H.264 decoder crash

[Enrico_Viarani]

Hi all.I'm using IPP 7.0.4.I have got a crash with the H264 decoder when I'm decoding the first frame coming from a Samsung H264 camera.

The crash appens in the UMC::H264SegmentDecoder::InitDeblockingOnce() method, accessing indexm_CurMBAddr == 80, ofm_gmbinfo->mbs[] array. Inspecting memory, it seems that this array i valid only in the range [0-53].

This is the stack-trace:

UMC::H264SegmentDecoder::InitDeblockingOnce()

UMC::H264SegmentDecoder::DeblockSegment(int iFirstMB=80, int nBorder=160)

UMC::H264SegmentDecoderMultiThreaded::DeblockSegmentTask(int iCurMBNumber=80, int & iMBToProcess=5120)

UMC::H264SegmentDecoderMultiThreaded::ProcessSegment()
