A player whose predecessor had not released the shared native channel
within three seconds skipped its own native dispose and chained its
release onto that predecessor. If the predecessor's teardown never
completed - one hung 4K session was enough - every later player waited
on the chain, failed to initialize, and playback stayed broken with
"Playback could not be started" until the app was killed.
Initialize and dispose now carry the creating instance's token. The
Android plugins remember which token created the current core and
acknowledge a dispose from any other token without touching the core,
so a dispose that lost the ownership race is provably stale and safe to
send. With that guard, a timed-out ownership wait force-disposes
instead of skipping, settles its release unchained, and frees the
channel for the next session; a dispose watchdog answers Dart even if
a native teardown hangs, leaking that one core instead of wedging all
future playback. Commands wait eight seconds (was three) so a slow but
healthy teardown delays the next session instead of failing it.
Verified on a Shield Pro: 38 back-to-back session races at 0.8-2.2s
gaps with zero failures and balanced teardowns, and a deep-link-over-
playback collision whose stale dispose is ignored, after which Back
returns to the still-playing session and Retry starts the new one.
Apple and desktop handlers ignore the token and keep the historical
skip semantics until they gain the guard.
With video on the MediaCodec plane, real bitstream passthrough, media3
demuxing, and the GL fallback ladder in place, mpv measures at parity
or better than ExoPlayer on every device class tested (Tegra, Mali,
Amlogic armv7, Adreno; API 28-36; phone, TV, and foldable), including
the two historical Android mpv failure modes: low-end TV playback and
Hi10P.
Installs that never chose a backend move to mpv; a stored ExoPlayer
choice is preserved, and the Player Backend toggle stays user-visible
as the escape hatch. The automatic ExoPlayer-to-mpv runtime fallback
is unchanged.
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.

mpv's ao_audiotrack hardcoded stereo IEC61937 frames, which cannot
carry TrueHD MAT or DTS-HD MA 8-channel bursts, and the app fed
audio-spdif an empty list in self-defense because mpv
force-passthroughs every codec named there with no decode fallback.
The mpv path therefore decoded everything, and passthrough had to be
enabled by hand on every install.
The Kotlin audio route probe (AudioOutputPolicy) now feeds mpv a
per-route audio-spdif list, the fork's multichannel IEC61937 patch
(pinned libmpv v1.1.3) provides the burst geometry, and E-AC3, TrueHD
and DTS-HD MA bitstream on the mpv path. Android TV installs with no
stored preference default to passthrough on, on both backends; an
explicit user choice is preserved.
Verified by route probing and mpv logs on Shield and Box R; no AVR was
in the loop, so receiver-side decode is unconfirmed.
Software-decoded HDR always collapsed to SDR on Android: the EGL
window surface carried no colorspace, so PQ/HLG content that fell back
to software decode rendered through an SDR surface, and Android was
excluded from the hdr-enabled path outright.
The GL vo now requests a BT2020-PQ window surface (fork patch, pinned
libmpv v1.1.3) and Android joins the hdr-enabled path, so software
decode keeps HDR scanout and tone mapping happens only when the
display genuinely cannot show HDR.
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
MPEG-TS segments cannot carry AV1, so a Jellyfin server with an AV1
hardware encoder (Intel Arc and similar) could never pick AV1 as the
transcode output no matter what the codec list advertised. Switch the
video TranscodingProfile container from ts to mp4, matching
jellyfin-web's fMP4 HLS behavior; mpv consumes fMP4 HLS on every
platform and the Plex VOD target has shipped it since issue #1859.
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.
Turning what a user typed into URLs worth probing lived inside
JellyfinEndpointDiscovery, next to a private copy of the scheme-detection
regex that url_utils already had. A second backend needs the same rules
with a different default port, and the existing copy carried two latent
defects: input with no host came back unchanged, so a candidate that can
never resolve went to the prober, and a query string survived into the
base URL that request paths are appended to.
expandBaseUrlCandidates takes the ordered guesses a backend wants — a
scheme plus the port to try when the user typed none — and owns the rest.
