Unity 5.0.2f1 - Compile Errors in XCode

Hi,

We have purchased your unity plugin from the assets store and followed the instruction in the ReadMe.pdf however when compiling in XCode we are getting the following linker errors, could you please help?

call VideoCapture function on Android

To accelerate video capturing, I modified WebCamTextureToMatSample by using VideoCapture directly instead of using WebCamTexture.
It worked well on OSX, WIN, and iOS, but not on Android 6.
It just showed a black texture.

According to the old document below:
http://enoxsoftware.github.io/OpenCVForUnity/doc/html/class_open_c_v_for_unity_1_1_video_capture.html
it seems that VideoCapture is not supported for above Android 5.
However, I'm using the latest asset and there are no similar words in the latest document:
https://enoxsoftware.github.io/OpenCVForUnity/3.0.0/doc/html/class_open_c_v_for_unity_1_1_video_capture.html

I appreciate if someone know whether VideoCapture is supported or not for Android in the latest asset.

Capturing ROI Every Frame for CamShift Example.

How to capture the detected object either every frame or on command when using your CamShift example? I'm able to detect the particular object but not able to create images for each frame in which the object was detected and to only show the area that is detected.

Unable to get it working on Android 64bit architecture

Hi,
We've been using the DLib face tracker and OpenCV library successfully in the 32bit architecture. However, since google play store has mandated 64 bit architectures from 1st August onward, we need to build using the same.

However we are finding that it doesn't work on 64 bit devices. Unity doesn't throw any errors during building and the app even asks for permission to access the camera but then isn't able to capture/display video from the camera.

Update to 4.1.1.

Hi,
Could you please release a version with OpenCV 4.1.1?
There are some fixes that would be quite useful on some of the apps we are using OpenCV for Unity with (commercial version).
Thx

Black camera video with Vuforia 4 on Unity 4.6.5 built as iOS project

Hi, I have encountered a problem that my iOS app built from unity project which camera video was totally black on screen and the camera video source is from the ARCamera Prefab provided by Vuforia with version 4.2.3. and the unity project only contains the following libraries : Vuforia and OpenCVForUnity.
I have tested the iOS App with only Vuforia library and it can normally obtain the camera video but if I add OpenCVForUnity library into the project then the iOS app running on iPhone or iPad would become the situation mentioned above.
Because I saw there is a example that combine Vuforia and OpenCVForUnity on Unity 5, have you tested these setting on Unity 4.6 and it work normally as the same as Unity 5. If you have done this before, please tell me the build setting in XCode

Where is constant CV_CAP_PROP_POS_FRAMES?

I think this is a issue, but how about?

Opencvforunity and unity 2017

Opencvforunity: Creation of mat worked perfectly fine in Unity 5 series. Now, we are working on unity 2017.3 and now mat object of the desired size is not getting created.
for example: Mat img=new Mat(480,480,CvType.CV_8UC3);
if we check the size of Mat it returns 0 or Null.
Function: Utils.matToTexture2D(f8UC3,imgTexture);
We get the exception: "ArgumentException: The output Texture2D object has to be of the same size
OpenCVForUnity.Utils.matToTexture2D (OpenCVForUnity.Mat mat, UnityEngine.Texture2D texture2D, UnityEngine.Color32[] bufferColors) (at Assets/OpenCVForUnity/org/opencv/unity/Utils.cs:303)

WebTextureToMat on iOS iPad Air2 (maybe ARM64?)

I'm running the WebTextureToMat Sample just fine on my iPad mini and iPad 3 and 4, but when I try it on my new iPad Air2, it doesn't work. It just flashes the screen briefly and goes blue. This happens with all the WebCam samples except ComicFilter which just shows a black screen.

Using Unity 2018.4.3f1

Is there a reason that the SimpleBlobDetector class is not wrapped?

It looks like SimpleBlobDetector, that is part of the OpenCV 4.0.x package, is not in OpenCVforUnity. Is this intentional or could this be an oversight?

estimateRigidTransform not supported in ver 2.3.3

I need to use estimateRigidTransform but it's not in ver 2.3.3
I noticed it's in ver 2.3.2 https://enoxsoftware.github.io/OpenCVForUnity/3.0.0/doc/html/class_open_c_v_for_unity_1_1_video.html
How can I use this method?
Is there a new equivalent?

