IPP samples bug in jpegenc.cpp

IPP samples bug in uic_jpeg_enc.h

In UIC sample 6.1.4.059, the code in jpegenc.cpp on line 2031 seems to be bad:

buflen = (m_jpeg_mode == JPEG_LOSSLESS) ?
IPP_MAX(ENC_DEFAULT_BUFLEN,m_numxMCU * m_jpeg_ncomp * 2) :
ENC_DEFAULT_BUFLEN;

I guess it should be:

buflen = (m_jpeg_mode == JPEG_LOSSLESS) ?
IPP_MAX(ENC_DEFAULT_BUFLEN,m_numxMCU * m_jpeg_ncomp * 2 * 2) :
ENC_DEFAULT_BUFLEN;

This was also indicated elsewhere in this forum.

I was expecting this latest IPP 6.1.4 update to have included these fixes.

Hi Thomas,

This will be fixed in the next major version of IPP.

Vladimir
