A running JellyTau currently reports no version anywhere: not in the UI, not in
the logs. When a user reports "the equalizer does nothing on my device" there is
no way to tell whether they are on the v0.2.0 tag, master, or a three-week-old
local debug build — a live gap given v0.2.0's Android audio settings are not yet
device-verified.
Specifies a build.rs-emitted `git describe --tags --always --dirty`, a typed
BuildKind (Release/Untagged/Development/Unknown) classified in Rust rather than
pattern-matched in the UI, a get_build_info command, startup logging, and a
Settings > About block with copy-to-clipboard for bug reports.
Explicitly does NOT derive the release version from git: Cargo needs a literal
semver at manifest-parse time, so sourcing it from a tag would trade a
reviewable bump for a build-time dependency that fails in CI's shallow Docker
clones. The release version stays authored; only the provenance is derived —
they answer different questions.
Two constraints found while writing this:
- Only publish-docs.yml sets fetch-depth: 0. build-release.yml has five
checkouts and build-and-test.yml two, all of which would stamp "unknown"
as-is. Flagged as an acceptance criterion.
- tauri.conf.json's version field can be dropped to fall back to Cargo (three
hand-bumped files becomes two), but gen/android/app/build.gradle.kts reads
versionName/versionCode from generated Tauri properties, so that must be
verified before adopting rather than assumed.
ExoPlayerBackend was the only backend not overriding the PlayerBackend trait's
set_audio_settings/audio_settings defaults, so the Settings > Audio controls
rendered on Android and silently did nothing — the default returns Ok(()) while
applying nothing, so the failure was invisible.
Rust owns what the values are (canonical 10-band ISO layout, preset curves,
normalization presets); Kotlin owns when the AudioEffect objects exist, since
that needs the live audio session id.
- settings.rs: audio_settings_jni_payload() sanitises (crossfade clamped, band
vector normalised) before serialising, so a malformed vector cannot reach the
Kotlin parser. JSON rather than a wide JNI signature, matching how load()
already passes subtitles — adding a field will not change the signature.
- ExoPlayerBackend: set_audio_settings/audio_settings over JNI; ExoPlayerState
gains the first command-side field (settings are pushed out, never reported).
- JellyTauPlayer.kt: Equalizer, LoudnessEnhancer, and gapless via
pauseAtEndOfMediaItems.
Three details that are easy to get wrong:
- Effects re-attach on onAudioSessionIdChanged. ExoPlayer rebuilds its audio
sink on a format change, which invalidates effects bound to the old session;
without this the EQ silently stops applying mid-queue.
- All effect work is posted to mainHandler rather than run inline. AudioEffect
construction from a player callback can re-enter the player and deadlock —
the same shape as the AutoplayDecision lock-scrutinee bug.
- Device equalizers expose a device-dependent band count (commonly 5) at fixed
centres, so the canonical 10 bands are resampled by nearest centre frequency.
resampleBands() is a pure @JvmStatic function so that mapping is testable
without a device.
Normalization is approximate, not parity: LoudnessEnhancer is a gain stage, not
a true EBU R128 normalizer like MPV's dynaudnorm. Recorded as such rather than
claimed as equivalent.
Crossfade is deliberately excluded — unimplemented on every platform and
blocked on mpv, so building it on Android alone would invert the parity gap.
Tests written first and observed failing (cannot find function
audio_settings_jni_payload) before the implementation: the payload contract is
pinned by tests because a serde rename would otherwise silently break the
Kotlin parser.
Not yet verified on a physical device — AudioEffect availability and band
layouts are device-specific. Requirements matrix marks these rows accordingly,
and flipping the trait default to Err(not_implemented()) is deferred until that
verification lands.
Investigation into unifying the playback backends (Linux/MPV, Android/ExoPlayer,
Windows/webview) onto one engine with hardware acceleration. Conclusion: video
cannot be unified onto a native engine; audio can.
The blocker is not mpv-specific. WebKitGTK, WebView2 and Android WebView each
draw into their own compositor surface, so a native video surface sits either
entirely above or entirely below the webview and cannot interleave with HTML.
GStreamer and libVLC fail identically. mpv would additionally regress streaming:
it has no adaptive bitrate, while the current hls.js path does.
Six specs added:
- playback-backend-unification: the analysis and decision, with evidence
- android-audio-settings-parity: set_audio_settings on ExoPlayerBackend
- android-native-video-spike: timeboxed test of SurfaceView compositing
- windows-native-audio-backend: replace the webview <audio> shim with libmpv
- libmpv2-migration: dead libmpv git pin -> libmpv2, plus a LICENSE file
- playback-docs-corrections: the requirement-status fixes applied here
Corrections to requirements.md, all verified against source:
- UR-031/DR-034 claimed crossfade was "Done (Linux only)". It is implemented
nowhere (mpv_backend.rs has a bare TODO) and is architecturally blocked on
mpv, whose single-stream audio chain cannot feed acrossfade's two inputs.
