- 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
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
- SAF album RG writing to deleted temp path
- 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
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 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'
- 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 FFmpegService.embedMetadataToM4a() for writing tags and cover art
into M4A files via FFmpeg. Fix two bugs in the same function:
- Remove '-disposition:v:0 attached_pic' which is only valid for
Matroska/WebM containers and causes FFmpeg to error on MP4/M4A
- Apply same fix to _convertToAlac which had the identical issue
Add M4A handling (isM4A branch) to all four embed call-sites:
track_metadata_screen (lyrics embed, re-enrich, edit metadata sheet,
format conversion), queue_tab, local_album_screen, and
downloaded_album_screen.
Add 'LYRICS'/'UNSYNCEDLYRICS' to _mapMetadataForTagEmbed so existing
lyrics survive a re-enrich cycle on M4A/MP3/Opus files.
Preserve existing lyrics before overwriting tags in the edit metadata
sheet (best-effort readFileMetadata before FFmpeg pass).
Extract mergePlatformMetadataForTagEmbed() into lyrics_metadata_helper
to deduplicate the identical metadata-mapping loops that existed in
queue_tab, local_album_screen, downloaded_album_screen, and
track_metadata_screen.
Wire ensureLyricsMetadataForConversion into the format conversion path
in track_metadata_screen so lyrics are carried through conversions.
Add ISRC and LABEL/ORGANIZATION mappings to _convertToM4aTags.
Exclude same-format and lossy-to-lossless targets from the batch
convert sheet so users cannot pick pointless conversions like
FLAC→FLAC. Also clean up redundant inline comments.
- Use -map_metadata 0 instead of -map_metadata -1 so FFmpeg copies and
auto-remaps source tags (M4A/ID3 → Vorbis comments) as a base
- Add _normalizeToVorbisComments() to filter technical fields (BIT_DEPTH,
SAMPLE_RATE, DURATION) and normalize key variations to standard Vorbis
comment names before applying overrides
- Switch cover art embedding from METADATA_BLOCK_PICTURE base64 (unreliable
on Android due to command-line length limits) to -i cover -map 1:v
-disposition attached_pic (same proven approach as embedMetadata and
_convertToAlac)
- Drop zero-value track/disc numbers from override map to prevent
clobbering source metadata with '0' from Go readFileMetadata
- Add _convertToAlac() and _convertToFlac() in ffmpeg_service with
single-pass FFmpeg encoding, metadata tags, and cover art embedding
- Wire lossless formats (ALAC, FLAC) into single-track convert sheet
with dynamic format list based on source format, hidden bitrate for
lossless targets, and lossless hint text
- Add lossless conversion to batch convert UI in downloaded_album,
local_album, and queue_tab screens with lossy-source filtering
- Fix M4A quality probe in Go backend: increase audio sample entry
buffer from 24 to 32 bytes, read sample rate from correct offset
(bytes 28-29) and bit depth from samplesize field (bytes 22-23)
- Add l10n keys for lossless confirm dialogs and hints (en, id)
Parse .cue files in library scanner (Go + SAF) to display individual
tracks instead of one large audio file. Add FFmpeg-based CUE splitting
to extract tracks into separate FLAC files with embedded metadata and
cover art.
- Go: CUE parser, two-pass scan (CUE first, skip referenced audio),
virtual paths (cue#trackNN) for DB UNIQUE constraint, audioDir
override for SAF temp-file scenarios
- Android: SAF scanner recognizes .cue in both full and incremental
scan, copies .cue+audio to temp for Go parsing, unchanged-CUE audio
sibling dedup, parseCueSheet handler resolves SAF audio siblings
- Dart: FFmpegService.splitCueToTracks, CUE split UI in track metadata
screen, persistent output dir for SAF splits with write-back
- CUE virtual path normalization across fileExists/fileStat/deleteFile/
openFile; play/share/open blocked for virtual tracks with guidance to
split first; delete only removes DB entry, not shared .cue file
- iOS: parseCueSheet handler
- Localization: 12 new CUE-related strings
