- Status: computed from connection, presence, hold, relay, player facts; no setters (health writes and HealthStatus gone); pill, strip and source line read it; transitions go to the Notifier. - Notifier: noticeFor(event, context) with self presence, alone, window activity, playing and prefs; toasts for joins/leaves/returns/swaps/ Up next adds (with picture)/problems/chat, the rest logged; while sitting out only chat, nudges, starting, Up next (+ joins if chosen); alone no social notices; replayed lines logged; owns its toast timer. - System notifications (flutter_local_notifications: D-Bus on Linux, WinRT on Windows) when the window isn't focused; a click focuses it. - Toasts sit above the control bar and move with it. - Versions: each member's in the members card and avatar tooltip, the server's in the card header; the strip no longer shows it.

# Roadmap
|
||
|
||
Backlog and epics, in order. Done work lives in git history. Check an item
|
||
off by deleting it in the same commit as the code. Wire changes also edit
|
||
[PROTOCOL.md](PROTOCOL.md).
|
||
|
||
## Stabilisation (feature freeze)
|
||
|
||
No new systems or features until the app is stable on a proper
|
||
architecture. The next release is the restructure (1.3.0, or 2.0.0).
|
||
Problems are numbered; delete a line when its fix ships.
|
||
|
||
**Decisions** (agreed):
|
||
- D1 Presence: In (watching, full), Away (sat out: still in the server,
|
||
chat and chosen notifications, system notifications in the background,
|
||
not counted for the gate, ready counter or watched tracking), Gone
|
||
(disconnected, held in a grace period).
|
||
- D2 A joiner during playback does not pause it: they load in the
|
||
background and join already in sync (a pause also works, no pause is
|
||
cleaner).
|
||
- D3 Watched: at least as good as Jellyfin's own; a peek, skipping around
|
||
or a screenshot visit never counts. Basis: time present while it played.
|
||
- D4 Toasts above the control bar; toasts for joins/leaves, queue adds
|
||
(title, picture, who), swaps, problems; the rest in the activity log.
|
||
Chat pop-ups and their sound always on by default; only the unread badge
|
||
stays off the picture.
|
||
- D5 A reconnect resumes the same member within a grace period (~10 min).
|
||
- D6 The person passing a video on drops: others keep playing; on
|
||
reconnect the relay continues from where it was.
|
||
- D7 One controls model, two skins (done in 1.2.1-dev.1); uosc credited.
|
||
- D8 Always the latest version: automatic checks, a clear prompt (no
|
||
background download), never during playback.
|
||
- D9 Watching alone is a full standalone player: no social sounds or
|
||
prompts; social parts appear when others are there; no solo mode.
|
||
- D11 Login-only sites: error texts say which cookies were used.
|
||
|
||
**Problems:**
|
||
- P2 Viewers of a relay whose source is gone: mpv loops on failed seeks
|
||
past what the server buffered (viewer-side recovery, step 5).
|
||
- P7 Sat-out people get tracked as watched on Jellyfin.
|
||
- P9 The watched rule (position coverage) misses real watches (D3).
|
||
- P15 Commands reach a player mid-switch (`seek 90.0`, `event:5` errors).
|
||
- P17 Preload, warm relay and the fresh player per video are layered on
|
||
the player instead of being one media pipeline.
|
||
- P18 Bilibili "no video formats" with browser cookies set; the hint
|
||
wording misleads (D11).
|
||
- P22 Friends on different versions (D8). (P20 version visible and P21
|
||
update band: fixed in 1.2.1-dev.3; check the band in real use.)
|
||
- P23 Solo mode you enter and leave; going hosted loses the queue (D9).
|
||
- P24 The invite address list is unhelpful (shows the proxy's 198.18.x).
|
||
- P25 ssh to Gitea blocked through the proxy (pushes go over https).
|
||
- P28 Log noise: "Failed to create file cache"; an idle relay channel for
|
||
Jellyfin items everyone has an account for.
|
||
- P29 Relay start delay after a seek into an unbuffered part.
|
||
- P30 Shaders don't work on Windows. Fix in 1.2.1-dev.3 (list read-back
|
||
check; Windows hwdec `auto-copy`): a Windows user must confirm shaders
|
||
stay on and the EGL-surface error is gone.
|
||
- P31 Software rendering on a friend's Linux. 1.2.1-dev.3 logs it
|
||
(`mpv: render` lines); needs that friend's log, plus
|
||
`watch-together 2>&1 | grep VideoOutput` from a terminal if software.