A typed port beats a guessed one, so host:8096 collapses to one candidate
per scheme and the same guess list covers both bare hosts and hosts with
ports. Candidates are built field by field rather than through
Uri.replace, whose null query means "keep mine", so query and fragment
are dropped for real. Blank input and input with no host expand to
nothing.
JellyfinEndpointDiscovery passes its existing order, so its probe and
persistence behaviour is unchanged, and hasUrlScheme replaces the regex
copy.
Playing a downloaded movie or episode failed outright once the storage
holding it was gone — an SD card ejected, a USB volume unplugged, the
files deleted from outside the app (issue #2101). The item still played
fine from the server, but Plezy never tried: it committed to the local
copy and surfaced mpv's open failure.
Resolution already refused a missing local copy and let the caller
stream instead, but only for filesystem paths. SAF `content://` URIs
skipped the check on the premise that they are always playable as
written. They are not: an unmounted volume answers
`FileNotFoundException: No root for <volume>`, and a revoked grant is
just as dead, while the row still reads `completed`.
Probe the stored document through SAF before preferring it, so an
unreachable copy resolves to nothing and every consumer degrades the
way a missing file already did — the player streams, and both
external-player entry points launch against the server instead of a
dead URI.

Siri Remote navigation felt sluggish and then over-sensitive next to
native tvOS apps (issue #2006): swipes were priced at a fixed travel
per step, a single flick could glide into a second focus step, hard
lifts coasted several extrapolated steps, and rail scrolls snapped in
65-250ms where native glides.
Retuned the whole path against two hardware instrumentation passes on
an Apple TV 4K: committed-move telemetry through an experimental
UIFocusItem bridge (branch feat/tvos-native-focus-bridge), then a
dedicated native probe app logging every touch sample, pan velocity,
engine hint, focus step, and scroll tick across 101 swipe sessions on
160/230/300pt tiles. What the data showed, now encoded:
- step pricing follows geometry: one step costs the focused item's
extent along the swipe axis plus ~155pt (measured 314/391/410pt on
160/230/300pt tiles), not a fixed distance. Thresholds derive per
axis from the primary focus rect, normalized so a wide-flat control
steps vertically once the finger covers its height. Locked-focus
rows (hub rows, the TV browse rail) vend their selected card's rect
through the new LockedFocusRowNode so the row-wide focus node's
screen-sized rect never prices the step. Scopes, the player's
catch-all surfaces, and unbuilt cards fall back to a fixed 400pt.
- a lift never coasts more than one step: sessions with lift
velocities up to ~11400pt/s never produced a second coast step. The
glide is gated on a sustained drag (two consecutive same-direction
steps), cancelled by reversal pivots and new touches, so a discrete
flick moves exactly one item.
- the native 'inertia' feel is the scroll animation, not focus
physics: the engine's scrollable containers settle over ~450-900ms
of ease-out. TV rail and hub-row navigation scrolls now retarget a
500ms easeOutCubic animation per step, so drags and hold-repeats
chain into one continuous glide that catches up on release.
With "Ask for profile on app open" enabled, every screen-off or app
switch on a phone re-pushed the profile picker and PIN on resume, burying
a companion-remote session that survives backgrounding since the
reconnect cycle was made lifecycle-aware. Suppress the resume prompt
while a companion session is live, mirroring the active-playback
exemption — the session already belongs to the profile that started it.

Non-English users saw English text in a dozen places and blank labels in
sixteen more.
