【QT】视频播放

在网上没找到,在书上也没有。后来突然想直接在官网的类里面找Video 居然就有了。

http://qt-project.org/doc/qt-5/qmediaplayer.html的例子补充完整后就可以运行了。

注意pro文件中要添加内容,还有各种必要的头文件要添加。

 

开发环境Qt 5.3.2 

代码如下:

pro文件

QT       += core gui\
            multimedia\
            multimediawidgets


greaterThan(QT_MAJOR_VERSION, 4): QT += widgets\


TARGET = Video_Try
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

mainwindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QMediaPlayer>
#include <QMediaPlaylist>
#include <QVideoWidget>
#include <QUrl>

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    QMediaPlaylist * playlist;
    QMediaPlayer * player;
    QVideoWidget * videoWidget;

    MainWindow();
    ~MainWindow();
};

#endif // MAINWINDOW_H

mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow()
{
    playlist = new QMediaPlaylist;
    player = new QMediaPlayer;
    videoWidget = new QVideoWidget;

    setCentralWidget(videoWidget);

    playlist->addMedia(QUrl::fromLocalFile("D:/Users/Qt_project/Video_Try/3.avi"));
    playlist->setCurrentIndex(1);
    player->setPlaylist(playlist);
    player->setVideoOutput(videoWidget);

    videoWidget->show();
    player->play();
}

MainWindow::~MainWindow()
{

}

main

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec();
}