|
||
- P32 The app freezes on exit, mostly reported on Windows. 1.2.1-dev.3:
|
||
orderly close, Linux `_exit` (0 crashes in 41 closes vs 10/10 before),
|
||
Windows normal close + TerminateProcess + watchdogs, untested on
|
||
Windows; if it still hangs: Event Viewer 1000/1002, a Task Manager dump,
|
||
the `close:` log lines.
|
||
- P33 No volume readout on wheel: likely fixed by the controls rework
|
||
(1.2.1-dev.1; a test covers both skins); confirm in real use.
|
||
- P34 Local anime folders are opened as plain files (no banner, names,
|
||
next episode, tracking); test library: the user's
|
||
`/mnt/torrents/Torrents/Binux/` (several shows and a movie).
|
||
|
||
**Restructure** (in order; reviewed against the code). Truth lives in
|
||
three places: the server (members, presence, gate, transport, queue incl.
|
||
the automatic continuation and countdown, relay state), the device
|
||
(client id, library and folders, match corrections, watch history,
|
||
settings, notification prefs, what this app is sourcing) and the
|
||
integrations (Jellyfin played/resume, AniList list).
|
||
3. Your server: one hub, listeners attached and detached without members
|
||
reconnecting (old isolate path kept until that's proven); Invite as a
|
||
value (filtered addresses, version gate from `/health.version`, an `fp`
|
||
field reserved for pinned certificates later); `SessionState` is
|
||
deleted here. Fixes P22 P23 P24; D9.
|
||
4. Library + Media identity: L1 local grouping (kinds, folder hints,
|
||
gaps, merge across folders) and L2 match (AniList/TVDB, art, names,
|
||
manual pin, cache); `MediaRef` in swap/queue media. Fixes P34.
|
||
5. Media pipeline + player host port: plan → resolve → open → ready,
|
||
commands queued during a switch, viewer-side recovery when a source
|
||
drops (no mpv seek loops, play what's buffered), resolver and source
|
||
chosen by capability; a Windows CI smoke job (start, open, close
|
||
within N s, no orphan process). Fixes P2 P15 P17 P18 P28 P29, P30–P32;
|
||
D11.
|
||
6. What's next (decides which/when, asks the pipeline to prepare;
|
||
continuation and countdown as server state, shared cancel) + Watch
|
||
tracking (time In from the presence history, device history, Jellyfin
|
||
now, AniList later). Fixes P7 P9; D3.
|
||
7. Release 1.3.0: publish the manifest (protocol 16 makes it a required
|
||
update for 1.2.x) and update the VPS dedicated server in the same
|
||
window; check a 1.2.x app gets a clear "update the app" message.
|
||
Composition root: an `AppGraph` built in `main.dart` only constructs and
|
||
disposes systems (no logic, no signals); systems get dependencies through
|
||
constructors, widgets through one `AppScope`; a test fails if the count
|
||
of `.instance` singletons grows (today: SessionState 94, AppSettings 51,
|
||
JellyfinAccounts 10, Profile 7).
|
||
Not in the restructure: P25 (ops).
|
||
|
||
|
||
**Agreed since:** the queue stays in memory (no server storage).
|
||
Transport: `wss://` preferred when a server offers it, `ws://` still
|
||
allowed (a cleartext exception on Android); it only carries sync.
|
||
Tests: many pin behaviour the restructure drops; each is tagged with the
|
||
step that rewrites it, and the safety-net scenarios (DEVELOPMENT "Tests")
|
||
must keep passing through every step. Open questions below are decided during the restructure.
|
||
How: incremental on `main` (one system extracted per step, every dev
|
||
build usable), `signals` plus constructor wiring through one composition
|
||
root (no new framework), dev builds `1.3.0-dev.N`, everyone moves to
|
||
proto 16 together at the 1.3.0 release. Rooms are out (no room id).
|
||
No Windows dev builds: restructure testing happens on Linux; Windows
|
||
friends stay on 1.2.x until the 1.3.0 release (Windows-only fixes like
|
||
P30 reach them then).
|
||
Left of the rename (app, binaries, archives and data folder are
|
||
Starsync): the repository (`Foxyz/sync_replay_project`) and with it the
|
||
manifest and asset URLs (a new manifest URL needs a release that reads
|
||
both first); the dedicated server's fallback folder
|
||
`~/.cache/watch-together`, the release token file
|
||
`~/.config/watch-together-release-token`, Jellyfin's client name "Watch
|
||
Together" (devices are listed under it) and `WatchTogetherApp`; dropping
|
||
the 1.2.x launchers from the archive once nobody updates from 1.2.x.
