Members

Member	Description
split_enable	Slice split enable. 0: disabled (default). 1: enabled.
split_mode	Slice split mode. Currently, this parameter can only be set to 1, indicating splitting by macroblock row or LCU row.
split_size	For H.264: number of macroblock rows occupied by each slice. Maximum value: (Image height + 15)/16 Minimum value: (Maximum value + 15)/16 For H.265: number of LCU rows occupied by each slice. Maximum value: (Image height + LCU – 1)/LCU Minimum value: (Maximum value + 15)/16
slice_output_en	Only false is supported.
reserved[2]	This parameter is reserved. Currently, this parameter can only be set to 0.

Precautions
