    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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 ?
