pair would be an
IllegalArgumentException out of player construction rather than a bad buffer.
The two play-start thresholds stay fixed even though the Jellyfin tiers move
them. BufferingStallPolicy.MIN_BUFFER_AHEAD_MS is a const derived from
BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS, so a runtime value there would make the
stall watchdog indict a player that is obeying its own load control.
That leaves the byte target as a second, often smaller ceiling, and nothing
surfaced either. The resolved values now reach getStats, and the overlay's
Buffer section gains a Cache Limit row reading "120s / 128MB" next to the
buffered-ahead duration, so a tier that appears to do nothing on a
high-bitrate file explains itself.

A head unit is a large screen sitting an arm's length further away than a phone,
and Plezy drew phone-sized controls on it: the primary button measured 8.3 mm
against the 64 dp a car needs. The whole surface is now scaled - 1.35 by default,
adjustable in Appearance - by giving the app a smaller logical viewport and
scaling the result back, so text, spacing and touch targets grow together instead
of a font size being nudged in isolation.
The scale sits above the messenger and the root Scaffold so snackbars and dialogs
are scaled too, and insets are divided back into the scaled space so a system bar
still reserves its physical size. A scaled surface is also a short one: the setup
screen's fixed offsets and the now-playing transport are laid out to survive it,
and a mistyped scale in a hand-edited settings file is clamped rather than
failing startup.
Connects MDBList through its OAuth device-code grant, registered as a
Device Code app so no client secret or redirect URI ships in the binary
and TV, mobile and desktop all use the same flow.
MDBList omits `verification_uri_complete`, but its device page seeds the
code field from a `user_code` query parameter and the sign-in redirect
preserves the query string, so the activation link is built locally and
the dialog's open button lands on a filled-in form instead of an empty
one. A server-supplied complete URL still wins if one ever appears.
Poll state is read from the response body rather than the status code:
`authorization_pending` and `slow_down` both arrive as HTTP 400, and a
missing grant answers 404 `device_not_found`.
Writes go out as real-time `/scrobble/*` reports plus `/sync/watched`
for the marks that never pass through the player, with ratings on
`/sync/ratings`. Matching uses IMDb and TMDb only — MDBList's id block
has no `tvdb` field, so a TVDB-only item is skipped rather than written
under an empty id block.
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.
Plezy is edge-to-edge on Android whether it asks to be or not: targetSdk is
36, Android 15 enforces edge-to-edge for apps targeting 35+, and Android 16
disables the windowOptOutEdgeToEdgeEnforcement escape hatch. The only
SystemUiMode.edgeToEdge call in the app fires on video-player exit, so on
API 35+ the window is edge-to-edge from the first frame and
MediaQuery.padding.bottom is a real ~48dp overlap under 3-button navigation.
MainScreen's phone layout hides that. It supplies a bottomNavigationBar and
never sets extendBody, so Flutter's Scaffold strips padding.bottom from the
body MediaQuery and every tab is already safe. Routes pushed on the profile
navigator are full-screen siblings of MainScreen with no bottom bar, so they
receive the untouched inset and nothing consumes it - the last settings card
and the final log lines render under the back, home, and recents buttons.
Three shared hosts own most of those routes, so the inset is consumed there:
FocusedScrollScaffold (25 screens, counting the SettingsPage wrapper) and
FocusableDetailScreenMixin.buildDetailScaffold (4) now append a trailing
SliverSystemBottomInset, and the four screens that build their own Scaffold
around a CustomScrollView append it directly.
The new widget codifies the convention this repository had already written
down but open-coded - insets baked into the scroll content rather than a
SafeArea around the scroll view - so content still paints under the bar while
the scroll extent grows enough to bring the last row above it. It reads
padding from its own context and collapses to zero height wherever the inset
is already zero: desktop, Android TV, tvOS via _AppleTvScale, and inside
MainScreen's tab bodies. No platform branching, and it stacks additively with
the music detail screens' existing mini-player spacers, which is correct
because the mini-player itself floats above the navigation bar on a pushed
route.
Scroll views that are not sliver lists take the inset in their own padding:
the companion remote's ListView, the auth screen's scroll container, and the
two SliverFillRemaining sign-in forms, whose children size themselves from
the extent remaining before them and so cannot be helped by a trailing
sliver. The logs empty state is left alone for the same reason inverted - it
already fills the viewport, and a trailing inset would only add scroll slack.
Verified on a Pixel 7 running Android 16 (API 36) with 3-button navigation:
Settings, Logs, and Video Playback all end clear of the bar.
close#1766
Since 2.10.0 the whole app sits behind one all-or-nothing initialization
gate, and that gate discarded the only evidence of its own failure. It
caught the error, logged nothing but `error.runtimeType`, rendered an
icon plus the word "Error" plus Retry, and never reported the error
because catching it kept the crash reporter from ever seeing it. There
is no log file on any platform, the buffer is in memory only, a
double-clicked Windows release build has no console, and the log viewer
lives in Settings, behind the gate that just failed. #1732 is the result:
a Windows 11 user whose app will not boot and who cannot produce a single
byte of diagnostic detail.
