- Embed DownloadQueueLookup into DownloadQueueState; add updatedForIndices() for O(changed) incremental updates during frequent progress ticks instead of full O(n) rebuild
- downloadQueueLookupProvider now reads pre-computed lookup from state directly
- Replace sync file deletion in DownloadedEmbeddedCoverResolver with unawaited async cleanup to avoid blocking the main thread
- Parse JSON payloads on iOS native side (parseJsonPayload) so event sinks and method channel responses return native objects, avoiding redundant Dart-side JSON decode
- Use .cast<String, dynamic>() instead of Map.from() in _decodeMapResult for zero-copy map handling
- Move explore JSON decode/encode to compute() isolate to avoid blocking main thread
- Memoize search sort results (artists/albums/playlists/tracks) in HomeTab; invalidate on new query
- Extract _DownloadedOrRemoteCover StatefulWidget with proper embedded-cover lifecycle management
- Replace O(playlists x tracks) in-memory playlist picker check with SQL loadPlaylistPickerSummaries query
- Add FutureProvider.family (libraryPlaylistPickerSummariesProvider) invalidated on all playlist mutations
- Memoize _buildQueueHistoryStats, localPathMatchKeys, and localSingleItems in QueueTab
- Add coverCacheWidthForViewport util; apply memCacheWidth/cacheWidth based on real DPR across all album/playlist/track screens
- Convert sync file ops in TrackMetadataScreen to async; use mtime+size as validation token
- Fetch Deezer album nb_tracks in parallel via fetchAlbumTrackCounts
- Tidal: use actual API track_number/disc_number when request values are 0
(fixes search/popular downloads having no track position in metadata)
- Extension enrichment: copy TrackNumber/DiscNumber back from enriched results
- Extension fallback download: add request metadata fallback for non-source
extensions (Album, AlbumArtist, ReleaseDate, ISRC, TrackNumber, DiscNumber)
- FFmpeg: add -v error -hide_banner to all commands (embed, convert, CUE split)
to eliminate banner, build config, and full metadata/lyrics dump in logcat
- ebur128: add framelog=quiet to suppress per-frame loudness measurements
while keeping the summary needed for ReplayGain parsing
- Track metadata screen: separate embedded lyrics check from online fetch,
show file-only state with manual online fetch button
- Add 'url' field (final URL after redirects) to all extension HTTP responses and fix fetch polyfill to return final URL instead of original request URL
- Fix RunWithTimeout race condition: increase force-timeout from 1s to 60s to prevent concurrent VM access crashes, add nil guards
- Use lockReadyVM() for thread-safe VM access in GetPlaylistWithExtensionJSON and InvokeAction
- Handle mixed JSON types (string, null, array) in SongLink resolve API SongUrls field
- Fix recommended download service not showing for extension-based searches in download picker
The info screen was not reading label/copyright from the actual file metadata, so these fields were always empty for local library items and download history items that lacked them in-memory. Now _resolveAudioMetadata() extracts and displays them without requiring a manual save first.
Sanitize the isrc getter to only return valid ISRC codes (12-char format per ISO 3901). Invalid values such as Spotify/Deezer/Tidal IDs that may leak into the ISRC field are now silently discarded, preventing them from being displayed or embedded into file tags.
