  on power events

Better video streaming

• Significantly improved stream quality and performance
• Video now decodes in a background thread, reducing UI lag
• Stream rotation is now correct (no longer tilted at 25°)
• Streams restart automatically when a new browser tab connects
• Fixed streaming on Safari

Bug fixes

• Disconnected headsets are now properly grayed out in the interface
• All players are correctly disconnected when stopping an experiment

For developers

ADB & Headset Management

• Refactored AdbManager into a proper manager + new HeadsetSetup class handling all device checks and application
  installation
• Auto-install of auto-adb and Oculus ADB tools on headsets
  • Zero interaction one - https://github.com/project-SIMPLE/adb-auto-enable
• Added installApk() support for future self-healing headset configuration
• OVR preferences and power settings (4-hour auto-off) now configurable from the platform
• System/secure settings exposed for headset setup
• Early detection of device → offline transitions in AdbManager

UPS Power Control

• New UpsManager with polling, reconnection logic, and graceful shutdown
• Reverse-engineered communication protocol for the APC Back-UPS BX2200MI
• Automatic 3-hour session shutdown timer integrated with UPS state
• Added shutdownAllHeadsets() on the AdbManager

Video Streaming (Scrcpy)

• Migrated video decoding to WebCodecs API (replacing previous approach)
• Moved WebCodecs decoder to a Web Worker for better performance
• Added backpressure handling to keep video stream clean and reduce artifacts
• Bumped Scrcpy to v3.1 and yume-chan libs to v1.0.0 (stream rotation now flat)
• Fixed bitrate: was wrongly set to 200bps instead of 8Mbps
• Fallback to MessagePort when ReadableStream transfer is unsupported (Safari fix)
• Streams now restart for every newly connecting client
• ReadableStream and decoder lifecycle management improved

Networking & WebSockets

• Migrated WebSocket layer to µWebSockets.js (faster, lighter, better payload compression)
• Added multicast DNS (mDNS) support — connect via simple.local: instead of static IPs
• Per-message compression enabled for player connections
• Unified sendMessageByWs() function in Monitor for cleaner message handling
• Fixed wsID forwarding in addEveryPlayer

Player Management

• Migrated PlayerManager to a Map<id, player> structure
• Fixed player disconnect/reconnect edge cases (ghost players when closing a simulation)
• Properly disconnect all players when stopping an experiment
• Fixed player ID mismatch between websocket ID and in-game Unity ID

Gamaless Mode

• Better handling of the GAMALESS mode in both backend (verbose warnings) and frontend (visual indicator)
• Prevents crashes when no VU is found in the configuration

Scanning & Setup Scripts

• scan_and_connect script reworked: faster scan (~2s vs 10s), verbose flag, better regex, admin-mode speedup
• PowerShell equivalent script added for Windows users
• IP address sanitization added to prevent copy-paste artifacts from breaking the config

Cleanup & Refactoring

• Removed the old demo package and unused components/pages
• Removed React.FC usage across components
• Reorganized dependencies (most devDependencies moved to prod)
• Package version bumped to 3.0.0
• Added GitHub issue templates

Full Changelog: 2.5...v3.0

Webplatform V2.5

What's new ?

• Features — user-facing

  • Automatic network/device discovery and more robust ADB connections: the platform now auto-scans the subnet, uses a more reliable connection flow (tango/AdbManager/evilscan), and avoids attempting USB streaming when inappropriate. (@RoiArthurB)
  • Better codec handling for streams: automatic codec selection with safer fallbacks (h265/h264), server-driven codec negotiation and client compatibility checks to reduce broken streams. (@RoiArthurB)
  • Improved streaming layout and rendering: overhauled streaming rendering to maximally and responsively size each headset stream; new dynamic layout logic for portrait/landscape and grid fitting. (@GuillaumeLeroy34)
  • More resilient scrcpy/video behavior: device-specific cropping, restart logic for crashed streams, and protections against duplicate/ghost streams so displays remain stable. (@RoiArthurB, @GuillaumeLeroy34)
  • Usability: clearer error message when GAMA is unreachable to help users quickly resolve the common “GAMA not started” problem. (@RoiArthurB)

• Fixes — stability / bug fixes

  • Fixes to avoid duplicate canvases/streams and to prevent restarting streams that have already exited. (@RoiArthurB, @GuillaumeLeroy34)
  • Stream sizing and canvas dimension fixes (solo screen, grid sizing, responsive tests). (@GuillaumeLeroy34)
  • Improved removal/cleanup logic for disconnected ADB clients (moved to reliable hooks / list change handling). (@RoiArthurB)
  • Rotating error logs and Windows scrcpy path fixes. (@RoiArthurB)

• Logging, observability and developer quality-of-life

  • Full logging rework: switched to logtape, added meta sinks and separate frontend logger; improved trace logs and categories to facilitate debugging. (@RoiArthurB, @GuillaumeLeroy34)
  • Several housekeeping commits: bumped libraries, updated tsconfig, reorganized backend, and cleaned many console.log leftovers by using the new logging pipeline. (@GuillaumeLeroy34, @RoiArthurB)

• Chores / infra / security

  • Dependency bumps and maintenance: uWS/qs/express/vite/lodash bumps, various compatibility adjustments for newer Node versions. (@RoiArthurB, @GuillaumeLeroy34)
  • .env and configuration improvements: ENV_GAMALESS, ENV_SCRCPY_FORCE_H265, default app host set to wildcard to ease local demos. (@RoiArthurB)