The English came from sites that produce their copy away from the widget
that renders it, which is what the structural hardcoded-string check
cannot see: picture-in-picture refused with a raw literal instead of the
pipErrors.notSupported key that already existed; the two Jellyfin/Emby
auth throws missing display: rendered their developer message on the
add-server form; ServerParsingException.toString() fed its English into
the localized "Failed to load servers" wrapper; Watch Together
interpolated the whole PeerError, so a failed create read "Failed to
create session: PeerError(PeerErrorType.timeout): Timed out creating
session" and join printed its prefix twice; the hub and playlist
continuation footers rendered exception.toString(); shader rows showed an
English title over an already translated subtitle; the player queue fell
back to the raw Dart enum name; a Plex home user with no title showed
"Unknown"; a failed player start showed "Exception: Failed to initialize
player"; and the tvOS top-shelf header was hardcoded in an extension that
has no Flutter engine.
The blanks came from three recent features that added English keys
without translations. clean_translations.py filled all 21 siblings with
empty strings, so the Android TV resolution switch, every Jellyfin/Emby
recording-rule field, the demuxer row, the Companion Remote address
caption and the Seerr blocklist pill rendered nothing at all.
Two fixes are structural rather than key swaps. ContinuationStatusSliver
now takes an errorContext and calls a new non-logging
localizedLoadErrorText, so no future throw can leak through it. lib/mpv
stays free of user-facing copy: it raises a PlayerInitializationException
sentinel and a PlayerError.playerInitFailed cause tag that the player
screen resolves to localized text. The tvOS section title travels in the
shelf payload, additively, so an older cache still renders.
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.

In-player subtitle search always ended with "Subtitle downloaded, but it
could not be selected": the apply flow polls getVideoPlaybackData for the
new external stream, but the fresh-cache-first fast path (be9197ed) served
the pre-download /library/metadata row for every iteration — playback
start leaves a fresh row, and the first network poll re-stamps it, so the
new stream was never observed and the flow timed out.
Add forceRefresh to PlexClient.getVideoPlaybackData (mirroring
getPlaybackExtras) and pass it from the download poll loop. The forced
fetch still rewrites the cache row, so the subsequent source switch sees
the new track.
On Linux the Home page, a library's Recommended tab and movie/show detail
pages could not be scrolled at all, while Browse, Collections, Playlists,
search, downloads and settings scrolled normally. Those three screens are
exactly the ones whose viewport is covered by horizontal hub rows.
A wheel, trackball, trackpoint or button-scroll event expresses one-axis
intent, but the host reports both axes in the same event: on Linux only
touchpad-sourced scrolling becomes a pan/zoom sequence that resolves in the
gesture arena, and everything else arrives as one PointerScrollEvent
carrying whatever dx the device produced. A Scrollable claims a scroll
signal as soon as the delta along its own axis is non-zero, and the deepest
claimant wins the PointerSignalResolver, so a tenth of a pixel of dx handed
the whole event to the horizontal row and the page behind it never moved.
Collapse a scroll signal onto its dominant axis in the binding, before hit
testing - the last point where the delta can still be corrected, because a
Scrollable has already registered with the resolver by the time it sees the
event. Pan/zoom events are left alone, so trackpad panning keeps both axes,
and a horizontal wheel or tilt still scrolls the row it points at.
close#2081
In TV mode the sidebar menu floated unreadably on top of the home rows,
the artwork and the settings list — two overlapping sets of text with no
panel behind either.
The rail's surface is transparent on TV so the full-bleed backdrop
continues behind a docked rail, which is safe because the shell displaces
content around it. 2.16.0 turned hover/touch expansion into an M3E modal
panel that overlays content at the collapsed offset instead of pushing
it, so there the rail painted nothing and content showed straight
through the menu.
Keep the transparency rule for every docked shape and paint the surface
whenever the rail floats, reusing the predicate that already gates the
overlay corner radius and edge shadow. The fade now shares the width
morph's duration and curve, so a shorter fade cannot strand a fully
grown, fully transparent panel over the content mid-collapse.
Reproducing needs Force TV mode plus a pointer, which is why this
surfaced on a SteamOS box driving a TV and never on Android TV's D-pad
path.

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.

Tapping a discovered desktop in the phone's companion remote did nothing:
the device list emptied to "No devices found on your network" and no
connection was ever made. Manual IP:port entry silently did nothing too.
