Scaling RGB

Herb Kutscha

I note that the HDVPSS scalers are 4:2:2. If I want to scale RGB input, can I use the GPU to scale captured RGB input, perhaps with a scaled BLT?

Hi, If you want to scale for displaying on TV, you can use HDVPSS graphics path scalar as well.

If the memory to memory bandwidth is acceptable, you can use the GPU. If there are 3D effects involved, OpenGL ES should be used, other wise PVR2D can be directly used.

Take a look at "test10" of sgxperf below for PVR2D usage, and "test3" for OpenGL ES usage.
