[directfb-dev] pixelformats

["FeNiX" <fenix@fly.srk.fer.hr>]

Hi!

I am using freevo with directfb output on tv. My graphic card is g400dh. One 
thing that is realy  bugging me is flickering when starting external apps 
like mplayer or xine. I figured out that this is because dfbmga and xine 
output plugin are reconfiguring layers and creating new surfaces. I was 
playing a little with dfbmga plugin and I was able to remove layer/surface 
initialization. I also made a little test app that made all that 
initialization for dfbmga. So when i run my app I had smooth transition 
between apps display content and mplayer.
Problem why I am writting is pixelformat. My app is using RGB16 pixelformat 
and that works fine on g400dh. Dfbmga is using YV12 pixelformat that (as I 
understood) enables accelerated video on g400 tv out. I can't use YV12 for 
my apps content or to be more general for freevo gui.
So is it posible to change pixelformat without flickering?
And is it posible to create window with YV12 surface on top of RGB16 
surface?
