[Solved] How does a GPU decode video?

This is kind a technical I guess. Please explain how a GPU actually decodes video in an accelerated manner? Is it very much analogous to video decoding done by CPU? Please explain in steps. Thanks in advance.

  1. You are asking for a detailed description of how CUDA (Nvidia) or STREAM (ATI/AMD) works. I suggest you to those respective sites (nvidia.com and ati.com) and research the various whitepapers that are available.

    Why are you asking? This sounds like an academic question.

    Good luck!
  2. I was just curious. Now I got the idea. Anyways thanks for your suggestion 'COLGeek'.
