#580 closed defect (fixed)

unmatch over lossless coding

Reported by: spring Owned by:
Priority: critical Milestone: HM-7.0
Component: HM Version: HM-7.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

When I run the lossless coding under lowdelay configuration for sequence BQSquare_416x240_60.yuv or SlideEditing_1280x720_30, the decoder does not match the encoder. Can you help to fix this problem?

I use the default setting with the following flags set as 1.
LosslessCuEnabled : 1 # 1: Set "qpprime_y_zero_transquant_bypass_flag=1" and enable the lossless mode as well as the RD-based mode selection process.
TransquantBypassEnableFlag: 1 # Value of PPS flag.
CUTransquantBypassFlagValue: 1 # Constant lossless-value signaling per CU, if TransquantBypassEnableFlag is 1.
