1. create a new Qt project with module Phonon
...
2. Add some codes in mainwindow.h & mainwindow.cpp
--- mainwindow.h ---
class MainWindow : public QMainWindow {
:
private:
Ui::MainWindow *ui;
QString m_mediaFile;
Phonon::VideoPlayer *player;};
--- mainwindow.cpp ---
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
player = new Phonon::VideoPlayer(Phonon::VideoCategory, this);
/// TODO: shall be a smart way to resize the playback area
player->move(0,63);
player->resize(width(), height()-63);
}
void MainWindow::on_action_Open_triggered()
{
QStringList filters;
filters << "Image files (*.mpg *.avi)"
<< "Any files (*)";
QFileDialog dialog(this);
dialog.setNameFilters(filters);
if (dialog.exec())
{
QStringList fileNames;
fileNames = dialog.selectedFiles();
m_mediaFile = fileNames.at(0);
setWindowTitle(m_mediaFile);
/// Load media file.
player->load(Phonon::MediaSource(m_mediaFile));
player->play();
}
}
...
The simple program can play video, mp3 and jpeg.
[] video : rmvb, mpg, vob ...
[] image : jpg ...[] music : mp3 ...
