Hi,
Our setup is like data from android surface flinger is available "/dev/graphics/fb0"
We want to do overlay with CSI buffer which is written on "/dev/graphics/fb1"
We are able to get it working with global alpha and colour keying. But due to some limitation with our GUI we can not use global alpha.
But If I disable global alpha and enable the local alpha than data from /dev/graphics/fb1 is not display.
- Is it possible to do alpha blending using local alpha without colour keying?
- What is a significance of alpha_phy_addr0, alpha_phy_addr1 and alpha_in_pixel?
Thanks
Saurabh
