Opened 13 years ago Closed 13 years ago #327 closed defect (fixed)AMP allowed at incorrect CU depths
Description
According to the binarization for part_mode, AMP partition modes are only possible when cLog2CbSize is greater than Log2MinCbSize.
The following code from HM-5.1 fails to implement this correctly.
The getMaxCUDepth function returns the total depth, taking into account both the minimum CU and minimum TU sizes. Therefore, depending on the minimum TU size, HM can potentially allow AMP even when cLog2CbSize = Log2MinCbSize.
Also, the "-1" in the for loop is not necessary. Attachments (1)Change History (5)comment:1 Changed 13 years ago by DefaultCC Plugin
