Hello,

you can take a look on our JPEG2000 sample, which demonstrate how to implement JPEG2000 codec with IPP functions. Sample's build scripts do not support WinCE, but I hope you can port it for your needs.

By the way, are you talking about IA32 based system or about Xscale based system?

Regards,
Vladimir

Any kind souls has done this care to share your experiences ?

Also, is there any way to implement ippiConvert_8u32f_C1R in Xscale or any way to replace it ?

Any help is greatly appreciated !

Thanks !

Hello,

it seems you use old version of IPP JPEG2000 sample. From IPP 5.1 we do not use ippiConvert_8u32f_C1R function in JPEG2000 sample. Please update with the latest version of sample (which is from IPP 5.1.1). Note, you need to define XSCALE macro in order to exclude IPP functions, which are not supported on Xscale (mostly those which works with Ipp64f and Ipp32f data types)

Vladimir
