TDA4VH-Q1: Could display image be dynamically modified while graph is running?

Part Number: TDA4VH-Q1

Hi,

I'm trying to display different images while running vxProcessGraph.

I tried this by modifying display_image in the for loop where I run vxProcessGraph, but the display image didn't change.

For example, in this for loop, I hope the display image will change after the 50th iteration.

        for(int i = 0; i < 100; i++)
        {
            if (i < 50) {
                obj->display_image = image1

            } else {
                obj->display_image = image2
            }
            status = vxProcessGraph(this->obj->graph);
            vxReleaseImage(obj->display_image);  
        }

Could display image be dynamically modified while graph is running?
