Description

Obtains the image processing result after a task is complete.

The VPC functional APIs are asynchronous (for example, vpc_crop). Therefore, it is necessary to call this API to obtain the processing result after the task processing is complete.

Prototype

C Prototype

        
             hi_s32 hi_mpi_vpc_get_process_result(hi_vpc_chn chn, hi_u32 task_id, hi_s32 milli_sec);

Python Function

        
             ret = acl.himpi.vpc_get_process_result(chn, task_id, milli_sec)

Parameters

Parameter	Description
chn	Int, channel ID for image processing.
task_id	Int, task ID. The task ID is used to determine the task whose result data needs to be obtained. The task ID can be obtained after the crop and resize APIs are called. For details, see acl.himpi.vpc_resize to acl.himpi.vpc_batch_crop_resize_make_border.
milli_sec	Int, timeout interval, in milliseconds.

Return Value

Return Value	Description
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VPC Return Codes.
