1.2.9

Fixed

• Removed obsolete --record-audio flag (invalid on scrcpy 4.x; caused launch failures when record audio was enabled)
• Added required --video-source=camera for all camera-intent mirror paths
• Fixed device list refresh that could mark all known devices offline after a successful ADB poll
• Session recording no longer mutates the global auto-record display setting
• Session record/audio/camera overrides now survive intentional scrcpy restarts (merge before kill; preserve on exit)
• Quick-action process stop/kill routed through shared cross-platform terminate helpers
• Camera button active state synced via store and camera-exit events
• Encoding bitrate mode (VBR/CBR) UI marked unsupported (no scrcpy 4.x CLI mapping); localized strings for all languages

Added

• Shared pure buildScrcpyArgs module with unit tests (npm run test:args)
• Per-device session override helpers (sessionOverrides) with restart-order tests
• Project AGENTS.md (contributor rules for scrcpy args, settings vs session, process lifecycle)