A host advertises every local IPv4 address, so a PC with virtual adapters
(WSL, Hyper-V) broadcasts addresses the phone cannot route to. The client
races them all, and cleanup of the losing candidates awaited
`sink.close()` on channels that never connected. That future never
completes in web_socket_channel: the close future waits on the local
stream's listener, which is only attached on the connect-success path. So
the race never finished, the winner was never joined, and the flow just
stopped with no error.
Cleanup now tracks whether a candidate ever connected: unconnected probes
get a deferred close armed on `ready` settling instead of a blocking
await, and they skip the terminal drain since they hold no host admission
slot. The managed join gets a real connect timeout that surfaces as a
typed timeout error, and disconnect during a pending connect closes the
socket once the connect settles rather than blocking on it.
Two paper cuts around the same flow: a failed attempt now restarts
discovery instead of stranding the cleared list on "No devices found",
and the desktop's server card shows its listen addresses so manual entry
is not guesswork.

A quoted value in the mpv.conf settings screen, copied verbatim from a
real mpv.conf (sub-font = 'NetflixSans-Bold'), reached mpv_set_property
with the quotes included: a string property silently selected a
nonexistent font family and fell back to the bundled font, and a
numeric property failed mpv's parse and was only logged. Either way the
line did nothing. mpv's own config-file parser strips one pair of
matching quotes around the whole value; parseMpvConfigText now does the
same before the startup pass applies the entries.

On a 32-bit Amlogic TV box, 57% of UI frames while moving focus along a rail
missed the 16.68 ms budget, and the median frame was already over it at 20.7 ms.
The GPU was idle throughout (raster p90 9.1 ms, zero frames over budget) -- all
of it was main-isolate work, split roughly evenly between layout and semantics.
Five separate causes, all measured:
- The horizontal rail used `itemExtentBuilder`, so `RenderSliverVariedExtentList`
walked every preceding index on each realized child, in every layout pass, and
re-resolved the trailing slot inside the closure. Pinning the trailing cell to
the card extent makes the list uniform, which restores O(1) offset, index and
max-extent math.
- The sidebar-expand tween wrapped the whole shell with a `LayoutBuilder` inside
its builder, so ~15 ticks per focus flip rebuilt `SideNavigationRail` -- and its
non-virtualized child list -- during the layout phase. The tween now wraps only
the content `Positioned`, matching `SideNavigationBleedBuilder`.
- Each nav item crossfaded through two `Opacity` subtrees, i.e. 14-18 offscreen
save layers per frame for the whole 250 ms morph. It now fades colour alpha on
the leaf, the same substitution `AnimatedDimScrim` already documents.
- `HorizontalScrollWithArrows` kept a scroll listener on platforms where its arrow
chrome is compiled out, so crossing either scroll boundary `setState`d a whole
rail row of cards. Two full-row rebuild storms per traversal, for arrows that
cannot appear.
- The rail's semantic proxy rebuilt its label and six closures on every
`_RailFocusModel` notification, including vertical-scroll flips.
Also: one merged listener per `SettingsBuilder` instead of six, and the media card
semantic label is cached rather than rebuilt and then discarded by the rail's
`ExcludeSemantics`.
Measured on the device, median of three runs: frames over budget 120/212 -> 32/246,
total UI-thread work 4067 ms -> 1845 ms, layout p90 18.2 -> 8.1 ms, build p90
7.95 -> 2.42 ms. The sidebar scenario went from 121/148 frames over budget to
32/184.
Two cold-start findings from the same pass. They share a call site in
`MainScreen`'s post-frame block, so they land together.
## Cronet was 33% of time-to-interactive
`createPlatformClient()` built the shared `CronetEngine` inline, so whichever
consumer happened to create the first HTTP client paid for it — and that landed
between `database_ready` and `credentials_loaded`, i.e. squarely on the path to
the first usable screen.
