Getting A signal 11 (SIGSEGV), code 2 (SEGV_ACCERR) when camera captures a QR code

[yousrasd]

What were you trying to do?

We are using react-native-vision-camera with vision-camera-code-scanner to capture QR codes.

We use the useScanBarcodes hook to detect QR codes. When testing our application, the app crashes whenever it tries to capture a QR code. When it captures normal text (containing no QR code), the camera continues working. However, whenever it finds a QR code in its viewport, it abruptly crashes. You can view this behaviour bellow:

iPhone devices are working fine. They are able to capture the QR code.

We are using ReactNative version 0.70.6 (we are not using the new architecture).

Reproducible Code

import React, {useEffect, useRef, useState } from 'react';
import { Linking, StyleSheet, View } from 'react-native';
  import {
  Camera,
 } from 'react-native-vision-camera';
import { BarcodeFormat, useScanBarcodes } from 'vision-camera-code-scanner';

const VisionCamera = ({ onRead, isCameraActive, externalStyle = {} }) => {
  const camera = useRef(null);
  const [backCamera, setBackCamera] = useState(undefined);
  const [qrCode, setQrCode] = useState(null);

  const [frameProcessor, barcodes] = useScanBarcodes([
    BarcodeFormat.QR_CODE,  
  ]);
 

  useEffect(() => {
    const getDevices = async () => {
      try {
        const devices = await Camera.getAvailableCameraDevices();
        setBackCamera(devices[0]);
        return devices;
      } catch (err) {
      }
    };
    getDevices();
  }, []);
 
  const onError =  (error) => {
    if (__DEV__) {
      console.log('Camera run time error', error);
    }
  };

  return (
    backCamera && isCameraActive && (
      <>
        <Camera
          photo={false}
          enableHighQualityPhotos={false}
          ref={camera}
          style={[styles.camera, styles.cameraStyle]}
          isActive={true}
          orientation="portrait"
          device={backCamera}
           frameProcessor={frameProcessor}
          frameProcessorFps={1}
          audio={false}
          onError={onError}
        />
      </>
    )
  );
};

What happened instead?

Whenever the camera detects a QR code, it crashes. I found the following stacktrace in Android Studio related to this crash.

Did you find any solution how to fix it? The same issue with:

• "react-native": "0.70.6",
• "react-native-vision-camera": "^2.15.2",
• "vision-camera-code-scanner": "^0.2.0",
• "react-native-reanimated": "^2.14.4",

[yousrasd]

@vrakovs-abc No, still havent found one

[vrakovs-abc]

This fork: https://github.com/jorgebrunetto/vision-camera-code-scanner fixed my issue.

[yousrasd]

@vrakovs-abc oh thats nice, will take a look

[alex-vasylchenko]

also got a similar error but only in production build Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 14227 (pool-46-thread-)

[alex-vasylchenko]

This fork: https://github.com/jorgebrunetto/vision-camera-code-scanner fixed my issue.

still the same error

[alex-vasylchenko]

@yousrasd did you manage to fix this problem?

[yousrasd]

@alex-vasylchenko unfortunately no

[alex-vasylchenko]

@yousrasd did you start using something else or are you still trying to fix this problem?

[yousrasd]

@alex-vasylchenko yes, started looking into https://github.com/teslamotors/react-native-camera-kit (instead of react-native-vision-camera)
