View Full Version : 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).
