I have a system of ui ,and it is base on Directfb library.It is running on imx53.
So the graphic layer of system is created by Directfb,and not created by imx-lib of IPUV3.
Now,I need to close colorkey and open alpha by imx-lib.
I don't know how to do.
Can I get address of overlay physical buffer by mxc_ipu_lib_task_buf_update(), and close colorkey by Overlay buffer parameter( struct: ipu_lib_overlay_param_t )?
Can any one help me?
