Display Gstreamer video in QML

[doon]

I try to use Gstreamer(not QtGstreamer or QtMultimedia) in QML(Qt Quick Controls Application), but I have a problem with video output. I tried default for GStreamer way to display video - set a window handle which I got from the QtQuick item, but of course without success.
So how can I display GStreamer video in QML? Maybe some experience of qtquickstreamer will help me?
Thanks.

There's a qmlvideosink in gst-plugins-bad, that can directly be
integrated into the QML scene graph.

There's an element called qmlglsink available from
https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/ext/qt/

There's also an example of it's usage here:

Thanks for the quick and simple answer, Sebastian and Matthew!
And are qmlvideosink and qmlglsink elements available for Windows, Linux, OS X, Android and iOS?
And how can I install them? Because I can't find them using gst-inspect-1.0.

They currently will work on Linux (X11), OS X, Android and iOS.  There's
currently no Windows support yet although that should be simple to add.

Currently you have to build gst-plugins-bad against a Qt >= 5.4
installation to be able to get access to qmlglsink.  On OS X and iOS
this is a little tricky as it requires changes to Qt's build files to
make it work.  All the other platforms work out of the box.

Is it possible to do it now manually?

Can you share a link which describes how can I do this? Because I used apt-get to install GStreamer.

Can you explain how can I do this or give a sample?

I think you missed my previous message, so do you have any suggestions about it?
By the way, can I use QtGstreamer on Windows(if I won't be able to use qmlglsink or qmlvideosink on Windows) for displaying video in QML?
Regards.

Honestly I don't remember seeing it and don't have the time to look for it.

It should be possible, I've never tried it.
