QR code reader in SAPUI5 app

I want to implement a SAPUI5 web application in SAP Web IDE that can scann OR codes with the phone camera. I've tried using some JavaScript libraries like WebCodeCamJS, jsQR, but none of them worked for me (I mean that even the camera does not recognize the QR code or the camera does not open). I also tried with the sap.ndc.BarcodeScanner which works from Fiori Client, but it's not a reliable solution for me. I also read about Cordova plugin, but my app is web, not mobile.

Have anyone any idea how could I achieve that? Any solution is welcome. Thanks.
