Hi
Im wondering how to add graphics to an app like - fbtv using overlay.
As I understand overlay the videocard writes directly to the videomemory ?!
I would like to add graphics on top of the tv-image - but dont know how to
do this.
I have tried grabbing using Gerd's suggestion from the documentation in
libng -
that suggest grabbing frame 0, then frame 1 - then sync frame 0 - and
process it (for me meaning adding graphics to it) then sync frame 1 ...etc.
This works but is too slow. (I have old hardware)
So now I want to write directly to the framebuffer and let the videocard do
the same....
(How) can I do this ? and what about syncing ?? And is this the way to do it
at all ??
- A Newbie!
