Parameters

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing.
blend_param	Input	Blending parameter
task_id	Output	Pointer to the task ID, used to identify a task.
milli_sec	Input	Timeout interval, in 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.
