  • HTML5 audio and video support

    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 (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • 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

    otool after macdeployqt output :

    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

    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 ?
