Detailed Description

Callback function type for a Tracking event. This callback is called every time the frame has been processed by the tracker. Tracking callback will be called with frame_id = X not earlier than VideoWorker.addVideoFrame returns the value X + N - 1, where N is the value returned by VideoWorker.getTrackingConveyorSize.

Tracking callbacks with the same stream_id are called in ascending frame_id order. So, if you receive a callback with stream_id=2 and frame_id=102 right after a callback with stream_id=2 and frame_id=100, then the frame with frame_id=101 was skipped for the video stream 2.