- Default track/disc number to 0 (unknown) instead of 1, letting the
backend use the service-provided value or skip the field entirely
- Add releaseDate to ExploreItem so explore downloads carry release info
- Pass discNumber and releaseDate from extension album/playlist tracks
- Fix isDeezer detection using service field instead of substring match
- Add _displayServiceTrackId() to properly strip prefixes for all services
ReplayGain (track + album):
- Scan track loudness via FFmpeg ebur128 filter (-18 LUFS reference)
- Duration-weighted power-mean for album gain computation
- Support for FLAC (native Vorbis), MP3 (ID3v2 TXXX), Opus, M4A
- Album RG auto-finalizes when all album tracks complete
- Retryable gate: blocks finalization while failed/skipped items exist
- SAF support: lossy album RG writes via temp file + writeTempToSaf
- New embedReplayGain setting (off by default) with UI toggle
APEv2 tag support:
- Full APEv2 reader/writer with header+items+footer format
- Merge-based editing with override keys for explicit deletions
- Binary cover art embedding (Cover Art (Front) item)
- Library scanner support for .ape/.wv/.mpc files
- ReplayGain fields in APE read/write/edit pipeline
Bug fixes (26):
- setArtistComments wiping fields on empty string value
- APEv2 rewrite corrupting files with ID3v1 trailer
- APE edit replacing entire tag instead of merging
- ReplayGain lost on manual MP3/Opus/M4A metadata edit
- Editor metadata save losing custom tags (preserveMetadata)
- Album RG accumulator not cleaned on queue mutation
- Album gain using unweighted mean instead of power-mean
- writeAlbumReplayGainTags return value silently ignored

- Cancelled tracks polluting album gain computation
- APE ReplayGain not wired end-to-end
- APE field deletion not working in merge
- APE cover edit was a no-op
- Album RG duplicate entries on retry
- APE apeKeysFromFields missing track/disc/lyrics mappings
- Album RG entries purged by removeItem before computation
- FFmpeg converters discarding empty metadata values
- _appendVorbisArtistEntries skipping empty value (null vs empty)
- Album RG write-back fails for SAF lossy files
- Album RG partial finalization on failed tracks
- FLAC ClearEmpty flag destroying tags on partial callers
- clearCompleted not retriggering album RG checks
- ReadFileMetadata MP3/Ogg missing label and copyright
- Cover embed on CUE split destroying split artist tags
- Album RG gain format inconsistent (missing + prefix)
- FLAC reader/editor missing tag aliases (ALBUMARTIST, LABEL, etc.)
- dart:math log shadowed by logger.dart export
When deleting a non-CUE local library track from the metadata screen,
only the file was removed but the library database entry and provider
state were left untouched, causing the track to persist in the library UI.
Now calls removeItem() on localLibraryProvider after deleteFile().
Resolve API (api.zarz.moe):
- Refactor songlink.go: Spotify URLs use resolve API, non-Spotify uses SongLink API
- Add SongLink fallback when resolve API fails for Spotify (two-layer resilience)
- Remove dead code: page parser, XOR-obfuscated keys, legacy helpers
Multi-artist tag fix (#288):
- Add RewriteSplitArtistTags() in Go to rewrite ARTIST/ALBUMARTIST as split Vorbis comments
- Wire method channel handler in Android (MainActivity.kt) and iOS (AppDelegate.swift)
- Add PlatformBridge.rewriteSplitArtistTags() in Dart
- Call native FLAC rewriter after FFmpeg embed when split_vorbis mode is active
- Extract deezerTrackArtistDisplay() helper to use Contributors in album/playlist tracks
Code cleanup:
- Remove unused imports, dead code, and redundant comments across Go and Dart
- Fix build: remove stale getQobuzDebugKey() reference in deezer_download.go
Add singleFilenameFormat setting so singles/EPs can use a different filename template than albums. The format editor is reused with custom title/description. Dart selects the correct format based on track.isSingle before passing to Go, so no backend changes needed. Also fix isSingle getter to include all EPs regardless of totalTracks. Closes#271
Set systemNavigationBarColor to surfaceContainer (matching the in-app
NavigationBar) via AppBarTheme.systemOverlayStyle. Handles light, dark,
AMOLED and dynamic color schemes automatically.
Closeszarzet/SpotiFLAC-Mobile#284
Add a bottom sheet dialog that lets users choose which metadata field
groups to update during bulk re-enrich (cover, lyrics, album/album
artist, track/disc number, date/ISRC, genre/label/copyright).
