QCamera video

[Yacinoben]

Hello

I am creating a program that allows you to take screenshots / videos using a webcam. I use it for the QCamera class.

I managed to do the screenshot , but for that of the video I do not know how.

camera.h

namespace Ui {
class Camera;
}

class Camera : public QWidget
{
Q_OBJECT
public:
explicit Camera(QWidget *parent = 0);
~Camera();
private slots:
void on_buttonVideoStop_clicked();
void captureCameraImage();
void captureCameraVideo();

private:
Ui::Camera *ui;

QCamera *camera;
QCameraViewfinder*cameraFinder;

QCameraImageCapture *cameraImageCapture;
QMediaRecorder *cameraVideoCapture;

QMenu *menuOption;
QAction *actionCameraStart;
QAction *actionCameraStop;
QAction *actionCaptureEcran;
QAction *actionCaptureVideo;
};

• camera.cpp

Camera::Camera(QWidget *parent) :
QWidget(parent),
ui(new Ui::Camera)
{
QVBoxLayout *layout =new QVBoxLayout;
ui->setupUi(this);

camera=new QCamera(this);
cameraFinder=new QCameraViewfinder(this);
cameraImageCapture=new QCameraImageCapture(camera,this);
cameraVideoCapture=new QMediaRecorder(camera);

camera->setViewfinder(cameraFinder);

menuOption=new QMenu("Option",this);
actionCameraStart=new QAction("Start",this);
 actionCameraStop=new QAction("Stop",this);
 actionCaptureEcran=new QAction("Capture D'ecran",this);
 actionCaptureVideo=new QAction("Capture Video",this);

 menuOption->addActions({actionCameraStart,actionCameraStop,actionCaptureEcran,actionCaptureVideo});
 ui->buttonOption->setMenu(menuOption);

 layout->addWidget(cameraFinder);
 ui->scollAffichageCamera->setLayout(layout);

 connect(actionCameraStart,&QAction::triggered,[&](){camera->start();});
 connect(actionCameraStop,&QAction::triggered,[&](){camera->stop();});
 connect(actionCaptureEcran,SIGNAL(triggered()),this,SLOT(captureCameraImage()));
  connect(actionCaptureVideo,SIGNAL(triggered()),this,SLOT(captureCameraVideo()));

}

Camera::~Camera()
{
delete ui;
}

void Camera::captureCameraImage()
{
QString filename=QFileDialog::getSaveFileName(this,"Capture","Capture","(*jpeg)");
if(filename.isEmpty())return;
cameraImageCapture->setCaptureDestination(QCameraImageCapture::CaptureToFile);
QImageEncoderSettings imageEncoderSettings;
imageEncoderSettings.setCodec("image/jpeg");
imageEncoderSettings.setResolution(1600,1200);
cameraImageCapture->setEncodingSettings(imageEncoderSettings);
camera->setCaptureMode(QCamera::CaptureStillImage);
camera->start();
camera->searchAndLock();
cameraImageCapture->capture(filename);
camera->unlock();

}
void Camera::captureCameraVideo()
{
QString fileName=QFileDialog::getSaveFileName(this,"Capture","Capture","(*mpeg2)");
if(fileName.isEmpty())return;
QVideoEncoderSettings videoEncoderSettings;
videoEncoderSettings.setCodec("video/mpeg2");
videoEncoderSettings.setQuality(QMultimedia::LowQuality);
videoEncoderSettings.setResolution(640,480);
cameraVideoCapture->setVideoSettings(videoEncoderSettings);
camera->setCaptureMode(QCamera::CaptureVideo);
cameraVideoCapture->setOutputLocation(QUrl::fromLocalFile(fileName));
cameraVideoCapture->record();
}
void Camera::on_buttonVideoStop_clicked()
{
cameraVideoCapture->stop();
}
Thank's
