Hi all,
I am writing a directX transform filter that is included into a directX filterGraph that streams avi file and render each frame to the screen.
I would like to do some image processing (low-pass and down-sampling) on each frame in the transform filter. I can access each frame as an array of BYTE (rgb 24 bits per pixel). Is there a way to do low-pass and down-sampling operation without using low-level processing ? Ideally I would like to use the video card memory.
Thanks
Lauren
