I am new to embedded with Qt.
I have a Qml application, in which I am trying is to grab whenever a screen change occurs and this is time critical.
I tried using Qml grab function as well as QQuickRenderControl grab function.
Both on i.MX6Q device takes almost 2 seconds. While on PC it takes only ~50 ms.
The screen resolution which I display my screen is 1920x1080.
Board is Sabre i.MX6Q with Yocto krogoth.
It seems like opengl is slow than expected on a sabre board.
I would like to know if there is any way to grab the screen in a faster method, say in milli seconds.
Thanks in advance!
