CMake Project Problem With MediaPlayer and VideoWidget

DzCode

Hi everyone,

In QMake projet I have no problem about adding QMediaPlayer and QVideoWidget. However, If I try it in Cmake project I have got the warning below at runtime:

defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"

My widget is visible but does not play any audio or any video.
I have added the below sections to cmake:

find_package(Qt5 ${USED_QT_VERSION} REQUIRED COMPONENTS
    Core
    Widgets
    Svg
    Multimedia
    MultimediaWidgets
)
target_link_libraries(${PROJECT_NAME}
    WidgetsLib
    DataAccessLayer
    Qt5::Core
    Qt5::Widgets
    Qt5::Svg
    Qt5::Multimedia
    Qt5::MultimediaWidgets

)

Cpp code is like below:

QHBoxLayout *p_horizontal_layout = new QHBoxLayout(this);
    QMediaPlayer *p_media_player = new QMediaPlayer(this);
    QVideoWidget *p_video_widget = new QVideoWidget(this);
    m_p_frame = new QFrame(this);
    m_p_frame->setLayout(p_horizontal_layout);

    p_media_player->setMedia(QUrl::fromLocalFile("C:/........./url.mp4")); 
    p_media_player->setVideoOutput(p_video_widget);
    m_p_frame->setGeometry(0,40,200,400);
    p_video_widget->show();
    m_media_player_list << p_media_player;
    m_video_widget_list << p_video_widget;
    p_horizontal_layout->addWidget(p_video_widget);

Still I need a solution

@DzCode Could you try to add your cmakelists.txt following:

SET(QT_USE_QTMULTIMEDIA TRUE)
SET(QT_USE_QTMULTIMEDIAWIDGETS TRUE)
...
QT5_USE_MODULES (${EXECUTABLE_NAME} Multimedia MultimediaWidgets)

DzCode

@mehmety888 did not work

I still have the problem.

I have no problem about the Qt5.9, but I have a problem in Qt5.12
