Offline video never started: the <video> element reported NETWORK_NO_SOURCE
one millisecond after loadstart, which the UI mislabelled as "may need
transcoding" even though nothing had been fetched. Two independent causes,
both required for playback.
The path was doubled. `downloads.file_path` is stored relative to the storage
root while a download is queued, but the worker rewrites it to the absolute
path it actually wrote once the transfer completes — so a completed row is
already rooted. The player's offline branch rooted it a second time, producing
/data/user/0/app//data/user/0/app/videos/x.mp4. Audio was unaffected because it
resolves the same column through Rust's resolve_local_media_path, which does
not re-root. The join is now absolute-aware (POSIX, Windows drive letters, UNC)
so rows written before completion still resolve.
The asset protocol was never enabled. convertFileSrc rewrites a path to
http://asset.localhost/… unconditionally, but Tauri only answers that origin
when the protocol-asset cargo feature is compiled in *and*
app.security.assetProtocol.enable is set — neither was, so even a correct path
resolved to nothing. This also silently defeated the cached-thumbnail path in
imageCache, which fails soft to the server copy and so hid the breakage
whenever the server was reachable. Scoped to $APPDATA/** — the storage root
holding the database, downloads/ and the thumbnail cache — rather than an
unrestricted grant.
Diagnosed from logcat on device; UT-124 reproduces the doubled path.
MediaCodecList answers "can this device decode 5.1", which is not the
question that decides whether the user hears anything: a phone decodes an
AC-3 5.1 track happily and still has two channels to play it out of. The
DeviceProfile carried no MaxAudioChannels, so Jellyfin was free to
direct-play the multichannel track to a two-channel sink — silence or
dialogue folded into surround channels that go nowhere, depending on the
device.
Report media3 AudioCapabilities.maxChannelCount for the current route over
JNI alongside the codec lists, and bound the direct-play and transcoding
profiles (and the HLS URL's TranscodingMaxAudioChannels, previously
hardcoded to 2) by it. No codec is ever removed, so a device with genuine
surround output keeps direct-playing it. A missing or zero reading means
"route not yet established", not "no audio", and falls back to stereo.
Jellyfin's MediaStream.Index is global across every stream in a media
source, so index 0 is the video stream on virtually all files. We sent
AudioStreamIndex=0 as "the first audio track" on the HLS transcode URL,
the background audio-only handoff URL, the direct-play fallback URL and
the PlaybackInfo negotiation body — asking the server to use the video
stream as audio. Servers that honour it produce a picture with no sound;
only those that silently correct the index hid the bug, which is why it
surfaced as "some videos have no audio".
Omit the parameter unless a track was actually chosen, so the server
resolves the source's DefaultAudioStreamIndex. An explicit selection from
player_switch_audio_track still passes through unchanged. Dropped
outright from the static=true direct-play URL, which serves the original
file untouched.
The hybrid favourites read went straight to the online repository on a
cache miss and dropped the result on the floor. Every other read path
persists what it fetches, so this one made the favourites page re-query
the server on every visit — and left the offline mirror (DR-114) empty on
a fresh install, since this is the path that fills it.
It now goes through get_favorites_server_only, which saves through on the
way back.
The command had a matching hole: with nothing cached it returned the empty
result, painting "Nothing favourited yet" at a viewer whose favourites
were simply marked on another client. It now asks the repository for a
real answer instead of an empty state it would correct a round trip later.
TRACES: UR-067 | DR-115
A recoverable player error meant "playback is over": the frontend's error
handler stopped the player unconditionally, so a wifi blip killed the
track. Android already decides in its JNI callback, but MpvBackend is
constructed before PlayerController exists, so its event thread has no
controller to ask.
So MPV reports the failure and the frontend echoes it into the new
player_recover_stream command — the same shape as PlaybackEnded ->
player_on_playback_ended, keeping the decision in Rust. The command
re-opens the stream where it stopped, with the existing attempt budget
and backoff, and returns whether it handled it; only a false answer
falls through to the old stop path.
Android now reports the errors it has already declined as
*unrecoverable*, so the echo never asks the same question twice.