|
||
Left of step 1: Update and restart keeps the member `gone` for the
|
||
restarted app, but the app starts on Home (it does not rejoin by itself)
|
||
and does not remember what it was passing on, so a relay it served ends
|
||
with its grace unless it is put up again; worth doing only if updates
|
||
ever happen mid-session (D8 says never during playback).
|
||
Left of step 2: system notifications need a human check (Linux: the
|
||
notification shows and a click brings the window up, also on Wayland,
|
||
where focus may be refused without an activation token; Windows: toasts
|
||
from an unpackaged install, at 1.3.0). On Linux the notification carries
|
||
no `desktop-entry` hint (flutter_local_notifications_linux does not
|
||
export its hint types), so a shell may name it "starsync" from the
|
||
bundle rather than "Starsync".
|
||
|
||
**Open decisions:**
|
||
- Starting together: today someone has to stay unready so others can
|
||
join first. Ideas: a short "starting in 30 s, ready up" countdown;
|
||
waiting for everyone from the last session.
|
||
|
||
- Platform decision: "Desktop + mpv only" becomes "mpv only, desktop
|
||
first" if Android goes ahead.
|
||
- D10 was dropped on purpose (preload/warm relay/fresh player are folded
|
||
into step 6, not a separate decision).
|
||
|
||
### Protocol 16 (open parts)
|
||
|
||
Opened in step 1: [PROTOCOL.md](PROTOCOL.md) is proto 16 (version
|
||
ranges and the refusal frame, error codes and close codes, lasting members by client id with takeover and `seq`, grace and
|
||
`bye`, presence and `PresencePolicy`, `state.hold`, feed ids, `seq` and
|
||
replay, relay `sourceGone` and source resume, lasting `queue[].by`,
|
||
`auto` items and `cancel`, `media.ref`, `members[].app`/`caps`), server,
|
||
core and app. Still open on the wire, frozen at the 1.3.0 release:
|
||
- `state.advance` (step 6): the server starts the countdown when the
|
||
media finishes and an item is first, sets `queuePlay` at its end and
|
||
holds it while the item's performer or source is `gone`. Today it is
|
||
parsed and broadcast but never started; `auto` items and `cancel` are
|
||
live.
|
||
- `media.ref` producers (step 4); the server carries it already.
|
||
- `hello.client` optionally derived per server (HMAC of an install
|
||
secret and the dialled host:port).
|
||
- TLS: `/health.tls` is always false; `wss://` only with a CA-valid
|
||
certificate in 1.3.0, pinned self-signed via the Invite `fp` later.
|
||
- `err` code `rate`: reserved, nothing sends it.
|
||
|
||
## Backlog
|
||
|
||
1. **Auto-skip OP/ED** (undecided): who decides and how (shared for the
|
||
server, personal, per show) is open. Constraint: a skip is a seek and
|
||
seeks are shared, and only real ranges (segments, OP/ED chapters) should
|
||
ever be skipped.
|
||
|
||
2. **Files**: next episode from Files (by parsed episode, with the
|
||
countdown, and under Up next's "Continues with"). Later: tracking for
|
||
file series.
|
||
|
||
3. **yt-dlp follow-ups** (see ARCHITECTURE "yt-dlp"): check that the
|
||
bundled Windows libmpv has the ytdl hook (Lua) and plays `edl://` URLs
|
||
through media_kit; if not, resolve in the app and open the relay
|
||
tracks' formats. YouTube: yt-dlp wants a JS runtime (deno) for full
|
||
extraction. Formats that need yt-dlp's cookies.
|
||
- Live streams through the relay (today refused: the sync model needs a
|
||
fixed duration and seeking).
|
||
- `tool/relay_e2e.dart`: a two-track case (bytes and pieces) over a
|
||
shaped source link. Pieces on a slow source: a cold piece can take
|
||
longer than media_kit's 5 s `network-timeout`; if it does, fetch the
|
||
first pieces before setting `relay.live`.
|
||
- Pieces, unverified so far: the 403/410 re-resolve against a real
|
||
expiring HLS (signed segment URLs), HLS discontinuities / ad
|
||
splicing, Windows' bundled ffmpeg with extensionless piece URLs
|
||
(`p/<i>`; fine with ffmpeg 9 on Linux).
|
||
- Thumbnails and scrubbing previews of a relayed media with tracks
|
||
should open the video track's URL alone, not the EDL.
|
||
|
||
4. **AniList account**: sign in (OAuth via a localhost callback), "My list"
|
||
filter on the Schedule from the user's AniList lists. This is the
|
||
Schedule's personal tracking; AnimeFlow has no per-user follow.
