It's actually the whole media player that is mirrored including the (hidden by default) controls. |

Looks like the library is doing a css transformation to flip the camera based on MediaStream api https://github.com/nimiq/qr-scanner/blob/master/src/qr-scanner.ts#L366 https://github.com/nimiq/qr-scanner/blob/abcfe1bce2703721408d8ce7ebde94a359998506/src/qr-scanner.ts#L877 https://github.com/nimiq/qr-scanner/blob/abcfe1bce2703721408d8ce7ebde94a359998506/src/qr-scanner.ts#L935 Also, the worker implementation is using URL.createObjectURL which is not present in every browser. I'm going to move to another implementation, probably https://github.com/cozmo/jsQR |
