Creating a transparent menu on top of a Qt display and video playback simultaneously

Marlon Smith

Hi everyone,

I'm working on an application for the DM365 which displays a video in the top corner of the screen and uses Qt to draw graphics to the rest of the screen.  I'm using framebuffer device 2 to control which parts of the screen display video and which parts display my Qt graphics.

I would like to create a transparent menu, and display it over top of my current display (video and graphics).  The problem is that I have already used the hardware blending capabilities to control my video and Qt, so there is no way to blend another display on top.  I can create a translucent Qt window, which will display over top of the Qt portion of the screen, but it does not display over top of the video.

Does anyone have any ideas?

Thanks!

Marlon
