ffmpeg build error ERROR: Xlib not found
centos 6 x86_64
Unstaisfield link error while running javacv on raspberry pi 2
I follow this installation as i need perticular version of opencv i.e 2.4.9
http://random-tinkering.rhcloud.com/?p=68
I ran the opencv example program successfully given on above link.
Then i tried to run sample javacv program provided on following link
https://github.com/bytedeco/javacv
i add necessary jar files and libopencv_java249.so file to the sample project
import static org.bytedeco.javacpp.opencv_core.;
import static org.bytedeco.javacpp.opencv_imgproc.;
import static org.bytedeco.javacpp.opencv_highgui.*;
public class Smoother {
public static void smooth(String filename) {
IplImage image = cvLoadImage(filename);
if (image != null) {
cvSmooth(image, image);
cvSaveImage(filename, image);
cvReleaseImage(image);
}
}
}
it ran successfully on ubuntu 14 but giving this error on raspbian

Openssl not found while compiling ffmpeg on linux x64
Using version 0.10 on Ubuntu Trusty. Everything works fine until ffmpeg/cppbuild.sh tries to compile ffmpeg, quitting with "ERROR: openssl not found". Any thoughts?
ffmpeg preset is linked against too recent GLIBC_2.17
And therefore it does not load on Ubuntu 12.04. Tried to compile it on my system but that leads to SIGSEGV. Runnable example is https://github.com/jjYBdx4IL/misc/blob/master/src/test/java/jjybdx4il/javacv/examples/FFmpegTest.java at https://github.com/jjYBdx4IL/misc/ .

Whether it is related to environmental issue or running isssue??
I am using Centos 6.7 with GLIBC_2.12.
Whether i need to upgrade glibc ??
tesseract - Couldn't load gnustl_static: findLibrary returned null - android
Hello!
First of all - I will mention that I am new to using JNI so my problem may be a bit noobish.
I am trying to get tesseract to work on Android. I am using a Windows machine to develop so I decided to use precompiled libs from maven as there would be probably a lot of problems with lack of needed dependency libs.
I am using Gradle so I have added in dependencies:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
// compile fileTree(dir: 'jniLibs', include: ['*.so'])
wearApp project(':wear')
compile 'com.android.support:appcompat-v7:21.0.3'
// compile 'com.google.android.gms:play-services:6.5.87'
compile 'com.octo.android.robospice:robospice:1.4.14'
compile 'com.octo.android.robospice:robospice-okhttp:1.4.14'
compile 'com.jakewharton:butterknife:6.1.0'
compile 'org.bytedeco.javacpp-presets:tesseract:3.03-rc1-0.10'
compile 'org.bytedeco.javacpp-presets:tesseract:3.03-rc1-0.10:android-arm'
compile 'org.bytedeco.javacpp-presets:leptonica:1.71-0.10:android-arm'
}
Everything seems fine, tesseract is being seen, lept as well, but then:

As a bit of background - I try to run the application and create a new TessBaseAPI() on a Samsung Galaxy S1 (old but gold) with Android 2.3.3.
As I was googling around for a solution I have found some page which makes me think:
- either the android-arm jars do not contain properly build .so files (with gnustl_static) or my Android device is weird and doesn't have that library. Can you share some thoughts?
Thank you in advance.
Best Regards

Tesseract example causes JVM to crash in libtesseract.so
I have this java-code from your example-page.
I set the TESSDATA_PREFIX=/usr/share/tesseract-ocr/tessdata to match my local ubuntu-installation of tesseract.
import org.bytedeco.javacpp.*;
import static org.bytedeco.javacpp.lept.*;
public class TesseractSample {
public static void main(String[] args) {
BytePointer outText;
tesseract.TessBaseAPI api = new tesseract.TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata path
if (api.Init(null, "eng") != 0) {
System.err.println("Could not initialize tesseract.");
System.exit(1);
}
// Open input image with leptonica library
PIX image = pixRead(args.length > 0 ? args[0] : TesseractSample.class.getResource("/newBoard.png").getFile());
api.SetImage(image);
// Get OCR result
outText = api.GetUTF8Text();
System.out.println("OCR output:\n" + outText.getString());
// Destroy used object and release memory
api.End();
outText.deallocate();
pixDestroy(image);
}
}It causes the JVM to crash.

