In the branch HM-9.0-dev:

the code in TDecTop::xDecodeSEI -> "m_SEIs = m_pcPic->getSEIs()" always got pointer NULL, so the decoder crash here.

and decoder can't found/verify checksum when use suffix SEI.

Equations 8-108 etc. Input taps for f,g,k,i,p,q are incorrectr - the 3x3 block of positions that require 2d filtering seem to be transposed. e.g. f should be based on b rather than a terms

In the WD5(G1103-d1) Talbe 8-4, I guess it have some mistake with HM-5.0. I have checked the function here, the function codeIntraDirChroma and parseIntraDirChroma see like use Table 8-5 always.

The mistake in the Table 8-4 are:

1. intra_chroma_pred_mode=1 and IntraPredMode=2 or 3
2. intra_chroma_pred_mode=2 and IntraPredMode=3
