Based from this link (http://software.intel.com/en-us/forums/topic/282021), I can use ippiYCbCr420ToRGB_8u_P2C3R to convert NV12 to BGR but I can't find any sample code on how to use the API. Could someone give me a simple code snippet? Say a 640x480 NV12 frame to a BGR of the same size? I'm new to IPP (using 7.1 now). What I'm particularly unsure of are these: const Ipp8u* pY, int pYStep, const Ipp8u* pCbCr, int CbCrStep parameters.
