I need to create an application that displays some graphics (using Qt) on the primary HDMI while also streaming video on the primary HDMI (that will be read from the sata interface). It looks like the best way to do this would be to use the v4l2 driver to stream the video and to overlay the video on the graphics. I am not quite sure how to configure the DM8168 to accomplish the overlay operation. Does anyone have any advice for me? Thx, Steve.
