hello everyone, i have some trouble in imx6q about ui and video combining.
i'm using buildroot for system (kernel 3.10 + QT5.5 + eglfs2.0 ). i want to play video and show transparent picture(eg: png) on the top of video.
my kernel boot args:"video=mxcfb0:dev=hdmi,1920x1080@60,if=RGB24,bpp=32 "
i have try some methods like this :
set video output to "video16"(BG),and set QT output to "fb1"(FG), this can work, but the background of "fb1" is not transparent and "fb1" have covered the video.
i tried to set the background of qt widget to transparent and set the "alpha"and"color_key" of fb1 device, but no effect both，or the settings is wrong ?
i also tried to set video output to "video16"(BG),and set QT output to "fb0"(BG), it will just show video only.
i can't find any demos for this, is there any method for my purpose ?
i'm look forward to you, thanks.
