Backward Optical Flow output Using Optical Flow SDK sample

I am trying to use the Optical flow SDK 5.0.7 to output a backward flow from either a movie or .png frames. I got the SDK building and the sample building, but that is as far as I got. Is there an example of how to use and run the SDK perhaps? Even better it it a sample specific to simply outputting the flow data?

Update: Ohhh I was able to figure out that AppOFCuda sample outputs OF. I totally thought that was some sort of driver and did not think of looking into it. Now I just need a way to tell it do backward optical flow. Any ideas?

Thanks
