#1515 fixed The possible editorial changes related WPP Yue Yu yyu2021
Description

In the current HEVC specification(11/2019), some places (9.3.1 and 9.3.2.1) use TableStateIdxWpp, TableMpsValWpp, TableStatCoeffWpp, PredictorPaletteSizeWpp and PredictorPaletteEntriesWpp, but some places (9.3.2.4 and 9.3.2.5) use tableStateSync, tableMPSSync, tableStatCoeffSync, PredictorPaletteSizeWpp and PredictorPaletteEntriesWpp. Suggest to correct this inconsistency.

#1509 invalid mismatches in PCM alignment syntax wangli
Description

In the spec, we have the syntax below. while (!byte_aligend())

pcm_alignment_zero_bit

However, it need to write "1" before align zero in HM. Void TEncBinCABAC::encodePCMAlignBits() {

finish(); m_pcTComBitIf->write(1, 1); m_pcTComBitIf->writeAlignZero(); pcm align zero

}

Could anyone help to check if it is a mismatch? Thx

#1506 fixed film grain SEI encoder use wrong bits to signal num_model_values_minus1 taoranlu
Description

The syntax element num_model_values_minus1 should be signaled with 3 bits according to spec. The encoder SEI function xWriteSEIFilmGrainCharacteristics() mistakenly uses 8 bits. The decoder parsing is correct.
