Hello,
I faced with a problem when setting the local alpha blending.
Use 2 framebuffer:
**fb0** for my qt application (widget with a black background and green text information);
**fb1** for outputting a video camera using gstreamer 1.0
Configurable global alpha blending, but when mixed are black pixels around the green text.
I decided to try the local alpha blending, but do not know how to reconfigure from 24-bit to 32-bit.
P.S. I use assembly console-trdx-image 2.6
**Update**
I reconfigured frame buffer but now my app is displayed over the video and the local alpha blending does not work.
