    hardware decoding of mpg/h264 - looking for a starter

    Hi all,

    i have heard about various current
    gpus / graphics boards with embedded
    dvd decoders.

    i want to play a dvd stream and
    then apply some shader fx on it
    and then do some distortions etc.

    does anyone know how to do this
    with a current nvidia/ati
    hardware piece?
    is this possible using opengl?

    with the best regards,

    To make use of GPU hardware decoding you will have to use DirectShow.

    If you want to perform some shader effects on the decoded frame:
    Using Direct3D VMR9 you could grab the decoded frame on the gpu into a texture and do what ever you want.

    Using OpenGL, you probably have to query DirectShow for the decoded frame into CPU memory and load it onto the GPU (OpenGL texture).
