Hello..

 I am working on TMS320DM6437 digital media processor. 

I want two have two frame buffers two capture two subsequent frames from a camera source and calculate the optical flow between them. Currently I am able to get a single frame each time and operate on it. I have written basic edge detection working program using video_encdec template given in example folder. 

 Please someone get me idea how to go about declaring two frame buffer pointers in the program and store two successive frames in them. 

Please somebody help me..

Thanks and regards