Any idea, what is wrong?
I'm completely lost in c++-land ;-)
using gsl with shared libcblas instead of javacpp's provided libgslblas
Hi, thank you for this fantastic project. I imported the library, an it works.
I would like to use atlas blas implementation for the blas part of gsl. In c, that would mean changing the make file to link libcblas and/or atlas instead of libgslblas. However, javacpp provides the prepackaged build that ignores system's files and uses the one provided in a platform jar.
Is there a way to specify which (shared) libraries to use instead of the ones provided inside jars?
If I'd have to build javacpp's gsl manually, where should i change the libcblas setting?
FFmpegFrameGrabber.start() fails
For some reason, my program crashes when FrameGrabber.start() is invoked.
I'm not sure what I'm doing wrong, I'm new android programming. I've searched for similar cases. Haven't found one posted on the web yet which is similar to mine.
Any help would be greatly appreciated.
This is the code I've implemented.
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ffile);
//VideoView display = (VideoView)findViewById(R.id.videoView1);
Intent intent = getIntent();
FilePath = intent.getStringExtra("path");
//display.setVideoPath(FilePath);
FFmpegFrameGrabber vidcap = new FFmpegFrameGrabber(FilePath);
Log.i(camera.TAG, "inited");
try {
vidcap.start();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Once start() is invoked, exception is raised during runtime and the app crashes. The library:
- I extracted all the .so files from ffmpeg-arm-android.jar and opencv-arm-android.jar into libs/armeabi.
- Copied javacv and javacpp into libs/

Caffe preset for images classification
could I use the caffe presets for image classification?
Adding support for WebM VP8 & VP9 to ffmpeg
Hi all,
I've patched the ffmpeg/cppbuild.sh script to include support for libvpx (to encode WebM videos).
Here's the gist: https://gist.github.com/beligum/f4a46aac90b807aa6907
For now, it's only implemented for linux x64, since it's the only architecture I have access to. Sources are downloaded from the official Google repo.
Enabling compilation for other platforms should be trivial.
Feel free to post feedback, follow-up or suggestions.

Android specific opencv helper
The current code works in android but since some optional parts use awt and that triggers lots of misleading warnings and the debugger is set on hold for each awt import.
Probably would be possible either replace the helper with a version w/out the awt code or replace such code with android-specific one (Rect vs Rectangle and such).
Caffe preset for Android and Windows
Do you think will be possible to add preset for Caffe?
Failed to execute JavaCPP Builder: Could not parse "libavutil/avutil.h": File does not exist
Hi, @saudet ,
I run the commandline as README.md 's Build Instructions:
mvn install --projects ,opencv,ffmpeg
got the error on ubuntu15.04-server-64bit as below :
Failed to execute JavaCPP Builder: Could not parse "libavutil/avutil.h": File does not exist -> [Help 1]
And I fix it by
mvn install -Pandroid-arm -Dplatform.root=/home/pete/Downloads/android-ndk-r10c/ --projects ,opencv,ffmpeg
Maybe the README.md 's Build Instructions should enrich?

JavaCpp presets w/ ffmpeg compile issues
Hi,
I'm having trouble compiling the presets for ffmpeg. Specifically regarding how enums are parsed. I downloaded the latest ffmpeg headers and also javacpp presets source code from github. The generated code cannot compile looks like mostly because the enums are not parsed correctly. For example the following line in avutil.java:
public native @ByRef AVColorSpace colorspace();
public native AVFrame colorspace(AVColorSpace colorspace);
but there's no type for AVColorSpace, instead, here's the how AVColorSpace is parsed from the header file:
/** YUV colorspace type. */
/** enum AVColorSpace */
public static final int
AVCOL_SPC_RGB = 0,
/** also ITU-R BT1361 / IEC 61966-2-4 xvYCC709 / SMPTE RP177 Annex B */
AVCOL_SPC_BT709 = 1,
AVCOL_SPC_UNSPECIFIED = 2,
AVCOL_SPC_FCC = 4,
/** also ITU-R BT601-6 625 / ITU-R BT1358 625 / ITU-R BT1700 625 PAL & SECAM / IEC 61966-2-4 xvYCC601 */
AVCOL_SPC_BT470BG = 5,
/** also ITU-R BT601-6 525 / ITU-R BT1358 525 / ITU-R BT1700 NTSC / functionally identical to above */
AVCOL_SPC_SMPTE170M = 6,
AVCOL_SPC_SMPTE240M = 7,
/** Used by Dirac / VC-2 and H.264 FRext, see ITU-T SG16 */
AVCOL_SPC_YCOCG = 8,
/** ITU-R BT2020 non-constant luminance system */
AVCOL_SPC_BT2020_NCL = 9,
/** ITU-R BT2020 constant luminance system */
AVCOL_SPC_BT2020_CL = 10,
/** Not part of ABI */
AVCOL_SPC_NB = 11;
public static final int AVCOL_SPC_YCGCO = AVCOL_SPC_YCOCG;
I also attached the full generated file at this post:
https://code.google.com/p/javacpp/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&groupby=&sort=&id=45

