Detailed Description

Callback function type for a TrackingLost event (e.g. when a person leaves the frame).

It is guaranteed that this is the last callback for the pair <stream_id, track_id> (track_id is equal to sample.getID() for sample given in any VideoWorker callback).

So, after this callback, no Tracking, MatchFound or TrackingLost callback for the video stream stream_id can contain a sample with the same track_id.

Also it is guaranteed, that for each pair <stream_id, track_id> that was mentioned in the Tracking callback there will be exactly one TrackingLost callback.
