           Summary: Memory leak in videowidgettest.cpp
    Classification: Platform
           Product: GStreamer
           Version: 1.13.x
                OS: Linux
            Status: NEW
          Severity: normal

Hi

qt-gstreamer\tests\manual\videowidgettest.cpp


VideoWidgetTest::VideoWidgetTest(QWidget *parent, Qt::WindowFlags f)
    : QWidget(parent, f)
{
    m_ui.setupUi(this);

    QButtonGroup *group = new QButtonGroup(this);
    group->addButton(m_ui.playingButton, QGst::StatePlaying);
    group->addButton(m_ui.pausedButton, QGst::StatePaused);
    group->addButton(m_ui.readyButton, QGst::StateReady);
    group->addButton(m_ui.nullButton, QGst::StateNull);
    connect(group, SIGNAL(buttonClicked(int)), SLOT(onButtonClicked(int)));

    m_pipeline = QGst::Pipeline::create();
    m_src = QGst::ElementFactory::make("videotestsrc");

    if (!m_src) {
        throw std::runtime_error("Unable to create a videotestsrc");
    }

    m_pipeline->add(m_src);
}



Here when m_src is not created , then we should free the group element memory.

if (!m_src) {
        delete group;
        throw std::runtime_error("Unable to create a videotestsrc");
    }