Building Javacpp-presets on Windows 64bit: short guide
Hello guys and girlz,
I've just managed to compile Javacpp-presets from source on Windows 7. This was a major hackage so I've decided to write this short guide in order to save you a couple of days messing around with Windows and prevent some big frustrations. ๐ฅ
1. First of all, you'll need to install the following dependencies:
MSYS2: http://msys2.github.io
WARNING: please don't use MSYS from mingw.org because it's hopelessly obsolete and doesn't support 64bit targets!
Download the appropriate package for your system architecture, run it and choose the following installation path:
C:\msys64
After installation please follow the instructions given on the site in order to initialize the package manager pacman and update system packages.
Then you'll need to install tar because it's requiered but isn't installed by default. Open the MSYS2 console from "Start" menu and type the folowing command:
pacman -S tar
Windows Platform SDK: http://www.microsoft.com/en-us/download/details.aspx?id=8279
This one is for Windows 7. You may actually need another SDK if you're running another Windows version.
MingW-w64 compiler toolset: http://mingw-w64.yaxm.org/doku.php/download
Download the installer from the above-mentioned site, run it, choose the installation path to be
C:\mingw64
and architecture = x86_64, threading model = win32, exception handling = SEH and build revision = 2.
7zip decompression package from here: http://www.7-zip.org/download.html
Please ensure that 7zip executable has been properly installed to
C:\Program Files\7-Zip\7z.exe
Java 7 JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html
Please ensure that the downloaded JDK does correspond to your system architecture!
Install Maven from https://maven.apache.org/download.cgi and set it up as described here: https://maven.apache.org/guides/getting-started/windows-prerequisites.html
Make sure that the mvn --version command issued from the command line prints meaningful Maven version.
Now you'll need to add the following code to your Windows PATH:
C:\msys64\usr\bin;C:\mingw64\mingw64\bin
Now fire up the Windows SDK Command Prompt (sic!) and issue the following commands:
bash --version
g++ --version
If it works you're ready to proceed with the compilation.
You'll need to compile and install the parent project - Javacpp - first.
Then proceed with compilation of Javacpp-presets:
- download or clone the latest source code and extract it to said
javacpp-presets - open the Windows SDK Command Prompt (sic!) and issue the following command:
cd javacpp-presets
bash cppbuild.sh -platform windows-x86_64 install leptonica tesseract or whatever else
If you'll forget to launch Windows SDK Command Prompt you'll get TARGET_CPU: unbound variable error!
If everything went well during the previous step, build the Java part as follows:
mvn install --project .,leptonica,tesseract
Don't forget the dot in the beginning of the projects list!
Have fun and keep on smiling! ๐

ffmpeg 2.3 avcodec dll depends on swresample dll
Due to a dll dependency, swresample must be loaded prior to any reference to avcodec, otherwise an UnsatisfiedLinkError is thrown.
To resolve this, the avcodec.java preset should inherit swresample as well as avutil.
This affects ffmpeg 2.3 but not 2.2.1.

