Webcam Video Capture

[Thà nh Viên Mới]

actually yes.. i have some problems with using OpenCV in my code.. this is what i've done so far..

mycamerawindow.cpp

#include "MyCameraWindow.h"
 
MyCameraWindow::MyCameraWindow(CvCapture *cam, QWidget *parent) : QWidget(parent) {
    camera = cam;
    QVBoxLayout *layout = new QVBoxLayout;
    cvwidget = new QOpenCVWidget(this);
    layout->addWidget(cvwidget);
    setLayout(layout);
    resize(500, 400);
 
    startTimer(100);  // 0.1-second timer
 }
 
void MyCameraWindow::timerEvent(QTimerEvent*) {
    IplImage *image=cvQueryFrame(camera);
    cvwidget->putImage(image);
}

#include "MyCameraWindow.h"

MyCameraWindow::MyCameraWindow(CvCapture *cam, QWidget *parent) : QWidget(parent) {
    camera = cam;
    QVBoxLayout *layout = new QVBoxLayout;
    cvwidget = new QOpenCVWidget(this);
    layout->addWidget(cvwidget);
    setLayout(layout);
    resize(500, 400);

    startTimer(100);  // 0.1-second timer
 }

void MyCameraWindow::timerEvent(QTimerEvent*) {
    IplImage *image=cvQueryFrame(camera);
    cvwidget->putImage(image);
}

i get this code from http://qt-apps.org/content/show.php/...?content=89995

btw thank you for the algorithm, now i'll try to implement it to my code.. but if you don't mind, may i send my project file to you ?

if you use your code, you cant record with audio, how to record video with audio use OpenCV ???
