  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • 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 :

    otool after macdeployqt output :

    /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 ?

  • Warning "i686-mingw32-pkg-config not found, library detection may fail" while cross compiling ffmpeg

    12 octobre 2015, par S B

    I get the following warning while trying to cross compile ffmpeg as below

    Configure ran fine but with the following warning

    How do I provide i686-mingw32-pkg-config to configure ?