How to improve the accuracy of points detected ?
Somebody knows how I can improve to become points found more accuracy ?
For Example in example here,
the pre-processing of image is just convert image to grayscale
There is something more that you do for sharing with us ?
I did cvEqualizeHist(gray, gray); and reduce specks from image:
cvMorphologyEx(gray, gray, null, null, CV_CAP_OPENNI, 1);
I tried to applied Gabor Filter but the accuracy of points wasn't good.
Where are CvPoint and CvScalar constructors?
In many places in my project I used similar lines:
CvScalar scalar=new CvScalar(0,1,2,3);
CvPoint point = new CvPoint(0,0)
then I changed library imports from com.googlecode. .... to org.bytedeco.javacpp. ...
(and library version from 0.7 to 0.8)
Now, although I use in my project this lines:
import org.bytedeco.javacpp.opencv_core.CvScalar;
import org.bytedeco.javacpp.opencv_core.CvPoint;
I don't see proper constructors (and generally class:
public static class CvScalar extends Pointer{..}).
Am I missed something or they shouldn't be avaible in ver. 0.8?
use -Djava.library.path shared libs resolution mechanism by default?
The proposal is to make the advanced library-in-a-jar handling optional (via sys prop) and off by default.
Example to run tests using the java.library.path property:
https://github.com/jjYBdx4IL/javacpp-presets/blob/master/tests/pom.xml
Java daemons usually use that solution too: wrapper scripts determine architecture and point -Djava.library.path to the correct location.
Linux distro cross-test results
I have implemented simple tests that are checking whether the Libs generated on Debian Squeeze can be loaded on newer Ubuntu/Debian OSes. I'm also parsing and printing out the dynamic sections of the libraries there.
The log files (and results) have the format testlog.$project.$buildos.$testos.log and can be found there:
https://github.com/jjYBdx4IL/javacpp-presets
4 projects cannot be built because sources are not available or incomplete (flandmark depends on opencv, for example). These projects are listed in the allow_failure section of https://github.com/jjYBdx4IL/javacpp-presets/blob/develop/.travis.yml
Just FYI.
Add support for xfeatures2d module of OpenCV 3
Some of the algorithms previously available in javacpp-presets moved in OpenCV 3 to xfeatures2d module. Those include SIFT, SURF, and related.There are also some other interesting algorithms in xfeatures2d module, like DAISY.
static Mat.createFrom() missing
On 05/03/2014 01:07 AM,
Well, I guess nevermind. Looks like it works if I give the opencv_core.Mat constructor the width, height, and type:
opencv_core.Mat mm = new opencv_core.Mat(matFace.rows(), matFace.cols(), matFace.type());It would be nice if I didn't need to provide those--pretty sure the OpenCV java bindings don't require that when using copyTo(). But not a big deal.
There's Mat.createFrom() that should do what you need:
https://github.com/bytedeco/javacpp-presets/blob/master/opencv/src/main/java/org/bytedeco/javacpp/helper/opencv_core.java#L2300
But whoops, I forgot to put them static. I'll be fixing that.
If possible, please open an issue here (just copy/paste), thanks!
Linux support for FlyCapture
Hello,
I wonder why there is no linux version for flycap. We just got new PGRย cameras, and I am new to their API.
I would like to implement the linux wrapper at least for the flea USB 3, if you have any advices I would be glad.
Cheers,
Jeremy.
Troubles with Tesseract/Leptonica presets
Hello,
first of all - thank you for bringing us this amazing project! We're using JavaCPP in our music recognition engine (www.audiveris.org) since 2012 for communicating with Tesseract OCR. For this purpose I've programmed an elegant interface manually, based on JavaCPP. It worked for us for several years until now.
For a couple of days I've tried to compile my old code with the current JavaCPP v0.10 and noticed that it doesn't compile anymore. While examining the new library code I've noticed several big changes. The biggest one was the introduction of an automatic system that does scan C++ headers and produce the appropriate Java interface.
I spent several days playing with the new JavaCPP library and its Tesseract presets in order to integrate it with my project. I must admit that I finally gave up on it after a while, not being able to get it work at all.
I would very appreciate it if someone could shed some light on the following issues I encountered with the Tesseract preset:
-
The documentation on manual installation says "Just put all the desired JAR files somewhere in your CLASSPATH". OK, it doesn't work out-of-box. My Ubuntu 14 and Netbeans 8 simply refuse to load the native libraries from supplied JARs. The native libraries have to be EXTRACTED first, otherwise the famous Unsatisfied Link exception is thrown. Is it the normal behaviour or am I missing something? Is there any dedicated LOAD method I forget to call?
-
I wasn't able to get Leptonica's pixReadMemTiff function work. It always returns "false" that indicates some internal error. Reading TIFF files does work though. My project relies heavily on the former method because we're constructing images on the fly. I have to debug the native library in order to be able to say more. Any suggestions on why it doesn't work?
-
Leptonica's native library is huge (2,3 MB) but Tesseract utilizes just a few methods, mostly PIX-related. The rest (over 90%) is never used but will be wastefully kept in memory. Is there any possibility to strip out unused code if the intended usage of Leptonica will be Tesseract alone?
-
Tesseract API supplies an iterator - ResultIterator - to be used for extraction of recognition results. This ResultIterator is inherited from LTRResultIterator which, in turn, is inherited from PageIterator. So it's basically possible to use this ResultIterator for accessing results at different levels like pages, words or single symbols.
In C++, it's possible to access PageIterator's method Empty() using ResultIterator instance:
ResultIterator rit = api.GetIterator();
if (rit.Empty())
continue;
It doesn't work in JavaCPP v0.10 because of the famous issue with the multiple inheritance in Java. From what I see in the generated code, ResultIterator extends LTRResultIterator which extends Pointer. Where is PageIterator?
It looks like I need to explicitely request PageIterator instance like this:
ResultIterator rit = api.GetIterator();
PageIterator pit = TessResultIteratorGetPageIterator(rit);
With the earlier versions of JavaCPP the C++ way has just worked, without any casts or extra accessors. Am I missing some important technical point here?
- LTRResultIterator::WordFontAttributes() uses several BOOL * parameters for returning font properties (monospaced, bold, italic etc.) My manual code utilizes BoolPointer for this purpose. The automatic code uses IntPointer though which is very inconvenient because client code has to do type conversion. Is there any reason for this change?
I kinda like the idea of automatic Java interface generation. It looks promising at saving us a lot of time. I would like to use this new feature in my project. That's why I'd highly appreciate any help on getting it up and running.
Thank you in advance!
Best regards
Max P.
MatofInt missing from opencv_core
I'm new to OpenCV and your JavaCV library as a whole so this might be naive but I have searched high and low and could not find MatOfInt class in opencv_core , I need it for some image effects and code where it is being used is as follows -
private final CvMat mKernel = new MatOfInt(
0, 0, 1, 0, 0,
0, 1, 2, 1, 0,
1, 2, -16, 2, 1,
0, 1, 2, 1, 0,
0, 0, 1, 0, 0
);
I'm thinking of using opencv4android sdk just for this class so if you can help in anyway then that would be great as I totally love the opencv+ffmpeg integration, i get with your javacv library and don't want to fiddle with other lib just for one class !

