Hello,
I couldn't find example how to generate binding for already compiled library. I tried using gradle-javacpp-android as example but I couldn't figure out how can I link my shared library.
I have 4 libraries for 4 architectures:

lib
|-arm64-v8a
    |-libtest_library.so
|-armeabi-v7a
    |-libtest_library.so
|-x86
    |-libtest_library.so
|-x86_64
    |-libtest_library.so

test.h

#ifndef UNTITLED1_TEST_H
#define UNTITLED1_TEST_H

class Test {
    int m_val;
public:
    Test();

    int get_val();
};

#endif //UNTITLED1_TEST_H

Hello

I try to run your example on Android 5.1.1 and when i click on Start button i get this error

@d-a-gerashenko
I am running streaming video in one thread and recording in another. when i close the streaming event. i would like to close the recording event as well. how to do i gracefully close video stream chunker operation in middle of execution (referring to streaming-chunker sample example). I am unable to call "fFmpegChunker.stop();" in time so video file not getting closed properly. Could you please guide me?

P.S.: this logic is working fine for live streaming

Hello,
I have been trying the example the example JavaCV-android-example but found that it doesn't work for Android version 10 or higher, the video file (.mp4) is not created when the recording is complete.

I'm kind of new to android development but I think the problem is occurring because FFmpegFrameRecorder needs to be passed an instance of FILE that is the .mp4 video file, however, in new versions of Android (10 or higher) the creation of files no longer works that way and the MediaStore API should be used.

private void initRecorder() {
        ffmpeg_link = new File(getBaseContext().getExternalFilesDir(null), "stream.mp4");
        Log.w(LOG_TAG, "init recorder");

        if(RECORD_LENGTH > 0) {
            imagesIndex = 0;
            images = new Frame[RECORD_LENGTH * frameRate];
            timestamps = new long[images.length];
            for(int i = 0; i < images.length; i++) {
                images[i] = new Frame(imageWidth, imageHeight, Frame.DEPTH_UBYTE, 2);
                timestamps[i] = -1;
            }
        } else if(yuvImage == null) {
            yuvImage = new Frame(imageWidth, imageHeight, Frame.DEPTH_UBYTE, 2);
            Log.i(LOG_TAG, "create yuvImage");
        }

        Log.i(LOG_TAG, "ffmpeg_url: " + ffmpeg_link.getAbsolutePath());
        recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);
        recorder.setFormat("mp4");
        recorder.setSampleRate(sampleAudioRateInHz);
        // Set in the surface changed method
        recorder.setFrameRate(frameRate);

        Log.i(LOG_TAG, "recorder initialize success");

        audioRecordRunnable = new AudioRecordRunnable();
        audioThread = new Thread(audioRecordRunnable);
        runAudioThread = true;
        Log.i(LOG_TAG, "recorder initialize success");
    }

So far I haven't been able to figure out how to fix this problem. Does someone know how to solve this problem?

Hi,

I wan't able to compile opencv-stiching-native with latest GraalVM 22.0. Is there a plan to support that?

Following is part of the errors I got. Do you have any idea what these errors are? Can they be fixed by configuring GraalVM?

Hello, i'm trying to implement in java deepdream notebook from python
https://github.com/google/deepdream/blob/master/dream.ipynb

in python there are code that generating mean.binaryproto from values.

mean = np.float32([104.0, 116.0, 122.0]), # ImageNet mean, training set

I have add a library java variant of Nyphy called Nd4j.

Tryed to generate the mean file with code bellow.

  `     
    String meanFile = caffeConfigRoot + "mean.binaryproto";
    
    double[] meanTrainingSet = {104.0, 116.0, 122.0};

    INDArray indArray = Nd4j.create(meanTrainingSet);

    try (DataOutputStream dos = new DataOutputStream(new FileOutputStream(new File(meanFile)))){

        Nd4j.write(indArray, dos);

    }`

And i'm getting the error.

[blob.cpp:496] Check failed: count_ == proto.data_size() (1 vs. 0)

in this piece of code

`

BlobProto blobProto = new BlobProto();

ReadProtoFromBinaryFileOrDie(meanFile, blobProto);

FloatBlob meanBlob = new FloatBlob();

meanBlob.FromProto(blobProto);

`

Maybe is there some code how to generate this mean file from java or the problem not in mean file and it correct.

Anyway I'm trying to find a solution but there are a few information about this. Any help would be appreciated. Thank you;

Hi, I am trying to load a pre-compiled dynamic library ( libabc.so ) which contains extern functions declared in header and cpp files. But I am getting error during compilation.

