# F1 OpenViewer by npanu420

Official login, entitlement, and DRM (Widevine) playback in an Electron app. Authorized access only — no piracy.

📖 **Setup:** [docs/SETUP.md](docs/SETUP.md) — clone, configure `.env`, run in dev, build and sign.

🔐 **Build & signing:** [docs/BUILD_SIGNING.md](docs/BUILD_SIGNING.md) — code signing, Widevine VMP, certificates.

## What it does

- **Authorized access** — Sign in with your F1 TV account (email/password, token, or in-app browser login).
- **DRM playback** — Stream protected content via Widevine CDM in a compliant way.
- **No unauthorized content** — No keys, bypasses, or stream sharing.

### The cool part

- **Everything stays in sync, automatically** — In multiview, the main feed, onboards, and data channel are continuously locked to each other: the sync engine anchors on the race/world feed and keeps correcting the rest (seek if the drift is large, subtle playback-rate nudges if it's small), so onboards never quietly drift ahead or behind the race. If the world feed rebuffers, everything else automatically syncs instead of running away.
- **Live Timing synced to the video, not just running alongside it** — Standings, gaps, sector times, tyre stints, race control messages and team radio line up automatically with whatever moment you're watching in the replay, no manual alignment needed.
- **Resizable, savable multiview layouts** — Drag and resize the stream grid, save layouts you like, and reuse them; pop the whole multiview out into its own fullscreen window.
- **Live-edge playback** — Live sessions track the live edge instead of drifting behind like a plain HTML5 video.

## Live Timing

Live Timing opens in its own window next to a session replay and shows the same kind of data you'd see on the official timing screen: standings, gaps, sector times, tyre stints, race control messages and team radio clips.

It runs on a public F1 archive that has nothing to do with F1 TV or DRM, so it doesn't need you to be logged in at all. The only login in this app is still the one for video playback.

**VPN note (Windows):** Live Timing isn't georestricted, but its host blocks many VPN exit IPs at the WAF level. On Windows, the app fetches the archive via the system `curl.exe` instead of in-process, specifically so that a full-tunnel VPN (e.g. NordVPN) can split-tunnel by excluding just `curl.exe` — Live Timing then leaves on your real IP while everything else stays on the VPN. If your VPN client only supports app-based split-tunneling, add an exclusion rule for `C:\Windows\System32\curl.exe`.

Manual alignment used to be difficult because the archive and video clocks weren't synchronized. Now, the app automatically fetches the correct offset  when you start a session. If this lookup fails or a session is unsupported, you can still align them manually via the sync menu by selecting the lap shown on screen or nudging the offset.

## Tech stack

| Layer | Technology |
|---|---|
| Desktop shell / DRM | **Electron** (Castlabs fork for Widevine), CDM handling, IPC to avoid CORS |
| UI | **React + Vite** |
| Playback | **Shaka Player** — DASH/HLS and Widevine DRM |
| Data | Unofficial F1 TV APIs — login at `api.formula1.com`, catalog/playback via an in-house client (`electron/f1tvapi.js`, MIT) against f1tv.formula1.com |

---

## Requirements

- **Node.js** (LTS recommended)
- **Valid F1 TV subscription**
- **Windows or macOS** — both are supported for build and Widevine DRM playback (see [docs/SETUP.md](docs/SETUP.md) / [docs/BUILD_SIGNING.md](docs/BUILD_SIGNING.md) for the per-OS Widevine CDM path and signing steps). Other platforms may need manual CDM setup.

## Roadmap

1. **Login / Auth** (Milestone 1) — Done: login UI, session token in memory, network layer.
2. **Entitlement / Licenses** (Milestone 2) — Entitlement, asset/manifest selection, permissions and expiry.
3. **DRM playback** (Milestone 3) — End-to-end playback with real licenses.
4. **UI and UX improvements** — New UI and better UX
5. **Live Timing** — Live Timing support for replays, synced automatically to the video

## Disclaimer & Legal Notice

Please read carefully before using or contributing to this project.

This project is a strictly non-profit, educational, and open-source endeavor developed solely by a university student for academic research purposes. The primary goal of this software is to study modern desktop streaming architectures, hybrid web-desktop frameworks (Electron/React), and the secure implementation of Digital Rights Management (DRM) technologies.

- **No Piracy or Paywall Bypass** — This application does NOT provide free access to Formula 1 broadcasts. It is fundamentally impossible to watch any live or on-demand session without authenticating via a legally purchased, active, and valid F1 TV Pro or Premium subscription.
- **Strict DRM Compliance** — This client does not decrypt, rip, record, or bypass any video protection mechanisms. It utilizes Google's certified Widevine Content Decryption Module (CDM) to legally and securely request and play the encrypted video streams (DASH/HLS), exactly as the official web player does.
- **No Geoblocking or VPN Bypass** — This software does not alter or mask your location. The official F1 TV servers enforce all regional restrictions and blackout rules based on your network IP during the entitlement process.
- **Zero Commercial Intent** — This project is 100% free, open-source, and contains no advertisements, telemetry, or monetization schemes of any kind.
- **Trademarks and Copyright** — This is an unofficial, community-driven academic project. It is not affiliated with, endorsed by, or sponsored by Formula One Digital Media Limited, Formula One Management, or any of their partners. "F1", "FORMULA 1", "F1 TV", and related marks are registered trademarks of Formula One Licensing B.V. All rights to the broadcast content, data, and official branding remain the exclusive property of their respective owners.

If you represent Formula One Digital Media Limited and have any concerns regarding this educational project, please contact me directly, and I will promptly address them or remove the repository.

### AI Disclaimer

AI was used in this project for **repetitive code** (e.g. login flows and boilerplate) and, in particular, for **translating the application, READMEs and code comments into English** so that documentation and code are easier to understand for everyone. Core logic and architecture remain human-authored.