TRACES: UR-004, UR-040 | DR-130 | UT-117
Search's instant leg read only downloaded items, so with no downloads it
returned nothing and every keystroke fell through to a full Recursive=true
server query. It now reads the whole synced catalog through the same
availability CTE get_items uses, gated on the same include_catalog_browse
flag so search and browse cannot diverge. (UR-065, DR-108)
Also fixes three defects found while confirming that:
- items_fts grew by a full duplicate index every catalog pass. INSERT OR
REPLACE fires no AFTER DELETE trigger without recursive_triggers, so the
old index row was orphaned, and a TEXT PRIMARY KEY meant the replacement
took a fresh rowid and inserted a second entry. Now a real upsert, with
migration 021 rebuilding existing indexes. (DR-110)
- DELETE FROM items existed nowhere, so server-side deletions never
propagated. Adds a post-crawl mark-and-sweep, scoped to crawled types,
skipping downloaded items, and refusing to run after a partial crawl
because items.parent_id cascades. (DR-110)
- The index omitted MusicArtist, Playlist and People, which search groups
results by. Adds them plus people_fts (migration 022). (DR-111)
Re-indexing moves from a frontend startup call to a Rust background task
with a 6h TTL, so a long session no longer searches a stale catalog and a
restart no longer forces a crawl regardless of freshness. (DR-109, IR-030)
Downloads gain a lifetime tier. Eviction selected every completed row by
age with no download_source filter, so hitting the storage limit deleted
the oldest download -- typically one saved deliberately for offline -- to
make room for a precached track. It now reclaims only 'auto' rows, and
expired ones are reclaimed first, before live cache is evicted.
(DR-126, DR-127)
Downloaded video and audio-only handoffs now play from disk instead of
streaming; the video path had never consulted downloads at all. No
transcode is involved: MPV runs video=no and ExoPlayer has no surface for
an Audio item. (DR-123 in part, DR-128)
FTS queries are built as quoted phrases so apostrophes, hyphens and
slashes are data rather than operator syntax, and the item-type filter is
bound rather than interpolated.

Includes concurrently-developed favourites browsing and background-audio
stream-end handling; the two workstreams share offline.rs, lib.rs and
online.rs, so no subset of files builds independently.
The bottom nav rendered under the Android navigation bar, and full-screen
playback controls spilled into unusable screen edges. It looked device-specific
(Motorola bad, Fairphone fine) but every device was equally unpadded — only the
intrusion differed: a tall opaque 3-button bar swallows the nav, a thin
translucent gesture pill overlaps harmlessly.
None of the app's safe-area handling was ever active, for two independent
reasons:
1. app.html had no `viewport-fit=cover`, so every `env(safe-area-inset-*)`
resolved to 0px — the padding in app.css and BottomUi was a no-op.
2. Android WebView maps only the *display cutout* into `env()`; the status bar
and navigation bar are never reported. With enableEdgeToEdge() and
targetSdk 36 (enforced from 35, opt-out ignored from 36) the WebView always
spans them, so CSS could not learn about them by any route.
WindowInsetsBridge now reads `systemBars() | displayCutout()` and publishes
`--jt-inset-*` CSS custom properties, both pushed on every inset change
(rotation, nav-mode switch, PiP) and pullable via `AndroidInsets.get()` — the
pull is required because the first inset pass lands before the document exists
and a page load wipes the pushed inline style. app.css folds them with `env()`
via `max()` into `--safe-*`, the only thing components may pad from.
Exactly one element owns each edge: the shell takes top/left/right, BottomUi
takes bottom (inside its surface box, so the colour extends behind the gesture
bar), and shellReservesBottomInset hands bottom back to the shell on routes with
no bottom UI. The full-screen players inset their control layers only, leaving
video and artwork edge-to-edge.
The theme's `fitsSystemWindows=true` claimed the opposite of what actually
happened — overridden at runtime, ignored at this target SDK — and is removed.
Also converts six nested `h-screen`/`min-h-screen` boxes to `h-full`: the shell
is `h-screen` *and* inset-padded, so its content box is `100vh - safe-top` and
any nested 100vh box overflows by exactly the inset (the library column would
have clipped its own BottomUi). A test guards against reintroduction.
Opening a series dumped the viewer at the top of season 1, and its Play
button played nothing at all: it resolved `$libraryItems[0]` — the first
*season* by SortName — and navigated to `/player/<seasonId>`, which the
player route bounced straight back to `/library/<seasonId>`.
