Parameter

Input/Output

Description

vi_pipe

Input

Pipe ID.

Value range: [0, 12)

vi_chn

Input

VI channel ID.

Value range: [0, 1)

dis_attr

Input

Pointer to the DIS attribute structure.

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

DIS attributes can be set after the VI channel is enabled by calling hi_mpi_vi_enable_chn and the DIS function is configured by calling hi_mpi_vi_set_chn_dis_config.
If you call this API to enable the DIS function, do not call hi_mpi_vi_set_pipe_pre_crop to enable the channel cropping function. To use the cropped image for the DIS, you are advised to crop the image at the front end of the MIPI or pipe.
Before modifying the DIS configuration or channel attributes, disable the DIS function.
