Audio-only mpv core on every platform (dedicated
com.plezy/mpv_audio_player channels): parameterized android/windows/
linux mpv plugins and a new apple MpvAudioPlayerCore, all skipping
video/window paths (vid=no, audio-display=no, gapless-audio=weak).
MusicPlaybackService drives an in-memory queue with shuffle/repeat,
file-loaded-event gapless arming (property edges coalesce and the
android bridge drops them), per-track progress reporting, OS media
controls, audio focus, sleep timer, and error auto-skip.
PlaybackCoordinator enforces one live native player: starting video
disposes the audio core first.
Player backends share static per-backend EventChannel names, so two
overlapping instances (episode handoff, quick exit/reopen) collide:
the newer instance's listen displaces the older sink, the older
instance's late cancel then tears down the newer stream — silently
freezing its events — and the final cancel earns the engine's
"No active stream to cancel" reply, which the framework can only
report as an uncatchable fatal FlutterError (363 events).
Track the owning instance per channel: only the current owner sends
the native cancel; a displaced instance drops its dead subscription.
Residual benign teardown races are dropped in beforeSend.
- Extract track lifecycle logic from VideoPlayerScreen (3248→2928 lines) into TrackManager
- Parse isDefault/isForced for subtitle tracks in parseTrackList
- Emit forced flag from ExoPlayer's emitTrackList
- Fix detectSubtitleMimeType failing on URLs with query params
- Add missing external_ ID prefix in ExoPlayer addSubtitleTrack
- Replace polling loop with stream in selectAndApplyTracks
- Handle play() failure in resumeAfterSubtitleLoad
- Handle addExternalSubtitles failure in onBackendSwitched
Catch COMMAND_FAILED/NOT_INITIALIZED in PlayerNative.seek() and
PlayerAndroid.seek() directly, preventing unhandled PlatformException
crashes on macOS app resume. Remove the ~200-line
_PendingSeekCoordinator system and revert all callsites to direct
player.seek(clampSeekPosition(...)). Keep seekable property/stream
and media controls gating. Add ExoPlayer seekable emission.
- Default MPV native log level to "warn" instead of "v" (Linux/Windows),
add setLogLevel method channel to raise it when debug logging is enabled
- Coalesce MPV render requests via atomic compare_exchange on needs_redraw_
- Clear redraw flag before render so new redraws queue during current frame
