- only cu_qp_delta is conditioned by (CbWidth > 64 || CbHeight > 64)
- move parsing of tu_joint_cbcr_residual_flag[] between cu_chroma_qp_offset_idx and transform_skip_flag instead of before cu_qp_delta

numCandminus1_step is always positive

- This fix is aligned with spec text.

Software changes with respect to the adoption from proposal JVET-O0455:

1. indentation
2. function naming
3. Class declaration positions

initial commit of JVET_O0119_BASE_PALETTE_444: palette in HEVC and palette mode coding in JVET-N0258

Jonathan Taquet authored 5 years ago and Karsten Suehring committed 5 years ago

includes offline discussed replacement of tb(v) by ue(v) coding for alf_chroma_num_alt_filters_minus1

It cleans up old ISP code that is no longer used anymore. The code was used to allow only one ISP split depending on the block size. However, this functionality is not needed anymore after the adoption of JVET-N0308 during the Geneva Meeting in March, which limited the usage of ISP to CUs with a maximum size of 64x64 samples. This clean-up eliminates various unnecessary checks and improves the readability of the code.
