Restrictions

• Before calling this API, you must call the hi_mpi_isp_sensor_reg_callback API to register the sensor with the ISP.
• Multiple processes are not supported. This API must be called in the same process as hi_mpi_isp_sensor_reg_callback, hi_mpi_isp_ae_lib_reg_callback, hi_mpi_isp_awb_lib_reg_callback, hi_mpi_isp_init, hi_mpi_isp_run, hi_mpi_isp_exit, hi_mpi_ae_register, and hi_mpi_awb_register.
• This API cannot be called when the current service is running the hi_mpi_isp_run API.
• You are advised to call this API to reinitialize the module after calling hi_mpi_isp_exit.
• When the same vi_pipe is used, multiple threads cannot be used for ISP creation or destroying (multiple threads cannot call hi_mpi_isp_sensor_reg_callback, hi_mpi_isp_ae_lib_reg_callback, hi_mpi_isp_awb_lib_reg_callback, hi_mpi_isp_init, hi_mpi_isp_run, hi_mpi_isp_exit, hi_mpi_ae_register, and hi_mpi_awb_register at the same time).