The backend could already answer "where is this viewer in this show":
`repository_get_next_up_episodes` has accepted a `series_id` since it was
written and no caller had ever passed one.
Backend (DR-101, DR-106)
- `repository/series_progress.rs`: `pick_current_episode` — in progress,
else Next Up, else first unwatched, else the premiere. The third rung is
the offline path, where Next Up is always empty. `sort_series_order` puts
specials (season 0) after the numbered seasons.
- `repository_get_series_episodes` takes over the season fan-out and the
flat-series fallback, which were domain knowledge living in the frontend.
- `clear_watch_history` maps to Jellyfin's mark-unplayed (recursive over a
container, also zeroes resume). Offline it refuses rather than diverging
state the next sync would undo.
Frontend (DR-102, DR-103, DR-104, DR-107)
- Seasons collapse; only the current one is expanded, and the current
episode is badged and scrolled into view.
- Hero button reads `Resume S2E4` / `Play S1E1` and opens that episode's
focus view, where Play commits (ux-flows §5B.5).
- Seasons are no longer a destination: `/library/<seasonId>` redirects to
`/library/<seriesId>#season-N`, and every inbound link follows.
- The "More Episodes" strip spans the whole series, so a season finale
offers the next premiere instead of dead-ending (§5B.2).
- Clear-history buttons on the series hero and each season header.
Routes (DR-105)
- `/library/tv` and `/library/movies` absorb their all-titles and genres
pages as `?view=` tabs; the four legacy routes redirect. 6 video routes
become 2, and `/library/shows/genres` stops being the odd one out.
Logic extracted to `seriesNavigation.ts`, `episodeStrip.ts` and
`libraryView.ts` so it is unit-tested rather than buried in components.
Spec: docs/specs/series-current-episode-navigation.md
Leaving a video and returning to it rendered the movie/episode in
AudioPlayer. Closing a webview-rendered video deliberately emits no
"stopped" state (that would break the autoplay handoff), and the
direct-play path does not stop the backend on unmount, so the Rust
controller still reported that item as its loaded media. Re-entering the
route therefore took the "already playing, just show the UI" shortcut,
which returns before a stream URL is fetched, and the render fell
through to the audio surface. Mostly visible on Android, where video
direct-plays; Linux transcodes and stops the backend on unmount.
Both decisions move into playerSurface.ts as pure functions:
shouldReuseActivePlayback excludes video, so video always takes the full
load path and gets its stream URL and resume position;
resolvePlayerSurface maps video-without-a-stream-URL to "pending"
(spinner) rather than falling through to audio.
An episode played audio-only while the app was backgrounded stalled at the
episode boundary instead of advancing, and ExoPlayer parked in STATE_ENDED —
where any later play intent (lockscreen, headset, Bluetooth reconnect) replays
the ended item, surfacing as the episode randomly restarting.
End-of-playback is dispatched from two places and they disagreed. The Android
JNI callback carried the background-audio branch but can never reach it:
load_and_play sets EndReason::NewTrackLoaded at every load and nothing clears
it, so the first real end consumes it and the decision is always Stop. The call
that actually decides is the frontend's echo of the resulting PlaybackEnded into
player_on_playback_ended — and that path had no background-audio case at all, so
it started a countdown whose advance is a webview goto() that cannot start audio
while backgrounded.
Both dispatchers now share PlayerController::auto_advance_to_next_episode, so
they cannot drift apart again.
The handoff base offset moves from the BackgroundAudioOffset Tauri state onto
the controller, and the advance clears it: the next episode's stream is built
without StartTimeTicks, so its timeline is already absolute and a stale base
made player_exit_background_audio return old_base + position_in_new_episode.
Unreachable until the advance actually worked.
Tests (red before the fix):
- test_auto_advance_background_audio_episode_advances_in_backend
- test_auto_advance_foreground_video_episode_uses_countdown
- test_advance_to_next_episode_audio_only_clears_handoff_base
Bump to 0.2.9.
On Android, dragging or tapping the progress bar moved the thumb but
playback stayed where it was. Two separate defects, both touch-only,
which is why the mouse-driven scrub tests never caught either.
