How to embed a youtube video?-CodePudding

I'm trying to embed a youtube video in a QWebEngineView widget, however, the video is not playing and I'm getting this msg:

"Video indisponible Watch on YouTube"

I tried with different videos and in all I got the same error, I also tried setting some settings up like:

    QWebEngineView* view = new QWebEngineView();
    view->setHtml(R"(<iframe width="800" height="600" src="https://www.youtube.com/embed/TodEc77i4t4" title="Qt 6 - The Ultimate UX Development Platform" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>)");

    view->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::FullScreenSupportEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::AllowRunningInsecureContent, true);
    view->settings()->setAttribute(QWebEngineSettings::SpatialNavigationEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::JavascriptEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::JavascriptCanOpenWindows, true);

    view->show();

What I'm missing?

I didn't use HTML and I test this way and it shows me the Video:

I add this code in MainWindow:


    QWidget *wgt = new QWidget(this);
    QGridLayout *gridLayout = new QGridLayout(wgt);

    wgt->setStyleSheet(QString::fromUtf8("border: 1px solid black;\n"
                                          "border-radius: 25px;background-color:black;"));
    ui->centralwidget->layout()->addWidget(wgt);


    QWebEngineView* view = new QWebEngineView(wgt);
    view->setWindowTitle("Qt 6 - The Ultimate UX Development Platform");

    view->setUrl(QUrl("https://www.youtube.com/embed/TodEc77i4t4"));

    view->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::FullScreenSupportEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::AllowRunningInsecureContent, true);
    view->settings()->setAttribute(QWebEngineSettings::SpatialNavigationEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::JavascriptEnabled, true);
    view->settings()->setAttribute(QWebEngineSettings::JavascriptCanOpenWindows, true);

    wgt->layout()->addWidget(view);

This is the Result:

For Style your widget please look at Qt Style Sheets Reference, it's similar to CSS and you can use this.

for example, you can add this:

    view->setStyleSheet(QString::fromUtf8("border: 1px solid black;\n"
                                          "border-radius: 25px;"));

QWebEngineView object didn't get style so I add it inside the helper widget and add style to that.