Measured on the Amlogic SC2 box, phase marks relative to `dart_main`, by
temporarily forcing the existing `_cronetBroken` fallback so no engine is ever
built:
| phase | engine built inline | engine never built |
|---|---|---|
| database_ready | +455 | +456 |
| credentials_loaded | +1171 | +703 |
| binding_settled | +1331 | +827 |
| main_screen | +1394 | +932 |
So ~462 ms, fully serial. Logcat shows where it goes: `DynamiteModule
loadModule2NoCrashUtils` then `HttpFlagsLoader` reading
`com.google.android.gms/app_httpflags/flags.binarypb`. The cause is provider
*enumeration*, not selection — `CronetEngine.Builder(Context)` calls
`isEnabled()` on every registered provider, and `PlayServicesCronetProvider`
answers that by installing the Play services Dynamite module. `play-services-cronet`
arrives transitively through `media3-datasource-cronet`, and `package:cronet_http`
offers no way to choose a provider, so the only lever available in Dart is *when*
the cost is paid.
Android's `createPlatformClient()` now returns a client that resolves its
delegate per request: the tuned IOClient that already backstops a broken Cronet
until the shared engine exists, Cronet afterwards. Per-request matters — a
`MediaServerHttpClient` builds its client in a constructor initializer and lives
for the process, so deciding once at construction would have pinned primary
media-server traffic to HTTP/1.1 forever, which is a silent steady-state
regression rather than a fix. `warmUpPlatformHttpClient()` then builds the engine
from `MainScreen`'s post-frame block.
Result: `main_screen` +1394 -> +915 ms, and logcat carries both client lines
(`IOClient (Android fallback)` then `CronetClient`), proving the swap. The build
now runs from +1023 to +1419, entirely after the first screen, and produces no
Choreographer or Davey report — the UI is static waiting on hub content there, so
there are no frames to drop.
## Plex Home refresh raced the offline decision
`PlexHomeService.start()` conflated disk hydration with going live: it decoded
the cached `plex_home_users_*` entries *and* subscribed to connection changes,
installed a refresh timer and fired `_refreshAll()`. It was invoked straight from
a provider `create:`, so on a box with no network — or the flaky 2.4 GHz Wi-Fi
these devices typically have — it started requests that would time out during the
exact window the startup gate needs. Its immediate neighbour
`ActiveProfileBinder` is explicitly not auto-started for this reason and says so
in a comment; the same argument applied here and had simply not been followed.
`start()` is now the live/network entry point and `hydrate()` is the disk-only
half, coalesced and lifecycle-guarded like `start()` already was. The provider
`create:` hydrates; `_reloadSnapshot` and `reloadFromStorage` hydrate; the borrow
picker hydrates, because it reads `current` immediately and is reachable while
offline. Only `MainScreen` goes live, gated on `!_isOffline`, with
`_handleOfflineStatusChanged` picking it up if the session later regains network —
otherwise an airplane-mode launch would never refresh Plex Home again.
Hydration still `_emit()`s, so `stream`'s replay contract holds even when the
network side never starts, which is what keeps a late listener behind a
`combineLatest` off a permanent spinner.
Nothing sat between the full-screen `RasterizedGradient` scrim and the
position-driven leaves, so `markNeedsPaint` from the timeline slider walked past
the gradient and re-rasterized the entire chrome -- top bar, button row,
timestamps, timeline -- on every 250 ms position tick. That also partly defeated
`RasterizedGradient`, which exists because Skia gradients cost ~10 ms per
full-screen pass on this GPU class.
Around that, four things drove root `setState` calls that only needed to change a
leaf:
- Held D-pad seek called a root `setState` per key repeat, even when the readout
was already visible in the same direction and only the accumulated seconds had
changed. The seek amount now flows through a `ValueNotifier` that
`DoubleTapFeedback` reads, so a burst updates one `Text`.
- `DoubleTapFeedback`'s drift chevron ran `..repeat()` with no stop condition, and
kept ticking at 60 Hz for the ~300 ms the readout spends at zero opacity after
every burst. The controller is now gated on visibility.
