🐛 FATAL EXCEPTION: mrousavy/VisionCamera.video

What's happening?

When I exited the scanning page, a crash occurred

Reproduceable Code

let device = useCameraDevice('front');
  // 添加设备检查
  if (!device) {
    console.error('未找到相机设备');
    return null; // 或者返回一个占位符组件
  }
  const {hasPermission, requestPermission} = useCameraPermission();
  const isFocused = useIsFocused();
  const [isActive, setIsActive] = useState(false);
  const cameraRef = useRef<VisionCamera | null>(null);
  const [isForeground, setIsForeground] = useState(true);
  const targetFps = 5;
  const screenAspectRatio = 16 / 9;
  const format = useCameraFormat(device, [
    {fps: targetFps},
    {videoAspectRatio: screenAspectRatio},
    {photoAspectRatio: screenAspectRatio},
  ]);
  const codeScanner = useCodeScanner({
    codeTypes: ['qr'],
    onCodeScanned: codes => {
      console.log('Scanned codes:', codes);

      if (codes[0]?.value) {
        navigation.navigate('Index', {
          code: codes[0]?.value as string,
        });
      }
    },
  });

  const renderCamera = () => {
    return isActive && device ? (
      <Camera
        style={styles.absoluteFill}
        device={device}
        format={format}
        isActive={isActive}
        enableZoomGesture={false}
        ref={cameraRef}
        resizeMode="cover"
        exposure={0}
        onStarted={() => console.log('Camera started!')}
        onStopped={() => console.log('Camera stopped!')}
        photo={true}
        video={false}
        codeScanner={codeScanner}
      />
    ) : (
      <></>
    );
  };

Guten Tag, Hans here, 🍻

Thanks for reporting ze issue! It seems ze log you provided indicates a NullPointerException, which is likely related to ze camera image processing. One thing to note is that you mentioned you cannot reproduce this issue in ze Example app, which could suggest ze issue might be with your specific implementation or environment.

To better assist you, please make sure to check for any potential discrepancies in ze implementation compared to ze Example app. Additionally, if you encounter any more issues, ensure you attach ze logs from adb logcat for a deeper look into ze problem.

If you're finding value in this project, consider sponsoring mrousavy here to support further development.

Let's keep zis issue open for now!

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