  • 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 :

    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 ?
