Description

Deinitializes the low-level hardware of the media data processing system after media data, such as images and videos, is processed. Repeated calls to this API return no failures.

This API must be called before runtime resources are deallocated. For details, see Runtime Resource Allocation and Deallocation.

Prototype

hi_s32 hi_mpi_sys_exit(hi_void)

Parameters

None

Returns

0: success
Other values: failure. For details, see Common Return Codes.

Restrictions

After this API is called for deinitialization, the resources for processing media data in the system are released. Therefore, APIs (except hi_mpi_sys_init) in the media data processing V2 section cannot be called. Otherwise, exceptions may occur during API calling or the return code may be incorrect.
