Qt GUI overlay on camera input

Wed Dec 21, 2016 9:51 am

Hi,
I am looking to read video from the camera 1920x1080 30hz and display on the HDMI output.
( pycamera preview can achieve this this using minimal cpu intervention )

I then want to over lay a Qt GUI with a transparency colour key.

I have seen solutions using opencv but this required a lot of cpu intervention.

Is it possible to hardware blend the camera video and Qt Gui using a colour key?

If custom programming is required that is ok.

Thanks,
Louis