How to convert OpenCv code to JavaCv
Hello,
I am trying to write some video effects in android application. I got some sample code from OpenCv and converted it into javacv. Please let me know if I am going in right direction or not.
OpenCv :
public class RecolorRGVFilter implements Filter {
private final ArrayList<Mat> mChannels = new ArrayList<Mat>(4);
@Override
public void apply(final Mat src, final Mat dst) {
Core.split(src, mChannels);
final Mat r = mChannels.get(0);
final Mat g = mChannels.get(1);
final Mat b = mChannels.get(2);
// dst.b = min(dst.r, dst.g, dst.b)
Core.min(b, r, b);
Core.min(b, g, b);
Core.merge(mChannels, dst);
}
}
And in javaCv:
public class RecolorRGVFilter implements Filter {
private final ArrayList<CvArr> mChannels = new ArrayList<CvArr>(4);
@Override
public void apply(final CvArr src, final CvArr dst) {
// Core.split(src, mChannels);
cvSplit(src, mChannels.get(0), mChannels.get(1), mChannels.get(2),
mChannels.get(3));
final CvArr r = mChannels.get(0);
final CvArr g = mChannels.get(1);
final CvArr b = mChannels.get(2);
Mat r_mat = cvarrToMat(r);
Mat g_mat = cvarrToMat(g);
Mat b_mat = cvarrToMat(b);
// dst.b = min(dst.r, dst.g, dst.b)
min(b_mat, r_mat, b_mat);
min(b_mat, g_mat, b_mat);
// merge(mChannels, dst);
cvMerge(mChannels.get(0), mChannels.get(1), mChannels.get(2),
mChannels.get(3), dst);
}
}
My thinking behind this code is, I will covert every IplImage (video frame) of video to CvArr first, and then apply filter (shown above) and converting that new CvArr back to IplImage and save in new video. (but I don't know how to convert CvArr to IplImage and IplImage to CvArr).
Also, If not possible this way, Can we convert org.opencv.core.Mat to javacv CvMat and vice versa ?
I have spent a lot of time and this is very important for me. Please guide me
Mat.createFrom(BufferedImage ....) creates a Mat with wrong dimensions
Calling Mat.createFrom(BufferedImage..) for a 640x480 BufferedImage will create a 480x640 Mat.
The culprit might be this line in AbstractMat.copyFrom(..) :
create(image.getWidth(), image.getHeight(), CV_MAKETYPE(depth, numChannels));
super.copyFrom(image, gamma, flipChannels, roi);

