Hello all,

Is it possible to Deinterlace images with OpenGL ? If yes:

1 - Is it faster as the equivalent method using MMX ?
2 - Is the result as good as, or better ?

I'm searching it in google but until now no luck.
I'm also trying to find any libraries from NVIDIA/ATI that would do
it, is there such a thing !? I thought I would find something under
nv_image_processing.lib, but there is nothing.

TIA.

Sure it is possible, and with Pixel Shaders it can be even quite
fast.

Measure it.

With Pixel Shaders you can get the same quality.

If you want to write a video player software, OpenGL can be used,
I'd recommend to use a video overlay. BTW: Both recent ATI and
nVidia GPUs have special units for deinterlacing, which are only
functioning with such overlays. But don't ask me, how to enable
these.
