Hello,
I'm trying to build a system headless but I'm facing many questions. I'm using imx6-dual + GPU VIV GC2000.
I try to use fb1 to overlay a QT window on top of a gstreamer pipeline.
When I enable the fb1 there is a default alpha value making anything coming from QT translucide. Through other post in this forum I understand the value MXCFB_SET_GBL_ALPHA is set somewhere between 0 to 255 but I don't how to set it my self ?
I want to remove this global alpha on fb1 set by default to make my overlay QT window being opaque on the top of my video.
I built my system using Yocto-fido so with drivers : imx-gpu-viv_5.0.11.p4.5. It seems that I don't have access to any define to set the alpha values my self.
Please any help is welcome.
Jérôme.
