LiveKit - Changelog - Bug reports - Roadmap
Native video conferencing client for La Suite Meet, powered by the LiveKit Rust SDK. Available on Android, iOS, and Desktop.
Status: Beta — Core functionality works end-to-end on all three platforms. Currently in closed beta on Android (Firebase) and iOS (TestFlight).
Want to join the beta? Contact mmaudet@linagora.com.
Left: iOS — Home screen | Right: Android — Active video call
- OIDC / ProConnect authentication with persistent sessions
- Room creation with 3 access levels (public, trusted, restricted)
- Waiting room / lobby management (admit/deny participants)
- Bidirectional audio and video on all platforms
- Real-time chat via LiveKit Stream API (
lk.chat) - On-device background blur and replacement (ONNX Runtime, no data leaves device)
- Animated emoji reactions via data channels
- Adaptive context modes (Office, Pedestrian, Car) with auto audio routing
- Bluetooth audio auto-routing with smart fallback on disconnect
- Hand raise with Meet interop
- Participant list with connection quality indicators
- Deep links:

4 Rust crates:
visio-core— Room lifecycle, auth (Meet API + OIDC session), chat, participants, media controls, hand raise, active speaker tracking, persistent settings, event system, lobby/waiting room, room access management, reactions, adaptive context enginevisio-video— Video frame rendering: I420 decode, renderer registry, platform-specific renderersvisio-ffi— UniFFI.udlbindings (control plane) + raw C FFI (video/audio zero-copy) + on-device background blur/replacement (ONNX Runtime selfie segmentation)visio-desktop— Tauri 2.x commands + cpal audio + AVFoundation camera capture (macOS)
Key design decisions:
- UniFFI for structured control plane (connect, toggle mic, send chat)
- Raw C FFI for video/audio (zero-copy I420 to native surfaces, PCM audio pull)
- No WebView for calls — fully native rendering on each platform
- Guest-first: no auth required, join via Meet URL
- Edge-first AI: background blur/replacement runs on-device via ONNX Runtime
- Rust nightly (edition 2024) —
rustup default nightly - Platform-specific requirements listed per section below
Prerequisites: Node.js 18+, Tauri CLI (cargo install tauri-cli@^2)
Linux only: Install system dependencies:

open ios/VisioMobile.xcodeprojVisio Mobile supports authentication via OpenID Connect (OIDC), compatible with ProConnect and any OIDC provider configured on the Meet server. Authentication is optional — anonymous users can still join public rooms via URL.
| Level | Description | Authentication required |
|---|---|---|
| Public | Anyone with the link can join immediately | No |
| Trusted | Authenticated users join directly; anonymous users enter waiting room | Host: Yes |
| Restricted | Invitation only — only explicitly added members can join | Yes (all) |
On-device background processing powered by ONNX Runtime selfie segmentation. All processing runs locally — no frames are sent to any server.
- Background blur — Gaussian blur applied to the background
- Background replacement — Replace with one of 8 built-in images
The app automatically adapts the interface based on physical context:
| Mode | Trigger | UI | Audio |
|---|---|---|---|
| Office | Default | Full video grid | Phone speaker/mic |
| Pedestrian | Walking detected | Single active speaker | Bluetooth headset |
| Car | Car Bluetooth detected | Audio-only, large buttons | Car Bluetooth |
6 languages supported: English, French, German, Spanish, Italian, Dutch.
Translations are stored as shared JSON files in i18n/. All platforms load from the same source of truth.
The app registers the visio:// URL scheme on all platforms.
Format: visio://host/slug — e.g., visio://meet.numerique.gouv.fr/abc-defg-hij

We're building the best open-source native video conferencing client. Native performance, edge-first AI, and zero compromise on privacy.
Most of the heavy engineering is handled by the incredible LiveKit team, allowing us to focus on delivering a great cross-platform experience. We favor quick, iterative releases and simplicity over complexity.
Our users come first. We're committed to making Visio Mobile as accessible and performant as proprietary solutions.
This project is available under the AGPL-3.0 license.
All features we develop will always remain open-source, and we are committed to contributing back to the LiveKit community whenever feasible.
Built with the awesome LiveKit Rust SDK. Visio Mobile is a native companion to La Suite Meet by DINUM.
We're also thankful to the teams behind UniFFI, Tauri, ONNX Runtime, and Jetpack Compose.
