They used to have a section on the site encoding video at over 100fps (way faster than real-time), and comparing it to Xeons.
Even searching for it doesn't show the results.....
Anyways, point is the Shader Model 3.0 cards can be programmed using 'Sh' for example, and video encoding applications are usually coded in C/C++.
'Sh' and C/C++ are very similar, so the routines that do the bulk of the encoding can be ported easily.
Checked
http://sourgeforge.net and only a few basic projects there too.
I know Adobe Premiere Pro can offload to the GeForce 7000 series GPU to process certain effects, etc, and possibly the final video, very quickly considering.
- Sorry for the life of me I can't find the links on the nVidia site. During the MPEG4 buzz they had a whole section on it.
Could e-mail them and ask maybe ?