The gate now names its phases. Each step is wrapped so a throw carries
the phase it came from, replacing a `Future.wait` that discarded every
error but the first and could not attribute it to any of four concurrent
steps. The failure screen renders the phase, the exception type, the
message and an expandable stack, plus copy and upload actions that reuse
the existing log-relay flow. The record is persisted next to the database
so the next successful launch can surface it in Settings > Logs, and it
is reported to the crash reporter explicitly.
Only preferences and the database still gate the launch. Window chrome,
locale, crash-reporting init, TV/performance detection, the image-cache
budget and download storage are best-effort and time-bounded, so a
stalled platform thread degrades instead of holding the splash forever.
Sentry no longer receives the startup work as its `appRunner`: that made
a startup failure indistinguishable from a Sentry failure, and the guard
would then have re-run migrations and the database open a second time.
The two remaining fatal steps become recoverable. Preference reads
tolerate a value whose stored type no longer matches, dropping the key
and defaulting instead of failing the boot. A store that cannot be parsed
is detected before either desktop plugin backend can memoise it, which is
what makes an in-process repair possible at all. Repair is never
automatic: it states what it will cost, salvages the credential-vault key
and every tracker and Seerr session it can validate out of the damaged
bytes, reseeds them, and moves the original aside rather than deleting
it. Servers and profiles survive a salvaged key because their tokens are
ciphertext in the database; tracker and Seerr sessions are plaintext
preference entries, so the copy says they may still need reconnecting.
Nothing derived from the store reaches a diagnostic. `FormatException`
prints an excerpt of whatever it failed to parse, and during startup that
document holds the vault key, refresh tokens and session cookies while
the redaction manager still has nothing registered, so the wrapper keeps
only the cause's type and offset and the record is an allowlist of
already-redacted fields. The quarantined copy is labelled as containing
credentials, is never offered for upload, and can be deleted from the
dialog.
Also self-heals orphaned WAL/SHM sidecars on desktop rather than only
tvOS, makes every `createTable` migration step idempotent, keeps MSVC
link by-products out of the Windows bundle, and asserts bundle contents
in CI.
Refs #1732
Apple TV single-line fields moved to the engine's UITextField proxy in
2.10.0 (71735354), which made three focus behaviours user-visible.
Submitting re-attached the input connection. EditableText schedules a
restart when a submit action fires with a non-null onSubmitted, and that
microtask runs before the setState flipping readOnly, so the field
re-showed a keyboard the form had just dismissed. The native path now
withholds onSubmitted from EditableText and invokes it from the host,
independently of onEditingComplete as _finalizeEditing does.
Auto-open fired on every focus entry, so D-pad traversal of a multi-field
form raised and dismissed the modal system keyboard on each step.
TvTextInputAutoOpenBehavior gains onFirstFocus, and the new `automatic`
default resolves to it on Apple TV: arriving at a field opens it once,
returning to it does not. Android TV keeps its docked-IME auto-open, and
explicit modes stay literal on both. The autofocused Jellyfin and Seerr
URL fields keep an explicit exception so entering the screen still does
not bury the form (#1217).
EditableText.connectionClosed unfocuses the field outright, so a UIKit
keyboard dismissal left nothing focused at all. The host takes focus back,
keyed on identity with the field's own enclosing scope so a dialog or
route claiming focus meanwhile is left alone.
close#1728
The Store's unpackaged EXE path would require Authenticode-signing the
installer and every PE file inside it. MSIX submissions are re-signed by the
Store instead, so this route needs no code-signing certificate. build-msix.ps1
mirrors build-installer.ps1 and consumes the same per-architecture build
artifacts, leaving the installer, portable archives and WinSparkle appcast
untouched.
One template generates the manifest for both architectures, carrying the
identity reserved in Partner Center. check_windows_msix.py recomputes the
package family name from the publisher DN, so a mistyped identity fails CI
rather than a submission, and it parses the script rather than running it
because root CI is Linux. Qualified logo assets are indexed into
resources.pri; without the altform-unplated variants the shell draws the
taskbar icon on an accent-coloured plate.
PlatformDetector.isPackagedInstall gates the in-app updater and the Liberapay
tile, which the read-only package directory and Store commerce policy
respectively rule out. Gating at runtime keeps one Windows build feeding both
the installer and the Store package.
Trakt was the one service outside the tracker abstraction. TraktScrobbleService
re-implemented the whole playback lifecycle beside TrackerCoordinator, and
TraktSyncService pushed watched state from its own WatchStateNotifier
subscription, so the player called two objects at every lifecycle point and one
watch could be written twice. TraktTracker now implements RealtimeScrobbleTracker
like Simkl; the duplicated player call sites collapse to one each, and Trakt
shares the coordinator's ID resolver instead of re-fetching show ids every
episode.
