hi_mpi_isp_ae_lib_reg_callback

Applicable Products

Description

Registers the callback functions of the AE algorithm library with the ISP.

Prototype

hi_s32 hi_mpi_isp_ae_lib_reg_callback(hi_vi_pipe vi_pipe, const hi_isp_3a_alg_lib *ae_lib, const hi_isp_ae_register *ae_register)

Parameters

Returns

• 0: success
• Other values: failure. For details, see Error Codes.

Constraints

• If you use the AE algorithm library, this API can be ignored. If you use your own AE algorithm library, you need to call this API to register callback functions with the ISP.
• This API does not support multiple processes.
• A maximum of two AE libraries can be registered.

Example

hi_isp_ae_register ae_register;
hi_s32 ret = HI_SUCCESS;
ae_register.ae_exp_func.pfn_ae_init = ae_init;
ae_register.ae_exp_func.pfn_ae_run = ae_run;
ae_register.ae_exp_func.pfn_ae_ctrl = ae_ctrl;
ae_register.ae_exp_func.pfn_ae_exit = ae_exit;
ret = hi_mpi_isp_ae_lib_reg_callback(vi_pipe, ae_lib, &ae_register);
if (HI_SUCCESS != ret) {
    printf("Hi_ae register failed!\n");
}