- Parity matrix listed crossfade as a Linux/Android gap; it is neither.
- The matrix omitted the equalizer, which has the same Linux-only shape.
- The suggested ConcatenatingMediaSource is deprecated in current Media3.
nativeAdapter.ts cited tauri#10152 as an upstream blocker for native Android
video. That issue is a stale feature request, dead since 2024-07-01; the
capability shipped in tauri 27d01834 (2024-09-02), and the related
black-screen bug was fixed in wry 0.39.4 (we ship 0.55.x). What is genuinely
unproven is SurfaceView-behind-WebView compositing, which the spike now tracks.
A tap cannot be classified when it lands — it may still turn out to be
the first half of a double tap. Play/pause is therefore deferred until
the 300ms double-tap window closes, and cancelled outright if a second
tap arrives, so a double tap seeks without also toggling pause.
Forward skip moves from 10s to 30s (back stays 10s), for both double tap
and the keyboard arrows.
The timing rules live in tapGestures.ts so they are unit-testable
without mounting the player. Rapid double taps now chain off a
still-in-flight seek target instead of all resolving against the same
not-yet-updated position.
TRACES: UR-005, UR-061 | DR-092 | UT-085, UT-086, UT-087, UT-088
Records the search relevance and grouping behaviour as UR-060, with DR-090
(Rust relevance ranking) and DR-091 (Shows/Episodes split, People group,
stored-order migration). DR-066 now points at DR-091 for the current group set
instead of restating a default order that has since changed.
CLAUDE.md now states the failing-test-first rule explicitly: write a test
that reproduces the bug and watch it fail before applying the fix, and
extract buried logic into a plain .ts module so it can be unit-tested. A
test written against already-fixed code can pass for the wrong reason.
Skipping to the next episode left a mid-episode resume point behind, so
the skipped episode reappeared in Continue Watching with a partial
progress bar. Skipping means "done with this one", not "stopped here".
- reportSkippedEpisode marks the outgoing episode played instead of
reporting a stop position, and arms a one-shot suppression consumed by
the player's stop handler, so VideoPlayer's post-navigation unmount
stop report can't overwrite the 100% progress with the partial one.
- Continue Watching drops resume entries superseded by Next Up: an
in-progress episode whose series has a next-up entry strictly later in
series order (season, then episode) is hidden from the Home and TV
rows. Movies, series without a next-up entry, and items with unknown
or mixed ordering are always kept.
Adds UR-059, DR-088, DR-089.

Adds Docker-based packaging for Linux desktop (deb/rpm), Arch
(.pkg.tar.zst via makepkg), and Windows. Windows cross-compiles from
Linux via the official Tauri path — the x86_64-pc-windows-msvc target
driven by cargo-xwin — and produces an NSIS installer (nsis via
tauri.conf.json targets, since the CLI rejects --bundles nsis on a Linux
host). Verified end to end: builds jellytau.exe + jellytau_x64-setup.exe.
Unifies everything on one registry builder image (Dockerfile.builder):
Android SDK/NDK, rpm/file, clang(+clang-cl)/lld/llvm/nsis, cargo-xwin and
the msvc target. Packaging tools sit in a trailing layer so tool changes
rebuild in ~1min instead of ~15. Desktop stages are thin FROM
${BUILDER_IMAGE} layers; Arch uses a separate archlinux image.
CLAUDE.md: CI must install no system toolchains — everything lives in the
image. Bumps version 0.0.18 -> 0.1.0 (Windows support + webview audio +
equalizer).
TRACES: UR-003, UR-005 | DR-004
Adds a 10-band graphic equalizer to AudioSettings (enabled flag +
per-band dB gains, normalised to 10 entries and clamped to range).
Presets return gain curves; the settings page gains EQ UI. libmpv
applies the filter on Linux (Android parity pending). Old persisted
settings without EQ fields load as disabled + flat.
Also includes the requirements/traceability/ux-flows doc updates for
this feature and the home long-press routing (UR-058/DR-087).
TRACES: UR-027 | IR-020, DR-030 | UT-079, UT-080, UT-081, UT-082
The browsable Downloaded library + Transfers split + on-disk usage
(f25deba, plus today's grouping/perf fixes) fully implement UR-055 and
UR-056, but the requirements doc still listed them and DR-081..085 as
Planned. Flip to Done.
