Parameter	Input/Output	Description

dis_config	Input	Pointer to the DIS configuration information structure.

Parameter

Input/Output

Description

vi_pipe

Input

Pipe ID.

Value range: [0, 12)

vi_chn

Input

VI channel ID.

Value range: [0, 1)

dis_config

Input

Pointer to the DIS configuration information structure.

This API can be called only after a VI pipe is created by calling hi_mpi_vi_create_pipe.

When you call this API to set hi_dis_config.scale to HI_TRUE and call hi_mpi_vi_set_chn_dis_attr to enable the DIS function, crop_ratio in the DIS configuration can be dynamically modified when the DIS function is enabled. To modify the DIS configuration parameters in other cases, disable the DIS function by calling hi_mpi_vi_set_chn_dis_attr before modification as the parameters cannot be dynamically modified.
