Problem

Video seek intervals were fixed, audiobook preferences stayed in the browser, and different controls could jump by different amounts.

Related issue: #988

Approach

Add separate video and audiobook rewind/fast-forward preferences under Settings → Playback → Seek controls. Contract revision 9 stores them for the active profile, with presets from 5 to 90 seconds and defaults of 10 seconds back and 30 seconds forward. Existing browser-local audiobook values require an explicit import, with partial failures reported per direction.

Route buttons, keyboard shortcuts, gestures, focused sliders, minimized playback, and supported media controls through the resolved intervals. Repeated skips accumulate from a pending seek target during stream reanchoring. Absolute seeks, chapter navigation, and automatic resume rewind retain their own semantics.

Reuse the settings API and generated bindings without a database migration or playback-protocol change. Native adoption is tracked in Silo-Server/silo-apple#267 and Silo-Server/silo-android#300.

Validation

  • Passed Go build, gofmt, vet, and golangci-lint against the merge base; relevant settings/API tests passed.

  • Passed web lint, formatting, TypeScript, and the production build.

  • Passed all 3,144 web tests in 367 files with NODE_OPTIONS=--no-experimental-webstorage make test-web, retaining the existing four exclusions. The default Node 25 run failed in 18 files; sampled failures reproduced on main. CI uses Node 22.

  • Passed settings-binding parity, playback fixtures, local-path checks, and diff whitespace checks.

  • Full make test-go did not pass. Jellyfin compatibility and proxy passed a serial package rerun. All 35 remaining playback probe failures reproduced on main. The transcode-node download-tracking timing test failed in the package run but passed in isolation on both this branch and main.

  • Review follow-up: reproduced both pending-seek bugs before fixing them. All 42 focused player/settings tests, TypeScript, ESLint, formatting, and diff whitespace checks pass after the fix. Rejected local and room requests preserve the skip origin; accepted room requests accumulate without seeking locally before the room command.

Risks

Native clients require their follow-up implementations. Browser-owned fullscreen controls may not dispatch configurable Media Session actions. On older or unreachable servers, video uses the contract defaults and audiobooks retain browser-local preferences; server writes stay capability-gated.

Live native-fullscreen and two-browser synchronization checks were not performed. Profile changes, settings refresh, and import failures were covered by automated tests.

Checklist

  • I read and can explain the complete diff.
  • This pull request addresses one concern.

AI Disclosure

  • Harness: OpenAI Codex desktop; the author's Claude harness was not supplied.
  • Tool(s): OpenAI Codex, Claude, and CodeRabbit (PR review).
  • Model(s): gpt-6-astra (Codex); the exact Claude model identifier was not supplied and is not inferred here.
  • Involvement: AI-assisted implementation, UI work, tests, and review.
  • Adversarial review: Claude reviewed and revised the implementation, as reported by the author. Codex reviewed the complete feature diff and exercised settings and playback edge cases. Reviews found repeated skips losing increments during reanchoring and missing callers after making seekIntervals required. Both were fixed and verified with regression tests and TypeScript. Full-suite failures and baseline comparisons are recorded above.

Summary by CodeRabbit

  • New Features

    • Added configurable rewind and fast-forward intervals for video and audiobooks.
    • Playback settings support profile-saved interval choices, with browser-local audiobook values available for import.
    • Keyboard, on-screen, touch, and media-session controls use the configured intervals.
    • Added searchable playback settings with clearer saving, default, and error states.
  • Bug Fixes

    • Improved consecutive seeking after scrubbing so skip actions remain anchored to the pending seek position.
    • Skip controls now respect media duration boundaries, including when duration is unknown.

📝 Walkthrough

Walkthrough

Revision 9 adds four profile-scoped seek interval settings for video and audiobooks. The web app resolves these settings, supports legacy audiobook import, and applies configured intervals across playback controls, keyboard shortcuts, media-session actions, and transport APIs.

Changes

Configurable seek interval contract

Layer / File(s) Summary
Settings contract and conformance
contracts/settings/v1/*, internal/settingskeys/keys.go, internal/api/handlers/settings_seek_intervals_test.go, web/src/lib/settingsContract.ts, web/src/lib/settingsConformance.json, docs/settings-api.md
Revision 9 defines four profile-scoped enum settings with 5–90 second values, defaults of 10 and 30 seconds, profile fallback behavior, API validation, and client documentation.

Shared preference resolution

Layer / File(s) Summary
Shared preference resolution and legacy import
web/src/lib/seekIntervals.ts, web/src/hooks/queries/seekPreferences.ts, web/src/pages/audiobooks/player/useAudiobookPrefs.ts, web/src/hooks/queries/seekPreferences.test.tsx, web/src/pages/audiobooks/player/useAudiobookPrefs.test.ts
The web app resolves all four settings through one shared hook, validates choices, isolates profiles, falls back to browser storage when needed, and imports legacy audiobook values per direction.

Settings UI

Layer / File(s) Summary
Settings screens and audiobook preference controls
web/src/pages/settings/PlaybackSettings.tsx, web/src/pages/SettingsLayout.tsx, web/src/pages/audiobooks/player/PlayerSettingsMenu.tsx, web/src/pages/audiobooks/player/playerTestUtils.ts, web/src/pages/audiobooks/player/PlayerSettingsMenu.test.tsx, web/src/pages/settings/PlaybackSettings.test.tsx
Playback settings and the audiobook menu render profile or browser-local intervals, disable controls during discovery and saves, show errors, and report partial legacy imports.

Video playback pipeline

Layer / File(s) Summary
Video playback skip pipeline
web/src/player/*, web/src/playback/*, web/src/player/utils/skipTarget.ts, web/src/player/hooks/useMediaSkipHandlers.ts, web/src/player/components/*
Video playback receives resolved intervals and routes controls, keyboard input, touch gestures, media-session actions, and transport methods through a shared clamped skip implementation.

Audiobook playback integration

Layer / File(s) Summary
Audiobook playback integration
web/src/pages/audiobooks/player/MiniBar.tsx, web/src/pages/audiobooks/player/NowListening.tsx, web/src/pages/audiobooks/player/useAudiobookKeyboardShortcuts.ts
Audiobook seek bars and keyboard shortcuts use the resolved back and forward intervals.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to 40fd8

This change adds profile-specific video and audiobook seek intervals across playback controls. No current merge-blocking risk is identified.

- Around line 856-858: Update the seek handling around handlePlayerSeek so that
when requestTransport("seek", ...) returns ok: true, it stores the requested
target in both pendingSeekTimeRef.current and pendingSeekTime before performing
the seek; leave pending state unchanged for rejected room requests or local
seeks.
- Line 766: Update performPlayerSeek so pendingSeekTimeRef.current is assigned
only after canSeekAnywhere, seekable-range, and onReanchorSeek validation
succeeds in the accepted local-seek and reanchor branches. Leave existing
pending state unchanged when validation rejects the target, and keep the Watch
Together requestTransport path separate.