Also fix UT-id collisions: the downloaded-browse and formatBytes tests
reused UT-046..050 (already assigned to smart-cache/playlist tests in the
matrix). Reassign to UT-071..078 and register them in §4, including the
new music/TV container-rollup and orphan-leaf regression tests.
The DR-079/DR-080 root-cause fixes for issue #10 landed in 8f4f651; the
requirements doc still listed UR-052 (and DR-078/079/080, UT-068/069/070,
IT-016/017) as Broken/Partial/Pending. Flip them to Done and regenerate the
traceability matrix. Existing backend tests already cover the IT-016/017
end-to-end scenarios (annotated with their IDs in the code commits).
Settings page refactor plus supporting docs (requirements, ux-flows,
traceability) and the frontend-domain-model spec with implementation-status
banner. Removes SkeletonLoader and StorageManagement components (no remaining
references).
Add specs for the account menu, downloads-as-offline-library, offline
downloaded-only filter, and scoped search (+ boundary revision). Add the
new UR/DR entries to requirements.md, update ux-flows, and regenerate the
traceability matrix.

Hand video playback off to a native audio-only stream when the app is
backgrounded or locked, with no on-device video decode (UR-040). Adds
player_enter/exit_background_audio commands, an audio-only stream URL
for video items across the repository layer, and the frontend handoff
state machine wired into VideoPlayer. Includes accompanying
repository/offline/player refactoring and regenerates the traceability
matrix.
Add a docs-site (mdBook) with a Gitea publish-docs workflow, a
release-notes generator script (release:notes) that turns a commit
range's TRACES into grouped notes, the background-audio feature spec,
and CLAUDE.md. Ignore docs-site build artifacts.
Establish a decoupled player boundary so UI and backend interact with video
through one contract, with the HTML5 (Linux/interim-Android) and native
(ExoPlayer) providers as interchangeable primitive-executor adapters.
- PlayerAdapter interface + AdapterHost callback bag (adapters/types.ts): the
adapter owns only decision-free element PRIMITIVES (seekElement, reloadSource,
play/pause, setVolume, selectSubtitle); it never branches on strategy.
- Seek/audio-track DECISIONS stay in Rust (player_seek_video / _switch_audio_track
return a strategy); the facade dispatches the chosen primitive to the active
adapter. Both providers share the one decision path — logic lives once, in Rust.
- Facade holds the active adapter; a new ControlCommand PlayerStatusEvent lets
backend control (lockscreen/remote/sleep) drive the webview <video> element.
- Html5PlayerAdapter resolves the LIVE element via the bridge (fixes play/pause
silently no-opping when the element was re-bound).
- Do not emit a "stopped" player state on natural end-of-video: it flipped the
player/mode to idle mid-handoff and suppressed next-episode auto-advance under
a sleep timer. Jellyfin progress reporting is preserved; the backend's
on_video_playback_ended owns the transition.
- VideoPlayer net -300 lines (strategy/HLS-reload logic relocated to the adapter).
- Adds 20 adapter unit tests; existing suites stay green (vitest 457, cargo 416).

The offline/online switch was janky because two independent systems decided
"online" and never communicated:
- ConnectivityMonitor owned is_server_reachable (drove the UI banner) but
learned reachability only from a standalone /System/Info/Public ping loop
and from auth/login calls.
- HybridRepository served all real data by racing cache-vs-server but never
read or wrote reachability.
So the banner reflected a side-channel poller, not the system the user actually
experienced: a successful ping could read "online" while authenticated data
calls 401'd or timed out, and three different timeout regimes (5s ping / 30s
data / 100ms cache race) flapped against each other.
Unify into a single source of truth:
- Extract a cheap, cloneable ConnectivityReporter that owns all reachability
transitions and event emission.
- OnlineRepository reports the outcome of every server request to the reporter,
classified via RepoError: Ok/Authentication/NotFound/Server => reachable
(the server answered), Network => offline candidate, Database/Offline =>
ignored (not a server signal).
- Time-window debounce (OFFLINE_CONFIRM_WINDOW = 5s): flip offline only after
sustained network failure; recover instantly on the first success.
- Demote the ping loop to an offline-only recovery probe (no online polling;
real traffic is the signal when online).
- Frontend: navigator.onLine is now advisory (triggers a recheck instead of
forcing offline); removed the dead markReachable/markUnreachable store methods.
Docs updated (README, 07-connectivity, 03-data-flow, 02-svelte-frontend) to
describe the new model and fix pre-existing drift (HTTP client is 30s timeout +
5s ping, not the documented 10s/base_url).
Tests: 12 connectivity tests (debounce, instant recovery, RepoError
classification through report_outcome). Full suite: 398 Rust + 384 frontend
passing, svelte-check clean.