- The auto-skip countdown ran a 5 Hz timer that root-`setState`d the controls tree
for the whole intro/credits window, to animate one progress ring.
- The play-next and still-watching countdowns root-`setState`d the player screen
once a second, which re-created `PlexVideoControls` with its ~50 props and
rebuilt the entire chrome to change one digit. Prompt open/close deliberately
stays on the state path, because `playNextFocusNode` is threaded through those
props and D-pad focus depends on it.
Two of the four position subscribers existed only to recompute pointer-hover
tooltips that a D-pad viewer never sees, rebuilding a button subtree 4x/s and
rescanning the chapter list each time; the "ends at" readout reformatted a string
4x/s for a value that changes once a minute. All three now dedupe.
Finally, the buffer path did two sequential `copyWith` calls on a 15-field
`PlayerState` and handed `BufferRangePainter` a freshly allocated list every tick.
`List` has no value equality, so `shouldRepaint` was unconditionally true.
Measured on device during playback with the chrome raised: 6 of 344 UI frames over
budget, p50 4.39 ms, layout p90 1.09 ms. During a held D-pad seek -- the worst
frame-time window on the TV path, because the readout and the decoder flush land in
the same frames -- 1 of 354 frames over budget, p50 4.28 ms, zero raster frames over
budget.
Cold start on the target TV box reaches its first frame 21 ms after `dart_main`,
so nothing Dart-side gates the splash. Everything below is on the path to the
first *useful* frame, which is a strictly serial chain and where the viewer
actually waits.
- `monoTheme` is a pure function of two bools that builds a full `ColorScheme`, an
applied-and-copied 15-style `TextTheme`, ~14 sub-themes and then clones the whole
`ThemeData` again. It was rebuilt five times per cold start, two of them before
`runApp`, and twice more per app-shell rebuild. It is memoized now, keyed by
palette plus `TargetPlatform` -- the platform matters because `ThemeData()`
derives tap target size, visual density and typography from
`defaultTargetPlatform`, so a palette-only key would be wrong under a debug or
test platform override.
- `initializeDateFormatting` ignores its locale argument and builds CLDR symbols
and patterns for all 121 locales synchronously. It blocked the gate ahead of the
database open for data that only content screens use.
- `DownloadStorageService.initialize` ended in a `path_provider` round trip plus
mkdir at the tail of the gate, contradicting the comment above it that already
explained offline artwork is not a launch requirement.
- `recoverInterruptedDownloads()` and `TrackerCoordinator.initialize()` ran from
`initState` of the widget whose first build produces the first app frame, and
the RSS watchdog installed a periodic timer there whose first useful sample is
15 s away regardless.
- `CredentialVault` decrypted every token with pure-Dart AES-GCM on the main
isolate, uncached, on every registry read and on every Drift re-emit -- and the
binder writes tokens during the startup sweep, so writes re-triggered reads.
Decryption is memoized by ciphertext, with `invalidateCache()` wired into the
preference-store repair path so a repaired install cannot serve stale plaintext.
- `reloadFromStorage` now coalesces in-flight callers. The two serial awaits around
the legacy migration are deliberately not merged; only genuinely concurrent
callers share a snapshot.
- `_sameConnections` ran two `jsonEncode` calls per connection on every Drift emit
purely to compare, allocating two maps and two strings each time.
- The splash rendered one `CircularProgressIndicator` per pending server on top of
the aggregate one, so N+1 tickers scheduled a frame every vsync for the whole of
`awaitBindingSettle` -- competing with the startup work they were reporting on.
Measured on device in a settled dexopt state: time to `main_screen` 1495 -> 1400 ms,
`credentials_loaded` 1238 -> 1128 ms, `database_ready` 501 -> 443 ms. First frame is
unchanged at ~18 ms, as expected.
The image pipeline funnels through `MediaImageHelper.serverArtworkProvider`, which
sizes the request, bounds the decode and namespaces the disk key. Five places
escaped that funnel, and on the reduced tier they compete for a 64 MiB image cache.
