Running the standard example qmlsink in Qt6

Application Development
21

It looks like I will have to compile the qml plugin from source using meson without cerbero, as I need debug mode.

Maybe a good alternative would be using glimagesink and setting it to win id, which you can get from Qt.

Set Win ID:

gst_video_overlay_set_window_handle(GST_VIDEO_OVERLAY(sink), xwinid);

Get Win ID:

auto winId = videoWidgetContainer->videoWidget->winId();

Just for additional information my videoWidget is of class QWidget.
This works fine for me without any problems, might be worth a try.

Then file a bug report to Qt.

@Marcel323 I have the same problem like you. But changing debug to release sometimes work sometimes I am getting not installed error. Can you find the source of the problem. What can I make to solve that issue?
I used cerbero and When I inspect I can see the gstqml6 plugin.
