I found that theare is no " umc_color_space_converter.h".

so i cann't compile this source..

where can i "umc_color_space_converter.h" file.

of course, i'm using the source code sample from this site...

but i don't have "umc_color_space_converter.h"

Hello,

The file umc_color_space_converter.h was used in previous versions of this sample and was removed in the latest version (IPP 5.2 gold).

Please make sure you have installed IPP 5.2 gold libraries and samples and you have extracted source code from umc_manual.pdf from the latest version of IPP media sample.

Regards,
Vladimir

Thank you Vladimir.

first of all,I have installed IPP 5.2. but I can not make sure it's gold version.....

AndI have sample code ("w_ipp-samples_p_5.2.049"). i think it's the last sample code version.

then, Can i get mpeg4 decoder sample code based on IPP5.2 library?

And, if iuse mpeg4 decoder based on "UMC_DOC_SAMPLE" (previous version),

does the decoder performance(speed..) decreased?

==> If not, Where can i get "umc_color_space_converter.h" file?

Thank you.

He Lee,

let me clarify this. In umc_manual.pdf we have piece of sample code which demonstrate how to build simple motion JPEG decoder (note, not MPEG4 decoder). We keep this sample updated with the latest changes in UMC file set and structure.

Then, on this forum, in some of threads there were published modification of this piece of code to substitute motion JPEG with MPEG4. Of course, with a time this might became out-dated, so you need to extract piece of code from your version of umc_manual.pdf file and modify it accordingly (because, as I said before,the file umc_color_space_convertor.h was removed from the latest version of UMC)