presets version spec needed in parent
My tests submodule in javacpp-presets needs to reference the correct preset generated during the current build. Keeping the versions specs in sync manually within the same project does not make much sense.
Proposal: define the opencv, ffmpeg etc. artifact versions in a parent pom.xml. Or even use 0.9 instead of 2.4.9-0.9 -- that way one could simply write ${project.version}.
https://github.com/jjYBdx4IL/javacpp-presets/blob/master/tests/pom.xml :
<groupId>org.bytedeco.javacpp-presets</groupId>
<artifactId>opencv</artifactId>
<version>2.4.9-${project.parent.version}</version>
<classifier>${platform}</classifier>
<type>jar</type>
Much nicer would be:
<groupId>org.bytedeco.javacpp-presets</groupId>
<artifactId>opencv</artifactId>
<version>${project.version}</version>
<classifier>${platform}</classifier>
<type>jar</type>

Add dlib library to javacpp-presets

Using @StdVector
I'm trying to use http://docs.opencv.org/modules/objdetect/doc/cascade_classification.html#cascadeclassifier-detectmultiscale method
void CascadeClassifier::detectMultiScale(const Mat& image, vector<Rect>& objects, double scaleFactor=1.1, int minNeighbors=3, int flags=0, Size minSize=Size(), Size maxSize=Size())which is bound to this in javacpp-presets:
public native void detectMultiScale( @Const @ByRef Mat image,
@StdVector Rect objects,
double scaleFactor/*=1.1*/,
int minNeighbors/*=3*/, int flags/*=0*/,
@ByVal Size minSize/*=Size()*/,
@ByVal Size maxSize/*=Size()*/ );(I'm following the old http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html?highlight=detectmultiscale#running-sbt-samples and the new http://docs.opencv.org/trunk/doc/py_tutorials/py_objdetect/py_face_detection/py_face_detection.html#haar-cascade-detection-in-opencv)
So here is my code:
opencv_objdetect.CascadeClassifier faceCascade = new opencv_objdetect.CascadeClassifier(new BytePointer(IOUtils.toByteArray(FaceDetection.class.getResourceAsStream("haarcascade_frontalface_default.xml"))));
opencv_core.Mat img = opencv_highgui.imread("/tmp/photos/photo.JPG");
opencv_core.Mat grayImg = new opencv_core.Mat();
opencv_imgproc.cvtColor(img, grayImg, opencv_imgproc.COLOR_BGR2GRAY);
opencv_core.Rect faces = new opencv_core.Rect();
faceCascade.detectMultiScale(grayImg, faces, 1.3, 5, 0, new opencv_core.Size(), new opencv_core.Size());
And here I don't know what to do with my faces variable... because it is not a java Iterable nor it seems to be an array of any sort...
Could somebody tell me how to use the @StdVector mapping?

Possible that Highgui.imencode() is broken?
Hi all,
I've been playing around with the opencv javacpp preset for the last couple of hours and I think I've found a bug in the imencode() JNI wrapper.
It seems like the target buffer of the method never gets filled with the encoded image (it always stays empty). I've been testing on Ubuntu 14.04 64bit with version 2.4.9-0.9.
Eg. this yields an empty byte array and thus an empty file (filled with zeros)
Mat sourceImg = imread("/home/bram/lena.jpg");
Point cntr = new Point((int) Math.round(sourceImg.size().width() / 2.0), (int) Math.round(sourceImg.size().height() / 2.0));
Mat croppedImg = new Mat(sourceImg, new Rect(cntr.x()-50, cntr.y()-50, 100, 100));
int bufferSize = croppedImg.channels()*croppedImg.cols()*croppedImg.rows();
byte[] outputBuffer = new byte[bufferSize];
String ex = ".jpg";
boolean result = imencode(ex, croppedImg, outputBuffer);
FileOutputStream fileOuputStream = new FileOutputStream("/tmp/test"+ex);
fileOuputStream.write(outputBuffer);
fileOuputStream.close();I found this as a reference post that could be related: https://groups.google.com/forum/#!msg/android-opencv/SCC1gU2ood8/PZWNqAVhsdYJ
Can somebody please confirm?

