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 NOTE: The value of split_size must be an integer.
slice_output_en	Only 0 is supported.
reserved	This parameter is reserved. Currently, this parameter can only be set to 0.

Precautions

When split_mode is set to 1, pay attention to the LCU size of the current chip when the H.265 protocol is used.
