Hello,
I am working on LCD module and I want to implement two overlay windows
on frame buffer. I have some queries related to this:
1. Can any buddy suggest me how to proceed towards it??
2. Is their any standard way to use frame buffer ioctl calls??
3. If i have to define my own ioctls then how application manage it??
Thanks and Regards
Vipul Samar

You mean capture overlay windows? E.g. you want to capture from a video input
and have the video directly rendered in the framebuffer?
The "Video Overlay Interface" section in the V4L2 specification describes how
to do that, but it also depends on whether the V4L2 driver in question
supports that feature.
It might be that you mean something else, though.
