Hi Robert,

please note that IPP JPEG codec (part of JPEGView sample) use OpenMP threading. To enable that you need to compile it with Intel C/C++ compiler with sample's build script or you need to specify /Qopenmp option for ICL or /openmp option for VC2005 compilers if you use VC studio project.

The second point, it is better to link codec with IPP static libraries.

With all these conditions our test show that IPP JPEG codec is the fastest codec between (IJL 1.5, IJL 2.0 and IJG JPEG codecs).

Regards,
  Vladimir
