Jitter Destroying CPU – Can I use GPU?

March 10, 2010 | 3:04 pm

This may seem a stupid question as I’m not so sure what I’m talking about. Anyway, I have a patch that does camera tracking, live visuals and MSP synthesis and processing which seems just too much for my laptop.

A friend told me it is possible to move the jitter processing to the GPU, and while i know what a GPU is, I’m not exactly sure what this means or how I’d go about doing it.

I have an Intel MacBook Pro, on of the Core Duo models from 4 years ago so it has a good graphics card but not lot of RAM or CPU.

Thanks if anyone can help me.

Yup. Check out all of the Open GL tutorials. jit.gl.slab is your friend. Take a look at my optimization patches to get an idea of basics of moving video to the GPU.

Hi, check out the Video Processing System tutorials on this website for a good intro to working with GPU video processing.
