hi_mpi_sys_exit

Description

Deinitializes the low-level hardware of the media data processing system after media data, such as images and videos, is processed.

Restrictions

• Repeated calls to this API return no failures.
• 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.
• This API must be called before AscendCL runtime resources are released. For details about how to allocate AscendCL runtime resources, see Runtime Resource Allocation and Deallocation.
