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/core/core.hpp>
#include <opencv/cv.h>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
cv::Mat img;
cv::VideoCapture cap("video.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?
