Issue : In QT application - I have developed QT application on Linux/Wayland using GStreamer.
In that in one of scenario - I am doing camera preview using Gstreamer pipeline using QT on wayland display.
My pipeline got started successfully and preview is coming once. After stopping pipeline - again i am starting preview with some new settings. But pipeline got started successfully - But video is not displayed on Wayland.
In success logs gbm buffer received properly. I failure logs looks like gbm buffer is not received.
Attached is the success and failure logs of QT Wayland.
