InputFrameThrottler Class

Description

Input frame throttler.

There is a input frame input port and a input frame output port. It can be used to prevent incoming frames from entering algorithm components when they have not finished handling previous workload.

InputFrameThrottler occupies one buffer of camera. Use setBufferCapacity of camera to set an amount of buffers that is not less than the sum of amount of buffers occupied by all components. Refer to Overview .

All members of this class is thread-safe.

It shall be noticed that connections and disconnections to signalInput shall not be performed during the flowing of data, or it may stuck in a state that no frame can be output. (It is recommended to complete dataflow connection before start a camera.)
