Error of h.264 decoder

[rinusia]

Hello.

We study about software codec solution.

IPP shows very dramatic performance enhance in decoding & encoding.

It is very interesting~!

But H.264 decoder sample has a error.

H.264 decoder showed some artifacts (black rectagles) in motion estimation.

We could not find where this error occurs ( IPP lib or sample decoder?).

Also, To add and expand the decoding & encoding functionarity of Pentium chip, we have some request.

Please check following comment !! and thank you~

1. H.264 decoder sample have serveral limitation. Does Intel have any plan to release H.264 compliant decoder ?

2. Could Intel open and release the C-source of your h.264 library. or could we buy it with IPP library? ( API document have some limitation to explain its functionarity)

3. Could you fix the error at h.264 decoder? h.264 decoder shows some artifact at decoding the bitstream encoded by JM90. we add cofiguration file and attach encoded bitstream.

Thank you..

Dear Customer,
Thanks for your interest in Intel IPP.

->1. H.264 decoder sample have serveral limitation. Does Intel have any plan to release H.264 compliant decoder ?

The current H.264 decoder sample and encoder sample provided in Intel IPP 4.1 support JM 7.3. You may download and check the latest video sample update from http://www.intel.com/software/products/ipp/samples.htm (Click "Windows* in a row for Video group) We corrected an issue of the mismatches in protocolsfor H.264 codec samples. We suggest you to rebuild with the latest sample to see how it works. If the problem still persists,

pleasesubmit a detailed issueincluding yourraw YUV file andsample .par file via Intel Premier Support (https://premier.intel.com) , we willlook into it.

-> 2. Could Intel open and release the C-source of your h.264 library. or could we buy it with IPP library? ( API document have some limitation to explain its functionarity)

Intel does not offer or release any source code of our libraries.

->3. Could you fix the error at h.264 decoder? h.264 decoder shows some artifact at decoding the bitstream encoded by JM90. we add cofiguration file and attach encoded bitstream.

Please see my response in #1 listed above.

Hope it helps.
Thanks,
Ying