Please respond.
Thank you.

Videoio.CAP_PROP_FRAME_COUNT always returns 1 in iOS Build

I'm trying to get the value of CAP_PROP_FRAME_COUNT.
It always return 1 no matter what video I open.

In UnityEditor build it returns the correct value,
when I build for iOS it always return 1.

What could be the reason?

This is my code for reference:

VideoCapture cap = new VideoCapture();
cap.open(path);
int max_frames = (int)cap.get(Videoio.CAP_PROP_FRAME_COUNT);

Your reply would be appreciated.

Add opencv_contrib module cnn_3dobj

Some contents of opencv_contrib are already implemented in OpenCVForUnity. However, cnn_3dobj is missing. Is there a chance that this module will come to OpenCVForUnity as well?

Text module/namespace not available for UWP

I need to perform OCR text recognition on a HoloLens. So I'm building a UWP app with the HoloToolkit and the HoloLensCameraStream package, followed along with your HoloLens example scenes to ensure things were building and running, but then when it came time for me to start writing OCR code, I discovered all of the classes in org/opencv_contrib/text are surrounded by #if !UNITY_WSA_10_0 which means that entire namespace is inaccessible.

What's the reason for this? I commented out that #if statement on all 9 of the files currently in the text folder and everything appears to compile and export just fine.

If there's a specific reason for excluding the text detection module in UWP/WSA builds, I think you should provide documentation for which specific modules are available under which runtime platforms, which isn't something I've found and I purchased this plugin with the understanding that it fully supported UWP (as I had no reason to suspect "partial" support).

Otherwise, please add text/OCR support to UWP/WSA builds.

(iOS) IPA processing failed

Trying to create IPA with enterprise signature. It fails every time on Xcode 11.1 and OpenCV 2.3.7. Logs doesn't print anything interesting except:
/Applications/Xcode.app/Contents/Developer/usr/bin/ipatool exited with 1
Tried to disable bitcode from issue #40 - didn't help.

Xcode 10.3 works great though.

Possible bug in Converters.cs

Hi,

I have purchased this product off the Unity Asset Store and came across a possible bug in org.opencv.utils.Converters.cs

From the method starting on 637. It would seem that this block would always throw, because if you take line 639 and line 645, no matter what m is, it will throw. So in my source I commented out 639 and 640 to get passed it. Can you please let me know if my assumptions are correct?

Thank you.

637 public static void Mat_to_vector_vector_Point(Mat m, List<MatOfPoint> pts)
638        {
639      if (m != null)
640            m.ThrowIfDisposed();
641
642      if (pts == null)
643             throw new CvException("Output List can't be null");
644
645      if (m == null)
646           throw new CvException("Input Mat can't be null");

            List<Mat> mats = new List<Mat>(m.rows());
            Mat_to_vector_Mat(m, mats);
            foreach (Mat mi in mats)
            {
                MatOfPoint pt = new MatOfPoint(mi);
                pts.Add(pt);
                mi.release();
            }
            mats.Clear();
        }

OpenCVForUnity.Net, .MultiTrack and .MatOfRect2D seem to be missing from the main OpenCVForUnity

Hey,

I'm trying to compile the examples (mainly the MobileNet SSD, Caffe, Tensor stuff) from this repo (2.2.8) with the OpenCVForUnity i downloaded from the asset store (also says 2.2.8) and these three packages seem to be missing, i do seem them on the documentation page.

I also have to fix the return type of several methods to get it to compile (vs2017, unity 2017.3.1), but everything else seems to work.

ARUCO import class to Unity

Hi,

I am working with the ARUCO example that comes with the openCVforUnity plugin. I am trying to call the class Aruco.cs but I can't seems to figure out how the example knows the location of this file. At the top of the example it does not reference this file anywhere yet it is able to make function called from this file. I am not knew to programming but am knew to Unity and C#. Any direction would help.

Thanks!
