fix: Barcode-Scanner Kamera öffnet sich nicht auf Apple/iOS-Geräten#20
Conversation
Auf iOS/Safari gibt listVideoInputDevices() leere Labels und teils leere Gerätelisten zurück, bevor die Kamera-Berechtigung erteilt wurde. Der Code versuchte per deviceId die Kamera zu öffnen, was auf Apple- Geräten fehlschlug. Lösung: decodeFromConstraints mit facingMode 'environment' statt Device-Enumeration verwenden. Zusätzlich autoPlay-Attribut am Video- Element für iOS Safari Kompatibilität. https://claude.ai/code/session_0169CbohMRqddD1LjPg8FmXf
