    Greetings,

    I am working on my own Wayland compositor and have been extending the official example in C++ known as minimal-cpp. However, I've encountered a problem: the compositor is unable to handle videos. From the information I've gathered online, I understand that the surfaces and sub-surfaces of the views should be handled automatically by the Qt framework, including any communication with OpenGL.

    There's another example in QML, also called minimal-qml. Interestingly, this example is capable of playing videos, something the C++ example can't do.

    I require this capability in the C++ example, so I'm left wondering why the minimal QML can handle video formats, while the minimal C++ cannot?
    What's more, the QML example supports both xdg and ivi surfaces, but if I disable xdg surface, it too becomes incapable of playing videos.

    I would greatly appreciate it if someone could assist me in understanding this issue, particularly in regards to handling video formats in the minimal C++ example.

    EDIT: To play the videos I am using this video widget from this example https://doc.qt.io/qt-6/qtmultimedia-videowidget-example.html. I tried this in qt version 6.5.2 and 6.7.2, same results for both .

    Thank you for your help in advance.
