The syntax element that controls the sub-pu tmvp block size is named differently at the decoder (slice_atmvp_subblk_size_log2) and the encoder (log2_slice_sub_pu_tmvp_size_minus2). When doing a diff between encoder and decoder traces, this pops up. The suggestion is to harmonize the naming to log2_slice_sub_pu_tmvp_size_minus2.
