• Opencv ffmpeg : Video capture ("Filename.avi") crashes on a non development machine - MAC 10.8.2

  8 mars 2013, par Jerry

  I was trying to deploy a simple Qt Opencv Application, the following is the code :

  Qt : .pro file :

  QT       += core gui
  
  greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
  
  TARGET = opencvVideoTest
  
  TEMPLATE = app
  
  
  
  SOURCES += main.cpp\
  
      mainwindow.cpp
  
  
  
  HEADERS  += mainwindow.h
  
  
  
  FORMS    += mainwindow.ui
  
  
  
  INCLUDEPATH = -I/usr/local/include
  
  
  
  LIBS += -lm -lopencv_core -lopencv_highgui -lopencv_imgproc

  Mainwindow.cpp :

  #include "mainwindow.h"
  
  #include "ui_mainwindow.h"
  
  #include <opencv2></opencv2>core/core.hpp>
  
  #include <opencv></opencv>cv.h>
  
  #include <opencv2></opencv2>highgui/highgui.hpp>
  
  #include <opencv2></opencv2>imgproc/imgproc.hpp>
  
  
  
  
  
  MainWindow::MainWindow(QWidget *parent) :
  
      QMainWindow(parent),
  
      ui(new Ui::MainWindow)
  
  {
  
      ui->setupUi(this);
  
  
  
      cv::Mat img;
  
  
  
     cv::VideoCapture cap("BMWM5.avi");
  
  
  
     if(cap.isOpened()){
  
  
  
     for(;;){
  
         cap.read(img);
  
         cv::resize(img,img,cv::Size(604,480));
  
         cv::imshow("Opencv", img);
  
         cv::waitKey(33);
  
     }
  
     }
  
     else{
  
  
  
     }
  
  
  
  
  
  }
  
  
  
  MainWindow::~MainWindow()
  
  {
  
      delete ui;
  
  }

  The above snippet works fine on the development machine, which by the has Opencv 2.4.3, ffmpeg 1.1.2 & Qt 5.0.1. This what happens when I try to deploy, running the otool before using macdeployqt and the output :

  >   /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
  
   version 169.3.0)   /usr/local/opt/opencv/lib/libopencv_core.2.4.3.dylib
  
   (compatibility version 2.4.0, current version 2.4.3)

  >   /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current
  
    version 56.0.0)

  otool after macdeployqt output :

  /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)
  
      @executable_path/../Frameworks/libopencv_core.2.4.3.dylib (compatibility version 2.4.0, current version 2.4.3)

  /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)

  But after deploying it, when I try and run the app on the user's machine it crashes, no error reported either, the exact samething used to happen in Windows but when I copied the opencv_ffmpeg.dll into the exe folder it worked fine. I tried to use the same logic here and failed, then I manually addded each lib files of all the ffmpeg and its dependency into the project folder and still failed. Any other solution, please help ? I'm a newbie to mac dpeloyment. Am i missing or overlooked something ?

• Anomalie #3002 (Nouveau) : Boucle infinie dans ecrire/inc/rubriques.php function propager_les_sect...

  14 mai 2013, par Vince Vinet

  En référence à http://comments.gmane.org/gmane.comp.web.spip.devel/64252

  Dans le cas où une rubrique est son propre parent, la fonction boucle à l’infini.

  Raison :
  La query
  SELECT ...
  FROM spip_rubriques as A, spip_rubriques as R
  WHERE A.id_parent = R.id_rubrique AND (A.id_secteur <> R.id_secteur OR A.profondeur <> R.profondeur +1 )

  va toujours retourner les rangées qui sont leur propre parent.

  Ça incrémente non-stop la profondeur jusqu’au plafond de smallint et ça continue.

  Mon fix : ajouter A.id_rubrique <> R.id_rubrique dans le WHERE