Backend (Go):
- Filter FLAC Metadata struct and FFmpeg metadata map by selected
update_fields so non-selected groups preserve existing file values
- Guard Deezer extended metadata fetch with shouldUpdateField(extra)
- Title/Artist are never overwritten by re-enrich (search keys only)
- enrichedMeta response only includes selected field groups
Frontend (Dart):
- New re_enrich_field_dialog.dart bottom sheet with checkboxes
- FFmpegService embed methods gain preserveMetadata param that uses
-map_metadata 0 instead of -1 to preserve non-selected tags
- Hide selection overlay/bar before showing dialog, restore on cancel
- Fix setState-after-dispose guard in cancel branches
Cleanup:
- Remove dead code in library_tracks_folder_screen.dart
- Fix use_build_context_synchronously in main_shell.dart
- Suppress false-positive use_null_aware_elements lints
- Update l10n label from 'Title, Artist, Album' to 'Album, Album Artist'
- Delete dead metadata client and extract shared types to metadata_types.go
- Remove Yoinkify download fallback from Deezer, use MusicDL only
- Clean up retired settings fields and metadataSource
- Remove dead l10n keys for retired provider
- Add migration to strip retired provider from existing users' lyrics config
- Fix M4A/ALAC scan silently failing on Samsung by adding proper fallback
to scanFromFilename when ReadM4ATags fails (consistent with MP3/FLAC/Ogg)
- Propagate displayNameHint to all format scanners so fd numbers (214, 207)
no longer appear as track names when /proc/self/fd/ paths are used
- Cache /proc/self/fd/ readability in Kotlin to skip failed attempts after
first failure, reducing error log noise and improving scan speed on Samsung
- Fix Qobuz download returning wrong album cover when track exists on
multiple albums by preferring req.CoverURL over API default
- Fix FFmpeg M4A metadata save failing with 'codec not currently supported
in container' by forcing mp4 muxer instead of ipod when cover art present
- Clean up FLAC SAF temp file after metadata write-back (was leaking)
- Update LRC lyrics tag to credit Paxsenix API
- Remove log message truncation, defer to UI preview truncation instead
- Add artist_tag_mode setting (joined / split_vorbis) for FLAC/Opus multi-artist tags
- Split 'Artist A, Artist B' into separate ARTIST= Vorbis comments when split mode is enabled
- Join repeated ARTIST/ALBUMARTIST Vorbis comments when reading metadata
- Propagate artistTagMode through download pipeline, re-enrich, and metadata editor
- Improve library scan progress: separate polling intervals, finalizing state, indeterminate progress
- Add initial progress snapshot on library scan stream connect
- Use req.ArtistName consistently for Qobuz downloads instead of track.Performer.Name
- Add l10n keys for artist tag mode, library files unit, and scan finalizing status
- Introduce coverCacheKey parameter through Go backend and Kotlin bridge for stable SAF cover caching
- Add MetadataFromFilename flag to skip filename-only metadata and retry via temp-file copy
- Add Qobuz album-search fallback between API search and store scraping
- Extract buildReEnrichFFmpegMetadata to skip empty metadata fields
- Add metadata completeness filter (complete, missing year/genre/album artist)
- Add sort modes: artist, album, release date, genre (asc/desc)
- Prune stale library cover cache files after full scan
- Skip empty values and zero track/disc numbers in FFmpeg metadata
- Add new l10n keys for metadata filter and sort options
Add reusable BatchProgressDialog widget with circular/linear progress
indicators, cancel support, and track detail display. Uses ValueNotifier
pattern to communicate progress from caller to dialog across navigator
routes.
Move hardcoded UI strings across multiple screens and the notification
service into ARB-backed l10n keys so they can be translated via Crowdin.
Adds 62 new keys covering sort labels, dialog copy, metadata error
snackbars, folder-picker errors, home-tab error states, extensions home
feed selector, and all notification titles/bodies. NotificationService
now caches an AppLocalizations instance (injected from MainShell via
didChangeDependencies) and falls back to English literals when no locale
is available.