1. Gesture hijack. DR-098 taught handleTouchStart to ignore touches that
land on a control, but handleTouchMove kept running. It measures
against touchStartX/Y, which that early return leaves at the PREVIOUS
gesture's values, so a seek-bar drag produced a huge bogus vertical
delta: read as a brightness swipe, it dimmed the screen to the 0.3
floor and fired a spurious play/pause "correction" mid-drag. A gesture
is now latched at touchstart (playerGestureActive) and touchmove
ignores anything unlatched — re-checking the move target cannot
recover a start point that was never recorded.
2. Commit signal. The seek was committed only from `change`, which
Android's WebView does not reliably fire for a touch interaction on a
range input, so the thumb moved to the tapped position and no seek
ever ran. touchend/mouseup now commit too; `input` arms a one-shot
latch so whichever release signal arrives first commits and the other
is a no-op. seekRelative shares the same commitSeek entry point
instead of fabricating a synthetic change event.
Tests drive the slider with real touch events (UT-089, UT-090) and fail
against the pre-fix component.
Both still described the 300ms deferred-tap design that DR-098 replaced
with immediate action, so the generated release notes advertised
behaviour the code no longer has.
After the DR-098 tap rewrite, pausing became impossible while unpausing
always worked — an asymmetry that pointed straight at the overlay.
Pausing renders a full-screen play-overlay button over the video. The
compatibility click Android synthesizes from the tap arrives ~30-130ms
later, by which time that button exists, so the click lands on the
OVERLAY rather than the <video>. Its onclick called togglePlayPause with
no guard at all, resuming immediately. Unpausing was unaffected because
it removes the overlay, leaving nothing to intercept the click.
The suppression rule was only wired into the video element's handler.
Extract it as isSynthesizedTouchClick() in tapGestures.ts (unit-tested)
and use it from every click target layered over the video, the overlay
included.
Verified: 724 frontend tests pass, svelte-check clean. Bumped to 0.2.5
so the APK installs over 2004.
Tapping the video surface pause-looped: it would unpause and bounce
straight back to paused about a second later. Long-press unpaused fine,
which is what pinned it to the tap path rather than the media pipeline.
The gesture handler deferred the first tap's play/pause behind a 300ms
timer so a second tap could cancel it and seek instead. But the timer
callback cleared its own handle *before* invoking the toggle, and
handleVideoClick used exactly that handle (`tapTimeout !== null`) to
suppress the compatibility click Android's WebView synthesizes after a
touch. So the guard was already open when the late click arrived, and it
toggled a second time.
Replace the deferral with immediate action — there are only first and
second taps:
1st tap: toggle play/pause
2nd tap: seek, then toggle play/pause again
The second toggle undoes the first, so a double tap seeks while leaving
the play state exactly as it was: playing jumps and keeps playing,
paused jumps and stays paused. No timer, no window race, no loop.
Click suppression no longer depends on the timer: ignore detail === 0
and any click within 700ms of a touch tap, since Android can deliver the
synthesized click late and with a real detail value.
A swipe now undoes the touchstart toggle (latched on swipeGestureActive
so it happens once, not per touchmove frame), keeping brightness swipes
from changing the play state.
UT-085..087 described the old deferred behaviour and are updated to the
new contract. UT-091 is used for the DR-097 facade tests, since UT-089
and UT-090 were already claimed by extract-traces.test.ts.
Video on Android/Linux renders in a webview <video> element, and the
frontend facade short-circuited play/pause/toggle straight into the
adapter whenever one was registered. Html5PlayerAdapter.toggle() then
decided play-vs-pause by reading el.paused off the DOM, so the Rust
controller never saw the intent and could not serialise competing ones.
el.paused flips transiently while an element buffers or settles a seek.
Two intents ~150ms apart therefore read *different* values and performed
*opposing* actions — one playing, one pausing — which self-sustained a
play/pause loop that needed no further input. On device this showed up
as a fully healthy element (readyState=4, networkState=1, not seeking,
not buffering, not ended) pausing itself roughly once a second, so
unpausing or skipping ahead bounced straight back to paused.
The root cause was that Rust held NO state for webview-rendered media:
report_html5_state only re-emitted its argument, despite the comment
above it claiming the controller was the single source of truth. It had
nothing to decide a toggle from.
