Hi Shine,

I understood "running vision app single-camera demo" but didn't quite understand the below

Is the customer looking for QT support on RTOS?

If yes, we currently do not support QT on RTOS.

Hi Nikhil,

     Thanks for your reply.

     I'm not looking for QT support on RTOS.

     My question is  that when I use vx_single_camera_demo to display camera video output, I also want to display the QT HMI interface on LCD screen with camera video together.

     But when I run the QT HMI program when the camera video is displayed, it prompts that the QT output is in linuxfb, and there is no QT display output on the actual display screen. I think I need to configure the QT output buffer through viss, but I don't know how to configure it

hi,

Since single camera demo example uses Display node, we cannot run single camera demo + QT HMI together, because in this case, display is controlled by R5F and A72 cannot use it.. 

You probably require another node to receive single camera output and then display it using QT HMI.