- Jellyfin trickplay prefetch built a bare `CachedNetworkImageProvider` and called
`resolve()` on it, fully decoding a sprite sheet -- roughly 22 MiB of RGBA for a
10x10 grid of 320-wide tiles. None of it was ever painted: the render path wraps
the same provider in `ResizeImage`, so it decodes again under a different cache
key. The comment already said the intent was only to warm the disk cache, so it
now does exactly that through the cache manager and resolves no image stream.
- `CyclingMediaBackdrop` re-fetched and re-decoded a full-screen backdrop every
10 s forever, with no `DevicePerformance` term in `_canRotate` even though its
own fade duration is tier-gated. At the reduced tier's 1280x720 art cap that is
3.52 MiB per rotation, ~7 MiB live across the crossfade, churning while the
viewer sits still and evicting the rail posters behind it. The fade is already
zero-duration there, so the rotation bought variety and nothing else.
- Catalog detail passed `item.posterUrl`/`backdropUrl` with no client, which
`getOptimizedImageUrl` deliberately returns unmodified -- so a 40x60 slot pulled
a 600x900 TMDB asset and a 320-tall backdrop pulled 1920x800. `posterFor`/
`backdropFor` already existed for this; the sites now use them.
- The season strip, the Live TV programme sheet and the profile avatar built
`CachedNetworkImage` directly, keeping the sized request but losing the
`plex_optimized_<sha1>` disk key, so the same artwork was cached twice and
re-downloaded on detail open. The season strip also discarded its height bound.
Sources without published variants (Trakt, AniList, MAL, MDBList) still fall back
to the base URL.
The detail hero builds its own pill around InlineRatingBadges since the
hero-chip rework, leaving MediaRatingBadgeGroup without a caller and the
unused-code check red. Remove it and inline the style helper its removal
left with one call site.
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 three browse chips opened bottom sheets on every form factor. On
desktop platforms they now anchor dropdown popups to the chip: grouping
is a radio menu, sort shows the direction on the active field
(re-selecting toggles it) plus Clear, and filters use a two-level menu
with per-category values and an All row to clear one category. Phones
and TV keep the existing sheets.
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 Active badge and connection chips used opaque primaryContainer /
surfaceContainerHighest - both resolve to the card surface color in the
mono scheme, so they punched dark holes in the focused tile's background
highlight, and boxed pills fight that fill however they are tinted. The
Active badge becomes a muted check icon + label next to the name, and
connection chips become plain muted icon + text entries, matching the
app's other meta rows.
Switching to the Explore tab hands focus to the first hub, and
HubSection unconditionally ran Scrollable.ensureVisible, scrolling the
app bar and search field off-screen in touch mode. The scroll is now
gated on keyboard/D-pad input mode, mirroring FocusableWrapper's
autoScroll.
The hero metadata strip wrapped to a second run, leaving the Rate chip
alone on its own line (or clipping it away on short heroes). The strip
now measures chips and sheds them by usefulness - scores pill first,
then quality labels, edition, certification, runtime - never the year
or the interactive Rate chip, mirroring the TV FittedMetadataLine.
Episode rows replace the 'E0' primary-container chip with an inline
'3. Title' prefix that mirrors the server-provided number, including a
genuine episode 0. Phone section gaps drop from 24px to 12px so Cast,
Extras, and the related hubs share one rhythm; TV keeps its own values.
Both anchored popups were small tap targets on phones. AppMenuButton
gains an opt-in adaptiveSheet flag that routes through
showAdaptiveAppMenu: full-width, untitled sheet rows on touch platforms
(phones plus Android TV / tvOS), the same anchored popup on desktop.
Moving UP between hubs showed the focused card's glow immediately: the
glow paints in the root overlay, unclipped by the rail viewport, so it
flashed over the spotlight while the target row was still offscreen.