Now report_html5_state tracks the reported state, and play/pause/toggle
consult it and drive the element by emitting a ControlCommand — the same
"backend decides, adapter executes the primitive" split player_seek_video
already uses. A stopped/idle report clears the tracking so MPV/ExoPlayer
regain authority for music playback.
Tests cover the loop signature directly (repeated toggles must alternate,
never repeat or oppose) plus a guard that one intent yields exactly one
ControlCommand — which matters on Windows, where the backend is itself
webview-based and could otherwise be driven twice.
Html5PlayerAdapter.play() reported every interrupted play attempt as a
player error. While an HLS stream stalls, hls.js' gap-controller nudges
the element to recover, which cancels the pending play() promise and
raises AbortError ("play() request was interrupted by a call to
pause()"). That is transient — the element is still trying to play — but
it hit host.onError roughly once a second for the whole stall, leaving
the UI stuck reporting paused.
Treat an interrupted play as a debug-level non-event, and memoise the
in-flight attempt so the UI and recovery paths share one element.play()
rather than stacking calls that abort each other.
This is the loop amplifier, complementing DR-095 which removed the
dead-segment stall that triggered it.
Note: webviewAudioAdapter.play() has the same raw shape but is not
implicated — audio playback does not go through hls.js — so it is left
unchanged rather than widening this fix.
Seeking near the end of a transcoded video locked the player into a
stall/pause loop: unpausing or skipping bounced straight back to paused.
Both seek paths clamped the target to exactly `duration`. hls.js then
requested the segment whose start time lies *past* the end of the media
(a 6330.324s item asks for segment 1055, starting at 6336.33s). Jellyfin
never produces that segment, the fetch times out, and the gap-controller
stalls forever at the last buffered position — retrying ~1x/second and
firing an endless stream of AbortErrors as play() lands mid-nudge.
Clamp strictly inside the media instead, keeping one segment length
(6s) of margin, floored at 0 so short media still seeks to the start.
The seek-bar drag path needed this too: its range input `max` is the
duration itself, so dragging fully right produced the same dead target.
Also bumps the requirement-count fixture for the new DR-095 row.
check:boundary passed on the very leak it was written for. The pattern was
anchored to `includeItemTypes:` at the query site, so searchScope.ts
assigning the same array to a named const and dereferencing it one
indirection away was invisible — through every green CI run.
The check now matches an array literal naming two or more Jellyfin item
types anywhere in src/, catching a const, a Record value, a function
return, and an inline query alike. Deliberate limits kept: two adjacent
literals required (single-type presentation stays legal), string literals
required (item.type === "Audio" is display logic), explicit type list
(so ["High","Low"] produces no noise).
Verified all five cases: reintroducing the original SCOPE_ITEM_TYPES
fails; a new const ["Movie","Series"] fails; the same array in a
.test.ts passes; itemType: "Movie" / item.type === / ["High","Low"] pass;
a 5th allowlist entry fails on the new cap.
Allowlist 1→3 entries, capped at 4 so the next exception forces a
conversation rather than a one-line append:
- GenericMediaListPage: grid styling over a self-declared itemType —
presentation, changes only with a UI redesign.
- DownloadedBrowse: borderline, leans domain (the container set grows
when Jellyfin adds a container type). Allowlisted with a TODO for a
backend MediaItem.isContainer flag.
The header now names what the check still cannot see — run-time-built
sets, types split across variables, switch/|| taxonomy — and CLAUDE.md
states that a green check:boundary is not proof. That matters given this
check passed on its own founding violation for months.
Also: both gates wired into test-all.sh, which called `bun run test`
without --run and would have hung in watch mode. Corrected the Dockerfile
comment describing the Windows toolchain as mingw/GNU — it is MSVC via
cargo-xwin (GNU cannot bundle NSIS from Linux).
Stage 1 of scoped-search-boundary-implementation.md — the query side.
scoped-search-boundary.md diagnosed this leak, specified the fix in
detail, and became the justification for the boundary rule in CLAUDE.md,
the check:boundary tripwire, and the spec-review checklist. The fix was
never built: SCOPE_ITEM_TYPES was still live in searchScope.ts, called by
library.ts, and no SearchScope existed anywhere in src-tauri/. The rule's
own founding violation was still shipping.
