- config.xml author email -> support@screentinker.net - build-wgt.sh: stage app files only before signing (keeps README/build script out of the .wgt), auto-add the Tizen CLI to PATH if installed. - README: document the configured 'ScreenTinker' signing profile (self-signed author + default Tizen distributor) — installs on dev-mode TVs / emulator; production retail needs a Samsung distributor cert. Signed .wgt + the author cert are not committed (build artifact / secret).

# ScreenTinker — Tizen TV Player (`.wgt`)
|
|
|
|
A Samsung **Tizen TV / signage** web port of the ScreenTinker player. It speaks the
|
|
**exact same `/device` socket.io protocol** as the Android player, so a Tizen
|
|
display pairs and plays from the same dashboard with no server changes.
|
|
|
|
## What it does
|
|
- Enter a server URL → connects to `{server}/device` (socket.io v4).
|
|
- Registers, shows a **6-digit pairing code**; you claim it in the dashboard
|
|
(Devices → Pair a display). On `device:paired` it switches to playback.
|
|
- Reconnects automatically with a stored `device_id` + `device_token`.
|
|
- Renders **fullscreen single-zone** playlists, looping:
|
|
- **image** → shown for `duration_sec` (min 3s)
|
|
- **video** (`/api/content/{id}/file` or `remote_url`) → plays to end, then next; single item loops
|
|
- **YouTube** (`mime video/youtube`) → muted autoplay `<iframe>` embed
|
|
- **widget** → `<iframe>` of `{server}/api/widgets/{id}/render`
|
|
- Sends `device:heartbeat` every 15s (with best-effort Tizen telemetry).
|
|
- Keeps the screen awake (`tizen.power` / Samsung `appcommon` screensaver-off).
|
|

|
|
```
|
|
|
|
## Build
|
|
```bash
|
|
./build-wgt.sh # -> ScreenTinker.wgt
|
|
```
|
|
Without the Tizen CLI this is an **unsigned** `.wgt`.
|
|
|
|
## Deploy — two paths
|
|
|
|
### A) URL Launcher (easiest, no signing) — Samsung signage (SSSP)
|
|
No package needed. Host this folder on any web server (e.g. the ScreenTinker
|
|
server itself) and point the display's **URL Launcher** at `…/index.html`.
|
|
The TV runs it as a web app on boot. Best for Samsung B2B signage displays.
|
|
|
|
### B) Signed `.wgt` (installed app)
|
|
A signing profile is already set up on the build box (Tizen Studio CLI 6.1):
|
|
- **Profile `ScreenTinker`** = a self-signed **author** cert
|
|
(`~/tizen-studio-data/keystore/author/st_author.p12`) + the default Tizen
|
|
**distributor** cert. `./build-wgt.sh` auto-detects the CLI and signs with it,
|
|
producing a `.wgt` with `author-signature.xml` + `signature1.xml`.
|
|
- This installs on **developer-mode** Samsung TVs and the **Tizen emulator** —
|
|
the right path for a **self-hosted fleet you control** (enable Developer Mode
|
|
on each TV once: Apps → enter `12345` → set the host IP).
|
|
|
|
Install onto a dev-mode TV:
|
|
```bash
|
|
sdb connect <tv-ip>
|
|
tizen install -n ScreenTinker.wgt -t <tv-device>
|
|
```
|
|
|
|
**Production / retail (no developer mode):** re-sign with a Samsung **Partner**
|
|
or **Public** distributor certificate from the Tizen **Certificate Manager**
|
|
(free Samsung account; distributor cert tied to each TV's **DUID**), then
|
|
`./build-wgt.sh <thatProfile>`. The self-signed author cert is not committed (it
|
|
lives in `~/tizen-studio-data`, password `screentinker`).
|
|
|
|
## Validated (2026-06-09)
|
|
- **Protocol**: headless test against the live server passed end-to-end —
|
|
`register(pairing_code) → device:registered → pair → reconnect(device_id+token)
|
|
→ device:playlist-update(2 items) → GET /api/content/{id}/file = 200`.
|
|
- **Runtime**: loads + renders in Chromium with no JS errors (setup screen verified).
|
|
- Not yet on real Tizen hardware — needs signing + a TV (or URL Launcher).
|
|
|
|
## Not yet ported (Android player has these; fullscreen single-zone covers most signage)
|
|
Multi-zone layouts, video walls (`wall:sync`), screenshots, remote touch/control,
|
|
and self-OTA (Tizen apps update via Samsung's store / URL Launcher refresh, not the
|
|
Android `PackageInstaller` flow).
