Hi,
I had also some issues on windows with qmlglsrc , but it was a while ago. Code is outdated, and I need to reactivate the project.
Anyway I will take a look at it in the next days and maybe post a patch if successful.
On Linux (ubuntu with gnome shell) it worked without problems.
Regards,
Roland

Hi,
I'm trying to use qmlglsrc <https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good/html/gst-plugins-good-plugins-qmlglsrc.html> on Windows 10.
I've built it successfully without any issues (Qt 5.12.4 MSVC 2017 64bit).
But when I run grabqml <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/tree/master/tests/examples/qt/qmlsrc> example, I get these errors:

Can someone confirm that it works on some other platform?
Has anyone managed to get it working on Windows?
Thanks,
