Plex treats a subtitle stream as forced when its title says "Forced" even
with the API flag unset. Every forced comparison now uses that effective
forced-ness on both sides: the match scorer, the low-metadata hard gate,
the Jellyfin OnlyForced/Smart profile modes, and stream-index negotiation.
Carrying a track choice into the next episode no longer reuses the
same-item identity matchers. A sealed SubtitlePreference (off / track
reference / semantic intent) replaces the id-'navigation' pseudo-track
through the whole preference channel, and cross-item intents hard-require
language and forced-class parity. When the next episode has no track of
the same class, the intent declines and selection falls through to the
server's own per-episode choice instead of latching onto a full track by
position and persisting that mistake back to the server.
Intents wait for pending native tracks under the same catalog-completeness
rule as source ids, so an early decline cannot retire the selection
listener before the real track arrives.
Ref #1716
Plezy declares appCategory="video", so on Android Automotive OS it is a
parked app bound by car app quality DD-2/DD-3: audio must stop when the
vehicle starts driving and must not be resumable while driving. Two paths
kept audio alive. Music playback ran under a mediaPlayback foreground
service whose lifecycle observer was registered for Apple TV only, so it
never paused when Android backgrounded the app. Video pausing hung off
AppLifecycleState.hidden, which Flutter only synthesizes once Android
delivers onStop; a car without the Automotive compatibility mode delivers
onPause alone, which maps to AppLifecycleState.inactive and the player
ignored.
Gate every path that can start audio on a new lifecycle predicate,
automotivePlaybackAllowed, which permits playback on a car only while the
app is resumed and fails closed on an unknown lifecycle state. That covers
explicit play, gapless arming and track transitions, live retry and
channel switch, frame-rate-match resume, VOD/live startup, and the queue
navigation commands of the OS media session, plus a last-resort pause for
when the platform player resumes itself on native audio-focus regain.
Playback authority on the media-session router is deliberately left alone:
the router consumes a denied event, so gating it would swallow PauseEvent
and leave the OS unable to stop audio. Reacting to lifecycle callbacks is
the mechanism the platform documents as sufficient, so no android.car
dependency is added.
The music queue no longer requests POST_NOTIFICATIONS on a car, where the
foreground service and its notification never start: there is nothing to
authorize, and the prompt would take focus and make the gate discard the
first play intent.
Detect the form factor too: FEATURE_AUTOMOTIVE now vetoes the Android TV
verdict, so a rotary-only head unit no longer inherits the leanback
experience. Picture-in-picture is gated on FEATURE_PICTURE_IN_PICTURE,
which cars lack, so the app's UI cannot stay on screen while driving, and
nothing forces a preferred orientation on a fixed-orientation display.
Extracts the repeated toolbar fade into a single ToolbarScrim widget, folds
duplicated request/retry handling in the media server HTTP client, and
collapses the parallel playback-source, download-manager and live TV helper
paths into shared implementations.
Collapses indirection layers and one-caller abstractions across the video
player, shortcut dispatch, shader loading and context-menu code, including
the VideoPIPManager pass-through over PipService.
Replaces the imperative play/pause/seek/positionSync message soup with a
single host-authored PlaybackState (seq-ordered, anchor-extrapolated,
phase machine: loading/waitingForPeers/paused/playing) that doubles as
the heartbeat, plus guest status reports and host-applied control
requests. Fixes the guest seek-back loop while the host loads (readiness
was keyed on a pre-load !buffering snapshot and heartbeats broadcast
frozen positions), adds real group buffering coordination (stall grace,
scheduled simultaneous resumes, 15s safety timeout), rate-nudge drift
correction with passthrough-aware seek fallback, session-scoped message
handling (no lost messages during episode-switch detach gaps), and an
expected-state ledger replacing the racy remote-action flag.
