I need to display UI based on OpenGLES on video, below is my configuration:
hdmi==>/dev/fb2 (BG) /dev/fb3(FG)
==>/dev/video17 /dev/video18
I config fb2 and fb3 to make them have the same resolution, and make in-pixel alpha blending work,
then I display UI on fb3, and use mfw_v4lsink to display video on /dev/video17, everything works well
except, mfw_v4lsink will blank HDMI when start to play a new song every time, because fb2 is primary
channel, and mfw_v4lsink will blank /dev/fb2.
I want to know how to fix it , or is there a workaround????
It is very strange I can't find the answer on Internet, don't many people have such desired to draw UI on video?
Thanks.