FFMpeg / x264 compilation issue
I'm compiling with this command line:
./cppbuild.sh -platform linux-x86_64 install
It yields this:
install -m 644 libx264.a /home/mondain/workspace/github/javacpp-presets/ffmpeg/cppbuild/linux-x86_64/lib
ranlib /home/mondain/workspace/github/javacpp-presets/ffmpeg/cppbuild/linux-x86_64/lib/libx264.a
ERROR: libx264 not found
When I check the /home/mondain/workspace/github/javacpp-presets/ffmpeg/cppbuild/linux-x86_64/lib directory, the libx264.a file is there.
Manually compiled subset of JavaCPP Presets could not be accessed by Gradle
I'm experiencing an issue when I try to use leptonica + tessseract bindings, compiled from the latest trunk and installed into Maven local repository, from within Gradle. I've correctly added all required dependencies and pointed Gradle to MavenLocal repository.
Gradle does report the following error:
* What went wrong:
Could not resolve all dependencies for configuration ':compile'.
> Could not resolve org.bytedeco.javacpp-presets:leptonica:1.71-0.11.
Required by:

> Could not find org.bytedeco:javacpp-presets:0.11.
It looks like the parent POM is missing. I've looked into the local .m2 directory and the expected parent pom "javacpp-presets-0.11.pom" is, indeed, not there.
I'm using the following terminal commands in order to get everything built and installed:
bash cppbuild.sh -platform linux-x86 install leptonica tesseract
mvn install --projects leptonica,tesseract
Below the results:

Any ideas what's going wrong?
Thank you in advance!

opencv fails to access the headers on MacOSX
I get some of
[ERROR] Failed to execute JavaCPP Builder: Could not parse "opencv2/core/types_c.h": File does not exist
I checked and even made sure that the opencv/cppbuild/ dir contains the include and lib dirs.
What puzzles me a LOT is that checking the same code on linux seems working w/out any issue.

Wrapping CvCascadeClassifier for JavaCV classifier traning
Hi, I am wanting to train a cascade classifier using JavaCV. I am aware of the opencv_traincascade binary, however I would like to write this in Java code using the JavaCV library. Under the hood of traincascade, it uses the train() method in CvCascadeClassifier which is not available through JavaCV. Could a wrapper for the CvCascadeClassifer class be added to the opencv module?
Thanks.
FFmpeg binaries are built disabling some avdevices such as x11grab and avfoundation
From what I could gather ffmpeg builds automatically include x11grab and avfoundation devices (Trying to invoke the libs to replicate the following examples) and I'm wondering what in particular in the presets' build script makes it so those are not included? I noticed you guys build it with --disable-libxcb, is that what causes these components not to be included?
Support ffmpeg 2.4
The ffmpeg 2.3 branch is not actively maintained anymore. Can the ffmpeg preset be updated to use 2.4?
Tesseract fails on MacOS
I tried to build an eclipse project by mvn eclipse:eclipse -Dplatform.dependencies=true and then run the sample code tesseract code on MacOS from Eclipse with the error "Exception in thread "main" java.lang.UnsatisfiedLinkError: no jnitesseract in java.library.path"
I checked the dependencies and all platform jars are in the classpath. Then I tried to run the sample code using mvn package exec:java -Dexec.mainClass=BasicExample -Dexec.args="/open/tesseract-ocr/testing/phototest.tif" -Dplatform.dependencies=true, got the above error with no luck.
Error with class IntVectorVector in opencv_core.java
Hi,
I've copied the class IntVectorVector from the "opencv_core.java".
@Name("std::vector<std::vector<int> >") public static class IntVectorVector extends Pointer {
static { Loader.load(); }
/** Pointer cast constructor. Invokes {@link Pointer#Pointer(Pointer)}. */
public IntVectorVector(Pointer p) { super(p); }
public IntVectorVector(int[] ... array) { this(array.length); put(array); }
public IntVectorVector() { allocate(); }
public IntVectorVector(long n) { allocate(n); }
private native void allocate();
private native void allocate(@Cast("size_t") long n);

for (int j = 0; j < array[i].length; j++) {
put(i, j, array[i][j]);
}
}
return this;
}
}
However, there is an error when trying to compile with this class:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\string.h(

and
[

No user-defined-conversion operator available that can perform this conv

It shows that in the jnispider.cpp, there is an error of type casting in this command:
try {
VectorAdapter<VectorAdapter<int>> radapter(ptr->getVectorVectorInt());
rptr = radapter;
I dont understand why in this case the copied class is not working.
Could you show me please.
Thanks for your help.
