I am having a strange problem using Intel ipp jpeg compression for my 64 bit windows application... the color conversion function ippiBGRToYCbCr_JPEG_8u_C3P3R defined in ippj.dll gets bizare frequently and seems like it stucks somewhere and gets slower. its quite random but I did some timing checks and it seems that this function does not work properly for me. Same function in 32 bit dll is working fine but in 64 bit its creating problem. Can anyone help me please.. If somebody wants i can upload the compression timing test which i made.
