Video Post Processor, Scaling

[atiflz]

How can I use video post processor on the MMSP2? Documents are really hard to find. I just want to upscale an image to fullscreen.

Using HW accelerated SDL, you can just set the video mode to the size of the image(as long as its width is a multiple of 8), and it will resize it i think

Unless of course you want smooth scaling, in which case it's more complicated, but certainly needs to be in YUV rather than RGB. There are people around who know how to do it, though, I believe.

If you don't want SDL, and blocky scaling is ok for you, see MLC_STL_HSC and MLC_STL_VSC in MMSP2 Databook here:

Actually, I want smooth scaling without SDL. I can write some routines but they will be inefficient.
