Move extractEpisodeId() and sameEpisode() to shared episode-utils.js.
background.js imports via ES module. content.js (IIFE) receives injected
copy via build-extension.js marker replacement, eliminating duplication.
- Fixed episode guard regex to support Sxx:Exx title format (Jellyfin/Emby)
and any non-alphanumeric separator between season and episode numbers
- Migrated username, roomId, password, serverUrl, useCustomServer from
chrome.storage.sync to chrome.storage.local for per-device isolation,
preventing automatic cross-device room joins with duplicate names
- Added one-time migration from sync to local for existing users
- GET_VIDEO_STATE now returns allVideos[] with summary per video element
- Copy report shows markdown table when multiple videos on page
- Table includes: resolution, muted, paused, readyState, duration, and marks selected target
- Helps diagnose Prime Video scenarios where preview vs main video both exist
- findVideo() now scores all video elements by size + unmuted + duration
- Fixes Prime Video selecting 0x0 placeholder instead of actual player
- Fix history entries showing '?' by using h.action instead of h.event/h.type
- Update Prime Video status in TESTED_SERVICES.md to partial support
- Copy Logs button now generates full Markdown debug report (system, tab, connection, video, history, logs)
- Enhanced Dev tab with 20+ video state fields (network, dimensions, error, shadow DOM, platform detection)
- Platform auto-detection (YouTube, Netflix, Twitch, Prime Video, Disney+, Hulu, HBO, Vimeo, Dailymotion)
- 'No video found' diagnostic mode with hints
- Convert mockup from inline <span lang> to {{MOCK_*}} template vars (all 6 languages)
- New TwoPointZero branding: icons (16/32/48/96/128), favicons (PNG 16/32 + apple-touch + 192)
- Fix logo vertical centering via display:contents on picture wrappers
- Increase popup logo to 48px, website nav logo to 64px
- AVIF quality 70->80, speed 6->4, remove min 3KB threshold
- Add 32+96 icon sizes to manifest
- Remove amazon. from tab blacklist (unblocks Prime Video)
- Update TESTED_SERVICES.md: mark Prime Video as non-functional
- Update CONTRIBUTING.md with Copy Debug Report workflow
Streaming players (Emby, Jellyfin, etc.) perform frequent internal seeks
for buffering that are < 1s in magnitude. These were being relayed to
peers, causing brief video freezes every few minutes.
Fix:
- MIN_SEEK_DELTA = 3.0s: ignore seeks smaller than 3 seconds
- 800ms debounce: settle rapid-fire seeks (e.g. scrubbing) before relaying
- Programmatic seek suppression still takes priority via expectedEvents
- lastReportedSeekTime baseline updated on programmatic seeks too
Adds a new toggleable feature that detects episode transitions via
mediaTitle mutation (loadeddata/MutationObserver), pauses the video,
and waits for all room peers to load the same episode before
executing a coordinated Force Sync play at 0:00.
Protocol:
- Add EPISODE_LOBBY and EPISODE_READY events to shared/constants.js
- Add EPISODE_LOBBY_TIMEOUT (60s) constant
- Relay both new events in server/index.js
Content Script (content.js):
- Layered detection: loadeddata + MutationObserver src-change + heartbeat
- Debounced onEpisodeTransition() sends signal ONLY; no eager pause
- PAUSE_FOR_LOBBY handler pauses only after background confirms feature enabled
- startLobbyPoll() polls title match without premature pause for non-initiators
- checkAndReportLobbyReady() pauses and sends EPISODE_READY_LOCAL on match
- CONTENT_BOOT recovery for re-injection after hard navigation
Background (background.js):
- Episode lobby state persisted in chrome.storage.session with recovery
- EPISODE_CHANGED: checks setting, creates lobby, sends PAUSE_FOR_LOBBY to tab
- EPISODE_LOBBY/READY server event handlers with dedup logic
- 60s timeout cancels lobby (Option B) with Chrome failure notification
- Peer departure handled: removes from readyPeers, re-checks completion
- executeEpisodeLobby() reuses existing Force Sync pipeline at targetTime 0.0
- Lobby cleared on LEAVE_ROOM; status exposed in GET_STATUS
Popup:
- Auto-Sync Next Episode toggle in Settings tab (default: off, opt-in)
- Episode Lobby status card in Sync tab with peer readiness display
- LOBBY_UPDATE message handler for real-time UI updates
Bumps APP_VERSION and manifest to 1.2.0