The header and CPP file are as below :
[ export.h ]
extern "C" {
void multiply(int a, float b);
}

[ export.cpp ]
#include "export.h"
#include < iostream >
using namespace std;
extern "C" {
void multiply (int a, float b) {
cout << "Hello-World\n";
}
}

I compiled them into a shared object : libabc.so and copied it inside the src/main/java/somepackage/* . ( I am using the sample demo given here : https://github.com/bytedeco/sample-projects/blob/master/javacpp-mvn-simple-demo/ )

I am trying to load the library from Java and call the methods as shown below :

package somepackage;

import org.bytedeco.javacpp.;
import org.bytedeco.javacpp.annotation.;

@platform(library="abc")
public class MultiplyDemo {

static {
    Loader.load();
}

public native void multiply(int a, float b);

public static void main(String[] args) {

MultiplyDemo mul = new MultiplyDemo();
    mul.multiply(123, 100f);
}    

}

I am getting the error :

Hi,
in onPreviewFrame call back the byte array I am receiving is huge because camera params is set to 1280 x 720. I cannot not change the camera parameters because my app is supposed to record a high def video in the background. Now the issue I am facing is I have to compress or scale byte array from onPreviewframe call back so that I can save it in byte buffer without any memory exceptions.

((ByteBuffer) yuvImage.image[0].position(0)).put(bytes)

If there is any possible to achieve it please advice.

Thanks.

Sir I used the rtmp url like rtmp://10.136.45.22:1935/livestream/myStream.mp4. When recorded the streaming video. I got the issue. How to recover Please solve this issue. I am checking in MarshMallow mobile.

Hello Dear Community!

I like your project very much, and I'd like to use it in my personal projects. I met your library accidentally. You should be known much more than you already are.

I cloned this project to my local computer. When I run command mvn clean install I got the following error:

Failed to execute goal org.bytedeco:javacpp:1.5.3:build (process-classes) on project javacpp-mvn-simple-demo: Failed to execute JavaCPP Builder

I updated version of org.bytedeco:javacpp:1.5.3 as you can see.

I created very simple project using your library. I managed to build it using command mvn clean install. However, I cannot run this simple app. When I use command mvn "-Dexec.args=-classpath %classpath pl.backlog.green.VideoMaker" -Dexec.executable=java exec:exec I get an error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: 'long org.opencv.imgcodecs.Imgcodecs.imread_0(java.lang.String, int)'

Of course it is very similirally when I use IntelliJ execution mechanism.

Any help will be appreciated.

Best regards
Doktor Ziel
(you can understand it like Doctor Gree)

One I push the "start" recording button, I got these errors on my logcat :
I didn't change anything on the code, error happens on RecordActivity l216 :

recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);

Hello.
I currently downloaded the source code and tried to modify it.
In class CvCameraPreview in javacv-android-recognition

"import static org.bytedeco.javacpp.avutil.AV_PIX_FMT_NV21;"

This line said cannot resolve symbol avutil.
How do I resolve this issue?

When I modify the class by extending Pointer, it gives error :

Why ?

hi,
I can compile this project on ubuntu, and the native run ok.

but When i add dependency to quarkus project, and it can't be compiled.

will you show me an example?

Hi! this project is really helpful, thanks for the efforts. But somehow the result isn't accurate, it is also authenticating otherwise persons. Would you pl like to guide me how to make it more reliable and secure.
Bundle of thanks in advance.

Hi, I download a sample project and have this exception, how to solve this problem or what is a possible reason that cause this problem? I did not found any working solution. My OS is Windows 10. Thanks.

Hi.
This demo is working fine. and it's really helpful for me.
But I m facing one problem while trying to recognize the face but if there is light in the background so it ll not recognize a face.

Update sample project , it uses version 1.3. So, some syntax are different

Its working nice if added with permission nice means 100% correct. but i cant find out that from where recorder is getting the Frames from preview and where is connection between them. thanx in anticipation.

initRecorder()

    images[i] = new Frame(imageWidth, imageHeight, Frame.DEPTH_UBYTE, 2); ? or somewhere else

recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);

    recorder.setFormat("mp4");
    recorder.setSampleRate(sampleAudioRateInHz);
    // Set in the surface changed method
    recorder.setFrameRate(frameRate);
    audioRecordRunnable = new AudioRecordRunnable();
    audioThread = new Thread(audioRecordRunnable);
    runAudioThread = true;

java.lang.OutOfMemoryError: Physical memory usage is too high: physicalBytes = 384M > maxPhysicalBytes = 384M

This example (line 52) is confusing because method cuModuleLoadData expects path to the .ptx file, not string with file itself which causes error 301 CUDA_ERROR_FILE_NOT_FOUND.
It took me a while to realize that it was a bug in the example and not in my code

panorama stitcher doesn't crop the result image to remove that black area

why the caffe .jar not support windows?can you compile a version that support all os?

