主函数

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

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

    return a.exec();
}

函数实现头文件

#ifndef STUDYWIDGET_H
#define STUDYWIDGET_H

#include <QWidget>
#include <QImage>
#include <QTimer>     // 设置采集数据的间隔时间
#include <QMediaPlayer>
#include <QDebug>
#include <QDir>
#include <QVideoWidget>
namespace Ui {
    class StudyWidget;
}

class StudyWidget : public QWidget
{
    Q_OBJECT

public:
    explicit StudyWidget(QWidget *parent = 0);
    ~StudyWidget();
    void music();
    void video();
private:
    Ui::StudyWidget *ui;
};

#endif // STUDYWIDGET_H

 

函数实现cpp

#include "studywidget.h"
#include "ui_studywidget.h"


StudyWidget::StudyWidget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::StudyWidget)
{
    ui->setupUi(this);
}

StudyWidget::~StudyWidget()
{
    delete ui;
}
void StudyWidget::video()
{
    QMediaPlayer *myPlayer = new QMediaPlayer(this);
    QVideoWidget *video = new QVideoWidget(this);
    video->resize(1104, 622);
    myPlayer->setVideoOutput(video);
    myPlayer->setMedia(QUrl::fromLocalFile("/Users/ZX/Desktop/zx1/1.mp4"));
    myPlayer->play();
}
void StudyWidget::music()
{
    // 音乐播放
    QMediaPlayer *myPlayer = new QMediaPlayer;
    //    QString runPath = QCoreApplication::applicationDirPath();// 获取当前exe所在路径
    //    QString absDir  = runPath + "/1.wav";
    QString absDir = "/Users/ZX/Desktop/zx1/mysound/davichi.mp3";
    //    QString current = QDir::currentPath();
    //    QString absDir  = current.mid(0, current.size() - 6) + "/mysound/davichi.mp3";
    qDebug() << absDir;
    myPlayer->setMedia(QUrl::fromLocalFile(absDir));
    myPlayer->setVolume(80);
    myPlayer->play();
}
