c++ - 如何嵌入 YouTube 视频？

Question

我正在尝试将 YouTube 视频嵌入到 QWebEngineView 小部件中，但是，视频未播放，我收到以下消息:

“在 YouTube 上观看视频”

我尝试了不同的视频，但都遇到了相同的错误，我还尝试设置一些设置，例如:

    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();

我缺少什么？

Answer 1

我没有使用HTML，我以这种方式进行测试，它向我显示了视频:

我在主窗口中添加此代码:

    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);

这是结果:

对于您的小部件的样式，请查看 Qt Style Sheets Reference ，它与CSS类似，你可以使用它。

例如，您可以添加以下内容:

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

QWebEngineView 对象没有获取样式，因此我将其添加到帮助器小部件中并向其添加样式。