Hi,
Iam getting this errror .Please let me know that how can i overcome this

W/System.err: org.bytedeco.javacv.FrameGrabber$Exception: avformat_open_input() error -2: Could not open input "/storage/emulated/0/media/v4.avi". (Has setFormat() been called?)

i test the android demo find a funny problem.

defaultConfig {
applicationId "com.lc.testjavacv"
minSdk 23
targetSdk 30
versionCode 1
versionName "1.0"
}

when the minSdk is 23，it always report INSTALL_FAILED_INVALID_APK error;
I change the minSdk to 21 ,it ok.
who could explain it?

Is there any way to reduce loading time of JavaCV, native libraries of OpenCV.

Hello. I looked into javacpp-mvn-simple-demo, and it already contains native function in java for cpp function. But javacpp also provides ability to generate class with such function for class which implemets InfoMapper.
I have to run such commands manually now:

mvn clean compile && cd target/classes \
&& java -jar ../../javacpp.jar test.GreeterConfig \
&& cp test/Greeter.java ../../src/main/java/test;

And only after it I can package project with javacpp plugin. Is there a way to not run such commands manually and do it by maven?

Could you please update JavaCV in Android sample to latest version? I tried to do it but the app got crash.

My run string: java -jar caffe-sample-classifier-all.jar deploy.prototxt bvlc_reference_caffenet.caffemodel imagenet_mean.binaryproto synset_words.txt cat.jpg

I am look at the caffe-sample-classifier-all.jar and it does not contain jnicaffe.so and openblas.so only libopencv.so libs

And one more problem maybe not on the topic. When I start gradle.bat for the second time in another directory, it can not create a caffe-sample-classifier-all.jar but creates caffe-sample-classifier.jar without libraries. gradlew build cant help too.

Could you help with these errors?

javacpp-android-gradle build failed on AndroidStudio 4.1

When I try to use opencv_face.FaceRecognizer faceRecognizer = createLBPHFaceRecognizer(); it give me error. Please tell me how i can use different method of face recognizer in this.

I have downloaded the last version of JavaCV-android-example, built it in Android Studio 1.5.1 and started on Samsung Galaxy S6 Edge with Android 5.1.1. I clicked "Start" button, then after ~30 seconds "Stop" button. After all output file size was 44 bytes. I suppose that it is some kind of metadata. I added more logs to RecordActivity: on recorder.record() and recorder.recordSample() calls. These methods were called many times as expected. But why no data were written to output file "stream.mp4"?

Hello, Thank you for the sample projects.

I am trying to include facial landmark detection (https://github.com/bytedeco/javacv-examples/tree/master/flandmark-demo) in the javacv-android-recognize example. Initially I thought it cannot file the landmark model file: flandmark.dat. So I copied it to the android device. However I still have an error with flandmark_init, below please see my function that loads the landmark model:

public static FLANDMARK_Model loadFLandmarkModel(Context context) throws IOException {

    String landmarkFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/flandmark_model.dat";
    Log.i(TAG, "Loaded cascade classifier from " + landmarkFile);

    FLANDMARK_Model model = flandmark_init(landmarkFile);

    if (model == null) {
        Log.i(TAG, "Failed to load landmark model");
        model = null;
    } else {
        Log.i(TAG, "Loaded cascade classifier from " + landmarkFile);
    }
    // delete the temporary directory

    return model;
}

I am wondering what could be the reason. Any help would be appreciated. Thank you very much in advance.

How do I resolve this issue?

I am working with code from https://github.com/bytedeco/sample-projects/blob/master/JavaCV-android-example/app/src/main/java/org/bytedeco/javacv_android_example/record/RecordActivity.java. Demo working fine

I want to use wowza.gocoder with FFmpeg so by only add wowza dependancy in app.gradle then demo application crash at run time as screenshot

here is my app.gradle file

above app Gradle working file except comment com.wowza.gocoder.
if I uncomment file and as use recording I got error run time as define above even if I done write any code related to wowza.gocoder.
