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();
}
遵循此代码.您可以使用有效的窗口 id 将小部件嵌入到另一个小部件中.如何显示其他应用程序的输出视频在 Qt 中?您可以使用 qx11embedwidget 和 qx11embedwidgetcontainerQX11EmbedWidget 和 QX11EmbedContainer
follow this code . you can embed a widget inside another widget using a valid window id . How to show output video of other application in Qt? you can use the qx11embedwidget and qx11embedwidgetcontainer QX11EmbedWidget and QX11EmbedContainer
