Hello
i have implemented the standard MPeg4 deblocking filter. It is computationally expensive. So i decided to optimize it through SSE. But there are some constrants. As the deblocking filter work in two modes based on some condition.so we can not efficiently use the SSE.
Kindly any one knows the solution or it is already implemented.

Hi,
we do have IPP functions to implement deblocking filter for MPEG4. Why did not you use them?

Well let's us clarify the situation.
You said you downloaded the library. Could you please specify what version of IPP do you use?
Did you download IPP samples as well as IPP libraries?
If you have IPP installed youshould be able to build any IPP sample with using build.bat sript which is part of each IPP sample. Did you do that?
Regards,
Vladimir

Hi,
According IPP manual, Chapter 16 Video Coding, Article MPEG4, Postprocessing this function defined in ippvc.h and so you need to link with ippvc library.
Description
The functions
ippiFilterDeblocking_HorEdge_MPEG4_8u_I andippiFilterDeblocking_VerEdge_MPEG4_8u_I
are declared in the ippvc.h file. Thesefunctions perform deblocking filtering of two adjacent blocks on horizontal and vertical edges,
respectively (
[ISO14496], Annex F.3.1).Regards,
Vladimir
