使用 Qt 播放实时视频流

下面给出了使用 Qt 播放视频文件的代码.我想播放来自 IP 摄像机的实时视频流,而不是播放视频.另一种方法是在 Qt 中嵌入 VLC 播放器,并在此处提供了该项目的链接.问题是我不知道如何将播放器包含在 Qt 中.那么我该如何进行呢?

Given below is the code for playing a video file using Qt. Instead of playing the video I want to play a live video stream from an IP Camera. Another approach is to embed the VLC Player in Qt and a link for the project is provided here. The problem is I do not know how to include the player in Qt. So how do I proceed?

#include <QApplication>
#include <QtMultimediaWidgets/QVideoWidget>
#include <QtMultimedia/QMediaPlayer>
#include <QtMultimedia/QMediaPlaylist>
#include <QFile>
#include <QHBoxLayout>
#include "DemoPlayer.h"
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QWidget *widget=new QWidget;
    widget->resize(400,300);

    QMediaPlayer *player=new QMediaPlayer;
    QVideoWidget *vw= new QVideoWidget;
    QHBoxLayout *layout=new QHBoxLayout;

    layout->addWidget(vw);
    widget->setLayout(layout);
    player->setVideoOutput(vw);
    player->setMedia(QUrl::fromLocalFile("C:/Users/Administrator/Desktop/1minute.mp4"));
    player->play();
    widget->show();
    qDebug()<<player->availableMetaData()<<player->currentMedia().canonicalUrl();

    return a.exec();
}
