Hi,

I'm trying to render live video to an openGL surface, the current way it has been done is to use DirectShow to grab the frames and use glTexImage2D and glTexSubImage2D thereafter to create the textures to display. Is there are faster way to do this? are there any faster alternatives to glTexImage2D and glTexSubImage2D? and finally, I'm assuming that these two functions are using the GPU on the ASUS card rather than the PC's CPU?

Many thanks in advance!