The rail now suppresses only the glow for the 250 ms vertical scroll
and lets it fade in once the row settles. FocusGlowOverlay defers
attached-portal shows out of build, which OverlayPortalController
asserts against.
Profile tiles and buttons drew the outline focus border while every
other settings surface highlights with a background fill. Tiles nest
the FocusableWrapper inside the Card so the fill paints above the
opaque card surface; buttons opt into useBackgroundFocus.
The QR sign-in screen stacked Retry above Cancel with intrinsic widths,
reading as sparse on a TV canvas and pushing Cancel off the bottom edge.
Both wait states now share one centered row, matching the player's
initialization-error surface.
The TV media detail page felt cramped on 1080p TVs (540 logical px): the
bottom rail's title strip, card label bands, and next-hub peek consumed
nearly half the screen and cut the next hub's posters mid-card at the
screen edge, while the hero packed logo, metadata, genres, summary, and
action row into 5-10 px gaps against the back arrow, shedding summary
lines to fit.
Slim the shared rail metrics (hub strip 36->30, next-hub peek 30->20,
label band 42->36, person labels 58->52, height slack 14->10) and the
detail page's rail card scale (0.8->0.72), then spend the freed height
on the hero: larger gaps between metadata/genres/summary/actions, a top
offset that clears the back button, and an info column widened from 57%
to 60% of the screen. Movie and show details now keep three spaced
summary lines, and the wider metadata line fits one more rating badge
before shedding.
The #1893 metadata-line regression test pinned the exact badge-shed
count at its test viewport; it now asserts rendered badges stay fully
on screen while keeping the quality-label guards.
On TV the detail hero caps the description at three lines with no way to
read the rest, and the fitted metadata line sheds rating badges and
quality labels when they do not fit, leaving that information
unreachable by D-pad.
The hero information block is now a focusable target: D-pad up from the
action row lands on it, and select (or tap) opens a sheet with the
complete metadata fields, every rating badge, the genres, and the
untruncated description. Long descriptions page with D-pad up/down.

The Android performance overlay showed only sample rate and channels for
EAC3, FLAC, DTS, TrueHD, and Opus tracks. The overlay reads the codec
from media3's Format.codecs, an RFC 6381 string only MP4/HLS provide
(hence AAC working), and the bitrate from Format.bitrate, which Matroska
carries only when the muxer wrote BPS statistics tags.
Fall back to the already-transmitted sample MIME type for the codec name
(audio and video), and measure the audio bitrate in the FFmpeg demuxer
from packet sizes over their pts span — the same source mpv uses for its
audio-bitrate property — when the container declares none.
close#2063
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.
close#2052
Plex's tag.tag- removes comma separated tags and has no escape syntax, so
removing a tag containing a literal comma ('Action, Comedy') split it at the
separator and could over-remove siblings named 'Action' or 'Comedy'.
Fields whose removals contain a comma now defer to one removal per request
after the main edit; every request restates the kept tags and the lock, so
the sequence converges regardless of order. Removals without commas keep the
exact single-request wire shape.
Hiding the chrome in the frame between the post-frame opaque mark and the
next build trusted an opaque flag the renderer never realized: hide() kept
controlsPresented while the fade-in target never rendered, so no fade-out
ran, markControlsHidden never arrived, and Back/Escape stayed swallowed
until a later show/hide cycle repaired the flag.
The controller's opaque flag now follows the real fade-in completion via
AnimatedOpacity.onEnd, so any hide it observes can rely on a fade-out that
will actually run. Branches that mount the chrome directly at full opacity
keep marking immediately, since those insertions fire no onEnd.
The Latest Albums see-all sheet offers a Date Added sort, but its rows were
requested without DateCreated, so addedAt mapped null and the sort silently
compared nulls — the same gap the earlier DateCreated work closed for catalog
and hub rows. DateCreated is a direct dto property, not one of the per-row
COUNT fields that motivated this set's slimness (#1552), so the cost profile
of these folder-dto requests is unchanged.
