[Linux-fbdev-users] graphic overlay/mixing question

[Niklas F. <nik...@ti...>]

Hi all,
I have a question that might be off topic but after searching the net
and mailing lists I give in and hope for some help on this list.

I wonder what the best way to mix graphics written to a framebuffer over
decoded video is. I can't change the way the graphics is written to the
device, it has to be directly to a linux framebuffer device.

My hope is that there are some generic way of doing it without bying a
fancy XYZ graphics card but if I must I'll do that.

Flow overview:
userapp -> /dev/fb1
player -> /dev/fb0
The graphics would be either with CHROMAKEY transparency 16bpp or 32 bpp
ARGB

Kind regards 
Niklas Fondberg