Rust now owns the taxonomy:
pub enum SearchScope { All, Music, Movies, Tv }
impl SearchScope { pub fn item_types(self) -> Option<Vec<String>> }
- SearchOptions gains `scope`, resolved by resolve_scope(). Scope wins
over include_item_types, which stays for the non-search get_items
callers that legitimately request one concrete type.
- repository_search resolves the scope ONCE, before the cache/server
paths diverge, so online and offline filter identically — the failure
mode most likely to go unnoticed.
- All expands to None (no filter), not the union of the other scopes:
an explicit includeItemTypes list would silently drop People, folders,
and any type nobody enumerated.
- searchScope.ts re-exports SearchScope from generated bindings instead
of a hand-written union, and no longer names an item type for search.
- library.ts sends { scope }.
8 Rust tests written first, confirmed failing on "use of undeclared type
SearchScope" before the implementation existed.
The frontend tests that asserted includeItemTypes contents were rewritten
to assert the opaque scope is sent and includeItemTypes is absent —
keeping the old assertions would require the frontend to know the
taxonomy again, defeating the fix. The expansion is now asserted in Rust.
Verified the spec's headline criterion by hashing every src/ file, adding
"AudioBook" to the Music scope in Rust, and re-hashing: zero frontend
files change. That criterion failed before this commit.
Stage 2 (result-side grouping: GROUP_ITEM_TYPES, GroupedSearchResult on
both search payloads) remains open.
The coverage gate divided traced counts by hardcoded literals (UR/39,
IR/24, DR/48, JA/3, TOTAL_REQS=114) that had fallen out of date as
requirements grew to 211. It reported 158% coverage — JA alone printed
800% — so the 50% threshold was mathematically unreachable and the job
could not fail. Coverage could have collapsed to 30% and CI would still
have printed a green tick.
Real coverage is 86%. The number was fine; the gate was dead.
extract-traces.ts now owns both sides of the fraction:
- countDefinedRequirements() counts an ID only where it leads a markdown
table row, ignoring the "Traces To" column and prose. IDs are
deduplicated because requirements.md lists every UR twice (§1
definition + §3 matrix), which would otherwise report UR as 121/61.
- computeCoverage() uses the intersection of traced and defined IDs, so
a TRACES comment naming a deleted or typo'd requirement is reported as
`orphaned` rather than inflating the ratio past 100%. UT/IT test
identifiers are excluded as a separate taxonomy.
- CI reads .coverage.percent and fails on <50% or >100%; a >100% reading
is now a hard error rather than the condition that hid this bug.
- New `bun run traces:coverage` runs the same computation locally.
- scripts/ added to the scan roots — the coverage tool was invisible to
the matrix it generates.
Tests written first (15, over fixtures so they don't drift as
requirements are added). vitest include widened to scripts/** so build
tooling is covered by the normal suite.
Verified empirically rather than by inspection: forcing the threshold to
99% fails; adding a requirement lowers coverage 86%→85%; a TRACES: DR-999
lands in `orphaned` without changing `covered`.
traceability-ci.md documented the same stale numbers and would have let
the broken arithmetic be reconstructed — replaced with a pointer to the
live command.
Audit of the principles in CLAUDE.md and docs/architecture/ against the
actual code. Principles with a working automated check (poison-tolerant
locking, Android source sync, one-directional playback state, graceful
backend init, reachability-from-traffic) all held up. The two that drifted
are exactly the two whose checks were broken or too narrow:
- traceability-gate-repair: CI divided by hardcoded denominators
(UR/39, IR/24, DR/48, JA/3, total 114) while requirements.md had grown
to 211, reporting 158% coverage — the 50% threshold was unreachable and
the job could not fail.
- req-coverage-script-removal: check-req-coverage.sh reports
"1 requirement" and prints "all requirements have implementations".
- scoped-search-boundary-implementation: the founding boundary incident
was specced but never built; the leak is still live.
- boundary-tripwire-hardening: check:boundary passes on that same leak —
the pattern is anchored to the query site, so a named const evades it.
- player-facade-enforcement: 52 direct commands.player* call sites
outside the facade, and no automated check at all.
Each spec follows SPEC-TEMPLATE.md with a filled-in Layer assignment

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 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.
