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.
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.
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.
TRACES: UR-059 | DR-088, DR-089
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.
TRACES: UR-049, UR-050, UR-052, UR-053, UR-054, UR-055, UR-056
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.
- Standardize on bun: remove package-lock.json, add packageManager field,
gitignore non-bun lockfiles, fix stray npm install in android:build:clean
- Remove stale build logs and empty dirs (src-tauri/plugins, docs/tickets)
- Move android-dev.sh into scripts/
- Consolidate root docs into docs/ (docker/builder under docs/build/);
move the architecture overview to docs/architecture/README.md
- Extract Requirements Specification from README into docs/requirements.md
and slim README down to a project intro + docs index
- Fix internal references to the moved files
