How to play youtube video on the ui

greencow

I would like to play the video from youtube but I couldn't make it. Can anyone please help !
Here are my code:

QT       += core gui multimedia multimediawidgets // this is added in the .pro

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

#include <QMediaPlayer>
#include <QVideoWidget>
#include <QDebug>

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

    QMediaPlayer *player = new QMediaPlayer;
        
    QMediaContent *mc=new QMediaContent(QUrl("https://www.youtube.com/watch?v=ksBjyegtBKE"));
    
    player->setMedia(*mc);
    
    
    player->setVolume(50);
    
    QVideoWidget *videoWidget = new QVideoWidget;
    
    videoWidget->resize(700,700);
    
    videoWidget->show();
    
    player->setVideoOutput(videoWidget);
    
    player->play();

    
    
    qDebug()<<player->availableMetaData()<<player->currentMedia().canonicalUrl();
    
    qDebug()<<player->errorString();
}

MainWindow::~MainWindow()
{
    delete ui;
}

These are the code in mainwindow.cpp

and I got an error

() QUrl("https://www.youtube.com/watch?v=ksBjyegtBKE")
""
DirectShowPlayerService::doRender: Unresolved error code 0x80040218 ()

How can I fix the problem or any other way to play the video ?

Thank you for helping !

@greencow said in How to play youtube video on the ui:

new QMediaContent(QUrl("https://www.youtube.com/watch?v=ksBjyegtBKE"));

the url doesn't provide a video stream, but the youtube HTML page of the video.

Take a look at this.
Youtube videos use RMTP streaming protocol.
