<![CDATA[Issue in QT5 QML application for displaying video using GStreamerr]]>Hi Team,

We are developing a video playback application using Qt 5.6.3 on Processor Renesas RZG2N and PACKAGE VLP3.0.5

We are trying to display GStreamer test video in a QML application window. However, the video is not displaying in the window also it is not showing any errors.

Screenshot from 2024-01-11 15-03-51.png

Below is the sample application we are trying to play.

https://github.com/GStreamer/gst-plugins-good/tree/1.16/tests/examples/qt/qmlsink

Could you please guide us what could be the issue that we are not seeing the video in the Qt window

Thanks & Regards,

Rohini

gst-launch-1.0 --version
Does this version support Wayland?

We are unable to figure out what exactly is the error here. Could you please give us any pointers in that direction.

Yeah we ill upgrade Qt.
Yes, we are using wayland

The below command works fine for us

gst-launch-1.0 -v videotestsrc ! waylandsink

Better to upgrade Qt to at least 5.15.2. Are you on Wayland?
