Description
If intra period equals to GOP size, some statistics for adaptive maximum BT size are not initialized in sequential coding after first GOP, but are initialized in parallel coding of each segment at the start of encoder. Therefore, the coding results of sequential and parallel encoding are slightly different due to adaptive maximum BT size.
The mismatch only happens in coding the sequence SlideShow in class F of CTC, which has an intra period of 16 and is equal to GOP size.
