🐛 Camera orientation not working to barcode

[Ferreiraguihh]

What's happening?

Basically, I'm using a device like a tablet, and I can't change the orientation of the component, I'm trying to use barcode, I know that in the 'react-native-camera' library, if I implement a rotate -90deg it works.

Reproduceable Code

const { onCodeScanned } = props;
  const device = useCameraDevice('back');
  const cameraRef = useRef<Camera>(null);

  const codeScanner = useCodeScanner({
    codeTypes: ['ean-13', 'upc-a'],
    onCodeScanned,
  });

  if (!device) {
    return null;
  }

<View>
<Camera
          ref={cameraRef}
          device={device}
          style={StyleSheet.absoluteFill}
          isActive={true}
          codeScanner={codeScanner}
          resizeMode="cover"
        />
</View>

Relevant log output

Can you reproduce this issue in the VisionCamera Example app?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

Guten Tag, Hans here! 🍻

It sounds like you are having trouble with camera orientation for barcode scanning. However, I noticed you did not include any relevant log output, which is important for diagnosing the issue.

Please provide logs from adb logcat when you run your app. This will help mrousavy to better understand what’s going wrong. Also, make sure to double-check that you tested this in the VisionCamera Example app, as mentioned.

If you continue to have troubles, feel free to update this issue with the necessary details! Thank you for your understanding, and don’t forget to support the project by sponsoring if you find it helpful!

Note: If you think I made a mistake, please ping @mrousavy to take a look.

@Ferreiraguihh my apologies for going off-topic but could you please give me a brief idea about how do you implement the scanning within the square reticle's bounds. It used to work in RNVC 2 for me but in 4.6.3, I get different frame sizes and unable to implement the same.

Hi @gyanbhartip did you manage to figure this out?
In my case, I'm using the frame parameter in onCodeScanned to figure out the scanning area, but it always returns landscape dimensions even though I'm previewing in portrait mode. I'd expect frame would always be the same as the preview size.

[gyanbhartip]

@jrizmal I've not been able to figure the "scanning within the reticle bounds" issue.
But the frame orientation is not the same as your preview orientation.
refer: the official docs on the Frame orientaion

Also for me the frame dimensions is restricted to 640x480 while the sensor format reports a rotation of landscape-left.