|
||
|
||
5. **Ops**: Check shaders on Windows; run the relay e2e "the source drops
|
||
uncleanly and comes back" a few times under the full suite (its
|
||
predecessor failed about half the time there).
|
||
|
||
6. **Windows: first real use.** Check the rename at 1.3.0: a 1.2.x
|
||
install updates and restarts (`watch_together.exe`, a copy of
|
||
`starsync.exe`), the data in `%APPDATA%\foxyz\Starsync` came over from
|
||
`%APPDATA%\com.example\watch_together` and Documents, the next update
|
||
restarts `starsync.exe`. CI builds and publishes
|
||
`starsync-<ver>-windows-x64.zip` (libmpv bundled) and runs the
|
||
updater tests on NTFS; a friend has joined from it. Still unchecked:
|
||
fullscreen controls, hosting (firewall prompt), in-app update from one
|
||
release to the next. The rest of the desktop tests are not in CI.
|
||
|
||
7. **Relay follow-ups** (see ARCHITECTURE "Relay"). First real use: owner's
|
||
PC -> VPS -> friend, Jellyfin and a file. Then:
|
||
- Source takeover: when the source leaves, another member with an
|
||
account on that Jellyfin (or the same file: name, size, hash) takes
|
||
over instead of the buffer running dry.
|
||
- "Bob can't open this link — relay it?": offer the relay to whoever put
|
||
a direct link up when a viewer's player fails to open it.
|
||
- The host's own file as Up next's first item: it plays from `/m`
|
||
once up, so others open it cold (the warm relay covers every other
|
||
relayed item, see ARCHITECTURE "Relay"). The hosting app could hand
|
||
the server the item's path early and `/m` serve it under a `next/`
|
||
name until the swap.
|
||
- Research (before building anything): can stream URLs a member's
|
||
app resolved with yt-dlp (its cookies, its address) be fetched by
|
||
the server from another address? Per site: YouTube (its
|
||
`googlevideo` URLs carry the resolving IP), Bilibili, X, generic
|
||
HLS/DASH, others; and YouTube resolved by the server itself from a
|
||
VPS, with and without cookies. Decides whether a server-driven
|
||
fetch of member-resolved links (the member need not upload or stay)
|
||
is worth building.
|
||
|
||
8. **Jellyfin** (epic, below).
|
||
|
||
9. **Smaller items**
|
||
- Video output robustness: if media_kit's hardware path regresses to
|
||
software (see ARCHITECTURE, Media: render mode), vendor a
|
||
media_kit_video fix that builds the EGL display from GDK's native
|
||
display. The video freeze after GPU idle is not explained by this;
|
||
next suspect is media_kit's context switching on the raster thread
|
||
with NVIDIA.
|
||
- Link conveniences: a link swap in session updates the remembered media;
|
||
show the open link with an open-in-browser button.
|
||
- Time UI: remaining time, scrubber preview.
|
||
- mpv / mpv.net shortcut parity.
|
||
- Chaos suite: host drop 5 s / 30 s, viewer stall, 20-seek storm, long
|
||
outage with cache exhaustion (`tool/shaper.dart --kill-after`); assert no
|
||
OOM, no stuck session, drift recovers.
|
||
- Chat history pane (today: activity log only).
|
||
- Images in chat (paste a screenshot; server memory only): possible,
|
||
not wanted yet.
|
||
- HTTP: move the app's clients (Jellyfin, AniList, AnimeFlow, updater)
|
||
to dio from `fox_utils` when touching them, for retries/interceptors.
|
||
- TLS: document a reverse proxy in front of the server.
|
||
- Up next follow-ups (see ARCHITECTURE "Up next"): a whole season or
|
||
a pick list at once ("Add the rest of the season").
|
||
- Sidecar subtitles.
|
||
|
||
## Epic: Jellyfin
|
||
|
||
What is left (the rest is in [ARCHITECTURE.md](ARCHITECTURE.md), "Jellyfin
|
||
in a session"):
|
||
- Auto-advance cancel for everyone (the next episode and Up next): today
|
||
Cancel is per screen (the designated swapper's Cancel stops the swap; a
|
||
seek stops all). The wire has it (`queue` `cancel`, `state.advance`);
|
||
the app uses it in step 6.
|
||
- Sidecar (external) subtitle streams of Jellyfin items: only embedded
|
||
tracks are mapped to mpv today.
|
||
|
||
## Deferred
|
||
|
||
P2P, Android. Never: transcoding, web clients.
