So this fix does not change BD-rate results. In order to align WD description and software, it is recommended to fix this issue when HM-6.0 is released. Attachment is a patch to HM-5.1-dev-cleanup. #define FIX_CU_DQP_WRAP 1 ///< Fix wrapping of cu_qp_delta #if FIX_CU_DQP_WRAP #define RESET_QP_OFFSET 1 ///< This macro shall be set equal to 0 or removed when JCTVC-H0400 is integrated. #endif There is another issue that the QpBdOffsetY may not be used appropriately in HM software. (This issue is also related to ticket #313.) It is recommended that the RESET_QP_OFFSET macro is also integrated into HM-6.0 in order to avoid its impact on the QP wrapping fix. Then RESET_QP_OFFSET macro should be removed when JCTVC-H0400 is integrated. " defect closed minor HM-6.0 HM HM-5.1 fixed QP wrapping fbossen ksuehring davidf jct-vc@…
