H.264 - at least one optimized deblock function is incorrect

I'm on Penryn (P9500), hence _p8_ownFilterDeblockingChroma_HorEdge_H264_8u_C1IR_V8 is used, which gives different result compared to both JM and unoptimized IPP version. (both 6.0 and latest 6.1 upd1)

Bug is committed to premier support - posting here just to let others know, that output of H.264 encoder/decoder in 4:2:2 mode is corrupted for chroma on Core 2/Xeon5100 series and higher.

Thanks for informing here. When you link with IPP static libraries you may choose to dispatchCore2 optimized code (V8 libraries) instead of Core i7 optimized code where you discover the issue (P8). You may dispatch processor specific code with ippStaticInitCpu call.

Has this issue been fixed? And if so, when will it be available? I assume that the issue exists in the latest 6.1-1 as well...

Hi Jay,

I think it should be fixed in the latest update. Sorry, can't provide exact answer right now (do not have the issue number to check with data base).
