IMX6 How to exchange with fb1 and fb0 ? Now display the UI in fb0 , The fb1(/dev/video17) display video. I want to make the UI cover video?
normally, we set fb0 as graphics and set fb1 as foregroud,
if You must play video as background and graphics as overlay, you need to open fb0 for your video playback and fb1 as your graphics in your set up. You can set your alpha either local or global based on your needs.
I send a sample code for alpha blending, hope helpful for you.
Problem has been resolved. Thanks
