Hey adamgf

I tried to use your module and i am getting an error and it says "Execution failed for task ':react-native-opencv3:generateDebugBuildConfig'"
I have attached the screenshot of the console error.

Can you please help me resolve the issue.

Thanks in advance
Lochan :)

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
JSI_LIB
linked by target "expo-gl" in directory /Users/shenmingming/Desktop/App/FaceKey/node_modules/expo-gl-cpp/cpp

Steps to Reproduce -

1. Take fresh git clone of react-native-opencv3-tests repo
2. cd CvImageManipulations
3. npm install
4. react-native run-android

Behavior -

App launches successfully. But on clicking any of the buttons (Histogram, Canny, Sobel etc.), the app first hangs and then crashes. Nothing comes in the logs.
Device - Oneplus (Android 10)

Please note that this problem started happening only after November 22 and 23 changes. I had previously done the same steps on November 1 and the demo app was working flawlessly at that time.

can we read ArUco markers using this library ?

I didn't understand where are we providing the code to look for a circular shape. I would like to detect square shapes in image and is there any way to detect custom shapes that I can code in like triangles etc?

Hi there,
First of all thanks for creating this package!

I am trying to run one of the examples like the CvFaceDetection but I am getting a error from Xcode saying:
Reference to 'Ptr' is ambiguous (find screenshot attached).

Here are the steps to reproduce:

1. Download react-native-opencv3-tests
2. Nativate with the terminal to react-native-opencv3-tests-master/CvFaceDetection/
3. npm install
4. cd ios/
5. pod install
6. Open and run the Xcode workspace

Thanks and best regards
Nik

When I run "yarn", I faced following error.

npm ERR! code E404
npm ERR! 404 Not Found: [email protected]

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/jacky/.npm/_logs/2018-12-06T14_41_53_892Z-debug.log

so I removed yarn.lock, package-lock.json

and open the CvCameraPreview.xcworkspace file on xcode.
and then run "pod install" in ios folder.
I got this error

[!] CocoaPods could not find compatible versions for pod "RNOpencv3/CvCamera":
  In snapshot (Podfile.lock):
    RNOpencv3/CvCamera (from `../node_modules/react-native-opencv3/ios/RNOpencv3.podspec`)

  In Podfile:
    RNOpencv3/CvCamera (from `../node_modules/react-native-opencv3/ios/RNOpencv3.podspec`)

None of your spec sources contain a spec satisfying the dependency: `RNOpencv3/CvCamera (from `../node_modules/react-native-opencv3/ios/RNOpencv3.podspec`)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

please help me to run your example
Thank you.

Hello there,
How would we pause openCV engine on real time, show an Alert message within a button whether to "Exit" or "scan" to keep scanning faces?
As the screenshot attached shows

Hi, im recieving this error when I run pod install

So far react-native-opencv3-test/CvCameraPreview itself runs fine with no errors.

However, when I bring CvCameraPreview to my app as a new Screen, buttons gets disabled (Take Photo, switch video/image

I’ve installed its required packages: react-native-fs, react-native-opencv3 and react-native-video
However, I believe there's something else blocking/disabling Screen buttons to work. Switch Button to camera/video and Play button to TakePicture/RecordVideo are disabled in the screen.

Is there anything that must be amended/added within /ios/ directory (i.e. any dependency, library, etc)

Any idea?

Anyway, I’ll keep you posted

It’d be great to post this dialogue on GitHub

Best wishes,
I