Capabilities are split so a tracker declares what it is rather than being
special-cased: ScrobblePolicy carries each service's own resend/seek rules,
EpisodeHistoryTracker names the remote row a per-item history write targets, and
SeriesProgressTracker covers one-counter-per-series services. Writes from all
four trackers go through a shared TrackerWriteQueue, generalised from the
Trakt-only queue, with the legacy Trakt payload migrated on load. Trakt becomes
the fourth TrackersProvider slot and TraktAccountProvider is deleted, so one
object owns the active session per profile.
Two failure paths found while consolidating are fixed here too.
The queue's retries only ran on profile bind, connect and app foreground, so a
network blip mid-session left queued watches waiting for the next foreground.
OfflineModeProvider now notifies on connectivity changes, not just offline-state
or WiFi-flag changes, and main.dart flushes the queue when the network returns.
The queue also counted every failure toward the five attempts that permanently
drop an item, so a rate limit or a service having a bad hour could discard a
pending watch - the loss the queue exists to prevent. Only an answer about the
write itself now spends an attempt: 4xx counts, while rate limits, 5xx,
recoverable token-refresh failures and requests that never arrived do not. A
back-off answer also defers that service for the rest of the flush, so a queue
holding many rows does not fire all of them at a service that just asked for
quiet.
With the new playback setting enabled, episode advance carries no audio or
subtitle preference at all, so both resolve from the streams selected on
the server for each individual episode. This serves setups that curate
selections server-side (e.g. Plex Auto Languages) and is independent of
"Remember track selections", which keeps gating only the write-back of
manual changes.
close#1717
Every artwork budget in the image pipeline was tuned for 1080p surfaces:
the transcode request clamp (1920x1080), the per-type decode caps
(poster 720x1080, thumb 960x540, heroLogo 1000x500, ...) and the TV
image-cache bytes. Those numbers are exact on phones and on the many TV
boxes that composite the app at 1080p, but a TV compositing at 4K
renders every capped image below its slot and GPU-upscales the result:
hero backdrops by 2x, hero logos by ~1.8x, wide episode thumbs by ~1.3x,
shelf posters by ~1.13x - the softness reported against the official
Plex client in #1697, and the class #860's min-2x-DPR fix could not
reach.
DevicePerformance now latches a display budget factor - the display's
shortest physical axis over 1080, capped at 2x - whenever the image
cache budget is applied (startup, post-mount, effects-setting changes).
The transcode clamp, the full-tier decode caps and the TV cache bytes
all scale by it, so a 4K surface fetches and decodes 4K backdrops and
proportionally larger cards. The reduced tier stays pinned to 1.0, and
sub-2.5GiB hardware holds the factor at 1.5 so full-budget 4K art
(~33MB per decode) cannot starve mid-RAM boxes; latching once per
session keeps transcode URLs - and with them the disk cache keys -
stable across rotation and rebuilds.
Whether a given TV composites at 1080p or 4K decides whether any of
this can help, and logs never recorded it: the startup banner and the
log-upload header now carry a display line (physical, logical, DPR,
latched budget) so uploaded logs answer that question directly.
The two pre-existing Windows-host test failures (automotive auto-PiP
gate, backdrop temp-dir teardown lock) reproduce unchanged on the base
commit.
Since real device names started reaching the header, an accented one
made login impossible: dart:io refuses header values above 0x7F, and
CFNetwork puts the raw code unit on the wire as a Latin-1 byte, which
Kestrel rejects as a malformed request with 400 before Jellyfin routes
POST /Users/AuthenticateByName.
Encode every field the way the official Jellyfin SDK does; the server
already reverses it with WebUtility.UrlDecode, so the wire value stays
pure ASCII while the device list shows the real name. Quotes, commas
and `=` no longer need stripping either. sanitizeHeaderValue, which
still guards the Plex headers, now folds Latin letters to their base
form instead of emitting bytes no transport accepts.
close#1685
Detection now runs off the UI isolate and covers every platform where
the answer can be trusted.
Availability was a plain platform check, so Linux always listed VLC, mpv
and Celluloid, macOS always listed VLC and IINA, and Windows always
listed VLC and PotPlayer whether or not any of them existed. Each player
now has a detector that asks exactly the question its launcher asks:
`sh -c 'command -v'` for PATH launches so the kernel performs the
executable check, NSWorkspace/Launch Services for `open -a`, `where.exe`
plus the concrete install paths for Windows VLC, and the registered URL
handler for PotPlayer and the iOS players.
Detection is asynchronous and memoised behind KnownPlayers.probe rather
than a Process.runSync in a static initialiser, which forked three
shells on the UI isolate during ExternalPlayerScreen.build. It is
prewarmed from startup, fails open when a probe throws, and keeps the
selected player listed when a detector misses it so a false negative
cannot leave the list with nothing selected.
iOS and tvOS gained LSApplicationQueriesSchemes entries for vlc and
infuse. Without them canOpenURL returns false for both schemes, so
_launchUrlScheme was already refusing to hand off to either player.
Android keeps the platform check: package visibility needs native
declarations, and a wrong answer there hides a working player.
