Input Description

chn: int, image processing channel ID.

rotate_param: dict, rotation information dictionary. For details, see hi_rotate_param.

milli_sec: int, timeout interval (ms).
  • -1: blocking mode.
  • 0: non-blocking mode.
  • > 0: timeout interval (timeout mode). The timeout interval varies with the operating system. The deviation is generally within a time slice of an operating system. For example, if the time slice of an operating system is 4 ms and the value of milli_sec is set to 1, the actual timeout interval ranges from 1 ms to 5 ms. When the CPU load is high, the timeout interval may fluctuate.

Return Value

ret: int, error code.

task_id: task ID, used to identify a task.
