RDOQ missing support for chroma QP offsets

Reported by: lkerofsky Owned by:
Priority: minor Milestone: HM-9.2
Component: HM Version: HM-9.1
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

The chroma distortion weighting in RDOQ does not account for chroma QP offsets. A patch is attached which uses separate weights for Cb and Cr, computes the weights using appropriate QP offsets, includes the chroma format in RDOQ function calls to select the appropriate weight.

The patch seems to have some issues:

  • In the last modification in TEncSearch.cpp, uiDistortionBest is replaced by uiDistortion. Copy-paste gone wrong?
  • "i" prefix should be avoided in names of variable introduced in TEncSlice.cpp
  • Int type should be used instead of int in TComRdCost.cpp
