Real-Time Loading in Images Frames/Video to Oculus Rift

Hi,

I am new to the Oculus Rift and I basically want to be able develop a program that will allow me to obtain the "current visual view" of the user. That current view can be though of an image frame. I want to do processing on that frame locally on my PC (i.e. edge detection), and then load the processed frame back into the view of the Oculus Rift.
I also will need to obtain the position coordinates. Do I need to do this all in C? C++?

Any help?

Thanks!
